Unlike Mercurial, this isn't a template keyword/function, but a config knob.
Exposing graph_width to templater wouldn't be easy, and I don't think it's
better to handle terminal wrapping in template.
I'm not sure if patch content should be wrapped, so this option only applies
to the template output for now.
Closes#1043
The parameter order follows indent()/label() functions, but this might be
a bad idea because fill() is more likely to have optional parameters. We can
instead add template.fill(width) method as well as .indent(prefix). If we take
this approach, we'll probably need to add string.fill()/indent() methods,
and/or implicit cast at method resolution. The good thing about the method
syntax is that we can add string.refill(), etc. for free, without inventing
generic labeled template functions.
For #1043, I think it's better to add a config like ui.log-word-wrap = true.
We could add term_width/graph_width keywords to the templater, but the
implementation would be more complicated, and is difficult to use for the
basic use case. Unlike Mercurial, our templater doesn't have a context map
to override the graph_width stub.
A list type isn't so useful without a map operation, but List<CommitId>
is at least printable. Maybe we can experiment with it to craft a map
operation.
If a map operation is introduced, this keyword might be replaced with
"parents.map(|commit| commit.commit_id)", where parents is of List<Commit>
type, and the .map() method will probably return List<Template>.
The argument order is different from Mercurial's indent() function. I think
indent(prefix, content) is more readable for lengthy content. However,
indent(content, prefix, ...) might be better if we want to add an optional
firstline_prefix argument.
This eliminates ambiguous parsing between "func()" and "expr ()".
I chose "++" as template concatenation operator in case we want to add
bit-wise negate operator. It's also easier to find/replace than "~".
The outermost "op-log" label isn't moved to the default template. I think
it belongs to the command's formatter rather than the template.
Old bikeshedding items:
- "current_head", "is_head", or "is_head_op"
=> renamed to "current_operation"
- "templates.op-log" vs "templates.op_log" (the whole template is labeled
as "op-log")
=> renamed to "op_log"
- "template-aliases.'format_operation_duration(time_range)'"
=> renamed to 'format_time_range(time_range)'
Now that we use headers to define `[template-aliases]`, I thought we should explain how they are also equivalent to dotted keys.
Alternatively, we could rewrite them all in the dotted style, but it would look awkward.
I'm going to remove the corresponding config knobs.
As an example of "brackets" short id, I put a simplified version. It's
unlikely that the "rest()" gets empty for hashes of 12-char long.
We have made some changes to CLI output that had not made it into the
tutorial. It's time to update it, especially with the new change id
rendering. Since I'm updating it now, and since it's a bit of work to
do so, I decided to use GitHub's Hello-World repo instead of jj's own
repo as our example.
Supported values are,
- `none` for no author information,
- `full` for both the name and email,
- `name` for just the name,
- `username` for username part of the email,
- (default) `email` (or any other gibberish for that matter) for the full email.
For stock merge-tools, having name -> args indirection makes sense. For
user-specific settings, it's simpler to set command name and arguments
together.
It might be a bit odd that "name with whitespace" can be parsed differently
depending on the existence of merge-tools."name with whitespace".
I keep calling it `underline` by mistake, so that probably means that
it's a more natural name for it. We haven't made a release of it yet,
so I didn't mention it in the changelog.
I didn't update all variables to also use `underline`, because I felt
that `underlined` was usually more natural there, plus crossterm calls
it `Attribute::Underlined`.
Add a new git.auto-local-branch config option. When set to false, a
remote-tracking branch imported from Git will not automatically create a
local branch target. This is implemented by a new GitSettings struct
that passes Git-related settings from UserSettings.
This behavior is particularly useful in a co-located jj and Git repo,
because a Git remote might have branches that are not of everyday
interest to the user, so it does not make sense to export them as local
branches in Git. E.g. https://github.com/gitster/git, the maintainer's
fork of Git, has 379 branches, most of which are topic branches kept
around for historical reasons, and Git developers wouldn't be expected
to have local branches for each remote-tracking branch.
I think of it more as style than a format, so using `style` in the
config key makes sense to me.
I didn't bother making upgrades easy by supporting the old name since
this was just released and only a few developers probably have it set.
The heading says it's going to explain aliases, but it doesn't, and
now that we've documented aliases in config.md, we probably don't need
to mention it in the tutorial.
