What to Hack =========================================================
|
||||
|
||||
You can hack whatever you want, thank GNU.
|
||||
|
||||
However, to see what others have indicated as their interest (and avoid
|
||||
potential wasteful duplication of effort), see file TODO. Note that
|
||||
the version you find may be out of date; a CVS checkout is recommended:
|
||||
see below for details (see also the files ANON-CVS and SNAPSHOTS).
|
||||
|
||||
It's also a good idea to join the guile-devel@gnu.org mailing list.
|
||||
See http://www.gnu.org/software/guile/mail/mail.html for more info.
|
||||
|
||||
|
||||
Hacking It Yourself ==================================================
|
||||
|
||||
When Guile is obtained from CVS, a few extra steps must be taken
|
||||
before the usual configure, make, make install. You will need to have
|
||||
up-to-date versions of the tools listed below, correctly installed.
|
||||
i.e., they must be found in the current PATH and not shadowed or
|
||||
otherwise broken by files left behind from other versions.
|
||||
|
||||
"up-to-date" means the latest released versions at the time that Guile
|
||||
was obtained from CVS. Sometimes older or newer versions will work.
|
||||
(See below for versions to avoid.)
|
||||
|
||||
Then you must run the autogen.sh script, as described below.
|
||||
|
||||
In case of problems, it may be worth getting a fresh copy of Guile
|
||||
from CVS: synchronisation problems have been known to occur
|
||||
occasionally.
|
||||
|
||||
The same procedure can be used to regenerate the files in released
|
||||
versions of Guile. In that case the headers of the original generated
|
||||
files (e.g., configure, Makefile.in, ltmain.sh) can be used to
|
||||
identify which tool versions may be required.
|
||||
|
||||
Autoconf --- a system for automatically generating `configure'
|
||||
scripts from templates which list the non-portable features a
|
||||
program would like to use. Available in
|
||||
"ftp://ftp.gnu.org/pub/gnu/autoconf"
|
||||
|
||||
Automake --- a system for automatically generating Makefiles that
|
||||
conform to the (rather Byzantine) GNU coding standards. The
|
||||
nice thing is that it takes care of hairy targets like 'make
|
||||
dist' and 'make distclean', and automatically generates
|
||||
Makefile dependencies. Automake is available in
|
||||
"ftp://ftp.gnu.org/pub/gnu/automake"
|
||||
|
||||
libtool --- a system for managing the zillion hairy options needed
|
||||
on various systems to produce shared libraries. Available in
|
||||
"ftp://ftp.gnu.org/pub/gnu/libtool"
|
||||
|
||||
gettext --- a system for rigging a program so that it can output its
|
||||
messages in the local tongue. Guile presently only exports
|
||||
the gettext functionality to Scheme, it does not use it
|
||||
itself.
|
||||
|
||||
flex --- a scanner generator. It's probably not essential to have the
|
||||
latest version.
|
||||
|
||||
One false move and you will be lost in a little maze of automatically
|
||||
generated files, all different.
|
||||
|
||||
Here is the authoritative list of tool/version/platform tuples that
|
||||
have been known to cause problems, and a short description of the problem.
|
||||
|
||||
- automake 1.4 adds extraneous rules to the top-level Makefile if
|
||||
you specify specific Makefiles to rebuild on the command line.
|
||||
|
||||
- automake 1.4-p4 (debian "1:1.4-p4-1.1") all platforms
|
||||
automake "include" facility does not recognize filenames w/ "-".
|
||||
|
||||
- libtool 1.4 uses acconfig.h, which is deprecated by newest autoconf
|
||||
(which constructs the equivalent through 3rd arg of AC_DEFINE forms).
|
||||
|
||||
- autoreconf from autoconf prior to 2.59 will run gettextize, which
|
||||
will mess up the Guile tree.
|
||||
|
||||
- (add here.)

