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.

|

* Installation
|
||||
** Build
|
||||
See the file INSTALL for generic compilation and installation instructions.
|
||||
See the file doc/FAQ for frequently asked questions.
|
||||
|
||||
Bison requires GNU m4 1.4.6 or later. See:
|
||||
Bison requires GNU m4 1.4.3 or later. See:
|
||||
|
||||
https://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
|
||||
ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz
|
||||
|
||||
** Relocatability
|
||||
If you pass '--enable-relocatable' to 'configure', Bison is relocatable.
|
||||
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.
|
||||
|
||||
A relocatable program can be moved or copied to a different location on the
|
||||
file system. It can also be used through mount points for network sharing.
|
||||
It is possible to make symlinks to the installed and moved programs, and
|
||||
invoke them through the symlink.
|
||||
Please send bug reports to <[email protected]>. Please include the
|
||||
version number from `bison --version', and a complete, self-contained
|
||||
test case in each bug report.
|
||||
|
||||
See "Enabling Relocatability" in the documentation.
|
||||
|
||||
** Internationalization
|
||||
Bison supports two catalogs: 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.
|
||||
|
||||
* Questions
|
||||
See the section FAQ in the documentation (doc/bison.info) for frequently
|
||||
asked questions. The documentation is also available in PDF and HTML,
|
||||
provided you have a recent version of Texinfo installed: run "make pdf" or
|
||||
"make html".
|
||||
|
||||
If you have questions about using Bison and the documentation does not
|
||||
answer them, please send mail to <[email protected]>.

* Bug reports
|

|
||||
case in each bug report.

This file attempts to describe the rules to use when hacking Bison.
|
||||
Don't put this file into the distribution.
|
||||
|
||||
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 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.
|
||||
|
||||
|
||||
* 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.
|
||||
|
||||
** Horizontal tabs
|
||||
Do not add horizontal tab characters to any file in Bison's repository
|
||||
except where required. For example, do not use tabs to format C code.
|
||||
However, make files, ChangeLog, and some regular expressions require tabs.
|
||||
Also, test cases might need to contain tabs to check that Bison properly
|
||||
processes tabs in its input.

||||

We've opted to keep only the highest-level sources in the repository.
|

This eases our maintenance burden, (fewer merges etc.), but imposes more
|

For example, you have to use the latest stable versions of the maintainer
|

tools we depend upon, including:

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.
|
||||
|
||||

|
||||

|

might be needed.

|

http://savannah.gnu.org/git/?group=bison
|
||||
$ ./bootstrap
|
||||
|
||||
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
|
||||
And there you are! Just
|
||||
|
||||
$ git submodule update --init
|
||||
$ ./configure
|
||||
$ make
|
||||
$ make check
|
||||
|
||||
The next step is to get other files needed to build, which are extracted
|
||||
from other source packages:
|
||||
At this point, there should be no difference between your local copy,
|
||||
and the master copy:
|
||||
|
||||
$ ./bootstrap
|
||||
|
||||
Bootstrapping updates the submodules to the versions registered in the
|
||||
top-level directory. To change gnulib, first check out the version you want
|
||||
in `gnulib`, then commit this change in Bison's repository, and finally run
|
||||
bootstrap.
|
||||
|
||||
If it fails with missing symbols (e.g., "error: possibly undefined macro:
|
||||
AC_PROG_GNU_M4"), you are likely to have forgotten the submodule
|
||||
initialization part. To recover from it, run `git reset --hard HEAD`, and
|
||||
restart with the submodule initialization. Otherwise, there you are! Just
|
||||
|
||||
$ ./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.
|
||||
|
||||
** TESTSUITEFLAGS
|
||||
|
||||
To run just the testsuite (not the tests related to the examples), run `make
|
||||
check-local`.
|
||||
|
||||
The default is for make check-local to run all tests sequentially. This can
|
||||
be very time consuming when checking repeatedly or on slower setups. This
|
||||
can be sped up in two ways:
|
||||
|
||||
Using -j, in a make-like fashion, for example:
|
||||
$ make check-local TESTSUITEFLAGS='-j8'
|
||||
|
||||
Running only the tests of a certain category, as specified in the AT files
|
||||
with AT_KEYWORDS([[category]]). Categories include:
|
||||
- c++, for c++ parsers
|
||||
- deprec, for tests concerning deprecated constructs.
|
||||
- glr, for glr parsers
|
||||
- java, for java parsers
|
||||
- report, for automaton dumps
|
||||
|
||||
To run a specific set of tests, use -k (for "keyword"). For example:
|
||||
$ make check-local TESTSUITEFLAGS='-k c++'
|
||||
|
||||
Both can be combined.
|
||||
|
||||
** 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-check-push", 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-check-xml", 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-check-release" takes care of running
|
||||
maintainer-check, maintainer-check-push and maintainer-check-xml.
|
||||
|
||||
- Change tests/atlocal/CFLAGS to add your preferred options.
|
||||
|
||||
- Test with a very recent version of GCC for both C and C++. Testing with
|
||||
older versions that are still in use is nice too.
|
||||
|
||||
|
||||
* 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.
|
||||
|
||||
The instructions below are obsolete, and left in case one would like to run
|
||||
the commands by hand. Today, one just needs to run
|
||||
|
||||
$ make web-manual-update
|
||||
|
||||
See README-release.
|
||||
|
||||
*** 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.
|
||||
|
||||
** Announce
|
||||
The "make release" 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.

