Contributing to Babel or Polyglossia language support

Question

I want to contribute language support for Babel or Polyglossia, so that I can type in my native language and use LuaTex or LuaLaTeX. Lithuanian support at the moment is using L7x font encoding and if I try to use it as it is, it gives me an error.

! LaTeX Error: Encoding scheme `L7x' unknown.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

This is the minimal working example (compile with lualatex):

\documentclass{scrartcl}

\usepackage{fontspec,luatextra}
\usepackage[lithuanian]{babel}

\begin{document}
Hello world ąžerty
\end{document}

So, I want to contribute to the babel Lithuanian language support by porting the required parts for LuaLaTeX, but do not have the know how yet.

Question: What should I be aware before I start and where should I start? Or would it be easier to start playing with Polyglossia? What is its status on LuaTeX right now?

P.S I am aware of the new babel maintainer but under his provided link there is no Lithuanian language directory. However, there is a CTAN entry, but I have no idea about it's structure.

Answer 1

There is a mailing list for TeX and hyphenation patterns. This is a good starting point for anything TeX-and-language-related.

For babel you could file a bug report with the LaTeX project.

For polyglossia you could also file an issue with the current maintainer.
