What is the style for argument values (blue in bright color scheme -a=THIS_STYLE)

[eugenesvk]

I think only 4 are available

  let mut d = Doc::default();
  d.emphasis("emphasis ");
  d.literal("literal ");
  d.invalid("invalid ");
  d.text("text ");

But this is yellow, green, red, white, nothing matches the blue you get for argument value suggestions, which would be helpful if you enumerate such values in the comments

I'm pretty sure that's literal, this is the code used:

bpaf/src/meta_help.rs

Lines 503 to 521 in 88e2f4d

	fn write_shortlong(buf: &mut Doc, name: ShortLong) {
	match name {
	ShortLong::Short(s) => {
	buf.write_char('-', Style::Literal);
	buf.write_char(s, Style::Literal);
	}
	ShortLong::Long(l) => {
	buf.write_str(" --", Style::Literal);
	buf.write_str(l, Style::Literal);
	}
	ShortLong::Both(s, l) => {
	buf.write_char('-', Style::Literal);
	buf.write_char(s, Style::Literal);
	buf.write_str(", ", Style::Text);
	buf.write_str("--", Style::Literal);
	buf.write_str(l, Style::Literal);
	}
	}
	}

where is the = char in this code?

I see = here, could this be it?

        } => {
            buf.token(Token::BlockStart(Block::ItemTerm));
            write_shortlong(buf, *name);
            buf.write_str("=", Style::Text);
            buf.metavar(*metavar);
            buf.token(Token::BlockEnd(Block::ItemTerm));

[eugenesvk]

by the way, is it possible to reformat the .argument::<String>("fDMETHOD") text so that I could fit help here like d|f|k where | symbols wouldn't be colored, but actual argument options d etc would?

[pacak]

Yeah. write_shortlong deals with --via part, = goes as plain text, <fDMETHOD> is gets rendered with .metavar.

At the moment .argument method takes &'static str as metavar so you can't customize it with Doc, but you can still put some ANSI sequence inside to override it to your liking.

[eugenesvk]

Ha, if I add ANSI stuff to replace "fDMETHOD", it seems the width calculation breaks?
format!("{}|{}|{}","d".blue().bold(),"f".blue().bold(),"os".blue().bold());
leads to this misalignment

(note that the closing > isn't styled anymore)

[eugenesvk]

I think direct ANSI colors also negatively affect the width calculations for the comments as now I get word wrapping much earlier
