Make User Manual available for use offline

[Wilker-uwu]

Mentioned in #14640, part of a duplicate of #12867

The suggestion is that the extension should offer an option to make available the use of the User Manual of the extension itself fully offline. that would be helpful for me specially since i will be without internet very soon, and having the option to consult any manuals regardless of connection status is always a nice-to-have feature for this <3

As a low-tech option, can you save that page from the browser?

i'm able to download the whole repository for the manual, although i'm not sure how to build it since i've never dealt with Ruby before (or most languages in general aside from Java and Js+node for that matter), and every build i ever attempted from Source in my life before is always broken from the start lol (i'm sorry, i didn't mean to sound rude or anything x.x)

below is an attempt at building the manual from the repository. the other commands in the readme file also fails for the same error :(

Building is not going to be much fun. Browsers can save pages, including associated resources, so you would get a copy of the rendered manual.

[Wilker-uwu]

that i can do, yes

@Wilker-uwu Use ruby 2.7 Ref: https://github.com/rust-analyzer/rust-analyzer.github.io/blob/src/.github/workflows/ci.yml#L15

[Wilker-uwu]

@manthanrtilva not much luck with that either. :/

[lnicola]

Why are you trying to build it from source?

[Wilker-uwu]

thought would be the easiest way to get the whole thing and easily update later while i still have an internet connection

The easiest way is probably Ctrl-S in a browser.
