-- filename : luat-inp.lua
-- comment : companion to luat-lib.tex
-- author : Hans Hagen, PRAGMA-ADE, Hasselt NL
-- copyright: PRAGMA ADE / ConTeXt Development Team
-- license : see context related readme files
-- This lib is multi-purpose and can be loaded again later on so that
-- additional functionality becomes available. We will split this
-- module in components when we're done with prototyping.
-- TODO: os.getenv -> os.env[]
-- TODO: instances.[hashes,cnffiles,configurations,522] -> ipairs (alles check, sneller)
-- TODO: check escaping in find etc, too much, too slow
-- This is the first code I wrote for LuaTeX, so it needs some cleanup.
-- To be considered: hash key lowercase, first entry in table filename
-- (any case), rest paths (so no need for optimization). Or maybe a
-- separate table that matches lowercase names to mixed case when
-- present. In that case the lower() cases can go away. I will do that
-- only when we run into problems with names ... well ... Iwona-Regular.
-- Beware, loading and saving is overloaded in luat-tmp!
