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 "~".
Since there's no easy API to snapshot the stale working copy without releasing
the lock, we have to compare the tree ids after reacquiring the lock. We could
instead manually snapshot and rebase the working-copy commit, but that would
require more copy-paste codes.
Closes#1310
The outermost "op-log" label isn't moved to the default template. I think
it belongs to the command's formatter rather than the template.
Old bikeshedding items:
- "current_head", "is_head", or "is_head_op"
=> renamed to "current_operation"
- "templates.op-log" vs "templates.op_log" (the whole template is labeled
as "op-log")
=> renamed to "op_log"
- "template-aliases.'format_operation_duration(time_range)'"
=> renamed to 'format_time_range(time_range)'
We write conflict to the working copy by materializing them as
conflict markers in a file. When the file has been modified (or just
the mtime has changed), we parse the markers to reconstruct the
conflict. For example, let's say we see this conflict marker:
```
<<<<<<<
+++++++
b
%%%%%%%
-a
+c
>>>>>>>
```
Then we will create a hunk with ["a"] as removed and ["b", "c"] as
added.
Now, since commit b84be06c08, when we materialize conflicts, we
minimize the diff part of the marker (the `%%%%%%%` part). The problem
is that that minimization may result in a different order of the
positive conflict terms. That's particularly bad because we do the
minimization per hunk, so we can end up reconstructing an input that
never existed.
This commit fixes the bug by only considering the next add and the one
after that, and emitting either only the first with `%%%%%%%`, or both
of them, with the first one in `++++++++` and the second one in
`%%%%%%%`.
Note that the recent fix to add context to modify/delete conflicts
means that when we parse modified such conflicts, we'll always
consider them resolved, since the expected adds/removes we pass will
not match what's actually in the file. That doesn't seem so bad, and
it's not obvious what the fix should be, so I'll leave that for later.
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.
It's been about 10 weeks and 730 commits since 0.6.0, compared to
about 7 weeks and 350 commits between 0.5.0 and 0.6.0, so it's time
for a new release. There's been significant user-visible changes and
code-quality improvements. Thanks, everyone!
Supported values are,
- `none` for no author information,
- `full` for both the name and email,
- `name` for just the name,
- `username` for username part of the email,
- (default) `email` (or any other gibberish for that matter) for the full email.
I felt that the config is too narrow to have it's own top-level [diff]
section, and I couldn't think of another good place to have it. I'm
happy to hear other suggestions.
For stock merge-tools, having name -> args indirection makes sense. For
user-specific settings, it's simpler to set command name and arguments
together.
It might be a bit odd that "name with whitespace" can be parsed differently
depending on the existence of merge-tools."name with whitespace".
We have moved from saying "committing the working copy" towards saying
"snapshotting the working copy". More importantly, the option also
means that we don't update the working copy at the end. I went with
the `--ignore-working-copy` name suggested by Ilya. I also updated the
documentation of the option.
This allows us to use "if(description,)" to test empty description. And
I think this change is unavoidable if we want to add support for commit
template.
Git's HEAD ref is similar to other refs and can logically have
conflicts just like the other refs in `git_refs`. As with the other
refs, it can happen if you run concurrent commands importing two
different updates from Git. So let's treat `git_head` the same as
`git_refs` by making it an `Option<RefTarget>`.
I think of it more as style than a format, so using `style` in the
config key makes sense to me.
I didn't bother making upgrades easy by supporting the old name since
this was just released and only a few developers probably have it set.
The name of the [alias] section is inconsistent with other
table-valued sections ([revset-aliases], [colors], [merge-tools]), so
let's rename it. For comparison, `Cargo.toml` also uses plural names
(e.g. `[dependencies]`).
This is an example of labeled output of structured value types. I think
"{name} <{email}>" is a good default formatting, but I should note that
the signature also contains timestamp field.
This makes us sanitize ANSI escape bytes in the output if it goes to
the terminal, even when it's not colored (by us), such as when using
`--color=never`. That means that e.g. `jj cat
tests/test_commit_template.rs` will not be colored, but `jj cat
tests/test_commit_template.rs | cat` will be. Sanitizing output sent
to the terminal might help reduce some security threats based on
hiding content by using ANSI escapes.
We could add a config option for sanitizing the output, but I'm not
sure it'll be useful.
`jj cat` better matches `hg cat` and, of course, `cat`. I apparently
called it `jj print` when I added it in 7a013a59ae because I haven't
found `hg cat` useful for actually concatenating files. That's still
true, and I don't know if we will ever bother to teach `jj cat` to
actually concatenate files, but I think the familiarity of `cat` is
more important.
For reference, Git calls it `git show <rev>:<file>`.
I kept `print` as an alias and added a test for it. I also documented
the test better.
By the way, I've considered adding a command for writing from stdin
directly to a specific commit. If we ever do, it might make sense to
call that command `write` (e.g. `echo foo | jj write -r @-
README.md`). Then it would make sense to add `read` as an alias to
`cat`. I'm not sure that's a good idea, but let's leave that for later
anyway.
The `indexmap` crate is used to make `duplicate`'s output have a sane order,
making it easier to test.
It's also used later to remove duplicate revisions in the `abandon` command.
Fixes https://github.com/martinvonz/jj/issues/1050
Thanks to Martin for suggesting the exact fix.
The tests go into the new tests/test_duplicate_command.rs, which will be
expanded shortly with other tests depending on this bugfix.
The `git.fetch` and `git.push` keys can be used in the configuration file
for the default to use in `jj git fetch` and `jj git push` operations.
By defaut, "origin" is used in both cases.
You may use "abc\\" in .gitignore to ignore a file named "abc\". In this
case, removing training spaces on "abc\\ " must result in "abc\\" as the
trailing space is not escaped, the preceeding backslash being part of
the previous "\\" escaping sequence.
- branches has the signature branches([needle]), meaning the needle is optional (branches() is equivalent to branches("")) and it matches all branches whose name contains needle as a substring
- remote_branches has the signature remote_branches([branch_needle[, remote_needle]]), meaning it can be called with no arguments, or one argument (in which case, it's similar to branches), or two arguments where the first argument matches branch names and the second argument matches remote names (similar to branches, remote_branches(), remote_branches("") and remote_branches("", "") are all equivalent)
If a workspace path is explicitly specified, it must point to the exact
workspace directory. This is the same behavior as 'hg -R'. OTOH, 'git -C'
is the option to chdir, so it makes sense to search .git from that directory.
This also fixes 'jj -R ../..' which would previously look up '../..', '..',
'.', ...
Since per-repo config may contain CLI settings, it must be visible to CLI.
Therefore, UserSettings::with_repo() -> RepoSettings isn't used, and its
implementation is nullified by this commit.
#616
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.
"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.
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.
