Completion for file-paths/directories about click-completion HOT 3 CLOSED

I don't think there is currently a great way to do that. That definitely something that would be nice, if someone wants to give it a try!

For now, in our private application, we are completing with both the directory name and the directory name with a trailing slash:

$ myapp d<tab>
dir1
dir1/
dir2
dir2/

because there are two entries that begin exactly the same, the completion is done up to the full dir name, without the slash, and without space, so it is possilbe to continue the completion process.
Obviously the drawback is that the completion list is polluted by twice the amount of entries…

Ah, nice workaround, thanks! Will use that for now.

Hi @makkus and @glehmann , could you give a more complete example on how def complete .. is used to perform filename completion?

I use the fish shell and the autocompletion is currently useless to me since filenames are not completed :/

p.s. It seems that

from glob import glob
import click

complete_filenames = click.Choice(glob("**", recursive=True))

...
@click.argument("filename", type=complete_filenames)
...

does the job for me. Anyway if you have other suggestions, please let me know. Thanks!

p.p.s it does only when the directory tree is too large.

p.p.p.s this seems to be sufficient and doesn't require glob or anything:

complete_filenames = click.Path(exists=True)

p.p.p.p.s. only on fish 2.2.0 though, I noticed. I tried to understand changes in the fish completion API after 2.2.0, but did not come too far until now. Any ideas?
