|

GNU Bison is a general-purpose parser generator that converts an annotated
|
||||
context-free grammar into a deterministic LR or generalized LR (GLR) parser
|
||||
employing LALR(1) parser tables. Bison can also generate IELR(1) or
|
||||
canonical LR(1) parser tables. Once you are proficient with Bison, you can
|
||||
use it to develop a wide range of language parsers, from those used in
|
||||
simple desk calculators to complex programming languages.
|
||||
This package contains the GNU Bison parser generator.
|
||||
|
||||
Bison is upward compatible with Yacc: all properly-written Yacc grammars
|
||||
work with Bison with no change. Anyone familiar with Yacc should be able to
|
||||
use Bison with little trouble. You need to be fluent in C, C++ or Java
|
||||
programming in order to use Bison.
|
||||
* Installation
|
||||
** Build
|
||||
See the file INSTALL for generic compilation and installation
|
||||
instructions.
|
||||
|
||||
Bison and the parsers it generates are portable, they do not require any
|
||||
specific compilers.
|
||||
Bison requires GNU m4 1.4.6 or later. See:
|
||||
|
||||
GNU Bison's home page is https://gnu.org/software/bison/.
|
||||
ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
|
||||
|
||||
# Installation
|
||||
## Build from git
|
||||
Here are basic installation instructions for a repository checkout:
|
||||
** 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.
|
||||
|
||||
$ git submodule update --init
|
||||
$ ./bootstrap
|
||||
* 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".
|
||||
|
||||
then proceed with the usual `configure && make` steps.
|
||||
If you have questions about using Bison and the documentation does
|
||||
not answer them, please send mail to <[email protected]>.
|
||||
|
||||
The file README-hacking.md is about building, modifying and checking Bison.
|
||||
* Bug reports
|
||||
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.
|
||||
|
||||
## Build from tarball
|
||||
See the file INSTALL for generic compilation and installation instructions.
|
||||
* Copyright statements
|
||||
For any copyright year range specified as YYYY-ZZZZ in this package,
|
||||
note that the range specifies every single year in that closed interval.
|
||||
|
||||
Bison requires GNU m4 1.4.6 or later. See
|
||||
https://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz.
|
||||
|
||||
## Running a non installed bison
|
||||
Once you ran `make`, you might want to toy with this fresh bison before
|
||||
installing it. In that case, do not use `src/bison`: it would use the
|
||||
*installed* files (skeletons, etc.), not the local ones. Use `tests/bison`.
|
||||
|
||||
## Colored diagnostics
|
||||
As an experimental feature, diagnostics are now colored, controlled by the
|
||||
`--color` and `--style` options.
|
||||
|
||||
To use them, install the libtextstyle library before configuring Bison. It
|
||||
is available from https://alpha.gnu.org/gnu/gettext/, for instance
|
||||
https://alpha.gnu.org/pub/gnu/gettext/libtextstyle-0.20.5.tar.gz.
|
||||
|
||||
The option --color supports the following arguments:
|
||||
- always, yes: Enable colors.
|
||||
- never, no: Disable colors.
|
||||
- auto, tty (default): Enable colors if the output device is a tty.
|
||||
|
||||
To customize the styles, create a CSS file, say `bison-bw.css`, similar to
|
||||
|
||||
/* bison-bw.css */
|
||||
.warning { }
|
||||
.error { font-weight: 800; text-decoration: underline; }
|
||||
.note { }
|
||||
|
||||
then invoke bison with `--style=bison-bw.css`, or set the `BISON_STYLE`
|
||||
environment variable to `bison-bw.css`.
|
||||
|
||||
## Relocatability
|
||||
If you pass `--enable-relocatable` to `configure`, Bison is relocatable.
|
||||
|
||||
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.
|
||||
|
||||
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.

