--luatex option failing

--luatex option failing

[jbf]

Hi list,

Not at all sure why this is happening. In my most recent install of lmtx 
(which works fine as lmtx) on Linux, I wanted to choose the --luatex 
option just to make a comparison between the mkiv output and lmtx.

The redirection part seems to work (... --script mtx-context --luatex 
myfile.tex --redirected), but no 'resolvers' follow. Instead I get 
mtxrun  | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'.

I have tried both luatextools --generate and mtxrun --generate, but 
neither of these fix the problem. Would someone know why this is not 
working? Or even better, how to fix it? I installed lmtx on another 
machine and have no problems using the --luatex option there, so the 
matter is not urgent for me, just puzzling! I do have a separate mkiv 
installation as well, but my understanding is that they would not 
conflict. LMTX contains everything that is needed.

In lmtx "mtxrun" and "context" are just links to "luametatex" and when 
called with a different name than "luametatex" they will try to locate 
scripts with their name in the same path (so there need to be mtxrun.lua 
and context.lua in that nin path). The mtxrun.lua file contains most lua 
libs so it can provide the same helpers as in context, when used as 
stand alone runner (so, instead if native lua one can just use mtxrun) 
while the context.lua script will locate mtx-context.lua and run that 
one. For that it needs the file database.

Forget about luatools .. gone for ages. An mtxrun --generate or even 
context --generate should work ok. if not there's somethign with 
permissions or paths or a missing file.

Still finding it very difficult to nail what the real problem is. You 
say: "An mtxrun --generate or even context --generate should work ok. if 
not there's something with permissions or paths or a missing file".

Neither of the --generate options make any difference, so it clearly has 
to come down to "permissions or paths or a missing file". I cannot see 
that it is permissions. Comparing permissions on both machines (one 
working with --luatex and one not) I cannot see any difference. Paths? 
The only thing I can see is that I also have (later in the path) a 
separate installation for mkiv... but surely that would not make a 
difference? So, a missing file??

I renamed the current folder called lmtx so it would not be recognised 
(called it lmtxx) and created a new lmtx folder into which I have 
installed a new version (and obviously it would still be in the path, 
since ~/Documents/lmtx/tex/texmf-linux-64/bin is already in the path).

So two questions: (1) Is it possible that having another version (mkiv) 
later in the path is causing the problem? (2) If a file is missing, what 
could it possibly be, given that I did a fresh install?

As this may be an 'ignorant' kind of question, something I should really 
know but don't, about paths and permissions, there may be someone else 
on the list with time (in lockdown like I am) to put me right.

not really, because the location where the running bin is found is 
determining the root of the to be used tds .. (i assume your cache is in 
that tree, not in some /tmp although even then the hashed name should 
prevent clashes)

you need help from a linux expert indeed

Just a comment. I also experienced problems in Linux with --luatex some
days ago.

I got everything right with current latest (2021.05.27 14:15).

I would erase the cache and try it again:

  mtxrun --script cache --erase && mtxrun --generate

I’m not a Linux expert at all. But this might help.
