This adds a revert command which is similar to backout, but adds the
`--destination`, `--insert-after`, and `--insert-before` optoins to
customize the location of the new reverted commits.
`jj backout` will subsequently be deprecated.
Closes#5688.
We could replace clap's "SuggestedSubcommand" instead of removing it,
but then the user might not notice that this is a custom suggestion and
not pay enough attention to it.
This uses the just-released https://github.com/clap-rs/clap/pull/5941.
There are alternative ways to solving the problem addressed by the next
commit, but they don't seem to preserve color well. So, let's have a
test to make sure future refactorings can tell whether this issue is
still relevant.
The main goal here is so that a completely new user that types in `jj
init` or `jj clone` gets a pointer to the correct command needed to try
out `jj`.
Aliases and `ui.default-command` are loaded before `--config` and
`--config-file` arguments are parsed (#5282).
There is supposed to be a warning when the result of these arguments
would change the parsed args: #5286.
However, that warning was not being printed if the arguments failed to
parse due to an unrecognized subcommand. Example:
```bash
# correct:
$ jj --config ui.default-command=nonsense
Warning: Command aliases cannot be loaded from -R/--repository path or --config/--config-file arguments.
# previous, confusing:
$ jj --config aliases.some-alias=nonsense some-alias
error: unrecognized subcommand 'some-alias'
# now:
$ jj --config aliases.some-alias=nonsense some-alias
Warning: Command aliases cannot be loaded from -R/--repository path or --config/--config-file arguments.
error: unrecognized subcommand 'some-alias'
```
I'm going to add "[EOF]" marker to test that command output is terminated by
newline char. This patch ensures that callers who expect a raw output string
would never be affected by any normalization passes.
Some common normalization functions are extracted as CommandOutputString
methods.
With this change a warning is shown if the user does not explicitly specify the target revision, but the behavior is unchanged (it still defaults to the working copy).
In the future the warning will be turned into an error. In other words, it will be required to specify target revision.
The bulk of the changes here are to prepare tests for the upcoming change, to make the transition easier.

This patch does not change the handling of inline tables yet. Both inline and
non-inline tables are merged as before. OTOH, .set_value() is strict about table
types because it should refuse to overwrite a table whereas an inline table
should be overwritten as a value. This matches "jj config set"/"unset"
semantics. rules_from_config() in formatter.rs uses .as_inline_table(), which is
valid because toml_edit::Value type never contains non-inline table.
Since toml_edit::Value doesn't implement PartialEq, stacking tests now use
insta::assert_snapshot!().
`jj bookmark` is a frequently used command. Its subcommands already have
one letter aliases. Defining `jj b` as an alias for `jj bookmarks` make
bookmarks really easy to use.
Jujutsu's branches do not behave like Git branches, which is a major
hurdle for people adopting it from Git. They rather behave like
Mercurial's (hg) bookmarks.
We've had multiple discussions about it in the last ~1.5 years about this rename in the Discord,
where multiple people agreed that this _false_ familiarity does not help anyone. Initially we were
reluctant to do it but overtime, more and more users agreed that `bookmark` was a better for name
the current mechanism. This may be hard break for current `jj branch` users, but it will immensly
help Jujutsu's future, by defining it as our first own term. The `[experimental-moving-branches]`
config option is currently left alone, to force not another large config update for
users, since the last time this happened was when `jj log -T show` was removed, which immediately
resulted in breaking users and introduced soft deprecations.
This name change will also make it easier to introduce Topics (#3402) as _topological branches_
with a easier model.
This was mostly done via LSP, ripgrep and sed and a whole bunch of manual changes either from
me being lazy or thankfully pointed out by reviewers.
previously, aliases to built-in commands were silently ignored. this matches git's behavior, but seems unhelpful, especially if the user doesn't know that a command with that name already exists.
give a warning rather than silently ignoring it.
It's inconsistent that some warnings have headings and some don't, and it seems
the choice is arbitrary. Let's unify the style. There are two exceptions:
1. continued line following labeled message,
2. "unrecognized response" followed by prompt.
this greatly speeds up the time to run all tests, at the cost of slightly larger recompile times for individual tests.
this unfortunately adds the requirement that all tests are listed in `runner.rs` for the crate.
to avoid forgetting, i've added a new test that ensures the directory is in sync with the file.
## benchmarks
before this change, recompiling all tests took 32-50 seconds and running a single test took 3.5 seconds:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test test_working_copy'
Time (mean ± σ): 3.543 s ± 0.168 s [User: 2.597 s, System: 1.262 s]
Range (min … max): 3.400 s … 3.847 s 10 runs
```
after this change, recompiling all tests take 4 seconds:
```
; hyperfine 'touch lib/src/lib.rs ; cargo t --test runner --no-run'
Time (mean ± σ): 4.055 s ± 0.123 s [User: 3.591 s, System: 1.593 s]
Range (min … max): 3.804 s … 4.159 s 10 runs
```
and running a single test takes about the same:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test runner -- test_working_copy'
Time (mean ± σ): 4.129 s ± 0.120 s [User: 3.636 s, System: 1.593 s]
Range (min … max): 3.933 s … 4.346 s 10 runs
```
about 1.4 seconds of that is the time for the runner, of which .4 is the time for the linker. so
there may be room for further improving the times.
This partially reverts 6c627fb30d76 "cli: default to log when no subcommand is
provided." We could reject an empty alias at all, but we would still need to
ensure that the expanded alias contained a subcommand name.
The help output is a bit odd as the <COMMAND> can be omitted, but I think
that's acceptable. If we do care about that, maybe we can override_usage().
This is basically the same as Mercurial's workaround. I don't know about Git,
but arguments order is very restricted in git, so -C path can be parsed prior
to alias expansion. In hg and jj, doing that would be messy and unreliable.
Closes#2414
This is a naive implementation, which cannot deal with multiple children
or parents stemming from merges.
Note: I gave each command separate a separate argument struct
for extensibility.
Fixes#878
I've extracted the `builtin_log_root` template for users to customize the
default templates without fully overriding them, for example I would remove
the change_id/commit_id for myself - and we discussed in Discord that leaving
those makes sense for the user to be reminded/teached that the root commit has
a change id made from z's.
