Since we now have the template alias, it's easy to migrate the config value
programatically. However, there are a couple of minor behavior changes:
a. default description won't be used if user customized the
draft_commit_description template.
b. default description won't be inserted if trailer is added
For (a), I assumed user would inline the default description in the draft
template if they customized the template. (b) should be okay because the
trailers template is a new feature.
Since 7618b52b "cli: consider 'JJ:' lines as comments also when not followed by
space", lines starting with "JJ:" (without space) are also ignored. We can
simply add "JJ:" prefix to empty intro/instruction lines.
Closes#5484
I'm going to add "[EOF]" marker to test that command output is terminated by
newline char. This patch ensures that callers who expect a raw output string
would never be affected by any normalization passes.
Some common normalization functions are extracted as CommandOutputString
methods.
This patch doesn't fix DiffEditor::edit() API, which is fundamentally broken
if matcher argument is specified. I'm not sure if the builtin behavior is
correct or not. Suppose we add "jj diffedit FILESETS..", it would probably make
sense to leave unmatched paths unmodified because it is the command to edit the
destination (or right) tree. This is the edit_diff_external() behavior.
Fixes#5252
We currently ignore lines prefixed with "JJ: " (including the space)
in commit messages and in the list of sparse paths from `jj sparse
edit`. I think I included the trailing space in the prefix simply
because that's how we render comments line we insert before we ask the
user to edit the file. However, as #5004 says, Git doesn't require a
space after their "#" prefix. Neither does Mercurial after their "HG:"
prefix. So let's follow their lead and not require the trailing
space. Seems useful especially for people who have their editor
configured to strip trailing spaces.
This implements a building block of "signed-off-by line" #1399 and "commit
--verbose" #1946. We'll probably need an easy way to customize the diff part,
but I'm not sure if it can be as simple as a template alias function. User
might want to embed diffs without "JJ: " prefixes?
Perhaps, we can deprecate "ui.default-description", but it's not addressed in
this patch. It could be replaced with "default_description" template alias,
but we might want to configure default per command. Suppose we add a default
"backout_description" template, it would have to be rendered against the
source commit, not the newly-created backout commit.
The template key is named as "draft_commit_description" because it is the
template to generate an editor template. "templates.commit_description_template"
sounds a bit odd.
There's one minor behavior change: the default description is now terminated
by "\n".
Closes#1354
`tx.format_commit_summary()` can be expensive because it needs to build
an IdPrefixContext now, so it's best to avoid formatting instruction
messages unless they are actually required.
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.
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.
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.
Renamed `description_template_for_commit` to
`description_template_for_describe` since it's only used in
`cmd_describe`.
Renamed `description_template_for_cmd_split` to
`description_template_for_commit` and modified to accomodate empty
`intro` argument.
Fixes#2439.
That is, jj will use ui.default_description as a starting point when
user is about to describe an empty change.
I think it might be confusing to do this with -m / --stdin (violates
WYSIWYG), so I'm only doing this when jj invokes an editor.
Also, this could evolve into a proper template in the future instead of
just plain text, to allow inheriting from parent change(s), for example.
Partially addresses #1354.
