# 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
|
|
```
