# @BLURB: Eclass used to create and maintain a single group entry
# @DESCRIPTION:
# This eclass represents and creates a single group entry. The name
# of the group is derived from ${PN}, while (preferred) GID needs to
# be specified via ACCT_GROUP_ID. Packages (and users) needing the group
# in question should depend on the package providing it.
#
# Example:
# If your package needs group 'foo', you create 'acct-group/foo' package
# and add an ebuild with the following contents:
#
# @CODE
# EAPI=7
# inherit acct-group
# ACCT_GROUP_ID=200
# @CODE
#
# Then you add appropriate dependency to your package. The dependency
# type(s) should be:
# - DEPEND (+ RDEPEND) if the group is already needed at build time,
# - RDEPEND if it is needed at install time (e.g. you 'fowners' files
# in pkg_preinst) or run time.

# be specified via ACCT_USER_ID. Additional variables are provided
# to override the default home directory, shell and add group
# membership. Packages needing the user in question should depend
# on the package providing it.
#
# The ebuild needs to call acct-user_add_deps after specifying
# ACCT_USER_GROUPS.
#
# Example:
# If your package needs user 'foo' belonging to same-named group, you
# create 'acct-user/foo' package and add an ebuild with the following
# contents:
#
# @CODE
# EAPI=7
# inherit acct-user
# ACCT_USER_ID=200
# ACCT_USER_GROUPS=( foo )
# acct-user_add_deps

#
# Then you add appropriate dependency to your package. The dependency

# @ECLASS: alternatives.eclass
# @AUTHOR:
# Original author: Alastair Tse <liquidx@gentoo.org> (03 Oct 2003)
# @BLURB: Creates symlink to the latest version of multiple slotted packages.
# @DESCRIPTION:
# When a package is SLOT'ed, very often we need to have a symlink to the
# latest version. However, depending on the order the user has merged them,
# more often than not, the symlink maybe clobbered by the older versions.
#
# This eclass provides a convenience function that needs to be given a
# list of alternatives (descending order of recent-ness) and the symlink.
# It will choose the latest version it can find installed and create
# the desired symlink.
#
# There are two ways to use this eclass. First is by declaring two variables
# $SOURCE and $ALTERNATIVES where $SOURCE is the symlink to be created and
# $ALTERNATIVES is a list of alternatives. Second way is the use the function
# alternatives_makesym() like the example below.
# @EXAMPLE:
# pkg_postinst() {
# alternatives_makesym "/usr/bin/python" "/usr/bin/python2.3" "/usr/bin/python2.2"
# }
#
# The above example will create a symlink at /usr/bin/python to either
# /usr/bin/python2.3 or /usr/bin/python2.2. It will choose python2.3 over
# python2.2 if both exist.
#
# Alternatively, you can use this function:
#
# pkg_postinst() {
# alternatives_auto_makesym "/usr/bin/python" "/usr/bin/python[0-9].[0-9]"
# }
#
# This will use bash pathname expansion to fill a list of alternatives it can
# link to. It is probably more robust against version upgrades. You should
# consider using this unless you are want to do something special.

# @ECLASS: apache-module.eclass
# @MAINTAINER:
# apache-devs@gentoo.org
# @BLURB: Provides a common set of functions for apache modules
# @DESCRIPTION:
# This eclass handles apache modules in a sane way.
#
# To make use of this eclass simply call one of the need/want_apache functions
# described in depend.apache.eclass. Make sure you use the need/want_apache call
# after you have defined DEPEND and RDEPEND. Also note that you can not rely on
# the automatic RDEPEND=DEPEND that portage does if you use this eclass.
#
# See Bug 107127 for more information.
#
# @EXAMPLE:
#
# Here is a simple example of an ebuild for mod_foo:
#
# @CODE
# APACHE2_MOD_CONF="42_mod_foo"
# APACHE2_MOD_DEFINE="FOO"
# need_apache2
# @CODE
#
# A more complicated example for a module with non-standard locations:
#
# @CODE
# APXS2_S="${S}/apache22/src"
# APACHE2_MOD_FILE="${APXS2_S}/${PN}.so"
# APACHE2_MOD_CONF="42_${PN}"
# APACHE2_MOD_DEFINE="FOO"
# DOCFILES="docs/*.html"
# need_apache2_2
# @CODE
#
# A basic module configuration which just loads the module into apache:
#
# @CODE
# <IfDefine FOO>
# LoadModule foo_module modules/mod_foo.so
# </IfDefine>
# @CODE

# If your tool is not supported, please open a bug and we'll add support for it.

# @DESCRIPTION:
# Attempt to locate a CD based upon a file that is on the CD.
#
# If the data spans multiple discs then additional arguments can be
# given to check for more files. Call cdrom_load_next_cd() to scan for
# the next disc in the set.
#
# Sometimes it is necessary to support alternative CD "sets" where the
# contents differ. Alternative files for each disc can be appended to
# each argument, separated by the : character. This feature is
# frequently used to support installing from an existing installation.
# Note that after the first disc is detected, the set is locked so
# cdrom_load_next_cd() will only scan for files in that specific set on
# subsequent discs.
#
# The given files can be within named subdirectories. It is not
# necessary to specify different casings of the same filename as
# matching is done case-insensitively. Filenames can include special
# characters such as spaces. Only : is not allowed.
#
# If you don't want each disc to be referred to as "CD #1", "CD #2",
# etc. then you can optionally provide your own names. Set CDROM_NAME
# for a single disc, CDROM_NAMES as an array for multiple discs, or
# individual CDROM_NAME_# variables for each disc starting from 1.
#
# Despite what you may have seen in older ebuilds, it has never been
# possible to provide per-set disc names. This would not make sense as
# all the names are initially displayed before the first disc has been
# detected. As a workaround, you can redefine the name variable(s)
# after the first disc has been detected.
#
# This function ends with a cdrom_load_next_cd() call to scan for the
# first disc. For more details about variables read and written by this

# Scan for the first disc.

}
# @FUNCTION: cdrom_load_next_cd
# @DESCRIPTION:
# If multiple arguments were given to cdrom_get_cds() then you can call
# this function to scan for the next disc. This function is also called
# implicitly to scan for the first disc.
#
# The file(s) given to cdrom_get_cds() are scanned for on any mounted
# filesystem that resembles optical media. If no match is found then
# the user is prompted to insert and mount the disc and press enter to
# rescan. This will loop continuously until a match is found or the
# user aborts with Ctrl+C.
#
# The user can override the scan location by setting CD_ROOT for a
# single disc, CD_ROOT if multiple discs are merged into the same
# directory tree (useful for existing installations), or individual
# CD_ROOT_# variables for each disc starting from 1. If no match is
# found then the function dies with an error as a rescan will not help
# in this instance.
#
# Users wanting to set CD_ROOT or CD_ROOT_# for specific packages
# persistently can do so using Portage's /etc/portage/env feature.
#
# Regardless of which scanning method is used, several variables are set
# by this function for you to use:
#
# CDROM_ROOT: Root path of the detected disc.
# CDROM_MATCH: Path of the matched file, relative to CDROM_ROOT.
# CDROM_ABSMATCH: Absolute path of the matched file.
# CDROM_SET: The matching set number, starting from 0.
#
# The casing of CDROM_MATCH may not be the same as the argument given to
# cdrom_get_cds() as matching is done case-insensitively. You should
# therefore use this variable (or CDROM_ABSMATCH) when performing file
# operations to ensure the file is found. Use newins rather than doins
# to keep the final result consistent and take advantage of Bash
# case-conversion features like ${FOO,,}.
#
# Chances are that you'll need more than just the matched file from each
# disc though. You should not assume the casing of these files either
# but dealing with this goes beyond the scope of this ebuild. For a
# good example, see games-action/descent2-data, which combines advanced
# globbing with advanced tar features to concisely deal with
# case-insensitive matching, case conversion, file moves, and
# conditional exclusion.
#
# Copying directly from a mounted disc using doins/newins will remove
# any read-only permissions but be aware of these when copying to an
# intermediate directory first. Attempting to clean a build directory
# containing read-only files as a non-root user will result in an error.
# If you're using tar as suggested above then you can easily work around
# this with --mode=u+w.
#
# Note that you can only go forwards in the disc list, so make sure you
# only call this function when you're done using the current disc.
#
# If you cd to any location within CDROM_ROOT then remember to leave the
# directory before calling this function again, otherwise the user won't
# be able to unmount the current disc.

