This file attempts to describe the rules to use when hacking Bison.
|
||||
Don't put this file into the distribution. Don't mention it in the
|
||||
ChangeLog.
|
||||
|
||||
Everything related to the development of Bison is on Savannah:
|
||||
|
||||
http://savannah.gnu.org/projects/bison/
|
||||
|
||||
|
||||
* Administrivia
|
||||
|
||||
** If you incorporate a change from somebody on the net:
|
||||
First, if it is a large change, you must make sure they have signed
|
||||
the appropriate paperwork. Second, be sure to add their name and
|
||||
email address to THANKS.
|
||||
|
||||
** If a change fixes a test, mention the test in the ChangeLog entry.
|
||||
|
||||
** Bug reports
|
||||
If somebody reports a new bug, mention his name in the ChangeLog entry
|
||||
and in the test case you write. Put him into THANKS.
|
||||
|
||||
The correct response to most actual bugs is to write a new test case
|
||||
which demonstrates the bug. Then fix the bug, re-run the test suite,
|
||||
and check everything in.
|
||||
|
||||
|
||||
* Hacking
|
||||
|
||||
** Visible changes
|
||||
Which include serious bug fixes, must be mentioned in NEWS.
|
||||
|
||||
** Translations
|
||||
Only user visible strings are to be translated: error messages, bits
|
||||
of the .output file etc. This excludes impossible error messages
|
||||
(comparable to assert/abort), and all the --trace output which is
|
||||
meant for the maintainers only.
|
||||
|
||||
|
||||
* Test suite
|
||||
|
||||
** make check
|
||||
Use liberally.
|
||||
|
||||
** Release checks
|
||||
Try to run the test suite with more severe conditions before a
|
||||
release:
|
||||
|
||||
- Configure the package with --enable-gcc-warnings, so that one checks
|
||||
that 1. Bison compiles cleanly, 2. the parsers it produces compile
|
||||
cleanly too.
|
||||
|
||||
- run `make maintainer-check' which:
|
||||
- runs `valgrind -q bison' to run Bison under Valgrind.
|
||||
- runs the parsers under Valgrind.
|
||||
- runs the test suite with G++ as C compiler...
|
||||
|
||||
- Change tests/atlocal/CFLAGS to add your preferred options. For
|
||||
instance, `-traditional' to check that the parsers are K&R. Note
|
||||
that it does not make sense for glr.c, which should be ANSI,
|
||||
but currently is actually GNU C, nor for lalr1.cc, which anyway is
|
||||
not exercised yet in the test suite.
|
||||
|
||||
|
||||
* Release Procedure
|
||||
|
||||
** Try to get the *.pot files to the Translation Project at least one week
|
||||
before a stable release, to give them time to translate them.
|
||||
|
||||
** Tests
|
||||
See above.
|
||||
|
||||
** Update the foreign files
|
||||
Running `./bootstrap' in the top level should update them all for you.
|
||||
This covers PO files too. Sometimes a PO file contains problems that
|
||||
causes it to be rejected by recent Gettext releases; please report
|
||||
these to the Translation Project.
|
||||
|
||||
** Update NEWS
|
||||
The version number, *and* the date of the release (including for
|
||||
betas).
|
||||
|
||||
** Update ChangeLog
|
||||
Should have an entry similar to `Version 1.49b.'.
|
||||
Check all this in once `make distcheck' passes.
|
||||
|
||||
** make alpha
|
||||
Running `make alpha' is absolutely perfect for beta releases: it makes
|
||||
the tarballs, the xdeltas, and prepares (in /tmp/) a proto
|
||||
announcement. It is so neat, that that's what I use anyway for
|
||||
genuine releases, but adjusting things by hand (e.g., the urls in the
|
||||
announcement file, the ChangeLog which is not needed etc.).
|
||||
|
||||
If it fails, you're on your own...
|
||||
|
||||
It requires GNU Make.
|
||||
|
||||
** Upload
|
||||
Put the tarballs/xdeltas where they should be. Or put it somewhere,
|
||||
and send the URL to [email protected].
|
||||
|
||||
** Bump the version number
|
||||
In configure.ac. Run `make', check this in.
|
||||
|
||||
** Announce
|
||||
Complete/fix the announcement file, and send it at least to
|
||||
[email protected] (if a real release, or a ``serious beta''),
|
||||
[email protected], [email protected], [email protected],
|
||||
and [email protected].
|
||||
|
||||
Send the same announcement on the comp.compilers newsgroup by sending
|
||||
email to [email protected]. Do not make any Cc as the moderator will
|
||||
throw away anything cross-posted or Cc'ed. It really needs to be a
|
||||
separate message.

** Internationalization
|
||||
Bison supports two catalogues: one for Bison itself (i.e., for the
|
||||
maintainer-side parser generation), and one for the generated parsers
|
||||
(i.e., for the user-side parser execution). The requirements between
|
||||
both differ: bison needs ngettext, the generated parsers do not. To
|
||||
simplify the build system, neither are installed if ngettext is not
|
||||
supported, even if generated parsers could have been localized. See
|
||||
http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
|
||||
more details.
|
||||
Bison can work with pre-1.4.3 distributions of GNU m4 if they are
|
||||
sufficiently patched, but if you encounter a bug with an older
|
||||
distribution and report a bug we will probably suggest that you
|
||||
upgrade to 1.4.3 as the first step in trying to fix it.

||||

* Administrivia
|
||||
|
||||
** If you incorporate a change from somebody on the net:
|
||||
First, if it is a large change, you must make sure they have signed
|
||||
the appropriate paperwork. Second, be sure to add their name and

||||
email address to THANKS.
|
||||
|
||||
** If a change fixes a test, mention the test in the commit message.
|
||||
|
||||
** Bug reports
|
||||
If somebody reports a new bug, mention his name in the commit message
|
||||
and in the test case you write. Put him into THANKS.
|
||||
|
||||
The correct response to most actual bugs is to write a new test case
|
||||
which demonstrates the bug. Then fix the bug, re-run the test suite,
|
||||
and check everything in.

Bison is written using Bison grammars, so there are bootstrapping issues.
|
||||
The bootstrap script attempts to discover when the C code generated from the
|
||||
grammars is out of date, and to bootstrap with an out-of-date version of the
|
||||
C code, but the process is not foolproof. Also, you may run into similar
|
||||
problems yourself if you modify Bison.

|
||||
|

Only building the initial full source tree will be a bit painful. Later,
|
||||
after synchronizing from the repository a plain 'make' should be sufficient.
|
||||
Note, however, that when gnulib is updated, running './bootstrap' again
|
||||
might be needed.

** First checkout

* First checkout
|
||||
|
||||
Obviously, if you are reading these notes, you did manage to check out
|
||||
this package from the repository. For the record, you will find all the
|
||||
relevant information on:
|
||||
|
||||
http://savannah.gnu.org/git/?group=bison
|
||||
|
||||
Bison uses Git submodules: subscriptions to other Git repositories.
|
||||
In particular it uses gnulib, the GNU portability library. To ask Git
|
||||
to perform the first checkout of the submodules, run
|
||||
|
||||
$ git submodule update --init
|
||||
|
||||
Git submodule support is weak before versions 1.6 and later, you
|
||||
should probably upgrade Git if your version is older.
|
||||
http://savannah.gnu.org/cvs/?group_id=56
|
||||
|
||||
The next step is to get other files needed to build, which are
|
||||
extracted from other source packages:
|
||||
|
||||
$ ./bootstrap
|
||||
$ ./bootstrap
|
||||
|
||||
And there you are! Just
|
||||
|
||||
$ ./configure
|
||||
$ make
|
||||
$ make check
|
||||
$ ./configure
|
||||
$ make
|
||||
$ make check
|
||||
|
||||
At this point, there should be no difference between your local copy,
|
||||
and the master copy:
|
||||
|
||||
$ git diff
|
||||
$ cvs diff
|
||||
|
||||
should output no difference.
|
||||
|
||||
Enjoy!
|
||||
|
||||
** Updating
|
||||
|
||||
The use of submodules make things somewhat different because git does
|
||||
not support recursive operations: submodules must be taken care of
|
||||
explicitly by the user.
|
||||
|
||||
*** Updating Bison
|
||||
|
||||
If you pull a newer version of a branch, say via "git pull", you might
|
||||
import requests for updated submodules. A simple "git diff" will
|
||||
reveal if the current version of the submodule (i.e., the actual
|
||||
contents of the gnulib directory) and the current request from the
|
||||
subscriber (i.e., the reference of the version of gnulib that the
|
||||
Bison repository requests) differ. To upgrade the submodules (i.e.,
|
||||
to check out the version that is actually requested by the subscriber,
|
||||
run "git submodule update".
|
||||
|
||||
$ git pull
|
||||
$ git submodule update
|
||||

