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!

20# libs in /lib. This is to fix linking problems when you have
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.

31# Note that you should in general use the unversioned name of
32# the library, as ldconfig should usually update it correctly
33# to point to the latest version of the library present.

103# @FUNCTION: eshopts_push
104# @USAGE: [options to `set` or `shopt`]
105# @DESCRIPTION:
106# Often times code will want to enable a shell option to change code behavior.
107# Since changing shell options can easily break other pieces of code (which
108# assume the default state), eshopts_push is used to (1) push the current shell
109# options onto a stack and (2) pass the specified arguments to set.
110#
111# If the first argument is '-s' or '-u', we assume you want to call `shopt`
112# rather than `set` as there are some options only available via that.
113#
114# A common example is to disable shell globbing so that special meaning/care
115# may be used with variables/arguments to custom functions. That would be:
116# @CODE
117# eshopts_push -o noglob
118# for x in ${foo} ; do
119# if ...some check... ; then
120# eshopts_pop
85 return 0 121# return 0
122# fi
123# done
124# eshopts_pop
125# @CODE
126eshopts_push() {
127 # have to assume __ESHOPTS_SAVE__ isn't screwed with
128 # as a `declare -a` here will reset its value
129 local i=${#__ESHOPTS_SAVE__[@]}
130 if [[ $1 == -[su] ]] ; then
131 __ESHOPTS_SAVE__[$i]=$(shopt -p)

106# This function is for bulk patching, or in theory for just one 196# @FUNCTION: epatch
107# or two patches. 197# @USAGE: [patches] [dirs of patches]
198# @DESCRIPTION:
199# epatch is designed to greatly simplify the application of patches. It can
200# process patch files directly, or directories of patches. The patches may be
201# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
202# the -p option as epatch will automatically attempt -p0 to -p5 until things
203# apply successfully.
108# 204#
109# It should work with .bz2, .gz, .zip and plain text patches. 205# If you do not specify any options, then epatch will default to the directory
110# Currently all patches should be the same format. 206# specified by EPATCH_SOURCE.
111# 207#
112# You do not have to specify '-p' option to patch, as it will 208# When processing directories, epatch will apply all patches that match:
113# try with -p0 to -p5 until it succeed, or fail at -p5. 209# @CODE
114# 210# if ${EPATCH_FORCE} != "yes"
115# Above EPATCH_* variables can be used to control various defaults,
116# bug they should be left as is to ensure an ebuild can rely on
117# them for.
118#
119# Patches are applied in current directory.
120#
121# Bulk Patches should preferibly have the form of:
122#
123# ??_${ARCH}_foo.${EPATCH_SUFFIX} 211# ??_${ARCH}_foo.${EPATCH_SUFFIX}
212# else
213# *.${EPATCH_SUFFIX}
214# @CODE
215# The leading ?? are typically numbers used to force consistent patch ordering.
216# The arch field is used to apply patches only for the host architecture with
217# the special value of "all" means apply for everyone. Note that using values
218# other than "all" is highly discouraged -- you should apply patches all the
219# time and let architecture details be detected at configure/compile time.
124# 220#
125# For example: 221# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
222# for patches to apply.
126# 223#
127# 01_all_misc-fix.patch.bz2 224# Refer to the other EPATCH_xxx variables for more customization of behavior.
128# 02_sparc_another-fix.patch.bz2
129#
130# This ensures that there are a set order, and you can have ARCH
131# specific patches.
132#
133# If you however give an argument to epatch(), it will treat it as a
134# single patch that need to be applied if its a file. If on the other
135# hand its a directory, it will set EPATCH_SOURCE to this.

460# desire. Obviously, there can be no official support for arbitrarily

467# the eclasses it inherits and uses. It is safe to call the function
468# repeatedly, so it is always possible to add a call at the ebuild
469# level. The first call is the time when the patches will be