# @DESCRIPTION:
# The cmake-multilib.eclass provides a glue between cmake-utils.eclass(5)

# to build packages using cmake for multiple ABIs.
#
# Inheriting this eclass sets IUSE and exports default multilib_src_*()
# sub-phases that call cmake-utils phase functions for each ABI enabled.
# The multilib_src_*() functions can be defined in ebuild just like
# in multilib-minimal, yet they ought to call appropriate cmake-utils
# phase rather than 'default'.
# @ECLASS-VARIABLE: CMAKE_ECLASS
# @DESCRIPTION:
# Default is "cmake-utils" for compatibility. Specify "cmake" for ebuilds
# that ported from cmake-utils.eclass to cmake.eclass already.

# @BLURB: common ebuild functions for cmake-based packages
# @DESCRIPTION:
# DEPRECATED: This no longer receives any changes. Everyone must port to cmake.eclass.
# The cmake-utils eclass makes creating ebuilds for cmake-based packages much easier.
# It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with out-of-source
# builds (default), in-source builds and an implementation of the well-known use_enable
# and use_with functions for CMake.

# @ECLASS-VARIABLE: BUILD_DIR
# @DESCRIPTION:
# Build directory where all cmake processed files should be generated.
# For in-source build it's fixed to ${CMAKE_USE_DIR}.
# For out-of-source build it can be overridden, by default it uses
# ${WORKDIR}/${P}_build.
#
# This variable has been called CMAKE_BUILD_DIR formerly.
# It is set under that name for compatibility.
# @ECLASS-VARIABLE: CMAKE_BINARY
# @DESCRIPTION:
# Eclass can use different cmake binary than the one provided in by system.
: ${CMAKE_BINARY:=cmake}
# @ECLASS-VARIABLE: CMAKE_BUILD_TYPE
# @DESCRIPTION:
# Set to override default CMAKE_BUILD_TYPE. Only useful for packages
# known to make use of "if (CMAKE_BUILD_TYPE MATCHES xxx)".
# If about to be set - needs to be set before invoking cmake-utils_src_configure.
# You usualy do *NOT* want nor need to set it as it pulls CMake default build-type
# specific compiler flags overriding make.conf.
: ${CMAKE_BUILD_TYPE:=Gentoo}
# @ECLASS-VARIABLE: CMAKE_IN_SOURCE_BUILD
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set to enable in-source build.
# @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specify a makefile generator to be used by cmake.
# At this point only "emake" and "ninja" are supported.
# In EAPI 7 and above, the default is set to "ninja",
# whereas in EAPIs below 7, it is set to "emake".
# @ECLASS-VARIABLE: CMAKE_MIN_VERSION
# @DESCRIPTION:
# Specify the minimum required CMake version.
: ${CMAKE_MIN_VERSION:=3.9.6}
# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES
# @DESCRIPTION:
# Do we want to remove anything? yes or whatever else for no
: ${CMAKE_REMOVE_MODULES:=yes}
# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
# @DESCRIPTION:
# Space-separated list of CMake modules that will be removed in $S during src_prepare,
# in order to force packages to use the system version.
: ${CMAKE_REMOVE_MODULES_LIST:=FindBLAS FindLAPACK}
# @ECLASS-VARIABLE: CMAKE_USE_DIR
# @DESCRIPTION:
# Sets the directory where we are working with cmake.
# For example when application uses autotools and only one
# plugin needs to be done by cmake.
# By default it uses ${S}.
# @ECLASS-VARIABLE: CMAKE_VERBOSE
# @DESCRIPTION:
# Set to OFF to disable verbose messages during compilation
: ${CMAKE_VERBOSE:=ON}
# @ECLASS-VARIABLE: CMAKE_WARN_UNUSED_CLI
# @DESCRIPTION:
# Warn about variables that are declared on the command line
# but not used. Might give false-positives.
# "no" to disable (default) or anything else to enable.
# @ECLASS-VARIABLE: CMAKE_EXTRA_CACHE_FILE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specifies an extra cache file to pass to cmake. This is the analog of EXTRA_ECONF
# for econf and is needed to pass TRY_RUN results when cross-compiling.
# Should be set by user in a per-package basis in /etc/portage/package.env.
# @ECLASS-VARIABLE: CMAKE_UTILS_QA_SRC_DIR_READONLY
# @DEFAULT_UNSET
# @DESCRIPTION:
# After running cmake-utils_src_prepare, sets ${S} to read-only. This is
# a user flag and should under _no circumstances_ be set in the ebuild.
# Helps in improving QA of build systems that write to source tree.

# @SUPPORTED_EAPIS: 7
# @BLURB: common ebuild functions for cmake-based packages
# @DESCRIPTION:
# The cmake eclass makes creating ebuilds for cmake-based packages much easier.
# It provides all inherited features (DOCS, HTML_DOCS, PATCHES) along with
# out-of-source builds (default), in-source builds and an implementation of the
# well-known use_enable function for CMake.
if [[ -z ${_CMAKE_ECLASS} ]]; then
_CMAKE_ECLASS=1
# @ECLASS-VARIABLE: BUILD_DIR
# @DESCRIPTION:
# Build directory where all cmake processed files should be generated.
# For in-source build it's fixed to ${CMAKE_USE_DIR}.
# For out-of-source build it can be overridden, by default it uses
# ${WORKDIR}/${P}_build.
: ${BUILD_DIR:=${WORKDIR}/${P}_build}
# @ECLASS-VARIABLE: CMAKE_BINARY
# @DESCRIPTION:
# Eclass can use different cmake binary than the one provided in by system.
: ${CMAKE_BINARY:=cmake}
# @ECLASS-VARIABLE: CMAKE_BUILD_TYPE
# @DESCRIPTION:
# Set to override default CMAKE_BUILD_TYPE. Only useful for packages
# known to make use of "if (CMAKE_BUILD_TYPE MATCHES xxx)".
# If about to be set - needs to be set before invoking cmake_src_configure.
# You usually do *NOT* want nor need to set it as it pulls CMake default
# build-type specific compiler flags overriding make.conf.
: ${CMAKE_BUILD_TYPE:=Gentoo}
# @ECLASS-VARIABLE: CMAKE_IN_SOURCE_BUILD
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set to enable in-source build.
# @ECLASS-VARIABLE: CMAKE_MAKEFILE_GENERATOR
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specify a makefile generator to be used by cmake.
# At this point only "emake" and "ninja" are supported.
# The default is set to "ninja".
: ${CMAKE_MAKEFILE_GENERATOR:=ninja}
# @ECLASS-VARIABLE: CMAKE_REMOVE_MODULES_LIST
# @DESCRIPTION:
# Array of CMake modules that will be removed in $S during src_prepare,
# in order to force packages to use the system version.
# Set to "none" to disable removing modules entirely.
: ${CMAKE_REMOVE_MODULES_LIST:=FindBLAS FindLAPACK}
# @ECLASS-VARIABLE: CMAKE_USE_DIR
# @DESCRIPTION:
# Sets the directory where we are working with cmake, for example when
# application uses autotools and only one plugin needs to be done by cmake.
# By default it uses ${S}.
# @ECLASS-VARIABLE: CMAKE_VERBOSE
# @DESCRIPTION:
# Set to OFF to disable verbose messages during compilation
: ${CMAKE_VERBOSE:=ON}
# @ECLASS-VARIABLE: CMAKE_WARN_UNUSED_CLI
# @DESCRIPTION:
# Warn about variables that are declared on the command line
# but not used. Might give false-positives.
# "no" to disable (default) or anything else to enable.
: ${CMAKE_WARN_UNUSED_CLI:=yes}
# @ECLASS-VARIABLE: CMAKE_EXTRA_CACHE_FILE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Specifies an extra cache file to pass to cmake. This is the analog of EXTRA_ECONF
# for econf and is needed to pass TRY_RUN results when cross-compiling.
# Should be set by user in a per-package basis in /etc/portage/package.env.
# @ECLASS-VARIABLE: CMAKE_QA_SRC_DIR_READONLY
# @DEFAULT_UNSET
# @DESCRIPTION:
# After running cmake_src_prepare, sets ${S} to read-only. This is
# a user flag and should under _no circumstances_ be set in the ebuild.
# Helps in improving QA of build systems that write to source tree.

