I'm going to split commit/operation_templater::parse() into two parts, and
the first half will be Commit/OperationTemplateLanguage::new(..). This patch
also makes CommitTemplateLanguage::wrap_() functions public because extension
methods should be able to return property of these types.

This commit fixes the warnings by making the watchman URL a hyperlink and by
disabling the lint for the jj-cli error. Disabling the link is the right thing
to do because the comment is captured by clap and printed when `jj --help`
runs and any markdown formatting like `<>` is passed through.
The ExternalMergeTool struct has four 24-byte fields plus one bool. It could
be shrunk by dropping Vec/String capacity, but the resulting type would still
be bigger compared to the default Builtin variant.
I considered inlining tx.select_diff(), but that looked a bit cryptic because
the arguments orders are reasonably different. This thin wrapper will help
enforce the common interactive editing behavior.
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.