From Franc,ois: should we keep the directory part in the CPP guard?
|
||||
|
||||
|
||||
While at it, we should stop using "$end" by default, in favor of "end of
|
||||
file", or "end of input", whatever.

* Yacc.c: CPP Macros
|
||||
|
||||
** use gettext-h in gnulib instead of gettext
|
||||
** use gnulib-po
|
||||
For some reason, according to syntax-check, we have to keep getopt.c in
|
||||
POTIFILES.in, but not bitset/stats.c, although both come from gnulib. But
|
||||
bitset/stats.c is a symlink, not getopt.c. This is fishy and should be
|
||||
fixed.
|
||||
|
||||
Meanwhile, bitset/stats.c is removed from the set of translations, which is
|
||||
not too much of a problem as users are not expected to see this.
|
||||
Do some people use YYPURE, YYLSP_NEEDED like we do in the test suite?
|
||||
They should not: it is not documented. But if they need to, let's
|
||||
find something clean (not like YYLSP_NEEDED...).
|
||||
|
||||
|
||||
* Completion
|
||||
Several features are not available in all the backends.
|
||||
* Installation

||||
|
||||
- push parsers: glr.cc, lalr1.cc
|
||||
- ielr: C++ and Java
|
||||
- glr: Java
|
||||
- token constructors: Java and C
|
||||
* Documentation
|
||||
Before releasing, make sure the documentation ("Understanding your
|
||||
parser") refers to the current `output' format.
|
||||
|
||||
* Bugs
|
||||
** Autotest has quotation issues
|
||||
tests/input.at:1730:AT_SETUP([%define errors])
|
||||
|
||||
->
|
||||
|
||||
$ ./tests/testsuite -l | grep errors | sed q
|
||||
38: input.at:1730 errors
|
||||
|
||||
* Short term
|
||||
** consistency
|
||||
token vs terminal
|
||||
|
||||
** yacc.c
|
||||
Now that ylwrap is fixed, we should include foo.tab.h from foo.tab.c rather
|
||||
than duplicating it.
|
||||
|
||||
** C++
|
||||
Move to int everywhere instead of unsigned? stack_size, etc. The parser
|
||||
itself uses int (for yylen for instance), yet stack is based on size_t.
|
||||
|
||||
Maybe locations should also move to ints.
|
||||
|
||||
** C
|
||||
Introduce state_type rather than spreading yytype_int16 everywhere?
|
||||
|
||||
** glr.c
|
||||
yyspaceLeft should probably be a pointer diff.
|
||||
|
||||
** Graphviz display code thoughts
|
||||
The code for the --graph option is over two files: print_graph, and
|
||||
graphviz. This is because Bison used to also produce VCG graphs, but since
|
||||
this is no longer true, maybe we could consider these files for fusion.
|
||||
|
||||
An other consideration worth noting is that print_graph.c (correct me if I
|
||||
am wrong) should contain generic functions, whereas graphviz.c and other
|
||||
potential files should contain just the specific code for that output
|
||||
format. It will probably prove difficult to tell if the implementation is
|
||||
actually generic whilst only having support for a single format, but it
|
||||
would be nice to keep stuff a bit tidier: right now, the construction of the
|
||||
bitset used to show reductions is in the graphviz-specific code, and on the
|
||||
opposite side we have some use of \l, which is graphviz-specific, in what
|
||||
should be generic code.
|
||||
|
||||
Little effort seems to have been given to factoring these files and their
|
||||
rint{,-xml} counterpart. We would very much like to re-use the pretty format
|
||||
of states from .output for the graphs, etc.
|
||||
|
||||
Also, the underscore in print_graph.[ch] isn't very fitting considering the
|
||||
dashes in the other filenames.
|
||||
|
||||
Since graphviz dies on medium-to-big grammars, maybe consider an other tool?
