Hi all,
how do I trigger another pass?
Using md5 and io I want to save data to a helper file and reuse it in a second pass (like e.g. mtx-context.lua) or update the file if appropriate. But I couldn't quite figure out how to request another pass from the lua end.
there's
jobfiles.run( "filename-to-be-checked", "command-to-be-executed-if-changed" )
Good evening, Hans!
Let me clarify my intention a bit: jobfiles.run calls "context" on the argument list, but that is not what I need.
My problem is that I generate stuff during the tex run and want to collect it in a table that is saved to a file at the end of the run. This data is hashed at the beginning of the document and if the hash does not match the end-run hash _or_ the file doesn't exist in the first place, then I'd like to run another independent pass.
(I guess I could use jobfiles.run to process \jobname at the very end of the document but would have to handle recursion somehow.)
so, as you save your data in a file, just after saving the table, hash that file: \starttext test \startluacode jobvariables.tobesaved.MyPersonalChecksum = file.checksum("MyName") or "no checksum" \stopluacode \stoptext the context runner will take care of extra runs then. (I'll think about a more robust user space for such status variables but as long as you use UpperCased names you quite safe.) ----------------------------------------------------------------- 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 -----------------------------------------------------------------
