@joyously found `o` confusing because it's a valid change id prefix. I
don't have much preference, but `●` seems fine. The "ascii",
"ascii-large", and "legacy" graph styles still use "o".
I didn't change `@` since it seems useful to have that match the
symbol used on the CLI. I don't think we want to have users do
something like `jj co ◎-`.
The name of the [alias] section is inconsistent with other
table-valued sections ([revset-aliases], [colors], [merge-tools]), so
let's rename it. For comparison, `Cargo.toml` also uses plural names
(e.g. `[dependencies]`).
I don't think need to write non-UTF8 bytes to our config files. If we
ever do (maybe to test that we give the user a reasonable error
message), we add a custom function for that.
This is ugly, but we need a special case because root_change_id and
root_commit_id aren't equal but share the same prefix bytes. In practice,
no one would care for the shortest root id prefix, but we'll need to deal
with a similar problem when migrating prefix id resolution to repo layer.
Let's use `crossterm` to make `ColorFormatter` a little more readable,
and maybe also more portable.
This uses the `SetForegroundColor()` function, which uses the escapes
for 256-color support (code 38) instead of the 8-color escapes (codes
30-37) combined with bold/bright (code 1) we were using before. IIUC,
most terminals support the 16 base colors when using the 256-color
escape even if they don't support all the 256 colors. It seems like an
improvement to use actual color codes for the bright colors too,
instead of assuming that terminals render bold as bright (even though
most terminals do).
Before this commit, we relied on ANSI escape 1 - which is specified to
make the font bold - to make the color brighter. That's why we call
the colors "bright blue" etc. When we switch from using code 30-37 to
using 38 to let our color config just control the color (not using
escape1), we therefore lose the bold font on many terminals (at least
in iTerm2 and in the terminal application on my Debian work
computer). As a workaround, I made us still use escape 1 when the
bright colors are used. I'll make boldness a separately configurable
attribute soon. Then we'll be able to remove this hack.
With the switch to `crossterm`, we also reset just the foreground
color (code 39) instead of resetting all attributes (code 0). That
also seems like an improvement, probably making it easier for us to
later support different background colors, underlining, etc.
Unfortunately, config::Value is lax and '[7]' could be parsed as '["7"]'.
I don't like it, but I think that's actually better for consistency as we
use config.get_string() in various places.
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).

In the test case `test_branch_mutually_exclusive_actions`, we weren't actually testing anything useful, because the interface has since changed to use subcommands instead of options. The test has been deleted in this commit, and `TestEnvironment::jj_cmd_cli_error` has been changed to return a `#[must_use]` `String` representing stderr. I also added `#[must_use]` to `TestEnvironment::jj_cmd_failure` while I was here.
We have talked about showing the commit ID only for divergent changes
because it's generally easier to work with the change ID, and it's
less likely to result in a divergent change. However, it's useful to
have the commit ID available for pasting into e.g. a commit message or
the GitHub UI. To try to steer users towards using the change ID, this
commit moves the commit ID off to the right in the log output.
I put it just after the "divergent" field, because that makes it close
to how I imagine it would look if we decided to hide the commit ID
except for divergent changes. I was thinking that could be rendered as
"divergent (abc123)". So if we add config to hide the commit ID, then
it would be rendered almost the same for divergent commits (just with
the added parentheses). It would also make sense to replace the
"divergent" field by a question mark on the change ID, since change
IDs basically behave like branches. If we do that, then the placement
of the commit ID I picked in this commit does not make sense.
Given how easy this was, I can't believe I didn't make the change
sooner.
I haven't updated the screenshots in the readme because I plan to make
some further changes to the default template. I'll update them after
those changes.
It can be confusing that some commits (typically the working copy)
don't have a description. Let's show a placeholder text in such cases.
I chose the format to match the "(no email configured)" message we
already have.
Our support for aliases is very naively implemented; it assumes the
alias is the first argument in argv. It therefore fails to resolve
aliases after global arguments such as `--at-op`.
This patch fixes that by modifying the command defintion to have an
"external subcommand" in the list of available commands. That makes
`clap` give us the remainder of the arguments when it runs into an
unknown command. The first in the list will then be an alias or simply
an unknown command. Thanks to @epage for the suggestion on in
clap-rs/clap#3672.
With the new structure, it was easy to handle recursive alias
definitions, so I added support for that too.
Closes#292.
