6# @MAINTAINER:
7# base-system@gentoo.org
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!

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

141# eshopts_push call. See that function for more details.

63# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
64# 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.
65# 200#
66# 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
67# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
68# 203#
69# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
70# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
71# 206# if ${EPATCH_FORCE} != "yes"
72# Above EPATCH_* variables can be used to control various defaults,
73# bug they should be left as is to ensure an ebuild can rely on
74# them for.
75#
76# Patches are applied in current directory.
77#
78# Bulk Patches should preferibly have the form of:
79#
80# ??_${ARCH}_foo.${EPATCH_SUFFIX} 207# ??_${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.
81# 216#
82# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
83# 219#
84# 01_all_misc-fix.patch.bz2 220# 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.

449# Applies user-provided patches to the source tree. The patches are
450# taken from /etc/portage/patches/<CATEGORY>/<PF|P|PN>/, where the first
451# of these three directories to exist will be the one to use, ignoring
452# any more general directories which might exist as well.
453#
454# User patches are intended for quick testing of patches without ebuild
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
458# user patches were applied, the user should be asked to reproduce the
459# problem without these.
460#
461# Not all ebuilds do call this function, so placing patches in the
462# stated directory might or might not work, depending on the package and
463# the eclasses it inherits and uses. It is safe to call the function
464# repeatedly, so it is always possible to add a call at the ebuild
465# level. The first call is the time when the patches will be
466# applied.
467#
468# Ideally, this function should be called after gentoo-specific patches
469# have been applied, so that their code can be modified as well, but
470# before calls to e.g. eautoreconf, as the user patches might affect
471# autotool input files as well.

1606# ex: built_with_use xchat gtk2 1861# @DESCRIPTION:
1607# 1862#
1608# Flags: -a all USE flags should be utilized 1863# Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
1609# -o at least one USE flag should be utilized 1864#
1610# --missing peform the specified action if the flag is not in IUSE (true/false/die) 1865# A temporary hack until portage properly supports DEPENDing on USE
1611# --hidden USE flag we're checking is hidden expanded so it isnt in IUSE 1866# flags being enabled in packages. This will check to see if the specified
1612# Note: the default flag is '-a' 1867# DEPEND atom was built with the specified list of USE flags. The
1868# --missing option controls the behavior if called on a package that does
1869# not actually support the defined USE flags (aka listed in IUSE).
1870# The default is to abort (call die). The -a and -o flags control
1871# the requirements of the USE flags. They correspond to "and" and "or"
1872# logic. So the -a flag means all listed USE flags must be enabled
1873# while the -o flag means at least one of the listed IUSE flags must be
1874# enabled. The --hidden option is really for internal use only as it
1875# means the USE flag we're checking is hidden expanded, so it won't be found
1876# in IUSE like normal USE flags.
1877#
1878# Remember that this function isn't terribly intelligent so order of optional
1879# flags matter.
