Subject: [Caml-list] cppo and camlp4 ? which way to go ?
Date: Wed, 10 Jul 2013 04:03:06 +0200 [thread overview]
Message-ID: <1373421379-sup-8981@nixos> (raw)
It looks like ocaml supports only one -pp option?
Now I want both: first cppo, then camlp4?
Which way to go?
way 1) find a way to make ocaml accept multiple -pp
way 2) KISS: -pp 'cppo | camlp4', unlikely to work, because -pp adds the
input file as last argument?
Well - could be using -pp 'sh -c "cppo $1 | camlp4 $1 ..." '
that's linux, only, starting quoting hell
way 3)
make cppo accept additional options, and make it call camlp4 and pass
its data to it
3.1: using a file: batteries includes with_temp_file, but would add
new dependencies
3.2: pipe through command, which cross platform implementation does
exist?
way 4) rewrite my tracing code to use new -ppx (would take too long ?)
Have I missed a simple solution ?
I appologize if I've missed the obvious.
