A library that parses and validates rules from `robots.txt`.

## Installation

This library is available on [hex.pm](https://hex.pm/packages/robots).

To install this library, simply add the following lines to your

`rebar.config`:

```erlang

{robots, "1.1.1"}

```

## Usage

```erlang

Content = <<"User-Agent: bot\nAllow: /fish">>,

%% This will return an opaque type that contains all the rules and their agents

{ok, RulesIndex} = robots:parse(Content, 200),

true = robots:is_allowed(<<"bot/1.0.0">>, <<"/fish/salmon.html">>, RulesIndex),

true = robots:is_allowed(<<"bot/1.0.0">>, <<"/Fish.asp">>, RulesIndex),

```

## Development

### Running all the tests and linters

You can run all the tests and linters with the `rebar3` alias:

```sh

rebar3 check

```
