# ats-formatter

[![Build Status](https://travis-ci.org/vmchale/ats-format.svg?branch=master)](https://travis-ci.org/vmchale/ats-format)

This is a code formatter for [ATS](http://www.ats-lang.org/). It is
a work-in-progress, but it can handle a subset of the language already.

If you find something that's not listed in `TODO.md` feel free to open
an issue.

## Configuration

`atsfmt` is configured with the `.atsfmt.toml` file. As an example:

```toml
ribbon = 0.6 # maximum ribbon fraction
width = 120 # maximum width
clang-format = false # call clang-format on inline code
```

## Installation

The [releases](https://github.com/vmchale/ats-format/releases) page has binary