|
||||
|
||||
** push-parser
|
||||
Check it too when checking the different kinds of parsers. And be
|
||||
sure to check that the initial-action is performed once per parsing.
|
||||
|
||||
** m4 names
|
||||
b4_shared_declarations is no longer what it is. Make it
|
||||
b4_parser_declaration for instance.
|
||||
|
||||
** yychar in lalr1.cc
|
||||
There is a large difference bw maint and master on the handling of
|
||||
yychar (which was removed in lalr1.cc). See what needs to be
|
||||
back-ported.
|
||||
|
||||
|
||||
/* User semantic actions sometimes alter yychar, and that requires
|
||||
that yytoken be updated with the new translation. We take the
|
||||
approach of translating immediately before every use of yytoken.
|
||||
One alternative is translating here after every semantic action,
|
||||
but that translation would be missed if the semantic action
|
||||
invokes YYABORT, YYACCEPT, or YYERROR immediately after altering
|
||||
yychar. In the case of YYABORT or YYACCEPT, an incorrect
|
||||
destructor might then be invoked immediately. In the case of
|
||||
YYERROR, subsequent parser actions might lead to an incorrect
|
||||
destructor call or verbose syntax error message before the
|
||||
lookahead is translated. */
|
||||
|
||||
/* Make sure we have latest lookahead translation. See comments at
|
||||
user semantic actions for why this is necessary. */
|
||||
yytoken = yytranslate_ (yychar);
|
||||
|
||||
|
||||
** Get rid of fake #lines [Bison: ...]
|
||||
Possibly as simple as checking whether the column number is nonnegative.
|
||||
|
||||
I have seen messages like the following from GCC.
|
||||
|
||||
<built-in>:0: fatal error: opening dependency file .deps/libltdl/argz.Tpo: No such file or directory
|
||||
|
||||
|
||||
** 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
|
||||
|
||||
%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).
|
||||
|
||||
** Rename LR0.cc
|
||||
as lr0.cc, why upper case?
|
||||
|
||||
* Various
|
||||
** Rewrite glr.cc in C++
|
||||
As a matter of fact, it would be very interesting to see how much we can
|
||||
share between lalr1.cc and glr.cc. Most of the skeletons should be common.
|
||||
It would be a very nice source of inspiration for the other languages.
|
||||
|
||||
** 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.
|
||||
|
||||
enum yytokentype {
|
||||
error = 256,
|
||||
// ...
|
||||
};
|
||||
|
||||
|
||||
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:
|
||||
|
||||
const unsigned short
|
||||
parser::yytoken_number_[] =
|
||||
{
|
||||
0, 256, 257, 258, 259, 260, 261, 262, 263, 264,
|
||||
|
||||
while here
|
||||
|
||||
enum yytokentype {
|
||||
TOK_EOF = 0,
|
||||
TOK_EQ = 258,
|
||||
|
||||
so both 256 and 257 are "mysterious".
|
||||
|
||||
const char*
|
||||
const parser::yytname_[] =
|
||||
{
|
||||
"\"end of command\"", "error", "$undefined", "\"=\"", "\"break\"",
|
||||
|
||||
|
||||
** 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.
|
||||
|
||||
* 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:

should make this reasonably easy to implement.

|

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:

** Push parsers

There is demand for push parsers in Java and C++. And GLR I guess.

r:exp -> a:exp '+' b:exp { r = a + b; };
|
||||
|
||||
That requires an significant improvement of the grammar parser. Using

GLR would be nice. It also requires that Bison know the type of the

symbols (which will be useful for %include anyway). So we have some

time before...

