We usually print stats at the end of mutable operation, and I think these
messages are useful even if N = 1. I understand that "Deleted N" (N > 1) is
unusual and the original intent of these messages was to signal possible
mistakes. However, I don't think printing N=1 stats would nullify the original
purpose.
No emptiness check is needed for delete/forget, but names can be empty in
track/untrack because of noop changes.
The last hunk could be truncated instead, but the .peekable() version is easier
to follow. If we truncated lines, we would have to adjust line ranges
accordingly.
show_context_after was set once when DiffHunk::Different received, and was
never turned off. This means DiffHunk::Matching is not supposed to repeat.
Under this condition, we can assume that removed/added lines exist if lines
isn't empty.
At work, a user encountered a panic upon attempting to create a dir at
the line in the diff below, but it turned out to be difficult to debug
because I didn't know what the path was. There already is a mechanism to
add path context in the lib crate; make it available in the cli crate as
well, and use the mechanism to add path context to "workspace add".
It's common to create empty working-copy commits while using jj, and
currently the author timestamp for a commit is only set when it is first
created. If you create an empty commit, then don't work on a repo for a
few days, and then start working on a new feature without abandoning the
working-copy commit, the author timestamp will remain as the time the
commit was created rather than being updated to the time that work began
or finished.
This commit changes the behavior so that discardable commits (empty
commits with no description) by the current user have their author
timestamps reset when they are rewritten, meaning that the author
timestamp will become finalized whenever a commit is given a description
or becomes non-empty.
Now, the command for `jj git remote add` is `cmd_git_remote_add` and its
argument type is `GitRemoteAddArgs`. This should make it easier to find
the CLI docs and the implementation for commands.
This is how `jj branch` commands were already set up in this way. The
`jj op` commands were also already set up in this way, except the
functions are called e.g. `cmd_op_undo`, I kept this for simplicity.
I was mainly motivated by the `jj file` commands. Most other commands
had functions already named in the above pattern, but used to have
shorter argument type names.
We have two other kinds of working copies at Google and it's sometimes
useful to get the basic information about operation id and tree id for
them, for exampel for debugging stale workspaces. This patch adds a
command for that.
We could instead have made the old `jj debug working-copy` command
work for all kinds of working copies (like the new command) and only
have extra information for the standard local-disk implementation. I
don't feel strongly either way and could do it other other way instead
if people prefer that.
While explaining branch tracking behavior, I find it's bad UX that a deleted
branch can be re-"create"d with tracking state preserved. It's rather a "set"
operation. Since deleted tracking branch is still listed, I think it's better
to assume that the local branch name is reserved.

Renaming to deleted tracking branch is still allowed (with warning) because the
"rename" command can't handle tracked remotes very well. If it were banned, bad
rename couldn't be reverted by using "jj branch rename". It would be confusing
if "rename a b" succeeded with warning, but the following "rename b a" failed.
This will help inline view.remove_branch() in cmd_branch_forget(). I don't
care much about owned (String, _) vs (&str, _), but we can't simplify the
lifetime issue in find_forgettable_branches() anyway. So I made all callers
pass cloned Arc<ReadonlyRepo> and borrow (name, target) pairs from there.
It was convenient that expression nodes can be compared in tests, but no
equivalence property is needed at runtime. Let's remove Eq/PartialEq to
simplify the extension support.
We now have two `cmd_show` in the repo. I think this one should become
`cmd_file_show`, but this should be done uniformly over all the commands
for consistency.
I did *not* keep `print` as an alias (I couldn't find a compelling
reason to do it), but let me know if anyone feels like keeping it.
We don't want e.g. `jj diff --git` to have underlined text because
it's redundant there. This patch fixes that by adding a new `token`
label used only in the color-words diff (for now - it may be used in
git diffs in the future).
This means we could remove the `line_number` label but I left it
because there's little harm in having it and it seems like it can
still be useful.
Thanks to @yuja for noticing and suggesting the fix.
If you want to set a background color on added/removed lines, you
currently get the same style on the line numbers. This patch lets you
specify a different style by overriding it on the line numbers.
Since "set <thing>" often adds a <thing> if not exists, it make some sense
that "branch set" does upsert. The current "branch set" use case is now covered
by "branch move", so it's okay to change the "set" behavior.
If new branch is created by "branch set", status message and hint will be
printed to help migration. The user should be able to undo creation if it was
a mistake.
Closes#3584