*** Updating a submodule
|
||||
To update a submodule, say gnulib, do as follows:
|
||||
|
||||
Get the most recent version of the master branch from git.
|
||||
|
||||
$ cd gnulib
|
||||
$ git fetch
|
||||
$ git checkout -b master --track origin/master
|
||||
|
||||
Make sure Bison can live with that version of gnulib.
|
||||
|
||||
$ cd ..
|
||||
$ ./bootstrap
|
||||
$ make distcheck
|
||||
|
||||
Register your changes.
|
||||
|
||||
$ git checkin ...
|
||||
|
||||
For a suggestion of what gnulib commit might be stable enough for a
|
||||
formal release, see the ChangeLog in the latest gnulib snapshot at:
|
||||
|
||||
http://erislabs.net/ianb/projects/gnulib/
|
||||
|
||||
The Autoconf files we use are currently:
|
||||
|
||||
m4/m4.m4
|
||||
lib/m4sugar/m4sugar.m4
|
||||
lib/m4sugar/foreach.m4
|
||||
|
||||
These files don't change very often in Autoconf, so it should be
|
||||
relatively straight-forward to examine the differences in order to
|
||||
decide whether to update.
|
||||
|
||||
* Test suite
|
||||
|
||||
** make check
|
||||
Use liberally.
|
||||
|
||||
** Typical errors
|
||||
If the test suite shows failures such as the following one
|
||||
|
||||
.../bison/lib/getopt.h:196:8: error: redefinition of 'struct option'
|
||||
/usr/include/getopt.h:54:8: error: previous definition of 'struct option'
|
||||
|
||||
it probably means that some file was compiled without
|
||||
AT_DATA_SOURCE_PROLOGUE. This error is due to the fact that our -I options
|
||||
pick up gnulib's replacement headers, such as getopt.h, and this will go
|
||||
wrong if config.h was not included first.
|
||||
|
||||
See tests/local.at for details.
|
||||
|
||||
** make maintainer-check-valgrind
|
||||
This target uses valgrind both to check bison, and the generated parsers.
|
||||
|
||||
This is not mature on Mac OS X. First, Valgrind does support the way bison
|
||||
calls m4, so Valgrind cannot be used to check bison on Mac OS X.
|
||||
|
||||
Second, there are many errors that come from the platform itself, not from
|
||||
bison. build-aux/darwin11.4.0.valgrind addresses some of them.
|
||||
|
||||
Third, valgrind issues warnings such as:
|
||||
|
||||
--99312:0:syswrap- WARNING: Ignoring sigreturn( ..., UC_RESET_ALT_STACK );
|
||||
|
||||
which cause the test to fail uselessly. It is hard to ignore these errors
|
||||
with a major overhaul of the way instrumentation is performed in the test
|
||||
suite. So currently, do not try to run valgrind on Mac OS X.
|
||||
|
||||
** Release checks
|
||||
Try to run the test suite with more severe conditions before a
|
||||
release:
|
||||
|
||||
- Configure the package with --enable-gcc-warnings, so that one checks
|
||||
that 1. Bison compiles cleanly, 2. the parsers it produces compile
|
||||
cleanly too.
|
||||
|
||||
- Maybe build with -DGNULIB_POSIXCHECK, which suggests gnulib modules
|
||||
that can fix portability issues. See if you really want to pay
|
||||
attention to its warnings; there's no need to obey blindly to it
|
||||
(<http://lists.gnu.org/archive/html/bison-patches/2012-05/msg00057.html>).
|
||||
|
||||
- Check with "make syntax-check" if there are issues diagnosed by
|
||||
gnulib.
|
||||
|
||||
- run "make maintainer-check" which:
|
||||
- runs "valgrind -q bison" to run Bison under Valgrind.
|
||||
- runs the parsers under Valgrind.
|
||||
- runs the test suite with G++ as C compiler...
|
||||
|
||||
- run "make maintainer-push-check", which runs "make maintainer-check"
|
||||
while activating the push implementation and its pull interface wrappers
|
||||
in many test cases that were originally written to exercise only the
|
||||
pull implementation. This makes certain the push implementation can
|
||||
perform every task the pull implementation can.
|
||||
|
||||
- run "make maintainer-xml-check", which runs "make maintainer-check"
|
||||
while checking Bison's XML automaton report for every working grammar
|
||||
passed to Bison in the test suite. The check just diffs the output of
|
||||
Bison's included XSLT style sheets with the output of --report=all and
|
||||
--graph.
|
||||
|
||||
- running "make maintainer-release-check" takes care of running
|
||||
maintainer-check, maintainer-push-check and maintainer-xml-check.
|
||||
|
||||
- Change tests/atlocal/CFLAGS to add your preferred options. For
|
||||
instance, "-traditional" to check that the parsers are K&R. Note
|
||||
that it does not make sense for glr.c, which should be ANSI, but
|
||||
currently is actually GNU C, nor for lalr1.cc.
|
||||
|
||||
|
||||
* Release Procedure
|
||||
This section needs to be updated to take into account features from
|
||||
gnulib. In particular, be sure to read README-release.
|
||||
|
||||
** Update the submodules. See above.
|
||||
|
||||
** Update maintainer tools, such as Autoconf. See above.
|
||||
|
||||
** Try to get the *.pot files to the Translation Project at least one
|
||||
week before a stable release, to give them time to translate them.
|
||||
Before generating the *.pot files, make sure that po/POTFILES.in and
|
||||
runtime-po/POTFILES.in list all files with translatable strings.
|
||||
This helps: grep -l '\<_(' *
|
||||
|
||||
** Tests
|
||||
See above.
|
||||
|
||||
** Update the foreign files
|
||||
Running "./bootstrap" in the top level should update them all for you.
|
||||
This covers PO files too. Sometimes a PO file contains problems that
|
||||
causes it to be rejected by recent Gettext releases; please report
|
||||
these to the Translation Project.
|
||||
|
||||
** Update README
|
||||
Make sure the information in README is current. Most notably, make sure
|
||||
it recommends a version of GNU M4 that is compatible with the latest
|
||||
Bison sources.
|
||||
|
||||
** Check copyright years.
|
||||
We update years in copyright statements throughout Bison once at the
|
||||
start of every year by running "make update-copyright". However, before
|
||||
a release, it's good to verify that it's actually been run. Besides the
|
||||
copyright statement for each Bison file, check the copyright statements
|
||||
that the skeletons insert into generated parsers, and check all
|
||||
occurrences of PACKAGE_COPYRIGHT_YEAR in configure.ac.
|
||||
|
||||
** Update NEWS, commit and tag.
|
||||
See do-release-commit-and-tag in README-release. For a while, we used
|
||||
beta names such as "2.6_rc1". Now that we use gnulib in the release
|
||||
procedure, we must use "2.5.90", which has the additional benefit of
|
||||
being properly sorted in "git tag -l".
|
||||
|
||||
** make alpha, beta, or stable
|
||||
See README-release.
|
||||
|
||||
** Upload
|
||||
There are two ways to upload the tarballs to the GNU servers: using
|
||||
gnupload (from gnulib), or by hand. Obviously prefer the former. But
|
||||
in either case, be sure to read the following paragraph.
|
||||
|
||||
*** Setup
|
||||
You need "gnupg".
|
||||
|
||||
Make sure your public key has been uploaded at least to
|
||||
keys.gnupg.net. You can upload it with:
|
||||
|
||||
gpg --keyserver keys.gnupg.net --send-keys F125BDF3
|
||||
|
||||
where F125BDF3 should be replaced with your key ID.
|
||||
|
||||
*** Using gnupload
|
||||
You need "ncftp".
|
||||
|
||||
At the end "make stable" (or alpha/beta) will display the procedure to
|
||||
run. Just copy and paste it in your shell.
|
||||
|
||||
*** By hand
|
||||
|
||||
The generic GNU upload procedure is at:
|
||||
|
||||
http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads
|
||||
|
||||
Follow the instructions there to register your information so you're permitted
|
||||
to upload.
|
||||
|
||||
Here's a brief reminder of how to roll the tarballs and upload them:
|
||||
|
||||
*** make distcheck
|
||||
*** gpg -b bison-2.3b.tar.gz
|
||||
*** In a file named "bison-2.3b.tar.gz.directive", type:
|
||||
|
||||
version: 1.1
|
||||
directory: bison
|
||||
filename: bison-2.3b.tar.gz
|
||||
|
||||
*** gpg --clearsign bison-2.3b.tar.gz.directive
|
||||
*** ftp ftp-upload.gnu.org # Log in as anonymous.
|
||||
*** cd /incoming/alpha # cd /incoming/ftp for full release.
|
||||
*** put bison-2.3b.tar.gz # This can take a while.
|
||||
*** put bison-2.3b.tar.gz.sig
|
||||
*** put bison-2.3b.tar.gz.directive.asc
|
||||
*** Repeat all these steps for bison-2.3b.tar.xz.
|
||||
|
||||
** Update Bison manual on www.gnu.org.
|
||||
|
||||
*** You need a non-anonymous checkout of the web pages directory.
|
||||
|
||||
$ cvs -d [email protected]:/web/bison checkout bison
|
||||
|
||||
*** Get familiar with the instructions for web page maintainers.
|
||||
http://www.gnu.org/server/standards/readme_index.html
|
||||
http://www.gnu.org/server/standards/README.software.html
|
||||
especially the note about symlinks.
|
||||
|
||||
*** Build the web pages.
|
||||
Assuming BISON_CHECKOUT refers to a checkout of the Bison dir, and
|
||||
BISON_WWW_CHECKOUT refers to the web directory created above, do:
|
||||
|
||||
$ cd $BISON_CHECKOUT/doc
|
||||
$ make stamp-vti
|
||||
$ ../build-aux/gendocs.sh -o "$BISON_WWW_CHECKOUT/manual" \
|
||||
bison "Bison - GNU parser generator"
|
||||
$ cd $BISON_WWW_CHECKOUT
|
||||
|
||||
Verify that the result looks sane.
|
||||
|
||||
*** Commit the modified and the new files.
|
||||
|
||||
*** Remove old files.
|
||||
Find the files which have not been overwritten (because they belonged to
|
||||
sections that have been removed or renamed):
|
||||
|
||||
$ cd manual/html_node
|
||||
$ ls -lt
|
||||
|
||||
Remove these files and commit their removal to CVS. For each of these
|
||||
files, add a line to the file .symlinks. This will ensure that
|
||||
hyperlinks to the removed files will redirect to the entire manual; this
|
||||
is better than a 404 error.
|
||||
|
||||
There is a problem with 'index.html' being written twice (once for POSIX
|
||||
function 'index', once for the table of contents); you can ignore this
|
||||
issue.
|
||||
|
||||
** Announce
|
||||
The "make stable" (or alpha/beta) command just created a template,
|
||||
$HOME/announce-bison-X.Y. Otherwise, to generate it, run:
|
||||
|
||||
make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement
|
||||
|
||||
where alpha can be replaced by beta or stable and F125BDF3 should be
|
||||
replaced with your key ID.
|
||||
|
||||
Complete/fix the announcement file. The generated list of recipients
|
||||
([email protected], [email protected], [email protected],
|
||||
[email protected], and [email protected]) is
|
||||
appropriate for a stable release or a "serious beta". For any other
|
||||
release, drop at least [email protected]. For an example of how to
|
||||
fill out the rest of the template, search the mailing list archives
|
||||
for the most recent release announcement.
|
||||
|
||||
For a stable release, send the same announcement on the comp.compilers
|
||||
newsgroup by sending email to [email protected]. Do not make any Cc as
|
||||
the moderator will throw away anything cross-posted or Cc'ed. It really
|
||||
needs to be a separate message.
|
||||
|
||||
** Prepare NEWS
|
||||
So that developers don't accidentally add new items to the old NEWS
|
||||
entry, create a new empty entry in line 3 (without the two leading
|
||||
spaces):
|
||||
|
||||
* Noteworthy changes in release ?.? (????-??-??) [?]
|
||||
|
||||
Push these changes.