Paul notes:

Currently Bison assumes 8-bit bytes (i.e. that UCHAR_MAX is
|
||||
255). It also assumes that the 8-bit character encoding is
|
||||
the same for the invocation of 'bison' as it is for the
|
||||
invocation of 'cc', but this is not necessarily true when
|
||||
people run bison on an ASCII host and then use cc on an EBCDIC
|

host. I don't think these topics are worth our time

needed to support some extra BTYacc features. This is less urgent.
|
||||
|

** Keeping the conflicted actions
|

First, analyze the differences between byacc and btyacc (I'm referring

to the executables). Find where the conflicts are preserved.

** Compare with the GLR tables

Bison are compatible. *As much as possible* one should try to use the

very feasible to use the very same conflict tables.

** Correlation b/w precedence and associativity

Also, I fail to understand why we have to assign the same

associativity to operators with the same precedence. For instance,

why can't I decide that the precedence of * and / is the same, but the

latter is nonassoc?

* Default Action
|
||||
From Hans:
|
||||
- For use with my C++ parser, I transported the "switch (yyn)" statement
|
||||
that Bison writes to the bison.simple skeleton file. This way, I can remove
|
||||
the current default rule $$ = $1 implementation, which causes a double
|
||||
assignment to $$ which may not be OK under C++, replacing it with a
|
||||
"default:" part within the switch statement.
|
||||
|
||||
Note that the default rule $$ = $1, when typed, is perfectly OK under C,
|
||||
but in the C++ implementation I made, this rule is different from
|
||||
$<type_name>$ = $<type_name>1. I therefore think that one should implement
|
||||
a Bison option where every typed default rule is explicitly written out
|
||||
(same typed ruled can of course be grouped together).
|
||||
|
||||
Note: Robert Anisko handles this. He knows how to do it.

* Warnings

It would be nice to have warning support. See how Autoconf handles

them, it is fairly well described there. It would be very nice to

implement this in such a way that other programs could use

* Better graphics
|

Equip the parser with a means to create the (visual) parse tree.

||||
* Complaint submessage indentation.
|
||||
We already have an implementation that works fairly well for named
|
||||
reference messages, but it would be nice to use it consistently for all
|
||||
submessages from Bison. For example, the "previous definition"
|
||||
submessage or the list of correct values for a %define variable might
|
||||
look better with indentation.
|
||||
|
||||
However, the current implementation makes the assumption that the
|
||||
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
|
||||
we ever support multiple grammar files.
|
||||
|
||||
Here's a proposal for how a new implementation might look:

This directory contains 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.

