# ziglings
|
|
|
|
Welcome to `ziglings`! This project contains a series of incomplete exercises.
|
|
By completing the exercises, you learn how to read and write
|
|
[Zig](https://ziglang.org/)
|
|
code.
|
|
|
|
This project was directly inspired by the brilliant and fun
|
|
[rustlings](https://github.com/rust-lang/rustlings)
|
|
project for the [Rust](https://www.rust-lang.org/) language.
|
|
|
|
## Intended Audience
|
|
|
|
This will probably be difficult if you've _never_ programmed before.
|
|
But no specific programming experience is required. And in particular,
|
|
you are _not_ expected to have any prior experience with "systems programming"
|
|
or a "systems" level language such as C.
|
|
|
|
Each exercise is self-contained and self-explained. However, you're encouraged
|
|
to also check out these Zig language resources for more detail:
|
|
|
|
* https://ziglearn.org/
|
|
* https://ziglang.org/documentation/master/
|
|
|
|
## Getting Started
|
|
|
|
_Note: This currently uses a shell (Bash) script to automate the "game". A
|
|
future update may remove this requirement. See TODO below._
|
|
|
|
Install the [master release](https://ziglang.org/download/) of the Zig compiler.
|
|
|
|
Verify the installation and version of `zig` like so:
|
|
|
|
```bash
|
|
$ zig version
|
|
0.7.1+<some hexadecimal string>
|
|
```
|
|
|
|
Clone this repository with Git:
|
|
|
|
```bash
|
|
git clone https://github.com/ratfactor/ziglings
|
|
cd ziglings
|
|
```
|
|
|
|
Then run `zig build` and follow the instructions to begin!
|
|
|
|
```bash
|
|
zig build
|
|
```
|
|
|
|
## Manual Usage
|
|
|
|
If you want to run a single file for testing, you can do so with this command:
|
|
|
|
```bash
|
|
zig run exercises/01_hello.zig
|
|
```
|
|
or, alternatively
|
|
```bash
|
|
zig build 01_test
|
|
```
|
|
|
|
To verify a single file, use
|
|
|
|
```bash
|
|
zig build 01_only
|
|
```
|
|
|
|
To prepare an executable for debugging, install it to zig-cache/bin with
|
|
|
|
```bash
|
|
zig build 01_install
|
|
```
|
|
|
|
## TODO
|
|
|
|
Contributions are very welcome! I'm writing this to teach myself and to create
|
|

|
|
|
|
* Wording of explanations

The initial topics for these exercises were unabashedly cribbed from
|
|
[ziglearn.org](https://ziglearn.org/). I've since moved things around
|
|
in an order that I think best lets each topic build upon each other.
