Hello,

I have also the experience that when the Lua file is placed where the LUA_PATH system variable points (or: see the documentation how exactly LUA_PATH works), than I can use the 'require' command and the Lua file will be found.

E.g.:

LUA_PATH = (...);C:\MyDir\?.lua

C:\MyDir\MyFile.lua:

print("This is MyFile.lua")

And a ctx file:

\startluacode require("MyFile") \stopluacode

- Will print "This is MyFile.lua" to the output stream when converting .tex to (e.g.) .pdf.

texmf-[local|project]/scripts/context/lua should work out ok with require, given that you also have regenerated the file database

Hi list,

I'm currently messing around with a custom lua script (a pretty printer) and I have some beginner trouble.

First: I put the file in "MyContexDir\tex\texmf\tex\context\base\".

Put them into MyContexDir\tex\texmf-local\tex\context\user\ because: - You need to use texmf-local instead of texmf, else your file might be deleted when you update the distribution. - It doesn't really matter where the file is as long as it is under [TEXMF]\tex\context, but using "user" is somehow more sensible than "base".

...

What do I have to do to let ConTeXt work with the script and to let ConTeXt know that something has changed in the script? Is "context --generate" enough (after initializing with "setuptex.bat")?

You need to use context --generate only when you add the script for the first time. After you modify it, you don't need to do anything unless you are changing ConTeXt source. If you change ConTeXt source, you need to also run "context --make" (but that would be dangerous anyway).

...

Second: How can I debug errors in my *.lua file? Just put print("debug message") in the function that is (supposed to be) called?

Yes, or tex.print (depending on how you want to debug).