# Implementation note about the skeletons
|
||||
|
||||
"Skeleton" in Bison parlance means "backend": a skeleton is fed by the bison
|
||||
executable with LR tables, facts about the symbols, etc. and they generate
|
||||
the output (say parser.cc, parser.hh, location.hh, etc.). They are only in
|
||||
charge of generating the parser and its auxiliary files, they do not
|
||||
generate the XML output, the parser.output reports, nor the graphical
|
||||
rendering.
|
||||
|
||||
The bits of information passing from bison to the backend is named
|
||||
"muscles". Muscles are passed to M4 via its standard input: it's a set of
|
||||
m4 definitions. To see them, use `--trace=muscles`.
|
||||
|
||||
Except for muscles, whose names are generated by bison, the skeletons have
|
||||
no constraint at all on the macro names: there is no technical/theoretical
|
||||
limitation, as long as you generate the output, you can do what you want.
|
||||
However, of course, that would be a bad idea if, say, the C and C++
|
||||
skeletons used different approaches and had completely different
|
||||
implementations. That would be a maintenance nightmare.
|
||||
|
||||
Below, we document some of the macros that we use in several of the
|
||||
skeletons. If you are to write a new skeleton, please, implement them for
|
||||
your language. Overall, be sure to follow the same patterns as the existing
|
||||
skeletons.
|
||||
|
||||
## Symbols
|
||||
|
||||
### `b4_symbol(NUM, FIELD)`
|
||||
In order to unify the handling of the various aspects of symbols (tag, type
|
||||
name, whether terminal, etc.), bison.exe defines one macro per (token,
|
||||
field), where field can `has_id`, `id`, etc.: see
|
||||
`prepare_symbols_definitions()` in `src/output.c`.
|
||||
|
||||
The macro `b4_symbol(NUM, FIELD)` gives access to the following FIELDS:
|
||||
|
||||
- `has_id`: 0 or 1.
|
||||
|
||||
Whether the symbol has an id.
|
||||
|
||||
- `id`: string
|
||||
If has_id, the id (prefixed by api.token.prefix if defined), otherwise
|
||||
defined as empty. Guaranteed to be usable as a C identifier.
|
||||
|
||||
- `tag`: string.
|
||||
A representation of the symbol. Can be 'foo', 'foo.id', '"foo"' etc.
|
||||
|
||||
- `user_number`: integer
|
||||
The external number as used by yylex. Can be ASCII code when a character,
|
||||
some number chosen by bison, or some user number in the case of
|
||||
%token FOO <NUM>. Corresponds to yychar in yacc.c.
|
||||
|
||||
- `is_token`: 0 or 1
|
||||
Whether this is a terminal symbol.
|
||||
|
||||
- `number`: integer
|
||||
The internal number (computed from the external number by yytranslate).
|
||||
Corresponds to yytoken in yacc.c. This is the same number that serves as
|
||||
key in b4_symbol(NUM, FIELD).
|
||||
|
||||
In bison, symbols are first assigned increasing numbers in order of
|
||||
appearance (but tokens first, then nterms). After grammar reduction,
|
||||
unused nterms are then renumbered to appear last (i.e., first tokens, then
|
||||
used nterms and finally unused nterms). This final number NUM is the one
|
||||
contained in this field, and it is the one used as key in `b4_symbol(NUM,
|
||||
FIELD)`.
|
||||
|
||||
The code of the rule actions, however, is emitted before we know what
|
||||
symbols are unused, so they use the original numbers. To avoid confusion,
|
||||
they actually use "orig NUM" instead of just "NUM". bison also emits
|
||||
definitions for `b4_symbol(orig NUM, number)` that map from original
|
||||
numbers to the new ones. `b4_symbol` actually resolves `orig NUM` in the
|
||||
other case, i.e., `b4_symbol(orig 42, tag)` would return the tag of the
|
||||
symbols whose original number was 42.
|
||||
|
||||
- `has_type`: 0, 1
|
||||
Whether has a semantic value.
|
||||
|
||||
- `type_tag`: string
|
||||
When api.value.type=union, the generated name for the union member.
|
||||
yytype_INT etc. for symbols that has_id, otherwise yytype_1 etc.
|
||||
|
||||
- `type`
|
||||
If it has a semantic value, its type tag, or, if variant are used,
|
||||
its type.
|
||||
In the case of api.value.type=union, type is the real type (e.g. int).
|
||||
|
||||
- `has_printer`: 0, 1
|
||||
- `printer`: string
|
||||
- `printer_file`: string
|
||||
- `printer_line`: integer
|
||||
If the symbol has a printer, everything about it.
|
||||
|
||||
- `has_destructor`, `destructor`, `destructor_file`, `destructor_line`
|
||||
Likewise.
|
||||
|
||||
### `b4_symbol_value(VAL, [SYMBOL-NUM], [TYPE-TAG])`
|
||||
Expansion of $$, $1, $<TYPE-TAG>3, etc.
|
||||
|
||||
The semantic value from a given VAL.
|
||||
- `VAL`: some semantic value storage (typically a union). e.g., `yylval`
|
||||
- `SYMBOL-NUM`: the symbol number from which we extract the type tag.
|
||||
- `TYPE-TAG`, the user forced the `<TYPE-TAG>`.
|
||||
|
||||
The result can be used safely, it is put in parens to avoid nasty precedence
|
||||
issues.
|
||||
|
||||
### `b4_lhs_value(SYMBOL-NUM, [TYPE])`
|
||||
Expansion of `$$` or `$<TYPE>$`, for symbol `SYMBOL-NUM`.
|
||||
|
||||
### `b4_rhs_data(RULE-LENGTH, POS)`
|
||||
The data corresponding to the symbol `#POS`, where the current rule has
|
||||
`RULE-LENGTH` symbols on RHS.
|
||||
|
||||
### `b4_rhs_value(RULE-LENGTH, POS, SYMBOL-NUM, [TYPE])`
|
||||
Expansion of `$<TYPE>POS`, where the current rule has `RULE-LENGTH` symbols
|
||||
on RHS.
|
||||
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.

