📅🔒 Javascript/Typescript parser for OpenStreetMap [conditional restrictions](https://osm.wiki/Conditional_restrictions).

## Install

```sh

npm install osm-conditional-restrictions

```

## Usage

```js

import { parseConditionalRestrictions } from 'osm-conditional-restrictions';

const tags = {

  access: 'no',

  'access:conditional': 'yes @ (09:00-17:00 ; weight < 3.5)',

};

const output = parseConditionalRestrictions('access', tags);

// `output` will be an object that looks like this:

({

  default: 'no',

  exceptions: [

    {

      value: 'yes',

      if: {

        type: 'LogicalOperator',

        operator: 'OR',

        children: [

          { type: 'Condition', string: '09:00-17:00' },

          { type: 'Condition', string: 'weight < 3.5' },

        ],

      },

    },

  ],

});

```

## Scope

This library doesn't try to parse the conditional values, such as `09:00-17:00`.

To parse the [opening hours syntax](https://osm.wiki/Key:opening_hours), check out the [opening_hours](https://npm.im/opening_hours) library.
