@node Writing modules
@chapter Writing modules

This chapter explains how to write modules of your own, either to
extend Gnulib for your own package (@pxref{Extending Gnulib}), or for
inclusion in gnulib proper.

The guidelines in this chapter do not necessarily need to be followed for
using @code{gnulib-tool}.  They merely represent a set of good practices.
Following them will result in a good structure of your modules and in
consistency with gnulib.

@node Source code files
@section Source code files

Every API (C functions or variables) provided should be declared in a header
file (.h file) and implemented in one or more implementation files (.c files).
The separation has the effect that users of your module need to read only
the contents of the .h file and the module description in order to understand
what the module is about and how to use it---not the entire implementation.
Furthermore, users of your module don't need to repeat the declarations of
the functions in their code, and are likely to receive notification through
compiler errors if you make incompatible changes to the API (like, adding a
parameter or changing the return type of a function).


@node Header files
@section Header files

The .h file should declare the C functions and variables that the module
provides.

The .h file should be stand-alone.  That is, it does not require other .h files
to be included before.  Rather, it includes all necessary .h files by itself.

@cindex double inclusion of header files
@cindex header file include protection
It is a tradition to use CPP tricks to avoid parsing the same header
file more than once, which might cause warnings.  The trick is to wrap
the content of the header file (say, @file{foo.h}) in a block, as in:

@example
#ifndef FOO_H
# define FOO_H
...
body of header file goes here
...
#endif /* FOO_H */
@end example

Whether to use @code{FOO_H} or @code{_FOO_H} is a matter of taste and
style.  The C99 and C11 standards reserve all identifiers that begin with an
underscore and either an uppercase letter or another underscore, for
any use.  Thus, in theory, an application might not safely assume that
@code{_FOO_H} has not already been defined by a library.  On the other
hand, using @code{FOO_H} will likely lead the higher risk of
collisions with other symbols (e.g., @code{KEY_H}, @code{XK_H}, @code{BPF_H},
which are CPP macro constants, or @code{COFF_LONG_H}, which is a CPP
macro function).  Your preference may depend on whether you consider
the header file under discussion as part of the application (which has
its own namespace for CPP symbols) or a supporting library (that
shouldn't interfere with the application's CPP symbol namespace).

@cindex C++ header files
@cindex Header files and C++
Adapting C header files for use in C++ applications can use another
CPP trick, as in:

@example
# ifdef __cplusplus
extern "C"
@{
# endif
...
body of header file goes here
...
# ifdef __cplusplus
@}
# endif
@end example

The idea here is that @code{__cplusplus} is defined only by C++
implementations, which will wrap the header file in an @samp{extern "C"}
block.  Again, whether to use this trick is a matter of taste and
style.  While the above can be seen as harmless, it could be argued
that the header file is written in C, and any C++ application using it
should explicitly use the @samp{extern "C"} block itself.  Your
preference might depend on whether you consider the API exported by
your header file as something available for C programs only, or for C
and C++ programs alike.

Note that putting a @code{#include} in an @code{extern "C" @{ ... @}}
block yields a syntax error in C++ mode on some platforms (e.g., glibc
systems with g++ v3.3 to v4.2, AIX).  For this reason, it
is recommended to place the @code{#include} before the @code{extern
"C"} block.

@node Implementation files
@section Implementation files

The .c file or files implement the functions and variables declared in the
.h file.

@subheading Include ordering

Every implementation file must start with @samp{#include <config.h>}.
This is necessary for activating the preprocessor macros that are defined
on behalf of the Autoconf macros.  Some of these preprocessor macros,
such as @code{_GNU_SOURCE}, would have no effect if defined after a system
header file has already been included.

Then comes the @samp{#include "..."} specifying the header file that is
being implemented.  Putting this right after @samp{#include <config.h>}
has the effect that it verifies that the header file is self-contained.

Then come the system and application headers. It is customary to put all the
system headers before all application headers, so as to minimize the risk
that a preprocessor macro defined in an application header confuses the system
headers on some platforms.

