`jj chmod` won't operate on conflicts involving non-files on the
positive sides. However, the error message says "None of the sides of
the conflict are files", which is not correct.
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.
We anyway trim the newlines eventually and this just does that eagerly
so we output the "correct" description back to stdout (on describe for
example, we'd now print the first non empty line).
I think I moved way too many functions onto `Merge<Option<TreeValue>>`
in 82883e648da4. This effectively reverts almost all of that
commit. The `Merge<T>` type is simple container and it seems like it
should be at fairly low level in the dependency graph. By moving
functions off of it, we can get rid of the back-depdencies from the
`merge` module to the `conflict` module that I introduced when I moved
`Merge` to the `merge` module. I'm thinking the `conflict` module can
focus on materialized conflicts.
Two things will be added:
a. show warning if child exited with non-zero status
b. attach pager stdin to stderr of child process
I think (a) could be propagated from generate_diff() as an error variant, but
for (b), it makes sense to pass ui down to the function.
Since `Conflict<T>` can also represent a non-conflict state (a single
term), `Merge<T>` seems like better name.
Thanks to @ilyagr for the suggestion in
https://github.com/martinvonz/jj/pull/1774#discussion_r1257547709
Sorry about the churn. It would have been better if I thought of this
name before I introduced `Conflict<T>`.
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.
