Perhaps, the original intent was to abandon non-empty working-copy commit
assuming it was rewritten by git (therefore it should be superseded by the
current working-copy content.) However, there are other reasons that could
make the HEAD out of sync (including concurrent jj operations), and abandoning
non-empty commit can be a disaster. This patch turns it to safer side, and let
user abandon non-empty commit manually.
Fixes#3747
"config list NAME" argument is now parsed as TOML key, but it's still broken
since config.get() expects a query expression in different syntax.
The other config commands will be migrated later.
This revset correctly implements "reachability" from a set of source commits following both parent and child edges as far as they can go within a domain set. This type of 'bfs' query is currently impossible to express with existing revset functions.
This follows up on https://github.com/martinvonz/jj/pull/3459 and adds a
label to the closing delimeter of each conflict, e.g. "Conflict 1 of 3
ends".
I didn't initially put any label at the ending delimeter since the
starting delimeter is already marked with "Conflict 1 of 3". However,
I'm now realizing that when I resolve conflicts, I usually go from top
to bottom. The first thing I do is delete the starting conflict
delimeter. It is when I get to the *end* of the conflict that I wonder
whether there are any more conflicts left in the file.
This consolidates the type of substitution results. Before, symbol substitution
can return inner ExpressionKind internally, but function-parameter substitution
couldn't.
This should avoid regression caused by upcoming changes. An alias function
parameter will be wrapped with AliasExpanded, and type errors in it should
be reported with its alias expansion stack.
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.
When using `ui.color = "debug"`, changes in the output style
additionally include delimiters << and >>, as well as all active labels
at this point separated by ::. The output is otherwise unformatted and
the delimiters and labels inherit the style of the content they apply
to.
Not all "branch list --all-remotes" callers are replaced because I'm going to
make get_branch_output() suppress hints by default, and there should be tests
for the hints.
This also means "all:" is allowed in default revsets (such as "revsets.log"),
but that seems okay. In revset aliases, "all:" isn't allowed because aliases
may be expanded to sub-expression position.
Closes#3654
Perhaps, this can be used to generate parsable branches list.
The hint for deleted branches isn't migrated to the template. I'm thinking of
moving it out of the loop and printed once at the end. If we want to generate
a hint in template, we'll probably need local_ref.tracking_remote_refs(), etc.
that return a list of RefNames.
More tests will be added later as "branch list" templates.
In "log" template, we might want to see the number of "local" commits ahead
of any tracked remotes. It can be implemented later in a similar way (or as a
nested remote_refs list.)
For example,
```
<<<<<<< Conflict 1 of 3
+++++++ Contents of side #1
left 3.1
left 3.2
left 3.3
%%%%%%% Changes from base to side #2
-line 3
+right 3.1
>>>>>>>
```
or
```
<<<<<<< Conflict 1 of 1
%%%%%%% Changes from base to side #1
-line 3
+right 3.1
+++++++ Contents of side #2
left 3.1
left 3.2
left 3.3
>>>>>>>
```
Currently, there is no way to disable these, this is TODO for a future
PR. Other TODOs for future PRs: make these labels configurable. After
that, we could support a `diff3/git`-like conflict format as well, in
principle.
Counting conflicts helps with knowing whether you fixed all the
conflicts while you are in the editor.
While labeling "side #1", etc, does not tell you the commit id or
description as requested in #1176, I still think it's an improvement.
Most importantly, I hope this will make `jj`'s conflict format less
scary-looking for new users.
I've used this for a bit, and I like it. Without the labels, I would see
that the two conflicts have a different order of conflict markers, but I
wouldn't be able to remember what that means. For longer diffs, it can
be tricky for me to quickly tell that it's a diff as opposed to one of
the sides. This also creates some hope of being able to navigate a
conflict with more than 2 sides.
Another not-so-secret goal for this is explained in
https://github.com/martinvonz/jj/pull/3109#issuecomment-2014140627. The
idea is a little weird, but I *think* it could be helpful, and I'd like
to experiment with it.
I considered adding RefTarget template type, but some of the methods naturally
fit to RefName. For example, a conflicted branch name is decorated as "??", so
it makes sense to add branch.conflict() instead of branch.target().conflict().
I'm not pretty sure how many RefName methods we'll need to add to port the
current branch listing, but there will be .tracked(), .tracking_local_present(),
.ahead_by(), and .behind_by().
I'm going to add more detailed output there. This is a step towards "branch
list" template. "tag list -T" wouldn't be that useful, but it shares primitives
with "branch list -T".
The `move_commits` function accepts a set of target commits to shift to
a new location given by `new_parents` and `new_children`. The roots of
the target set will be reparented onto `new_parents`. `new_children`
will then be reparented onto the heads of the target set.
The commits will be rebased in reverse topological order based on the
new set of parents of each commit, which avoids the need for multiple
sets of rebase operations.
