Yes, --result doesn’t work with directories, just filenames.

In my own Django app that uses ConTeXt, I just copy/generate all the needes files into one work directory per process.

i tried this without success :( the only workaround u've found for now is to render a tex file and copile it manually.

I have no clue what you do, but just running context should nto be that hard. And yes, you need a file (no piping of stdin) as there are normally multiple runs needes. Also, mkiv assumes that there is a file (tex, xml, ...) as it's actually an indirect process: if you run "context foo.tex" on the console you will see what gets actually called and the file loaded is "cont-yes.mkiv" which in turn will load whatever is needed as source.

i think i am one step closer to my goal. alla i have is to combine: 1- What Hans taught me about working on file (and not simply stdout) python has already a module *tempfile.NamedTemporaryFile()* , 2- Your snippet to run ConTeXT inside the temporary folder *cd && contextjit --purgeall --path="%d" --arguments=filename=%d/%e.pdf* *--result="%e-2UP.pdf" /home/ousia/A5-to-A4_landscape-booklet.tex* *​*To be adapted for a working example​ ( tomorrow i have a night shift so probably tuesday i will work on again). Thank you everybody!

Still working on the issue, i have a simple (comehow related) question: since the PDF generated is a binary, i can pipe it through the stdout ? no, because in some cases the file is rewritten (for instance the stream length is only known after the compressed stream is written and updated afterwards)
