lu­a­code – Helper for ex­e­cut­ing lua code from within TeX

Ex­e­cut­ing Lua code from within TeX with di­rectlua can some­times be tricky: there is no easy way to use the per­cent char­ac­ter, count­ing back­slashes may be hard, and Lua com­ments don't work the way you ex­pect. The pack­age pro­vides the \lu­aexec com­mand and the lu­a­code(*) en­vi­ron­ments to help with these prob­lems.
