Path format convert

path-format-convert · version 1.0.0 · File paths (lexical) · free, no key needed

Convert file paths between POSIX and Windows formats, handling slashes, drive letters, and roots lexically.

Use when you need to: path format convert · posix to windows path · windows to posix path.

Supported

• path format convert
• posix to windows path
• windows to posix path
• path separator convert

Not supported

• stat file
• resolve symlinks
• filesystem access
• add drive letter

Behavior

• posix->windows: replace / with \, prepend \ if starts with / making it a rooted-but-driveless Windows path. windows->posix: replace \ with /, drive letter C:\ becomes /c/ (lowercase), UNC \\server\share -> //server/share. Does not resolve . or .. further. changed:false when input is already in target format.

Input

• path (string, required): min length 1; max length 4096
• to (one of "posix", "windows", required)
• from (one of "posix", "windows", "auto", optional)

Output

• converted (string, required)
• from (string, required)
• to (string, required)
• changed (boolean, required)

Limits

• max path bytes: 4096

Example

Request input:

{
  "path": "/usr/local/bin",
  "to": "windows"
}

Response:

{
  "result": {
    "converted": "\\usr\\local\\bin",
    "from": "posix",
    "to": "windows",
    "changed": true
  }
}
