qtchan is a 4chan browser written with qt5.\ I started developing it because browsers suck.\ There's still a lot to do.

Features

browse and post on 4chan
auto update threads and auto download original file
download all media as original filename
tree style tabs and save state (./session.txt)
open files in OS's default application
search and filter
filter by regexp$options
self-archive
(You)

Build Instructions (Linux/BSD based)

needs qt5 with headers, qmake, and a compiler (like g++ or clang++)\ e.g. on Debian/Ubuntu: sudo apt install qt5 qt5-devel qt5-qmake make gcc\ For a clang build, change qmake ../ to qmake ../ -spec linux-clang

git clone https://github.com/siavash119/qtchan 
cd qtchan
mkdir build
cd build
qmake ../
make
./qtchan

Archlinux:

makepkg --install

or from AUR:

packer -S qtchan

Captcha

in the post form, focus the bottom lineEdit. It will load the challenge image
it's a grid following the numpad:
- 7 8 9
- 4 5 6
- 1 2 3
type in the numbers and hit enter (e.g. 034)
if it says "Verified.", you're good to post.
- Your code will expire in 2 minutes. If you want to load a new captcha, hit enter in the lineEdit or click the image.

Note: the numbers in this image follow a previous captcha number grid, the correct answer would be 893 in any order. qtchan captcha
