Only a question. When Luigi announced luajittex-0.78.2
(http://www.ntg.nl/pipermail/ntg-context/2014/076633.html), he commented
the possibility of having only luajittex in the future.
What happened to that merging?
You probably misunderstood the message. Luigi kept developing
LuaJITTeX separately from LuaTeX until recently, at
https://foundry.supelec.fr/projects/luajittex, so the two projects
(luatex and luajittex) contained almost the same source code with only
minor differences and we had to compile them separately. Both projects
now coexist at https://foundry.supelec.fr/projects/luatex in the same
subversion repository and both binaries are built from the same
sources.
Concerning 'only luajittex' .. it will always be two separate binaries
- luajit is only available for some architectures
- luajittex has some memory constraints due to the different Lua vm
In context you use
mtxrunjit ...
contextjit ...
if you want the most efficient call, although (at least for now)
mtxrun --jit
context --jit
will also work (but starts up slower due to a relaunch, using some ugly
hacks).
On the average luajittex runs faster (some 15-20% normally, but it can
be less or more depending on how extreme Lua usage is).
