file name resolving for lua files

file name resolving for lua files

[Aditya Mahajan]

Hi,

I have noticed that my local context update scripts were not always 
working correctly. In particular, the mtxrun and luatools file never got 
updated. The reason is the following.

When I run mtxrun --selfupdate I get

     mtxrun --selfupdate
     MTXrun | fileio: to be replaced old script
     /opt/experimental/tex/texmf-linux-64/bin/mtxrun
     MTXrun | fileio: using suffix based filetype 'texmfscripts'
     MTXrun | fileio: checking new script
     /opt/experimental/tex/texmf-context/scripts/context/stubs/mswin/mtxrun.lua
     MTXrun | fileio: new script should come from scripts/context/lua

So, mtxrun is trying to replace mtxrun from the stubs directory. In fact, 
if I get the same result from

     luatools --locate mtxrun.lua
     /opt/experimental/tex/texmf-context/scripts/context/stubs/mswin/mtxrun.lua

Something is wrong with the search logic as texmfstart also gets this 
wrong.

     texmfstart --locate mtxrun.lua
     /opt/experimental/tex/texmf-context/scripts/context/stubs/mswin/mtxrun.lua%

However, kpsewhich works correctly.

     kpsewhich mtxrun.lua
     /opt/experimental/tex/texmf-context/scripts/context/lua/mtxrun.lua

Do others also get the same result? Any idea what is going wrong here?

Aditya

Hi Aditya,

On my machine (Mac OS X) the Minimals are installed and when trying what you suggest I get the correct path:

localhost:~ kavian$ luatools --locate mtxrun.lua
/context-minimal/tex/texmf-context/scripts/context/lua/mtxrun.lua

localhost:~ kavian$ texmfstart --locate mtxrun.lua
/context-minimal/tex/texmf-context/scripts/context/lua/mtxrun.lua
localhost:~ kavian$ 

I remember that a long time ago when I was using texlive, at some point the issues with scripts being in a "stubs" subdirectory of context appeared, but don't remember how the issue was fixed (maybe Mojca or Hans did something magic to solve it?).

Best regards: OK

Can anyone on linux 64 confirm this? I want to cofirm if this is something 
general or specific to my machine.

I get the correct result with TL09, but incorrect result on two differnt 
minimal installations.

can you run with 
--track=resolvers.locating,resolvers.details,resolvers.expansions

(or --resolvers=*)

The output of

  luatools  --track=resolvers.locating,resolvers.details,resolvers.expansions --find-file mtxrun.lua

is attached. I don't know know to interpret the result, but nothing seems 
glaringly wrong.

need some thinking ...

anyhow, i get

LuaTools | fileio: checking filename 'mtxrun.lua'
LuaTools | fileio: file './mtxrun.lua' is not readable
LuaTools | fileio: file 'c:/data/develop/context/lua/mtxrun.lua' is readable
LuaTools | fileio: found 'c:/data/develop/context/lua/mtxrun.lua' by 
scanning
LuaTools | fileio: c:/data/develop/context/lua/mtxrun.lua

btw ... we can remove the etex, pdfetex and omega entries in the cnf 
file i think (i wonder if there's anything useful in those subpaths)

normally stubs come after lua but maybe not on your machine

so, we might better use this:

$TEXMF/scripts/context/{lua,ruby,perl}//

(i cc mojca for the minimals and taco for tex live)

normally this is not that important as there is only one instance ..

also, selfupdate should not be influenced by that as it should take the 
original

Thanks. I changed TEXMFSCRIPTS in texmf.cnf to include the specific 
directories, and now luatools finds the correct file and --selfupdate 
works.

Do you mean that the stubs director should not have mtxrun.lua? I have

$find /opt/experimental -name 'mtxrun.lua'
/opt/experimental/tex/texmf-context/scripts/context/stubs/mswin/mtxrun.lua
/opt/experimental/tex/texmf-context/scripts/context/lua/mtxrun.lua

Re: file name resolving for lua files

[Aditya Mahajan]

Also, mtxrun and luatools do not set the exit flag correctly in case of 
a failure. For example, (in the old setup)

$mtxrun --selfupdate 
MTXrun | fileio: to be replaced old script /opt/context-minimals/texmf-linux-64/bin/mtxrun
MTXrun | fileio: using suffix based filetype 'texmfscripts'
MTXrun | fileio: checking new script /opt/context-minimals/texmf-context/scripts/context/stubs/mswin/mtxrun.lua
MTXrun | fileio: new script should come from scripts/context/lua

$ echo $?
0

Because of this, I never noticed that something was going wrong in my 
update scripts.

eh ... there is no stub on your machine, just mtxrun (without suffix) 
copied to bin, on windows there is mtxrun.exe and mtxrun.lua in the bin 
path

i just put duplicates into mswin/stubs for convenience
