API
constructor
Setup a path
const path = new FilePath('this/is/a/file.jpeg');
path
Set: set up a path. Used in the constructor
Get: get the fully qualified path
const originalFile = new FilePath();
originalFile.path = '/this/is/a/file.jpeg';
console.log(originalFile.path);
> '/this/is/a/file.jpeg'
file
Set: set a file and extension
If the extension is missing, it will be undefined.
Get: get the file with the extension
const path = new FilePath('this/is/a/file.jpeg');
path.file = 'other.pdf'
console.log(path.file, path.filename, path.extension, path.path);
> 'other.pdf'
> 'other'
> 'pdf'
> 'this/is/a/other.pdf'
path.file = 'new';
console.log(path.file, path.filename, path.extension, path.path);
> 'new'
> 'new'
> undefined
> 'this/is/a/new'
dir
Set: change the directory (without the file)
Get: get the directory (without the file)
const path = new FilePath('this/is/a/file.jpeg');
path.dir = '/this/is/the'
console.log(path.dir, path.file, path.filename, path.extension, path.path);
> '/this/is/the'
> 'file.jpeg'
> 'file'
> 'jpeg'
> 'this/is/the/file.jpeg'
filename
Set: set the filename (without extension)
Get: get the filename (without extension)
const path = new FilePath('this/is/a/file.jpeg');
path.filename = 'new'
console.log(path.file, path.filename, path.extension, path.path);
> 'new.jpeg'
> 'new'
> 'jpeg'
> 'this/is/a/new.jpeg'
extension
Set: set the extension
Get: get the extension (does not include the .
delimiter)
const path = new FilePath('this/is/a/file.jpeg');
path.extension = 'png';
console.log(path.extension, path.file, path.path);
> 'png'
> 'file.png'
> 'this/is/a/file.png'
folders
An ordered array of folder names. folders[0] represents the root of the path. If absolute, it will be empty '' (required), if relative, it will be the first folder, or reference '.' or '..'.
The recommended use it to change a specific folder in the path, using the index.
const path = new FilePath('/this/is/a/file.jpeg');
console.log(path.folders);
> ['', 'this', 'is', 'a']
path.path = 'this/is/the/file.jpeg';
console.log(path.folders);
> ['this', 'is', 'the']
path.folders.unshift('..');
path.folders[path.folders.length - 1] = 'relative';
console.log(path.folders, path.path);
> ['..', 'this', 'is', 'relative']
> '../this/is/relative/file.jpeg'
isAbsolute and isRelative
Booleans indicating if the path is absolute or relative. Absolute paths start with '/',
and path.folders[0] === ''
;
const path = new FilePath('/this/is/a/file.jpeg');
console.log(path.isAbsolute, path.isRelative)
> true
> false
path.path = 'this/is/a/file.jpeg';
console.log(path.isAbsolute, path.isRelative)
> false
> true
path.path = './this/is/a/file.jpeg';
console.log(path.isAbsolute, path.isRelative)
> false
> true
path.path = '../this/is/a/file.jpeg';
console.log(path.isAbsolute, path.isRelative)
> false
> true
