## API
### [strip](index.js#L34)
Remove trailing increments from the `dirname` and/or `stem` (basename
without extension) of the given file path or object.

* `options` **{Object}**: See [available options](#options).
* `returns` **{String|Object}**: Returns the same type that was given.
### [.increment](index.js#L62)
Removes trailing increments from the given string.
**Params**
* `input` **{String}**
* `options` **{Object}**: See [available options](#options).
* `returns` **{String}**
**Example**
```js
console.log(strip.increment('foo (2)')); => 'foo'
console.log(strip.increment('foo (copy)')); => 'foo'
console.log(strip.increment('foo copy 2')); => 'foo'
```
### [.dirname](index.js#L86)
Removes trailing increments and returns the `dirname` of the given `filepath`.
**Params**
* `filepath` **{String}**
* `options` **{Object}**: See [available options](#options).
* `returns` **{String}**: Returns the `dirname` of the filepath, without increments.
**Example**
```js
console.log(strip.dirname('foo (2)/bar.txt')); => 'foo'
console.log(strip.dirname('foo (copy)/bar.txt')); => 'foo'
console.log(strip.dirname('foo copy 2/bar.txt')); => 'foo'
```
### [.stem](index.js#L107)
Removes trailing increments and returns the `stem` of the given `filepath`.
**Params**
* `filepath` **{String}**
* `options` **{Object}**: See [available options](#options).
* `returns` **{String}**: Returns the `stem` of the filepath, without increments.
**Example**
```js
console.log(strip.stem('foo/bar (2).txt')); //=> 'bar'
console.log(strip.stem('foo/bar (copy).txt')); //=> 'bar'
console.log(strip.stem('foo/bar copy 2.txt')); //=> 'bar'
console.log(strip.stem('foo/bar (2) copy.txt')); //=> 'bar'
console.log(strip.stem('foo/bar (2) - copy.txt')); //=> 'bar'
```
### [.basename](index.js#L128)
Removes trailing increments and returns the `basename` of the given `filepath`.
**Params**
* `filepath` **{String}**
* `options` **{Object}**: See [available options](#options).

console.log(strip.basename('foo/bar copy 2.txt')); //=> 'bar.txt'
console.log(strip.basename('foo/bar (2) copy.txt')); //=> 'bar.txt'
console.log(strip.basename('foo/bar (2) - copy.txt')); //=> 'bar.txt'
```
### [.path](index.js#L151)
Removes trailing increments from the `dirname` and `stem` of the given `filepath`.
**Params**
* `filepath` **{String}**
* `options` **{Object}**: See [available options](#options).
* `returns` **{String}**: Returns the `basename` of the filepath, without increments.
**Example**
```js
console.log(strip.path('foo copy/bar (2).txt')); //=> 'foo/bar.txt'
console.log(strip.path('foo (2)/bar (copy).txt')); //=> 'foo/bar.txt'
console.log(strip.path('foo (2)/bar copy 2.txt')); //=> 'foo/bar.txt'
console.log(strip.path('foo copy/bar (2) copy.txt')); //=> 'foo/bar.txt'
console.log(strip.path('foo copy/bar (2) - copy.txt')); //=> 'foo/bar.txt'
```
### [.file](index.js#L181)
Removes trailing increments from the `dirname` and `stem` properties of the given `file`.
**Params**

## Options
### removeRawNumbers
Remove "raw" trailing numbers that might not actually be increments. Use this with caution.
**Type**: `boolean`
**Default**: `undefined`
**Example**:
```js
console.log(strip('foo 1')); //=> 'foo 1'
console.log(strip('foo 1', { removeRawNumbers: true })); //=> 'foo'
console.log(strip('foo (1) 1')); //=> 'foo (1) 1'
console.log(strip('foo (1) 1', { removeRawNumbers: true })); //=> 'foo'
// This following example is not touched either way,
// since it's definitely not an increment.
console.log(strip('foo [1]')); //=> 'foo [1]'
console.log(strip('foo [1]', { removeRawNumbers: true })); //=> 'foo [1]'
```
## Examples
### Windows path increments
All of the following would return `foo`
```js
console.log(strip('foo (1)'));
console.log(strip('foo (2)'));
console.log(strip('foo (22)'));
```
All of the following would return `foo.txt`
```js
console.log(strip('foo (1).txt'));
console.log(strip('foo (2).txt'));
console.log(strip('foo (22).txt'));
```
### MacOS path increments
All of the following would return `foo`
```js
console.log(strip('foo copy'));
console.log(strip('foo copy 1'));
console.log(strip('foo copy 2'));
console.log(strip('foo copy 21'));
console.log(strip('foo copy 219 copy 219'));
```
All of the following would return `foo.txt`
```js
console.log(strip('foo copy.txt'));
console.log(strip('foo copy 1.txt'));
console.log(strip('foo copy 2.txt'));
console.log(strip('foo copy 21.txt'));
console.log(strip('foo copy 219 copy 219.txt'));
```
