Hi,
please have a look at the following example:
\starttext
\def\cmd{%
\def\mymacro{Foobar}
\newtoks\mytoks
\mytoks={mytoks}}
\startluacode
context.cmd()
context.mymacro()
-- this fails
-- context(tex.toks.mytoks)
\stopluacode
-- this works
\startluacode
context(tex.toks.mytoks)
\stopluacode
\stoptext
Why does the first call to tex.toks.mytoks fail?
Apparently the luacode environment has to be closed for cmd to be
expanded. I guess that the call to mymacro() succeeds is a quirk due
to the face that the macro is expanded later, in contrast to tokens,
dimens and counters.
Is there a command I can use within Lua to expand a macro
immediately or to expand the pending macros to be able to access the
values like the token register in the example?
Another question which is related:
Is there a way to access the contents of the macro from within Lua
like counters and token registers?
\starttext
\newtoks\mytoks
\mytoks={Foobar}
\startluacode
local tok = tex.toks.mytoks
-- something like this is what I have in mind
-- local mac = tex.macros.somemacro
\stopluacode
\stoptext
I am just interested in a text string, not a box with typeset
material. I guess that's more difficult, since macros are expanded
and not just simply read.
Marco