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.
|
||||
|
||||
|
||||
* Working from the repository
|
||||
|
||||
These notes intend to help people working on the checked-out sources.
|
||||
These requirements do not apply when building from a distribution tarball.
|
||||
|
||||
** Requirements
|
||||
|
||||
We've opted to keep only the highest-level sources in the repository. This
|
||||
eases our maintenance burden, (fewer merges etc.), but imposes more
|
||||
requirements on anyone wishing to build from the just-checked-out sources.
|
||||
For example, you have to use the latest stable versions of the maintainer
|
||||
tools we depend upon, including:
|
||||
|
||||
- Autoconf <http://www.gnu.org/software/autoconf/>
|
||||
- Automake <http://www.gnu.org/software/automake/>
|
||||
- Flex <http://www.gnu.org/software/flex/>
|
||||
- Gettext <http://www.gnu.org/software/gettext/>
|
||||
- Graphviz <http://www.graphviz.org>
|
||||
- Gzip <http://www.gnu.org/software/gzip/>
|
||||
- Help2man <http://www.gnu.org/software/help2man/>
|
||||
- Perl <http://www.cpan.org/>
|
||||
- Rsync <http://samba.anu.edu.au/rsync/>
|
||||
- Tar <http://www.gnu.org/software/tar/>
|
||||
- Texinfo <http://www.gnu.org/software/texinfo/>
|
||||
|
||||
Valgrind <http://valgrind.org/> is also highly recommended, if it supports
|
||||
your architecture.
|
||||
|
||||
If you're using a GNU/Linux distribution, the easiest way to install the
|
||||
above packages depends on your system. The following shell command should
|
||||
work for Debian-based systems such as Ubuntu:
|
||||
|
||||
sudo apt-get install \
|
||||
autoconf automake autopoint flex graphviz help2man texinfo valgrind
|
||||
|
||||
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
|
||||
|
||||
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, upgrade Git if
|
||||
your version is older.
|
||||
|
||||
The next step is to get other files needed to build, which are
|
||||
extracted from other source packages:
|
||||
|
||||
$ ./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. 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
|
||||
|
||||
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
|
||||
|
||||
The default is for make check to run all tests sequentially. This can be
|
||||
very time consumming 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 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 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-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.
|
||||
|
||||
- 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.
|
||||
|
||||
*** 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.

=============
|
||||
|
||||
## 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.
|
||||
|
||||
## Syntax highlighting
|
||||
It's quite nice to be in C++ mode when editing lalr1.cc for instance.
|
||||
However tools such as Emacs will be fooled by the fact that braces and
|
||||
parens do not nest, as in `[[}]]`. As a consequence you might be misguided
|
||||
by its visual pairing to parens. The m4-mode is safer. Unfortunately the
|
||||
m4-mode is also fooled by `#` which is sees as a comment, stops pairing with
|
||||
parens/brackets that are inside...
|
||||
|
||||
## Coding Style
|
||||
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.
|
||||
|
||||
Prefer "res" as the name of the local variable that will be "return"ed by
|
||||
the function.
|
||||
|
||||
### Bison
|
||||
Follow the GNU Coding Standards.
|
||||
|
||||
Don't reinvent the wheel: we use gnulib, which features many components.
|
||||
Actually, Bison has legacy code that we should replace with gnulib modules
|
||||
(e.g., many ad hoc implementations of lists).
|
||||
|
||||
### Skeletons
|
||||
We try to use the "typical" coding style for each language.
|
||||
|
||||
#### CPP
|
||||
We indent the CPP directives this way:
|
||||
|
||||
```
|
||||
#if FOO
|
||||
# if BAR
|
||||
# define BAZ
|
||||
# endif
|
||||
#endif
|
||||
```
|
||||
|
||||
Don't indent with leading spaces in the skeletons (it's ok in the grammar
|
||||
files though, e.g., in `%code {...}` blocks).
|
||||
|
||||
On occasions, use `cppi -c` to see where we stand. We don't aim at full
|
||||
correctness: depending `-d`, some bits can be in the *.c file, or the *.h
|
||||
file within the double-inclusion cpp-guards. In that case, favor the case
|
||||
of the *.h file, but don't waste time on this.
|
||||
|
||||
Don't hesitate to leave a comment on the `#endif` (e.g., `#endif /* FOO
|
||||
*/`), especially for long blocks.
|
||||
|
||||
There is no conistency on `! defined` vs. `!defined`. The day gnulib
|
||||
decides, we'll follow them.
|
||||
|
||||
#### C/C++
|
||||
Follow the GNU Coding Standards.
|
||||
|
||||
The `glr.c` skeleton was implemented with `camlCase`. We are migrating it
|
||||
to `snake_case`. Because we are standardizing the code, it is currently
|
||||
inconsistent.
|
||||
|
||||
Use `YYFOO` and `yyfoo` for entities that are exposed to the user. They are
|
||||
part of our contract with the users wrt backward compatibility.
|
||||
|
||||
Use `YY_FOO` and `yy_foo` for private matters. Users should not use them,
|
||||
we are free to change them without fear of backward compatibility issues.
|
||||
|
||||
Use `*_t` for types, especially for `yy*_t` in which case we shouldn't worry
|
||||
about the C standard introducing such a name.
|
||||
|
||||
#### C++
|
||||
Follow the C++ Core Guidelines
|
||||
(http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines). The Google
|
||||
ones may be interesting too
|
||||
(https://google.github.io/styleguide/cppguide.html).
|
||||
|
||||
Our enumerators, such as the kinds (symbol and token kinds), should be lower
|
||||
case, but it was too late to follow that track for token kinds, and symbol
|
||||
kind enumerators are made to be consistent with them.
|
||||
|
||||
Use `*_type` for type aliases. Use `foo_get()` and `foo_set(v)` for
|
||||
accessors, or simply `foo()` and `foo(v)`.
|
||||
|
||||
Use the `yy` prefix for private stuff, but there's no need for it in the
|
||||
public API. The `yy` prefix is already taken care of via the namespace.
|
||||
|
||||
#### Java
|
||||
We follow https://www.oracle.com/technetwork/java/codeconventions-150003.pdf
|
||||
and https://google.github.io/styleguide/javaguide.html. Unfortunately at
|
||||
some point some GNU Coding Style was installed in Java, but it's an error.
|
||||
So we should for instance stop putting spaces in function calls. Because we
|
||||
are standardizing the code, it is currently inconsistent.
|
||||
|
||||
Use a 2-space indentation (Google) rather than 4 (Oracle).
|
||||
|
||||
Don't use the "yy" prefix for public members: "getExpectedTokens", not
|
||||
"yyexpectedTokens" or "yygetExpectedTokens".
|
||||
|
||||
## Commit Messages
|
||||
Imitate the style we use. Use `git log` to get sources of inspiration.
|
||||
|
||||
If the changes have a small impact on Bison's generated parser, embed these
|
||||
changes in the commit itself. If the impact is large, first push all the
|
||||
changes except those about src/parse-gram.[ch], and then another commit
|
||||
named "regen" which is only about them.
|
||||
|
||||
## Debugging

