It tries to push all deleted branches, but can only succeed for tracked
branches.
Closes#2946, as there's probably no need to have `--deleted --tracked`
that would only be different in that the warnings wouldn't be printed.
Thanks to @yuja for pointing this out.
Our virtual file system at Google (CitC) would like to know the commit
so it can scan backwards and find the closest mainline tree based on
it. Since we always record an operation id (which resolves to a
working-copy commit) when we write the working-copy state, it doesn't
seem like a restriction to require a commit.
When the user doesn't have a configured default command, we show a
hint saying to set `ui.default-command`. I think the user is very
likely to want to set that in the user-wide config, so let's include
the command in the hint.
I'll probably add infix logical operators later, but the surround() function
is still useful because we don't have to repeat the condition:
if(x || y, "<" ++ separate(" ", x, y) ++ ">")
surround("<", ">", separate(" ", x, y))
It can't be used if we want to add placeholder text, though:
if(x || y, "<" ++ separate(" ", x, y) ++ ">", "(none)")
Closes#2924
This reimplements the change 9faa4670d5 "cli: on init, import git refs prior
to importing HEAD." Initialization is special because the HEAD ref isn't
available to jj yet, and there is an empty working-copy commit.
The initialization function could be refactored to go through the common code
path, but I think doing that would make future improvement harder. We might
want to initialize tracking branches based on .git/config for example.
Fixes#2942
This initializes a git backed repo.
* It does the same thing as `jj init --git` except that it
has a --colocated flag to explicitly specify that we want
the .git repo to be side-by-side the .jj repo in the working
directory.
* `jj init --git` will keep the current behaviour and will not
be able to create colocated git backed repos.
* Update test snapshots.
A few minor updates after 0f27152 AKA #2945
Specifically, I tried to change the help text so that it looks better as
Markdown. I also reworded the deprecation warning and added a hint.
this has two main advantages:
- it makes it clear that the shells are mutually exclusive
- it allows us to extend the command with shell-specific options in the future if necessary
as a happy accident, it also adds support for `elvish` and `powershell`.
for backwards compatibility, this also keeps the existing options as hidden flags.
i am not super happy with how the new help looks; the instructions for setting up the shell are
squished together and IMO a little harder to read. i'm open to suggestions.
it's somewhat confusing to me that the `--bash` flag exists at all, since it does nothing - maybe it makes sense to give a hard error? or just remove the flag?
but in any case, it seems good to document the existing behavior.
previously, `jj diff` would show the full contents of binary files such as images.
after this change, it instead shows "(binary)". it still shows the filename and metadata so that
users can open the file in the viewer of their choce.
future work could involve showing binary files as Sixel or similar; finding a way to compare large
non-binary files without filling up the screen; or extending the data backends to avoid having to
read the whole file contents into memory.
Previously, `jj git push; jj git push` would tell the user that "No
branches point to the specified revisions.". I found this confusing,
even though strictly speaking it is correct (as the default revset only
considers revisions that haven't been pushed to the remote).
Closes#2241
The error output gets more verbose because all gix error sources are printed.
Maybe we'll need a better formatting, but changing to multi-line output doesn't
look nice either.
These error types are special because the message is embedded in ASCII art. I
think it would be a source of bugs if some error types had ": {source}" but
others don't. So I'm going to remove all ": {source}"s, and let the callers
concatenate them when needed.
Summary: As discussed in Discord, on GitHub, and elsewhere, this change
deprecates the use of `jj merge` and suggests users use `jj new` exclusively
instead. `merge` isn't completely unfit as a name; but we think it obscures
the generality of `new` and we want people to use it instead.
To further drive the bit home, by default, `jj merge` is now hidden. This will
hopefully stop new users from running into it.

Summary: As discussed in Discord, on GitHub, and elsewhere, this change
deprecates the use of `jj checkout` and suggests users use `jj new` exclusively
instead. The verb `checkout` is a relic of a bygone era the — days of RCS
file locking, before 3-way merge — and is not a good, fitting name for the
functionality it provides.
To further drive the bit home, by default, `jj checkout` (and `jj co`) is now
hidden. This will hopefully stop new users from running into it.

These didn't really need to use `jj checkout`, and it will be deprecated in a
future change anyway. Move them out of there and into `new`.
Ideally this would go into `test_conflicts.rs`, but that exists in `jj-lib`, so
it doesn't have `TestEnvironment` available to it.

