For the same reason as the previous commit.
Created and moved stats are printed separately because it's unusual to do both
within one "branch set" invocation.
For the same reason as cdc0cc3601. This will help notice problems like wrong
target revision.
The warning for multiple branches is reorganized as a hint for "-r" option,
which I think is the main purpose of this warning. Unlike "squash", we don't
check if an argument can be parsed as a revset because branch name is usually
a valid symbol expression.
The output looks somewhat similar to color-words diffs. Unified diffs are
verbose, but are easier to follow if adjacent lines are added/removed + modified
for example.
Word-level diffing is forcibly enabled. We can also add a config knob (or
!color condition) to turn it off to save CPU time.
I originally considered disabling highlights in block insertion/deletion, but
that wasn't always great. This can be addressed separately as it also applies
to color-words diffs. #3958
Forgetting a workspace removes its working-copy commit, so it makes
sense for it to be abandoned if it is discardable just like editing a
new commit will cause the old commit to be abandoned if it is
discardable.
It's nice to see the result of "branch move", "create", etc., and this is more
important in "branch move" because the source branches can be specified in an
abstracted way. I originally considered printing a list of affected branches,
but it looked rather verbose. Since the destination revision is unique, we can
use commit_summary template instead.
This patch also removes a warning about multiple branches because the branch
names are included in the commit summary. I think the hint message is good
enough to signal possible mistake.
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.
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.
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.
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.
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
There are several bugs in both the tests and in the implementation
that are made more clear by showing the log output before and after
running the command.
This allows users to jump to the next conflict in the ancestors or children of
the start commit.

In a repo of mine I wanted to do something like the following to push all of my
leaves to the remote as backup:
jj git push -c 'all:heads(base::) & mine() ~ empty()'
But couldn't, because `jj git push` doesn't handle large revsets, even though
it does handle multiple `-c` arguments, so I had to work out some pipe-to-xargs
command instead.

The follow up diff will make `-c` accept large revsets, so it won't make any
sense to print out the original expression when multiple branches will be
created from it.

The error message that says something like 'Workspace "default"
doesn't have a working copy' confused me when I saw it. The problem
it's describing is that the repo view doesn't have a working-copy
commit for the given workspace id. Saying "working-copy commit"
instead of "working copy" hopefully clarifies it a bit.
