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

🚀 Multi-Language Support

Seamlessly switch between C++, Java, Python, and JavaScript. The extension automatically detects the language based on your active file or workspace structure.

🚀 Reset Files

Quickly reset the standard files in your workspace:

• main.cpp / Main.java / main.py / main.js
• 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 file, 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 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++, Java, Python, and JavaScript.

• Algorithms: Sorting, Searching (Binary Search), Graph (BFS, DFS, Dijkstra), DP (Knapsack, LCS), Math (GCD, Sieve), Backtracking.
• Data Structures: Segment Trees, Tries, Union Find, Fenwick Trees, Linked Lists, Trees.
• Utilities: Fast I/O, Comparators.

Functionality:

• 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

🧯 Troubleshooting

• Sidebar looks empty / styling off → Ensure HTML/CSS files are bundled.
• 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 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.