In summary:

@itemize
@item
First comes #include <config.h>.
@item
Second comes the #include "..." specifying the module being implemented.
@item
Then come all the #include <...> of system or system-replacement headers,
in arbitrary order.
@item
Then come all the #include "..." of gnulib and application headers, in
arbitrary order.
@end itemize


@node Specification
@section Specification

The specification of a function should answer at least the following
questions:
@itemize
@item
What is the purpose of the function?
@item
What are the arguments?
@item
What is the return value?
@item
What happens in case of failure? (Exit? A specific return value? Errno set?)
@item
Memory allocation policy: If pointers to memory are returned, are they freshly
allocated and supposed to be freed by the caller?
@end itemize

@cindex specification
@cindex comments describing functions
@cindex describing functions, locating
Where to put the specification describing exported functions? Three practices
are used in gnulib:

@itemize
@item
The specification can be as comments in the header file, just above the
function declaration.
@item
The specification can be as comments in the implementation file, just above
the function definition.
@item
The specification can be in texinfo format, so that it gets included in the
gnulib manual.
@end itemize

In any case, the specification should appear in just one place, unless you can
ensure that the multiple copies will always remain identical.

The advantage of putting it in the header file is that the user only has to
read the include file normally never needs to peek into the implementation
file(s).

The advantage of putting it in the implementation file is that when reviewing
or changing the implementation, you have both elements side by side.

The advantage of texinfo formatted documentation is that it is easily
published in HTML or Info format.

Currently (as of 2020), 70% of gnulib uses the first practice, 25% of
gnulib uses the second practice, and a small minority uses the texinfo
practice.


@node Module description
@section Module description

For the module description, you can start from an existing module's
description, or from a blank one: @file{module/TEMPLATE} for a normal module,
or @file{module/TEMPLATE-TESTS} for a unit test module.  Some more fields
are possible but rarely used.  Use @file{module/TEMPLATE-EXTENDED} if you
want to use one of them.

Module descriptions have the following fields.  Absent fields are equivalent
to fields with empty contents.

@table @asis
@item Description
This field should contain a concise description of the module's functionality.
One sentence is enough.  For example, if it defines a single function
@samp{frob}, the description can be @samp{frob() function: frobnication.}
Gnulib's documentation generator will automatically convert the first part
to a hyperlink when it has this form.

@item Status
This field is either empty/absent, or contains the word @samp{obsolete}.  In
the latter case, @command{gnulib-tool} will, unless the option
@code{--with-obsolete} is given, omit it when it used as a dependency.  It is
good practice to also notify the user about an obsolete module.  This is done
by putting into the @samp{Notice} section (see below) text like
@samp{This module is obsolete.}

@item Notice
This field contains text that @command{gnulib-tool} will show to the user
when the module is used.  This can be a status indicator like
@samp{This module is obsolete.} or additional advice.  Do not abuse this
field.

@item Applicability
This field is either empty/absent, or contains the word @samp{all}.  It
describes to which @code{Makefile.am} the module is applied.  By default,
a normal module is applied to @code{@var{source_base}/Makefile.am}
(normally @code{lib/Makefile.am}), whereas a module ending in @code{-tests}
is applied to @code{@var{tests_base}/Makefile.am} (normally
@code{tests/Makefile.am}).  If this field is @samp{all}, it is applied to
both @code{Makefile.am}s.  This is useful for modules which provide
Makefile.am macros rather than compiled source code.

@item Usable-in-testdir
This field should contain @samp{no} if the module cannot be used in a
test directory created with @code{gnulib-tool --create-testdir}.

@item Files
This field contains a newline separated list of the files that are part of
the module.  @code{gnulib-tool} copies these files into the package that
uses the module.

This list is typically ordered by importance: First comes the header file,
then the implementation files, then other files.

It is possible to have the same file mentioned in multiple modules.  That is,
if the maintainers of that module agree on the purpose and future of said
file.

@item Depends-on
This field contains a newline separated list of the modules that are required
for the proper working of this module.  @code{gnulib-tool} includes each
required module automatically, unless it is specified with option
@code{--avoid} or it is marked as obsolete and the option
@code{--with-obsolete} is not given.

A test modules @code{foo-tests} implicitly depends on the corresponding non-test
module @code{foo}.  @code{foo} implicitly depends on @code{foo-tests} if the
latter exists and if the option @code{--with-tests} has been given.

Tests modules can depend on non-tests modules.  Non-tests modules should not
depend on tests modules. (Recall that tests modules are built in a separate
directory.)

Each listed required module may be declared a conditional dependency.  This
is indicated by placing the condition for the dependency on the same line,
enclosed in brackets, after the name of the required module.  The condition
is a shell expression that is run after the module's @code{configure.ac}
statements.  For example:
@smallexample
strtoull   [test $ac_cv_func_strtoumax = no]
@end smallexample

Lines starting with @code{#} are recognized as comments and are ignored.

