Lua equivalent of \getvariable{}{}

Lua equivalent of \getvariable{}{}

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \starttext
    \ctxlua{ context.setvariable("environment", "filename", "abc123") }
    \ctxlua{ c = context.getvariable("environment", "filename") or "a" }
    \ctxlua{ d = [[\env{filename}]] }

    c: \cldcontext{c}\\
    \doifelse{\cldcontext{c:match("\letterpercent d+")}}
        {123}{yes}{no}\\
    d: \cldcontext{d}\\
    \doifelse{\cldcontext{d:match("\letterpercent d+")}}
        {123}{yes}{no}
    \stoptext

Which is the Lua equivalent of \getvariable{}{}? I get nil now.

BTW, I wonder why \setvariable prints the variable, botn in Lua and ConTeXt.

Many thanks for your help,

Pablo
