Setup output name from within ConTeXt document

Setup output name from within ConTeXt document

[Pascal Pascali]

Dear ConTeXt community,

Is it possible to set the file name of the output from within the document?
I can do it on the command line by adding --result="CustomName.pdf", but I'd need to do it according to certain variables in the content of the file itself...
Setupinteraction[title="CustomName.pdf"] will just set the internal pdf name, not the file system name.

Thank you for your help!

Best regards,
Pascal

You can set a different name at the first line of your document, e.g.

% result="newfilename"

but this is only a alternative to the result-argument on the command line.

With \setupinteraction you can set/change metadata values but not the 
file name.

assuming that your run file is old.tex:

\startluacode
luatex.wrapup(
     function()
         os.remove("new.pdf")
         os.rename("old.pdf","new.pdf")
     end
)
\stopluacode

\starttext

test

\stoptest

Many thanks for your reply, Hans.

Just a question, which is the gain of wrapping os.rename() in a function?

Many thanks for your help,

Pablo

I'm not sure how you would do it differently. If you would not wrap it, 
it would be done immediately and that's not what you want (and the pdf 
file might already be open). Think of def vs edef ... When a function is 
called its actions are done immediately.
