gomod-rs

A go.mod file parser with location information.

Implemented using nom and nom_locate.

No string copy/clone during parsing.

(except for interpreted strings, which yield Identifier::Interpreted(String) type)

Example Usage

Here is an example printing all requirements defined in a go.mod file, along with their locations and related contents.

use gomod_rs::{parse_gomod, Context, Directive};

let contents = r#"
"#;
let gomod = parse_gomod(&contents)?;
gomod
    .iter()
    .filter_map(|i| match i {
        Context {
            value: Directive::Require { specs },
            ..
        } => Some(specs),
        _ => None,
    })
    .for_each(|require_specs| {
        require_specs.iter().for_each(|spec| {
            println!(
                "Requirement {{name: {}, version: {}}} at line {}, fragment: {}",
                spec.value.0,
                &spec.value.1 as &str,
                spec.range.0.line,
                &contents[spec.range.0.offset..spec.range.1.offset]
            );
        });
    });
