This constructor has too many arguments enough to introduce a parameter struct,
which would be identical to the CommandHelper type. Let's simply inline it as
there are no external callers.
write!(ui.hint(), ..) error is suppressed because it seemed weird if the
configuration error had io::Error variant. The write error isn't important
anyway.
This moves the config loading closer to CLI args where --tool=<name> option
will be processed. The factory function are proxied through the command helper
so that the base_ignores can be attached there later.
I'm going to make them be loaded by caller, and these newtypes will provide
extra compile-time safety (plus nicer API to be added later.) The error types
will be cleaned up later patches.
This gets rid of the last UserSettings dependency from edit_diff_external().
I'm going to remove it from edit_diff() too, and let callers pass a
preconfigured MergeTool struct instead.
These changes will make it easier to add --tool=<name> argument #2575.
Because the snapshot directory is removed at the end of the function, it doesn't
make sense to enable watchman in it. The max_new_file_size parameter might be
somewhat useful, but it's unlikely that the temporary directory contains
gigantic node_modules tree for example. OTOH, the base_ignores matters since it
may contain common ignore patterns like *~.
This eliminates most of the UserSettings dependencies from this function.
I'm going to add string.len() method which will return a length in bytes. The
number of the UTF-8 code points is useless metrics, and strings here are often
ASCII bytes, so let's simply use byte indices in substr().
If the given index is not at a char boundary, it will be rounded. I considered
making it an error, but that would be annoying. I would want to see something
printed by author.name().substr() even if it contained latin characters.
I've extracted index normalization function which might be used by other string
methods. The remaining part of substr() is trivial, so inlined it.
Before, --tool=:builtin argument was ignored and the tool was loaded from
"ui.diff.tool" option. Since there is no single builtin diff format, :builtin
doesn't make sense here. Maybe we can translate ":<format>" to the internal
diff format instead, but that will also mean "ui.diff.tool" and ".format" can
be merged.
This partially reverts 409356fa5b "merge_tools: enable `:builtin` as default
diff/merge editor."
I'm going to split get_tool_config() to fix "diff --tool=:builtin", and it
doesn't make sense to duplicate get_tool_config_from_args() per backing
get_tool_config() functions.
This make :builtin render conflicts as conflict markers instead of
panicking. To support conflicts properly, we also need to parse the
conflict markers (calling `update_from_content()`) after the user
closes the editor.
A runtime error will be printed inline. This simplifies error handling, and I
think it's better behavior overall. "jj log" won't be terminated just because
"gpg" crashed during signature verification for example. When property
evaluation failed, the error propagates to the closest template expression, and
the error message is printed there. Then, template output continues as long as
the output stream is open.
If we add revset() function for example, dynamic revset evaluation error will be
displayed inline. Static revset expression will still be processed at parsing
phase (to cache the evaluation result), and the error will be reported early.
One caveat: a string argument passed to e.g. .contains(needle) can be a
template, so the evaluation error would be swallowed there.
It was moved to CLI at 42252a2f00 "cli: on `jj init --git-repo=.`, use
relative path to `.git/`." As far as I can tell, .canonicalize() is needed
to calculate relative path, which is now processed differently in
Workspace::init_external_git() and GitBackend::init_external().
This reverts dc074363d1 "no-op: Move external git repo canonicalization into
Workspace::init_git_external." As I said in the PR comment, appending ".git"
is normalization of the user input, which is IMHO more appropriate to be done
in the CLI layer.
The translation from method error to keyword error can go wrong if the context
object had n-ary methods (n > 0), which isn't the case as of now. For
simplicity, arguments error is mapped to "self.<name>(..)" suggestion.
Local variables and "self" could be merged without using extra method, but
we'll need extend_*_candidates() to merge in symbol/function aliases anyway.
This seems more useful if aliases are nested. The innermost error usually
contains the problem, and the outer errors are contexts where aliases are
expanded.
Except for the generic list and template methods. We'll need a bit more
refactoring to migrate List<T> method builders to be compatible with
non-capturing fn() type.
The recovery commit we create when we run into a stale working copy
with a missing operation currently has an empty tree. Our commit
backend at Google creates an index of which files changed in each
commit. That gets really expensive when a commit deletes all files in
the repo, as these recovery commits do. So for our backend, it is much
better to make the recovery commit empty instead. That's what this
patch does.
It almost doesn't matter functionally what tree we use for it since we
don't care much about the current tree when snapshotting the working
copy. It does matter in a few cases, however. One case is for
conflicts. In that case, it's likely better to use the recovery
commit's parent as base tree (as we do by making the recovery commit
empty) than to use an empty tree, as that would guarantee that all
conflicts would be considered resolved. (Side note: perhaps we should
start looking at the current commit's parent instead of looking at the
current commit when snapshotting, but that's a topic for another day.)
When we abandon a working-copy commit, we create a new working-copy
commit on top. This behave is very useful, but it's not obvious. Let's
document it.
Thankfully, 2bbefcc338 (rewrite: default to not simplifying ancestor
merges) means that there are much fewer commands where we need to
document this behavior.
There are two major goals:
* provide typo hints in a similar way to revset
* make methods extensible
The created method table is bound to the 'repo lifetime because of the problem
described in the inline comment. It would be nice if we can build cachable
core method table for<'repo> CommitTemplateLanguage<'repo, '_>, but I couldn't
figure out how.
Add an option to list tracked branches only
This option keeps most of the current `--all` printing logic, but:
- Omits local Git-tracking branches by default (can be extended to
support filtering by remote).
- Skip over the branch altogether if it doesn't contain tracked remotes
- Don't print the untracked_remote_refs at the end
Usage:
`jj branch list -t`
`jj branch list --tracked`
`jj branch list --tracked <branch name>`
I think the user usually wants to abandon only newly empty commits. I
think they should use `jj abandon` if they want to get rid of already
empty commits. By keeping already empty commits, we don't need to
special-case the working copy and merge commits.
This allows us to call alias function with the top-level object.
For convenience, all self.<method>()s are available as keywords. I don't think
we'll want to deprecate them. It would be tedious if we had to specify
-T'self.commit_id()' instead of -Tcommit_id.
If I remember correctly, wrap_fn() was added to help type inference. It no
longer makes sense because the type is coerced by TemplateFunction::new()
and language.wrap_*().
