Hello,
how to determine the current language being used in Ctx source via Lua? I mean
soumething like:
---
\mainlanguage[cz]
\starttext
AAA
\startluacode
if context.mainlanguage == "cz" then -- Do something specific
context("Ahoj!")
elseif context.mainlanguage == "en" then -- Do something specific
context("Hello!")
else
end
\stopluacode
\stoptext
---
So is there something like 'context.mainlanguage' or 'context.mainlanguage()'
or 'tex.mainlanguage' or ...?
\mainlanguage[...] -> \currentmainlanguage
\language[...] -> \currentlanguage
For the benefit of the mailing list archive, this means you
can write in lua:
if "\currentmainlanguage"=="cz" then
Except that that will not work because 'cz' is just an alias for 'cs',
so you should test for that instead:
if "\currentmainlanguage"=="cs" then
context("Ahoj!")
elseif "\currentmainlanguage"=="en" then
context("Hello!")
Best wishes,
Taco
- In standalone Lua, the "\c" would be read (translated) as "c", as "\c" is not
a valid escape sequence. See the test:

a="\currentmainlanguage"
=a
currentmainlanguage
=("\currentmainlanguage"=="currentmainlanguage")
true -- SO "\c" BECOMES "c"

So does it mean that "\<char>" (in the beginning of a string) in Lua for ConTeXt is a
"hack" which expands a (Con)TeX(t) internal value (in the case that <char> is not a valid
escape char)?
- If so, how to get an internal (Con)TeX(t) value which begins with a valid escape <char>, e.g. 't', so
e.g. "\textwidth"? ("\t" should become <tab> in this case, or am I wrong?)
(Where to read about? I've been searching in luatexref-t.pdf...)
