Tie allows generation of Haskell server stubs from
[OpenAPI (v 3.x) specifications](https://swagger.io/specification/).

If you are looking for a generator for Haskell client code, check out the
[Haskell-OpenAPI-Client-Code-Generator](https://github.com/Haskell-OpenAPI-Code-Generator/Haskell-OpenAPI-Client-Code-Generator)
project.

## Installation

### Building from source

Below are the steps to install Tie using the Cabal build tool.

First, you need to clone the repository

```bash
$ git clone https://github.com/scarf-sh/tie.git
$ cd tie
```

Then, you need to build it using cabal:

```bash
$ cabal build exe:tie
```

Finally, you can copy the resulting executable to your desired location:

```bash
$ cp $(cabal exec -- which tie) ~/.local/bin/tie
```

Alternatively, instead of manually copying the executable you can install with
cabal:

```bash
$ cabal install .
```