# ebuild, set the ECLASS VARIABLES as specified below in your ebuild before

# @BLURB: Functions to allow ebuilds to depend on apache
# @DESCRIPTION:
# This eclass handles depending on apache in a sane way and provides information
# about where certain binaries and configuration files are located.
#
# To make use of this eclass simply call one of the need/want_apache functions
# described below. Make sure you use the need/want_apache call after you have
# defined DEPEND and RDEPEND. Also note that you can not rely on the automatic
# RDEPEND=DEPEND that portage does if you use this eclass.
#
# See Bug 107127 for more information.
#
# @EXAMPLE:
#
# Here is an example of an ebuild depending on apache:
#
# @CODE
# DEPEND="virtual/Perl-CGI"
# RDEPEND="${DEPEND}"
# need_apache2
# @CODE
#
# Another example which demonstrates non-standard IUSE options for optional
# apache support:
#
# @CODE
# DEPEND="server? ( virtual/Perl-CGI )"
# RDEPEND="${DEPEND}"
# want_apache2 server
#
# pkg_setup() {
# depend.apache_pkg_setup server

# @BLURB: A simple eclass to build documentation.
# @DESCRIPTION:
# A simple eclass providing basic functions and variables to build
# documentation.
#
# Please note that this eclass appends to RDEPEND and DEPEND
# unconditionally for you.
#
# This eclass also appends "doc" to IUSE, and sets HTML_DOCS
# to the location of the compiled documentation automatically,
# 'einstalldocs' will then automatically install the documentation
# to the correct directory.
#
# The aim of this eclass is to make it easy to add additional
# doc builders. To do this, add a <DOCS_BUILDER>_deps and
# <DOCS_BUILDER>_compile function for your doc builder.
# For python based doc builders you can use the
# python_append_deps function to append [${PYTHON_USEDEP}]
# automatically to additional dependencies.
#
# Example use doxygen:
# @CODE
# DOCS_BUILDER="doxygen"
# DOCS_DEPEND="media-gfx/imagemagick"
# DOCS_DIR="docs"
#
# inherit docs
#
# ...
#
# src_compile() {
# default
# docs_compile
# }
# @CODE
#
# Example use mkdocs with distutils-r1:
# @CODE
# DOCS_BUILDER="mkdocs"
# DOCS_DEPEND="dev-python/mkdocs-material"
# DOCS_DIR="doc"
#
# PYTHON_COMPAT=( python3_{7,8,9} )
#
# inherit distutils-r1 docs
#
# ...

# @DESCRIPTION:
# Sets the doc builder to use, currently supports
# sphinx, mkdocs and doxygen.
# PYTHON_COMPAT should be set for python based
# doc builders: sphinx and mkdocs
# @ECLASS-VARIABLE: DOCS_DIR
# @DESCRIPTION:
# Path containing the doc builder config file(s).
#
# For sphinx this is the location of "conf.py"
#
# For mkdocs this is the location of "mkdocs.yml"
# Note that mkdocs.yml often does not reside
# in the same directory as the actual doc files
#
# For doxygen the default name is Doxyfile, but
# package may use a non-standard name. If this
# is the case one should set DOCS_CONFIG_NAME to
# the correct name
#
# Defaults to ${S}
# @ECLASS-VARIABLE: DOCS_DEPEND
# @DEFAULT_UNSET
# @PRE_INHERIT
# @DESCRIPTION:
# Sets additional dependencies required to build the
# documentation.
# For sphinx and mkdocs these dependencies should
# be specified *without* [${PYTHON_USEDEP}], this
# is added by the eclass. E.g. to depend on mkdocs-material:
#
# @CODE
# DOCS_DEPEND="dev-python/mkdocs-material"
# @CODE
#
# This eclass appends to this variable, this makes it
# possible to call it later in your ebuild again if
# necessary.
# @ECLASS-VARIABLE: DOCS_AUTODOC
# @PRE_INHERIT
# @DESCRIPTION:
# Sets whether to use sphinx.ext.autodoc/mkautodoc
# Defaults to 1 (True) for sphinx, and 0 (False) for mkdocs.
# Not relevant for doxygen.
# @ECLASS-VARIABLE: DOCS_OUTDIR
# @DESCRIPTION:
# Sets the directory where the documentation should
# be built into. There is no real reason to change this.
# However, this variable is useful if the package should
# also install other HTML files.
#
# Example use:
# @CODE
# HTML_DOCS=( "${yourdocs}" "${DOCS_OUTDIR}/." )
# @CODE
#
# Defaults to ${S}/_build/html
# @ECLASS-VARIABLE: DOCS_CONFIG_NAME
# @DESCRIPTION:
# Name of the doc builder config file.
#
# Only relevant for doxygen, as it allows
# config files with non-standard names.
# Does not do anything for mkdocs or sphinx.

# it manually. Note that this function checks if USE="doc" is
# enabled, and if not automatically exits. Therefore, there is
# no need to wrap this function in a if statement.
#
# Example use:
# @CODE
# src_compile() {
# default
# docs_compile
# }
# @CODE
docs_compile() {

# @BLURB: Testing implementation of EAPI 7 version manipulators
# @DESCRIPTION:
# A stand-alone implementation of the version manipulation functions
# aimed for EAPI 7. Intended to be used for wider testing of
# the proposed functions and to allow ebuilds to switch to the new
# model early, with minimal change needed for actual EAPI 7.
#
# https://bugs.gentoo.org/482170
#
# @SUBSECTION Version strings
#
# The functions support arbitrary version strings consisting of version
# components interspersed with (possibly empty) version separators.
#
# A version component can either consist purely of digits ([0-9]+)
# or purely of uppercase and lowercase letters ([A-Za-z]+). A version
# separator is either a string of any other characters ([^A-Za-z0-9]+),
# or it occurs at the transition between a sequence of letters
# and a sequence of digits, or vice versa. In the latter case,
# the version separator is an empty string.
#
# The version is processed left-to-right, and each successive component
# is assigned numbers starting with 1. The components are either split
# on version separators or on boundaries between digits and letters
# (in which case the separator between the components is empty).
# Version separators are assigned numbers starting with 1 for
# the separator between 1st and 2nd components. As a special case,
# if the version string starts with a separator, it is assigned index 0.
#
# Examples:
#
# @CODE
# 1.2b-alpha4 -> 1 . 2 '' b - alpha '' 4
# c s c s c s c s c
# 1 1 2 2 3 3 4 4 5
#
# .11. -> . 11 .
# s c s
# 0 1 1
# @CODE
#
# @SUBSECTION Ranges
#
# A range can be specified as 'm' for m-th version component, 'm-'
# for all components starting with m-th or 'm-n' for components starting
# at m-th and ending at n-th (inclusive). If the range spans outside
# the version string, it is truncated silently.

