Priview almost everything with QuickLook plugins for macOS
Out of the box Finder’s QuickLook is quite limited, particularly for developer.
But we can easly change that, using QuickLook plugins.
We don’t want to fall asleep while drag and drop installing all this plugins right ?
So first we install Homebrew.
Then we install plugins with just this one command
brew cask install qlcolorcode qlstephen qlmarkdown quicklook-json qlprettypatch quicklook-csv betterzipql qlimagesize webpquicklook suspicious-package quicklookase qlvideo