Bison supports tracing of its various steps, via the `--trace` option.
|
||||
Since it is not meant for the end user, it is not displayed by `bison
|
||||
--help`, nor is it documented in the manual. Instead, run `bison
|
||||
--trace=help`.

Working from the Repository
|
||||
===========================
|
||||
|
||||
These notes intend to help people working on the checked-out sources. These
|
||||
requirements do not apply when building from a distribution tarball.
|
||||
|
||||
## Requirements
|
||||
|
||||
We've opted to keep only the highest-level sources in the repository. This
|
||||
eases our maintenance burden, (fewer merges etc.), but imposes more
|
||||
requirements on anyone wishing to build from the just-checked-out sources.
|
||||
For example, you have to use the latest stable versions of the maintainer
|
||||
tools we depend upon, including:
|
||||
|
||||
- Autoconf <http://www.gnu.org/software/autoconf/>
|
||||
- Automake <http://www.gnu.org/software/automake/>
|
||||
- Flex <http://www.gnu.org/software/flex/>
|
||||
- Gettext <http://www.gnu.org/software/gettext/>
|
||||
- Graphviz <http://www.graphviz.org>
|
||||
- Gzip <http://www.gnu.org/software/gzip/>
|
||||
- Help2man <http://www.gnu.org/software/help2man/>
|
||||
- Perl <http://www.cpan.org/>
|
||||
- Rsync <http://samba.anu.edu.au/rsync/>
|
||||
- Tar <http://www.gnu.org/software/tar/>
|
||||
- Texinfo <http://www.gnu.org/software/texinfo/>
|
||||
|
||||
Valgrind <http://valgrind.org/> is also highly recommended, if it supports
|
||||
your architecture.
|
||||
|
||||
If you're using a GNU/Linux distribution, the easiest way to install the
|
||||
above packages depends on your system. The following shell command should
|
||||
work for Debian-based systems such as Ubuntu:
|
||||
|
||||
sudo apt-get install \
|
||||
autoconf automake autopoint flex graphviz help2man texinfo valgrind
|
||||
|
||||
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
|
||||
|
||||
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
|
||||
|
||||
The next step is to get other files needed to build, which are extracted
|
||||
from other source packages:
|
||||
|
||||
$ ./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
|
||||
|
||||
should output no difference.
|
||||
|
||||
Enjoy!
|
||||
|
||||
## Updating
|
||||
|
||||
If you have git at version 1.8.2 or later, the command
|
||||
|
||||
$ git submodule update --recursive --remote
|
||||
|
||||
will be useful for updating to the latest version of all submodules.
|
||||
|
||||
Under earlier versions, use of submodules make things somewhat different
|
||||
because git does not yet support recursive operations: submodules must be
|
||||
taken care of explicitly.
|
||||
|
||||
### 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 commit ...
|
||||
|
||||
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.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
Bison is self-hosted: its parser is generated by Bison. We don't force
|
||||
ourselves to use the previous release of Bison, we use the current git
|
||||
master for several reasons:
|
||||
- dogfooding: let Bison be its first user
|
||||
- monitoring: seeing the diff on the generated parsers with git is very
|
||||
helpful, as it allows to see easily the impact of the changes on a real
|
||||
case parser.
|
||||
|
||||
If you are unlucky the generated files, src/parse-gram.[ch], may be older
|
||||
than their source, src/parse-gram.y. And your current version of Bison
|
||||
might not be able to grok it. In that case, first refresh the generated
|
||||
files:
|
||||
|
||||
$ touch src/parse-gram.[ch]
|
||||
|
||||
Then proceed.
|
||||
|
||||
In case you wrecked your current copy of the parser, get back the previous
|
||||
version, compile bison, then force it to recreate the files:
|
||||
|
||||
$ git checkout HEAD^ src/parse-gram.[ch]
|
||||
$ make -C _build
|
||||
$ touch src/parse-gram.y
|
||||
$ make -C _build
|
||||
|
||||
|
||||
Test Suite
|
||||
==========
|
||||
|
||||
## make check
|
||||
Consume without moderation. It is composed of two kinds of tests: the
|
||||
examples, and the main test suite.
|
||||
|
||||
### The Examples
|
||||
In examples/, there is a number of ready-to-use examples (see
|
||||
examples/README.md). These examples have small test suites run by `make
|
||||
check`. The test results are in local `*.log` files (e.g.,
|
||||
`$build/examples/c/calc/calc.log`).
|
||||
|