The code for the --graph option is over two files: print_graph, and

graphviz. I believe this is because Bison used to also produce VCG graphs,

** Discuss about %printer/%destroy in the case of C++.
|
||||
It would be very nice to provide the symbol classes with an operator<<
|
||||
and a destructor. Unfortunately the syntax we have chosen for
|
||||
%destroy and %printer make them hard to reuse. For instance, the user
|
||||
is invited to write something like
|
||||
* Yacc.c: CPP Macros
|
||||
|
||||
%printer { debug_stream() << $$; } <my_type>;
|
||||
|
||||
which is hard to reuse elsewhere since it wants to use
|
||||
"debug_stream()" to find the stream to use. The same applies to
|
||||
%destroy: we told the user she could use the members of the Parser
|
||||
class in the printers/destructors, which is not good for an operator<<
|
||||
since it is no longer bound to a particular parser, it's just a
|
||||
(standalone symbol).

||||
Warnings about type tags that are used in printer and dtors, but not

|
||||
|
||||
** YYERRCODE
|
||||
Defined to 256, but not used, not documented. Probably the token
|
||||
number for the error token, which POSIX wants to be 256, but which
|
||||
Bison might renumber if the user used number 256. Keep fix and doc?
|
||||
Throw away?
|
||||
|
||||
Also, why don't we output the token name of the error token in the
|
||||
output? It is explicitly skipped:
|
||||
|
||||
/* Skip error token and tokens without identifier. */
|
||||
if (sym != errtoken && id)
|
||||
|
||||
Of course there are issues with name spaces, but if we disable we have
|
||||
something which seems to be more simpler and more consistent instead
|
||||
of the special case YYERRCODE.
|

They should not: it is not documented. But if they need to, let's

|
||||
|
||||
|
||||
We could (should?) also treat the case of the undef_token, which is
|
||||
numbered 257 for yylex, and 2 internal. Both appear for instance in

toknum:

** YYFAIL
|
||||
It is seems to be *really* obsolete now, shall we remove it?
|
||||
|
||||
** yychar == yyempty_
|
||||
The code in yyerrlab reads:
|
||||
|
||||
if (yychar <= YYEOF)
|
||||
{
|
||||
/* Return failure if at end of input. */
|
||||
if (yychar == YYEOF)
|
||||
YYABORT;
|
||||
}
|
||||
|
||||
There are only two yychar that can be <= YYEOF: YYEMPTY and YYEOF.
|
||||
But I can't produce the situation where yychar is YYEMPTY here, is it
|
||||
really possible? The test suite does not exercise this case.
|
||||
|
||||
This shows that it would be interesting to manage to install skeleton
|
||||
coverage analysis to the test suite.
|
||||
|
||||
** Table definitions
|
||||
It should be very easy to factor the definition of the various tables,
|
||||
including the separation bw declaration and definition. See for
|
||||
instance b4_table_define in lalr1.cc. This way, we could even factor
|
||||
C vs. C++ definitions.
|
||||
|
||||
* From lalr1.cc to yacc.c
|
||||
** Single stack
|
||||
Merging the three stacks in lalr1.cc simplified the code, prompted for
|
||||
other improvements and also made it faster (probably because memory
|
||||
management is performed once instead of three times). I suggest that
|
||||
we do the same in yacc.c.
|