||||

||||
|
||||
Sample GDB Initialization File=========================================
|
||||
|
||||
Here is a sample .gdbinit posted by Bill Schottstaedt (modified to
|
||||
use `set' instead of `call' in some places):
|
||||
|
||||
define gp
|
||||
set gdb_print($arg0)
|
||||
print gdb_output
|
||||
end
|
||||
document gp
|
||||
Executes (object->string arg)
|
||||
end
|
||||
|
||||
define ge
|
||||
call gdb_read($arg0)
|
||||
call gdb_eval(gdb_result)
|
||||
set gdb_print(gdb_result)
|
||||
print gdb_output
|
||||
end
|
||||
document ge
|
||||
Executes (print (eval (read arg))): ge "(+ 1 2)" => 3
|
||||
end
|
||||
|
||||
define gh
|
||||
call g_help(scm_str2symbol($arg0), 20)
|
||||
set gdb_print($1)
|
||||
print gdb_output
|
||||
end
|
||||
document gh
|
||||
Prints help string for arg: gh "enved-target"
|
||||
end
|
||||
|
||||
Bill further writes:
|
||||
|
||||
so in gdb if you see something useless like:
|
||||
|
||||
#32 0x081ae8f4 in scm_primitive_load (filename=1112137128) at load.c:129
|
||||
|
||||
You can get the file name with gp:
|
||||
|
||||
(gdb) gp 1112137128
|
||||
$1 = 0x40853fac "\"/home/bil/test/share/guile/1.5.0/ice-9/session.scm\""
|
||||
|
||||
|
||||
Contributing Your Changes ============================================
|
||||
|
||||
- If you have put together a change that meets the coding standards
|
||||
described below, we encourage you to submit it to Guile. The best
|
||||
place to post it is guile-devel@gnu.org. Please don't send it
|
||||
directly to me; I often don't have time to look things over. If you
|
||||
have tested your change, then you don't need to be shy.
|
||||
|
||||
- Please submit patches using either context or unified diffs (diff -c
|
||||
or diff -u). Don't include a patch for ChangeLog; such patches don't
|
||||
apply cleanly, since we've probably changed the top of ChangeLog too.
|
||||
Instead, provide the unaltered text at the top of your patch.
|
||||
|
||||
- For proper credit, also make sure you update the AUTHORS file
|
||||
(for new files for which you've assigned copyright to the FSF), or
|
||||
the THANKS file (for everything else).
|
||||
|
||||
Please don't include patches for generated files like configure,
|
||||
aclocal.m4, or any Makefile.in. Such patches are often large, and
|
||||
we're just going to regenerate those files anyway.
|
||||
|
||||
|
||||
CVS conventions ======================================================
|
||||
|
||||
- We use CVS to manage the Guile sources. The repository lives on
|
||||
subversions.gnu.org, in /cvs; you will need an
|
||||
account on that machine to access the repository. Also, for security
|
||||
reasons, subversions presently only supports CVS connections via the SSH
|
||||
protocol, so you must first install the SSH client. Then, you should
|
||||
set your CVS_RSH environment variable to ssh, and use the following as
|
||||
your CVS root:
|
||||
|
||||
:ext:USER@subversions.gnu.org:/cvs
|
||||
|
||||
Either set your CVSROOT environment variable to that, or give it as
|
||||
the value of the global -d option to CVS when you check out a working
|
||||
directory.
|
||||
|
||||
For more information on SSH, see http://www.openssh.com.
|
||||
|
||||
The Guile sources live in several modules:
|
||||
|
||||
- guile-core --- the interpreter, QuickThreads, and ice-9
|
||||
- guile-tcltk --- the Guile/Tk interface
|
||||
- guile-tk --- the new Guile/Tk interface, based on STk's modified Tk
|
||||
- guile-rgx-ctax --- the Guile/Rx interface, and the ctax implementation
|
||||
- guile-scsh --- the port of SCSH to guile, talk to Gary Houston
|
||||
- guile-www --- A Guile module for making HTTP requests.
|
||||
- guile-statprof --- an experimental statistical profiler.
|
||||
|
||||
There is a mailing list for CVS commit messages; see README for details.
|
||||
|
||||
- The guile-core tree is now versioned similarly to the Linux kernel.
|
||||
Guile now always uses three numbers to represent the version,
|
||||
i.e. "1.6.5". The first number, 1, is the major version number, the
|
||||
second number, 6, is the minor version number, and the third number,
|
||||
5, is the micro version number. Changes in major version number
|
||||
indicate major changes in Guile.
