Add a parents() method for `Operation` template objects, copied from the
implementation for `Commit`s.
The test case added in test_operations.rs was heavily inspired by
test_commit_templates.rs:test_log_parents().
Fixes#6979
Since the goal of this pseudo type is to get a String value, it can be called a
ToString or Stringify. I chose the latter because Stringify sounds similar to
Serialize (verb), and I don't want to rename the internal functions to
.try_into_to_string().
https://github.com/jj-vcs/jj/pull/6840#discussion_r2173076763
This was discussed in #3219 and #3262, and apparently, people don't agree
whether we should implement machine-readable formatting by using templater.
However, there are recurring requests about JSON output, and "jj api" is still
vaporware. So I think it's good to add some support for JSON output.
I'm not going to add syntax to build custom JSON object/list for now. Instead,
property types such as Commit will implement fixed serialization output. The
user might have to write ad-hoc JSON constructs to concatenate the default JSON
output and their custom JSON fields.
We'll need a documentation about which types are serializable. I think this can
be added later when more types get serialization support.
This is the last part of the series 02722eae54 "view: port bookmark/tag name
types to RefName/RemoteName." Templater doesn't use these name types internally
because we wouldn't gain much type safety in template language.
The return type of .remote() is changed to Option<RefSymbol>. An empty symbol is
rendered with quotes, so it would be weird if local_bookmark.remote() returned
an empty RefSymbol.
I'm going to add RefSymbol(String) type to format bookmark/remote name in revset
syntax. Since an empty symbol will be rendered differently from an empty string,
bookmark.remote() -> String will be changed to -> Option<RefSymbol>. Then, we'll
need to add support for comparison between optional and non-optional values.
In template language, method call on None produces an error. If we followed this
rule, comparison would have to be expressed as `opt && opt == lit`. I feel this
would be too verbose, and wouldn't help eliminate user error caused by
unintended comparison between Option<T> and T anyway. So this patch implements
comparison by lifting T to Option<T> implicitly.
In docs/templates.md, the Commit type and Operation type looked like:
`method() -> ReturnType`
rather than everything else, which looks like:
`.method() -> ReturnType`
This commit changes the Commit and Operation types to look more like the
rest of the documentation.
I'm thinking of adding RefName(str) and RemoteName(str) newtypes, and the
templater type name would conflict with that. Since the templater RefName type
is basically a (name, target) pair, I think it should be called a "Ref", and I
added "Commit" prefix for disambiguation.
This isn't a breaking change since template type names only appear in docs and
error messages.
Allows:
* self.commit()
* self.line_number()
* self.first_line_in_hunk()
Certain pagers (like `delta`), when used for `git blame`, only show the
commit information for the first line in a hunk. This would be a nice
addition to `jj file annotate`.
`jj file annotate` already uses a template to control the rendering of
commit information --- `templates.annotate_commit_summary`. Instead of
a custom CLI flag, the tools necessary to do this should be available in
the template language.
If `1 % 2` or `1.is_even()` was available in the template language, this
would also allow alternating colors (using `raw_escape_sequence`).
Example:
```toml
[templates]
# only show commit info for the first line of each hunk
annotate_commit_summary = '''
if(first_line_in_hunk,
show_commit_info(commit),
pad_end(20, " "),
)
'''
```
If an ellipsis arg is given to the truncate_* template functions, append (or
prepend) the ellipsis when the template content is truncated to fit the maximum
width.
Fixes#5085.
I originally considered adding `stats() -> DiffStats` which returns an
unprintable object, with deprecation of `.stat(width)` in favor of
`.stats().<method_to_render>(width)`. However, I couldn't find a good name for
the rendering function. This patch instead made the width parameter optional. I
think that's good because template language doesn't have to be overly strict.
Closes#4154
Add a new pad_center function that centers content within a minimum
width. If an odd number of fill characters is required, the trailing
fill will be one character longer than the leading fill.
Fixes#5066.
This can be used in order to count the number of added files by
diff.files().filter(..).len(), for example. If we add more advanced fileset
predicates, it can also be expressed as diff("added()").files().len(). The
latter would be cheaper to compute.
For #4154, I'll probably add DiffStats template type. It might be doable by
extending diff.files() method, but I don't think it's good idea to write stats
calculation logic in template language.
Closes#5272
I'm going to add "file list" template, and I think it's better to provide a file
path as "path", not "self". This patch also adds some tree value properties
which seemed useful.
Tests will be added later.
This will be used in "file list" template. Option<RepoPath> type isn't
needed for that, but I think it'll appear somewhere in custom diff template.
The path.parent() method is added mainly for testing Option<RepoPath>.
Tests will be added later.
Disclaimer: this is the work of @necauqua and @julienvincent (see
#3141). I simply materialized the changes by rebasing them on latest
`main` and making the necessary adjustments to pass CI.

I had to fix an issue in `TestSignatureBackend::sign()`.
The following test was failing:

Print debugging revealed that the signature was bad, because of a
missing trailing `\n` in `TestSignatureBackend::sign()`.

The `Signature.email()` method is also updated to return the new Email
type. The `Signature.username()` method is deprecated for
`Signature.email().local()`.
As I said in the preceding patch, I settled on separate pad/truncate functions
instead of a function taking multiple optional parameters. It's less efficient
to process truncation and padding independently, but I don't think that would
matter.
The order of arguments follows the current f(..., content) convention. We can
also add a method syntax, but I'm not sure if it's useful. In order to call a
method of Template type, we'll need to coerce printable object to Template:
concat(author.email()).truncate_end(10).pad_end(10)
^^^^^^
String -> Template
FWIW, String type could provide more efficient truncate/pad methods.
Closes#3183
This allows for more fine-grained control of timestamp formatting, for
example:
```
[template-aliases]
'format_timestamp(timestamp)' = '''
if(timestamp.before("1 week ago"),
timestamp.format("%b %d %Y %H:%M"),
timestamp.ago()
)
'''
```
Closes#3782.
This adds `raw_escape_sequence(...)` support for things that use
FormatRecorder like wrapped text / `fill(...)` / `indent(...)`.
Change-Id: Id00000004248b10feb2acd54d90115b783fac0ff
Templates can be formatted (using labels) and are usually sanitized
(unless for plain text output).
`raw_escape_sequence(content)` bypasses both.
```toml
'hyperlink(url, text)' = '''
raw_escape_sequence("\e]8;;" ++ url ++ "\e\\") ++
text ++
raw_escape_sequence("\e]8;;\e\\")
'''
```
In this example, `raw_escape_sequence` not only outputs the intended
escape codes, it also strips away any escape codes that might otherwise
be part of the `url` (from any labels attached to the `url` content).
Not all formatters (namely FormatRecorder) are supported yet.
Change-Id: Id00000004492dbf39e50f3b7090706839d1d8d45
One particular use case for these is escape sequences -- and to that
end, I'm also adding `\e` as a shorthand for `\x1b`.
