Max & Hans:

I installed the stand-alone ConTeXt installation just today. It seems like I have my $PATH set correctly now.

I have been editing ConTeXt and running it within TeXstudio. I had set up a "user command" to execute arara on LaTeX and ConTeXt files when I did NOT have the "standalone" version installed. It still works correctly.

Today, I created a separate "user command" within TeXstudio, and it points to "/usr/local/ConTeXt_Standalone/context-linux-64/bin/mtxrun"  This command generates the same log output as the example at https://gitlab.com/islandoftex/images/texlive/-/issues/30.

If I understand this correctly, my OLD user command within TeXstudio is still finding the TeXlive version of ConTeXt, and that TeXlive version does have the symlinks mentioned by Max (and BTW, I did NOT create those, they are part of the default TeXlive installation process!). This is because my OLD "arara" command has the path to the March 13 version of TeXlive 2023 version (installed from ISO image, with some updates using tlmgr already installed).

Hi Hans,

With the LuaMetaTeX-based ConTeXt wrapper, it's not generally possible
to run ConTeXt from a symlinked binary in another directory. This shows
up if someone makes symlinks in "/usr/bin" so that they can avoid adding
anything to their $PATH.

If you make run a symlink to the LuaMetaTeX-based ConTeXt wrapper, it
looks for texmfcnf.lua relative to the symlink location, not the symlink
target. With the old LuaTeX/kpse-based wrapper, the script would look
for texmfcnf.lua relative to the symlink target.

I know that my description above is terrible, so here's a demo:

   $ bin=$(mtxrun --expand-var TEXMFOS | head -1)/*
   $ cd $(mktemp -d)
   $ ln -s $bin/luatex $bin/luametatex $bin/context $bin/context.lua $bin/mtxrun $bin/mtxrun.lua .
   $ ./context --nofile
   $ ./context --luatex --nofile
   
Running the above commands used to work with the old LuaTeX/kpse-based
wrapper, but it doesn't work any more. I was able to ""fix"" this by
adding the lines

   if os.selfpath then
       environment.ownbin = lfs.symlinktarget(os.selfpath .. io.fileseparator .. os.selfname)
       environment.ownpath = environment.ownbin:match("^.*" .. io.fileseparator)
   else
       environment.ownpath = kpse.new("luatex"):var_value("SELFAUTOLOC")
       environment.ownbin = environment.ownpath .. io.fileseparator .. (arg[-2] or arg[-1] or arg[0] or "luatex"):match("[^" .. io.fileseparator .. "]*$")
   end
   
to mtxrun.lua, right below the line

   package.loaded["data-ini"] = package.loaded["data-ini"] or true
   
but this is obviously not a very good fix.

There are some threads with more details at:

   https://tug.org/pipermail/tex-live/2023-March/049028.html
   https://gitlab.com/islandoftex/images/texlive/-/issues/30
   
Those links only discuss TL, but I get the same issue if I make a symlink
to the standalone ConTeXt files.

Thanks,
-- Max