||||
### The Main Test Suite
|
||||
The main test suite, in tests/, is written on top of GNU Autotest, which is
|
||||
part of Autoconf. Run `info autoconf 'Using Autotest'` to read the
|
||||
documentation, not only about how to write tests, but also where are the
|
||||
logs, how to read them etc.
|
||||
|
||||
The main test suite generates a log for each test (e.g.,
|
||||
`$build/tests/testsuite.dir/004/testsuite.log` for test #4), and a main log
|
||||
file in `$build/tests/testsuite.log`. The latter is meant for end users: it
|
||||
contains lots of details that should help diagnosing issues, including build
|
||||
issues. The per-test logs are more convenient when working locally.
|
||||
|
||||
#### TESTSUITEFLAGS
|
||||
To run just the main test suite, 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'
|
||||
|
||||
Actually, when using GNU Make, TESTSUITEFLAGS defaults to the -jN passed to
|
||||
it, so you may simply run
|
||||
|
||||
$ make check-local -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 get a list of all the tests (and their keywords for -k), run
|
||||
|
||||
$ ./tests/testsuite -l
|
||||
|
||||
To run a specific set of tests, use -k (for "keyword"). For example:
|
||||
|
||||
$ make check-local TESTSUITEFLAGS='-k c++'
|
||||
|
||||
Both can be combined.
|
||||
|
||||
$ make check-local TESTSUITEFLAGS='-j8 -k c++'
|
||||
|
||||
To rerun the tests that failed:
|
||||
|
||||
$ make recheck -j5
|
||||
|
||||
#### Updating the Expectations
|
||||
Sometimes some changes have a large impact on the test suite (e.g., when we
|
||||
added the `[-Wother]` part to all the warnings). Part of the update can be
|
||||
done with a crude tool: `build-aux/update-test`.
|
||||
|
||||
Once you ran the test suite, and therefore have many `testsuite.log` files,
|
||||
run, from the source tree:
|
||||
|
||||
$ ./build-aux/update-test $build/tests/testsuite.dir/*/testsuite.log
|
||||
|
||||
where `$build` would be your build tree. This will hopefully update most
|
||||
tests. Re-run the test suite. It might be interesting to run `update-test`
|
||||
again, since some early failures may stop latter tests from being run. Yet
|
||||
at some point, you'll have to fix remaining issues by hand...
|
||||
|
||||
|
||||
## Running Java parsers
|
||||
Use the `javaexec.sh` script. For instance to run the parser of test case
|
||||
504:
|
||||
|
||||
$ sh ./_build/javaexec.sh -cp ./_build/tests/testsuite.dir/504 Calc
|
||||
|
||||
## 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.
|
||||
|
||||
## gnulib
|
||||
To run tests on gnulib components (e.g., on bitset):
|
||||
|
||||
cd gnulib
|
||||
./gnulib-tool --test bitset-tests
|
||||
|
||||
possibly within a specified environment:
|
||||
|
||||
CC='gcc-mp-8 -fsanitize=undefined' ./gnulib-tool --test bitset-tests
|
||||
|
||||
To be able to run the tests several times, and to use symlinks instead of
|
||||
copies so that one can update the origin gnulib directory and immediately
|
||||
re-run the tests, run:
|
||||
|
||||
./gnulib-tool --symlink --create-test --dir=/tmp/gnutest bitset-tests
|
||||
cd /tmp/gnutest
|
||||
./configure -C CC='gcc-mp-8 -fsanitize=undefined' CFLAGS='-ggdb'
|
||||
make check
|
||||
|
||||
|
||||

||||

Subject: Re: Bison documentation?
|
||||
|
||||
The main difference between Bison and Yacc that I know of is that
|
||||
Bison supports the @N construction, which gives you access to
|
||||
the starting and ending line number and character number associated
|
||||
with any of the symbols in the current rule.
|
||||
|
||||
Also, Bison supports the command '%expect N' which says not to mention
|
||||
the conflicts if there are N shift/reduce conflicts and no reduce/reduce
|
||||
conflicts.
|
||||
|
||||
The differences in the algorithms stem mainly from the horrible
|
||||
kludges that Johnson had to perpetrate to make Yacc fit in a PDP-11.
|
||||
|
||||
Also, Bison uses a faster but less space-efficient encoding for the
|
||||
parse tables (see Corbett's PhD thesis from Berkeley, "Static
|
||||
Semantics in Compiler Error Recovery", June 1985, Report No. UCB/CSD
|
||||
85/251), and more modern technique for generating the lookahead sets.
|
||||
(See Frank DeRemer and Thomas Pennello, "Efficient Computation of
|
||||
LALR(1) Look-Ahead Sets", ACM Transactions on Programming Languages
|
||||
and Systems (TOPLAS) 4, 4 (October 1982), 615-649. Their
|
||||
technique is the standard one now.)