@item configure.ac-early
This field contains @file{configure.ac} stuff (Autoconf macro invocations and
shell statements) that are logically placed early in the @file{configure.ac}
file: right after the @code{AC_PROG_CC} invocation.  This section is adequate
for statements that modify @code{CPPFLAGS}, as these can affect the results of
other Autoconf macros.

@item configure.ac
This field contains @file{configure.ac} stuff (Autoconf macro invocations and
shell statements).

It is forbidden to add items to the @code{CPPFLAGS} variable here, other than
temporarily, as these could affect the results of other Autoconf macros.

We avoid adding items to the @code{LIBS} variable, other than temporarily.
Instead, the module can export an Autoconf-substituted variable that contains
link options.  The user of the module can then decide to which executables
to apply which link options.  Recall that a package can build executables of
different kinds and purposes; having all executables link against all
libraries is inappropriate.

If the statements in this section grow larger than a couple of lines, we
recommend moving them to a @code{.m4} file of their own.

@item Makefile.am
This field contains @code{Makefile.am} statements.  Variables like
@code{lib_SOURCES} are transformed to match the name of the library
being built in that directory.  For example, @code{lib_SOURCES} may become
@code{libgnu_a_SOURCES} (for a plain library) or @code{libgnu_la_SOURCES}
(for a libtool library).  Therefore, the normal way of having an
implementation file @code{lib/foo.c} compiled unconditionally is to write
@smallexample
lib_SOURCES += foo.c
@end smallexample

@item Include
This field contains the preprocessor statements that users of the module
need to add to their source code files.  Typically it's a single include
statement.  A shorthand is allowed: You don't need to write the word
``#include'', just the name of the include file in the way it will appear
in an include statement.  Example:
@smallexample
"foo.h"
@end smallexample

@item Link
This field contains the set of libraries that are needed when linking
libraries or executables that use this module.  Often this will be
written as a reference to a Makefile variable.  Please write them
one per line, so that @command{gnulib-tool} can remove duplicates
when presenting a summary to the user.
Example:
@smallexample
$(POW_LIBM)
$(LTLIBICONV) when linking with libtool, $(LIBICONV) otherwise
@end smallexample
When this field is omitted, it defaults to the union of the @code{Link}
field of the dependencies.

@item License
This field specifies the license that governs the source code parts of
this module.  See @ref{Copyright} for details.  Be sure to place, in every
source code file, a copyright notice and the appropriate license notice,
taken from the @file{etc/license-notices/} directory.

@item Maintainer
This field specifies the persons who have a definitive say about proposed
changes to this module.  You don't need to mention email addresses here:
they can be inferred from the @code{ChangeLog} file.

Please put at least one person here.  We don't like unmaintained modules.
@end table


@node Autoconf macros
@section Autoconf macros

For a module @code{foo}, an Autoconf macro file @file{m4/foo.m4} is typically
created when the Autoconf macro invocations for the module are longer than
one or two lines.

The name of the main entry point into this Autoconf macro file is typically
@code{gl_FOO}.  For modules outside Gnulib that are not likely to be moved
into Gnulib, please use a prefix specific to your package: @code{gt_} for
GNU gettext, @code{cu_} for GNU coreutils, etc.

For modules that define a function @code{foo}, the entry point is called
@code{gl_FUNC_FOO} instead of @code{gl_FOO}.  For modules that provide a
header file with multiple functions, say @code{foo.h}, the entry point is
called @code{gl_FOO_H} or @code{gl_HEADER_FOO_H}.  This convention is useful
because sometimes a header and a function name coincide (for example,
@code{fcntl} and @code{fcntl.h}).

For modules that provide a replacement, it is useful to split the Autoconf
macro into two macro definitions: one that detects whether the replacement
is needed and requests the replacement by setting a @code{HAVE_FOO}
variable to 0 or a @code{REPLACE_FOO} variable to 1 (this is the
entry point, say @code{gl_FUNC_FOO}), and one that arranges for the macros
needed by the replacement code @code{lib/foo.c} (typically called
@code{gl_PREREQ_FOO}).  The reason of this separation is
@enumerate
@item
to make it easy to update the Autoconf macros when you have modified the
source code file: after changing @code{lib/foo.c}, all you have to review
is the @code{Depends-on} section of the module description and the
@code{gl_PREREQ_FOO} macro in the Autoconf macro file.
@item
The Autoconf macros are often large enough that splitting them eases
maintenance.
@end enumerate

