markup_fmt is a configurable HTML/Vue/Svelte/Astro/Jinja/Twig/Nunjucks/Vento formatter.

Basic Usage

You can format source code string by using format_text function.

use markup_fmt::{config::FormatOptions, format_text, Language};

let options = FormatOptions::default();
assert_eq!("<div class=\"container\"></div>\n", &format_text(
    "<div class=container></div>",
    Language::Html,
    &options,
    |_, code, _| Ok::<_, ()>(code.into()),
).unwrap());

For detailed documentation of configuration, please refer to Configuration on GitHub.

If there're syntax errors in source code, it will return [Err]:

use markup_fmt::{config::FormatOptions, format_text, FormatError, Language, SyntaxError};

let options = FormatOptions::default();
assert!(matches!(
    format_text(
        "<div>",
        Language::Html,
        &options,
        |_, code, _| Ok::<_, ()>(code.into()),
    ).unwrap_err(),
    FormatError::Syntax(SyntaxError { .. })
));

External formatter can return [Err] as well. This error will be aggregated and returned in FormatError::External:

use markup_fmt::{config::FormatOptions, format_text, FormatError, Language};

struct ExternalFormatterError;

let options = FormatOptions::default();
assert!(matches!(
    format_text(
        "<script>a</script>",
        Language::Html,
        &options,
        |_, _, _| Err(ExternalFormatterError),
    ).unwrap_err(),
    FormatError::External(ExternalFormatterError, _)
));
