FluentCI Engine is a programmable CI/CD engine (used by FluentCI) that is designed to be simple, flexible, and easy to use. It is supposed to run on the host machine without containerization or virtualization, and it is designed to be used with Nix, Pkgx, Devbox, Flox, Devenv, EnvHub, Pixi and Mise.
Note
Project Status: 🐲 Unstable, alpha-ish quality. This project is still in the early stages of development, and it is not yet ready for production use. It is not feature-complete, and it is not yet stable. Use at your own risk.

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.
Create a new Rust project:
cargo new nix --libInstall the extism_pdk, fluentci_types and fluentci_pdk crates:
cargo add extism_pdk fluentci_types fluentci_pdkSave 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-unknownRun the plugin:
fluentci-engine call -m ./target/wasm32-unknown-unknown/release/nix.wasm -- exec nix --version- android

FluentCI Plugin Development Kit (fluentci_pdk) provides some builtin functions from that you can use in your plugins:
Setup a Devbox Environment.
Example:
dag()
.devbox()?
.with_exec(vec!["devbox", "version"])?
.stdout()?;Setup a Devenv Environment.
Example:
dag()
.devenv()?
.with_exec(vec!["devenv", "version"])?
.stdout()?;Load a directory at the given path.
Example:
dag()
.directory(".")?
.with_exec(vec!["ls", "-la"])?
.stdout()?;Setup an EnvHub Environment.
Example:
dag()
.envhub()?
.with_exec(vec!["envhub", "--version"])?
.stdout()?;Load a file at the given path.
Example:
dag()
.file("Cargo.toml")?
.path()?;Setup a Flox Environment.
Example:
dag()
.flox()?
.with_exec(vec!["flox", "--version"])?
.stdout()?;Load a Git repository at the given URL.
Example:
dag()
.git("https://github.com/tsirysndr/me")?
.branch("main")?
.tree()?
.entries()?;Load a HTTP resource at the given URL.
Example:
dag()
.http("https://example.com")?
.path()?;Setup a Mise Environment.
Example:
dag()
.mise()?
.with_exec(vec!["mise", "--version"])?
.stdout()?;Setup a Nix Environment.
Example:
dag()
.nix(NixArgs {
impure: true
})?
.with_exec(vec!["nix", "--version"])?
.stdout()?;Create a new pipeline.

hello Hello, World!FluentCI Engine supports caching. To enable it, set the following environment variables:
FLUENTCI_CACHE_GCS_BUCKET- GCS bucket name, if you are using Google Cloud StorageFLUENTCI_CACHE_S3_ENDPOINT- S3 endpoint, if you are using S3-compatible storageFLUENTCI_CACHE_S3_BUCKET- S3 bucket name, if you are using S3-compatible storageFLUENTCI_CACHE_CDN_ENDPOINT- CDN endpoint, if you are using CDN (optional) for downloading cache
Note
You need to set GOOGLE_APPLICATION_CREDENTIALS or AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables to use GCS or S3 cache.
FluentCI Engine supports OpenTelemetry tracing. To enable it, set the OTEL_EXPORTER_OTLP_ENDPOINT or OTEL_EXPORTER_ZIPKIN_ENDPOINT (if you want to use Zipkin) environment variable to the desired endpoint.
FluentCI Engine supports sending logs to Baselime. To enable it, set the BASELIME_API_KEY environment variable to the desired API key.