# @BLURB: Emacs-related installation utilities
# @DESCRIPTION:
#
# Usually you want to use this eclass for (optional) GNU Emacs support
# of your package. This is NOT for XEmacs!
#
# Many of the steps here are sometimes done by the build system of your
# package (especially compilation), so this is mainly for standalone
# elisp files you gathered from somewhere else.
#
# When relying on the emacs USE flag, you need to add
#
# @CODE
# emacs? ( >=app-editors/emacs-23.1:* )
# @CODE
#
# to your DEPEND/RDEPEND line and use the functions provided here to
# bring the files to the correct locations.
#
# If your package requires a minimum Emacs version, e.g. Emacs 26.1,
# then the dependency should be on >=app-editors/emacs-26.1:* instead.
# Because the user can select the Emacs executable with eselect, you
# should also make sure that the active Emacs version is sufficient.
# The eclass will automatically ensure this if you assign variable
# NEED_EMACS with the Emacs version, as in the following example:
#
# @CODE
# NEED_EMACS=26.1
# @CODE
#
# Please note that this should be done only for packages that are known
# to fail with lower Emacs versions.
#
# @SUBSECTION src_compile() usage:
#
# An elisp file is compiled by the elisp-compile() function defined
# here and simply takes the source files as arguments. The case of
# interdependent elisp files is also supported, since the current
# directory is added to the load-path which makes sure that all files
# are loadable.
#
# @CODE
# elisp-compile *.el
# @CODE
#
# Function elisp-make-autoload-file() can be used to generate a file
# with autoload definitions for the lisp functions. It takes the output
# file name (default: "${PN}-autoloads.el") and a list of directories
# (default: working directory) as its arguments. Use of this function
# requires that the elisp source files contain magic ";;;###autoload"
# comments. See the Emacs Lisp Reference Manual (node "Autoload") for
# a detailed explanation.
#
# @SUBSECTION src_install() usage:
#
# The resulting compiled files (.elc) should be put in a subdirectory of
# /usr/share/emacs/site-lisp/ which is named after the first argument
# of elisp-install(). The following parameters are the files to be put
# in that directory. Usually the subdirectory should be ${PN}, you can
# choose something else, but remember to tell elisp-site-file-install()
# (see below) the change, as it defaults to ${PN}.
#
# @CODE
# elisp-install ${PN} *.el *.elc
# @CODE
#
# To let the Emacs support be activated by Emacs on startup, you need
# to provide a site file (shipped in ${FILESDIR}) which contains the
# startup code (have a look in the documentation of your software).
# Normally this would look like this:
#
# @CODE
# (add-to-list 'load-path "@SITELISP@")
# (add-to-list 'auto-mode-alist '("\\.csv\\'" . csv-mode))
# (autoload 'csv-mode "csv-mode" "Major mode for csv files." t)
# @CODE
#
# If your Emacs support files are installed in a subdirectory of
# /usr/share/emacs/site-lisp/ (which is strongly recommended), you need
# to extend Emacs' load-path as shown in the first non-comment line.
# The elisp-site-file-install() function of this eclass will replace
# "@SITELISP@" and "@SITEETC@" by the actual paths.
#
# The next line tells Emacs to load the mode opening a file ending
# with ".csv" and load functions depending on the context and needed
# features. Be careful though. Commands as "load-library" or "require"
# bloat the editor as they are loaded on every startup. When having
# many Emacs support files, users may be annoyed by the start-up time.
# Also avoid keybindings as they might interfere with the user's
# settings. Give a hint in pkg_postinst(), which should be enough.
# The guiding principle is that emerging your package should not by
# itself cause a change of standard Emacs behaviour.
#
# The naming scheme for this site-init file matches the shell pattern
# "[1-8][0-9]*-gentoo*.el", where the two digits at the beginning define
# the loading order (numbers below 10 or above 89 are reserved for
# internal use). So if your initialisation depends on another Emacs
# package, your site file's number must be higher! If there are no such
# interdependencies then the number should be 50. Otherwise, numbers
# divisible by 10 are preferred.
#
# Best practice is to define a SITEFILE variable in the global scope of
# your ebuild (e.g., right after S or RDEPEND):
#
# @CODE
# SITEFILE="50${PN}-gentoo.el"
# @CODE
#
# Which is then installed by
#
# @CODE
# elisp-site-file-install "${FILESDIR}/${SITEFILE}"
# @CODE
#
# in src_install(). Any characters after the "-gentoo" part and before
# the extension will be stripped from the destination file's name.
# For example, a file "50${PN}-gentoo-${PV}.el" will be installed as
# "50${PN}-gentoo.el". If your subdirectory is not named ${PN}, give
# the differing name as second argument.
#
# @SUBSECTION pkg_setup() usage:
#
# If your ebuild uses the elisp-compile eclass function to compile
# its elisp files (see above), then you don't need a pkg_setup phase,
# because elisp-compile and elisp-make-autoload-file do their own sanity
# checks. On the other hand, if the elisp files are compiled by the
# package's build system, then there is often no check for the Emacs
# version. In this case, you can add an explicit check in pkg_setup:
#
# @CODE
# elisp-check-emacs-version
# @CODE
#
# When having optional Emacs support, you should prepend "use emacs &&"
# to above call of elisp-check-emacs-version().
#
# @SUBSECTION pkg_postinst() / pkg_postrm() usage:
#
# After that you need to recreate the start-up file of Emacs after
# emerging and unmerging by using
#
# @CODE
# pkg_postinst() {
# elisp-site-regen
# }
#
# pkg_postrm() {
# elisp-site-regen
# }
# @CODE
#
# Again, with optional Emacs support, you should prepend "use emacs &&"
# to above calls of elisp-site-regen().

# @BLURB: Eclass for Emacs Lisp packages
# @DESCRIPTION:
#
# This eclass is designed to install elisp files of Emacs related
# packages into the site-lisp directory. The majority of elisp packages
# will only need to define the standard ebuild variables (like SRC_URI)
# and optionally SITEFILE for successful installation.
#
# Emacs support for other than pure elisp packages is handled by
# elisp-common.eclass where you won't have a dependency on Emacs itself.
# All elisp-* functions are documented there.
#
# If the package's source is a single (in whatever way) compressed elisp
# file with the file name ${P}.el, then this eclass will move ${P}.el to
# ${PN}.el in src_unpack().
# @ECLASS-VARIABLE: NEED_EMACS
# @DEFAULT_UNSET
# @DESCRIPTION:
# If you need anything different from Emacs 23, use the NEED_EMACS
# variable before inheriting elisp.eclass. Set it to the version your
# package uses and the dependency will be adjusted.
# @ECLASS-VARIABLE: ELISP_PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# Space separated list of patches to apply after unpacking the sources.
# Patch files are searched for in the current working dir, WORKDIR, and
# FILESDIR. This variable is semi-deprecated, preferably use the
# PATCHES array instead if the EAPI supports it.
# @ECLASS-VARIABLE: ELISP_REMOVE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Space separated list of files to remove after unpacking the sources.
# @ECLASS-VARIABLE: SITEFILE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Name of package's site-init file. The filename must match the shell
# pattern "[1-8][0-9]*-gentoo.el"; numbers below 10 and above 89 are
# reserved for internal use. "50${PN}-gentoo.el" is a reasonable choice
# in most cases.
# @ECLASS-VARIABLE: ELISP_TEXINFO
# @DEFAULT_UNSET
# @DESCRIPTION:
# Space separated list of Texinfo sources. Respective GNU Info files
# will be generated in src_compile() and installed in src_install().

