## Install

```

npm install multisplice

```

## Usage

Renaming identifiers in Javascript code:

```js

var multisplice = require('./')

var dedent = require('dedent')

var astw = require('astw')

var src = dedent`

  function beep (boop) {

    boop *= baz

    console.log(boop)

  }

  var baz = 10

  beep(17)

`

var splicer = multisplice(src)

var renames = {}

var nextName = 'a'.charCodeAt()

astw(src)(function (node) {

  if (node.type === 'Identifier') {

    if (!renames[node.name]) renames[node.name] = String.fromCharCode(nextName++)

    splicer.splice(node.start, node.end, renames[node.name])

  }

})

console.log(splicer.toString())

```

```

function a (b) {

  b *= c

  d.e(b)

}

var c = 10

a(17)

```

## API

### `var s = multisplice(string)`

Create a string splicer instance. This instance will splice things into `string`.

### `s.splice(start, end, value)`

Replace the slice from indices `start` to `end` in the original string with `value`.

### `s.slice(start, end)`

Get a part of the spliced string, using indices `start` to `end` from the original string.

### `s.toString()`

Get the full spliced string (`.slice(0)`).
