leetui-terminal 0.4.0

Terminal-first LeetCode practice app powered by Textual

LeetUI (macOS-first Terminal LeetCode TUI)

A terminal-only LeetCode-style practice app built with Textual + Rich.

Install

pip install leetui-terminal

or

pip3 install leetui-terminal

Then run:

leetui

That's it. No virtual environment needed.

Requires: macOS (Terminal.app or iTerm2) with Python 3.10+

If you don't have Python: brew install python

Run from source (for contributors)

git clone https://github.com/siddartha018/leetcodecli.git
cd leetcodecli
python3 -m venv .venv
source .venv/bin/activate
pip3 install -e .
leetui

Always work inside the venv when developing. To re-enter it later:

cd leetcodecli
source .venv/bin/activate

Keyboard shortcuts (keyboard-only flow)

Problem browser:

• ↑ / ↓: Move between search, filters, and problem list
• ← / →: Move across filters
• Enter: Open selected problem in workspace
• Esc: Back to home

Workspace (split view):

• e: Focus the code editor (right pane)
• s: Toggle between Description and Solutions tabs (left pane)
• Esc: Editor → question pane → problem browser
• ↑ / ↓: Scroll description or navigate solutions list
• Ctrl+R / Alt+R: Run current test
• Ctrl+T / Alt+T: Run all tests
• Ctrl+D / Alt+D: Save solution
• PageUp / PageDown: Fast scroll
• Ctrl+Q: Quit app

Language support

• Current build is Python-only for writing and running code.
• Onboarding asks you to continue with Python before sheet selection.

Search and filters

Start screen includes:

• Free text search (title/tags/patterns/companies)
• Company filter
• Pattern filter
• Difficulty filter (easy, medium, hard)
• Source filter (leetcode, cses, web, local)

Sheets support

Included sheet catalog:

• NeetCode 150
• Striver DSA Sheet
• TLE Eliminators CP Sheet
• CSES Problem Set

The app shows local coverage as (<local>/<total>) per sheet.

To make these filters useful, include metadata in problem JSON:

{
  "source": "leetcode",
  "companies": ["amazon", "google"],
  "patterns": ["two-pointers", "hashmap"]
}

Adding questions from web / LeetCode

LeetUI reads local JSON files in leetui/problems/. To include web/LeetCode questions, export or curate them into this JSON format and set:

• "source": "leetcode" (or "web")
• "source_url": "<original problem URL>"
• "companies": [...]
• "patterns": [...]

This keeps the app terminal-only and fast while still supporting web-curated problem sets.

You can also import a JSON catalog directly:

leetui-import /path/to/catalog.json
# or
leetui-import https://example.com/leetui-catalog.json

Share with friends

Tell them to run:

pip install leetui-terminal
leetui

Or using pipx (isolated install):

brew install pipx
pipx ensurepath
pipx install leetui-terminal
leetui

Solutions page

Each problem has a read-only solutions page with:

• Brute Force explanation + Python code
• Better explanation + Python code
• Optimal explanation + Python code