# Any options specified that start with a dash will be passed down to patch
# for this specific invocation. As soon as an arg w/out a dash is found, then
# arg processing stops.

# of these three directories to exist will be the one to use, ignoring
# any more general directories which might exist as well. They must end
# in ".patch" to be applied.
#
# User patches are intended for quick testing of patches without ebuild
# modifications, as well as for permanent customizations a user might
# desire. Obviously, there can be no official support for arbitrarily
# patched ebuilds. So whenever a build log in a bug report mentions that
# user patches were applied, the user should be asked to reproduce the
# problem without these.
#
# Not all ebuilds do call this function, so placing patches in the
# stated directory might or might not work, depending on the package and
# the eclasses it inherits and uses. It is safe to call the function
# repeatedly, so it is always possible to add a call at the ebuild
# level. The first call is the time when the patches will be
# applied.
#
# Ideally, this function should be called after gentoo-specific patches
# have been applied, so that their code can be modified as well, but
# before calls to e.g. eautoreconf, as the user patches might affect
# autotool input files as well.

# may be used with variables/arguments to custom functions. That would be:

# @BLURB: function to set POSIX file-based capabilities
# @DESCRIPTION:
# This eclass provides a function to set file-based capabilities on binaries.
# This is not the same as USE=caps which controls runtime capability changes,
# often via packages like libcap.
#
# Due to probable capability-loss on moving or copying, this happens in
# pkg_postinst phase (at least for now).
#
# @EXAMPLE:
# You can manually set the caps on ping and ping6 by doing:
# @CODE
# pkg_postinst() {
# fcaps cap_net_raw bin/ping bin/ping6
# }
# @CODE
#
# Or set it via the global ebuild var FILECAPS:
# @CODE
# FILECAPS=(
# cap_net_raw bin/ping bin/ping6
# )
# @CODE

# @ECLASS-VARIABLE: FILECAPS
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array of fcap arguments to use to automatically execute fcaps. See that
# function for more details.
#
# All args are consumed until the '--' marker is found. So if you have:
# @CODE
# FILECAPS=( moo cow -- fat cat -- chubby penguin )
# @CODE
#
# This will end up executing:
# @CODE
# fcaps moo cow
# fcaps fat cat
# fcaps chubby penguin
# @CODE
#
# Note: If you override pkg_postinst, you must call fcaps_pkg_postinst yourself.
# @FUNCTION: fcaps
# @USAGE: [-o <owner>] [-g <group>] [-m <mode>] [-M <caps mode>] <capabilities> <file[s]>
# @DESCRIPTION:
# Sets the specified capabilities on the specified files.
#
# The caps option takes the form as expected by the cap_from_text(3) man page.
# If no action is specified, then "=ep" will be used as a default.
#
# If the file is a relative path (e.g. bin/foo rather than /bin/foo), then the
# appropriate path var ($D/$ROOT/etc...) will be prefixed based on the current
# ebuild phase.
#
# The caps mode (default 711) is used to set the permission on the file if
# capabilities were properly set on the file.
#
# If the system is unable to set capabilities, it will use the specified user,
# group, and mode (presumably to make the binary set*id). The defaults there
# are root:0 and 4711. Otherwise, the ownership and permissions will be
# unchanged.

# @BLURB: basic eclass for building software written as go modules
# @DESCRIPTION:
# This eclass provides basic settings and functions needed by all software
# written in the go programming language that uses modules.
#
# If the software you are packaging has a file named go.mod in its top
# level directory, it uses modules and your ebuild should inherit this
# eclass. If it does not, your ebuild should use the golang-* eclasses.
#
# If, besides go.mod, your software has a directory named vendor in its
# top level directory, the only thing you need to do is inherit the
# eclass. If there is no vendor directory, you need to also populate
# EGO_SUM and call go-module_set_globals as discussed below.
#
# Since Go programs are statically linked, it is important that your ebuild's
# LICENSE= setting includes the licenses of all statically linked
# dependencies. So please make sure it is accurate.
# You can use a utility like dev-util/golicense (network connectivity is
# required) to extract this information from the compiled binary.
#
# @EXAMPLE:
#
# @CODE
#
# inherit go-module

# @ECLASS-VARIABLE: EGO_SUM
# @DESCRIPTION:
# This is an array based on the go.sum content from inside the target package.
# Each array entry must be quoted and contain information from a single
# line from go.sum.
#
# The format of go.sum is described upstream here:
# https://tip.golang.org/cmd/go/#hdr-Module_authentication_using_go_sum
#
# For inclusion in EGO_SUM, the h1: value and other future extensions SHOULD be
# omitted at this time. The EGO_SUM parser will accept them for ease of ebuild
# creation.
#
# h1:<hash> is the Hash1 structure used by upstream Go
# The Hash1 is MORE stable than Gentoo distfile hashing, and upstream warns
# that it's conceptually possible for the Hash1 value to remain stable while
# the upstream zipfiles change. Here are examples that do NOT change the h1:
# hash, but do change a regular checksum over all bytes of the file:
# - Differing mtimes within zipfile
# - Differing filename ordering with the zipfile
# - Differing zipfile compression parameters
# - Differing zipfile extra fields
#
# For Gentoo usage, the authors of this eclass feel that the h1: hash should
# NOT be included in the EGO_SUM at this time in order to reduce size of the
# ebuilds. This position will be reconsidered in future when a Go module
# distfile collision comes to light, where the Hash1 value of two distfiles is
# the same, but checksums over the file as a byte stream consider the files to
# be different.
#
# This decision does NOT weaken Go module security, as Go will verify the
# go.sum copy of the Hash1 values during building of the package.
# @ECLASS-VARIABLE: _GOMODULE_GOPROXY_BASEURI
# @DESCRIPTION:
# Golang module proxy service to fetch module files from. Note that the module
# proxy generally verifies modules via the Hash1 code.
#
# Users in China may find some mirrors in the default list blocked, and should
# explicitly set an entry in /etc/portage/mirrors for goproxy to
# https://goproxy.cn/ or another mirror that is not blocked in China.
# See https://arslan.io/2019/08/02/why-you-should-use-a-go-module-proxy/ for
# further details
#
# This variable is NOT intended for user-level configuration of mirrors, but
# rather to cover go modules that might exist only on specific Goproxy
# servers for non-technical reasons.
#
# This variable should NOT be present in user-level configuration e.g.
# /etc/portage/make.conf, as it will violate metadata immutability!
#
# I am considering removing this and just hard coding mirror://goproxy
# below, so please do not rely on it.

# @DESCRIPTION:
# Eclass to make external gst-plugins emergable on a per-plugin basis
# and to solve the problem with gst-plugins generating far too much
# unneeded dependencies.
#
# GStreamer consuming applications should depend on the specific plugins
# they need as defined in their source code. Usually you can find that
# out by grepping the source tree for 'factory_make'. If it uses playbin
# plugin, consider adding media-plugins/gst-plugins-meta dependency, but
# also list any packages that provide explicitly requested plugins.

# @DESCRIPTION:
# Basic instructions:
#
# Before inheriting the eclass, set CABAL_FEATURES to
# reflect the tools and features that the package makes
# use of.
#
# Currently supported features:
# haddock -- for documentation generation
# hscolour -- generation of colourised sources
# hoogle -- generation of documentation search index
# profile -- if package supports to build profiling-enabled libraries
# bootstrap -- only used for the cabal package itself
# lib -- the package installs libraries
# nocabaldep -- don't add dependency on cabal.
# only used for packages that _must_ not pull the dependency
# on cabal, but still use this eclass (e.g. haskell-updater).
# ghcdeps -- constraint dependency on package to ghc onces
# only used for packages that use libghc internally and _must_
# not pull upper versions
# test-suite -- add support for cabal test-suites (introduced in Cabal-1.8)
# rebuild-after-doc-workaround -- enable doctest test failue workaround.
# Symptom: when `./setup haddock` is run in a `build-type: Custom`
# package it might cause cause the test-suite to fail with
# errors like:
# > <command line>: cannot satisfy -package-id singletons-2.7-3Z7pnljD8tU1NrslJodXmr
# Workaround re-reginsters the package to avoid the failure
# (and rebuilds changes).
# FEATURE can be removed once https://github.com/haskell/cabal/issues/7213
# is fixed.

