fullpath static method

String fullpath(String name)

Returns the full name of the path if possible.

Resolves the following segments:

• Segments '.' indicating the current directory
• Segments '..' indicating the parent directory
• Leading '~' character indicating the home directory
• Environment variables in IEEE Std 1003.1-2001 format, eg. $HOME/dart-sdk

Useful when you get path name in a format incompatible with POSIX, and intend to use it as part of the wildcard patterns.

Do not use this method directly on wildcard patterns because it can deform the patterns.

Implementation

static String fullpath(String name) {
  if (name.startsWith('..')) {
    final path = Directory.current.parent.path;
    if (name == '..') {
      name = path;
    } else if (name.startsWith('../')) {
      name = pathos.join(path, name.substring(3));
      name = pathos.normalize(name);
    } else {
      name = pathos.normalize(name);
    }
  } else if (name.startsWith('.')) {
    final path = Directory.current.path;
    if (name == '.') {
      name = path;
    } else if (name.startsWith('./')) {
      name = pathos.join(path, name.substring(2));
      name = pathos.normalize(name);
    } else {
      name = pathos.normalize(name);
    }
  } else {
    name = pathos.normalize(name);
  }

  name = FilePath.expand(name);
  if (_isWindows) {
    name = name.replaceAll('\\', '/');
  }

  return name;
}
