Archived: check out coerce.nvim

I no longer have to maintain my own solution because coerce.nvim is implemented in lua and as a result is much more extensible.

caser.vim

Easily change word casing with motions, text objects or visual mode.

This plugin is largely inspired by Tim Pope's vim-abolish, and aims to improve its casing functionality to better blend with Vim's editing philosophy.

Installation

vim-caser may be installed by any of your favourite plugin managers. Be it Pathogen, Vundle or Plug, use whichever you prefer.

For example, when using with Plug:

Plug 'arthurxavierx/vim-caser'

Usage

vim-caser makes it easy to convert between multiple word casings, from camelCase to snake_case to Title Case, it blends nicely with Vim's editing features such as motions, text objects and visual mode.

All mappings below must be followed by a motion or a text object, or be applied within visual mode.

Case	Default Mapping	Plug Mapping (normal/visual)
MixedCase or PascalCase	gsm or gsp	<Plug>CaserMixedCase/<Plug>CaserVMixedCase
camelCase	gsc	<Plug>CaserCamelCase/<Plug>CaserVCamelCase
snake_case	gs_	<Plug>CaserSnakeCase/<Plug>CaserVSnakeCase
UPPER_CASE	gsu or gsU	<Plug>CaserUpperCase/<Plug>CaserVUpperCase
Title Case	gst	<Plug>CaserTitleCase/<Plug>CaserVTitleCase
Sentence case	gss	<Plug>CaserSentenceCase/<Plug>CaserVSentenceCase
space case	gs<space>	<Plug>CaserSpaceCase/<Plug>CaserVSpaceCase
dash-case or kebab-case	gs- or gsk	<Plug>CaserKebabCase/<Plug>CaserVKebabCase
Title-Dash-Case or Title-Kebab-Case	gsK	<Plug>CaserTitleKebabCase/<Plug>CaserVTitleKebabCase
dot.case	gs.	<Plug>CaserDotCase/<Plug>CaserVDotCase

The gs prefix can be changed through the option g:caser_prefix. Alternatively, the default mappings can be disabled by setting g:caser_no_mappings.
