Pass a tex value to lua in context

Question

I have the following code

\startluacode
company = context.env("company")
patch_file = "public/" .. company .. "/patch-english.json"
\stopluacode

where I pass the company value via command line context --arguments=company=mycompany mydoc.tex

This does obviously not work. How can I get the variable from the command line into lua code?

Answer 1

You can use environment.argument to query the command line arguments.

\starttext

\startluacode
company = environment.argument("company")
context("company = " .. company)
\stopluacode

\stoptext

context --company=mycompany test.tex

If you do not want to use Lua, you can try

\starttext

company = \env{company}

\stoptext

context --arguments=company=mycompany test.tex
