I'm going to introduce two changes: 1. indent commit summary, 2. colorize
output. The former can be implemented without using the templater API, but the
latter can't.
IntoTemplate will be cleaned up later. Perhaps, the lifetime parameter can be
removed at this point, but I'm planning to remove the IntoTemplate trait at all.
The type parameter 'C' will be removed from the Template trait, making it
represent a printable type or compiled template.
TemplateRenderer now holds Box<dyn _> template because it's unlikely that the
inner template type can be statically determined.
This fixes --change/--branch conflicts by making --change precede --branch. I
don't think this is the most obvious behavior, but it's the easiest workaround.
It could be moved before set_local_branch_target() to not update the local
branch, but it seemed weird that --change is silently ignored. This
inconsistency will be addressed later.
This helps to implement CommandError::add_hint(). The inner errors could be
embedded in the enum as before, but they're mostly of the same type. And I think
it's okay to use downcast_ref() to deal with the clap::Error special case.
I'm going to reorganize CommandError as (kind, err, hints) tuple so that we
can add_hint() to the constructed error object.
Some config error messages are slightly adjusted because the inner error is
now printed in separate line.
I think Option<Commit> is the simplest encoding of the log node.
The behavior of an Option type is closer to nullable types rather than the
Option in Rust. I don't think we would want to write opt.map(|x| x.f()) or
opt.unwrap().f(). We can of course add opt?.f() syntax, but it will be a short
for "if(opt, opt.f())"?
Studies show that children raised in households that run `cargo update`
regularly report greater self-esteem, recompile more often, have better
dependency hygiene than their peers, and are less likely to hit dependency hell,
run into vulnerable outdated code, or go back to C++.

The latest version `0.61.1` was yanked, and there hasn't been an update yet.
This should unblock the CI system.

As requested in #1471, I added a new flag for `jj branch list` to only show branches that are conflicted.
Adds a unit test to check for listing only conflicted branches and regenerates the cli output to incorporate the new flag.
Closes#1471

These two are common when implementing methods. Fortunately, the
"return-position impl Trait in traits" feature is stabilized in Rust 1.75.0,
so we don't need another variant of TemplateFunction.
Apart from (IMO) looking nicer, this will also sidestep the potential problem
that if the file contains actual jj conflict markers (`>>>>>>>` in the beginning
of a line, for example), jj would currently have trouble materializing and
subsequently parsing conflicts in the file if it actually became conflicted.
I'll demo this bug in either this or a subsequent PR. It's the kind of bug that
sounds serious in theory but might never cause a problem in practice.
After this PR, only `docs/tutorial.md` has a conflict marker that's not indented.
There's only one there, so hopefully it won't be too much of a pain to deal with.
I also indented other strings in `test_conflicts.rs`. IMO, this looks nice and
more consistent with the `insta::assert_snapshot` output. I didn't spend the
time to do the same for `test_resolve_command`.
Now a compiled template doesn't have a static Context type internally. A
property is basically of "Fn() -> Result<O, _>" type, and a type-erased "self"
variable will be injected as needed.
Template<C> types will be refactored separately.
In short, this enables compilation of template of e.g. Vec<Commit> type by
using CommitTemplateLanguage.
A Template<C> was originally compiled for a specific type C, and invoked as
"Fn(&C) -> _". It was simple and intuitive, but we had to define the context
type C statically. Things got even worse by extensions support because we had
to provide object-safe hook point for each context type C.
This patch basically removes the Context type from compiled templates. The
"self" variable is injected through RefCell<Option<C>> placeholder. A compiled
template knows its "self" type, but the type can be decided per instance, not
per TemplateLanguage type. A drawback is that the "self" variable will have to
be cloned one more time.
The Template<C> abstraction no longer makes sense, and will be split to inner
Template<()> implementations (which usually represent printable types) and the
outer Template<C>.
The idea is basically the same as list.map(|x| ...) template. It compiles the
inner template with a placeholder variable of type 'C', and evaluate it for
each instance variable by injecting the variable through RefCell.
Because GenericTemplateLanguage doesn't support any global resources, it no
longer makes sense to pass the language instance around to 0-ary keyword
functions.
These .wrap_<type>() functions aren't supposed to capture resources from the
language instance. It was convenient that wrap_() could be called without fully
spelling the language type, but doing that would introduce lifetime issue in
later patches.
I added type alias L to several places because the language type is usually
called L in generic code.
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
`jj rebase -r C -d A; rebase -s B -d C` is missing the second jj.
Although it would be cool if jj had syntax to chain commands like this, so I could write a "swap" alias.
