Hi Hans,
TeX Live contains ~31 times as many files as the ConTeXt distribution, so running "mtxrun --generate" is relatively slow. However, TeX Live already generates a filename index for all its files, so if we use that instead of traversing the filesystem, "mtxrun --generate" runs quite a bit quicker. My testing shows that currently "mtxrun --generate" takes 2.7 seconds to run, and with this patch it takes 1.5 seconds; real-world results will likely show an even greater difference since I tested it with repeated runs (so the OS has cached everything) and I have really fast disks.
I've included a diff inline below, and I've also attached the modified files. I didn't attach mtxrun.lua since the file is so large, so you'll need to manually copy the changes from the diff.
I don't see the advantage of adding more code just for this purpose and even hard coding 'texlive' checks. On a tex live install that takes ages itself one 1 seconds doesn't save much. I've actually been thinking of filtering: only add files to the database that matter for context which leaves out complete subtrees. The file database isn't generated that often, it's access during a run that matters more.
Also, can you please rename m-texlive.mkxl to m-texlive.mkiv? LuaTeX doesn't find the file with the ".mkxl" suffix, and I'd like to keep supporting MkIV in TeX Live.
hm, i'll make a copy then (i tend to keep mkiv and mkxl separate as they can differ eventually, in fact there are still .lua files that will go .lmt because eventually mkiv will be like mkii: frozen) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
