Support alternative notations for subscript/superscript

[rogueai]

Hi, first of all thanks for your library, it's definitely one of the most comprehensive parsers for org, and the ast traverser makes it extremely easy to write custom exporters!

I have a question about subscripts and superscripts: in my org config I've set the subscripts to only accept the {} notation with:

(setq org-use-sub-superscripts '{})

that means only a_{b} will be exported as subscript and not a_b, and the same applies for superscripts.

Is there a way to configure orgize to do the same, or is it something that would need to be implemented on your side?

Thanks!

hello, I just published v0.10.0-alpha.10 to crates.io. This version adds control over sub/superscript parsing via the use_sub_superscript field in ParseConfig:

use orgize::{config::UseSubSuperscript, Org, ParseConfig};

let org = ParseConfig {
    use_sub_superscript: UseSubSuperscript::Brace,
    ..Default::default()
}
.parse("a_b, a_{b}");

assert_eq!(
    org.to_html(),
    "<main><section><p>a_b, a<sub>b</sub></p></section></main>"
);

let org = ParseConfig {
    use_sub_superscript: UseSubSuperscript::Nil,
    ..Default::default()
}
.parse("a_b, a_{b}");

assert_eq!(
    org.to_html(),
    "<main><section><p>a_b, a_{b}</p></section></main>"
);
