Ask HN: Where do I find good code to read?
I've met a few young programmers who heard somewhere that object-oriented programming was bad and they want to get the enlightenment of functional programming that they've heard about. Frequently they travel from job to job like itinerant martial artists always looking for somewhere where they practice the true technique but they always seem disappointed as it is just as easy if not easier to screw up handling errors with monads than it is with exceptions and they find analogies like "a monad is like a burrito" just get them more confused.
As for something profound I'd point you to
https://github.com/cerner/clara-rules
which many people will struggle with because like many other production rules engines in LISP (and many other examples of simple compilers), there is hardly any code! Contrast that to the orders of magnitude larger rules engine Drools
https://github.com/kiegroup/drools
which is so crazy-complicated primarily because the Drools language is Java-based so you need all sorts of things that Clara or CLIPS don't need.

Helix: Release 24.03 Highlights
Helix's modal editing is based on Kakoune's modal editing which is like an evolution to Vim's modal editing. You can think of it as being always in selection (visual) mode. https://github.com/mawww/kakoune?tab=readme-ov-file#selectio...

A tutorial for the Sam command language (1986) [pdf]
And while it doesn’t use the sam language precisely, I think in the broader “postfix Vi with visual feedback” category Kakoune[1] also warrants mentioning. The command language, in my experience, feels much more logical than that of Vis coming from a blank slate (things might be different if you come from Vim, but even when I used Vim regularly I never used the editing language that much exactly because I could never remember the damn thing).
And having mentioned Kakoune it’d probably be unfair to then not mention Helix[2]. It has a very similar editing language, but it’s a fairly anti-Unix everything-bolted-in affair on the inside (“everything works out of the box” being the advertising take) compared to Kakoune’s Acme-inspired no-scripting scripting (there’s an ex-style command to exec a user program that can then drive the editor over stdio RPC, a set of hooks, and that’s it). So if you’ve come for the Plan 9 feels, I don’t expect Helix to be that appealing. It’s still a good editor, nevertheless.

What is the best book for complete beginner?
You can take a look at kakoune. The source code (excluding documentations, test cases, customizations etc.) is less than 40k. It is, IMHO, a show case of a C++ project in use.

Yes.

Not very motivated for such a harsh critic..

Understanding the Origins and the Evolution of Vi and Vim
I've been using Vim for years, but if there was one thing I could change, it would be the verb-noun order. The Kakoune[1] editor behaves mostly like Vim, but where Vim has `dw` as "delete word", Kakoune has it backwards: `wd`.
It might sound minor, but by placing the range first, Kakoune can give a preview of what will be changed. The longer or more complicated the command, the more this feature shines.
Strictly better as far as I know. A shame my muscle memory, and all default installations, are still stuck with Vim.

Helix editor: Make HTTP requests and insert JSON
Helix is a postmodern text editor built in Rust built for the terminal. It is inspired by Kakoune, another Rust based text editor. Helix has got multiple selections, built-in Tree-sitter integration, powerful code manipulation and Language server support.
