path-interop

Provides path format conversion between Windows and Linux including path seperator conversion and environment variable expansion.

Allows you to add Linux path format interoperability into your Windows/Linux cross-platform apps.

Install

npm install --save path-interop

Usage

// Single instance
const PathInterop = require('path-interop');

// When multiple instances are required, use clone()
const interop1 = require('path-interop');
const interop2 = interop1.clone();

Functions

windowsToLinux(path, expand)

Converts path format from Windows to Linux with/without environment variable expansion.

Specify true for expand in order to expand environment variables like %VAR%.

Otherwise, variable names are preserved. For example, windowsToLinux('%USERPROFILE%/') will return '~/' without expansion.

NOTE: Windows Drive letter and colon (C:) is not convertible to Linux format. Therefore, by default it is preserved. For exmaple, windowsToLinux('C:\\') returns 'C:/'. You can change this behavior by using driveLetterConverter option.

linuxToWindows(path, expand)

Converts path format from Linux to Windows with/without environment variable expansion.

Specify true for expand in order to expand environment variables like ~/, $VAR or ${VAR}.

Otherwise, variable names are preserved. For example, linuxToWindows('~/') will return '%USERPROFILE%/' without expansion.

NOTE: ~otherUserName/ is unsupported

toLinux(path, expand)

Forcely converts path format to Linux with/without environment variable expansion.

Equivalent to windowsToLinux(linuxToWindows(path), expand).

toWindows(path, expand)

Forcely converts path format to Windows with/without environment variable expansion.

Equivalent to linuxToWindows(windowsToLinux(path), expand).

toSystem(path, expand)

Forcely converts path format to current platform. If process.platform is win32 internally calls toWindows, otherwise calls toLinux.

Options

driveLetterConverter

Specify converter function to convert drive letter.

// Default value (Preserve)
PathInterop.driveLetterConverter = letter => {
  return letter + ':'
}

// For MSYS2 (C:\ => /c)
PathInterop.driveLetterConverter = letter => {
    return '/' + letter.toLowerCase(); 
}

// Just only remove drive letter and colon
PathInterop.driveLetterConverter = letter => {
  return '';
}

caseInsensitivePlatforms

Array of platform name that store case-insensitive variable name like Windows. Return values of process.platform() are used.

// Default value
PathInterop.caseInsensitivePlatforms = [ 'win32' ];

// Custom additional value
PathInterop.caseInsensitivePlatforms.push('futurePlatform');

// Custom value
PathInterop.caseInsensitivePlatforms = [ 'win32', 'futurePlatform' ]

linuxEnvToWindowsEnv

Object that represent conversion table of environment variable name (Linux to Windows).

// Default value
PathInterop.linuxEnvToWindowsEnv.HOME = 'USERPROFILE';

// Custom additonal value
PathInterop.linuxEnvToWindowsEnv.LINUXENV = 'WINENV';

// Custom overwrite
PathInterop.linuxEnvToWindowsEnv = { LINUXENV: 'WINENV' };

windowsEnvToLinuxEnv

Object that represent conversion table of environment variable name (Windows to Linux).

// Default value
PathInterop.windowsEnvToLinuxEnv.USERPROFILE = 'HOME';

// Custom additonal value
PathInterop.windowsEnvToLinuxEnv.WINENV = 'LINUXENV';

// Custom overwrite
PathInterop.windowsEnvToLinuxEnv = { WINENV: 'LINUXENV' };

clone

Creates a new object that is a copy of the current instance.

var p1 = require('path-interop');
var p2 = require('path-interop');

console.log(p1 === p2); // True (Because of require-cache)

var p3 = p1.clone();

console.log(p1 === p3); // False
console.log(p1.linuxEnvToWindowsEnv 
  === p3.linuxEnvToWindowsEnv); // False
