OneClick-CP — One-click DSA & CP Starter Kit

A VS Code extension that sets up your coding sandbox in seconds, exports your solutions neatly, and gives you a growing snippets library — all without leaving the editor.

✨ Features

🚀 Reset Files

Quickly reset the 3 standard files in your workspace:

• main.cpp
• input.txt
• output.txt

Uses the selected template (see below). If any file is missing in the chosen template, a sensible default is used.

📤 Export Solution

Save your current main.cpp, input.txt, and output.txt into Solutions/<your-name>/.
Reads from the open editors first (so unsaved work is exported), then falls back to disk.

🔁 Export + Reset

One command to:

1. Export the current solution
2. Reset the three files with your selected template

Perfect for quick problem switching.

💾 Custom Templates

Save any combination of the three files as a reusable template.

• Create templates via the Sidebar → Save Template
• Delete templates via the Sidebar → Delete Template
• Templates are stored in VS Code settings under oneclick-cp.templates

📚 Snippets (Sidebar + Editor)

A curated snippet library for C++, Python, and Java. (Only C++ snippets are implemented currently. custom snippets can still be created for other languages)

• Browse by Category/Subcategory in the Sidebar
• Preview a snippet (inline "ghost" preview)
• Insert at the cursor location
• Create from Selection → Save highlighted code as a new snippet (auto-name collision handling; saved under Custom/<subcategory>.json)
• Built-in snippets are merged with your user snippets (user overrides on duplicate keys)

User snippets are stored under the extension’s global storage path:
<globalStorage>/snippets/<language>/Custom/<subcategory>.json

👉 Full list of built-in snippets is available here:

🧩 Arrange Layout

Closes all tabs and opens:

• main.cpp (left)
• input.txt (top-right)
• output.txt (bottom-right)

🧰 Commands & Shortcuts

• Reset Files → Ctrl + Alt + R (you can bind this yourself in Keyboard Shortcuts)

⸻ 🧯 Troubleshooting • Sidebar looks empty / styling off → Ensure HTML/CSS files are bundled (we fixed a webpack omission in v0.1.1). • Snippet preview not visible → Make sure an editor is active; preview shows as faint inline text. • Nothing resets → Confirm a workspace is open and the three files exist (fallback will write them to your first workspace). • Exported files missing changes → We read from open editors first; if none open, we read from disk.