** Labeling the symbols

||||
Have a look at the Lemon parser generator: instead of $1, $2 etc. they

can name the values. This is much more pleasant. For instance:

||||
|
||||
exp (res): exp (a) '+' exp (b) { $res = $a + $b; };

symbol, and forgetting to shift all the $n to $n-1. If you are

unlucky, it compiles...
|

But instead of using $a etc., we can use regular variables. And

instead of using (), I propose to use `:' (again). Paul suggests

supporting `->' in addition to `:' to separate LHS and RHS. In other

words:

r:exp -> a:exp '+' b:exp { r = a + b; };

That requires an significant improvement of the grammar parser. Using

We already have an implementation that works fairly well for named

submessages from Bison. For example, the "previous definition"

location printed on the first line is not usually much shorter than the

locations printed on the submessage lines that follow. That assumption

may not hold true as often for some kinds of submessages especially if

* Skeletons
|

Bison skeletons: the general shapes of the different parser kinds,
|

that are specialized for specific grammars by the bison program.

Currently, the supported skeletons are:
|
||||
Currently, there are only three supported skeletons:
|
||||
|
||||
- yacc.c
|
||||
It used to be named bison.simple: it corresponds to C Yacc
|
||||
compatible LALR(1) parsers.
|
||||
|
||||
- lalr1.cc
|
||||
Produces a C++ parser class.
|
||||
|
||||
- lalr1.java
|
||||
Produces a Java parser class.
|
||||
Produces a C++ parser class. It is still very experimental, and not
|
||||
yet supported. Please, subscribe to [email protected].
|
||||
|
||||
- glr.c
|
||||
A Generalized LR C parser based on Bison's LALR(1) tables.
|
||||
|
||||
- glr.cc
|
||||
A Generalized LR C++ parser. Actually a C++ wrapper around glr.c.
|
||||
|
||||
These skeletons are the only ones supported by the Bison team.
|
||||
Because the interface between skeletons and the bison program is not
|
||||
finished, *we are not bound to it*. In particular, Bison is not
|
||||
mature enough for us to consider that ``foreign skeletons'' are
|
||||
supported.
|
||||
|
||||
* m4sugar
|
||||
This directory contains M4sugar, sort of an extended library for M4,
|
||||
which is used by Bison to instantiate the skeletons.
|
||||
|
||||
* xslt
|
||||
This directory contains XSLT programs that transform Bison's XML output
|
||||
into various formats.
|
||||
|
||||
- bison.xsl
|
||||
A library of routines used by the other XSLT programs.
|
||||
|
||||
- xml2dot.xsl
|
||||
Conversion into GraphViz's dot format.
|
||||
|
||||
- xml2text.xsl
|
||||
Conversion into text.
|
||||
|
||||
- xml2xhtml.xsl
|
||||
Conversion into XHTML.

the only way this function was invoked is if the default action

tokens because there are none.
|
||||
- The only way there can be no lookahead present (in yytoken) is
|
||||
if this state is a consistent state with a default action.
|
||||
Thus, detecting the absence of a lookahead is sufficient to
|
||||
determine that there is no unexpected or expected token to
|
||||
report. In that case, just report a simple "syntax error".
|
||||
- Don't assume there isn't a lookahead just because this state is
|
||||
a consistent state with a default action. There might have
|
||||
been a previous inconsistent state, consistent state with a
|
||||
non-default action, or user semantic action that manipulated
|
||||
yychar.
|
||||
- Of course, the expected token list depends on states to have
|
||||
correct lookahead information, and it depends on the parser not
|
||||
to perform extra reductions after fetching a lookahead from the
|
||||
scanner and before detecting a syntax error. Thus, state
|
||||
merging (from LALR or IELR) and default reductions corrupt the
|
||||
expected token list. However, the list is correct for
|
||||
canonical LR with one exception: it will still contain any
|
||||
token that will not be accepted due to an error action in a

later state.

See

<http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
|
||||
for details. YYERROR is fine as it does not invoke this
|
||||
function.
|
||||
- If this state is a consistent state with a default action,
|
||||
then the only way this function was invoked is if the
|
||||
default action is an error action. In that case, don't
|
||||
check for expected tokens because there are none.
|
||||
- The only way there can be no lookahead present (in tok) is
|
||||
if this state is a consistent state with a default action.
|
||||
Thus, detecting the absence of a lookahead is sufficient to
|
||||
determine that there is no unexpected or expected token to
|
||||
report. In that case, just report a simple "syntax error".
|
||||
- Don't assume there isn't a lookahead just because this
|
||||
state is a consistent state with a default action. There
|
||||
might have been a previous inconsistent state, consistent
|
||||
state with a non-default action, or user semantic action
|
||||
that manipulated yychar. (However, yychar is currently out
|
||||
of scope during semantic actions.)
|
||||
- Of course, the expected token list depends on states to
|
||||
have correct lookahead information, and it depends on the
|
||||
parser not to perform extra reductions after fetching a
|
||||
lookahead from the scanner and before detecting a syntax
|
||||
error. Thus, state merging (from LALR or IELR) and default
|
||||
reductions corrupt the expected token list. However, the
|
||||
list is correct for canonical LR with one exception: it
|
||||
will still contain any token that will not be accepted due
|
||||
to an error action in a later state.

.TH BISON "1" "March 2008" "bison 2.3a+" "User Commands"
|
||||
.SH NAME
|
||||
bison \- GNU Project parser generator (yacc replacement)
|
||||
.SH SYNOPSIS
|
||||
.B bison
|
||||
[\fIOPTION\fR]... \fIFILE\fR
|
||||
.SH DESCRIPTION
|
||||
.I Bison
|
||||
is a parser generator in the style of
|
||||
.IR yacc (1).
|
||||
It should be upwardly compatible with input files designed
|
||||
for
|
||||
.IR yacc .
|
||||
.PP
|
||||
Input files should follow the
|
||||
.I yacc
|
||||
convention of ending in
|
||||
.BR .y .
|
||||
Unlike
|
||||
.IR yacc ,
|
||||
the generated files do not have fixed names, but instead use the prefix
|
||||
of the input file.
|
||||
Moreover, if you need to put
|
||||
.I C++
|
||||
code in the input file, you can end his name by a C++-like extension
|
||||
(.ypp or .y++), then bison will follow your extension to name the
|
||||
output file (.cpp or .c++).
|
||||
For instance, a grammar description file named
|
||||
.B parse.yxx
|
||||
would produce the generated parser in a file named
|
||||
.BR parse.tab.cxx ,
|
||||
instead of
|
||||
.IR yacc 's
|
||||
.B y.tab.c
|
||||
or old
|
||||
.I Bison
|
||||
version's
|
||||
.BR parse.tab.c .
|
||||
.PP
|
||||
This description of the options that can be given to
|
||||
.I bison
|
||||
is adapted from the node
|
||||
.B Invocation
|
||||
in the
|
||||
.B bison.texinfo
|
||||
manual, which should be taken as authoritative.
|
||||
.PP
|
||||
.I Bison
|
||||
supports both traditional single-letter options and mnemonic long
|
||||
option names. Long option names are indicated with
|
||||
.B \-\-
|
||||
instead of
|
||||
.BR \- .
|
||||
Abbreviations for option names are allowed as long as they
|
||||
are unique. When a long option takes an argument, like
|
||||
.BR \-\-file-prefix ,
|
||||
connect the option name and the argument with
|
||||
.BR = .
|
||||
.PP
|
||||
Generate LALR(1) and GLR parsers.
|
||||
.PP
|
||||
Mandatory arguments to long options are mandatory for short options too.
|
||||
The same is true for optional arguments.

