# lines-and-columns
Maps lines and columns to character offsets and back. This is useful for parsers
and other text processors that deal in character ranges but process text with
meaningful lines and columns.
## Install
```
$ npm install [--save] lines-and-columns
```
## Usage
```js
import { LinesAndColumns } from 'lines-and-columns'
const lines = new LinesAndColumns(
`table {
border: 0
}`
)
lines.locationForIndex(9)
// { line: 1, column: 1 }
lines.indexForLocation({ line: 1, column: 2 })
// 10
```

## API
### parseJson(string, reviver?, filename?)
Throws a `JSONError` when there is a parsing error.
#### string
Type: `string`
#### reviver
Type: `Function`
Prescribes how the value originally produced by parsing is transformed, before being returned. See [`JSON.parse` docs](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Using_the_reviver_parameter
) for more.
#### filename
Type: `string`
Filename displayed in the error message.
### parseJson.JSONError
Exposed for `instanceof` checking.
#### fileName
Type: `string`
The filename displayed in the error message.
#### codeFrame
Type: `string`
The printable section of the JSON which produces the error.