|

** Doc
|
||||
*** api.header.include
|
||||
|
||||
** Questions
|
||||
*** Java
|
||||
- Should i18n be part of the Lexer? Currently it's a static method of
|
||||
Lexer.
|
||||
|
||||
- is there a migration path that would allow to use TokenKinds in
|
||||
yylex?
|
||||
|
||||
- define the tokens as an enum too.
|
||||
|
||||
- promote YYEOF rather than EOF.
|
||||
|
||||
*** D
|
||||
- is there a way to attach yysymbol_name to the enum itself? As we did
|
||||
in Java.
|
||||
|
||||
- It would be better to have TokenKind as return value. Can we use
|
||||
reflection to support both output types?
|
||||
|
||||
** YYerror
|
||||
https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=blob;f=gettext-runtime/intl/plural.y;h=a712255af4f2f739c93336d4ff6556d932a426a5;hb=HEAD
|
||||
|
||||
should be updated to not use YYERRCODE. Returning an undef token is good
|
||||
enough.
|
||||
|
||||
** Java
|
||||
*** calc.at
|
||||
Stop hard-coding "Calc". Adjust local.at (look for FIXME).
|
||||
|
||||
* Bison 3.7
|
||||
** Counter example generation
|
||||
See https://github.com/akimd/bison/pull/15.
|
||||
|
||||
** Clean up
|
||||
Rename user_token_number for tokens as "code". It's not a "user number",
|
||||
it's the token code, and the user can control it, but this code always
|
||||
exists.
|
||||
|
||||
See also USER_NUMBER_UNDEFINED and NUMBER_UNDEFINED.
|
||||
|
||||
Rename endtoken as eoftoken.
|
||||
|
||||
Also do it in data/skeletons.
|
||||
|
||||
Don't rename in Bison 3.6 (it would be logical to do so) because that
|
||||
would probably create many conflicts in Vincent's work (see previous point).
|
||||
|
||||
** A dev warning for b4_
|
||||
Maybe we should check for m4_ and b4_ leaking out of the m4 processing, as
|
||||
Autoconf does. It would have caught overquotation issues.
|
||||
|
||||
** doc
|
||||
I feel it's ugly to use the GNU style to declare functions in the doc. It
|
||||
generates tons of white space in the page, and may contribute to bad page
|
||||
breaks.
|
||||
|
||||
** consistency
|
||||
token vs terminal, variable vs non terminal.
|
||||
|
||||
** api.token.raw
|
||||
The YYUNDEFTOK could be assigned a semantic value so that yyerror could be
|
||||
used to report invalid lexemes.
|
||||
|
||||
** push parsers
|
||||
Consider deprecating impure push parsers. They add a lot of complexity, for
|
||||
a bad feature. On the other hand, that would make it much harder to sit
|
||||
push parsers on top of pull parser. Which is currently not relevant, since
|
||||
push parsers are measurably slower.
|
||||
|
||||
** %define parse.error formatted
|
||||
How about pushing bistromathics' yyreport_syntax_error as another standard
|
||||
way to generate the error message, and leave to the user the task of
|
||||
providing the message formats? Currently in bistro, it reads:
|
||||
|
||||
const char *
|
||||
error_format_string (int argc)
|
||||
{
|
||||
switch (argc)
|
||||
{
|
||||
default: /* Avoid compiler warnings. */
|
||||
case 0: return _("%@: syntax error");
|
||||
case 1: return _("%@: syntax error: unexpected %u");
|
||||
// TRANSLATORS: '%@' is a location in a file, '%u' is an
|
||||
// "unexpected token", and '%0e', '%1e'... are expected tokens
|
||||
// at this point.
|
||||
//
|
||||
// For instance on the expression "1 + * 2", you'd get
|
||||
//
|
||||
// 1.5: syntax error: expected - or ( or number or function or variable before *
|
||||
case 2: return _("%@: syntax error: expected %0e before %u");
|
||||
case 3: return _("%@: syntax error: expected %0e or %1e before %u");
|
||||
case 4: return _("%@: syntax error: expected %0e or %1e or %2e before %u");
|
||||
case 5: return _("%@: syntax error: expected %0e or %1e or %2e or %3e before %u");
|
||||
case 6: return _("%@: syntax error: expected %0e or %1e or %2e or %3e or %4e before %u");
|
||||
case 7: return _("%@: syntax error: expected %0e or %1e or %2e or %3e or %4e or %5e before %u");
|
||||
case 8: return _("%@: syntax error: expected %0e or %1e or %2e or %3e or %4e or %5e or %6e before %u");
|
||||
}
|
||||
}
|
||||
|
||||
The message would have to be generated in a string, and pushed to yyerror.
|
||||
Which will be a pain in the neck in yacc.c.
|
||||
|
||||
If we want to do that, we should think very carefully about the syntax of
|
||||
the format string.

