# 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.
## 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 the `ziglings` script and follow the instructions to begin!
```bash
./ziglings
```
## Manual Usage
If you can't (or don't want to) use the script, you can manually verify each
exercise with the Zig compiler.
Some exercises need to be "run" (compiled and executed):
```bash
zig run exercises/01_hello.zig
```
Some exercises need to be tested:
```bash
zig test exercises/02_hello_test.zig
```
## TODO
Contributions are very welcome! I'm writing this to teach myself and to create
the learning resource I wished for. There will be tons of room for improvement:
* Wording of explanations
* Idiomatic usage of Zig
* Additional exercises
* Re-write the `ziglings` script using the Zig build system (???)
Planned exercises:
* [x] Hello world
* [ ] Hello tests
* [ ] Assignment
* [ ] Arrays
* [ ] If
* [ ] While
* [ ] For
* [ ] Functions
* [ ] Defer
* [ ] Errors
* [ ] Switch
* [ ] Runtime safety
* [ ] Unreachable
* [ ] Pointers
* [ ] Pointer sized integers
* [ ] Multi pointers
* [ ] Slices
* [ ] Enums
* [ ] Structs
* [ ] Unions
* [ ] Integer rules
* [ ] Floats
* [ ] Labelled blocks
* [ ] Labelled loops
* [ ] Loops as expressions
* [ ] Optionals
* [ ] Comptime
* [ ] Inline loops
* [ ] Anonymous structs
* [ ] Sentinel termination
* [ ] Vectors
* [ ] Imports
The initial topics for these exercises were unabashedly cribbed from
[ziglearn.org](https://ziglearn.org/).
