Indenting code


Vim provides == and = as tools to aide in keeping your code formatted and tidy. Double equal can be used to quickly properly indent the current line. Similarly, 10== will indent 10 lines, inclusive of the one you’re one.

Consider this Ruby method, painful to look at it because the indentation is all over the place:

def longest(strings)

With our cursor on the d in def, we want to change this method into:

def longest(strings)

There are a few options to achieve the same result:

  • 4== will indent the current line, and the next three.
  • =ap will indent Around the current Paragraph. Having no empty lines, this method qualifies as a paragraph.
  • =% will indent to the the end of the method. Note this implies the use of the matchit plugin. But % works with common curly brace blocks, parens, etc out of the box.
  • V3j= will do a visual select on the current line and the three below and apply indenting to them.

These cover a lot of ground when trying to keep your code tidy.

Lastly, the nuclear option gg=G can be used to indent an entire file.
