is it possible to prevent LuaTeX from generating a logfile? Is there a callback for that?

there are still a bunch of writes that have no callbacks (too interwoven) but eventually all writes will have callbacks so then you can just nil them; currently you can nil most logs and run in batchmode which will make the run faster and the log rudimentary (ok, you can pipe to null too) (btw, the current version of luatex is already much more efficient in writing to the log than previous versions, so the overhead is not that large, if you disable overfull messages, and don't write yourself it's close to nothing) 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 -----------------------------------------------------------------
