How do I quickly comment and uncomment code with vim-commentary?

Explanation

vim-commentary by Tim Pope provides a simple way to toggle comments. It detects the correct comment syntax based on the file type.

How it works

• gcc toggles commenting on the current line
• gc{motion} toggles comments over a motion
• gcip toggles comments on the current paragraph
• gc in visual mode toggles comments on the selection

Example

In a Python file:

def hello():
    print("hello")

gcc on the print line comments it: # print("hello") gcc again uncomments it.

Tips

• Install: Plug 'tpope/vim-commentary'
• Automatically detects comment syntax per filetype
• gcgc uncomments a block of adjacent comments
• Works with counts: 3gcc comments 3 lines
• :set commentstring=//\ %s sets the comment format
