I read this (way too late) last night and slept over it. Together with
your comment on the `fmt-merge-msg` patch, I think you are really on to
something: we need _two_ config settings, as there are two distinct
concepts at play here:
- One setting to specify the default branch name for newly-initialized
repositories (such as `git init`, unless it re-initializes, and `git
clone` when the cloned repository does not yet contain any branches).
This should probably be called `init.defaultBranchName` (even if `git
clone` picks it up, too), and be overrideable by
`GIT_TEST_DEFAULT_BRANCH_NAME`.
- And another one, to define the default branch name for the _current_
repository. This setting would be configured implicitly upon `git init`
and `git clone`. For repositories where it is not set, we would assume
`master` for backwards-compatibility.
Technically, this should probably not even be a config option because it
is _strictly_ per-repo. But maybe it is not _so_ much per-repo: if I
want to rename all my main branches in all of my local repositories, I
might opt to configure this in `~/.gitconfig`.
Maybe a good name for this would be `repo.mainBranch` (and it would
contain the full ref name, e.g. `refs/heads/main`, not just `main`).
And then `git fmt-merge-msg` (and your proposed `git var` addition, which
I like a lot, maybe `git var mainBranch`?) will pick up the latter.
That way, existing repositories would not be affected by
`GIT_TEST_DEFAULT_BRANCH_NAME` or `init.defaultBranchName` at all. Only
new repositories would pick it up.
Does that sound like a plan?
Ciao,
Dscho