# @BLURB: eclass for ant based Java packages
# @DESCRIPTION:
# Eclass for Ant-based Java packages. Provides support for both automatic and
# manual manipulation of build.xml files. Should be inherited after java-pkg-2
# or java-pkg-opt-2 eclass.
inherit java-utils-2 multilib
# This eclass provides functionality for Java packages which use
# ant to build. In particular, it will attempt to fix build.xml files, so that
# they use the appropriate 'target' and 'source' attributes.
# @ECLASS-VARIABLE: WANT_ANT_TASKS
# @DEFAULT_UNSET
# @DESCRIPTION:
# An $IFS separated list of ant tasks.
# Ebuild can specify this variable before inheriting java-ant-2 eclass to
# determine ANT_TASKS it needs. They will be automatically translated to
# DEPEND variable and ANT_TASKS variable. JAVA_PKG_FORCE_ANT_TASKS can override
# ANT_TASKS set by WANT_ANT_TASKS, but not the DEPEND due to caching.
# Ebuilds that need to depend conditionally on certain tasks and specify them
# differently for different eant calls can't use this simplified approach.
# You also cannot specify version or anything else than ant-*.
#
# @CODE
# WANT_ANT_TASKS="ant-junit ant-trax"

# Example: PLOCALE_BACKUP="en_US"
# @FUNCTION: l10n_for_each_locale_do
# @USAGE: <function>
# @DESCRIPTION:
# Convenience function for processing localizations. The parameter should

# @BLURB: An eclass for easy installation of LaTeX packages
# @DESCRIPTION:
# This eClass is designed to be easy to use and implement. The vast majority of
# LaTeX packages will only need to define SRC_URI (and sometimes S) for a
# successful installation. If fonts need to be installed, then the variable
# SUPPLIER must also be defined.
#
# However, those packages that contain subdirectories must process each
# subdirectory individually. For example, a package that contains directories
# DIR1 and DIR2 must call latex-package_src_compile() and
# latex-package_src_install() in each directory, as shown here:
#
# src_compile() {
# cd ${S}
# cd DIR1
# latex-package_src_compile
# cd ..
# cd DIR2
# latex-package_src_compile
# }
#
# src_install() {
# cd ${S}
# cd DIR1
# latex-package_src_install
# cd ..
# cd DIR2
# latex-package_src_install
# }
#
# The eClass automatically takes care of rehashing TeX's cache (ls-lR) after
# installation and after removal, as well as creating final documentation from
# TeX files that come with the source. Note that we break TeX layout standards
# by placing documentation in /usr/share/doc/${PN}
#
# For examples of basic installations, check out dev-tex/aastex and
# dev-tex/leaflet .
#
# NOTE: The CTAN "directory grab" function creates files with different MD5
# signatures EVERY TIME. For this reason, if you are grabbing from the CTAN,
# you must either grab each file individually, or find a place to mirror an
# archive of them. (iBiblio)

# @AUTHOR:
# Original author: John Mylchreest <johnm@gentoo.org>
# @BLURB: eclass used for accessing kernel related information
# @DESCRIPTION:
# This eclass is used as a central eclass for accessing kernel
# related information for source or binary already installed.
# It is vital for linux-mod.eclass to function correctly, and is split
# out so that any ebuild behaviour "templates" are abstracted out
# using additional eclasses.
#
# "kernel config" in this file means:
# The .config of the currently installed sources is used as the first
# preference, with a fall-back to bundled config (/proc/config.gz) if available.
#
# Before using any of the config-handling functions in this eclass, you must
# ensure that one of the following functions has been called (in order of
# preference), otherwise you will get bugs like #364041):
# linux-info_pkg_setup
# linux-info_get_any_version
# get_version
# get_running_version
# A Couple of env vars are available to effect usage of this eclass
# These are as follows:
# @ECLASS-VARIABLE: KERNEL_DIR
# @DESCRIPTION:
# A string containing the directory of the target kernel sources. The default value is
# "/usr/src/linux"
# @ECLASS-VARIABLE: CONFIG_CHECK
# @DESCRIPTION:
# A string containing a list of .config options to check for before
# proceeding with the install.
#
# e.g.: CONFIG_CHECK="MTRR"
#
# You can also check that an option doesn't exist by
# prepending it with an exclamation mark (!).
#
# e.g.: CONFIG_CHECK="!MTRR"
#
# To simply warn about a missing option, prepend a '~'.
# It may be combined with '!'.
#
# In general, most checks should be non-fatal. The only time fatal checks should
# be used is for building kernel modules or cases that a compile will fail
# without the option.
#
# This is to allow usage of binary kernels, and minimal systems without kernel
# sources.
# @ECLASS-VARIABLE: ERROR_<CFG>
# @DESCRIPTION:
# A string containing the error message to display when the check against CONFIG_CHECK
# fails. <CFG> should reference the appropriate option used in CONFIG_CHECK.
#
# e.g.: ERROR_MTRR="MTRR exists in the .config but shouldn't!!"
# @ECLASS-VARIABLE: KBUILD_OUTPUT
# @DESCRIPTION:
# A string passed on commandline, or set from the kernel makefile. It contains the directory
# which is to be used as the kernel object directory.
# There are also a couple of variables which are set by this, and shouldn't be
# set by hand. These are as follows:
# @ECLASS-VARIABLE: KV_FULL
# @DESCRIPTION:
# A read-only variable. It's a string containing the full kernel version. ie: 2.6.9-gentoo-johnm-r1
# @ECLASS-VARIABLE: KV_MAJOR
# @DESCRIPTION:
# A read-only variable. It's an integer containing the kernel major version. ie: 2
# @ECLASS-VARIABLE: KV_MINOR
# @DESCRIPTION:
# A read-only variable. It's an integer containing the kernel minor version. ie: 6