Autoconf macro files in Gnulib all start with a header consisting of
@c https://lists.gnu.org/archive/html/bug-gnulib/2024-04/msg00053.html
@enumerate
@item
A comment line with the file name.
This is useful because in some cases the generated @code{aclocal.m4}
file does not contain a reference to the @code{.m4} file but its entire
contents.
The comment makes it clear which @code{.m4} file is where in the
@code{aclocal.m4} file.
@item
A comment line with a serial number.
This is useful when people use the @samp{aclocal --install} command.
@code{aclocal} will then refrain from copying a file with a smaller
serial number onto a file with a larger serial number.
The serial number should be a positive integer on the main branch,
or a positive fractional number on a stable branch.
@item
The copyright and license header, as usual.
@end enumerate


@node Using @code{AC_LIBOBJ}
@section Making proper use of @code{AC_LIBOBJ}

Source files that provide a replacement should be only compiled on the
platforms that need this replacement.  While it is actually possible
to compile a @code{.c} file whose contents is entirely @code{#ifdef}'ed
out on the platforms that don't need the replacement, this practice is
discouraged because
@itemize @bullet
@item
It makes the build time longer than needed, by invoking the compiler for
nothing.
@item
It produces a @code{.o} file that suggests that a replacement was needed.
@item
Empty object files produce a linker warning on some platforms: MSVC.
@end itemize

The typical idiom for invoking @code{AC_LIBOBJ} is thus the following,
in the module description:

@smallexample
if test $HAVE_FOO = 0 || test $REPLACE_FOO = 1; then
  AC_LIBOBJ([foo])
  gl_PREREQ_FOO
fi
@end smallexample

Important: Do not place @code{AC_LIBOBJ} invocations in the Autoconf
macros in the @code{m4/} directory.  The purpose of the Autoconf macros
is to determine what features or bugs the platform has, and to make
decisions about which replacements are needed.  The purpose of the
@code{configure.ac} and @code{Makefile.am} sections of the module
descriptions is to arrange for the replacements to be compiled.
@strong{Source file names do not belong in the @code{m4/} directory.}

When an @code{AC_LIBOBJ} invocation is unconditional, it is simpler
to just have the source file compiled through an Automake variable
augmentation: In the @code{Makefile.am} section write

@smallexample
lib_SOURCES += foo.c
@end smallexample

When a module description contains an @code{AC_LIBOBJ([foo])}
invocation, you @strong{must} list the source file @code{lib/foo.c}
in the @code{Files} section.  This is needed even if the module
depends on another module that already lists @code{lib/foo.c} in its
@code{Files} section -- because your module might be used among
the test modules (in the directory specified through @samp{--tests-base})
and the other module among the main modules (in the directory specified
through @samp{--source-base}), and in this situation, the
@code{AC_LIBOBJ([foo])} of your module can only be satisfied by having
@code{foo.c} be present in the tests source directory as well.

@node Unit test modules
@section Unit test modules

A unit test that is a simple C program usually has a module description as
simple as this:

@smallexample
Files:
tests/test-foo.c
tests/macros.h

Depends-on:

configure.ac:

Makefile.am:
TESTS += test-foo
check_PROGRAMS += test-foo
@end smallexample

The test program @file{tests/test-foo.c} often has the following structure:

@itemize
@item
First comes the obligatory @samp{#include <config.h>}.

@item
Second comes the include of the header file that declares the API being tested.
Including it here verifies that said header file is self-contained.

@item
Then come other includes.  In particular, the file @file{macros.h} is often
used here.  It contains a convenient @code{ASSERT} macro.
@end itemize

The body of the test, then, contains many @code{ASSERT} invocations.  When
a test fails, the @code{ASSERT} macro prints the line number of the failing
statement, thus giving you, the developer, an idea of which part of the test
failed, even when you don't have access to the machine where the test failed
and the reporting user cannot run a debugger.

