HACKING

--*- outline -*-
-
-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 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...
-
-- 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.
-
-- 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.).
-FIXME: `make alpha' is not maintained and is broken.  These
-instructions need to be replaced or removed.
-
-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.

+
+** If you incorporate a change from somebody on the net:
+First, if it is a large change, you must make sure they have signed

+** 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

 Obviously, if you are reading these notes, you did manage to check out

+Bison uses Git submodules: subscriptions to other Git repositories.
+In particular it uses gnulib, the GNU portability library.  To ask Git
+to perform the first checkout of the submodules, run
+
+       $ git submodule update --init
+
+Git submodule support is weak before versions 1.6 and later, you
+should probably upgrade Git if your version is older.
 
 The next step is to get other files needed to build, which are
 extracted from other source packages:
 
-	$ ./bootstrap
+        $ ./bootstrap
 
 And there you are!  Just
 
-	$ ./configure
+        $ ./configure
-	$ make
+        $ make
-	$ make check
+        $ make check
 
 At this point, there should be no difference between your local copy,
 and the master copy:
 
-	$ cvs diff
+        $ 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 reporitory 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.
+
+** 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.
+
+- Build with -DGNULIB_POSIXCHECK.  It suggests gnulib modules that can
+  fix portability issues.
+
+- 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.
+
+- Change tests/atlocal/CFLAGS to add your preferred options.  For
+  instance, `-traditional' to check that the parsers are K&R.  Note
+  that it does not make sense for glr.c, which should be ANSI,
+  but currently is actually GNU C, nor for lalr1.cc.
+
+
+* Release Procedure
+
+** Update the submodules.  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
+The version number, *and* the date of the release (including for
+betas).
+
+** Update ChangeLog
+Should have an entry similar to `Version 1.49b.'.
+
+** Tag the release
+Before Bison will build with the right version number, you must tag the release
+in git.  Do this after all other changes.  The command is similar to:
+
+  git tag -a v2.3b
+
+The log message can be simply:
+
+  Bison 2.3b
+
+** Push
+Once `make distcheck' passes, push your changes and the tag.
+`git push' without arguments will not push the tag.
+
+** make alpha
+FIXME: `make alpha' is not maintained and is broken.  These
+instructions need to be replaced or removed.
+
+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
+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.  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.
+
+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.bz2.
+
+** 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
+To generate a template announcement file:
+
+  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.
+
+** Bump the version number
+In configure.ac.  Run `make'.  So that developers don't accidentally add new
+items to the old NEWS entry, create a new empty NEWS entry something like:
+
+  Changes in version ?.? (????-??-??):
+
+Push these changes.

 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.

+
+- xml2dot.xsl

+             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

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