We no longer guess the head repository using heuristics; instead, we
present the user with the choice of pushable repositories and an
additional option to create a new fork.
The new `pr create --head` flag is available for the user to specify the
head branch in `branch` or `owner:branch` format and completely skip any
forking or auto-pushing checks.
On first run in a git repository, `BaseRepo()` will now prompt the user
which repository should be queried as base repository if there are
multiple git remotes or when we are in the context of a fork.
In non-interactive mode, the prompt is skipped and we default to the
first git remote instead.
After the base repo is resolved, the result is cached in the local
repository using `git config` so that RepositoryNetwork API lookups can
be avoided in the future.
Accept the "HOST/OWNER/REPO" syntax or passing a full URL for both the
`--repo` flag and the GH_REPO environment variable and allow setting
GH_HOST environment variable to override just the hostname for
operations that assume "github.com" by default.
Examples:
$ gh repo clone example.org/owner/repo
$ GH_HOST=example.org gh repo clone repo
$ GH_HOST=example.org gh api user
$ GH_HOST=example.org gh gist create myfile.txt
$ gh issue list -R example.org/owner/repo
$ gh issue list -R https://example.org/owner/repo.git
$ GH_REPO=example.org/owner/repo gh issue list
This fixes a regression where extra git remotes pointing to
non-github.com hostnames could result in gh trying to parse repository
information from them.
Previously we would trigger OAuth flow when the config file did not
exist. Now we will let an empty Config object be initialized in that
case, but trigger OAuth flow when the Context caller requests an
AuthToken.