# This skeleton produces a C++ class that encapsulates a C glr parser.
|
||||
# This is in order to reduce the maintenance burden. The glr.c
|
||||
# skeleton is clean and pure enough so that there are no real
|
||||
# problems. The C++ interface is the same as that of lalr1.cc. In
|
||||
# fact, glr.c can replace yacc.c without the user noticing any
|

# difference, and similarly for glr.cc replacing lalr1.cc.

#
|
||||
# The passing of parse-params
|
||||
#
|
||||
# The additional arguments are stored as members of the parser
|
||||
# object, yyparser. The C routines need to carry yyparser
|
||||
# throughout the C parser; that easy: just let yyparser become an
|
||||
# additional parse-param. But because the C++ skeleton needs to
|
||||
# know the "real" original parse-param, we save them
|
||||
# (b4_parse_param_orig). Note that b4_parse_param is overquoted
|
||||
# (and c.m4 strips one level of quotes). This is a PITA, and
|
||||
# explains why there are so many levels of quotes.
|
||||
#
|
||||
# The locations
|
||||
#
|
||||
# We use location.cc just like lalr1.cc, but because glr.c stores
|
||||
# the locations in a (C++) union, the position and location classes
|
||||
# must not have a constructor. Therefore, contrary to lalr1.cc, we
|
||||
# must not define "b4_location_constructors". As a consequence the
|
||||
# user must initialize the first positions (in particular the

Some usage notes for the D Parser:
|
||||
|
||||
- it is a port of the Java parser, so interface is very similar.
|
||||
|
||||
- the lexer class needs to implement the interface 'Lexer' (similar to
|
||||
java). It typically (depending on options) looks like this:
|
||||
|
||||
public interface Lexer
|
||||
{
|
||||
/**
|
||||
* Method to retrieve the beginning position of the last scanned token.
|
||||
* @return the position at which the last scanned token starts. */
|
||||
@property YYPosition startPos ();
|
||||
|
||||
/**
|
||||
* Method to retrieve the ending position of the last scanned token.
|
||||
* @return the first position beyond the last scanned token. */
|
||||
@property YYPosition endPos ();
|
||||
|
||||
/**
|
||||
* Method to retrieve the semantic value of the last scanned token.
|
||||
* @return the semantic value of the last scanned token. */
|
||||
@property YYSemanticType semanticVal ();
|
||||
|
||||
/**
|
||||
* Entry point for the scanner. Returns the token identifier corresponding
|
||||
* to the next token and prepares to return the semantic value
|
||||
* and beginning/ending positions of the token.
|
||||
* @return the token identifier corresponding to the next token. */
|
||||
YYTokenType yylex ();
|
||||
|
||||
/**
|
||||
* Entry point for error reporting. Emits an error
|
||||
* referring to the given location in a user-defined way.
|
||||
*
|
||||
* @param loc The location of the element to which the
|
||||
* error message is related
|
||||
* @param s The string for the error message. */
|
||||
void yyerror (YYLocation loc, string s);
|
||||
}
|
||||
|
||||
- semantic types are handled by D usions (same as for C/C++ parsers)
|
||||
|
||||
- the following (non-standard) %defines are supported:
|
||||
|
||||
%define package "<package_name>"
|
||||
%define api.parser.class "my_class_name>"
|
||||
%define position_type "my_position_type"
|
||||
%define location_type "my_location_type"
|
||||
|
||||
- the following declarations basically work like in C/C++:
|
||||
|
||||
%locations
|
||||
%error-verbose
|
||||
%parse-param
|
||||
%initial-action
|
||||
%code
|
||||
%union
|
||||
|
||||
- %destructor is not yet supported

# This skeleton produces a C++ class that encapsulates a C glr parser.
|
||||
# This is in order to reduce the maintenance burden. The glr.c
|
||||
# skeleton is clean and pure enough so that there are no real
|
||||
# problems. The C++ interface is the same as that of lalr1.cc. In
|
||||
# fact, glr.c can replace yacc.c without the user noticing any
|
||||
# difference, and similarly for glr.cc replacing lalr1.cc.
|
||||
#
|
||||
# The passing of parse-params
|
||||
#
|
||||
# The additional arguments are stored as members of the parser
|
||||
# object, yyparser. The C routines need to carry yyparser
|
||||
# throughout the C parser; that's easy: make yyparser an
|
||||
# additional parse-param. But because the C++ skeleton needs to
|
||||
# know the "real" original parse-param, we save them
|
||||
# (b4_parse_param_orig). Note that b4_parse_param is overquoted
|
||||
# (and c.m4 strips one level of quotes). This is a PITA, and
|
||||
# explains why there are so many levels of quotes.
|
||||
#
|
||||
# The locations
|
||||
#
|
||||
# We use location.cc just like lalr1.cc, but because glr.c stores
|
||||
# the locations in a union, the position and location classes
|
||||
# must not have a constructor. Therefore, contrary to lalr1.cc, we
|
||||
# must not define "b4_location_constructors". As a consequence the
|
||||
# user must initialize the first positions (in particular the
|
||||
# filename member).

