Re: [Dev-luatex] reimplementing various scripts in texlua

Hi Lua Gurus,

we are planning to reimplement various scripts which are at the core of TeX Live (and many other TeX distributions) in texlua. I guess all of you know what we are talking about: mktexlsr, updmap, fmtutil, mktexupd, mktexnam, ...

As a finger exercise in lua programming I started implementing mktexupd. Ok, it is not perfect, but AFAIS it does the same as the shell scripts.

For something going through a directory tree, the coroutine-based approach I contributed to URL:http://lua-users.org/wiki/DirTreeIterator might be worth looking at. It's quite to the point and shows the power of coroutines in Lua (basically somewhat related to programming with bidirectional pipes). -- David Kastrup