|
||||
|
||||
Minor version numbers that are even denote stable releases, and odd
|
||||
minor version numbers denote development versions (which may be
|
||||
unstable). The micro version number indicates a minor sub-revision of
|
||||
a given MAJOR.MINOR release.
|
||||
|
||||
- A default CVS checkout will get the current unstable development
|
||||
tree. However, for each stable release, a CVS branch is created so
|
||||
that release (and ongoing maintenance) of the stable version can
|
||||
proceed independent of the development of the next unstable version.
|
||||
To check out a particular stable branch, you just need to specify "-r
|
||||
branch_release-X-Y" to your CVS checkout command (or to any update).
|
||||
For example, if you wanted to check out the 1.6 stable branch, you
|
||||
would specify "-r branch_release-1-6".
|
||||
|
||||
So, for example, during a normal development cycle, work will proceed
|
||||
on an unstable version, say 1.5.X, until it is decided that it's time
|
||||
for a stable release. At that point, a branch named
|
||||
branch_release-1-6 will be created, and the version numbers on the
|
||||
HEAD of the CVS tree (the trunk, i.e. what you get by default), will
|
||||
be changed to reflect the new unstable version 1.7.X. Then unstable
|
||||
development will proceed on the unstable version, while the stable
|
||||
1.5.X branch is fixed up for the eventual 1.6.0 release.
|
||||
|
||||
Anytime you want to yank an existing checked out tree to the stable
|
||||
branch, you can run a command like this:
|
||||
|
||||
cvs -z3 update -r branch_release-1-6 -Pd
|
||||
|
||||
This will yank the working directory over on to the stable release
|
||||
branch. Note that this directory will track that branch from then on
|
||||
unless you do something to yank it back to the main (unstable) trunk.
|
||||
|
||||
To go back to the unstable branch, you can use
|
||||
|
||||
cvs -z3 update -A -Pd
|
||||
|
||||
Note that in either case, you should probably make sure you've
|
||||
commited or removed all local changes before running the commands or
|
||||
you're likely to have some unexpected results.
|
||||
|
||||
Finally note that one approach, should you need to work on both
|
||||
branches, is to keep two trees checked out, one stable, the other
|
||||
unstable and you can work in whichever is appropriate.
|
||||
|
||||
To save some initial bandwidth, you can check out either the stable
|
||||
tree or the unstable tree, and then do something like this:
|
||||
|
||||
cp -a core-unstable core-1.5
|
||||
cd core-1.5
|
||||
cvs -z3 update -r branch_release-1-6 -Pd
|
||||
|
||||
- The stable and unstable CVS trees are distinct, and no changes will
|
||||
automatically propagate between them. If you make changes that need
|
||||
to show up both places, you'll need to apply the changes both places.
|
||||
You *might* be able to do this with a cvs command, but often you'll
|
||||
probably need to apply the changes by hand or risk migrating
|
||||
superfluous modifications between the two versions. This is
|
||||
particularly important when moving a change from the unstable branch
|
||||
to the stable branch.
|
||||
|
||||
- In general, please don't be adventurous with the stable branch. We
|
||||
mostly want bugfixes, documentation improvements, build improvements,
|
||||
etc., though exceptions will doubtless exist.
|
||||
|
||||
- There are a few CVS tagging conventions which follow the Scheme
|
||||
convention that dashes are used to separate words within a single
|
||||
symbol, and so dashes bind more tightly than underscores. This means
|
||||
that foo-bar_baz-bax indicates that foo-bar is somehow separate from
|
||||
baz-bax. The conventions are as follows:
|
||||
|
||||
Branch root tags:
|
||||
-----------------
|
||||
anytime just before you create a branch it's a good
|
||||
idea to create a normal tag so that you can refer to the branch point
|
||||
on the main trunk as well as on the branch. So please use a tag of
|
||||
the form
|
||||
|
||||
branch-root-release-1-X
|
||||
|
||||
or more generally, for other non-release branches:
|
||||
|
||||
branch-root_FOO
|
||||
|
||||
Branch tags:
|
||||
------------
|
||||
for the branch tag itself please use
|
||||
|
||||
branch_release-1-6
|
||||
|
||||
or more generally, for other non-release branches:
|
||||
|
||||
branch_FOO
|
||||
|
||||
Merge tags:
|
||||
-----------
|
||||
Whenever you're merging a branch back into the trunk (or into another
|
||||
branch repeatedly) you need to tag the branch each time you merge. If
|
||||
you don't do that, you won't be able to merge repeatedly without
|
||||
possibly tedious conflicts. For those tags, we suggest:
|
||||
|
||||
branch-merge_SOME-FOO_to_SOME-BAR_1
|
||||
branch-merge_SOME-FOO_to_SOME-BAR_2
|
||||
..
