How do I change until the next underscore in VIm?

Solution 1:

You can do cf_. f won't highlight the searched character.

You can also do ct_ if you don't want to include the _.

Solution 2:

Put this in your .vimrc:

set iskeyword-=_

Then _ will be treated as a word boundary (though not a WORD boundary), and cw could be used to just change "awesome", and cW to change the whole thing.

See:

:help iskeyword

and

:help word

for more info.

Solution 3:

camelcasemotion is a pretty handy vim plugin that allows you to move through words when using underscore or camelcase notation. Using this plugin you can place a comma in front of many of the traditional vim motion commands which will allow you to treat words in underscore or camelcase notation as full words.
