… environment variable.

Status

READY

Description

This feature enables usage of file path's for --token and corresponding env vars GHORG_*_TOKEN.

I am by far not a go programming expert, but I testet this feature with the --token and the GHORG_*_TOKEN environment variable. Either with the token itself and with a path given.

If this feature is ok enough, I will also add documentation.
I am not sure how to write a test for this feature, if someone can guide me, I would also add some tests.

closes #356

Thanks for the PR! At a glance it looks good but will take a closer look once I have some time.

That'll be great! I added documentation.

If this will work I would also add this feature to --base-url, I want to use ghorg to sync also my works repos, but it is not allowed make the URL public, therefore encrypting it and use the file as the source.
The positive side, everything is implemented to do that. ;-)

Hope to here from you soon. Thank's!