PREAMBLE
|
||||
|
||||
The purpose of this License is to make a manual, textbook, or other
|
||||
functional and useful document @dfn{free} in the sense of freedom: to
|
||||
assure everyone the effective freedom to copy and redistribute it,
|
||||
with or without modifying it, either commercially or noncommercially.
|
||||
Secondarily, this License preserves for the author and publisher a way
|
||||
to get credit for their work, while not being considered responsible
|
||||
for modifications made by others.
|
||||
|
||||
This License is a kind of ``copyleft'', which means that derivative
|
||||
works of the document must themselves be free in the same sense. It
|
||||
complements the GNU General Public License, which is a copyleft
|
||||
license designed for free software.
|
||||
|
||||
We have designed this License in order to use it for manuals for free
|
||||
software, because free software needs free documentation: a free
|
||||
program should come with manuals providing the same freedoms that the
|
||||
software does. But this License is not limited to software manuals;
|
||||
it can be used for any textual work, regardless of subject matter or
|
||||
whether it is published as a printed book. We recommend this License
|
||||
principally for works whose purpose is instruction or reference.
|
||||
|
||||
@item
|
||||
APPLICABILITY AND DEFINITIONS
|
||||
|
||||
This License applies to any manual or other work, in any medium, that
|
||||
contains a notice placed by the copyright holder saying it can be
|
||||
distributed under the terms of this License. Such a notice grants a
|
||||
world-wide, royalty-free license, unlimited in duration, to use that
|
||||
work under the conditions stated herein. The ``Document'', below,
|
||||
refers to any such manual or work. Any member of the public is a
|
||||
licensee, and is addressed as ``you''. You accept the license if you
|
||||
copy, modify or distribute the work in a way requiring permission
|
||||
under copyright law.
|
||||
|
||||
A ``Modified Version'' of the Document means any work containing the
|
||||
Document or a portion of it, either copied verbatim, or with
|
||||
modifications and/or translated into another language.
|
||||
|
||||
A ``Secondary Section'' is a named appendix or a front-matter section
|
||||
of the Document that deals exclusively with the relationship of the
|
||||
publishers or authors of the Document to the Document's overall
|
||||
subject (or to related matters) and contains nothing that could fall
|
||||
directly within that overall subject. (Thus, if the Document is in
|
||||
part a textbook of mathematics, a Secondary Section may not explain
|
||||
any mathematics.) The relationship could be a matter of historical
|
||||
connection with the subject or with related matters, or of legal,
|
||||
commercial, philosophical, ethical or political position regarding
|
||||
them.
|
||||
|
||||
The ``Invariant Sections'' are certain Secondary Sections whose titles
|
||||
are designated, as being those of Invariant Sections, in the notice
|
||||
that says that the Document is released under this License. If a
|
||||
section does not fit the above definition of Secondary then it is not
|
||||
allowed to be designated as Invariant. The Document may contain zero
|
||||
Invariant Sections. If the Document does not identify any Invariant
|
||||
Sections then there are none.
|
||||
|
||||
The ``Cover Texts'' are certain short passages of text that are listed,
|
||||
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
|
||||
the Document is released under this License. A Front-Cover Text may
|
||||
be at most 5 words, and a Back-Cover Text may be at most 25 words.
|
||||
|
||||
A ``Transparent'' copy of the Document means a machine-readable copy,
|
||||
represented in a format whose specification is available to the
|
||||
general public, that is suitable for revising the document
|
||||
straightforwardly with generic text editors or (for images composed of
|
||||
pixels) generic paint programs or (for drawings) some widely available
|
||||
drawing editor, and that is suitable for input to text formatters or
|
||||
for automatic translation to a variety of formats suitable for input
|
||||
to text formatters. A copy made in an otherwise Transparent file
|
||||
format whose markup, or absence of markup, has been arranged to thwart
|
||||
or discourage subsequent modification by readers is not Transparent.
|
||||
An image format is not Transparent if used for any substantial amount
|
||||
of text. A copy that is not ``Transparent'' is called ``Opaque''.
|
||||
|
||||
Examples of suitable formats for Transparent copies include plain
|
||||
@sc{ascii} without markup, Texinfo input format, La@TeX{} input
|
||||
format, @acronym{SGML} or @acronym{XML} using a publicly available
|
||||
@acronym{DTD}, and standard-conforming simple @acronym{HTML},
|
||||
PostScript or @acronym{PDF} designed for human modification. Examples
|
||||
of transparent image formats include @acronym{PNG}, @acronym{XCF} and
|
||||
@acronym{JPG}. Opaque formats include proprietary formats that can be
|
||||
read and edited only by proprietary word processors, @acronym{SGML} or
|
||||
@acronym{XML} for which the @acronym{DTD} and/or processing tools are
|
||||
not generally available, and the machine-generated @acronym{HTML},
|
||||
PostScript or @acronym{PDF} produced by some word processors for
|
||||
output purposes only.
|
||||
|
||||
The ``Title Page'' means, for a printed book, the title page itself,
|
||||
plus such following pages as are needed to hold, legibly, the material
|
||||
this License requires to appear in the title page. For works in
|
||||
formats which do not have any title page as such, ``Title Page'' means
|
||||
the text near the most prominent appearance of the work's title,
|
||||
preceding the beginning of the body of the text.
|
||||
|
||||
A section ``Entitled XYZ'' means a named subunit of the Document whose
|
||||
title either is precisely XYZ or contains XYZ in parentheses following
|
||||
text that translates XYZ in another language. (Here XYZ stands for a
|
||||
specific section name mentioned below, such as ``Acknowledgements'',
|
||||
``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
|
||||
of such a section when you modify the Document means that it remains a
|
||||
section ``Entitled XYZ'' according to this definition.
|
||||
|
||||
The Document may include Warranty Disclaimers next to the notice which
|
||||
states that this License applies to the Document. These Warranty
|
||||
Disclaimers are considered to be included by reference in this
|
||||
License, but only as regards disclaiming warranties: any other
|
||||
implication that these Warranty Disclaimers may have is void and has
|
||||
no effect on the meaning of this License.
|
||||
|
||||
@item
|
||||
VERBATIM COPYING
|
||||
|
||||
You may copy and distribute the Document in any medium, either
|
||||
commercially or noncommercially, provided that this License, the
|
||||
copyright notices, and the license notice saying this License applies
|
||||
to the Document are reproduced in all copies, and that you add no other
|
||||
conditions whatsoever to those of this License. You may not use
|
||||
technical measures to obstruct or control the reading or further
|
||||
copying of the copies you make or distribute. However, you may accept
|
||||
compensation in exchange for copies. If you distribute a large enough
|
||||
number of copies you must also follow the conditions in section 3.
|
||||
|
||||
You may also lend copies, under the same conditions stated above, and
|
||||
you may publicly display copies.
|
||||
|
||||
@item
|
||||
COPYING IN QUANTITY
|
||||
|
||||
If you publish printed copies (or copies in media that commonly have
|
||||
printed covers) of the Document, numbering more than 100, and the
|
||||
Document's license notice requires Cover Texts, you must enclose the
|
||||
copies in covers that carry, clearly and legibly, all these Cover
|
||||
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
|
||||
the back cover. Both covers must also clearly and legibly identify
|
||||
you as the publisher of these copies. The front cover must present
|
||||
the full title with all words of the title equally prominent and
|
||||
visible. You may add other material on the covers in addition.
|
||||
Copying with changes limited to the covers, as long as they preserve
|
||||
the title of the Document and satisfy these conditions, can be treated
|
||||
as verbatim copying in other respects.
|
||||
|
||||
If the required texts for either cover are too voluminous to fit
|
||||
legibly, you should put the first ones listed (as many as fit
|
||||
reasonably) on the actual cover, and continue the rest onto adjacent
|
||||
pages.
|
||||
|
||||
If you publish or distribute Opaque copies of the Document numbering
|
||||
more than 100, you must either include a machine-readable Transparent
|
||||
copy along with each Opaque copy, or state in or with each Opaque copy
|
||||
a computer-network location from which the general network-using
|
||||
public has access to download using public-standard network protocols
|
||||
a complete Transparent copy of the Document, free of added material.
|
||||
If you use the latter option, you must take reasonably prudent steps,
|
||||
when you begin distribution of Opaque copies in quantity, to ensure
|
||||
that this Transparent copy will remain thus accessible at the stated
|
||||
location until at least one year after the last time you distribute an
|
||||
Opaque copy (directly or through your agents or retailers) of that
|
||||
edition to the public.
|
||||
|
||||
It is requested, but not required, that you contact the authors of the
|
||||
Document well before redistributing any large number of copies, to give
|
||||
them a chance to provide you with an updated version of the Document.

