Is there a way to make a file that always recompiles?

I have a file that returns some information about the current release for our application, such as the git hashref, etc.

Is there a way to tell mix that a particular file should always be recompiled so that this never becomes stale during development?

Use @external_resource on something relevant like the application module. :slight_smile:

Fwiw i just tried @external_resource "/dev/random" and sadly it didn’t work

Oh right! I had it backwards!

Well you could add a custom compiler to the compiler stage that runs before elixir and just delete that compiled file, or touch's it or whatever. :slight_smile:

I don’t remember what, if anything I did for this, but I’m wondering if @external_resource ".git/HEAD" might work… (or whatever recipe is necessary to make that happen).

(Actually, it might be necessary to read the .git/HEAD to see the ref: to which it refers, e.g., .git/refs/heads/master.)

This is a ~95% solution, as it looks like it expects to be a file, and not something transient. If it were possible to specify @external_resource true, that would probably solve my particular use-case.
