I considered even changing the message to "Checking out: <commit>" as
that's technically more correct (the message is printed when the
view's checkout is updated, i.e. before the working copy is
updated). However, I worried that users would find it confusing that
e.g. `jj close` would result in a "Checking out: " message, even
though that's what actually happens.
I remember adding that message a long time ago so the user has a trace
of working copy commit ids in the terminal output. They should be able
to get the same information from the operation log combined with
e.g. `jj st --at-op`.
Perhaps it makes more sense to display the working copy commit just
above the changes in the working copy commit, even though that means
that the order between the working copy commit and the parent becomes
the opposite of the order in `jj log`.
"{:?}" escapes `\` to `\\` for Windows paths. That breaks tests checking
paths without using "{:?}". Use PathBuf::display() in both commands and
tests to get consistent output.
This fixes test_init_local, test_init_git_internal, and
test_init_git_external on Windows.
I'm preparing to publish an early version before someone takes the
name(s) on crates.io. "jj" has been taken by a seemingly useless
project, but "jujube" and "jujube-lib" are still available, so let's
use those.
It's annoying to have to have the Git repo and Jujube repo in separate
directories. This commit adds `jj init --git`, which creates a new
Jujube repo with an empty, bare git repo in `.jj/git/`. Hopefully the
`jj git` subcommands will eventually provide enough functionality for
working with the Git repo that the user won't have to use Git commands
directly. If they still do, they can run them from inside `.jj/git/`,
or create a new worktree based on that bare repo.
The implementation is quite straight-forward. One thing to note is
that I made `.jj/store` support relative paths to the Git repo. That's
mostly so the Jujube repo can be moved around freely.
