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!

21# the .so in /lib, and the .a in /usr/lib. What happens is that
22# in some cases when linking dynamic, the .a in /usr/lib is used
23# instead of the .so in /lib due to gcc/libtool tweaking ld's
24# library search path. This cause many builds to fail.

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

100# This function is for bulk patching, or in theory for just one 258# @FUNCTION: epatch
101# or two patches. 259# @USAGE: [patches] [dirs of patches]
260# @DESCRIPTION:
261# epatch is designed to greatly simplify the application of patches. It can
262# process patch files directly, or directories of patches. The patches may be
263# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
264# the -p option as epatch will automatically attempt -p0 to -p5 until things
265# apply successfully.
102# 266#
103# It should work with .bz2, .gz, .zip and plain text patches. 267# If you do not specify any options, then epatch will default to the directory
104# Currently all patches should be the same format. 268# specified by EPATCH_SOURCE.
105# 269#
106# You do not have to specify '-p' option to patch, as it will 270# When processing directories, epatch will apply all patches that match:
107# try with -p0 to -p5 until it succeed, or fail at -p5. 271# @CODE
108# 272# if ${EPATCH_FORCE} != "yes"
109# Above EPATCH_* variables can be used to control various defaults,
110# bug they should be left as is to ensure an ebuild can rely on
111# them for.
112#
113# Patches are applied in current directory.
114#
115# Bulk Patches should preferibly have the form of:
116#
117# ??_${ARCH}_foo.${EPATCH_SUFFIX} 273# ??_${ARCH}_foo.${EPATCH_SUFFIX}
274# else
275# *.${EPATCH_SUFFIX}
276# @CODE
277# The leading ?? are typically numbers used to force consistent patch ordering.
278# The arch field is used to apply patches only for the host architecture with
279# the special value of "all" means apply for everyone. Note that using values
280# other than "all" is highly discouraged -- you should apply patches all the
281# time and let architecture details be detected at configure/compile time.
118# 282#
119# For example: 283# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
284# for patches to apply.
120# 285#
121# 01_all_misc-fix.patch.bz2 286# Refer to the other EPATCH_xxx variables for more customization of behavior.
122# 02_sparc_another-fix.patch.bz2
123#
124# This ensures that there are a set order, and you can have ARCH
125# specific patches.
126#
127# If you however give an argument to epatch(), it will treat it as a
128# single patch that need to be applied if its a file. If on the other
129# hand its a directory, it will set EPATCH_SOURCE to this.
