Actually, it's easier to support these infix ops than erroring out, but I
don't want to make revset syntax more cryptic. "x- y" can't be handled by
this rule because "x-" is parsed as a parents expression.
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.
I ran an upgraded Clippy on the codebase. All the changes seem to be
about using variables directly in format strings instead of passing
them as separate arguments.
"jj log -p --summary" now shows summary and color-words diff, like
"hg log -p --stat".
Handling of "-p" is tricky. I first considered "-p" would turn on the default
diff output, but I found it would be confusing if "jj log -p --git" showed
both color-words and git diffs. So the default format is inserted only if
no --git nor --color-words is explicitly specified.
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.
Clap bails parsing when an "error" is encountered, e.g. a subcommand is missing,
"--help" is passed, or the "help" subcommand is invoked. This means that the
current approach of parsing args does not handle flags like `--no-pager` or
`--color` when an error is encountered.
Fix this by separating early args into their own struct and preprocessing them
using `ignore_errors` (per https://github.com/clap-rs/clap/issues/1880).
The early args are in a new `EarlyArgs` struct because of a known bug where
`ignore_errors` causes default values not to be respected
(https://github.com/clap-rs/clap/issues/4391 specifically calls out bool, but
strings may also be ignored), so when `ignore_errors` is given, the default
values will be missing and parsing will fail unless the right arg types are used
(e.g`. Option`). By parsing only early args (using the new struct) we only need
to adjust `no_pager`, instead of adjusting all args with a default value.
The number of lines in the diff output is unchanged.
This makes diffs a little more readable when the "..." would otherwise hide a
single line of code that helps in understanding the surrounding context lines.
This change mostly rearranges the loop that consumes the diff lines, so it can
buffer up to num_context_lines*2+1 lines instead of just num_context_lines.
There's a bit of extra code to handle times when a "..." replaces the last line
of a diff.
Note that `jj diff --git` is unchanged, and will still output `@@` lines that
replace a single line of context.
This fixes the bug described in the previous commit.
Because we now print the message about failed exports also while
snapshotting, we may end up reporting it twice on one command. I'm not
sure it's worth worrying about that. We can deal with that later if it
turns out to be a common complaint.
If a branch points to the working-copy commit, it will automatically
get updated when the working copy is snapshotted. However, it turns
out that we don't automatically export the change to Git when running
in a colocated working copy (nor in a non-colocated working copy, but
that shouldn't be surprising). The change will not get exported until
a non-snapshot operation runs. We noticed this bug in @hooper's repo
today.
Unfortunately, config::Value is lax and '[7]' could be parsed as '["7"]'.
I don't like it, but I think that's actually better for consistency as we
use config.get_string() in various places.
When a workspace's working-copy commit is updated from another
workspace, the workspace becomes "stale". That means that the working
copy on disk doesn't represent the commit that the repo's view says it
should. In this state, we currently automatically it to the desired
commit next time the user runs any command in the workspace. That can
be undesirable e.g. if the user had a slow build or test run started
in the working copy. It can also be surprising that a checkout happens
when the user ran a seemingly readonly command like `jj status`.
This patch makes most commands instead error out if the working copy
is stale, and adds a `jj workspace update-stale` to update it. The
user can still run commands with `--no-commit-working-copy` in this
state (doing e.g. `jj --no-commit-working-copy rebase -r @ -d @--` is
another way of getting into the stale-working-copy state, by the way).
Also allows several paths to be specified. By default, `jj resolve`
will find the first conflict that matches provided paths (if any)
and try to resolve it.
It seems like I forgot to update the `jj status` output when I decided
(years ago?) that the changes in a commit should always be compared to
the auto-merged parents. I was very confused before I realized that
`jj status` was showing the diff summary against the first parent. I
suppose the fact that `jj status` lists only one parent should have
been a hint. Thanks to ilyagr@ for finding this odd behavior. This
patch fixes it by making the command list all parents, and changes the
diff summary to be against the auto-merged parents.
If this new option is not specified, we start with empty output
file and trust the merge tool did a complete merge no matter
what the file contains.
Includes tests.
This command uses an external merge tool to resolve conflicts
simple enough that they can be resolved with a 3-way merge.
This commit provides a very basic version of `jj resolve` that
is hardcoded to use vimdiff.
This also slightly changes the errors of the Diff Editor, so that
both the diff editor and `jj resolve can share an error type.
Because a unary negation node '~y' is more primitive than the corresponding
difference node 'x~y', '~y' is easier to deal with while rewriting the tree.
That's the main reason to add RevsetExpression::NotIn node.
As we have a NotIn node, it makes sense to add an operator for that. This
patch reuses '~' token, which I feel intuitive since the other set operators
looks like bitwise ops. Another option is '!'.
The unary '~' operator has the highest precedence among the set operators,
but they are lower than the ranges. This might be counter intuitive, but
useful because a prefix range ':x' can be negated without parens.
Maybe we can remove the redundant infix operator 'x ~ y', but it isn't
decided yet.
