Command/ctxlua

Summary

The command \ctxlua is used to execute Lua code.

Settings

\ctxlua{...}
{...}	command

Description

Use this command to quickly execute some Lua code. TeX expands the argument before Lua receives it.

Advantage: you can pass the contents of macro parameters like #1 to Lua.

Disadvantage: everything after a percent sign is ignored, and once the comments are processed out the linebreaks are stripped, too.

Examples

Example 1

\ctxlua{context(1+5)} % 6

%\ctxlua{context("5%")}  % Is seen as `\ctxlua{context("5`

% 1, 2, 4, 8
\ctxlua{
    context(1)  % this comment is okay
    i=2;
    while i < 10 do
       context(', ' .. i);
       i = i*2
    end}
