This patch adds TreeDiff template type to host formatting options. The main
reason of this API design is that diff formats have various incompatible
parameters, so a single .diff(files, format[, options..]) method would become
messy pretty quickly. Another reason is that we can probably add custom
summary templating support as diff.files().map(|file| file.path()..).
RepoPathUiConverter is passed to templater explicitly because the one stored
in RevsetParseContext is behind Option<_>.
This not only makes the output easier to read, but also protects against
implementation detail changes in `write!` when used with a format
string (especially, how many times and with what strings it calls the
underlying writer).
I've run into change ID prefixes being 4-5 characters instead of the
usual 1-2 characters in commands like `jj duplicate` and `jj split`
fairly often, and it seems like this should resolve that.
It's common to create empty working-copy commits while using jj, and
currently the author timestamp for a commit is only set when it is first
created. If you create an empty commit, then don't work on a repo for a
few days, and then start working on a new feature without abandoning the
working-copy commit, the author timestamp will remain as the time the
commit was created rather than being updated to the time that work began
or finished.
This commit changes the behavior so that discardable commits (empty
commits with no description) by the current user have their author
timestamps reset when they are rewritten, meaning that the author
timestamp will become finalized whenever a commit is given a description
or becomes non-empty.
This simplifies the interface of helper functions. While revset doesn't have
top-level string pattern or integer literal, these parsing helpers could be
used to parse array subscript or n-th parent operator if any.
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.
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.)
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.
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
this greatly speeds up the time to run all tests, at the cost of slightly larger recompile times for individual tests.
this unfortunately adds the requirement that all tests are listed in `runner.rs` for the crate.
to avoid forgetting, i've added a new test that ensures the directory is in sync with the file.
## benchmarks
before this change, recompiling all tests took 32-50 seconds and running a single test took 3.5 seconds:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test test_working_copy'
Time (mean ± σ): 3.543 s ± 0.168 s [User: 2.597 s, System: 1.262 s]
Range (min … max): 3.400 s … 3.847 s 10 runs
```
after this change, recompiling all tests take 4 seconds:
```
; hyperfine 'touch lib/src/lib.rs ; cargo t --test runner --no-run'
Time (mean ± σ): 4.055 s ± 0.123 s [User: 3.591 s, System: 1.593 s]
Range (min … max): 3.804 s … 4.159 s 10 runs
```
and running a single test takes about the same:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test runner -- test_working_copy'
Time (mean ± σ): 4.129 s ± 0.120 s [User: 3.636 s, System: 1.593 s]
Range (min … max): 3.933 s … 4.346 s 10 runs
```
about 1.4 seconds of that is the time for the runner, of which .4 is the time for the linker. so
there may be room for further improving the times.
The formatting is closer to hg than git just because it's easier to
conditionalize the whole line per keyword. Our template language doesn't
have infix logical operators.
Unlike the other default templates, all remote branches are displayed because
it's "detailed" output.
Closes#2509
The problem is that the first non-working-copy commit moves the unborn current
branch to that commit, but jj doesn't "export" the moved branch. Therefore,
the next jj invocation notices the "external" ref change, which was actually
made by jj.
I'm not sure why we play nice by setting the "current" HEAD, but I *think* it's
okay to set the "new" HEAD and reset to the same commit to clear Git index.
With the idea that less severe placeholders (like description) could
(and should) explicitly "opt out".
(Both email and name placeholders will be red with this change.)
This patch also extracts format_detailed_signature() function to deduplicate
the "show" template bits.
The added placeholder templates aren't labeled as "empty". If needed, I think
the whole template can be labeled as "empty" (or "empty_commit") just like
"working_copy".
Closes#2112
Bright green really pops on my screen, and I don't think there is a reason
for the root commit to be attention-grabbing.
This follows up on https://github.com/martinvonz/jj/pull/2084.
I've extracted the `builtin_log_root` template for users to customize the
default templates without fully overriding them, for example I would remove
the change_id/commit_id for myself - and we discussed in Discord that leaving
those makes sense for the user to be reminded/teached that the root commit has
a change id made from z's.