Sometimes it is convenient to write part of the test as a shell script.
(For example, in areas related to process control or interprocess
communication, or when different locales should be tried.) In these cases,
the typical module description is like this:

@smallexample
Files:
tests/test-foo.sh
tests/test-foo.c
tests/macros.h

Depends-on:

configure.ac:

Makefile.am:
TESTS += test-foo.sh
TESTS_ENVIRONMENT += FOO_BAR='@@FOO_BAR@@'
check_PROGRAMS += test-foo
@end smallexample

Here, the @code{TESTS_ENVIRONMENT} variable can be used to pass values
determined by @code{configure} or by the @code{Makefile} to the shell
script, as environment variables.  The Autoconf values @code{EXEEXT}
and @code{srcdir} are already provided as environment variables,
through an initial value of @code{TESTS_ENVIRONMENT} that
@code{gnulib-tool} puts in place.

Regardless of the specific form of the unit test, the following guidelines
should be respected:

@itemize
@item
A test indicates success by exiting with exit code 0.  It should normally
not produce output in this case.  (Output to temporary files that are
cleaned up at the end of the test are possible, of course.)
@item
A test indicates failure by exiting with an exit code different from 0 and 77,
typically 1.  It is useful to print a message about the failure in this case.
The @code{ASSERT} macro already does so.
@item
A test indicates "skip", that is, that most of its interesting functionality
could not be performed, through a return code of 77.  A test should also
print a message to stdout or stderr about the reason for skipping.
For example:
@smallexample
  fputs ("Skipping test: multithreading not enabled\n", stderr);
  return 77;
@end smallexample
Such a message helps detecting bugs in the autoconf macros: A simple message
@samp{SKIP: test-foo} does not sufficiently catch the attention of the user.

@node Incompatible changes
@section Incompatible changes

Incompatible changes to Gnulib modules should be mentioned in Gnulib's
@file{NEWS} file.  Incompatible changes here mean that existing source code
may not compile or work any more.

We don't mean changes in the binary interface (ABI), since
@enumerate
@item
Gnulib code is used in source-code form.
@item
The user who distributes libraries that contain Gnulib code is supposed to
bump the version number in the way described in the Libtool documentation
before every release.
@end enumerate


@node Extending Gnulib
@chapter Extending Gnulib

Gnulib modules are intended to be suitable for widespread use.  Most
problems with Gnulib can and should be fixed in a generic way, so that
all of Gnulib's users can benefit from the change.  But occasionally a
problem arises that is difficult or undesirable to fix generically, or
a project that uses Gnulib may need to work around an issue before the
Gnulib maintainers commit a final fix.  Maintainers may also want to
add their own pools of modules to projects as Gnulib ``staging
areas.''

The obvious way to make local changes to Gnulib modules is to use
@command{gnulib-tool} to check out pristine modules, then to modify
the results in-place.  This works well enough for short-lived
experiments.  It is harder to keep modified versions of Gnulib modules
for a long time, even though Git (or another distributed version
control systems) can help out a lot with this during the development
process.

Git, however, doesn't address the distribution issue.  When a package
``foobar'' needs a modified version of, say, @file{stdint.in.h}, it
either has to put a comment into @file{foobar/autogen.sh} saying
``Attention! This doesn't work with a pristine Gnulib, you need this
and that patch after checking out Gnulib,'' or it has to use the
@samp{--avoid=stdint-h} option and provide the modified @code{stdint-h}
module in a different directory.

The @option{--local-dir} option to @command{gnulib-tool} solves this
problem.  It allows the package to override or augment Gnulib.  This
means:

@itemize @bullet
@item
You can store files that are to override Gnulib files or modules.

@item
You can store context diffs to be applied to Gnulib files.

@item
You can add modules of your own, that are not (yet) in Gnulib.

@item
You can also add unstructured amounts of code to the library, by
grouping the non-Gnulib files of the library in a single kitchen-sink
``module.''  (This kind of kitchen-sink module is not needed when you
use the @command{gnulib-tool} option @option{--makefile-name}.)
@end itemize

In a release tarball, you can distribute the contents of this
@option{--local-dir} directory that will be combinable with newer
versions of Gnulib, barring incompatible changes to Gnulib.

If the @option{--local-dir=@var{directory}} option is specified, then
@command{gnulib-tool} looks in @file{@var{directory}} whenever it
reads a file from the Gnulib directory.  Suppose @command{gnulib-tool}
is looking for @var{file}.  Then:

@itemize @bullet
@item
If @file{@var{directory}/@var{file}} exists, then @command{gnulib-tool} uses
it instead of the file included in Gnulib.

@item
Otherwise, if @file{@var{directory}/@var{file}.diff} exists, then
@command{gnulib-tool} uses the file from Gnulib after applying the diff
using the @command{patch} program.

