[gentoo-dev] [PATCH] texlive-common.eclass: add EAPI 8

[Thomas Bracht Laumann Jespersen]

As an initial step in the work to add texlive 2023, let's start with adding EAPI
8 support to texlive-common.eclass.

Needs a consideration for dosym -r in one place, and also changes a test block
with single brackets to double brackets.

The quotes are no longer needed in [[ ]].

ack. Will include in a v2.

I'll also add a patch to add EAPI 8 to texlive-module.eclass.

v1 -> v2:

 * remove unnecessary quotation in [[ .. ]] construct as per ulm's feedback

 * add debug-print-function to all functions (just seems like a potentially
   useful addition)

 * remove blank line between function docs and declaration

Does not appear to need any additional EAPI 8 considerations. Add
debug-print-function lines to all functions.

 # @BLURB: Provide generic install functions so that modular texlive's texmf ebuild will only have to inherit this eclass
 # @DESCRIPTION:
 # Purpose: Provide generic install functions so that modular texlive's texmf ebuilds will
 # only have to inherit this eclass.
 # Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
 # of packages that it will install. (See below)
 #
 # For TeX Live versions prior to 2009, the ebuild was supposed to unpack the
 # texmf and texmf-dist directories to ${WORKDIR} (which is what the default
 # src_unpack does).
 # Starting from TeX Live 2009, the eclass provides a src_unpack function taking
 # care of unpacking and relocating the files that need it.
 #
 # It inherits texlive-common.  Patching is supported via the PATCHES
 # bash array.
 
 # @ECLASS_VARIABLE: TEXLIVE_MODULE_CONTENTS
 # @PRE_INHERIT
 # @REQUIRED
 # @DESCRIPTION:
 # The list of packages that will be installed. This variable will be expanded to
 # SRC_URI:
 # foo -> texlive-module-foo-${PV}.tar.xz
 
 # @ECLASS_VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
 # @PRE_INHERIT
 # @REQUIRED
 # @DESCRIPTION:
 # The list of packages that will be installed if the doc useflag is enabled.
 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
 
 # @ECLASS_VARIABLE: TEXLIVE_MODULE_SRC_CONTENTS
 # @PRE_INHERIT

 # @DESCRIPTION:
 # The list of packages that will be installed if the source useflag is enabled.
 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
 
 # @ECLASS_VARIABLE: TEXLIVE_MODULE_BINSCRIPTS
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # A space separated list of files that are in fact scripts installed in the
 # texmf tree and that we want to be available directly. They will be installed in
 # /usr/bin.
 
 # @ECLASS_VARIABLE: TEXLIVE_MODULE_BINLINKS
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # A space separated list of links to add for BINSCRIPTS.
 # The syntax is: foo:bar to create a symlink bar -> foo.
 
 # @ECLASS_VARIABLE: TL_PV
 # @INTERNAL
 # @DESCRIPTION:
 # Normally the module's PV reflects the TeXLive release it belongs to.
 # If this is not the case, TL_PV takes the version number for the
 # needed app-text/texlive-core.
 
 # @ECLASS_VARIABLE: TL_MODULE_INFORMATION

 # @BLURB: Provide generic install functions so that modular texlive's texmf ebuild will only have to inherit this eclass
 # @DESCRIPTION:
 # Purpose: Provide generic install functions so that modular texlive's texmf ebuilds will
 # only have to inherit this eclass.
 # Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
 # of packages that it will install. (See below)
 #
 # For TeX Live versions prior to 2009, the ebuild was supposed to unpack the
 # texmf and texmf-dist directories to ${WORKDIR} (which is what the default
 # src_unpack does).
 # Starting from TeX Live 2009, the eclass provides a src_unpack function taking
 # care of unpacking and relocating the files that need it.
 #
 # It inherits texlive-common.  Patching is supported via the PATCHES
 # bash array.

 # @ECLASS_VARIABLE: TEXLIVE_MODULE_CONTENTS
 # @PRE_INHERIT
 # @REQUIRED
 # @DESCRIPTION:
 # The list of packages that will be installed. This variable will be expanded to
 # SRC_URI:
 # foo -> texlive-module-foo-${PV}.tar.xz

 # @ECLASS_VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
 # @PRE_INHERIT
 # @REQUIRED
 # @DESCRIPTION:
 # The list of packages that will be installed if the doc useflag is enabled.
 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.

 # @ECLASS_VARIABLE: TEXLIVE_MODULE_SRC_CONTENTS
 # @PRE_INHERIT
 # @REQUIRED
 # @DESCRIPTION:
 # The list of packages that will be installed if the source useflag is enabled.
 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.

 # @ECLASS_VARIABLE: TEXLIVE_MODULE_BINSCRIPTS
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # A space separated list of files that are in fact scripts installed in the
 # texmf tree and that we want to be available directly. They will be installed in
 # /usr/bin.

 # @ECLASS_VARIABLE: TEXLIVE_MODULE_BINLINKS
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # A space separated list of links to add for BINSCRIPTS.
 # The syntax is: foo:bar to create a symlink bar -> foo.

 # @ECLASS_VARIABLE: TL_PV
 # @INTERNAL
 # @DESCRIPTION:
 # Normally the module's PV reflects the TeXLive release it belongs to.
 # If this is not the case, TL_PV takes the version number for the
 # needed app-text/texlive-core.

 # @ECLASS_VARIABLE: TL_MODULE_INFORMATION
 # @DEFAULT_UNSET
 # @DESCRIPTION:
 # Information to display about the package.
 # e.g. for enabling/disabling a feature
