Almost everyone calls the project "jj", and there seeems to be
consensus that we should rename the crates. I originally wanted the
crates to be called `jj` and `jj-lib`, but `jj` was already
taken. `jj-cli` is probably at least as good for it anyway.
Once we've published a 0.8.0 under the new names, we'll release 0.7.1
versions under the old names with pointers to the new crates names.
Typical query would be something like -r 'mine()' or -r 'branches()' to
exclude remote-only branches #1136.
The query matches against local targets only. This means there's no way to
select deleted/forgotten branches by -r option. If we add a default revset
configuration, we'll need some way to turn the default off.
The motivating use-case was this `jj signoff` script: https://gist.github.com/thoughtpolice/8f2fd36ae17cd11b8e7bd93a70e31ad6
Which includes lines like this:
```sh
NAME=$(jj config list user.name | awk '{split($0, a, "="); print a[2];}' | tr -d '"')
MAIL=$(jj config list user.email | awk '{split($0, a, "="); print a[2];}' | tr -d '"')
```
There is no reason that we should have to clumsily parse out the config values. This `jj config get` command supports scripting use-cases like this.
Use `br@git` instead.
Before, if there is not a local branch `br`, jj tried to resolve
it as a git ref `refs/heads/br`. Unchanged from before, `br` can
still be resolved as a tag `refs/tag/br`.
This doesn't change the way @git branches are stored in `git_refs` as opposed
to inside `BranchTarget` like normal remote-tracking branches. There are
subtle differences in behavior with e.g. `jj branch forget` and I'm not sure
how easy it is to rewrite `jj git import/export` to support a different
way of storage.
I've decided to call these "local-git tracking branches" since they track
branches in the local git repository. "local git-tracking" branches sounds a
bit more natural, but these could be confused with there are no remote
git-tracking branches. If one had the idea these might exist, they would be
confused with remote-tracking branches in the local git repo.
This addresses a portion of #1666
I think I will find this useful in at least two cases:
1. When you already have a branch pointing to some commit, it's easier
to do `jj git push -r xyz` than `jj git push --branch
push-xyzxyzyxzxyz`.
2. When you have a stack of changes, it's useful to be able to push
all of them at once.
I think we should also update the default behavior of `jj git push` to
be `jj git push -r 'remote_branches()..@'` or something like
that. That removes the ugliness of having a default behavior that the
user can't reproduce using flags. I'll leave that change for a
separate PR.
This was pretty simple. I simplified a bit by making the transaction
description mention only branches, not changes. It still mentions the
branches created for the changes, however. Also, since the operation
"tags" contain the full command line, I think it'll still be
relatively easy for the user to understand what the operation was
about.
Currently, if the user modifies a modify/delete conflict, we always
consider the result resolved. That happens because we materialize the
missing side of the conflict as an empty string but when we parse the
conflict, we expect only the number of sides in the input
conflict. For example, if the input is a regular modify/delete
conflict with one remove and one add, the materialized markers will
have one remove and two adds (one of them empty), but when we try to
parse it, we expect one remove and only one add. When we fail to parse
it, we consider it resolved.
This commit fixes the bug by using
`conflicts::Conflict<Option<TreeValue>>` and keeping track of which
sides were supposed to be empty. We could have fixed the bug without
switching to `conflicts::Conflict`, but we want to switch anyway, and
the fix happens naturally when switching.
`jj sparse` is a bit different from other commands in that its `jj
sparse --list` is practically a separate command. Let's make it an
actual subcommand for consistency, and so we can more cleanly add
additional flags for `jj sparse list` in the future. I moved all the
other arguments to `jj sparse set`. I'm not sure if `jj sparse set
--reset` would have been better as `jj sparse reset`, but it is
technically just updating the sparse patterns just like the other
arguments (`--clear`, `--add` , `--remove`).
This bug concerns the way `import_refs` that gets called by `fetch` computes
the heads that should be visible after the import.
Previously, the list of such heads was computed *before* local branches were
updated based on changes to the remote branches. So, commits that should have
been abandoned based on this update of the local branches weren't properly
abandoned.
Now, `import_refs` tracks the heads that need to be visible because of some ref
in a mapping keyed by the ref. If the ref moves or is deleted, the
corresponding heads are updated.
Fixes#864
This adds a config called `revsets.short-prefixes`, which lets the
user specify a revset in which to disambiguate otherwise ambiguous
change/commit ids. It defaults to the value of `revsets.log`.