|
||||
|
||||
As an example, SOME-BAR might be trunk, or even perhaps another branch
|
||||
like branch-mvo-super-fixes :>
|
||||
|
||||
More mundanely, you might have
|
||||
|
||||
branch-merge_release-1-6_to_trunk_1
|
||||
|
||||
(Merging the stable branch to the trunk like this
|
||||
will probably be much more common, when it happens, than the
|
||||
reverse for the reasons mentioned above.
|
||||
|
||||
Release tags:
|
||||
-------------
|
||||
When releasing a new version of guile, please use:
|
||||
|
||||
release_X-Y-Z
|
||||
|
||||
i.e.
|
||||
|
||||
release_1-6-0
|
||||
|
||||
- If you hack on a stable branch, please apply any relevant patches or
|
||||
fixes to the current unstable version (the main CVS trunk) as well.
|
||||
Similarly, please back-port any important fixes to the unstable CVS
|
||||
tree to the current stable branch.
|
||||
|
||||
- We check Makefile.am and configure.in files into CVS, but the
|
||||
"autogen.sh" script must be run from the top-level to generate the
|
||||
actual "configure" script that then must be run to create the various
|
||||
Makefile-s to build guile. The general rule is that you should be able
|
||||
to check out a working directory of Guile from CVS, and then type
|
||||
"./autogen.sh", then "configure", and finally "make". No
|
||||
automatically generated files should be checked into the CVS
|
||||
repository.
|
||||
|
||||
- The .cvsignore file is contained in the repository, to provide a
|
||||
reasonable list of auto-generated files that should not be checked in.
|
||||
This, however, prohibits one from having local additions to the
|
||||
.cvsignore file (yes, you can modify it and never check it in, but
|
||||
that doesn't seem to be a good solution to me). To get around this
|
||||
problem, you might want to patch your cvs program so that it uses a
|
||||
.cvsignore-local file (say) instead of the one from the repository. A
|
||||
patch for this can be found at the very end of this file.
|
||||
|
||||
- (Automake 1.4 only) Be sure to run automake at the top of the tree
|
||||
with no arguments. Do not use `automake Makefile' to regenerate
|
||||
specific Makefile.in files, and do not trust the Makefile rules to
|
||||
rebuild them when they are out of date. Automake 1.4 will add
|
||||
extraneous rules to the top-level Makefile if you specify specific
|
||||
Makefiles to rebuild on the command line. Running the command
|
||||
`autoreconf --force' should take care of everything correctly.
|
||||
|
||||
- Make sure your changes compile and work, at least on your own
|
||||
machine, before checking them into the main branch of the Guile
|
||||
repository. A good way for testing this is to run "make distcheck".
|
||||
If you really need to check in untested changes, make a branch.
|
||||
|
||||
- Include each log entry in both the ChangeLog and in the CVS logs.
|
||||
If you're using Emacs, the pcl-cvs interface to CVS has features to
|
||||
make this easier; it checks the ChangeLog, and generates good default
|
||||
CVS log entries from that.
|
||||
|
||||
|
||||
Coding standards =====================================================
|
||||
|
||||
- Before contributing larger amounts of code to Guile, please read the
|
||||
documents in `guile-core/devel/policy' in the CVS source tree.
|
||||
|
||||
- As for any part of Project GNU, changes to Guile should follow the
|
||||
GNU coding standards. The standards are available via anonymous FTP
|
||||
from prep.ai.mit.edu, as /pub/gnu/standards/standards.texi and
|
||||
make-stds.texi.
