And can I check a variable (argument) in Lua in a similar way?
---
\starttext
Print mode: \doifmodeelse{print}{yes}{no}
\startluacode
if tex.modes['print'] then
context("Print mode is enabled")
else
context("Print mode is disabled")
end
-- Something like this: >>
if tex.arguments['size'] == "small" then
-- Or: 'tex.variables["size"] == "small"'
-- Or: 'document.arguments["size"] == "small"'
context("Small size")
end
--
\stopluacode
\doifenvelse{size}
{\processaction
[\env{size}]
[ small=>Small size,
medium=>Medium size,
big=>Big size,
unknown=>Other size: \env{size}]}
{No value “size”}
\stoptext

If the passed argument has a NUMBER value, should it be checked against a number value or a string - so what of the following should be right:
context --arguments="size=1" test.tex
if tex.arguments['size'] == "1" then ...
Or:
if tex.arguments['size'] == 1 then ...
Best regards,
Lukas
