iota9star / export.dart
Last active September 17, 2024 10:22
Quickly create export files for all directories. Why are export files needed? To reduce the number of imports at the top of files and improve the Dart library import experience.
import 'dart:convert';
import 'dart:io';
import 'package:path/path.dart' as path;
Future<void> main() async {
final root = Directory.current;
final lib = Directory(path.join(root.path, 'lib'));
final projectName = await getProjectName(root);
createExport(lib, lib, fileName: projectName, skipChildren: true);

Created May 6, 2024 05:03 — forked from 0xjac/private_fork.md
Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.) 
    

    2. 



git clone --bare [email protected]:usi-systems/easytrace.git
