This project is based on [mattnite/zig-zlib](https://github.com/mattnite/zig-zlib). I also used [LukasKastern]([Title](https://github.com/LukasKastern/zig-zlib) fork for making project compatibile with 0.11 zig master.

There is existing deflate/gzip compressor/decompressor in zig standard library. For using it in websocket implementation I was missing ability to set window size (it is fixed on 32k) and sliding window functionality in decompressor.
|
|
It seams that most other websocket implementations are using zlib for deflate.

### Link
|
|
There is empty zig project (made with 'zig init-exe') in [example/exe](example/exe) which illustrates how to link zlib library using zig package manager.
|
|
|
|
Add dependency in build.zig.zon:
|
|
```zig
|
|
.dependencies = .{
|
|
.zlib = .{
|
|
.url = "https://github.com/ianic/zig-zlib/archive/9186b0f5fdfd6c29cd04f7ada7b0113fe1f63611.tar.gz",
|
|
.hash = "122001cc3da638f9315f08fb51fe5aace68c254b59bcac3457e20d746565bad7fe04",
|
|
},
|
|
},
|
|
```
|
|
In build.zig link 'z' library and 'zlib' module:
|
|
```zig
|
|
// Link z library and zlib module.
|
|
exe.linkLibrary(b.dependency("zlib", .{
|
|
.target = target,
|
|
.optimize = optimize,
|
|
}).artifact("z"));
|
|
exe.addModule("zlib", zlib.module("zlib"));
|
|
```
|
|
|
|
|
|
### Notes
|
|
|
|
get zlib source into zlib folder:
|
|
```sh
|
|
wget https://github.com/madler/zlib/releases/download/v1.2.13/zlib-1.2.13.tar.gz
|
|
tar xvf zlib-1.2.13.tar.gz
|
|
rm zlib-1.2.13.tar.gz
|
|
mv zlib-1.2.13 zlib
|
|
``` |
