Hello,
I have some code like this:
---------------------------------
\def\MakeSomething{... some code that returns number 12}
\startluacode
function WorkWithSomething(data)
-- call MakeSomething to obtain 12
-- base on the value above make some decisions
end
WorkWithSomething(some_data)
\stopluacode
---------------------------------
If I use context.MakeSomething() inside the lua block, this is
buffered till the end of the block, so I can't get the result and work with
it.
If MakeSomething is a command already "edef-ed", I can use
tokens.getters.macro.MakeSomething to find the value.
If MakeSomething has an argument which is determined within the
lua block, then I can't use this hack.
The ugly partial solution I have found is to change the signature of
WorkWithSomething to receive an argument and then I replicate the
parameters of MakeSomething on the TeX side:
---------------------------------
\def\MakeSomething#1{...}
\startluacode
function WorkWithSomething(data,MakeSomethingOutput)
-- we wanted to use some computation on data to obtain input to
MakeSomething
-- then call MakeSomething to obtain its result
end
\stopluacode
\ctxlua{WorkWithSomething(some_data, "\MakeSomething{replicate processing
on data to obtain input to this macro}")}
---------------------------------
Is there a more elegant solution?
Ideally I want a way to start a TeX process under Lua, and
process the macros there before I get to the next line of Lua code.
In my motivation, MakeSomething is \datasetvariable. I wanted to look up
something in the dataset and use it for the rest of computation/typesetting.
Thanks a lot,
--Mohammad
