The author timestamp is rarely useful (in my experience). The
committer timestamp, on the other hand, can be useful for
understanding when a change was most recently modified. IIRC, I
originally picked the author timestamp to match the email (which is
the author's), but it's probably not confusing to use the author email
and the committer timestamp. I suspect few users will even reflect on
it.
The number of lines in the diff output is unchanged.
This makes diffs a little more readable when the "..." would otherwise hide a
single line of code that helps in understanding the surrounding context lines.
This change mostly rearranges the loop that consumes the diff lines, so it can
buffer up to num_context_lines*2+1 lines instead of just num_context_lines.
There's a bit of extra code to handle times when a "..." replaces the last line
of a diff.
Note that `jj diff --git` is unchanged, and will still output `@@` lines that
replace a single line of context.
When a workspace's working-copy commit is updated from another
workspace, the workspace becomes "stale". That means that the working
copy on disk doesn't represent the commit that the repo's view says it
should. In this state, we currently automatically it to the desired
commit next time the user runs any command in the workspace. That can
be undesirable e.g. if the user had a slow build or test run started
in the working copy. It can also be surprising that a checkout happens
when the user ran a seemingly readonly command like `jj status`.
This patch makes most commands instead error out if the working copy
is stale, and adds a `jj workspace update-stale` to update it. The
user can still run commands with `--no-commit-working-copy` in this
state (doing e.g. `jj --no-commit-working-copy rebase -r @ -d @--` is
another way of getting into the stale-working-copy state, by the way).
Also allows several paths to be specified. By default, `jj resolve`
will find the first conflict that matches provided paths (if any)
and try to resolve it.
It seems like I forgot to update the `jj status` output when I decided
(years ago?) that the changes in a commit should always be compared to
the auto-merged parents. I was very confused before I realized that
`jj status` was showing the diff summary against the first parent. I
suppose the fact that `jj status` lists only one parent should have
been a hint. Thanks to ilyagr@ for finding this odd behavior. This
patch fixes it by making the command list all parents, and changes the
diff summary to be against the auto-merged parents.
The `print` command shows the contents of a file, so that is obviously
often more than a page long. Both `hg cat file` and `git show
HEAD:file` page the output.
The output from `files` is often longer than a screen, so the pager is
useful, even though this command is probably used mostly by
scripts. As with `status`, `hg` pages its output, but `git` doesn't.
The status output may be long, so the pager can useful. Now that we
pass `-F` to the pager by default, it should also be fine to use the
pager for short output. For reference, `hg` pages `status` output, but
`git` doesn't.
This command uses an external merge tool to resolve conflicts
simple enough that they can be resolved with a 3-way merge.
This commit provides a very basic version of `jj resolve` that
is hardcoded to use vimdiff.
This also slightly changes the errors of the Diff Editor, so that
both the diff editor and `jj resolve can share an error type.
It implements Deserialize because config.get() requires that. We could instead
add TryFrom<config::Value>, but we'll need Deserialize anyway if we want to
parse a struct containing FullCommandArgs.
I don't know if src/config.rs is the right place, but I feel it's slightly
better than messing up ui.rs.
The example for the `-b` flag was completely incorrect. It looks like
I have copied the example from `-r` and then forgotten to update
it. This fixes that, and also adds some more commits to the example to
hopefully clarify.
Teach Ui's writing functions to write to a pager without touching the
process's file descriptors. This is done by introducing UiOutput::Paged,
which spawns a pager that Ui's functions can write to.
The pager program can be chosen via `ui.pager`. (defaults to Defaults to
$PAGER, and 'less' if that is unset (falling back to 'less' also makes
the tests pass).
Currently, commands are paginated if:
- they have "long" output (as defined by jj developers)
- jj is invoked in a terminal
The next commit will allow pagination to be turned off via a CLI option.
More complex pagination toggling (e.g. showing a pager even if the
output doesn't look like a terminal, using a pager for shorter ouput) is
left for a future PR.
I can't see any reason the user would want to specify revisions
matching the empty string, so let's disallow it. I created a custom
type for revision arguments instead of repeating `value_parser =
NonEmptyStringValueParser::new()`.
If the user creates a branch with an empty name, it seems very likely
to be an accident. Let's help them realize that by erroring out.
I didn't add the same checks to `jj branch delete`, since that would
make it hard to delete a branch with an empty name from existing
repos.
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).
Google employees can read about Google's policy at
go/releasing/contributions#copyright.
The CLI will load aliases from config, insert them one by one, and warn if
declaration part is invalid. That's why RevsetAliasesMap is a public struct
and needs to be instantiated by the caller.
This adds a warning whenever export to the backing Git repo fails,
whether it's by an explicit `jj git export` or an automatic export. It
might be too spammy to print the message after every failed command in
the colocated case, but let's try it and see.
There are no "non-normal" files, so "normal" is not needed. We have
symlinks and conflicts, but they are not files, so I think just "file"
is unambiguous.
I left `testutils::write_normal_file()` because there it's used to
mean "not executable file" (there's also a `write_executable_file()`).
I left `working_copy::FileType::Normal` since renaming `Normal` there
to `File` would also suggest we should rename `FileType`, and I don't
know what would be a better name for that type.
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.
Several lines of red text can be overwhelming, and makes it harder to
tell the hint from the error. Let's separate the hint from the error
instead. This matches what hg does. Having the hints separated out
also means that we could have a single config to turn them off.
I want to add a separate field for a hint, so that can be printed in a
different color (than red). Having a factory function is useful then,
since most call sites don't want to pass a hint. Also, by using a
factory function instead of using the constructor directly means that
we can accept `&str` arguments instead of forcing the caller to
convert a string literal to `String`.
Example:
JJ: Enter commit description for the first part (parent).
Better split commit message
JJ: This part contains the following changes:
JJ: M src/formatter.rs
JJ:
JJ: Lines starting with "JJ: " (like this one) will be removed.
