# metaline

A tiny language to write mapping functions as strings.

## Install

```bash

npm i metaline

```

## Example syntax

The string `where.id.in.$>#id;limit:99` generates the equivalent function of:

```js

function transform (input) {

  return {

    where: {

      id: {

        in: input.map((i) => i.id)

      }

    },

    limit: 99

  }

}

```

The string `$>id.#directoryId` generates the equivalent function of:

```js

function transform (input) {

  return input.map((t) => {

    return {

      id: t.directoryId

    }

  })

}

```

## Language Tokens

* `.` separate properties in an object

* `$` the input 

* `$>` loop over the input

* `#` access the following input property
