[Therion] th_formdef.tex runaway text error - LuaTeX

Tue Sep 1 22:11:34 CEST 2026

Thanks Martin

I’ll need some more hand holding.

I can find https://github.com/lualatex which gives many variations that I cannot make sense of, and https://gitlab.lisn.upsaclay.fr/texlive/luatex which looks like it has a definitive install, but it is not github.

Is it one of these?

Hi Bruce,

you need

- a recent development snapshot from github

- to specify the full path to luatex.exe, like pdftex-path "C:/Program files/Therion/bin/windows/luatex.exe"

I’ve edited C:\Program Files\Therion\therion.ini to include… pdftex-path  "luatex"

I’m missing something:

Running my thconfig with Mapiah, I get a log file that ends with…

making map ... done

'luatex' is not recognized as an internal or external command, operable program or batch file.

C:\Program Files\Therion\therion.exe: error --Press ENTER to exit! pdftex exit code – 1

Running my thconfig with XTherion, there is no mention of Luatex.  I get a log file that ends with…

##################### end of pdftex log file #####################

C:\Program Files\Therion\therion.exe: error -- pdftex exit code -- 1

writing xtherion file ... done

I checked my %APPDATA%\ folders, and the only Therion related ini in there is Loch.ini

Any ideas?

Bruce
