10 # @BLURB: Provide generic install functions so that modular texlive's texmf ebuild will only have to inherit this eclass
11 # @DESCRIPTION:
12 # Purpose: Provide generic install functions so that modular texlive's texmf ebuilds will
13 # only have to inherit this eclass.
14 # Ebuilds have to provide TEXLIVE_MODULE_CONTENTS variable that contains the list
15 # of packages that it will install. (See below)
16 #
17 # For TeX Live versions prior to 2009, the ebuild was supposed to unpack the
18 # texmf and texmf-dist directories to ${WORKDIR} (which is what the default
19 # src_unpack does).
20 # Starting from TeX Live 2009, the eclass provides a src_unpack function taking
21 # care of unpacking and relocating the files that need it.
22 #
23 # It inherits texlive-common. Patching is supported via the PATCHES
24 # bash array.
25
26 # @ECLASS-VARIABLE: TEXLIVE_MODULE_CONTENTS
27 # @DESCRIPTION:
28 # The list of packages that will be installed. This variable will be expanded to
29 # SRC_URI:
30 # foo -> texlive-module-foo-${PV}.tar.xz
31
32 # @ECLASS-VARIABLE: TEXLIVE_MODULE_DOC_CONTENTS
33 # @DESCRIPTION:
34 # The list of packages that will be installed if the doc useflag is enabled.
35 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
36
37 # @ECLASS-VARIABLE: TEXLIVE_MODULE_SRC_CONTENTS
38 # @DESCRIPTION:
39 # The list of packages that will be installed if the source useflag is enabled.
40 # Expansion to SRC_URI is the same as for TEXLIVE_MODULE_CONTENTS.
41
42 # @ECLASS-VARIABLE: TEXLIVE_MODULE_BINSCRIPTS
43 # @DESCRIPTION:
44 # A space separated list of files that are in fact scripts installed in the
45 # texmf tree and that we want to be available directly. They will be installed in
46 # /usr/bin.
47
48 # @ECLASS-VARIABLE: TEXLIVE_MODULE_BINLINKS
49 # @DESCRIPTION:
50 # A space separated list of links to add for BINSCRIPTS.
51 # The systax is: foo:bar to create a symlink bar -> foo.
52
53 # @ECLASS-VARIABLE: TL_PV
54 # @DESCRIPTION:
55 # Normally the module's PV reflects the TeXLive release it belongs to.
56 # If this is not the case, TL_PV takes the version number for the
57 # needed app-text/texlive-core.
58
59 # @ECLASS-VARIABLE: TL_MODULE_INFORMATION
60 # @DESCRIPTION:
61 # Information to display about the package.
62 # e.g. for enabling/disabling a feature
63
64 # @ECLASS-VARIABLE: PATCHES
65 # @DESCRIPTION:
66 # Array variable specifying any patches to be applied.
