# 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 }
