doc2dash is an MIT-licensed extensible Documentation Set generator intended to be used with the Dash.app API browser for macOS or one of its many free clones for all relevant platforms.
If you’ve never heard of Dash.app and its likes, you’re missing out: together with doc2dash it’s all your API documentation at your fingertips – even when you're offline!
doc2dash’s documentation lives at Read the Docs, the code on GitHub. It’s tested on Python 3.7 (the fully functional 2.x release line on PyPI also supports Python 2.7, 3.4–3.6, and PyPy). Both Linux and macOS are tested although certain features are only available on macOS.
