Resolve Tilde

Resolve Tilde is a quick and easy package to, well, resolve tildes. Tildes are the wavy symbols (~) that Dart can't naturally expand.

Notes

• This package is in beta and has not yet been universally tested.

Platform Support

Layout

Constants

• tilde: This is defined in the top level, so if the package is imported, you can simply reference tilde to get ~ as a String.
• Tilde.tilde: This is the exact same thing as the above constant, except it's a static member of the Tilde class.

Classes

Tilde: This is the main class for containing resources for resolving tildes.

• Static constant Tilde.tilde: Discussed above.
• Static String function Tilde.resolve: This function is what actually resolves the tildes.
  • You can pass an optional positional path parameter to specify the path to actually expand. The default is just a tilde.
  • Note that this function does not fully expand the path; it only expands the first tilde in the included path if that tilde is at the beginning of the path.
• Static String function Tilde.resolveOrNull: This function is the same as Tilde.resolve, but if a HomeDirectoryNotFoundException is thrown, then this function will catch it and return null. This would be generally better for safety, if you're fine with null checks.

Usage

Constants

import 'package:resolve_tilde/resolve_tilde.dart';

print(tilde);       // Output: '~'
print(Tilde.tilde); // Output: '~'

Resolving

import 'package:resolve_tilde/resolve_tilde.dart';

if (Platform.isWindows) {
    print(Tilde.resolve());                              // Output: 'C:\Users\user' or similar
    print(Tilde.resolveOrNull() ?? "No home dir found"); // Output: 'C:\Users\user', similar, or null
    print(Tilde.resolve("~\\AppData\\Local"));           // Output: 'C:\Users\user\AppData\Local'
} else if (Platform.isMacOS || Platform.isLinux) {
    print(Tilde.resolve());                              // Output: '/home/user' or similar
    print(Tilde.resolveOrNull() ?? "No home dir found"); // Output: '/home/user', similar, or null
    print(Tilde.resolve("~/Pictures/Screenshots"));      // Output: '/home/user/Pictures/Screenshots' or similar
}
