Architecture

Three-module CLI tool that wraps yt-dlp to download X/Twitter Space recordings as MP3:

• src/main.py — Click CLI entry point (cli). Validates URL via validator, then delegates to downloader. Registered as x-space-dl console script.
• src/validator.py — validate_space_url() returns (is_valid, space_id, error_message) tuple. Accepts both x.com and twitter.com domains.
• src/downloader.py — download_space() configures yt-dlp with bestaudio/best format and FFmpeg MP3 postprocessor. Output files are named space_{SPACE_ID}.mp3. Raises DownloadError on failure.

Tests mock yt_dlp.YoutubeDL — no network calls in unit tests. Integration tests use the @pytest.mark.integration marker.

Dependencies

Runtime: yt-dlp, click. System: ffmpeg. Dev: pytest, pytest-mock.
