We are a little weird about which string escapes we support, and we don't
support raw strings. I thought this might be worth documenting.

Thanks to @lazywei for pointing out that `git pack-refs --all` is better, at
least on the first run. I haven't checked, but suspect, that because of the
number of `refs/jj` refs jj creates, it might always be better.
This is essentially a new version, which clarifies multiple statements about
`jj run`. Notably, it cleans up some mistakes which were overlooked or deemed
good enough in the Google Docs version.
This ticks another box in #1869.

https://github.com/martinvonz/jj/discussions/2230 indicates a lot of
interest in this, so we'd probably want to support this officially at
some point. Until then, document a script that has worked well-enough
for some of us.
I think the feature is requested by enough users that we should
include it by default, also for people who install from source (we
include it in the `packaging` feature already).
It increases the size of the binary from 16.5 MiB to 17.8 MiB. I
suspect we'd see some of that increase in size soon anyway, as I'm
probably going to use Tokio for making async backend requests.
Suppose "x::y" is the operator that defaults to "root()::visible_heads()"
respectively, "::" is identical to "all()". Since we've just changed the
behavior of "..y", ".." is now "root()..visible_heads()" meaning "~root()".
One action publishes the 'prerelease' version on every push
to `main`.
The other publishes a 'latest' version on every releasse.
I tested both of them, but not with branch protection rules.
I initially was thinking of using `mdbook`, which looks a little better, but I
think versioning the docs is important, and the features I want are pretty much
only supported by the Mkdocs' "Material" theme.
Mkdocs is written in Python. The prerequesites for building docs on your
machine should be to install Python and Poetry, everything else should be
installed automatically by Poetry. See the edits to `contributing.md` for more details.
This allows the tutorial to reference them and will make it
easier to have different instructions for different versions.
We can later restore some instructions to the README, but I
think this is important since the installation instructions
do change in important (even if slight) ways from time to
time.
`vimtabdiff` has a few potential advantages:
- It can be much more convenient for diffs with few files
- It can be easier to set up for some people (it is a Python script rather
than a Vim plugin).
- The author accepts patches, and I hope to make it support 3-pane diff.
The pros and cons are also described in the linked Gist.
Per discussion in #2107, I believe "exact" is preferred.
We can also change the default to exact match, but it doesn't always make
sense. Exact match would be useful for branches(), but not for description().
We could define default per predicate function, but I'm pretty sure I cannot
remember which one is which.
git-branchless calls it a substring, so let's do the same.
FWIW, I copied literal:_ from Mercurial, but it's exact:_ in git-branchless.
I have no idea which one is preferred. Since this feature isn't released, we
can freely change it if exact:_ makes more sense.

The syntax is slightly different from Mercurial. In Mercurial, a pattern must
be quoted like "<kind>:<needle>". In JJ, <kind> is a separate parsing node, and
it must not appear in a quoted string. This allows us to report unknown prefix
as an error.
There's another subtle behavior difference. In Mercurial, branch(unknown) is
an error, whereas our branches(literal:unknown) is resolved to an empty set.
I think erroring out doesn't make sense for JJ since branches() by default
performs substring matching, so its behavior is more like a filter.
The parser abuses DAG range syntax for now. It can be rewritten once we remove
the deprecated x:y range syntax.
Similar to other boolean flags, such as "working_copy" or "empty".
We could test something like
`"0000000000000000000000000000000000000000".contains(commit_id)`
like I did for myself, but first of all this is ugly, and secondly the root
commit id is not guaranteed to be 40 zeroes as custom backend implementations
could have some other root.
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.