I made it so you can disable the feature by setting
`revsets.short-prefixes = ""`. I don't like that the default value
(using `revsets.log`) cannot be configured explicitly by the
user. That will be addressed if we decide to merge the `[revsets]` and
`[revset-aliases]` sections some day.
I plan to add `revsets.short-prefixes` and `revsets.immutable` soon,
and I think `[revsets]` seems like reasonable place to put them. It
seems consistent with our `[templates]` section. However, it also
suffers from the same problem as that section, which is that the
difference between `[templates]` and `[template-aliases]` is not
clear. We can decide about about templates and revsets later.
The current behavior was introduced by 20eb9ecec1 "git: don't abandon
HEAD commit when it loses a branch." While the change made HEAD mutation
behavior more consistent with a plain ref operation, HEAD can also move on
checkout, and checkout shouldn't be considered a history rewriting operation.
I'm not saying the new behavior is always correct, but I think it's safer
than losing old HEAD branch. I also think this change will help if we want
to extract HEAD management function from git::import_refs().
Fixes#1042.
Establishing a unique file extension for the temporary files created
via `jj describe` helps to ensure that text editors can recognize the
filetype and alter settings accordingly. This will open the door for
an improved user experience, and allow for setting things like the
appropriate text-width/rulers, syntax highlighting of the diff summary
(see Git's commit tree-sitter grammer [1]), easy toggling of the `JJ:`
comment lines, etc.
I examined the behavior of filetype detection across a number of
common text editors, and the most universally-support mechanism was
to have a unique extension that does not include any periods. Meaning
that namespacing via something like `.jj.txt` instead, won't always be
detected due to inconsistent matching prioritization across editors.
It also makes sense to assume that we may want other Jujutsu-specific
filetypes in the future.
The filename prefix has also been switched to be `editor-` for clarity,
as well as to ease matching a glob-pattern if we ever need to garbage
collect leftover tempfiles. This structure is similar to what Mercurial
and Sapling do as well.

This is a convenience optimization to improve the default user
experience, since `jj log` is a frequently run command. Accessing the
help information explicitly still follows normal CLI conventions, and
instructions are displayed appropriately if the user happens to make a
mistake. Discoverability should not be adversely harmed.
Note that this behavior mirrors what Sapling does [2], where `sl` will
display the smartlog by default.

I wasn't quite happy with `jj support` but I couldn't think of
anything better when I moved the commands from `jj debug` in
e2b4d7058d. Thanks to @ilyagr for suggesting `jj util`.
The `heads()` revset function with one argument is the counterpart to
`roots()`. Without arguments, it returns the visible heads in the
repo, i.e. `heads(all())`. The two use cases are quite different, and
I think it would be good to clarify that the no-arg form returns the
visible heads, so let's split that out to a new `visible_heads()`
function.
This serves the role of limit() in Mercurial. Since revsets in JJ is
(conceptually) an unordered set, a "limit" predicate should define its
ordering criteria. That's why the added predicate is named as "latest".
Closes#1110
I think requests to reset the author came up twice in the last week,
so let's just add support for it. I copied git's behavior of resetting
the name, email, and timestamp. The flag name is also from git.
We need 1.64 to bump `clap` to `4.1`. We don't really need to upgrade
to that, but being on an older version causes minor confusions like
#1393. Rust 1.64 is very close to 6 months old at this point.
The `jj debug` commands are hidden from help and are described as
"Low-level commands not intended for users", but e.g. `jj debug
completion` is intended for users, and should be visible in the help
output.
By using one letter for the path type before and one letter for path
type after, we can encode much more information than just the current
'M'/'A'/'R'. In particular, we can indicate new and resolved
conflicts. The color still encodes the same information as before. The
output looks a bit weird after many years of using `hg status`. It's a
bit more similar to the `git status -s` format with one letter for the
index and one with the working copy. Will we get used to it and find
it useful?
@joyously found `o` confusing because it's a valid change id prefix. I
don't have much preference, but `●` seems fine. The "ascii",
"ascii-large", and "legacy" graph styles still use "o".
I didn't change `@` since it seems useful to have that match the
symbol used on the CLI. I don't think we want to have users do
something like `jj co ◎-`.
Unlike Mercurial, this isn't a template keyword/function, but a config knob.
Exposing graph_width to templater wouldn't be easy, and I don't think it's
better to handle terminal wrapping in template.
I'm not sure if patch content should be wrapped, so this option only applies
to the template output for now.
Closes#1043
This eliminates ambiguous parsing between "func()" and "expr ()".
I chose "++" as template concatenation operator in case we want to add
bit-wise negate operator. It's also easier to find/replace than "~".
