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.
@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
When we materialize modify/delete conflicts, we currently don't
include any context lines. That's because modify/delete conflicts have
only two sides, so there's no common base to compare to. Hunks that
are unchanged on the "modify" side are therefore not considered
conflicting, and since they they don't contribute new changes, they're
simply skipped (here:
3dfedf5814/lib/src/files.rs (L228-L230)).
It seems more useful to instead pretend that the missing side is an
empty file. That way we'll get a conflict in the entire file.
We can still decide later to make e.g. `jj resolve` prompt the user on
modify/delete conflicts just like `hg resolve` does (or maybe it
actually happens earlier there, I don't remember).
Closes#1244.
I think the intent of '- 1' here is the separator length, which was
originally ':'. Alternatively, we can ensure that prefix + remainder is
always 12 chars.
Since CR+LF vs LF things shouldn't matter in commit description, it's probably
better to normalize newline characters.
In Mercurial, ui.edit() and changelog.stripdesc() handle line normalization,
and trailing newlines are stripped. In Git, cleanup_message() handles that,
and the last newline is added after stripping trailing newlines.
Otherwise the description set by -m would differ from the one set by editor.
This fixes test_describe() which says "make no changes", but previously "\n"
would be added by the second "jj describe".
As you can see, almost all hashes change in CLI tests. This means in-flight
PRs will need to be rebased to update insta snapshots.
Description text could be normalized by CommitBuilder, but the caller would
have to normalize it beforehand to compare with the current description, so
we would need an explicit function anyway. Another idea is to add a newtype
that represents a normalized description, and make CommitBuilder require it.
Commit::description() will return &Description in place of &str to ensure
that commit.description() == raw_str wouldn't compile.
Git CLI provides --cleanup=<mode> option to switch normalization rules, but
I don't think we'll need such feature.
The author timestamp is rarely useful (in my experience). The
committer timestamp, on the other hand, can be useful for
understanding when a change was most recently modified. IIRC, I
originally picked the author timestamp to match the email (which is
the author's), but it's probably not confusing to use the author email
and the committer timestamp. I suspect few users will even reflect on
it.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).

We have talked about showing the commit ID only for divergent changes
because it's generally easier to work with the change ID, and it's
less likely to result in a divergent change. However, it's useful to
have the commit ID available for pasting into e.g. a commit message or
the GitHub UI. To try to steer users towards using the change ID, this
commit moves the commit ID off to the right in the log output.
I put it just after the "divergent" field, because that makes it close
to how I imagine it would look if we decided to hide the commit ID
except for divergent changes. I was thinking that could be rendered as
"divergent (abc123)". So if we add config to hide the commit ID, then
it would be rendered almost the same for divergent commits (just with
the added parentheses). It would also make sense to replace the
"divergent" field by a question mark on the change ID, since change
IDs basically behave like branches. If we do that, then the placement
of the commit ID I picked in this commit does not make sense.
Given how easy this was, I can't believe I didn't make the change
sooner.
I haven't updated the screenshots in the readme because I plan to make
some further changes to the default template. I'll update them after
those changes.
I feel the original -------/+++++++ pair is slightly confusing because
each half can be a separator by itself. I don't know what character other
than '-'/'+' is preferred, but let's pick '%' (for "mod") per @martinvonz
suggestion.
In 8ae9540f2c, I made `jj move/squash/unsquash` not abandon the
working copy if it became empty because that would lose any
description associated with it. It turned out that the new behavior
was also confusing because it made it unclear if the working-copy
commit was actually abandoned. Let's roll back that change and instead
ask the user for a combined description when both the source and
destination commits have non-empty descriptions. Not discarding a
non-empty description seems like a good improvement regardless of the
behavior related to working-copy commits. It's also how `hg fold`
behaves (though hg doesn't allow the description to be empty).
This patch adds `jj obslog -p` for including the diff compared to the
predecessor (the first predecessor if there are several). If the
predecessor's parents are different, then we create a temporary tree
by rebasing the predecessor to have the same parents and we use the
result as base for the diff. That way, we avoid polluting the diff
with the changes caused by the rebase. (I don't think we currently
have any commands that can change both parents and content, so the
diff should always be empty for rewrites caused by a rebase.)
Working on this also reminded me that it'll be really nice when we
replace `jj obslog` by something based on the operation log - I really
miss seeing information about the operation in the output (like `hg
obslog` gets from its obsmarkers).