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.

|
||||
|
||||
|
||||
1.: DJGPP specific changes.
|
||||
=======================
|
||||
|
||||
The DJGPP port of Bison offers LFN and SFN support depending on which
|
||||
OS it is running. If LFN support is available or not is determinated at
|
||||
run time. If LFN support is available (DOS session under Win9X, Win2K,
|
||||
WinXP, etc.) the standard posix file name extensions will be used.
|
||||
These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc. If only SFN
|
||||
support is available (plain DOS), then the standard MSDOS short file
|
||||
names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
|
||||
It should be noticed that this bison version needs the m4 program as
|
||||
back end to generate the parser file (y.tab.c etc.) from the skeleton
|
||||
files. This implies that m4 must always be installed to get bison
|
||||
working. m4 will use a couple of m4 scripts that will be installed in
|
||||
/dev/env/DJDIR/share/bison and shall not be removed.
|
||||
It should also be noticed that the skeleton files bison.simple and
|
||||
bison.hairy are no longer supported. This applies also to the environ-
|
||||
ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
|
||||
longer honored at all.
|
||||
The kind of skeleton file bison.hairy is no longer supported at all.
|
||||
The skeleton file bison.simple is now called yacc.c and is an m4 script.
|
||||
The other two skeleton files supported by this bison version are glr.c
|
||||
and lalr1.cc. The first one is a generalized LR C parser based on
|
||||
Bison's LALR(1) tables and the second one is a experimental C++ parser
|
||||
class.
|
||||
As has been told before, bison uses m4 to generate the parser file.
|
||||
This is done by forking and using pipes for the IPC. MSDOS does not
|
||||
support this functionality so this has been reproduced in the usual
|
||||
way by redirecting stdin and stdout of bison and m4 to temporary files
|
||||
and processing these files in sequence.
|
||||
It should be noticed that due to the great amount of file names that do
|
||||
not cleanly map to 8.3 file names, you will need an OS with LFN support
|
||||
to configure and compile the sources. On Win98 this implies that the
|
||||
generation of numeric tails for 8.3 file name aliases must be enabled
|
||||
or the compilation will fail.
|
||||
|
||||
|
||||
Please **read** the docs.
|
||||
|
||||
|
||||
2.: Installing the binary package.
|
||||
==============================
|
||||
|
||||
2.1.: Copy the binary distribution into the top DJGPP installation directory,
|
||||
just unzip it preserving the directory structure running *ONE* of the
|
||||
following commands:
|
||||
unzip32 bsn@[email protected] or
|
||||
djtarx bsn@[email protected] or
|
||||
pkunzip -d bsn@[email protected]
|
||||
|
||||
|
||||
|
||||
3.: Building the binaries from sources.
|
||||
===================================
|
||||
|
||||
3.1.: Create a temporary directory and copy the source package into the
|
||||
directory. If you download the source distribution from one of the
|
||||
DJGPP sites, just unzip it preserving the directory structure
|
||||
running *ONE* of the following commands:
|
||||
unzip32 bsn@[email protected] or
|
||||
djtarx bsn@[email protected] or
|
||||
pkunzip -d bsn@[email protected]
|
||||
and proceed to the paragraph 3.3, below.
|
||||
|
||||
3.2.: Source distributions downloaded from one of the GNU FTP sites need
|
||||
some more work to unpack, if LFN support is not available. If LFN is
|
||||
available then you can extract the source files from the archive with
|
||||
any unzip program and proceed to the paragraph 3.3, below. Any file
|
||||
name issue will be handled by the the DJGPP configuration files.
|
||||
To unpack the source distribution on SFN systems, first, you MUST use
|
||||
the `djunpack' batch file to unzip the package. That is because some
|
||||
file names in the official distributions need to be changed to avoid
|
||||
problems on the various platforms supported by DJGPP.
|
||||
`djunpack' invokes the `djtar' program (that is part of the basic DJGPP
|
||||
development kit) to rename these files on the fly given a file with
|
||||
name mappings; the distribution includes a file `djgpp/fnchange.lst'
