  • .github/workflows/: Contains automation scripts for CI/CD.
  • README.md: Contains project description and auto-generated stats.

🔧 Setup: Auto Submit and Move

To automate Kattis submissions and organize accepted files:

🛠️ Steps

  1. Install Prerequisites:

    • Python: Download Python
    • Kattis CLI: Kattis CLI
    • Python Packages: pip install requests beautifulsoup4
    • Ensure you have a valid .kattisrc file in your home directory with your credentials. You can get it from here.

  2. Add submit_and_move.py:

  3. Configure VSCode Task: Add this to .vscode/tasks.json:

    {
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Submit to Kattis",
      "type": "shell",
      "command": "python",
      "args": ["${workspaceFolder}/scripts/submit_and_move.py", "${file}"],
      "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": true,
        "panel": "shared",
        "showReuseMessage": false,
        "clear": false,
        "close": true
      },
      "problemMatcher": []
    }
  ]
}

  4. Setup Keybinding: Add to keybindings.json:

    [
  {
    "key": "numpad0",
    "command": "workbench.action.tasks.runTask",
    "args": "Submit to Kattis",
    "when": "editorTextFocus"
  }
]

  5. Create solutions Folder: Manually create the folder or the script will create it automatically.

  6. Submit Solution:

    • Keep unfinished solutions in the root directory. Open the solution file (e.g., kattisexercise.cpp), press numpad0, and it will automatically upload the solution to Kattis. If accepted, the script moves the file to the solutions folder.

🔧 Setup: Auto-Create Problem Set

Automate the creation of problem sets using Competitive Companion. You can add it as a Google Chrome extension from the Chrome Web Store here.

🔧 Setup: Folding for Template Files

  1. Install the Extension:
    Download the Auto Region Folder extension.

  2. Configure Settings:
    Add this to your settings.json to enable import folding by default:

    "editor.foldingImportsByDefault": true

    Now the template.cpp file will automatically fold the imports and core library definitions for a cleaner view.

🔧 Setup: Auto CPH Judge with Competitive Companion

  1. Install Competitive Companion extension for Google Chrome.

  2. Configure settings.json:

    "cph.general.defaultLanguage": "cpp",
"cph.general.defaultLanguageTemplateFileLocation": "C:\\Users\\simon\\dev\\GitHub\\competetive-programming\\templates\\template.cpp"

  3. Usage: Automatically fetch problems and use your custom C++ template.
