escaping quotes in \ctxlua

escaping quotes in \ctxlua

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \starttext
    \startluacode
    tex.print(os.getenv("USER")
    \stopluacode

    \ctxlua{tex.print(os.getenv("USER")}
    \stoptext

How can I escape the quotes in the \ctxlua command?

Many thanks for your help,


Pablo

You have to add a  closing ) for tex.print in both Lua calls but you can 
replace the second version with \cldcontext{os.getenv("USER")}.

Hello Pablo,
print commands are not balanced, second right parenthesis is missing.
Then it will work.

Many thanks for your replies, Wolfgang and Thomas.

I knew that parentheses need to be closed, but I totally overlooked it
in both tex.print commands.

Many thanks for your help and sorry for the noise,


Pablo
