This allows us to insert a separator between non-empty template fragments.
Since FormattablePropertyTemplate::has_content() needs to extract
a TemplateProperty, using this function means the property function will
be evaluated twice, one by .has_content() and later by .format(). The cost
is basically the same as 'if(prop, " " prop)'.
I believe this isn't a good abstraction, but I need to add one more variant
for "at least n arguments" error. A stringified count like "2 to 3" could be
embedded in an error variant, but I don't think it's good idea to build error
message in that way.
The way I added support for processing custom global arguments - by
using the existing `dispatch_fn` - meant that it wouldn't be run if
`CliRunner::add_global_args()` was called before
`CliRunner::add_subcommand()` and the custom subcommand wasn't
run. That's clearly not what I intended. This commit fixes that by
adding a separate list of functions for processing global args.
It's easier to mutate `self` than to create a new instance. It does
increase the risk of forgetting to update a field when adding a new
field or a new function, so maybe that's why @yuja did it this way?
Maybe I didn't make this change before because the closure needs to capture
WorkspaceId by value. Since the inlined version looks pretty simple, let's
go forward to do that.
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.
Even though the template syntax is experimental, panicking parser makes
it difficult to write tests. So let's add minimal error handling. The error
types are basically copied from the revset module.
I made write_commit_summary() fall back to the default template if user
template had syntax error. It should be better than reporting parse error
after e.g. "jj abandon" finished successfully.
Accept an --include-defaults arg to enable including those.
Listing a nonexistent name is no longer an error, but does output a
warning to stderr when no config entries match to explain why there's no
other output.
I have no idea whether or not any template expressions are intentionally
allowed as a label, but it makes sense to write something like
'label("phase-" phase, ...)' (if we had a phase keyword.) So I decided to
add .into_plain_text() instead of stricter .try_into_string().
Perhaps, non-trivial keywords can be extracted to free functions, and both
parsing and property functions can be eventually moved to a commit templater
module?
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.
This allows us to merge parse_boolean_commit_property() into
parse_commit_term(). We'll probably need similar type coercion methods
for the other basic types.
I considered adding something like Property::Template(), which could be
reused for map operation (e.g. 'revset().map(commit_id).join(" ")'.)
However, a mapped commit template would be different from the top-level
commit template regarding the lifetime of the context.
"Expression::<Commit>::Template()" takes "for<'b> &'b Commit" as an argument,
whereas a mapped template property would capture Commit object somewhere.
I keep calling it `underline` by mistake, so that probably means that
it's a more natural name for it. We haven't made a release of it yet,
so I didn't mention it in the changelog.
I didn't update all variables to also use `underline`, because I felt
that `underlined` was usually more natural there, plus crossterm calls
it `Attribute::Underlined`.
Many template keywords and methods are one liners, and I think that's actually
good because writing tests for templater would be more involved than for pure
functions.
This patch introduces a wrapper for such one-line functions, and migrates
method parser to that. Some of the commit keyword structs can also be ported
to this wrapper.
This refactors the unique prefix functionality and extracts a function
that will be reused by the styled prefix highlighting.
This also includes a minor change in functionality: if the unique prefix
of an id does not fit into the space provided, it is still printed.
Currently, this would happen if the prefix is more than 12 characters
long, which takes a huge repository. However, I'm hoping that in the
future we'll make this number customizeable.
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>`.
