strip-filename-increment

Operating systems commonly add a trailing increment, or the word 'copy', or something similar to duplicate files. This strips those increments. Tested on Windows, MacOS, and Linux.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

Install

Install with npm (requires Node.js >=8):

$ npm install --save strip-filename-increment

Usage

const strip = require('strip-filename-increment');

API

strip

Remove trailing increments from the dirname and/or stem (basename without extension) of the given file path or object.

Params

• file {Sring|Object}: If the file is an object, it must have a path property.
• options {Object}: See available options.
• returns {String|Object}: Returns the same type that was given.

.increment

Removes trailing increments from the given string.

Params

• input {String}
• options {Object}: See available options.
• returns {String}

Example

console.log(strip.increment('foo (2)')); => 'foo'
console.log(strip.increment('foo (copy)')); => 'foo'
console.log(strip.increment('foo copy 2')); => 'foo'

.dirname

Removes trailing increments and returns the dirname of the given filepath.

Params

• filepath {String}
• options {Object}: See available options.
• returns {String}: Returns the dirname of the filepath, without increments.

Example

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

Removes trailing increments and returns the stem of the given filepath.

Params

• filepath {String}
• options {Object}: See available options.
• returns {String}: Returns the stem of the filepath, without increments.

Example

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

Removes trailing increments and returns the basename of the given filepath.

Params

• filepath {String}
• options {Object}: See available options.
• returns {String}: Returns the basename of the filepath, without increments.

Example

console.log(strip.basename('foo/bar (2).txt')); //=> 'bar.txt'
console.log(strip.basename('foo/bar (copy).txt')); //=> 'bar.txt'
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

Removes trailing increments from the dirname and stem of the given filepath.

Params

• filepath {String}
• options {Object}: See available options.
• returns {String}: Returns the basename of the filepath, without increments.

Example

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

Removes trailing increments from the dirname and stem properties of the given file.

Params

• filepath {String}
• options {Object}: See available options.
• returns {String}: Returns the basename of the filepath, without increments.

Example

console.log(strip({ path: 'foo copy/bar (2).txt' }));
//=> { path: 'foo/bar.txt', dir: 'foo', base: 'bar.txt', name: 'bar', ext: '.txt' }
console.log(strip({ path: 'foo (2)/bar (copy).txt' }));
//=> { path: 'foo/bar.txt', dir: 'foo', base: 'bar.txt', name: 'bar', ext: '.txt' }
console.log(strip({ path: 'foo (2)/bar copy 2.txt' }));
//=> { path: 'foo/bar.txt', dir: 'foo', base: 'bar.txt', name: 'bar', ext: '.txt' }
console.log(strip({ path: 'foo copy/bar (2) copy.txt' }));
//=> { path: 'foo/bar.txt', dir: 'foo', base: 'bar.txt', name: 'bar', ext: '.txt' }
console.log(strip({ path: 'foo copy/bar (2) - copy.txt' }));
//=> { path: 'foo/bar.txt', dir: 'foo', base: 'bar.txt', name: 'bar', ext: '.txt' }

Options

removeRawNumbers

Remove "raw" trailing numbers that might not actually be increments. Use this with caution.

Type: boolean

Default: undefined

Example:

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

console.log(strip('foo (1)'));  
console.log(strip('foo (2)'));  
console.log(strip('foo (22)')); 

All of the following would return foo.txt

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

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

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'));
