Hello *, |
| 2 |
|
| 3 |
Some time ago, some Gentoo TeX guru (don't remember who) advised to |
| 4 |
include the following code to the sci-mathematics/maxima ebuild: |
| 5 |
|
| 6 |
# Calculating MAXIMA_TEXMFDIR |
| 7 |
if use latex; then |
| 8 |
local TEXMFPATH="$(kpsewhich -var-value=TEXMFSITE)" |
| 9 |
local TEXMFCONFIGFILE="$(kpsewhich texmf.cnf)" |
| 10 |
|
| 11 |
if [ -z "${TEXMFPATH}" ]; then |
| 12 |
eerror "You haven't defined the TEXMFSITE variable in your TeX config." |
| 13 |
eerror "Please do so in the file ${TEXMFCONFIGFILE:-/var/lib/texmf/web2c/texmf.cnf}" |
| 14 |
die "Define TEXMFSITE in TeX configuration!" |
| 15 |
else |
| 16 |
# go through the colon separated list of directories |
| 17 |
# (maybe only one) provided in the variable |
| 18 |
# TEXMFPATH (generated from TEXMFSITE from TeX's config) |
| 19 |
# and choose only the first entry. |
| 20 |
# All entries are separated by colons, even when defined |
| 21 |
# with semi-colons, kpsewhich changes |
| 22 |
# the output to a generic format, so IFS has to be redefined. |
| 23 |
local IFS="${IFS}:" |
| 24 |
|
| 25 |
for strippedpath in ${TEXMFPATH}; do |
| 26 |
if [ -d ${strippedpath} ]; then |
| 27 |
MAXIMA_TEXMFDIR="${strippedpath}" |
| 28 |
break |
| 29 |
fi |
| 30 |
done |
| 31 |
|
| 32 |
# verify if an existing path was chosen to prevent from |
| 33 |
# installing into the wrong directory |
| 34 |
if [ -z ${MAXIMA_TEXMFDIR} ]; then |
| 35 |
eerror "TEXMFSITE does not contain any existing directory." |
| 36 |
eerror "Please define an existing directory in your TeX config file" |
| 37 |
eerror "${TEXMFCONFIGFILE:-/var/lib/texmf/web2c/texmf.cnf} or create at least one of the there specified directories" |
| 38 |
die "TEXMFSITE variable did not contain an existing directory" |
| 39 |
fi |
| 40 |
fi |
| 41 |
fi |
| 42 |
|
| 43 |
It is absolutely clear, and should work for arbitrarily configured TeX. |
| 44 |
Later, I copied it (practically verbatim) to the media-gfx/asymptote |
| 45 |
ebuild. |
| 46 |
|
| 47 |
With the default Gentoo configuration of either teTeX or TeXlive, this |
| 48 |
code always produces |
| 49 |
|
| 50 |
/usr/share/texmf-site |
| 51 |
|
| 52 |
There are a lot of packages which have this path hard-coded: |
| 53 |
|
| 54 |
app-emacs/auctex |
| 55 |
app-emacs/bbdb |
| 56 |
app-text/passivetex |
| 57 |
app-text/xetex |
| 58 |
dev-tex/culmus-latex |
| 59 |
dev-tex/currvita |
| 60 |
dev-tex/dot2texi |
| 61 |
dev-tex/envlab |
| 62 |
dev-tex/europecv |
| 63 |
dev-tex/feynmf |
| 64 |
dev-tex/g-brief |
| 65 |
dev-tex/glossaries |
| 66 |
dev-tex/herm-pic |
| 67 |
dev-tex/latex2html |
| 68 |
dev-tex/latex-beamer |
| 69 |
dev-tex/leaflet |
| 70 |
dev-tex/listings |
| 71 |
dev-tex/mh |
| 72 |
dev-tex/oesch |
| 73 |
dev-tex/pgf |
| 74 |
dev-tex/svninfo |
| 75 |
dev-tex/texmfind |
| 76 |
dev-tex/translator |
| 77 |
dev-tex/xcolor |
| 78 |
dev-tex/xkeyval |
| 79 |
dev-tex/xmltex |
| 80 |
sci-visualization/gnuplot |
| 81 |
|
| 82 |
So, probably, this code is an unneeded over-generalization, and should be |
| 83 |
simply replaced by the hard-coded /usr/share/texmf-site in both maxima and |
| 84 |
asymptote. Alternatively, if anybody thinks that this generalization can |
| 85 |
be useful (in what case?), we could include this code as a function into |
| 86 |
latex-package.eclass, and fix all the ebuilds listed above to use it. The |
| 87 |
current inconsistent situation is not good. |
| 88 |
|
| 89 |
I think the first solution is simpler (and I can do it myself). But if |
| 90 |
somebody thinks this generalization to the case of an arbitrary TEXMFSITE |
| 91 |
in TEXMFCONFIGFILE is useful, then let's do it properly. |