the conditions of sections 2 and 3 above, provided that you release
|
||||
the Modified Version under precisely this License, with the Modified
|
||||
Version filling the role of the Document, thus licensing distribution
|
||||
and modification of the Modified Version to whoever possesses a copy
|
||||
of it. In addition, you must do these things in the Modified Version:
|
||||
|
||||
@enumerate A
|
||||
@item
|
||||
Use in the Title Page (and on the covers, if any) a title distinct
|
||||
from that of the Document, and from those of previous versions
|
||||
(which should, if there were any, be listed in the History section
|
||||
of the Document). You may use the same title as a previous version
|
||||
if the original publisher of that version gives permission.
|
||||
|
||||
@item
|
||||
List on the Title Page, as authors, one or more persons or entities
|
||||
responsible for authorship of the modifications in the Modified
|
||||
Version, together with at least five of the principal authors of the
|
||||
Document (all of its principal authors, if it has fewer than five),
|
||||
unless they release you from this requirement.
|
||||
|
||||
@item
|
||||
State on the Title page the name of the publisher of the
|
||||
Modified Version, as the publisher.
|
||||
|
||||
@item
|
||||
Preserve all the copyright notices of the Document.
|
||||
|
||||
@item
|
||||
Add an appropriate copyright notice for your modifications
|
||||
adjacent to the other copyright notices.
|
||||
|
||||
@item
|
||||
Include, immediately after the copyright notices, a license notice
|
||||
giving the public permission to use the Modified Version under the
|
||||
terms of this License, in the form shown in the Addendum below.
|
||||
|
||||
@item
|
||||
Preserve in that license notice the full lists of Invariant Sections
|
||||
and required Cover Texts given in the Document's license notice.
|
||||
|
||||
@item
|
||||
Include an unaltered copy of this License.
|
||||
|
||||
@item
|
||||
Preserve the section Entitled ``History'', Preserve its Title, and add
|
||||
to it an item stating at least the title, year, new authors, and
|
||||
publisher of the Modified Version as given on the Title Page. If
|
||||
there is no section Entitled ``History'' in the Document, create one
|
||||
stating the title, year, authors, and publisher of the Document as
|
||||
given on its Title Page, then add an item describing the Modified
|
||||
Version as stated in the previous sentence.
|
||||
|
||||
@item
|
||||
Preserve the network location, if any, given in the Document for
|
||||
public access to a Transparent copy of the Document, and likewise
|
||||
the network locations given in the Document for previous versions
|
||||
it was based on. These may be placed in the ``History'' section.
|
||||
You may omit a network location for a work that was published at
|
||||
least four years before the Document itself, or if the original
|
||||
publisher of the version it refers to gives permission.
|
||||
|
||||
@item
|
||||
For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
|
||||
the Title of the section, and preserve in the section all the
|
||||
substance and tone of each of the contributor acknowledgements and/or
|
||||
dedications given therein.
|
||||
|
||||
@item
|
||||
Preserve all the Invariant Sections of the Document,
|
||||
unaltered in their text and in their titles. Section numbers
|
||||
or the equivalent are not considered part of the section titles.
|
||||
|
||||
@item
|
||||
Delete any section Entitled ``Endorsements''. Such a section
|
||||
may not be included in the Modified Version.
|
||||
|
||||
@item
|
||||
Do not retitle any existing section to be Entitled ``Endorsements'' or
|
||||
to conflict in title with any Invariant Section.
|
||||
|
||||
@item
|
||||
Preserve any Warranty Disclaimers.
|
||||
@end enumerate
|
||||
|
||||
If the Modified Version includes new front-matter sections or
|
||||
appendices that qualify as Secondary Sections and contain no material
|
||||
copied from the Document, you may at your option designate some or all
|
||||
of these sections as invariant. To do this, add their titles to the
|
||||
list of Invariant Sections in the Modified Version's license notice.
|
||||
These titles must be distinct from any other section titles.
|
||||
|
||||
You may add a section Entitled ``Endorsements'', provided it contains
|
||||
nothing but endorsements of your Modified Version by various
|
||||
parties---for example, statements of peer review or that the text has
|
||||
been approved by an organization as the authoritative definition of a
|
||||
standard.
|
||||
|
||||
You may add a passage of up to five words as a Front-Cover Text, and a
|
||||
passage of up to 25 words as a Back-Cover Text, to the end of the list
|
||||
of Cover Texts in the Modified Version. Only one passage of
|
||||
Front-Cover Text and one of Back-Cover Text may be added by (or
|
||||
through arrangements made by) any one entity. If the Document already
|
||||
includes a cover text for the same cover, previously added by you or
|
||||
by arrangement made by the same entity you are acting on behalf of,
|
||||
you may not add another; but you may replace the old one, on explicit
|
||||
permission from the previous publisher that added the old one.
|
||||
|
||||
The author(s) and publisher(s) of the Document do not by this License
|
||||
give permission to use their names for publicity for or to assert or
|
||||
imply endorsement of any Modified Version.
|
||||
|
||||
@item
|
||||
COMBINING DOCUMENTS
|
||||
|
||||
You may combine the Document with other documents released under this
|
||||
License, under the terms defined in section 4 above for modified
|
||||
versions, provided that you include in the combination all of the
|
||||
Invariant Sections of all of the original documents, unmodified, and
|
||||
list them all as Invariant Sections of your combined work in its
|
||||
license notice, and that you preserve all their Warranty Disclaimers.
|
||||
|
||||
The combined work need only contain one copy of this License, and
|
||||
multiple identical Invariant Sections may be replaced with a single
|
||||
copy. If there are multiple Invariant Sections with the same name but
|
||||
different contents, make the title of each such section unique by
|
||||
adding at the end of it, in parentheses, the name of the original
|
||||
author or publisher of that section if known, or else a unique number.
|
||||
Make the same adjustment to the section titles in the list of
|
||||
Invariant Sections in the license notice of the combined work.
|
||||
|
||||
In the combination, you must combine any sections Entitled ``History''
|
||||
in the various original documents, forming one section Entitled
|
||||
``History''; likewise combine any sections Entitled ``Acknowledgements'',
|
||||
and any sections Entitled ``Dedications''. You must delete all
|
||||
sections Entitled ``Endorsements.''
|
||||
|
||||
@item
|
||||
COLLECTIONS OF DOCUMENTS
|
||||
|
||||
You may make a collection consisting of the Document and other documents
|
||||
released under this License, and replace the individual copies of this
|
||||
License in the various documents with a single copy that is included in
|
||||
the collection, provided that you follow the rules of this License for
|
||||
verbatim copying of each of the documents in all other respects.
|
||||
|
||||
You may extract a single document from such a collection, and distribute
|
||||
it individually under this License, provided you insert a copy of this
|
||||
License into the extracted document, and follow this License in all
|
||||
other respects regarding verbatim copying of that document.
|
||||
|
||||
@item
|
||||
AGGREGATION WITH INDEPENDENT WORKS
|
||||
|
||||
A compilation of the Document or its derivatives with other separate
|
||||
and independent documents or works, in or on a volume of a storage or
|
||||
distribution medium, is called an ``aggregate'' if the copyright
|
||||
resulting from the compilation is not used to limit the legal rights
|
||||
of the compilation's users beyond what the individual works permit.
|
||||
When the Document is included in an aggregate, this License does not
|
||||
apply to the other works in the aggregate which are not themselves
|
||||
derivative works of the Document.
|
||||
|
||||
If the Cover Text requirement of section 3 is applicable to these
|
||||
copies of the Document, then if the Document is less than one half of
|
||||
the entire aggregate, the Document's Cover Texts may be placed on
|
||||
covers that bracket the Document within the aggregate, or the
|
||||
electronic equivalent of covers if the Document is in electronic form.
|
||||
Otherwise they must appear on printed covers that bracket the whole
|
||||
aggregate.
|
||||
|
||||
@item
|
||||
TRANSLATION
|
||||
|
||||
Translation is considered a kind of modification, so you may
|
||||
distribute translations of the Document under the terms of section 4.
|
||||
Replacing Invariant Sections with translations requires special
|
||||
permission from their copyright holders, but you may include
|
||||
translations of some or all Invariant Sections in addition to the
|
||||
original versions of these Invariant Sections. You may include a
|
||||
translation of this License, and all the license notices in the
|
||||
Document, and any Warranty Disclaimers, provided that you also include
|
||||
the original English version of this License and the original versions
|
||||
of those notices and disclaimers. In case of a disagreement between
|
||||
the translation and the original version of this License or a notice
|
||||
or disclaimer, the original version will prevail.
|
||||
|
||||
If a section in the Document is Entitled ``Acknowledgements'',
|
||||
``Dedications'', or ``History'', the requirement (section 4) to Preserve
|
||||
its Title (section 1) will typically require changing the actual
|
||||
title.
|
||||
|
||||
@item
|
||||
TERMINATION
|
||||
|
||||
You may not copy, modify, sublicense, or distribute the Document except
|
||||
as expressly provided for under this License. Any other attempt to
|
||||
copy, modify, sublicense or distribute the Document is void, and will
|
||||
automatically terminate your rights under this License. However,
|
||||
parties who have received copies, or rights, from you under this
|
||||
License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
@item
|
||||
FUTURE REVISIONS OF THIS LICENSE
|
||||
|
||||
The Free Software Foundation may publish new, revised versions
|
||||
of the GNU Free Documentation License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns. See
|
||||
@uref{http://www.gnu.org/copyleft/}.
|
||||
|
||||
Each version of the License is given a distinguishing version number.
|
||||
If the Document specifies that a particular numbered version of this
|
||||
License ``or any later version'' applies to it, you have the option of
|
||||
following the terms and conditions either of that specified version or
|
||||
of any later version that has been published (not as a draft) by the
|
||||
Free Software Foundation. If the Document does not specify a version
|
||||
number of this License, you may choose any version ever published (not
|
||||
as a draft) by the Free Software Foundation.

