Dear list,
I have the following sample:
\starttext
\def\numbersfname
{\cldcontext{string.match([[\env{fname}]], "\letterpercent d+")}}
\ctxlua{ c = context.getvariable("environment", "fname") or "a" }
\ctxlua{ d = [[\env{fname}]] }
tex: \numbersfname\\
\doifelse{}
{123}{yes}{no}\\
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
For compilation, I run the command:
context --purgeall --arguments=fname={abc123} test-file.tex
These things are failing:
1. I don’t know how to get \numbersfname equal to "123". I don’t know
what I’m doing wrong.
2. Is there no Lua version of \getvariable{...}{...}?
3. I’m trying this on a Linux box, but on Windows I would say that Lua
variable "d" is empty.
I need to get the number from \env{fname} and I don’t know what I’m
missing. \doif is the way to test whether it’s right.
Could anyone explain me what I’m missing here?
Many thanks,
Pablo
