0004992: an ocamldep aware of files with other suffixes than .ml / .mli ?

Notes
(0005731) xclerc (developer) 2010-12-08 10:29	Could you be more specific about the intended behavior of an "-impl-suffix" flag? Notice that the "-intf-suffix" flag you are referring to replace the default ".mli" suffix of interface file with a new suffix, it does not add new suffixes to be treated in the same way ".mli" is. From you report, I incline to think you would like to have the latter behavior rather than former one, but in that case the behavior would not be coherent with the one of the compilers. I the meantime, as you may already know, it is possible to overcome the problem by using the "-impl" and "-intf" flags of "ocamldep".

(0005745) letouzey (reporter) 2010-12-20 18:29	Hi xavier, Indeed, being able to allow new possible suffixes (such as ".ml4") in addition to the default ".ml" would be more interesting than just replacing ".ml" by something else. I didn't noticed that the "-intf-suffix" of ocamlc was meaning "forget about .mli and consider only ...". The idea is just to enhance a bit the lookup of local modules needed by foo.ml: if foo.ml mentions Bar, ocamldep foo.ml will mention bar.cm{o,x} only if bar.ml is found around (same place or via -I). If bar.ml isn't found, ocamldep doesn't complain and writes no deps, probably assuming that Bar is somewhere in the stdlib. This feature wish is about allowing to search for more than just bar.ml, say bar.ml4. And this bar.ml4 might not be pristine ocaml syntax, normally only its existence is meaningful here. A more explicit name for this option would then be something like --add-impl-suffix-to-lookup Concerning -impl and -intf, to my understanding they are only of limited help here: ok, they can be used when the whole bunch of files is given at once to ocamldep, typically to create a unique .depend. But here we try to rather create one .d dependency file per source file, a bit like ocamlbuild, hence running multiple instances of ocamldep and giving them only one file name at a time. Best regards, Pierre PS: something surprised me when doing quick tests about this "-impl". echo "let x = 1" > a.ml4 echo "let y = A.x" > b.ml ocamldep -impl a.ml4 b.ml With my ocaml 3.11.2 here, the output is a.cmo: a.cmx: b.cmo: b.cmx: Doesn't that sound like a bug, or am I missing something ?

It happens that my workaround suggestion is actually broken: '-impl' says 'process me as an implementation file', not 'treat me as an implementation while trying to discover dependencies'. This reinforces the usefulness of the switch you are requesting.

(0005754) xclerc (developer) 2011-01-04 12:01	Two command-line options have been added ('-ml-synonym' and '-mli-synonym') to allow one to define alternative suffixes for implementation and signature files. Both options should be followed by an extension with a leading dot (e. g. "-ml-synonym '.ml4'").
