opam-file-rs: 使用 Rust 编写的 opam 文件语法的解析器和打印器

解析 OPAM

解析 OPAM 文件。

use opam_file_rs;
fn main () {
  let opam = r#"
    opam-version: "2.0"
    version: "0.1.0"
    name: "opam-file-rs"
    dev-repo: "git+https://github.com/puripuri2100/opam-file-rs"
    license: "MIT"
    maintainer: "Naoki Kaneko <puripuri2100@gmail.com>"
    depends: [
      "lalrpop-util" {>= "0.19.4"}
      "thiserror" {>= "1.0.23"}
    ]
  "#;
  assert!(opam_file_rs::parse(opam).is_ok());
}

转换为 OPAM 文件格式。

可以使用 value::format_opam_file 将数据结构转换为 OPAM 文件格式。

use opam_file_rs;
fn main() {
  let opam_str = r#"
    opam-version: "2.0"
    version: "0.1.0"
    name: "opam-file-rs"
    dev-repo: "git+https://github.com/puripuri2100/opam-file-rs"
    license: "MIT"
    maintainer: "Naoki Kaneko <puripuri2100@gmail.com>"
    depends: [
      "lalrpop-util" {>= "0.19.4"}
      "thiserror" {>= "1.0.23"}
    ]
  "#;
  let opam = opam_file_rs::parse(opam_str).unwrap();
  println!("{}", opam_file_rs::value::format_opam_file(opam));
}