@item
Otherwise, @command{gnulib-tool} uses the file included in Gnulib.
@end itemize

You can specify the @option{--local-dir} multiple times.  In this case,
the first specified directory has the highest precedence.  That is, a
@file{@var{file}} found in one directory will shadow any @file{@var{file}}
and @file{@var{file}.diff} in the later directories and in the Gnulib
directory.  And a file @file{@var{file}.diff} found in one directory will
be applied on top of the combination of @file{@var{file}} and
@file{@var{file}.diff} files found in the later directories and in the
Gnulib directory.

Please make wise use of this option.  It also allows you to easily
hold back modifications you make to Gnulib macros in cases it may be
better to share them.

@node POSIX Substitutes Library
@chapter Building the ISO C and POSIX Substitutes

This section shows a radically different way to use Gnulib.

You can extract the ISO C / POSIX substitutes part of gnulib by running
the command
@smallexample
gnulib-tool --create-testdir --source-base=lib \
            --dir=/tmp/posixlib `posix-modules`
@end smallexample

@noindent
The command @samp{posix-modules} is found in the same directory as
@code{gnulib-tool}.

The resulting directory can be built on a particular platform,
independently of the program being ported.  Then you can configure and
build any program, by setting @code{CPPFLAGS} and @code{LDFLAGS} at
configure time accordingly: set @code{CPPFLAGS="-I.../posixlib/lib"}, plus
any essential type definitions and flags that you find in
@code{.../posixlib/config.h}, and set
@code{LDFLAGS=".../posixlib/lib/libgnu.a"}.

This way of using Gnulib is useful when you don't want to modify the program's
source code, or when the program uses a mix between C and C++ sources
(requiring separate builds of the @code{posixlib} for the C compiler and
for the C++ compiler).

@node Keyword Substitutes

This chapter describes which keywords specified by ISO C are
substituted by Gnulib.

@end menu

@node alignof
@section @code{alignof} and @code{alignas}

Gnulib module: alignasof
@mindex alignasof

The @code{alignasof} module arranges for @code{alignas} and @code{alignof}
to be more like standard C@.

Portability problems fixed by Gnulib:
@itemize
@item
On pre-C23 platforms, @code{<stdalign.h>} must be included before
using @code{alignas} or @code{alignof}.
@xref{stdalign.h}.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
The set of alignments supported by @code{alignas} is implementation
dependent, and implementations need not support alignments greater
than @code{alignof (max_align_t)}.

@item
Some older platforms do not support @code{alignas}.
To test this, use the @code{alignasof} module
along with the @code{#if} conditional
@code{(defined alignas || defined __alignas_is_defined
|| 202311 <= __STDC_VERSION__ || 201103 <= __cplusplus)}.
Platforms where @code{alignas} does not work include:
IBM XL C for AIX V16.1.

@item
On some platforms, the argument of @code{alignas} must be an integer
constant like @samp{8}, instead of an integer constant expression
like @samp{4 + 4} that evaluates to 8:
GCC 4.9.

@item
On pre-C23 platforms, @code{alignas} and @code{alignof} are macros.
@end itemize

@node bool
@section @code{bool}

Gnulib module: bool
@mindex bool

Portability problems fixed by Gnulib:
@itemize
@item
The keywords @code{bool}, @code{true}, and @code{false} are not available:
gcc 12 and other compilers predating C23.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On pre-C23 platforms, the keyword substitutes are macros.

@item
On pre-C23 platforms, the keyword substitutes assume C99 or later.
@end itemize

@node nullptr
@section @code{nullptr}

Gnulib module: nullptr
@mindex nullptr

@cindex null pointer
The @code{nullptr} module arranges for @code{nullptr} to act
like standard C and C++.

The @code{nullptr} keyword yields a null pointer.  It differs from
the @code{NULL} macro, in that @code{NULL} might be an integer whereas
@code{nullptr} is of a special @code{nullptr_t} type with only one
value, namely @code{nullptr} itself.  Using @code{nullptr} can help
some compilers emit more sensible warnings, can avoid the need to cast
a null pointer passed to a function prototyped with an ellipsis, and
removes the need to include @code{<stddef.h>} merely to define
@code{NULL}.

Portability problems fixed by Gnulib:
@itemize
@item
Some platforms lack @code{nullptr}:
For C: GCC 12, Clang 15, and other pre-2023 C compilers.
For C++: pre-2011 C++ compilers.

