Remove `rustc_session::config::rustc_short_optgroups` by Zalathar · Pull Request #132891 · rust-lang/rust

Zalathar · 2024-11-11T05:47:59Z

The name rustc_short_optgroups has always been confusing, because it is unrelated to the distinction between short and long options (i.e. -s vs --long), and instead means something like “the subset of command-line options that are printed by rustc --help without -v”.

So let's merge that function into the main rustc_optgroups, and store the relevant bit of information in a boolean field in RustcOptGroup instead.

This PR also modifies RustcOptGroup to store its various strings directly, instead of inside a boxed apply closure. That turned out to not be necessary for the main change, but is a worthwhile cleanup in its own right.

Very nice cleanup! One minor naming nit then r=me.

+ /// Display name for this option. Normally equal to `long_name`, except for
+ /// options that don't have a long name.
 pub name: &'static str,


Suggestion: display_name? We have short_name and long_name below, so having just name feels a bit confusing.

So, in the process of looking into this, I remembered that things are actually more complicated.
We do use this as a display name, but it also gets used for other things, such as matching against the option name reported by some getopts errors.
So I'm going to push a better comment, but now I don't like the idea of trying to rename name in this PR.

Yes, that's fine with me.

+ /// If true, this option should not be printed by `rustc --help`, but
+ /// should still be printed by `rustc --help -v`.
+ pub is_verbose_help_only: bool,


Remark: yes thank you, this is so much clearer.

Revised comment for name(diff), in light of the fact that it's not just a display name.

@rustbot ready
