Tool to automatically generate flatpak-builder manifest json from a Cargo.lock.

Poetry users can run poetry install and skip this.

Otherwise install Python 3.8+ with these modules:

• toml
• aiohttp

Generated manifests are supported by flatpak-builder 1.2.x or newer.

Poetry users: first activate your virtualenv by running poetry shell.

Convert the locked dependencies by Cargo into a format flatpak-builder can understand:

python3 ./flatpak-cargo-generator.py ./quickstart/Cargo.lock -o cargo-sources.json

The output file should be added to the manifest like

{
    "name": "quickstart",
    "buildsystem": "simple",
    "build-commands": [
        "cargo --offline fetch --manifest-path Cargo.toml --verbose",
        "cargo --offline build --release --verbose",
        "install -Dm755 ./target/debug/quickstart -t /app/bin/"
    ],
    "sources": [
        {
            "type": "dir",
            "path": "."
        },
        "cargo-sources.json"
    ]
}

Make sure to override CARGO_HOME env variable to point it to /run/build/$module-name/cargo where $module-name is the flatpak module name, quickstart in this example.

For a complete example see the quickstart project.
