  3. zeal

    Offline documentation browser inspired by Dash

    Project mention: Self-Host and Tech Independence: The Joy of Building Your Own | news.ycombinator.com | 2025-06-07

    For offline documentation, I use these in order of preference:

    • Info¹ documentation, which I read directly in Emacs. (If you have ever used the terminal-based standalone “info” program, please try to forget all about it. Use Emacs to read Info documentation, and preferably use a graphical Emacs instead of a terminal-based one; Info documentation occasionally has images.)

    • Gnome Devhelp².

    • Zeal³

    • RFC archive⁴ dumps provided by the Debian “doc-rfc“ package⁵.