@heading Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom
|
||||
to share and change all versions of a program---to make sure it remains
|
||||
free software for all its users. We, the Free Software Foundation,
|
||||
use the GNU General Public License for most of our software; it
|
||||
applies also to any other work released this way by its authors. You
|
||||
can apply it to your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you
|
||||
have certain responsibilities if you distribute copies of the
|
||||
software, or if you modify it: responsibilities to respect the freedom
|
||||
of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too,
|
||||
receive or can get the source code. And you must show them these
|
||||
terms so they know their rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the
|
||||
manufacturer can do so. This is fundamentally incompatible with the
|
||||
aim of protecting users' freedom to change the software. The
|
||||
systematic pattern of such abuse occurs in the area of products for
|
||||
individuals to use, which is precisely where it is most unacceptable.
|
||||
Therefore, we have designed this version of the GPL to prohibit the
|
||||
practice for those products. If such problems arise substantially in
|
||||
other domains, we stand ready to extend this provision to those
|
||||
domains in future versions of the GPL, as needed to protect the
|
||||
freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish
|
||||
to avoid the special danger that patents applied to a free program
|
||||
could make it effectively proprietary. To prevent this, the GPL
|
||||
assures that patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.

|
||||
|
||||
``This License'' refers to version 3 of the GNU General Public License.
|
||||
|
||||
``Copyright'' also means copyright-like laws that apply to other kinds
|
||||
of works, such as semiconductor masks.
|
||||
|
||||
``The Program'' refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as ``you''. ``Licensees'' and
|
||||
``recipients'' may be individuals or organizations.
|
||||
|
||||
To ``modify'' a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of
|
||||
an exact copy. The resulting work is called a ``modified version'' of
|
||||
the earlier work or a work ``based on'' the earlier work.
|
||||
|
||||
A ``covered work'' means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To ``propagate'' a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To ``convey'' a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user
|
||||
through a computer network, with no transfer of a copy, is not
|
||||
conveying.
|
||||
|
||||
An interactive user interface displays ``Appropriate Legal Notices'' to
|
||||
the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
@item Source Code.
|
||||
|
||||
The ``source code'' for a work means the preferred form of the work for
|
||||
making modifications to it. ``Object code'' means any non-source form
|
||||
of a work.
|
||||
|
||||
A ``Standard Interface'' means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The ``System Libraries'' of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
``Major Component'', in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The ``Corresponding Source'' for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users can
|
||||
regenerate automatically from other parts of the Corresponding Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that same
|
||||
work.
|
||||
|
||||
@item Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not convey,
|
||||
without conditions so long as your license otherwise remains in force.
|
||||
You may convey covered works to others for the sole purpose of having
|
||||
them make modifications exclusively for you, or provide you with
|
||||
facilities for running those works, provided that you comply with the
|
||||
terms of this License in conveying all material for which you do not
|
||||
control copyright. Those thus making or running the covered works for
|
||||
you must do so exclusively on your behalf, under your direction and
|
||||
control, on terms that prohibit them from making any copies of your
|
||||
copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under the
|
||||
conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
@item Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such
|
||||
circumvention is effected by exercising rights under this License with
|
||||
respect to the covered work, and you disclaim any intention to limit
|
||||
operation or modification of the work as a means of enforcing, against
|
||||
the work's users, your or third parties' legal rights to forbid
|
||||
circumvention of technological measures.
|
||||
|
||||
@item Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
@item Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these
|
||||
conditions:
|
||||
|
||||
@enumerate a
|
||||
@item
|
||||
The work must carry prominent notices stating that you modified it,
|
||||
and giving a relevant date.
|
||||
|
||||
@item
|
||||
The work must carry prominent notices stating that it is released
|
||||
under this License and any conditions added under section 7. This
|
||||
requirement modifies the requirement in section 4 to ``keep intact all
|
||||
notices''.
|
||||
|
||||
@item
|
||||
You must license the entire work, as a whole, under this License to
|
||||
anyone who comes into possession of a copy. This License will
|
||||
therefore apply, along with any applicable section 7 additional terms,
|
||||
to the whole of the work, and all its parts, regardless of how they
|
||||
are packaged. This License gives no permission to license the work in
|
||||
any other way, but it does not invalidate such permission if you have
|
||||
separately received it.
|
||||
|
||||
@item
|
||||
If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your work
|
||||
need not make them do so.
|
||||
@end enumerate
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
``aggregate'' if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
@item Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms of
|
||||
sections 4 and 5, provided that you also convey the machine-readable
|
||||
Corresponding Source under the terms of this License, in one of these
|
||||
ways:
|
||||
|
||||
@enumerate a
|
||||
@item
|
||||
Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium customarily
|
||||
used for software interchange.
|
||||
|
||||
@item
|
||||
Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a written
|
||||
offer, valid for at least three years and valid for as long as you
|
||||
offer spare parts or customer support for that product model, to give
|
||||
anyone who possesses the object code either (1) a copy of the
|
||||
Corresponding Source for all the software in the product that is
|
||||
covered by this License, on a durable physical medium customarily used
|
||||
for software interchange, for a price no more than your reasonable
|
||||
cost of physically performing this conveying of source, or (2) access
|
||||
to copy the Corresponding Source from a network server at no charge.
|
||||
|
||||
@item
|
||||
Convey individual copies of the object code with a copy of the written
|
||||
offer to provide the Corresponding Source. This alternative is
|
||||
allowed only occasionally and noncommercially, and only if you
|
||||
received the object code with such an offer, in accord with subsection
|
||||
6b.
|
||||
|
||||
@item
|
||||
Convey the object code by offering access from a designated place
|
||||
(gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to copy
|
||||
the object code is a network server, the Corresponding Source may be
|
||||
on a different server (operated by you or a third party) that supports
|
||||
equivalent copying facilities, provided you maintain clear directions
|
||||
next to the object code saying where to find the Corresponding Source.
|
||||
Regardless of what server hosts the Corresponding Source, you remain
|
||||
obligated to ensure that it is available for as long as needed to
|
||||
satisfy these requirements.
|
||||
|
||||
@item
|
||||
Convey the object code using peer-to-peer transmission, provided you
|
||||
inform other peers where the object code and Corresponding Source of
|
||||
the work are being offered to the general public at no charge under
|
||||
subsection 6d.
|
||||
|
||||
@end enumerate
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A ``User Product'' is either (1) a ``consumer product'', which means any
|
||||
tangible personal property which is normally used for personal,
|
||||
family, or household purposes, or (2) anything designed or sold for
|
||||
incorporation into a dwelling. In determining whether a product is a
|
||||
consumer product, doubtful cases shall be resolved in favor of
|
||||
coverage. For a particular product received by a particular user,
|
||||
``normally used'' refers to a typical or common use of that class of
|
||||
product, regardless of the status of the particular user or of the way
|
||||
in which the particular user actually uses, or expects or is expected
|
||||
to use, the product. A product is a consumer product regardless of
|
||||
whether the product has substantial commercial, industrial or
|
||||