* Bison 3.8
|
||||
** Unit rules / Injection rules (Akim Demaille)
|
||||
Maybe we could expand unit rules (or "injections", see
|
||||
https://homepages.cwi.nl/~daybuild/daily-books/syntax/2-sdf/sdf.html), i.e.,
|
||||
transform
|
||||
|
||||
exp: arith | bool;
|
||||
arith: exp '+' exp;
|
||||
bool: exp '&' exp;
|
||||
|
||||
into
|
||||
|
||||
exp: exp '+' exp | exp '&' exp;
|
||||
|
||||
when there are no actions. This can significantly speed up some grammars.
|
||||
I can't find the papers. In particular the book 'LR parsing: Theory and
|
||||
Practice' is impossible to find, but according to 'Parsing Techniques: a
|
||||
Practical Guide', it includes information about this issue. Does anybody
|
||||
have it?
|
||||
|
||||
** clean up (Akim Demaille)
|
||||
Do not work on these items now, as I (Akim) have branches with a lot of
|
||||
changes in this area (hitting several files), and no desire to have to fix
|
||||
conflicts. Addressing these items will happen after my branches have been
|
||||
merged.
|
||||
|
||||
*** lalr.c
|
||||
Introduce a goto struct, and use it in place of from_state/to_state.
|
||||
Rename states1 as path, length as pathlen.
|
||||
Introduce inline functions for things such as nullable[*rp - ntokens]
|
||||
where we need to map from symbol number to nterm number.
|
||||
|
||||
There are probably a significant part of the relations management that
|
||||
should be migrated on top of a bitsetv.
|
||||
|
||||
*** closure
|
||||
It should probably take a "state*" instead of two arguments.
|
||||
|
||||
*** traces
|
||||
The "automaton" and "set" categories are not so useful. We should probably
|
||||
introduce lr(0) and lalr, just the way we have ielr categories. The
|
||||
"closure" function is too verbose, it should probably have its own category.
|
||||
|
||||
"set" can still be used for summariring the important sets. That would make
|
||||
tests easy to maintain.
|
||||
|
||||
*** complain.*
|
||||
Rename these guys as "diagnostics.*" (or "diagnose.*"), since that's the
|
||||
name they have in gcc, clang, etc. Likewise for the complain_* series of
|
||||
functions.
|
||||
|
||||
*** ritem
|
||||
states/nstates, rules/nrules, ..., ritem/nritems
|
||||
Fix the latter.
|
||||
|
||||
* Better error messages
|
||||
The users are not provided with enough tools to forge their error messages.
|
||||
See for instance "Is there an option to change the message produced by
|
||||
YYERROR_VERBOSE?" by Simon Sobisch, on bison-help.

|
||||
|
||||
* Modernization
|
||||
Fix data/skeletons/yacc.c so that it defines YYPTRDIFF_T properly for modern
|
||||
and older C++ compilers. Currently the code defaults to defining it to
|
||||
'long' for non-GCC compilers, but it should use the proper C++ magic to
|
||||
define it to the same type as the C ptrdiff_t type.
|
||||
|
||||
* Completion
|
||||
Several features are not available in all the backends.
|
||||
|
||||
- lac: D, Java (easy)
|
||||
- push parsers: glr.c, glr.cc, lalr1.cc (not very difficult)
|
||||
- token constructors: Java, C, D (a bit difficult)
|
||||
- glr: D, Java (super difficult)
|
||||
|
||||
* 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
|
||||
** Get rid of YYPRINT and b4_toknum
|
||||
Besides yytoknum is wrong when api.token.raw is defined.
|
||||
|
||||
** Better design for diagnostics
|
||||
The current implementation of diagnostics is ad hoc, it grew organically.
|
||||
It works as a series of calls to several functions, with dependency of the
|
||||
latter calls on the former. For instance:
|
||||
|
||||
complain (&sym->location,
|
||||
sym->content->status == needed ? complaint : Wother,
|
||||
_("symbol %s is used, but is not defined as a token"
|
||||
" and has no rules; did you mean %s?"),
|
||||
quote_n (0, sym->tag),
|
||||
quote_n (1, best->tag));
|
||||
if (feature_flag & feature_caret)
|
||||
location_caret_suggestion (sym->location, best->tag, stderr);
|
||||
|
||||
We should rewrite this in a more FP way:
|
||||
|
||||
1. build a rich structure that denotes the (complete) diagnostic.
|
||||
"Complete" in the sense that it also contains the suggestions, the list
|
||||
of possible matches, etc.
|
||||
|
||||
2. send this to the pretty-printing routine. The diagnostic structure
|
||||
should be sufficient so that we can generate all the 'format' of
|
||||
diagnostics, including the fixits.
|
||||
|
||||
If properly done, this diagnostic module can be detached from Bison and be
|
||||
put in gnulib. It could be used, for instance, for errors caught by
|
||||
xgettext.
|
||||
|
||||
There's certainly already something alike in GCC. At least that's the
|
||||
impression I get from reading the "-fdiagnostics-format=FORMAT" part of this
|
||||
page:
|
||||
|
||||
https://gcc.gnu.org/onlinedocs/gcc/Diagnostic-Message-Formatting-Options.html
|
||||
|

