Crate chic

Pretty parser error reporting.

Examples

use chic::Error;

let src = r#"This is an example
content of the slice
which will be annotated
with the list of annotations below.
"#;

let msg = Error::new("expected type, found `x`")
    .error(260, 0, 12, src, "found `x`")
    .help("try using a foobs intead")
    .to_string();

println!("{}", msg);

Outputs:

error: expected type, found `x`
    |
260 | This is an example
    | ^^^^^^^^^^^^ found `x`
    |
    = help: try using a foobs instead

Or convert an io::Cursor to an annotated error:

use std::io::Cursor;
use chic::Error;

let cursor = Cursor::new(
    r#"This is an example
content of the slice
which will be annotated
with the list of annotations below.
"#,
);

let line = 1;
let start = cursor.position() as usize;
let end = cursor.get_ref().len() as usize;
let code = cursor.into_inner();

let msg = Error::new("expected type, found `x`")
    .error(line, start, end, code, "found `x`")
    .help("try using a foobs instead")
    .to_string();

println!("{}", msg);
