android_bp 0.3.1

android-bp

a rust crate to parse Android.bp files

Usage

    use android_bp::BluePrint;

    let bp = BluePrint::from_file("fixtures/example.bp").unwrap();
    println!("{:#?}", bp);

    // variables are accessible as a rust HashMap
    println!("{:#?}", bp.variables);
    for m in &bp.modules {
        if m.typ == "rust_binary" {
            println!("{:?}", m.get("name").unwrap());
        }
    }
    // or iter them by type
    for m in bp.modules_by_type("rust_host_test") {
        // m.get return an sometime inconvenient Option<&Value>
        // so some helper methods are provided
        let name = m.get_string("name").unwrap();
        let srcs = m.get_array("srcs").unwrap();
        println!("{:?} {:?}", name, srcs);
    }

Status

• The project parses successfully all the Android.bp files in the AOSP tree. Test files are present in the src/test_db.tar.xz archive.

• different possible values are abstracted in the Value enum

  • strings
  • arrays
  • integers
  • booleans
  • expressions
  • functions
  • identifiers

• modules (module { ... })

• variables (var = "value")

• variables extend (var += [ "new value" ])

  • arrays
  • strings
  • integers
  • expressions with other variables

• expressions (var : "value" + \n"value"), used for strings long enough to be split in multiple lines

  • arrays (automatically merged)
  • strings (automatically merged)
  • with identifiers (kept as an expression)
