# 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 })