@item
Some platforms incorrectly warn when @code{nullptr} is a sentinel argument:
GCC 13.2 and 14.0.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On older platforms, @code{nullptr} is a macro instead of a keyword.

@item
On older platforms, @code{nullptr} does not have the type @code{nullptr_t}.
In C, it has type @code{void *}; in C++ it has an integer type.

@item
On older platforms Gnulib cannot easily emulate @code{nullptr_t}, so
null pointer type checking is more error prone.  In C, @code{_Generic}
expressions cannot reliably distinguish the type of @code{nullptr}
from integer or @code{void *} types.  C++ overloading has similar
limitations.

@item
GCC 14 defines @code{nullptr_t} even when @code{<stddef.h>} is not
included.  This bug is fixed in GCC 15.
@end itemize

@node static_assert
@section @code{static_assert}

Gnulib module: assert-h
@mindex assert-h

The @code{assert-h} module arranges for both @code{static_assert} and
@code{<assert.h>} to be like standard C@.  @xref{assert.h}.

Portability problems fixed by Gnulib:
@itemize
@item
Pre-C11 platforms lack @code{static_assert}.

@item
On pre-C23 platforms, @code{<assert.h>} must be included before
using @code{static_assert}.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On pre-C23 platforms, @code{static_assert} is a macro.
@end itemize

@node Header File Substitutes

@node Native Windows Support
@chapter Native Windows Support

There are three ways to create binaries that run on Microsoft Windows:
@itemize
@item
Native binaries, built using the MinGW tool chain.
@item
Native binaries, built using the MSVC (MS Visual C/C++) tool chain.
@item
Binaries for the Cygwin environment.
@end itemize

This chapter deals with the MinGW and MSVC platforms, commonly called
``native Windows'' platforms.  Cygwin, on the other hand, is close enough
to POSIX that it can be treated like any other Unix-like platform.

@node Build Infrastructure Files
@chapter Build Infrastructure Files

Gnulib contains also a small number of files that are not part of
modules.  They are meant to be imported into packages by means of
@samp{gnulib-tool --copy-file}, not @samp{gnulib-tool --import}.  For
example, the commands to import the files @code{config.guess} and
@code{config.sub} are
@smallexample
for file in config.guess config.sub; do
  $GNULIB_TOOL --copy-file build-aux/$file \
    && chmod a+x build-aux/$file \
    || exit $?
done
@end smallexample

Packages that don't use Gnulib can get hold of these files through
direct download from Gnulib's git repository.  The commands to do this
look as follows:
@smallexample
for file in config.guess config.sub; do
  echo "$0: getting $file..."
  wget -q --timeout=5 -O build-aux/$file.tmp "https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob_plain;f=build-aux/$@{file@};hb=HEAD" \
    && mv build-aux/$file.tmp build-aux/$file \
    && chmod a+x build-aux/$file
  retval=$?
  rm -f build-aux/$file.tmp
  test $retval -eq 0 || exit $retval
done

@node Recognizing platforms
@section Recognizing platforms

@table @code
@item build-aux/config.guess
@itemx build-aux/config.sub
These files are helper scripts, invoked by the @samp{configure} script.
@code{config.guess} recognizes the platform on which the script is
running, and produces a triplet of the form
@code{@var{cpu-type}-@var{vendor}-@var{operating_system}}.
@code{config.sub} receives a possibly abbreviated triplet and produces a
canonical triplet for a platform.  For more information, see
@ifinfo
@ref{Configuration,,,standards}.
@end ifinfo
@ifnotinfo
@url{https://www.gnu.org/prep/standards/html_node/Configuration.html}.
@end ifnotinfo
@end table

It is important that you always include the newest versions of these two
files in your tarball, because people who work on emerging platforms
otherwise have a hard time building your package.

@node Utilities for Makefiles
@section Utilities for Makefiles

These programs can be used in Makefiles.  Some
of them are also described in
@ifinfo
@ref{Auxiliary Programs,,,automake}.
@end ifinfo
@ifnotinfo
@url{https://www.gnu.org/software/automake/manual/html_node/Auxiliary-Programs.html}.
@end ifnotinfo

