ConTeXt Minimals and TEXMFCACHE

ConTeXt Minimals and TEXMFCACHE

[Nicola]

Hi,
according to the wiki “ConTeXt minimals does not touch anything outside 
its installation folder”, but if TEXMFCACHE is not set by setuptex, 
actually many files may be written outside the ConTeXt minimals folder, 
and (as in my case) they may conflict with the files written by ConTeXt 
from TeX Live in the same cache folder.

Is there any reason why exporting TEXMFCACHE is commented out in 
setuptex?

Nicola

You can set it up in a texmfcnf.lua file in your texmf-local/web2c tree.

Anyway, it is unlike to conflict as I hash the path so one cache can 
serve many trees.

The variable TEXMFCACHE is set in
    tex/texmf/web2c/texmfcnf.lua
and that one should do the job. Under usual circumstances at least.

If that one is not being respected, something might be wrong. Do you
have any other texmfcnf.lua file somewhere else?

(Note that you are also free to rename setuptex and modify it
according to your own needs, but it makes sense to debug this first.)

Ah, I hadn't realized that! That simplifies things a lot!

Thanks,

No, I export TEXMFCACHE in my .profile, because I want the cache to be 
inside my home folder. After running setuptex, ConTeXt minimals uses 
that rather than the path specified in texmfcnf.lua. Since now I know 
that luatex-cache can be shared, for me this is perfectly fine. I just 
had to adjust the TeXShop engines (I am on Mac OS X) by explicitly 
setting TEXMFCACHE for XeTeX and MKII, besides MKIV.

So, if I get it right, the value in texmfcnf.lua is used unless 
TEXMFCACHE is set.

Oh, that's another story then.

TEXMFCACHE is not used by MKII (neither in pdfTeX nor in XeTeX).

True.

I summarized this small discussion in the wiki as I also made a systemwide 
installation (http://wiki.contextgarden.net/ConTeXt_Minimals#Cache)

Right. I have tried 

unset TEXMFCACHE
texexec hello.tex

in the command line and it just runs texexec (as expected).

But from TeXShop (using the engines for MKII and XeTeX described at 
http://wiki.contextgarden.net/ConTeXt_Minimals/Mac_Installation), for 
some reason mtxrun is run before texexec on the first compilation, which 
creates the cache in the location specified by texmfcnf.lua (unless I 
set TEXMFCACHE). And sourcing setuptex doesn't change anything. Maybe 
some other environment variable should be set in those engines?

we used to have texmfstart as script runner (all scripts are located and 
started by a runner which is faster than using some kpse locator esp 
when having nested runs as with metafun in mkii)

so, texexec used to be

   texmfstart texexec

however, nowadays mtxrun is the runner and it replaces texmfstart for 
mkii as well and in order to do this, it needs the file database and 
that one ends up in the cache so even for mkii there is a cache needed 
(when I'm in the mood I'll check the lua texutil variant in which case 
we can also kick out ruby which is currently only needed for mkii)

Sorry, my mistake. If I unset TEXMFCACHE, then mtxrun is run also from 
the command line and the behaviour is consistent with what happens from 
TeXShop - which, in turn, is consistent with what Hans explains below.

Everything is clear now. Thank you!
