Hi,
I am making a survey intended to be open source, which means it needs to
compile everywhere, with minimal edits.
I use PDFtk for post-processing the PDF output, to include something
else in the PDF. This generates some temp files, that I don't want to
leave in the output folder, in case someone uses them by mistake, so I
want to delete them.
Windows and Linux/Mac use different syntax, but "system" is a blunt
tool, and does not seem to allow me to check which command to use:
system "del tempfile.pdf"
system "rm -f tempfile.pdf"
That generates an error message, and Therion thinks the file has failed
to compile when it is actually unimportant.
Is it possible to code branch, like this:
if( windows ) {
system "del tempfile.pdf"
} else {
system "rm -f tempfile.pdf"
}
Is it possible to tell Therion not to consider the result of a "system"
command when determining if compilation failed? Like using @system to
ignore the output.
Alternatively, does someone have a syntax of command that works on any
of these three platforms? This almost works, but Linux chucks junk into
a file called "nul" (even though it is not using that command):
del tempfile.pdf 2>nul || rm -f tempfile.pdf 2>/dev/null
And yes, I know I could demand installation of Python and clean up that
way, but it seems like such overkill when all I want to do is delete a
temp file. I would rather not add yet another dependency.
Cheers,
Tarquin