** Multiple start symbols
|

Would be very useful when parsing closely related languages. The idea is to

declare several start symbols, for instance

|
||||
%start stmt expr
|
||||
%%
|
||||
stmt: ...
|
||||
expr: ...
|
||||
|

and to generate parse(), parse_stmt() and parse_expr(). Technically, the
|
||||
above grammar would be transformed into
|
||||
|
||||
%start yy_start
|
||||
%token YY_START_STMT YY_START_EXPR
|
||||
%%
|
||||
yy_start: YY_START_STMT stmt | YY_START_EXPR expr
|
||||
|
||||
so that there are no new conflicts in the grammar (as would undoubtedly
|
||||
happen with yy_start: stmt | expr). Then adjust the skeletons so that this
|
||||
initial token (YY_START_STMT, YY_START_EXPR) be shifted first in the

||||
corresponding parse function.

addition to the $undefined value.

* 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

* 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.
|

# 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. This is
|
||||
used to define the token kind (i.e., the enum used by the return value of
|
||||
yylex).
|
||||
|
||||
- `tag`: string
|
||||
A human representation of the symbol. Can be 'foo', 'foo.id', '"foo"' etc.
|
||||
|
||||
- `user_number`: integer
|
||||
The code associated to the `id`.
|
||||
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.
|
||||
|
||||
- `kind`: string
|
||||
The symbol kind, i.e., the enumerator of this symbol (token or nonterminal)
|
||||
which is mapping to its `number`.
|
||||
|
||||
- `number`: integer
|
||||
The code associated to the `kind`.
|
||||
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
|
||||
- `printer_loc`: location
|
||||
If the symbol has a printer, everything about it.
|
||||
|
||||
- `has_destructor`, `destructor`, `destructor_file`, `destructor_line`, `destructor_loc`
|
||||
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.

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. */
|
||||
TokenKind 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 unions (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

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 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 appropriate
|
||||
value:
|
||||
make install prefix=z:/some/other/place

This directory contains examples of Bison grammar files, sorted per
|
||||
language.
|
||||
|
||||
Several of them come from the documentation, which should be installed
|
||||
together with Bison. The URLs are provided for convenience.
|
||||
|
||||
These examples come with a README and a Makefile. Not only can they be used
|
||||
to toy with Bison, they can also be starting points for your own grammars.
|
||||
|
||||
Please, be sure to read the C examples before looking at the other
|
||||
languages, as these examples are simpler.

# Examples in C++
|
||||
|
||||
This directory contains examples of Bison grammar files in C++.
|
||||
|
||||
You can run `make` to compile these examples. And `make clean` to tidy
|
||||
afterwards.
|
||||
|
||||
## simple.yy - Simple example in C++14
|
||||
A very simple example in C++, based on variants and symbol constructors.
|
||||
Variants allow to use any C++ type as semantic value type, and symbol
|
||||
constructors ensure consistency between declared token kind and effective
|
||||
semantic value.
|
||||
|
||||
Run as `./simple`.
|
||||
|
||||
Extracted from the documentation: "A Simple C++ Example".
|
||||
https://www.gnu.org/software/bison/manual/html_node/A-Simple-C_002b_002b-Example.html
|
||||
|
||||
## variant.yy - Self-contained example in C++98
|
||||
A variation of simple.yy, in C++98.
|
||||
|
||||
Run as `./variant`.
|
||||
|
||||
## variant-11.yy - Self-contained example in modern C++
|
||||
Another variation of simple.yy, closely related to the previous one, but
|
||||
exhibiting support for C++11's move semantics.
|
||||
|
||||
Run as `./variant` or `./variant NUMBER`.
|
||||
|
||||
## calc++ - A Complete C++ Example
|
||||
A fully featured C++ version of the canonical example for parsers: a
|
||||
calculator. Also uses Flex for the scanner.
|
||||
|
||||
Don't look at this example first: it is fully featured and can serve as a
|
||||
starting point for a clean parser in C++. The previous examples are better
|
||||
introductory examples, and the C examples are also useful introductory
|
||||
examples.

