COMMANDS                                                   *colorizer-commands*

|:ColorizerAttachToBuffer|                             *:ColorizerAttachToBuffer*

Attach to the current buffer and start highlighting with the settings as
specified in setup (or the defaults).

If the buffer was already attached (i.e. being highlighted), the settings will
be reloaded with the ones from setup. This is useful for reloading settings
for just one buffer.


|:ColorizerDetachFromBuffer|                         *:ColorizerDetachFromBuffer*

Stop highlighting the current buffer (detach).

|:ColorizerReloadAllBuffers|                         *:ColorizerReloadAllBuffers*

Reload all buffers that are being highlighted with new settings from the setup
settings (or the defaults). Shortcut for ColorizerAttachToBuffer on every
buffer.

PARAMETERS:
	`filetypes`	 (optional) filetypes to enable. see examples below
	`default_options`  (optional) |colorizer-options|

  colorizer.setup([filetypes=nil], [default_options={}])

  " In your VIMRC
  lua require'colorizer'.setup()

  -- From lua
  -- Attaches to every FileType mode
  require 'colorizer'.setup()
  
  -- Attach to certain Filetypes, add special configuration for `html`
  -- Use `background` for everything else.
  require 'colorizer'.setup {
    'css';
    'javascript';
    html = {
  	  mode = 'foreground';
    }
  }
  
  -- Use the `default_options` as the second parameter, which uses
  -- `foreground` for every mode. This is the inverse of the previous
  -- setup configuration.
  require 'colorizer'.setup({
    'css';
    'javascript';
    html = { mode = 'background' };
  }, { mode = 'foreground' })
