To support tree-level conflicts, we're going to need to update the
working copy from one `MergedTree` to another. We're going need to
store multiple tree ids in the `tree_state` file. This patch gets us
closer to that by getting the diff from `MergedTree`s`, even though we
assume that they are legacy trees for now, so we can write to the
single-tree `tree_state` file.
Many of the `TreeBuilder` users have an `Option<TreeValue>` and call
either `set()` or `remove()` or the builder depending on whether the
value is present. Let's centralize this logic in a new
`TreeBuilder::set_or_remove()`.
`revset::parse()` already has a `RevsetWorkspaceContext` argument, so
I think it makes sense to put that and the other context arguments
into a larger `RevsetParseContext` object.
We resolve file paths into repo-relative paths while parsing the
revset expression, so I think it's consistent to also resolve which
workspace "@" refers to while parsing it. That means we won't need the
workspace context both while parsing and while resolving symbols.
In order to break things like `author("martinvonz@")` (thanks to @yuja
for catching this), I also changed the parsing of working-copy
expressions so they are not allowed to be
quoted. `author(martinvonz@)` will therefore be an error now. That
seems like a small improvement anyway, since we have recently talked
about making `root` and `[workspace]@` not parsed as other symbols.
Custom binaries will often want to provide e.g. additional command
aliases, additional revset aliases, custom colors, etc. This adds a
mechanism for them to do that.
This commit replaces the functions `UserSettings::user_name_placeholder()`` and
`UserSettings::user_email_placeholder()` with `const` `&str`s to emphasize that
the placeholder strings must not be changed to support commits without
names or email addresses made before this change.
Maybe we could load GitBackend without resolving .git symlink, but that would
introduce more subtle bugs. Instead, we calculate the expected Git workdir path
from the canonical ".git" path.
Fixes#2011
Summary: In preparation for unifying all workspace dependencies across all
crates, let's go ahead and move the jj-cli crate into its own new directory.
This will also be a nicer and more uniform layout as we add new `jj-*` crates.
