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!

23# ecpu_check array_of_cpu_flags
24#
25# array_of_cpu_flags - An array of cpu flags to check against USE flags
26#
27# Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28# cpu flag that is not supported in their processor flags, it will warn the
29# user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30# obviously using different cpu flags than their own cpu ). Examples:
31#
32# CPU_FLAGS=(mmx mmx2 sse sse2)

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

177# This function is for bulk patching, or in theory for just one 192# @FUNCTION: epatch
178# 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.
179# 200#
180# 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
181# Currently all patches should be the same format. 202# specified by EPATCH_SOURCE.
182# 203#
183# You do not have to specify '-p' option to patch, as it will 204# When processing directories, epatch will apply all patches that match:
184# try with -p0 to -p5 until it succeed, or fail at -p5. 205# @CODE
185# 206# if ${EPATCH_FORCE} != "yes"
186# Above EPATCH_* variables can be used to control various defaults,
187# bug they should be left as is to ensure an ebuild can rely on
188# them for.
189#
190# Patches are applied in current directory.
191#
192# Bulk Patches should preferibly have the form of:
193#
194# ??_${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.
195# 216#
196# For example: 217# If EPATCH_SUFFIX is empty, then no period before it is implied when searching
218# for patches to apply.
197# 219#
198# 01_all_misc-fix.patch.bz2 220# Refer to the other EPATCH_xxx variables for more customization of behavior.
199# 02_sparc_another-fix.patch.bz2
200#
201# This ensures that there are a set order, and you can have ARCH
202# specific patches.
203#
204# If you however give an argument to epatch(), it will treat it as a
205# single patch that need to be applied if its a file. If on the other
206# 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.

2003# @FUNCTION: path_exists
2004# @USAGE: [-a|-o] <paths>
2005# @DESCRIPTION:
2006# Check if the specified paths exist. Works for all types of paths
2007# (files/dirs/etc...). The -a and -o flags control the requirements
2008# of the paths. They correspond to "and" and "or" logic. So the -a
2009# flag means all the paths must exist while the -o flag means at least
2010# one of the paths must exist. The default behavior is "and". If no
2011# paths are specified, then the return value is "false".

2014 [[ ${opt} == -[ao] ]] && shift || opt="-a"
2015
2016 # no paths -> return false
2017 # same behavior as: [[ -e "" ]]
