Hello, is there any command to test for write18/shell escape available in ConTeXt? In one of the LaTeX packages I saw: \newif\ifShellEscape ... \ifShellEscape \def\tmpfile{/tmp/w18-test-\the\year\the\month\the\day\the\time} \ifmiktex \immediate\write18{rem >"\tmpfile"} \else \immediate\write18{touch \tmpfile} \fi \ifmiktex \IfFileExists{\tmpfile.}{\ShellEscapetrue}{\ShellEscapefalse} \else \IfFileExists{\tmpfile}{\ShellEscapetrue}{\ShellEscapefalse} \fi \fi Thanks a lot, Mojca

\ifeof18 checks if write18 is disabled. I think that it is etex only. The next method is error prone, for a lot of reasons, the directory /tmp may not exist (atleast in Windows). A bit safer option may be $TEMP. I do not know of \ifmiktex switch, but I am sure TeXLive on windows will not set it to true.

There is such a command in pdfTeX-1.40 but I don't remember the name (I think it's "\ifshellescape"). Cheers, Peter -- http://pmrb.free.fr/contact/

\ifeof18 From the t-lilypond sources: %D If \type{\ifeof18} creates an error for you, your pdfetex is too old. %D (\type{\ifeof18} checks whether \type{\write18} is disabled.)

grep shellescape *.tex core-job.tex:\ifx\pdfshellescape\undefined \else core-job.tex: \chardef\systemcommandmode \ifcase\pdfshellescape \plusone \else \plustwo \fi
so \systemcommandmode is your friend -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Wait! So many alternatives that I'll have to create another function to choose one of them randomly ;) Thanks a lot, (I'll use \systemcommandmode then), Mojca

What exactly is the advantage of using \pdfshellescape over \ifeof18 as the basis of \systemcommandmode? The second one works in XeTeX as well while the first is only good for pdfTeX, but perhaps there are other reasons for using it. Thanks, Mojca

write 18 is a hack and pdfshellescape a sane replacement in luatex it will probably be gone completely since there we have \directlua 0 { os.execute("...") } Hans
