# CLI Batteries

Opinionated batteries-included command line interface runtime utilities.
To use it, add it to your `Cargo.toml`
```toml
[dependencies]
cli-batteries = "0.1"
[build-dependencies]
cli-batteries = "0.1"
```
and call the [`build_rs`] function in your `build.rs`
```rust,ignore
fn main() {
cli_batteries::build_rs().unwrap()
}
```
Then in your `src/main.rs` you define app specific command line arguments using [`clap::Parser`][clap] and run the app as follows
```rust,ignore
use cli_batteries::{version, Parser};
use std::{path::PathBuf, io::Result};
use tokio::fs::File;
#[derive(Parser)]
#[group(skip)]
struct Options {
/// File to read
#[clap(long, env, default_value = "Readme.md")]
file: PathBuf,
}
async fn app(options: Options) -> Result<()> {
let mut file = File::open(options.file).await?;
Ok(())
}
fn main() {
cli_batteries::run(version!(), app);
}
```
You can see this working in the [example project](./example).
## Features
* `signals`: Handle Ctrl-C, SIGINT and SIGTERM with gracefull shutdown.
* `mimalloc`: Use the [mimalloc] allocator with security hardening features enabled.
* `rand`: Log and configure random seeds.
* `rayon`: Log and configure number of threads.
* `prometheus`: Start a Prometheus metrics server.
* `metered-allocator`: Collect metric on memory allocation, enables `prometheus`.
* `mock-shutdown`: Enable the `reset_shutdown` function that allows re-arming shutdown for testing.
* `tokio-console`: Enable the `--tokio-console` option to start a Tokio console server on `http://127.0.0.1:6669/` for async inspection.
* `otlp`: Enable the `--trace-otlp` option to push traces to an OpenTelementry collector.

## Building and testing
Format, lint, build and test everything (I recommend creating a shell alias for this):
```sh
cargo fmt &&\
cargo clippy --all-features --all-targets &&\
cargo test --workspace --all-features --doc -- --nocapture &&\
cargo test --workspace --all-features --all-targets -- --nocapture &&\
cargo doc --workspace --all-features --no-deps
```
Check documentation coverage
```sh
RUSTDOCFLAGS="-Z unstable-options --show-coverage" cargo doc --workspace --all-features --no-deps
```
