Hi all,

I realize this isn’t generally an aim for guix proper, but I’d like
to be able to build a package from a local git repository (or
optionally from a local tar ball). In my specific case, it’s while
working out the packaging of a project I intend to publish but
haven’t published yet.

What I have working so far uses local-file, as below:

(define-public puzzledb-tools
  (package
    (name "puzzledb-tools")
    (version "20190625-git")
    (source
      (local-file
        "/home/rob/puzzledb/tools"
        #:recursive? #t))
  …

That’s a bit annoying because it includes stale files that happen
to be in the directory, it doesn’t check the hash, etc. Using a
git origin with a local path doesn’t work for reasons I don’t
completely understand — I think it’s because the guix-daemon builds
in a namespace without access to the local filesystem. Perhaps there’s
a way to link the git repository into that namespace?

Any hints appreciated!

Robert

If you're running the Guix system, you can setup a local git daemon that
serves your user's repos. Here's what I have in my config:

```
(git-daemon-service
  #:config (git-daemon-configuration
             (export-all? #t)
             (user-path ""))) ;; To allow access to '~rob/puzzledb/tools'
```

And then I /think/ you should be able to do something like:

```
(origin
  (method git-fetch)
  (uri (git-reference
        (url "git://localhost/~rob/puzzledb/tools")
        (commit "<hash>")))
  (sha256
   (base32
    "<hash>")))
```

Note that's off the top of my head, I personally use this publish
channels in my local network rather than package sources, but I can't
think why this wouldn't work too!

I typically just use (source "/some/repository"), though I don't
remember whether it automatically creates a fixed-output derivation for
the directory in question.  Probably not.

(local-file ...) should, though (I think); but you'll have to trick it
into ignoring ".git" by passing it a #:select? predicate.

FWIW that’s what ‘--with-source’ does.

Like Marius wrote, you could pass #:select?

  (local-file …
              #:select? (git-predicate "/home/rob/puzzledb/tools"))

Build processes for origins work in the global namespaces, with access
to the network and to everything.  So I think something like this should
work:

  (origin
    (method url-fetch)
    (url "/home/rob/puzzledb/tools")
    (sha256 …))

HTH!