non-consumer uses, unless such uses represent the only significant
|
||||
mode of use of the product.
|
||||
|
||||
``Installation Information'' for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to
|
||||
install and execute modified versions of a covered work in that User
|
||||
Product from a modified version of its Corresponding Source. The
|
||||
information must suffice to ensure that the continued functioning of
|
||||
the modified object code is in no case prevented or interfered with
|
||||
solely because modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or
|
||||
updates for a work that has been modified or installed by the
|
||||
recipient, or for the User Product in which it has been modified or
|
||||
installed. Access to a network may be denied when the modification
|
||||
itself materially and adversely affects the operation of the network
|
||||
or violates the rules and protocols for communication across the
|
||||
network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
@item Additional Terms.
|
||||
|
||||
``Additional permissions'' are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders
|
||||
of that material) supplement the terms of this License with terms:
|
||||
|
||||
@enumerate a
|
||||
@item
|
||||
Disclaiming warranty or limiting liability differently from the terms
|
||||
of sections 15 and 16 of this License; or
|
||||
|
||||
@item
|
||||
Requiring preservation of specified reasonable legal notices or author
|
||||
attributions in that material or in the Appropriate Legal Notices
|
||||
displayed by works containing it; or
|
||||
|
||||
@item
|
||||
Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
@item
|
||||
Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
@item
|
||||
Declining to grant rights under trademark law for use of some trade
|
||||
names, trademarks, or service marks; or
|
||||
|
||||
@item
|
||||
Requiring indemnification of licensors and authors of that material by
|
||||
anyone who conveys the material (or modified versions of it) with
|
||||
contractual assumptions of liability to the recipient, for any
|
||||
liability that these contractual assumptions directly impose on those
|
||||
licensors and authors.
|
||||
@end enumerate
|
||||
|
||||
All other non-permissive additional terms are considered ``further
|
||||
restrictions'' within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions; the
|
||||
above requirements apply either way.
|
||||
|
||||
@item Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your license
|
||||
from a particular copyright holder is reinstated (a) provisionally,
|
||||
unless and until the copyright holder explicitly and finally
|
||||
terminates your license, and (b) permanently, if the copyright holder
|
||||
fails to notify you of the violation by some reasonable means prior to
|
||||
60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
@item Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or run
|
||||
a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
@item Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An ``entity transaction'' is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
@item Patents.
|
||||
|
||||
A ``contributor'' is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's ``contributor version''.
|
||||
|
||||
A contributor's ``essential patent claims'' are all patent claims owned
|
||||
or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, ``control'' includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a ``patent license'' is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To ``grant'' such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. ``Knowingly relying'' means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is ``discriminatory'' if it does not include within the
|
||||
scope of its coverage, prohibits the exercise of, or is conditioned on
|
||||
the non-exercise of one or more of the rights that are specifically
|
||||
granted under this License. You may not convey a covered work if you
|
||||
are a party to an arrangement with a third party that is in the
|
||||
business of distributing software, under which you make payment to the
|
||||
third party based on the extent of your activity of conveying the
|
||||
work, and under which the third party grants, to any of the parties
|
||||
who would receive the covered work from you, a discriminatory patent
|
||||
license (a) in connection with copies of the covered work conveyed by
|
||||
you (or copies made from those copies), or (b) primarily for and in
|
||||
connection with specific products or compilations that contain the
|
||||
covered work, unless you entered into that arrangement, or that patent
|
||||
license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
@item No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey
|
||||
a covered work so as to satisfy simultaneously your obligations under
|
||||
this License and any other pertinent obligations, then as a
|
||||
consequence you may not convey it at all. For example, if you agree
|
||||
to terms that obligate you to collect a royalty for further conveying
|
||||
from those to whom you convey the Program, the only way you could
|
||||
satisfy both those terms and this License would be to refrain entirely
|
||||
from conveying the Program.
|
||||
|
||||
@item Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
@item Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU General Public License from time to time. Such new
|
||||
versions will be similar in spirit to the present version, but may
|
||||
differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies that a certain numbered version of the GNU General Public
|
||||
License ``or any later version'' applies to it, you have the option of
|
||||
following the terms and conditions either of that numbered version or
|
||||
of any later version published by the Free Software Foundation. If
|
||||
the Program does not specify a version number of the GNU General
|
||||
Public License, you may choose any version ever published by the Free
|
||||
Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future versions
|
||||
of the GNU General Public License can be used, that proxy's public
|
||||
statement of acceptance of a version permanently authorizes you to
|
||||
choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
@item Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
|
||||
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
|
||||
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
|
||||
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
|
||||
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
|
||||
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
|
||||
CORRECTION.
|
||||
|
||||
@item Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
|
||||
CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
|
||||
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
|
||||
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
|
||||
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
|
||||
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
|
||||
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
@item Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
@end enumerate
|
||||
|
||||
@heading END OF TERMS AND CONDITIONS
|
||||
|
||||
@heading How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these
|
||||
terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
state the exclusion of warranty; and each file should have at least
|
||||
the ``copyright'' line and a pointer to where the full notice is found.
|
||||
|
||||

||||

This program is free software: you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License as published by
|
||||
the Free Software Foundation, either version 3 of the License, or (at
|
||||
your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful, but
|
||||
WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||
General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program. If not, see @url{http://www.gnu.org/licenses/}.
|
||||
@end smallexample
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
@smallexample
|
||||
@var{program} Copyright (C) @var{year} @var{name of author}
|
||||
This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type @samp{show c} for details.
|
||||
@end smallexample
|
||||
|
||||
The hypothetical commands @samp{show w} and @samp{show c} should show
|
||||
the appropriate parts of the General Public License. Of course, your
|
||||
program's commands might be different; for a GUI interface, you would
|
||||
use an ``about box''.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a ``copyright disclaimer'' for the program, if necessary.
|
||||
For more information on this, and how to apply and follow the GNU GPL, see
|
||||
@url{http://www.gnu.org/licenses/}.
|
||||
|
||||
The GNU General Public License does not permit incorporating your
|
||||
program into proprietary programs. If your program is a subroutine
|
||||
library, you may consider it more useful to permit linking proprietary
|
||||
applications with the library. If this is what you want to do, use
|
||||
the GNU Lesser General Public License instead of this License. But
|
||||
first, please read @url{http://www.gnu.org/philosophy/why-not-lgpl.html}.
