`git.latest_tag` doesn't support relative paths

[garymm]

Putting:

source:
  path: ../

Works fine, and I'm using this in my recipe.

However, this does not work to get the tag:

context:
  version: ${{ git.latest_tag("../") }}

I've tried several variants:

• ../
• ../.git
• file://../
• file:/../
• file://../.git
• file:/../.git

None of them work.

I just had a look and I think we should rewrite thsi function a bit to use git for-each-ref locally (or git describe). But it's a bit tricky - especially git ls-remote doesn't allow us to sort by creatordate which would be more appropriate than sorting by 'version' inferred from the tag.

Basically the behavior is in most cases a bit ambigous. However if you run this as part of some script, you might have an easier time for now to just use an env var, e.g.

export GIT_TAG=$(git find the tag ...)

and then in the recipe you can just use

context:
  version: ${{ env.get("GIT_TAG") }}

You also don't need the --experimental flag in that case.

I have tried using both

context:
  name: xyz
  repo_url: [email protected]
  latest_tag: ${{ git.latest_tag( repo_url ) }}
  version: ${{ latest_tag }}

package:
  name: ${{ name|lower }}
  version: ${{ latest_tag }}

and

context:
  name: xyz
  # . is the repo root relative to where I'm executing rattler-build from
  latest_tag: ${{ git.latest_tag( "." ) }}
  version: ${{ latest_tag }}

package:
  name: ${{ name|lower }}
  version: ${{ latest_tag }}

Both give me a tag name, BUT it's not the latest tag. It seems to be the first tag in alphabetical order. The actual latest tag is 0.2.5

For reference, this is what git describe --tags returns: 0.2.5-114-g119568d8
