devdocs.el VS zeal

emacs integration: https://github.com/astoff/devdocs.el

devdocs.el: Documentation reader with quick and handy lookup commands. It is similar to the built-in Info reader, but has a different (likely larger) document coverage.

I use this (https://github.com/astoff/devdocs.el) emacs package to download devdocs locally and access them from emacs, which is pretty great.

Support for other languages is a good point. Most don't ship info documentation. :P If you want something inside a normal Emacs buffer rather than a separate browser-like application, maybe you'd enjoy devdocs.io and astoff's devdocs.el package.

+1. I'm using an amazing Emacs package that treats DevDocs kinda like Dash: https://github.com/astoff/devdocs.el

info-like: https://github.com/astoff/devdocs.el

devdocs.el to read documentation

Wow, so many devdocs packages! Of the two I mentioned, devdocs-browser is the one in the emacs-devdocs-browser repo you found. But the other one I was thinking of didn't turn up in your search: devdocs. I wasn't aware of the others you found, probably because they aren't on GNU ELPA or on MELPA.

There's also Zeal (https://zealdocs.org/) which is basically the same as Dash but open source and runs on non-Mac devices.

For offline tech documentation you can use Zeal. Must have tool for poor internet connection places. Present in ubuntu repos. https://zealdocs.org/

ads don't have to proprietary

here's one example of ads in FOSS https://github.com/zealdocs/zeal/issues/779

There’s stuff like https://zealdocs.org/ that allow you to take all relevant documentation with you so offline coding will work.

If you just want to be productive, you could also bring a lot of books or downloaded tutorials on a drive.

Btw, make sure your drive is encrypted and you think of a way to backup your data so you don’t lose the offline progress.

I’d suggest you look into Kiwix¹ and also Zeal².

For offline documentation, I use Zeal (called Dash on macos) which looks/works almost identically to rubydoc.info but much faster since it's offline, has a standard interface for all installed language documentations, and only 1 global hotkey away while programming.

I highly recommend using local solutions to this local issue: Zeal[1] (aka Dash[2] on MacOS)

Load up the "docsets" of your languages (lightly edited HTML docs for indexing purposes) and use a global keyboard shortcut (F8 for me) to pull up Python/Postgres/Terraform docs, searching for the right function without internet query.

This isn't straight up applicable to all questions of course, but "How do I search regular expressions in Python again?" is now as easy as "re"

Note that the docsets can be converted from normal HTML ones via doc2dash[3], especially useful to load up custom docs like private providers.
