[Caml-list] how to automatically extract a subset of some ocaml code base?

[Caml-list] how to automatically extract a subset of some ocaml code base?

[Francois BERENGER]

Hello,

I have a large research prototype code base, with many tested, compiling
but abandoned things.

I'd like to release only a small cool stuff out of it.

I have an executable with an entry point into that code base
to use the cool stuffs.

Is there a tool that would allow me to extract only the
needed source code so that I can do a minimal source-based release with
only "cool stuff" plus all its dependencies?

Previously, I would do this by hand. But, with years passing, I become
more and more lazy. :)

Thanks,
F.

Hi Francois,

I am currently working on a refactoring tool for OCaml.

     https://gitlab.com/trustworthy-refactoring/refactorer

It contains functionality to compute the file dependency graph of a 
codebase, so perhaps this would potentially work for you? If you have 
the dependency graph, you can extract only the source files that the 
entry point (transitively) depends on.

It is not especially user-friendly at the moment, but if you like I 
could work with you on getting it to do what you want.

Interesting tool. So yes, indeed I am asking for a refactoring tool for ocaml.
If anyone has a good knowledge about such tools for ocaml, a mini
review would be welcome.

The file level is a little bit too coarse.

I would like to extract all the functions callable from the main() and
dump all them in bottom up order into a new file (that I hope to
compile).

By the way, maybe the resulting executable from compiling such a
single minimalist file would be quite small.
Interesting secondary effect of the approach.

Maybe, what I need is called a reachability analysis by the experts.

Here is a wish:
orefactor --minimize -i src/main.ml --entry-point 'main()' -o src/mini.ml

F.

I'm not sure, but I think this is part of what js_of_ocaml does.
