One less CLI revset helper. It might look odd that "jj rebase" says "Merge
failed" whereas "jj new" doesn't, but that depends on where the BackendError
is detected.
Commands like `new`, `duplicate`, and `abandon` can take multiple revset
arguments which results in their collective union. They take the revisions
directly as arguments. But for consistency with many other commands, they can
also take the `-r` argument, which is a no-op. However, due to the flag being
specified as a `bool`, the `-r` option can only be specified once, so e.g.
`abandon -r x -r y` often fails. I normally use `-r` for consistency and muscle
memory, so this bites me often.
Instead, use `clap::ArgAction::Count` in order to allow `-r` to be specified
multiple times. It remains unused, of course.
With this change, all the following invocations are equivalent. Before this
change, the second example would fail due to giving `-r` multiple times.
jj abandon x y
jj abandon -r x -r y
jj abandon -r 'x | y'
Note: `jj new` already supported this exact case actually, but it used an
awkward trick where it used `.overrides_with()` in order to override *itself* so
it could be specified multiple times. I believe this is a bit clearer.

This makes the summary line more informative. Even though it just duplicates
the message printed later, I think it's easier to follow.
This patch also adjusts some RevsetParseError messages because it seemed
redundant to repeat "revset function", "argument", etc.
Because the CLI error handler now prints error sources in multi-line format,
it doesn't make much sense to render Revset/TemplateParseError differently.
This patch also fixes the source() of the SyntaxError kind. It should be
self.pest_error.source() (= None), not self.pest_error.
Highlighting "{n}: " will help to follow error sources containing multi-line
messages. I'm going to make revset/template alias errors be formatted as plain
error chain.
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.
The lowercase "warning: " is unified to "Warning: " as it is the jj's
convention afaik.
The _default() suffix could be dropped from these methods, but it's probably
better to break the existing codebase for the moment. Otherwise, the caller
might do writeln!(ui.warning(), "Warning: ..").
The existing .hint() method is renamed to .hint_no_heading() to clarify that
it's not the default choice to print a hint. I'll add .hint_default() later,
which will be the shorthand for .hint_with_heading("Hint: ").
This fixes --change/--branch conflicts by making --change precede --branch. I
don't think this is the most obvious behavior, but it's the easiest workaround.
It could be moved before set_local_branch_target() to not update the local
branch, but it seemed weird that --change is silently ignored. This
inconsistency will be addressed later.
I'm going to reorganize CommandError as (kind, err, hints) tuple so that we
can add_hint() to the constructed error object.
Some config error messages are slightly adjusted because the inner error is
now printed in separate line.
As requested in #1471, I added a new flag for `jj branch list` to only show branches that are conflicted.
Adds a unit test to check for listing only conflicted branches and regenerates the cli output to incorporate the new flag.
Closes#1471

Apart from (IMO) looking nicer, this will also sidestep the potential problem
that if the file contains actual jj conflict markers (`>>>>>>>` in the beginning
of a line, for example), jj would currently have trouble materializing and
subsequently parsing conflicts in the file if it actually became conflicted.
I'll demo this bug in either this or a subsequent PR. It's the kind of bug that
sounds serious in theory but might never cause a problem in practice.
After this PR, only `docs/tutorial.md` has a conflict marker that's not indented.
There's only one there, so hopefully it won't be too much of a pain to deal with.
I also indented other strings in `test_conflicts.rs`. IMO, this looks nice and
more consistent with the `insta::assert_snapshot` output. I didn't spend the
time to do the same for `test_resolve_command`.
As discussed in #2900, the milliseconds are rarely useful, and it can
be confusing with different timezones because it makes harder to
compare timestamps.
I added an environment variable to control the timestamp in a
cross-platform way. I didn't document because it exists only for tests
(like `JJ_RANDOMNESS_SEED`).
Closes#2900
"-r REVISIONS" here specifies the search space of the branches to push, and
warned if no branches are found in that space. I don't think an empty set
should be an error, but a warning for consistency. The warning message will be
improved by the subsequent patches.
This command belongs to the same category as "duplicate".
We might want a plural version of resolve_revset(), but I'm not sure whether
it should return Vec<Commit> or Revset. Let's revisit it later when we get
more callers.
There's a subtle behavior change that an empty revset is no longer rejected
individually, but I think that's good for "jj duplicate".
cmd_duplicate() was the last caller of index.topo_order().
When an operation is missing and we recover the workspace, we create a
new working-copy commit on top of the desired working-copy commit (per
the available head operation). We then reset the working copy to an
empty tree because it shouldn't really matter much which commit we
reset to. However, when the workspace is sparse, it does matter, as
the test case from the previous patch shows. This patch fixes it by
replacing the `reset_to_empty()` method by a new `recover(&Commit)`,
which effectively resets to the empty tree and then resets to the
commit. That way, any subsequent snapshotting will result keep the
paths from that tree for paths outside the sparse patterns.
As shown by the updated test case, when we recover from a working copy
pointing to a lost operation, the new working-copy commit after
snapshotting will have lost any files outside the sparse patterns.
The original plan was to extend the globals table to implement "revset(expr)".
I'm not sure if that's more discoverable than "self.contained_in(revset_expr)"
method, but we can decide that later. Anyways, this patch adds typo suggestion
for global functions.
