8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

47# This function generate linker scripts in /usr/lib for dynamic 55else

49# the .so in /lib, and the .a in /usr/lib. What happens is that
50# in some cases when linking dynamic, the .a in /usr/lib is used

58#
59# Note that you should in general use the unversioned name of

149# @FUNCTION: eshopts_push
150# @USAGE: [options to `set` or `shopt`]
151# @DESCRIPTION:
152# Often times code will want to enable a shell option to change code behavior.
153# Since changing shell options can easily break other pieces of code (which
154# assume the default state), eshopts_push is used to (1) push the current shell
155# options onto a stack and (2) pass the specified arguments to set.
156#
157# If the first argument is '-s' or '-u', we assume you want to call `shopt`
158# rather than `set` as there are some options only available via that.
159#
160# A common example is to disable shell globbing so that special meaning/care
161# may be used with variables/arguments to custom functions. That would be:
162# @CODE
163# eshopts_push -s noglob
164# for x in ${foo} ; do
165# if ...some check... ; then
166# eshopts_pop

131# This function is for bulk patching, or in theory for just one 270# @FUNCTION: epatch
132# or two patches. 271# @USAGE: [options] [patches] [dirs of patches]
272# @DESCRIPTION:
273# epatch is designed to greatly simplify the application of patches. It can
274# process patch files directly, or directories of patches. The patches may be
275# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
276# the -p option as epatch will automatically attempt -p0 to -p5 until things
277# apply successfully.
133# 278#
134# It should work with .bz2, .gz, .zip and plain text patches. 279# If you do not specify any patches/dirs, then epatch will default to the
135# Currently all patches should be the same format. 280# directory specified by EPATCH_SOURCE.
136# 281#
137# You do not have to specify '-p' option to patch, as it will 282# Any options specified that start with a dash will be passed down to patch
138# try with -p0 to -p5 until it succeed, or fail at -p5. 283# for this specific invocation. As soon as an arg w/out a dash is found, then
284# arg processing stops.
139# 285#
140# Above EPATCH_* variables can be used to control various defaults, 286# When processing directories, epatch will apply all patches that match:
141# bug they should be left as is to ensure an ebuild can rely on 287# @CODE
142# them for. 288# if ${EPATCH_FORCE} != "yes"
143#
144# Patches are applied in current directory.
145#
146# Bulk Patches should preferibly have the form of:
147#
148# ??_${ARCH}_foo.${EPATCH_SUFFIX} 289# ??_${ARCH}_foo.${EPATCH_SUFFIX}
290# else
291# *.${EPATCH_SUFFIX}
292# @CODE
293# The leading ?? are typically numbers used to force consistent patch ordering.
294# The arch field is used to apply patches only for the host architecture with
295# the special value of "all" means apply for everyone. Note that using values
296# other than "all" is highly discouraged -- you should apply patches all the
297# time and let architecture details be detected at configure/compile time.
149# 298#
150# For example: 299# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
300# for patches to apply.
151# 301#
152# 01_all_misc-fix.patch.bz2 302# Refer to the other EPATCH_xxx variables for more customization of behavior.
153# 02_sparc_another-fix.patch.bz2
154#
155# This ensures that there are a set order, and you can have ARCH
156# specific patches.
157#
158# If you however give an argument to epatch(), it will treat it as a
159# single patch that need to be applied if its a file. If on the other
160# hand its a directory, it will set EPATCH_SOURCE to this.

577# of these three directories to exist will be the one to use, ignoring
578# any more general directories which might exist as well. They must end
579# in ".patch" to be applied.
580#
581# User patches are intended for quick testing of patches without ebuild
582# modifications, as well as for permanent customizations a user might
583# desire. Obviously, there can be no official support for arbitrarily
584# patched ebuilds. So whenever a build log in a bug report mentions that
585# user patches were applied, the user should be asked to reproduce the
586# problem without these.
587#
588# Not all ebuilds do call this function, so placing patches in the
589# stated directory might or might not work, depending on the package and
590# the eclasses it inherits and uses. It is safe to call the function
591# repeatedly, so it is always possible to add a call at the ebuild
592# level. The first call is the time when the patches will be
593# applied.
594#
595# Ideally, this function should be called after gentoo-specific patches
596# have been applied, so that their code can be modified as well, but

1425# flags.
1426#
1427# If '--modules' argument is passed, .la files for modules (plugins) are
1428# removed as well. This is usually useful when the package installs
1429# plugins and the plugin loader does not use .la files.

1431# If '--all' argument is passed, all .la files are removed without
1432# performing any heuristic on them. You shouldn't ever use that,
1433# and instead report a bug in the algorithm instead.
1434#
1435# The .a files are only removed whenever corresponding .la files state
1436# that they should not be linked to, i.e. whenever these files
1437# correspond to plugins.
1438#
