# The Oxlip API Language

Oxlip is a high-level functional programming language for designing [OpenAPI](https://www.openapis.org/what-is-openapi) definitions.

As an [Interface Description Language](https://en.wikipedia.org/wiki/Interface_description_language), it is not general purpose.

The motivation is to alleviate the pain of managing OpenAPI in JSON or YAML by hand and at scale.

Oxlip defines algebraic abstractions over [REST](https://en.wikipedia.org/wiki/Representational_state_transfer) concepts, not too dissimilar to [Sass/SCSS over CSS](https://sass-lang.com/).

There are pros and cons to both _API-design-first_ and OpenAPI generated from implementation.

As OpenAPI is better produced or consumed by machines rather than humans, Oxlip tries to help _API-design-first_ teams with better tooling.

## [Documentation](https://www.oxlip-lang.org/)

## [Playground](https://oxlip-lang.github.io/oxlip-playground)

## Installation

This step requires a [local Rust and Cargo installation](https://doc.rust-lang.org/cargo/getting-started/installation.html).

```

make install

```

Optional: a [VSCode language extension](https://github.com/oxlip-lang/oal-vscode) is available for syntax highlighting and IDE capabilities.

## Usage

```

    oal-cli [OPTIONS]

OPTIONS:

    -b, --base         The relative URL to a base OpenAPI description

    -c, --conf       The path to the configuration file

    -h, --help               Print help information

    -m, --main         The relative URL to the main program

    -t, --target     The relative URL to the target OpenAPI description

```

### Compiling the example program

```

oal-cli --conf examples/oal.toml

```

## Experimental: WebAssembly support

Release to WebAssembly requires the installation of [`wasm-pack`](https://rustwasm.github.io/wasm-pack/installer/).

```

make wasm

```
