Hi,
the following example compiles fine with LuaTeX, but LuajitTeX fails to find the font.
\setupalign[r2l] \definefont[Sheherazade][name:scheherazade*arabic at 18pt] \starttext \Sheherazade أهلا بالعالم! \stoptext
fonts > defining > font with asked name 'scheherazade' is not found using lookup 'name' fonts > defining > unknown font 'scheherazade', loading aborted fonts > defining > unable to define 'scheherazade' as 'Sheherazade--0'
The font is in the font database and regular LuaTeX succeeds.
mtxrun --script fonts --list -all scheh
scheherazade scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf scheherazadenormal scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf
This might be related to the thread from a few days ago:

PS: The font can be found here:
thanks for the report. Currently I'm not able to investigate these issues, I will take them on the first week of September.

I occasionaly have similar troubles with math fonts (font works with luatex but not with luatexjit or vice versa), but a mtxrun --script fonts --reload --force fixes that. Aditya

Hard to say what is the issue but it is not a luajittex issue. We don't do anything special, for instance jit is turned off because there is no gain at all (actually with jit enabled, the run is slower). So we only use the luajit virtual machine (in mkiv). There is however one difference and that is the compiled lua code: lua and luajit have incompatible formats (apart from the fact that luatex is 5.2 and luajittex is 5.1++). Normally compilation happens automatically i.e. when a font is loaded by luatex, context will generate the relevant compiled file when luajittex is used. One possibility is that there is some mismatch in version numbers that gets unnoticed. In such case, as Aditya suggests, wiping the cache is an option.

I can confirm that. I did not find a real-world document which compiled faster with jit. Using the virtual machine provides between 8% and 25% speed gain here.

Let me know if I can provide any additional info.

That helped, indeed. Marco

there is a bit more to gain otherwise (luigi and i will talk about speed related issues at the context meeting)

ok, but currently i have no clue (it might be that there has been a fix without jumping the internal otf handler version number, in which case a mismatch can go unnoticed and no recompile happens in the jit variant) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
