-- `context-coloring-default-delay` (default: `0.25`; supported modes: `js-mode`,
- `js3-mode`): Default (sometimes overridden) delay between a buffer update and
- colorization.
-- `context-coloring-js-block-scopes` (default: `nil`; supported modes:
- `js2-mode`): If non-nil, also color block scopes in the scope hierarchy in
- JavaScript.
-
-### Color Schemes
-
-Color schemes for custom themes are automatically applied when those themes are
-active. Built-in theme support is available for: `ample`, `anti-zenburn`,
-`grandshell`, `leuven`, `monokai`, `solarized`, `spacegray`, `tango` and
-`zenburn`.
-
-You can define your own theme colors too:
-
-```lisp
-(context-coloring-define-theme
- 'zenburn
- :colors '("#dcdccc"
- "#93e0e3"
- "#bfebbf"
- "#f0dfaf"
- "#dfaf8f"
- "#cc9393"
- "#dc8cc3"
- "#94bff3"
- "#9fc59f"
- "#d0bf8f"
- "#dca3a3"))
-```
-
-See `C-h f context-coloring-define-theme` for more info on theme parameters.
-
-## Extending
-
-To add support for a new language, write a "scopifier" for it, and define a new
-coloring dispatch strategy with `context-coloring-define-dispatch`. Then the
-plugin should handle the rest. (See `C-h f context-coloring-define-dispatch`
-for more info on dispatch strategies.)
-
-A "scopifier" is a CLI program that reads a buffer's contents from stdin and
-writes a JSON array of numbers to stdout. Every three numbers in the array
-represent a range of color. For instance, if I fed the following string of
-JavaScript code to a scopifier
-
-```js
-var a = function () {};
-```
-
-then the scopifier would produce the following array
-
-```js
-[1,24,0,9,23,1]
-```
-
-where, for every three numbers, the first number is a 1-indexed start [point][],
-the second number is an exclusive end point, and the third number is a scope
-level. The result of applying level 0 coloring to the range [1, 24) and
-then applying level 1 coloring to the range [9, 23) would result in the
-following coloring:
-
-<p align="center">
- <img alt="Screenshot of ranges [1, 24) and [9, 23)." src="scopifier.png" title="Screenshot">
-</p>
-
-If there is an abstract syntax tree generator for your language, you can walk
-the syntax tree, find variables and scopes, and build their positions and levels
-into an array like the one above.
-
-For example, a Ruby scopifier might be defined and implemented like this:
-
-```lisp
-(context-coloring-define-dispatch
- 'ruby
- :modes '(ruby-mode)
- :executable "ruby"
- :command "/home/username/scopifier")
-```
-
-```ruby
-#!/usr/bin/env ruby
-def scopifier(code)
- # Parse code.
- # Return an array.
-end
-print scopifier ARGF.read
-```
-
-When a `--version` argument is passed, a scopifier should print its version
-number and exit. This allows context-coloring to determine if an update is
-required.
-
-Alternatively, you could implement a "colorizer" in Emacs Lisp. A colorizer
-also handles the job of calling `context-coloring-colorize-region` to apply
-colors to a buffer. A colorizer may have better performance than a scopifier
-when parsing and coloring can be performed in the same pass.
