Dear list,
is there a way if a program is installed on the computer using Lua.
I have the following sample:
\starttext \startluacode filename = tex.jobname .. ".pdf" os.exec("dir " .. filename) \stopluacode \stoptext
Is there a way to wrap os.exec() in the sample so that it only runs if "dir" is available?
I know that os.name would be an option here, but not in my real world document.
\starttext \startluacode if lfs.isfile(tex.jobname .. ".pdf") then context("YES") end if lfs.isfile(file.addsuffix(environment.outputfilename,"pdf")) then context("YES") end if #dir.glob(file.addsuffix(environment.outputfilename,"pdf")) > 0 then context("YES") end \stopluacode \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
