`npins add github` Should be able to resolve the default branch

[Gerg-L]

Since the mass migration of people away from the original default of using master as the de-facto name for the main working git branch it's been a guess on what the name of the branch you probably want is.

npins add github should be able to resolve a default branch, either when --branch is supplied with no arguments. or with a separate flag.

The latter would be more explicit and have no possibility of breaking any legacy code so I'd vote for that

Isn't that something that git can natively do? Do you have a CLI way of obtaining the default branch name (without cloning)?

git remote show <REPO> | sed -n '/HEAD branch/s/.*: //p' would do it. i thought it would be a nice convenience feature though.

npins already has an fetch_default_branch function in git.rs as well so i think it'd be fairly easy

yes, i implemented this way back to make the flake import feature work, since flakes are allowed to refer to default branches (see also some discussion in #114 about whether we should have default branches as a general feature of npins, too)
