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!

101# in some cases when linking dynamic, the .a in /usr/lib is used 102# Often times code will want to enable a shell option to change code behavior.

103# library search path. This cause many builds to fail. 104# assume the default state), eshopts_push is used to (1) push the current shell
104# See bug #4411 for more info. 105# options onto a stack and (2) pass the specified arguments to set.
105# 106#
106# To use, simply call: 107# If the first argument is '-s' or '-u', we assume you want to call `shopt`

182# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
183# or two patches. 193# @USAGE: [patches] [dirs of patches]
194# @DESCRIPTION:
195# epatch is designed to greatly simplify the application of patches. It can
196# process patch files directly, or directories of patches. The patches may be
197# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
198# the -p option as epatch will automatically attempt -p0 to -p5 until things
199# apply successfully.
184# 200#
185# It should work with .bz2, .gz, .zip and plain text patches. 201# If you do not specify any options, then epatch will default to the directory
186# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
187# 203#
188# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
189# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
190# 206# if ${EPATCH_FORCE} != "yes"
191# Above EPATCH_* variables can be used to control various defaults,
192# bug they should be left as is to ensure an ebuild can rely on
193# them for.
194#
195# Patches are applied in current directory.
196#
197# Bulk Patches should preferibly have the form of:
198#
199# ??_${ARCH}_foo.${EPATCH_SUFFIX} 207# ??_${ARCH}_foo.${EPATCH_SUFFIX}
208# else
209# *.${EPATCH_SUFFIX}
210# @CODE
211# The leading ?? are typically numbers used to force consistent patch ordering.
212# The arch field is used to apply patches only for the host architecture with
213# the special value of "all" means apply for everyone. Note that using values
214# other than "all" is highly discouraged -- you should apply patches all the
215# time and let architecture details be detected at configure/compile time.
200# 216#
201# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
202# 219#
203# 01_all_misc-fix.patch.bz2 220# Refer to the other EPATCH_xxx variables for more customization of behavior.
204# 02_sparc_another-fix.patch.bz2
205#
206# This ensures that there are a set order, and you can have ARCH
207# specific patches.
208#
209# If you however give an argument to epatch(), it will treat it as a
210# single patch that need to be applied if its a file. If on the other
211# hand its a directory, it will set EPATCH_SOURCE to this.

455# modifications, as well as for permanent customizations a user might
456# desire. Obviously, there can be no official support for arbitrarily
457# patched ebuilds. So whenever a build log in a bug report mentions that

465# level. The first call is the time when the patches will be
466# applied.