|
||||
with the necessary mappings. So you need first to retrieve that batch
|
||||
file, and then invoke it to unpack the distribution. Here's how:
|
||||
|
||||
djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
|
||||
djunpack bison-@[email protected]
|
||||
|
||||
(The name of the distribution archive and the leading directory of the
|
||||
path to `djunpack.bat' in the distribution will be different for
|
||||
versions of Bison other than @VERSION@.)
|
||||
|
||||
If the argument to `djunpack.bat' include leading directories, it MUST
|
||||
be given with the DOS-style backslashes; Unix-style forward slashes
|
||||
will NOT work.
|
||||
|
||||
If the distribution comes as a .tar.bz2 archive, and your version of
|
||||
`djtar' doesn't support bzip2 decompression, you need to unpack it as
|
||||
follows:
|
||||
|
||||
bnzip2 bison-@[email protected]
|
||||
djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@[email protected] > djunpack.bat
|
||||
djunpack bison-@[email protected]
|
||||
|
||||
3.3.: To build the binaries you will need the following binary packages:
|
||||
djdev203.zip (or a later but NOT a prior version)
|
||||
bsh204b.zip (or a later but NOT a prior version)
|
||||
gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
|
||||
perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip,
|
||||
sedNNNb.zip and m4NNN.zip
|
||||
|
||||
If you want to run the check you will need also:
|
||||
difNNNb.zip
|
||||
|
||||
NNN represents the latest version number of the binary packages. All
|
||||
this packages can be found in the /v2gnu directory of any
|
||||
ftp.delorie.com mirror.
|
||||
You will need bsh204b.zip or later and *NOT* a prior version or
|
||||
the build will fail. The same applies to djdev203.zip. Please note
|
||||
that Bison requires m4-144b.zip or later to work properly.
|
||||
|
||||
3.4.: If for some reason you want to reconfigure the package cd into the top
|
||||
srcdir (bison-@TREE_VERSION@) and run the following commands:
|
||||
del djgpp\config.cache
|
||||
make clean
|
||||
djgpp\config
|
||||
|
||||
Please note that you *MUST* delete the config.cache file in the djgpp
|
||||
subdir or you will not really reconfigure the sources because the
|
||||
configuration informations will be read from the cache file instead
|
||||
of being newly computed.
|
||||
To build the programs in a directory other than where the sources are,
|
||||
you must add the parameter that specifies the source directory,
|
||||
e.g:
|
||||
x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
|
||||
|
||||
Lets assume you want to build the binaries in a directory placed on a
|
||||
different drive (z:\build in this case) from where the sources are,
|
||||
then you will run the following commands:
|
||||
z:
|
||||
md \build
|
||||
cd \build
|
||||
x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
|
||||
|
||||
The order of the options and the srcdir option does not matter. You
|
||||
*MUST* use forward slashes to specify the source directory.
|
||||
|
||||
The batch file will set same environment variables, make MSDOS specific
|
||||
modifications to the Makefile.in's and supply all other needed options
|
||||
to the configure script.
|
||||
|
||||
3.5.: To compile the package run from the top srcdir the command:
|
||||
make
|
||||
|
||||
3.6.: Now you can run the tests if you like. From the top srcdir run the
|
||||
command:
|
||||
make check
|
||||
|
||||
No test should fail but the tests #131 (Doxygen Public Documentation)
|
||||
and #132 (Doxygen Private Documentation) will be skipped. Please note
|
||||
that the testsuite only works with LFN available. On plain DOS, most
|
||||
of the tests will fail due to invalid DOS names.
|
||||
|
||||
3.7.: To install the binaries, header, library, catalogs, and info docs
|
||||
run the following command from the top srcdir:
|
||||
make install
|
||||
|
||||
This will install the products into your DJGPP installation tree given
|
||||
by the default prefix "/dev/env/DJDIR". If you prefer to install them
|
||||
into some other directory you will have to set prefix to the appropiate
|
||||
value:
|
||||
make install prefix=z:/some/other/place

|
||||
.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.