||||

||||

# calc++ - A Flex+Bison calculator
|
||||
|
||||
This directory contains calc++, a Bison grammar file in C++. If you never
|
||||
saw the traditional implementation in C, please first read
|
||||
examples/c/lexcalc, which can be seen as a C precursor of this example.
|
||||
|
||||
Read the corresponding chapter in the documentation: "A Complete C++
|
||||
Example". It is also available on line (maybe with a different version of
|
||||
Bison):
|
||||
https://www.gnu.org/software/bison/manual/html_node/A-Complete-C_002b_002b-Example.html
|
||||
|
||||
To use it, copy this directory into some work directory, and run `make` to
|
||||
compile the executable, and try it. It is a simple calculator which accepts
|
||||
several variable definitions, one per line, and then a single expression to
|
||||
evaluate.
|
||||
|
||||
The program calc++ expects the file to parse as argument; pass `-` to read
|
||||
the standard input (and then hit <Ctrl-d>, control-d, to end your input).
|
||||
|
||||
```
|
||||
$ ./calc++ -
|
||||
one := 1
|
||||
two := 2
|
||||
three := 3
|
||||
(one + two * three) * two * three
|
||||
<Ctrl-d>
|
||||
42
|
||||
```
|
||||
|
||||
You may pass `-p` to activate the parser debug traces, and `-s` to activate
|
||||
the scanner's.

# Examples in C
|
||||
|
||||
This directory contains simple examples of Bison grammar files in C.
|
||||
|
||||
Some of them come from the documentation, which should be installed together
|
||||
with Bison. The URLs are provided for convenience.
|
||||
|
||||
## rpcalc - Reverse Polish Notation Calculator
|
||||
The first example is that of a simple double-precision Reverse Polish
|
||||
Notation calculator (a calculator using postfix operators). This example
|
||||
provides a good starting point, since operator precedence is not an issue.
|
||||
|
||||
Extracted from the documentation: "Reverse Polish Notation Calculator"
|
||||
https://www.gnu.org/software/bison/manual/html_node/RPN-Calc.html
|
||||
|
||||
## calc - Simple Calculator
|
||||
This example is slightly more complex than rpcalc: it features infix
|
||||
operators (`1 + 2`, instead of `1 2 +` in rpcalc), but it does so using a
|
||||
unambiguous grammar of the arithmetic instead of using precedence
|
||||
directives (%left, etc.).
|
||||
|
||||
## mfcalc - Multi-Function Calculator
|
||||
A more complete C example: a multi-function calculator. More complex than
|
||||
the previous example. Using precedence directives to support infix
|
||||
operators.
|
||||
|
||||
Extracted from the documentation: "Multi-Function Calculator: mfcalc".

||||

## lexcalc - calculator with Flex and Bison
|
||||
The calculator with precedence directives and location tracking. It uses
|
||||
Flex to generate the scanner.
|
||||
|
||||
## reccalc - recursive calculator with Flex and Bison
|
||||
The example builds on top of the previous one to provide a reentrant parser.
|
||||
Such parsers can be called concurrently in different threads, or even
|
||||
recursively. To demonstrate this feature, expressions in parentheses are
|
||||
tokenized as strings, and then recursively parsed from the parser. So
|
||||
`(((1)+(2))*((3)+(4)))` uses eight parsers, with a depth of four.
|
||||
|
||||
## pushcalc - calculator implemented with a push parser
|
||||
All the previous examples are so called "pull parsers": the user invokes the
|
||||
parser once, which repeatedly calls the scanner until the input is drained.
|
||||
|
||||
This example demonstrates the "push parsers": the user calls the scanner to
|
||||
fetch the next token, passes it to the parser, and repeats the operation
|
||||
until the input is drained.
|
||||
|
||||
This example is a straightforward conversion of the 'calc' example to the
|
||||
push-parser model.
|
||||
|
||||
## bistromathic - all the bells and whistles
|
||||
This example demonstrates best practices when using Bison.
|
||||
- Its hand-written scanner tracks locations.
|
||||
- Its interface is pure.
|
||||
- It uses the `error` token to get error recovery.
|
||||
- Its interface is "incremental", well suited for interaction: it uses the
|
||||
push-parser API to feed the parser with the incoming tokens.
|
||||
- It features an interactive command line with completion based on the
|
||||
parser state, based on `yyexpected_tokens`.
|
||||
- It uses Bison's standard catalogue for internationalization of generated
|
||||
messages.
|
||||
- It uses a custom syntax error with location, lookahead correction and
|
||||
token internationalization.
|
||||
- It supports debug traces with semantic values.
|
||||
- It uses named references instead of the traditional $1, $2, etc.