# Stefan Schweizer <genstef@gentoo.org>
# @BLURB: It provides the functionality required to install external modules against a kernel source tree.
# @DESCRIPTION:
# This eclass is used to interface with linux-info.eclass in such a way
# to provide the functionality and initial functions
# required to install external modules against a kernel source
# tree.
# A Couple of env vars are available to effect usage of this eclass
# These are as follows:
# @ECLASS-VARIABLE: MODULES_OPTIONAL_USE
# @DESCRIPTION:
# A string containing the USE flag to use for making this eclass optional
# The recommended non-empty value is 'modules'
# @ECLASS-VARIABLE: MODULES_OPTIONAL_USE_IUSE_DEFAULT
# @DESCRIPTION:
# A boolean to control the IUSE default state for the MODULES_OPTIONAL_USE USE
# flag. Default value is unset (false). True represented by 1 or 'on', other
# values including unset treated as false.
# @ECLASS-VARIABLE: KERNEL_DIR
# @DESCRIPTION:
# A string containing the directory of the target kernel sources. The default value is
# "/usr/src/linux"
# @ECLASS-VARIABLE: ECONF_PARAMS
# @DESCRIPTION:
# It's a string containing the parameters to pass to econf.
# If this is not set, then econf isn't run.
# @ECLASS-VARIABLE: BUILD_PARAMS
# @DESCRIPTION:
# It's a string with the parameters to pass to emake.
# @ECLASS-VARIABLE: BUILD_TARGETS
# @DESCRIPTION:
# It's a string with the build targets to pass to make. The default value is "clean module"
# @ECLASS-VARIABLE: MODULE_NAMES
# @DESCRIPTION:
# It's a string containing the modules to be built automatically using the default
# src_compile/src_install. It will only make ${BUILD_TARGETS} once in any directory.
#
# The structure of each MODULE_NAMES entry is as follows:
#
# modulename(libdir:srcdir:objdir)
#
# where:
#
# modulename = name of the module file excluding the .ko
# libdir = place in system modules directory where module is installed (by default it's misc)
# srcdir = place for ebuild to cd to before running make (by default it's ${S})
# objdir = place the .ko and objects are located after make runs (by default it's set to srcdir)
#
# To get an idea of how these variables are used, here's a few lines
# of code from around line 540 in this eclass:
#
# einfo "Installing ${modulename} module"
# cd ${objdir} || die "${objdir} does not exist"
# insinto /lib/modules/${KV_FULL}/${libdir}
# doins ${modulename}.${KV_OBJ} || die "doins ${modulename}.${KV_OBJ} failed"
#
# For example:
# MODULE_NAMES="module_pci(pci:${S}/pci:${S}) module_usb(usb:${S}/usb:${S})"
#
# what this would do is
#
# cd "${S}"/pci
# make ${BUILD_PARAMS} ${BUILD_TARGETS}
# cd "${S}"
# insinto /lib/modules/${KV_FULL}/pci
# doins module_pci.${KV_OBJ}
#
# cd "${S}"/usb
# make ${BUILD_PARAMS} ${BUILD_TARGETS}
# cd "${S}"
# insinto /lib/modules/${KV_FULL}/usb
# doins module_usb.${KV_OBJ}
# There is also support for automated modprobe.d file generation.
# This can be explicitly enabled by setting any of the following variables.
# @ECLASS-VARIABLE: MODULESD_<modulename>_ENABLED
# @DESCRIPTION:
# This is used to disable the modprobe.d file generation otherwise the file will be
# always generated (unless no MODULESD_<modulename>_* variable is provided). Set to "no" to disable
# the generation of the file and the installation of the documentation.
# @ECLASS-VARIABLE: MODULESD_<modulename>_EXAMPLES
# @DESCRIPTION:
# This is a bash array containing a list of examples which should
# be used. If you want us to try and take a guess set this to "guess".
#
# For each array_component it's added an options line in the modprobe.d file
#
# options array_component
#
# where array_component is "<modulename> options" (see modprobe.conf(5))
# @ECLASS-VARIABLE: MODULESD_<modulename>_ALIASES
# @DESCRIPTION:
# This is a bash array containing a list of associated aliases.
#
# For each array_component it's added an alias line in the modprobe.d file
#
# alias array_component
#
# where array_component is "wildcard <modulename>" (see modprobe.conf(5))
# @ECLASS-VARIABLE: MODULESD_<modulename>_ADDITIONS
# @DESCRIPTION:
# This is a bash array containing a list of additional things to
# add to the bottom of the file. This can be absolutely anything.
# Each entry is a new line.
# @ECLASS-VARIABLE: MODULESD_<modulename>_DOCS
# @DESCRIPTION:
# This is a string list which contains the full path to any associated
# documents for <modulename>. These files are installed in the live tree.
# @ECLASS-VARIABLE: KV_OBJ
# @DESCRIPTION:
# It's a read-only variable. It contains the extension of the kernel modules.

# @BLURB: Utility functions to build against slotted LLVM
# @DESCRIPTION:
# The llvm.eclass provides utility functions that can be used to build
# against specific version of slotted LLVM (with fallback to :0 for old
# versions).
#
# This eclass does not generate dependency strings. You need to write
# a proper dependency string yourself to guarantee that appropriate
# version of LLVM is installed.
#
# Example use for a package supporting LLVM 5 to 7:
# @CODE
# inherit cmake-utils llvm
#
# RDEPEND="
# <sys-devel/llvm-8:=
# || (
# sys-devel/llvm:7
# sys-devel/llvm:6
# sys-devel/llvm:5
# )
# "
# DEPEND=${RDEPEND}
#
# LLVM_MAX_SLOT=7
#
# # only if you need to define one explicitly
# pkg_setup() {
# llvm_pkg_setup
# do-something-else
# }
# @CODE
#
# Example for a package needing LLVM+clang w/ a specific target:
# @CODE
# inherit cmake-utils llvm
#
# # note: do not use := on both clang and llvm, it can match different
# # slots then. clang pulls llvm in, so we can skip the latter.
# RDEPEND="
# >=sys-devel/clang-6:=[llvm_targets_AMDGPU(+)]
# "
# DEPEND=${RDEPEND}
#
# llvm_check_deps() {
# has_version -d "sys-devel/clang:${LLVM_SLOT}[llvm_targets_AMDGPU(+)]"

# calls llvm-config executable. -b is supported since EAPI 7.
#
# If -d is specified, the checks are performed relative to ESYSROOT,
# and ESYSROOT-path is returned. This is appropriate when your package
# uses CMake find_package(LLVM). -d is the default.
#
# If <max_slot> is specified, then only LLVM versions that are not newer
# than <max_slot> will be considered. Otherwise, all LLVM versions would
# be considered acceptable. The function does not support specifying
# minimal supported version -- the developer must ensure that a version
# new enough is installed via providing appropriate dependencies.
#
# If llvm_check_deps() function is defined within the ebuild, it will
# be called to verify whether a particular slot is accepable. Within
# the function scope, LLVM_SLOT will be defined to the SLOT value
# (0, 4, 5...). The function should return a true status if the slot
# is acceptable, false otherwise. If llvm_check_deps() is not defined,
# the function defaults to checking whether sys-devel/llvm:${LLVM_SLOT}

# additional components, they need to be listed in LLVM_TEST_COMPONENTS.
# The eclass exports an implementation of src_unpack() phase.
#
# Example:
# @CODE
# inherit llvm.org

# LLVM_COMPONENTS=( lld )
# LLVM_TEST_COMPONENTS=( llvm/utils/lit )
# llvm.org_set_globals

# @DESCRIPTION:
# An extension of lua.eclass suite for packages which don't support being
# installed for multiple Lua implementations. This mostly includes software
# embedding Lua.
#
# This eclass sets correct IUSE. It also provides LUA_DEPS
# and LUA_REQUIRED_USE that need to be added to appropriate ebuild
# metadata variables.
#
# The eclass exports LUA_SINGLE_USEDEP that is suitable for depending
# on other packages using the eclass. Dependencies on packages using
# lua.eclass should be created via lua_gen_cond_dep() function, using
# LUA_USEDEP placeholder.
#
# Please note that packages support multiple Lua implementations
# (using lua.eclass) cannot depend on packages not supporting
# them (using this eclass).
#
# Note that since this eclass always inherits lua-utils as well, in ebuilds
# using the former there is no need to explicitly inherit the latter in order
# to use helper functions such as lua_get_CFLAGS.
#
# @EXAMPLE:
# @CODE
# EAPI=7
#
# LUA_COMPAT=( lua5-{1..3} )
#
# inherit lua-single
#
# [...]
#
# REQUIRED_USE="${LUA_REQUIRED_USE}"

