`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.
"Bookmark changes" sounds like changes will be bookmarked, and "Bookmark" here
is redundant. If we add support for pushing tags, this message will have to be
generalized anyway.
This makes it easier to work with multiple remotes at once while
tracking the default branch of the remote used to create the local
repository:
```shell
$ jj git clone --remote upstream https://github.com/upstream-org/repo
$ cd repo
$ jj git remote add origin git@github.com:your-org/repo
$ jj config set --repo git.fetch upstream
```
In the example above, `upstream` is the repository containing the
reference source code that you might want to patch, while `origin` is
your fork where pull-request will be pushed. The branch `main@upstream`
will be tracked.
This is basically "log -p" for "op log". The flag name has "op" because --diff
and --patch mean a similar thing in this context. Since -p implies --op-diff,
user can just do "op log -p" if he's okay with verbose op + content diffs.
Note that --no-graph affects both "op log" and "op diff" parts.
We might want to do some style changes later, such as inserting/deleting blank
lines, highlighting headers, etc.
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.
It's a pretty frequent request to have support for turning off
auto-tracking of new files and to have a command to manually track
them instead. This patch adds a `snapshot.auto-track` config to decide
which paths to auto-track (defaults to `all()`). It also adds a `jj
track` command to manually track the untracked paths.
This patch does not include displaying the untracked paths in `jj
status`, so for now this is probably only useful in colocated repos
where you can run `git status` to find the untracked files.
#323
I'm thinking of adding an option to embed operation diffs in "op log", and
"op log" shouldn't fail at the root operation. Let's make "op diff"/"show"
also work for consistency.
This flag implements three modes:
- `copy`: copy sparse patterns from parent
- `full`: do not copy sparse patterns from parent
- `empty`: clear all paths, equal to `set --clear`
This is useful for various tooling like tools that want to run a parallel
process that queries the build system (without running into locks/blocking.)
I think continuing to copy sparse patterns makes sense as the default behavior.

This enables workflows like "insert a commit that reformats the code in one of
my project directories".
`jj fix --include-unchanged-files` is an easy way to fix everything in the repo.
`jj fix --include-unchanged-files <file...>` fixes all of the `<files>` even if they are
unchanged.
This is mostly orthogonal to other features, so not many tests are added.
This is a significant and simple enough improvement that I think it's
appropriate to make it here instead of waiting for a `jj run`-based solution.
It seems everyone agrees that `obslog` is not an intuitive name. There
was some discussion about alternatives in #3592 and on #4146. The
alternatives included `evolution`, `evolutionlog`, `evolog`,
`rewritelog`, `revlog`, and `changelog`. It seemed like
`evolution-log`/`evolog` was the most popular option. That also
matches the command's current help text ("Show how a change has
evolved over time").
As reported in #4394, at least `test_show_command::test_show_basic`
can fail when run with a narrow terminal. This patch sets
`COLUMNS=100` in the environment when running tests so the CLI uses
that value instead of using the width of the user's terminal.
Right now, renamed and copied files don't have any color in the output
of `jj status`, and it makes them stand out. I think it's reasonable to
color renamed files the same as modified files, since renaming is like
modifying the path, and to color copied files the same as added files,
since they're basically just added files that happen to have similar
contents to an existing file.
"Concurrent" operations are not necessarily actually concurrent, so
"divergent" seems like a better name. And "reconcile" seems like a
better term for merging them, though we also sometimes use "merge".
I played with max-inline-alternation = 3 for a couple of weeks, and it's pretty
good. I think somewhere between 2 and 4 is good default because one or two
remove + add sequences are easy to parse.
If movement commands don't find a target commit, they fail. However,
it's usually not intuitive why they fail because in non-edit mode the
start commit is the parent of the working commit.
Adding the start commit change hash to the error message makes it easier
for the user to figure out what is going on.
Also, specifying 'No **other** descendant...' helps make it clear what
`jj` is really looking for.
Part of #3947
In this patch, I use the number of adds<->removes alternation as a threshold,
which approximates the visual complexity of diff hunks. I don't think user can
choose the threshold intuitively, but we need a config knob to try out some.
I set `max-inline-alternation = 3` locally. 0 and 1 mean "disable inlining"
and "inline adds-only/removes-only lines" respectively.
I've added "diff.<format>" config namespace assuming "ui.diff" will be
reorganized as "ui.diff-formatter" or something. #3327
Some other metrics I've tried:
```
// Per-line alternation. This also works well, but can't measure complexity of
// changes across lines.
fn count_max_diff_alternation_per_line(diff_lines: &[DiffLine]) -> usize {
diff_lines
.iter()
.map(|line| {
let sides = line.hunks.iter().map(|&(side, _)| side);
sides
.filter(|&side| side != DiffLineHunkSide::Both)
.dedup() // omit e.g. left->both->left
.count()
})
.max()
.unwrap_or(0)
}
// Per-line occupancy of changes. Large diffs don't always look complex.
fn max_diff_token_ratio_per_line(diff_lines: &[DiffLine]) -> f32 {
diff_lines
.iter()
.filter_map(|line| {
let [both_len, left_len, right_len] =
line.hunks.iter().fold([0, 0, 0], |mut acc, (side, data)| {
let index = match side {
DiffLineHunkSide::Both => 0,
DiffLineHunkSide::Left => 1,
DiffLineHunkSide::Right => 2,
};
acc[index] += data.len();
acc
});
// left/right-only change is readable
(left_len != 0 && right_len != 0).then(|| {
let diff_len = left_len + right_len;
let total_len = both_len + left_len + right_len;
(diff_len as f32) / (total_len as f32)
})
})
.reduce(f32::max)
.unwrap_or(0.0)
}
// Total occupancy of changes. Large diffs don't always look complex.
fn total_change_ratio(diff_lines: &[DiffLine]) -> f32 {
let (diff_len, total_len) = diff_lines
.iter()
.flat_map(|line| &line.hunks)
.fold((0, 0), |(diff_len, total_len), (side, data)| {
let l = data.len();
match side {
DiffLineHunkSide::Both => (diff_len, total_len + l),
DiffLineHunkSide::Left => (diff_len + l, total_len + l),
DiffLineHunkSide::Right => (diff_len + l, total_len + l),
}
});
(diff_len as f32) / (total_len as f32)
}
```
* We started with a tristate flag where:
- Auto - Maintain current behaviour. This edits if
the wc parent is not a head commit. Else, it will
create a new commit on the parent of the wc in
the direction of movement.
- Always - Always edit
- Never - Never edit, prefer the new+squash workflow.
However, consensus the review thread is that `auto` mode where we try to infer when to
switch to `edit mode`, should be removed. So `ui.movement.edit` is a boolean flag now.
- true: edit mode
- false: new+squash mode
* Also add a `--no-edit` flag as the explicit inverse of `--edit` and
ensure both flags take precedence over the config.
* Update tests that assumed edit mode inference, to specify `--edit` explicitly.
NOTE: #4302 was squashed into this commit, so see that closed PR for review history.
Part of #3947
The code in both cli/src/commands/{next,prev}.rs is identical except
for the direction of movement. This commit pull the parts that make
sense out into cli/src/movement_util.rs so it's easier to see the
differences.
Part of #3947
Add gratuitous `jj log` output to more points in the tests.
This makes it easier to understand the intended changes
by literally visualizing the commit tree we are after each movement.
This is at least useful for me since I find the new+squash workflow
confusing.
Test behaviour is not changed.
