deb822 样式文件的无损解析器

本 crate 包含用于 Debian 中使用的 RFC822 样式文件的无损解析器和编辑器。

基于此 crate 的三个相关 crate 是

• debian-control
• debian-copyright
• dep3

示例

use deb822_lossless::Deb822;
use std::str::FromStr;

let input = r#"Package: deb822-lossless
Maintainer: Jelmer Vernooij <[email protected]>
Section: rust

Package: deb822-lossless
Architecture: any
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.

"#;

let deb822 = Deb822::from_str(input).unwrap();
assert_eq!(deb822.paragraphs().count(), 2);

lib.rs:

deb822 样式文件的无损解析器。

此解析器可以用来解析 deb822 格式的文件，同时保留所有空白和注释。它基于 [rowan] 库，这是一个 Rust 的无损解析库。

一旦解析完成，文件可以被遍历或修改，然后写回文件。
