Prioritise TEXMFHOME

Prioritise TEXMFHOME

[Marco Patzer]

[-- Attachment #1.1: Type: text/plain, Size: 196 bytes --]

Hi,

can I somehow set up that files within TEXMFHOME are preferred to
files found in the distribution? Or is there another variable which
is more suitable than TEXMFHOME for this purpose?

Doesn't it already have the highest priority?

MkII:

TEXMFHOME     = $HOME/texmf
TEXMF         =
{$TEXMFHOME,!!$TEXMFPROJECT,!!$TEXMFFONTS,!!$TEXMFLOCAL,!!$TEXMFMODULES,!!$TEXMFCONTEXT,!!$TEXMFOS,!!$TEXMFMAIN}

MkIV:

TEXMFHOME       = "home:texmf",
TEXMF           =
"{$TEXMFHOME,!!$TEXMFPROJECT,!!$TEXMFFONTS,!!$TEXMFLOCAL,!!$TEXMFMODULES,!!$TEXMFCONTEXT,!!$TEXMFSYSTEM,!!$TEXMFMAIN}",

I did assume that, but that's not the case. Take your t-gnuplot.tex
module, for instance, make some changes and place it in $TEXMFHOME.
ConTeXt still uses the old version found in

texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex

I don't know how to reproduce that even though I remember that I had
problem if I set "export TEXMFHOME=/path/with/trailing/slash/".

What does
    mtxrun t-gnuplot.tex
return you?

Also:
- What is your $TEXMFHOME and how did you change it in case that you did?
- Where exactly is your file t-gnuplot.tex?
- Do you run MkIV? With current beta or with TeX Live?
- What does 'kpsewhich t-gnuplot.tex' return you?

I used the following setup to create a reproducible clean
environment without interference of possibly set variables.

curl -O http://minimals.contextgarden.net/setup/first-setup.sh
chmod +x first-setup.sh
./first-setup.sh --modules=t-gnuplot
mkdir mymodules
echo '\bold' >mymodules/t-mymodule.tex
echo '\sans' >mymodules/t-gnuplot.tex
cat > test-mymodule.tex <<EOF
\usemodule [mymodule]
\starttext
\input knuth
\stoptext
EOF
cat > test-mygnuplot.tex <<EOF
\usemodule [gnuplot]
\starttext
\input knuth
\stoptext
EOF
source tex/setuptex
export TEXMFHOME=mymodules
context test-mymodule.tex test-mygnuplot.tex

mymodule is loaded and the text is printed in bold, the modified
gnuplot module is not loaded.

test setup:
/home/fusion/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex
mymodules/t-gnuplot.tex

in my real setup only the distribution file is found. I didn't yet
try to figure out why.

> - What is your $TEXMFHOME and how did you change it in case that you did?

See minimal example above. In my real setup it's

  /home/marco/usr/share/texmf

and it's set in $HOME/.profile using export TEXMFHOME=…

> - Where exactly is your file t-gnuplot.tex?

See minimal example above. In my real setup it's

  /home/marco/usr/share/texmf/t-gnuplot.tex

> - Do you run MkIV?

Yes

> With current beta or with TeX Live?

current version: 2013.01.22 18:33

> - What does 'kpsewhich t-gnuplot.tex' return you?

I didn't know ConTeXt uses kpsewhich.

test setup:
/home/fusion/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex

real setup:
/home/marco/usr/local/share/context-beta/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex

You should put the file under
   mymodules/tex/context/third/t-gnuplot.tex
and not just anywhere on top level of $TEXMFHOME.

At least somewhere under mymodules/tex/ (but I'm not sure if that
alone is 100% safe - that is - I'm not sure about the search/sort
order of two files with the same name under a different path inside
the texmf tree).

In MkII it does. But I meant it more like a cross-check. It might be
that there would be some bug in mtxrun when searching for files and in
that case kpsewhich may serve as a confirmation that your set up works
or doesn't work properly.

That works, thanks. I didn't think about the importance of the tex
file system structure within TEXMFHOME since my personal files
always have been picked up from random subdirectories within
TEXMFHOME.

mymodules/tex doesn't seem to be sufficient. My tests revealed that
for files not present in the distribution tex tree the location
within TEXMFHOME does not matter. Files present in the distribution
which are supposed to be overwritten in TEXMFHOME need the same
path. Maybe this is more strict than necessary, but it works. A
version mismatch that gets unnoticed can be very frustrating.

All right. Problem solved. Thanks Mojca!