* Move git_init() to cli/src/commands/git.rs and call it from there.
* Move print_trackable_remote_branches into cli_util since it's not git specific,
but would apply to any backend that supports remote branches.
* A no-op change. A follow up PR will make use of this.
* Create a git_init() function in cli/src/commands/init.rs where all git related work is done.
This function will be moved to cli/src/commands/git.rs in a subsequent PR.
I'm going to rewrite the error output to print source chain one by one.
The "{message}: {err}" pattern is wrapped in an error struct. InternalError
variant could be a { message, source } pair, but not all errors need an
additional message. This will also apply to UserError.
This prevents rust doctests from trying to compile the code blocks.
I don't think we use doctests much or at all, but I'd like
`cargo insta test --test-runner nextest --accept --workspace`
to pass.
Unfortunately, this affects the output of `jj help` as well, but I
can't think of a workaround for that.
I am using a very hacky approach, using `insta` to generate the markdown help.
This is based on a lucky coincidence that `insta` chose to use a header
format for snapshot files that MkDocs interprets as a Markdown header (and
ignores).
I considered several other approaches, but I couldn't resist the facts that:
- This doesn't require new developers to install any extra tools or run any
extra commands.
- There is no need for a new CI check.
- There is no need to compile `jj` in the "Make HTML docs" GitHub action,
which is currently very fast and cheap.
Downside: I'm not sure how well MkDocs will work on Windows, unless the
developer explicitly enables symbolic links (which IIUC is not trivial).
### Possible alternatives
My next favorite approaches (which we could switch to later) would be:
#### `xtask`
Set up a CI check and a [Cargo `xtask`] so that `cargo xtask cli-help-to-md`
essentially runs `cargo run -- util markdown-help > docs/cli-reference.md` from
the project root.
Every developer would have to know to run `cargo xtask cli-help-to-md` if
they change the help text.
Eventually, we could have `cargo xtask preflight` that runs `cargo +nightly
fmt; cargo xtask cli-help-to-md; cargo nextest run`, or `cargo insta`.
#### Only generate markdown for CLI help when building the website, don't track it in Git.
I think that having the file in the repo will be nice to preview changes to
docs, and it'll allow people to consult the file on GitHub or in their repo.
The (currently) very fast job of building the website would now require
installing Rust and building `jj`.
#### Same as the `xtask`, but use a shell script instead of an `xtask`
An `xtask` might seem like overkill, since it's Rust instead of a shell script.
However, I don't want this to be a shell script so that new contributors on
Windows can still easily run it ( since this will be necessary for the CI to
pass) without us having to support a batch file.
#### Cargo Alias
My first attempt was to set up a [cargo alias] to run this, but that doesn't
support redirection (so I had to change the `jj util` command to output to a
file) and, worse, is incapable of executing the command *in the project root*
regardless of where in the project the current directory is. Again, this seems
to be too inconvenient for a command that every new PR author would have to run
to pass CI.
Overall, this just seems a bit ugly. I did file
https://github.com/rust-lang/cargo/issues/13348, I'm not really sure that was
worthwhile, though.
**Aside:** For reference, the alias was:
```toml
# .cargo/config.toml
alias.gen-cli-reference = "run -p jj-cli -- util markdown-help docs/cli-reference.md"
```
### Non-alternatives
#### Clap's new feature
`clap` recently obtained a similarly-sounding feature in
https://github.com/clap-rs/clap/pull/5206. However, it only prints short help
for subcommands and can't be triggered by an option AFAICT, so it won't help us
too much.

[cargo alias]: https://doc.rust-lang.org/cargo/reference/config.html#alias
This uses the [`clap-markdown`] library. It's not very flexible, but seems to
work. Its implementation is not difficult. If needed, we could later
reimplement the part that iterates over all subcommands and have a different
output (e.g., the boring version of each help text inside its own code block,
or a different file per subcommand, or some fancy template in handlebars or
another rust-supported templating language). I don't want to do it right now,
though.
The library does turn out to have some annoying bugs, e.g.
https://github.com/ConnorGray/clap-markdown/pull/18, but I think that's not a
deal-braker. The fix seems to be 3 lines; if the fix doesn't get merged soon, we
could vendor the library maybe?

GitBackend::gc() will need to check if a commit is reachable from any
historical operations. This could be calculated from the view and commit
objects, but the Index will do a better job.
The "::HEAD" set is usually smaller than "::git_refs". If these sets were
imported in that order, "HEAD..git_refs" commits would be indexed on top of
the "::HEAD" commits. It's not a problem, but undesirable.
