Description

Ocamlmig is a command line tool to rewrite ocaml source code, especially to make updating to newer interfaces easier.

Added to opam-repository:

README

ocamlmig is a command line tool for rewriting ocaml source code with access to scope and type information.

As a simple example of what it can do, let's say an opam-installed library A provides this interface:

val new_name : int -> int

val old_name : int -> int
[@@migrate { repl = Rel.new_name }]

and your repository contains a file b.ml:

let _ = A.old_name 1

then you could do:

$ git diff b.ml
$ ocamlmig migrate -w
$ git diff b.ml
-let _ = A.old_name 1
+let _ = A.new_name 1

Examples of real rewrites:

If that piqued your interest, you can find more information about what ocamlmig does, and using it.

This is work in progress, so many things are only partially implemented, but the existing functionality as is should still be interesting.

Build status

Results of building ocamlmig with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