|
||||
|
||||
- The Guile tree should compile without warnings under the following
|
||||
GCC switches, which are the default in the current configure script:
|
||||
|
||||
-O2 -Wall -Wpointer-arith -Wmissing-prototypes
|
||||
|
||||
To make sure of this, you can use the --enable-error-on-warning option
|
||||
to configure. This option will make GCC fail if it hits a warning.
|
||||
|
||||
Note that the warnings generated vary from one version of GCC to the
|
||||
next, and from one architecture to the next (apparently). To provide
|
||||
a concrete common standard, Guile should compile without warnings from
|
||||
GCC 2.7.2.3 in a Red Hat 5.2 i386 Linux machine. Furthermore, each
|
||||
developer should pursue any additional warnings noted by on their
|
||||
compiler. This means that people using more stringent compilers will
|
||||
have more work to do, and assures that everyone won't switch to the
|
||||
most lenient compiler they can find. :)
|
||||
|
||||
Note also that EGCS (as of November 3 1998) doesn't handle the
|
||||
`noreturn' attribute properly, so it doesn't understand that functions
|
||||
like scm_error won't return. This may lead to some silly warnings
|
||||
about uninitialized variables. You should look into these warnings to
|
||||
make sure they are indeed spurious, but you needn't correct warnings
|
||||
caused by this EGCS bug.
|
||||
|
||||
- If you add code which uses functions or other features that are not
|
||||
entirely portable, please make sure the rest of Guile will still
|
||||
function properly on systems where they are missing. This usually
|
||||
entails adding a test to configure.in, and then adding #ifdefs to your
|
||||
code to disable it if the system's features are missing.
|
||||
|
||||
- The normal way of removing a function, macro or variable is to mark
|
||||
it as "deprecated", keep it for a while, and remove it in a later
|
||||
release. If a function or macro is marked as "deprecated" it
|
||||
indicates that people shouldn't use it in new programs, and should try
|
||||
to remove it in old. Make sure that an alternative exists unless it
|
||||
is our purpose to remove functionality. Don't deprecate definitions
|
||||
if it is unclear when they will be removed. (This is to ensure that a
|
||||
valid way of implementing some functionality always exists.)
|
||||
|
||||
When deprecating a definition, always follow this procedure:
|
||||
|
||||
1. Mark the definition using
|
||||
|
||||
#if (SCM_DEBUG_DEPRECATED == 0)
|
||||
...
|
||||
#endif
|
||||
|
||||
or, for Scheme code, wrap it using
|
||||
|
||||
(begin-deprecated
|
||||
...)
|
||||
|
||||
2. Make the deprecated code issue a warning when it is used, by using
|
||||
scm_c_issue_deprecation_warning (in C) or issue-deprecation-warning
|
||||
(in Scheme).
|
||||
|
||||
3. Write a comment at the definition explaining how a programmer can
|
||||
manage without the deprecated definition.
|
||||
|
||||
4. Add an entry that the definition has been deprecated in NEWS and
|
||||
explain what do do instead.
|
||||
|
||||
5. In file TODO, there is a list of releases with reminders about what
|
||||
to do at each release. Add a reminder about the removal of the
|
||||
deprecated defintion at the appropriate release.
|
||||
|
||||
- Please write log entries for functions written in C under the
|
||||
functions' C names, and write log entries for functions written in
|
||||
Scheme under the functions' Scheme names. Please don't do this:
|
||||
|
||||
* procs.c, procs.h (procedure-documentation): Moved from eval.c.
|
||||
|
||||
Entries like this make it harder to search the ChangeLogs, because you
|
||||
can never tell which name the entry will refer to. Instead, write this:
|
||||
|
||||
* procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
|
||||
|
||||
Changes like adding this line are special:
|
||||
|
||||
SCM_PROC (s_map_in_order, "map-in-order", 2, 0, 1, scm_map);
|
||||
|
||||
Since the change here is about the name itself --- we're adding a new
|
||||
alias for scm_map that guarantees the order in which we process list
|
||||
elements, but we're not changing scm_map at all --- it's appropriate
|
||||
to use the Scheme name in the log entry.
|
||||
|
||||
- There's no need to keep a change log for a ChangeLog file. For any
|
||||
other kind of file (including documentation, since our documentation
|
||||
is indeed precisely engineered -- we surpass GNU standards here), add
|
||||
an appropriate ChangeLog entry when you change it. Simple!