@table @code
@item build-aux/ar-lib
@itemx build-aux/compile
These two scripts are necessary for supporting portability to native
Windows with the MSVC compiler.  @code{compile} is a wrapper script that
invokes the compiler and provides a command-line interface compatible
with Unix compilers.  Similarly, @code{ar-lib} is a wrapper script that
provides a command-line interface compatible with Unix @code{ar}.
@item build-aux/depcomp
This is a helper script, used by Makefile rules generated by GNU
Automake.  It generates Makefile dependencies while compiling a file.
@item build-aux/install-sh
This is a helper script, used by Makefile rules generated by GNU
Automake.  It installs files during the @code{make install} phase.  In
the Makefile, don't use this file directly; always use
@code{$(INSTALL_PROGRAM)} or @code{$(INSTALL_DATA)} instead.
@item build-aux/mdate-sh
This script determines the modification time of a file and pretty-prints
it.  The typical use is to add a ``Last modified'' line to the
documentation.
@item build-aux/mkinstalldirs
This is a helper script, used by Makefile rules generated by GNU
Automake.  It creates directories during the @code{make install} phase.
It is roughly equivalent to @samp{mkdir -p} (except that the latter is
not portable).  In the Makefile, don't use this file directly; always
use @code{$(MKDIR_P)} instead.
@item build-aux/mktempd
This script creates a temporary directory.  It is roughly equivalent to
@samp{mktemp -d} (except that the latter is not portable).
@item build-aux/move-if-change
This script moves a freshly generated file to a destination file, with a
special optimization for the case that both files are identical.  In
this case the freshly generated file is deleted, and the time stamp of
the destination file is @emph{not} changed.  This is useful when
updating a file that rarely actually changes and which many Makefile
targets depend upon.
@end table

@node Developer tools
@section Programs for developing in Git checkouts

These programs can help when developing in a Git
checkout.  The maintainer of the package copies these programs into the
version control of the package, so that co-developers can use these
tools right away.

@table @code
@item top/gitsub.sh
This program manages the subdirectories of a Git checkout that come from
other packages, including Gnulib.

@item top/bootstrap
@itemx top/autopull.sh
@itemx top/autogen.sh
@itemx top/bootstrap-funclib.sh
This is a set of three programs and a function library, that manage
the source directory of a package, preparing for the state where
@samp{./configure} can be used.

@code{autopull.sh} is a program for fetching dependencies that may
require network accesses.  It manages the Git submodules, including
Gnulib -- assuming that Gnulib is a Git submodule. It also can fetch
the PO files for internationalized packages.

@code{autogen.sh} is a program that is meant to be run after
@code{autopull.sh}.  It generates all autogeneratable files that are
omitted from version control.  Usually this means that it invokes
@code{gnulib-tool} and @code{automake}, that generate files from other
files.

@code{bootstrap} is a wrapper around both:
@code{./bootstrap --pull} is equivalent to @code{./autopull.sh},
@code{./bootstrap --gen} is equivalent to @code{./autogen.sh}.
Plain @code{./bootstrap} is equivalent to @code{./autopull.sh}
immediately followed by @code{./autogen.sh}; however, because plain
@code{./bootstrap} mixes version control management and
generation of files in non-obvious ways, it has a number of usability
issues for the advanced developer.

@code{bootstrap-funclib.sh} is a function library for these three
programs.  It is not meant to be used directly.

All three programs make use of a configuration file, called
@code{bootstrap.conf}.

@item build-aux/bootstrap
This acts like @code{top/bootstrap}, except it does not
need the companion files @code{autogen.sh},
@code{autopull.sh}, and @code{bootstrap-funclib.sh}
so it avoids some clutter in your project's top level directory.
With this approach, you update via @code{./bootstrap --pull} and
@code{./bootstrap --gen} instead of via @code{./autopull.sh} and
@code{./autogen.sh}.  Otherwise this approach acts similarly, and
uses the same @code{bootstrap.conf} file.

@item build-aux/bootstrap.conf
This is the template configuration file.  After copying it into the
top-level directory of your package, you need to customize it.

@item build-aux/po/Makefile.in.in
@itemx build-aux/po/remove-potcdate.sed
These are auxiliary files used by @code{bootstrap}.  You don't have to
copy them yourself; @code{bootstrap} will do that.

@node For building documentation
@section Utilities for building documentation

These are auxiliary files for building documentation.

@table @code
@item build-aux/texinfo.tex
This file is needed for the conversion of Texinfo-format documentation
to PDF, PostScript, or DVI formats.  It implements the GNU Texinfo
commands on top of plain TeX.
@item build-aux/x-to-1.in
This file, once processed, gives a program @code{x-to-1}, that produces
a manual page for a program, by combining a skeleton with the program's
@code{--help} output.
