🧩 Plugins

FluentCI Engine supports plugins in WebAssembly. You can write your own plugins in Rust or any other language that can compile to WebAssembly. See examples for more information.

🦀 Rust Plugin Example

Create a new Rust project:

cargo new nix --lib

Install the extism_pdk, fluentci_types and fluentci_pdk crates:

cargo add extism_pdk fluentci_types fluentci_pdk

Save the following code to src/lib.rs:

use extism_pdk::*;
use fluentci_pdk::dag;
use fluentci_types::nix::NixArgs;

#[plugin_fn]
pub fn exec(command: String) -> FnResult<String> {
    let stdout = dag()
        .nix(NixArgs {
            impure: true
        })?
        .with_exec(command.split_whitespace().collect())?
        .stdout()?;
    Ok(stdout)
}

Set the following in your Cargo.toml:

[lib]
crate-type = ["cdylib"]

Compile the plugin to WebAssembly:

cargo build --release --target wasm32-unknown-unknown

Run the plugin:

fluentci-engine call -m ./target/wasm32-unknown-unknown/release/nix.wasm -- exec nix --version
