allow directory path as url

[tcaduser]

This patch allows the use of a local directory path for the url in a recipe.

For example, when building a local c extension, it is then possible to use a directory url, instead of having to contact the server:

    url = '/home/jsanchez/git/devsim'

I was encountering many difficulties using the git+https scheme and it was slowing down development time.

Did file:\\ not work?

Did file:// not work?

no, the recipe.py file does not parse the file:\\ scheme, and I am processing a directory and not a file.

The kivy-ios project accepts a local directory as a url, so I would argue that it should be consistent in python-for-android.

Thanks for the contribution :pray: I haven't used it in a while and I don't know if it's documented, but don't we already support local recipes via --local-recipes? https://github.com/kivy/python-for-android/blob/v2023.09.16/pythonforandroid/toolchain.py#L319-L322

Also since you're touching a core component, do you mind updating the tests to match this feature?

[HyTurtle]

Pair that with: https://github.com/kivy/buildozer/blob/937a076dbfd77864bd3eabdc2831c00bc2ca2e4b/buildozer/default.spec#L47-L50

Effectively export P4A_devsim_DIR=path

[tcaduser]

Hi @HyTurtle

export P4A_devsim_DIR=$HOME/git/tmp/devsim

seems to work. I was not able to get:

requirements.source.kivy = /home/jsanchez/git/tmp/devsim

to work. I suppose it is supposed to be requirements.source.devsim? (Still waiting for the environment variable based build).

Can you let me know if this is the official documentation: https://buildozer.readthedocs.io/en/latest/specifications.html

Please let me know the documentation repository, and I'll file a pull request with documentation.

It would indeed be requirements.source.devsim in the buildozer spec, posted the export line as that's how p4a reads it, and this is the p4a repo.

I'll have a look to see where/how well that's documented (ultimately it may currently just be the spec comments)

[tcaduser]

@HyTurtle your solution works for me so i will cancel this pull request
