Crate deb822_lossless
source ·Expand description
Lossless parser for deb822 style files.
This parser can be used to parse files in the deb822 format, while preserving all whitespace and comments. It is based on the rowan library, which is a lossless parser library for Rust.
Once parsed, the file can be traversed or modified, and then written back to a file.
§Example
use deb822_lossless::Deb822;
use std::str::FromStr;
let input = r#"Package: deb822-lossless

Language
trait teaches rowan to convert between these two SyntaxKind types, allowing for a nicer SyntaxNode API where “kinds” are values from ourenum SyntaxKind
, instead of plain u16 values. - Let’s start with defining all kinds of tokens and composite nodes.
