So I have searched for it.
There’s Enlighter plugin which makes codes beautiful.
Before enable the plugin, looked plain text. And codes are always messed up. After publish, the new line disappeared and even codes are changed. Like this…
And after plugin enabled.
Looks cool, huh?
Also it provides plain text with popup and we can hide line number as well.
While I was searching for syntax highlighter plugin, I found WYSIWYG beautifier as well.
This makes edit text using text field a lot easier.
It shows like this.
What a colorful world!
