[opam-devel] opam pinning to local repo

[Anil Madhavapeddy]

I wonder if you've been bitten by the git/local autodetection.  OPAM 1.2b4 spots that the local directory that you're pinning to is a git repository, and turns it into a git remote instead.  if you haven't committed the `opam` file to the local git, then it won't be seen by opam.

Can you try

opam pin -k local add foo ~/code/foo

and see if you get the expected behaviour of using the existing opam file?

This is the OPAM issue for the autodetection:

If this is indeed your bug, I'm of the firmer notion that this smart probing should be deactivated before the final release.

However, opam doesn't detect the opam file, and instead says "package not defined, would I like to define a new package". At this point you have to answer yes, and opam creates a new opam file, which is not what I want.

Then I would first add this as a repo and also pin to this directory. I'm trying to avoid the first part; I shouldn't have to add a repo per package.
