rhg: upgrade `clap` dependency
This one is the worst one to upgrade since v2 -> v4 broke a ton of API,
which thankfully seems saner now.
Contrary to what was done in the `hg-core/src/examples/nodemap` rewrite,
we're not switching from the "builder" pattern to the "derive" pattern,
since that would imply a much larger diff. It can be done incrementally.
use crate::error::CommandError;
use hg;
use hg::matchers::get_ignore_matcher;
use hg::StatusError;
use log::warn;
pub const HELP_TEXT: &str = "
Show effective hgignore patterns used by rhg.
This is a pure Rust version of `hg debugignore`.
Some options might be missing, check the list below.
";
pub fn args() -> clap::Command {
clap::command!("debugignorerhg").about(HELP_TEXT)
}
pub fn run(invocation: &crate::CliInvocation) -> Result<(), CommandError> {
let repo = invocation.repo?;
let ignore_file = repo.working_directory_vfs().join(".hgignore"); // TODO hardcoded
let (ignore_matcher, warnings) = get_ignore_matcher(
vec![ignore_file],
&repo.working_directory_path().to_owned(),
&mut |_source, _pattern_bytes| (),
)
.map_err(|e| StatusError::from(e))?;
if !warnings.is_empty() {
warn!("Pattern warnings: {:?}", &warnings);
}
let patterns = ignore_matcher.debug_get_patterns();
invocation.ui.write_stdout(patterns)?;
invocation.ui.write_stdout(b"\n")?;
Ok(())
}
