path/winpath

Windows-style path manipulation that works on any platform.

Installation

go get github.com/therootcompany/golib/path/winpath

Usage

import winpath "github.com/therootcompany/golib/path/winpath"

// Clean a Windows path (from any platform)
clean := winpath.Clean(`C:\foo\..\bar`)  // C:\bar

// Join path elements
joined := winpath.Join(`C:\`, "foo", "bar.txt")  // C:\foo\bar.txt

// Split path into directory and file
dir, file := winpath.Split(`C:\foo\bar.txt`)  // C:\foo\, bar.txt

// Get file extension
ext := winpath.Ext(`C:\foo\bar.txt`)  // .txt

// Get base name
base := winpath.Base(`C:\foo\bar.txt`)  // bar.txt

// Get directory
d := winpath.Dir(`C:\foo\bar.txt`)  // C:\foo

// Check if path is absolute
winpath.IsAbs(`C:\foo`)      // true
winpath.IsAbs(`foo\bar`)     // false
winpath.IsAbs(`\foo`)        // false (rooted but no drive)
winpath.IsAbs(`\\server\share`)  // true (UNC)

// Get volume name
vol := winpath.VolumeName(`C:\foo\bar`)  // C:
len := winpath.VolumeNameLen(`C:\foo`)    // 2

// Convert separators
fwd := winpath.ToSlash(`C:\foo\bar`)   // C:/foo/bar
bck := winpath.FromSlash(`C:/foo/bar`) // C:\foo\bar

// Constants
winpath.Separator      // '\'
winpath.ListSeparator  // ';'
winpath.IsPathSeparator('\\')  // true
winpath.IsPathSeparator('/')   // true

Comparison with stdlib

Feature	`path/filepath`	`path/winpath`
Platform aware	Yes (uses OS)	No (always Windows)
Use alongside `filepath`	N/A	✅ Works together

Use path/filepath for native OS paths on any platform. Use path/winpath when you need to handle Windows paths on non-Windows platforms (e.g., parsing config files, cross-platform tools).
