Reading epub in PC is pain as hell. I have tried a lot tool like calibre epubreader for better view experience. However, some of the pifalls always exist in one or another.

• Loading is slow because of the splitted file.
• No smooth scrolling.
• pdf generating is so ugly

So I wonder. I have a web browser like Chrome which is a natural epub reader. And we can install any plugin we want from google store. for example, I use vim binding a lot, how do we navigate in epub with vim binding by the power of vimium plugin.

So, the basic idea is converting epub to a big html. Simple but effective.

• Mac
• Windows

pip install epub2html
epub2html abc.epub  

will open your converted epub html file in browser .

use automator, generate the app, create a Run shell script module

source ~/.bash_profile
/usr/local/bin/epub2html "$1"

check which epub2html in your bash to make sure it's the right path. save it, link the file with this app, You are good to go.
