zibra

This repo holds my Zig code for the browser implemented in Web Browser Engineering.

Usage

You'll need Zig installed.

Clone the project

git clone https://github.com/braheezy/zibra.git

To build the project, run:

zig build
cp zig-out/bin/zibra .

zibra takes one or more URLs and displays the result in raw text on the command line.

> zibra https://example.org

Supported Features

zibra is small but supports the basics:

• HTTP/1.1
• HTTPS
• file:// URIs
• data: URIs
• Entity support (<div&gt becomes <div>)
• view-source:
• Connections that live beyond single request for Connection: keep-alive header
• Redirects
• Cache-Control header
• Content-Encoding: gzip and Transfer-Encoding: chunked headers

Development

There's more Zig commands:

# build and run
zig build run -- https://example.com
# Run rests
zig build test

To test chunked gzip responses, run gzipServer.py locally.

Known Issues

• On Mac, the content is stretched while the window is being resized. Apparently this is known behavior in SDL2 because Mac blocks the main thread while the mouse is being held down to resize windows, preventing SDL from rendering the content properly...I think.
