6# @MAINTAINER:

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.
4# 14#
5# This eclass is for general purpose functions that most ebuilds 15# Due to the nature of this eclass, some functions may have maintainers
6# have to implement themselves. 16# different from the overall eclass!
7#
8# NB: If you add anything, please comment it!

89# @FUNCTION: eshopts_push
90# @USAGE: [options to `set` or `shopt`]
91# @DESCRIPTION:
92# Often times code will want to enable a shell option to change code behavior.
93# Since changing shell options can easily break other pieces of code (which
94# assume the default state), eshopts_push is used to (1) push the current shell
95# options onto a stack and (2) pass the specified arguments to set.
96#
97# If the first argument is '-s' or '-u', we assume you want to call `shopt`
98# rather than `set` as there are some options only available via that.
99#
100# A common example is to disable shell globbing so that special meaning/care
101# may be used with variables/arguments to custom functions. That would be:
102# @CODE
103# eshopts_push -o noglob
104# for x in ${foo} ; do
105# if ...some check... ; then
106# eshopts_pop
107# return 0
108# fi
109# done
110# eshopts_pop
111# @CODE
112eshopts_push() {
113 # have to assume __ESHOPTS_SAVE__ isn't screwed with
114 # as a `declare -a` here will reset its value
115 local i=${#__ESHOPTS_SAVE__[@]}
116 if [[ $1 == -[su] ]] ; then
117 __ESHOPTS_SAVE__[$i]=$(shopt -p)
118 [[ $# -eq 0 ]] && return 0
119 shopt "$@" || die "eshopts_push: bad options to shopt: $*"
120 else
121 __ESHOPTS_SAVE__[$i]=$-
122 [[ $# -eq 0 ]] && return 0
123 set "$@" || die "eshopts_push: bad options to set: $*"
124 fi
125}
126
127# @FUNCTION: eshopts_pop
128# @USAGE:
129# @DESCRIPTION:
130# Restore the shell options to the state saved with the corresponding
131# eshopts_push call. See that function for more details.
132eshopts_pop() {
133 [[ $# -ne 0 ]] && die "eshopts_pop takes no arguments"
134 local i=$(( ${#__ESHOPTS_SAVE__[@]} - 1 ))

63# This function is for bulk patching, or in theory for just one 182# @FUNCTION: epatch
64# or two patches. 183# @USAGE: [patches] [dirs of patches]
184# @DESCRIPTION:
185# epatch is designed to greatly simplify the application of patches. It can
186# process patch files directly, or directories of patches. The patches may be
187# compressed (bzip/gzip/etc...) or plain text. You generally need not specify
188# the -p option as epatch will automatically attempt -p0 to -p5 until things
189# apply successfully.
65# 190#
66# It should work with .bz2, .gz, .zip and plain text patches. 191# If you do not specify any options, then epatch will default to the directory
67# Currently all patches should be the same format. 192# specified by EPATCH_SOURCE.
68# 193#
69# You do not have to specify '-p' option to patch, as it will 194# When processing directories, epatch will apply all patches that match:
70# try with -p0 to -p5 until it succeed, or fail at -p5. 195# @CODE
71# 196# ${EPATCH_FORCE} == "yes"
72# Above EPATCH_* variables can be used to control various defaults,
73# bug they should be left as is to ensure an ebuild can rely on
74# them for.
75#
76# Patches are applied in current directory.
77#
78# Bulk Patches should preferibly have the form of:
79#
80# ??_${ARCH}_foo.${EPATCH_SUFFIX} 197# ??_${ARCH}_foo.${EPATCH_SUFFIX}
198# else
199# *.${EPATCH_SUFFIX}
200# @CODE
201# The leading ?? are typically numbers used to force consistent patch ordering.
202# The arch field is used to apply patches only for the host architecture with
203# the special value of "all" means apply for everyone. Note that using values
204# other than "all" is highly discouraged -- you should apply patches all the
205# time and let architecture details be detected at configure/compile time.
81# 206#
82# For example: 207# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
208# for patches to apply.
83# 209#
84# 01_all_misc-fix.patch.bz2 210# Refer to the other EPATCH_xxx variables for more customization of behavior.
85# 02_sparc_another-fix.patch.bz2
86#
87# This ensures that there are a set order, and you can have ARCH
88# specific patches.
89#
90# If you however give an argument to epatch(), it will treat it as a
91# single patch that need to be applied if its a file. If on the other
92# hand its a directory, it will set EPATCH_SOURCE to this.
