A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

How to write an awesome-wm config with Fennel

Awesome-WM is a X11 window manager, that is configured via Lua. Fennel is a Lisp for Lua. This shows a general setup of how to write your awesome-wm config using fennel directly without the compilation step (which would also work, but is not needed).

General setup

Fetch a recent Fennel version (the

The color range of a 256 color terminal consists of 4 parts, often 5, in which case you actually get 258 colors:

• Color numbers 0 to 7 are the default terminal colors, the actual RGB value of which is not standardized and can often be configured.
• Color numbers 8 to 15 are the "bright" colors. Most of the time these are a lighter shade of the color with index - 8. They are also not standardized and can often be configured. Depending on terminal and shell, they are often used instead of or in conjunction with bold font faces.
• Color numbers 16 to 231 are RGB colors. These 216 colors are defined by 6 values on each of the three RGB axes. That is, instead of values 0 - 255, each color only ranges from 0 - 5.

* One of the questions that recently came up is how to remove vowels from Hebrew characters in Unicode
* (or any other similar language). A quick look at Hebrew Unicode chart shows that the vowels are all
* located between 0x0591 (1425) and 0x05C7 (1479). With this and Javascript's charCodeAt function, it
* is trivial to strip them out with Javascript as follows