# @DEFAULT_UNSET
# @DESCRIPTION:
# This variable can be used when working with ebuilds to override
# the in-ebuild LUA_COMPAT. It is a string listing all
# the implementations which package will be built for. It need be
# specified in the calling environment, and not in ebuilds.
#
# It should be noted that in order to preserve metadata immutability,
# LUA_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
# The state of LUA_TARGETS is ignored, and all the implementations
# in LUA_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
# manually.
#
# Example:
# @CODE
# LUA_COMPAT_OVERRIDE='lua5-2' emerge -1v dev-lua/foo
# @CODE
# @ECLASS-VARIABLE: LUA_REQ_USE
# @DEFAULT_UNSET
# @PRE_INHERIT
# @DESCRIPTION:
# The list of USE flags required to be enabled on the chosen Lua
# implementations, formed as a USE-dependency string. It should be valid
# for all implementations in LUA_COMPAT, so it may be necessary to
# use USE defaults.
# This must be set before calling `inherit'.
#
# Example:
# @CODE
# LUA_REQ_USE="deprecated"
# @CODE
#
# It will cause the Lua dependencies to look like:
# @CODE
# lua_targets_luaX-Y? ( dev-lang/lua:X.Y[deprecated] )
# @CODE
# @ECLASS-VARIABLE: LUA_DEPS
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated Lua dependency string for all
# implementations listed in LUA_COMPAT.
#
# Example use:
# @CODE
# RDEPEND="${LUA_DEPS}
# dev-foo/mydep"
# DEPEND="${RDEPEND}"
# @CODE
#
# Example value:
# @CODE
# lua_targets_lua5-1? ( dev-lang/lua:5.1 )
# lua_targets_lua5-2? ( dev-lang/lua:5.2 )
# @CODE
# @ECLASS-VARIABLE: LUA_REQUIRED_USE
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated required-use expression which ensures at
# least one Lua implementation has been enabled.
#
# This expression should be utilized in an ebuild by including it in
# REQUIRED_USE, optionally behind a use flag.
#
# Example use:
# @CODE
# REQUIRED_USE="lua? ( ${LUA_REQUIRED_USE} )"
# @CODE
#
# Example value:
# @CODE
# || ( lua_targets_lua5-1 lua_targets_lua5-2 )
# @CODE
# @ECLASS-VARIABLE: LUA_SINGLE_USEDEP
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated USE-dependency string which can be used
# to depend on another lua-single package being built for the same
# Lua implementations.
#
# If you need to depend on a multi-impl (lua.eclass) package, use
# lua_gen_cond_dep with LUA_USEDEP placeholder instead.
#
# Example use:
# @CODE
# RDEPEND="dev-lua/foo[${LUA_SINGLE_USEDEP}]"
# @CODE
#
# Example value:
# @CODE
# lua_single_target_lua5-1(-)?
# @CODE
# @ECLASS-VARIABLE: LUA_USEDEP
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated USE-dependency string which can be used to
# depend on another Lua package being built for the same Lua
# implementations.
#
# Example use:
# @CODE
# RDEPEND="dev-lua/foo[${LUA_USEDEP}]"

# @SUPPORTED_EAPIS: 7
# @BLURB: A common eclass for Lua packages
# @DESCRIPTION:
# A common eclass providing helper functions to build and install
# packages supporting being installed for multiple Lua implementations.
#
# This eclass sets correct IUSE. Modification of REQUIRED_USE has to
# be done by the author of the ebuild (but LUA_REQUIRED_USE is
# provided for convenience, see below). The eclass exports LUA_DEPS
# and LUA_USEDEP so you can create correct dependencies for your
# package easily. It also provides methods to easily run a command for
# each enabled Lua implementation and duplicate the sources for them.
#
# Note that since this eclass always inherits lua-utils as well, in ebuilds
# using the former there is no need to explicitly inherit the latter in order
# to use helper functions such as lua_get_CFLAGS.
#
# @EXAMPLE:
# @CODE
# EAPI=7
#
# LUA_COMPAT=( lua5-{1..3} )
#
# inherit lua
#
# [...]
#
# REQUIRED_USE="${LUA_REQUIRED_USE}"
# DEPEND="${LUA_DEPS}"
# RDEPEND="${DEPEND}
# dev-lua/foo[${LUA_USEDEP}]"
# BDEPEND="virtual/pkgconfig"
#
# lua_src_install() {
# emake LUA_VERSION="$(lua_get_version)" install

# @ECLASS-VARIABLE: LUA_COMPAT
# @REQUIRED
# @PRE_INHERIT
# @DESCRIPTION:
# This variable contains a list of Lua implementations the package
# supports. It must be set before the `inherit' call. It has to be
# an array.
#
# Example:
# @CODE
# LUA_COMPAT=( lua5-1 lua5-2 lua5-3 )
# @CODE
#
# Please note that you can also use bash brace expansion if you like:
# @CODE
# LUA_COMPAT=( lua5-{1..3} )
# @CODE
# @ECLASS-VARIABLE: LUA_COMPAT_OVERRIDE
# @USER_VARIABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# This variable can be used when working with ebuilds to override
# the in-ebuild LUA_COMPAT. It is a string listing all
# the implementations which package will be built for. It need be
# specified in the calling environment, and not in ebuilds.
#
# It should be noted that in order to preserve metadata immutability,
# LUA_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
# The state of LUA_TARGETS is ignored, and all the implementations
# in LUA_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
# manually.
#
# Example:
# @CODE
# LUA_COMPAT_OVERRIDE='lua5-2' emerge -1v dev-lua/foo
# @CODE
# @ECLASS-VARIABLE: LUA_REQ_USE
# @DEFAULT_UNSET
# @PRE_INHERIT
# @DESCRIPTION:
# The list of USE flags required to be enabled on the chosen Lua
# implementations, formed as a USE-dependency string. It should be valid
# for all implementations in LUA_COMPAT, so it may be necessary to
# use USE defaults.
# This must be set before calling `inherit'.
#
# Example:
# @CODE
# LUA_REQ_USE="deprecated"
# @CODE
#
# It will cause the Lua dependencies to look like:
# @CODE
# lua_targets_luaX-Y? ( dev-lang/lua:X.Y[deprecated] )
# @CODE
# @ECLASS-VARIABLE: BUILD_DIR
# @OUTPUT_VARIABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# The current build directory. In global scope, it is supposed to
# contain an initial build directory; if unset, it defaults to ${S}.
#
# In functions run by lua_foreach_impl(), the BUILD_DIR is locally
# set to an implementation-specific build directory. That path is
# created through appending a hyphen and the implementation name
# to the final component of the initial BUILD_DIR.
#
# Example value:
# @CODE
# ${WORKDIR}/foo-1.3-lua5-1
# @CODE
# @ECLASS-VARIABLE: LUA_DEPS
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated Lua dependency string for all
# implementations listed in LUA_COMPAT.
#
# Example use:
# @CODE
# RDEPEND="${LUA_DEPS}
# dev-foo/mydep"
# DEPEND="${RDEPEND}"
# @CODE
#
# Example value:
# @CODE
# lua_targets_lua5-1? ( dev-lang/lua:5.1 )
# lua_targets_lua5-2? ( dev-lang/lua:5.2 )
# @CODE
# @ECLASS-VARIABLE: LUA_REQUIRED_USE
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated required-use expression which ensures at
# least one Lua implementation has been enabled.
#
# This expression should be utilized in an ebuild by including it in
# REQUIRED_USE, optionally behind a use flag.
#
# Example use:
# @CODE
# REQUIRED_USE="lua? ( ${LUA_REQUIRED_USE} )"
# @CODE
#
# Example value:
# @CODE
# || ( lua_targets_lua5-1 lua_targets_lua5-2 )
# @CODE
# @ECLASS-VARIABLE: LUA_USEDEP
# @OUTPUT_VARIABLE
# @DESCRIPTION:
# This is an eclass-generated USE-dependency string which can be used to
# depend on another Lua package being built for the same Lua
# implementations.
#
# Example use:
# @CODE
# RDEPEND="dev-lua/foo[${LUA_USEDEP}]"
# @CODE
#
# Example value:
# @CODE
# lua_targets_lua5-1(-)?,lua_targets_lua5-2(-)?