|
||||
|
||||
- Make sure you have papers from people before integrating their
|
||||
changes or contributions. This is very frustrating, but very
|
||||
important to do right. From maintain.texi, "Information for
|
||||
Maintainers of GNU Software":
|
||||
|
||||
When incorporating changes from other people, make sure to follow the
|
||||
correct procedures. Doing this ensures that the FSF has the legal
|
||||
right to distribute and defend GNU software.
|
||||
|
||||
For the sake of registering the copyright on later versions ofthe
|
||||
software you need to keep track of each person who makes significant
|
||||
changes. A change of ten lines or so, or a few such changes, in a
|
||||
large program is not significant.
|
||||
|
||||
*Before* incorporating significant changes, make sure that the person
|
||||
has signed copyright papers, and that the Free Software Foundation has
|
||||
received them.
|
||||
|
||||
If you receive contributions you want to use from someone, let me know
|
||||
and I'll take care of the administrivia. Put the contributions aside
|
||||
until we have the necessary papers.
|
||||
|
||||
Once you accept a contribution, be sure to keep the files AUTHORS and
|
||||
THANKS uptodate.
|
||||
|
||||
- When you make substantial changes to a file, add the current year to
|
||||
the list of years in the copyright notice at the top of the file.
|
||||
|
||||
- When you get bug reports or patches from people, be sure to list
|
||||
them in THANKS.

||||
|
||||
Naming conventions =================================================
|
||||
|
||||
We use certain naming conventions to structure the considerable number
|
||||
of global identifiers. All identifiers should be either all lower
|
||||
case or all upper case. Syllables are separated by underscores `_'.
|
||||
All non-static identifiers should start with scm_ or SCM_. Then might
|
||||
follow zero or more syllables giving the category of the identifier.
|
||||
The currently used category identifiers are
|
||||
|
||||
t - type name
|
||||
|
||||
c,C - something with a interface suited for C use. This is used
|
||||
to name functions that behave like Scheme primitives but
|
||||
have a more C friendly calling convention.
|
||||
|
||||
i,I - internal to libguile. It is global, but not considered part
|
||||
of the libguile API.
|
||||
|
||||
f - a SCM variable pointing to a Scheme function object.
|
||||
|
||||
F - a bit mask for a flag.
|
||||
|
||||
m - a macro transformer procedure
|
||||
|
||||
n,N - a count of something
|
||||
|
||||
s - a constant C string
|
||||
|
||||
k - a SCM variable pointing to a keyword.
|
||||
|
||||
sym - a SCM variable pointing to a symbol.
|
||||
|
||||
var - a SCM variable pointing to a variable object.
|
||||
|
||||
The follwing syllables also have a technical meaning:
|
||||
|
||||
str - this denotes a zero terminated C string
|
||||
|
||||
mem - a C string with an explicit count
|
||||
|
||||
|
||||
See also the file `devel/names.text'.
|
||||
|
||||
|
||||
Helpful hints ========================================================
|
||||
|
||||
- [From Mikael Djurfeldt] When working on the Guile internals, it is
|
||||
quite often practical to implement a scheme-level procedure which
|
||||
helps you examine the feature you're working on.
|
||||
|
||||
Examples of such procedures are: pt-size, debug-hand and
|
||||
current-pstate.
|
||||
|
||||
I've now put #ifdef GUILE_DEBUG around all such procedures, so that
|
||||
they are not compiled into the "normal" Guile library. Please do the
|
||||
same when you add new procedures/C functions for debugging purpose.
|
||||
|
||||
You can define the GUILE_DEBUG flag by passing --enable-guile-debug to
|
||||
the configure script.
|
||||
|
||||
- You'll see uses of the macro SCM_P scattered throughout the code;
|
||||
those are vestiges of a time when Guile was meant to compile on
|
||||
pre-ANSI compilers. Guile now requires ANSI C, so when you write new
|
||||
functions, feel free to use ANSI declarations, and please provide
|
||||
prototypes for everything. You don't need to use SCM_P in new code.
|
||||
|
||||
|
||||
Jim Blandy, and others
|
||||
|
||||
|
||||
