CodeMirror: APL mode
Simple mode that tries to handle APL as well as it can.
It attempts to label functions/operators based upon
monadic/dyadic usage (but this is far from fully fleshed out).
This means there are meaningful classnames so hover states can
have popups etc.
Simple mode that tries to handle C-like languages as well as it
can. Takes two configuration parameters: keywords, an
object whose property names are the keywords in the language,
and useCPP, which determines whether C preprocessor
directives are recognized.
Mode for HTML with embedded Django template markup.

CodeMirror: Dockerfile mode
Handles AT&T assembler syntax (more specifically this handles
the GNU Assembler (gas) syntax.)
It takes a single optional configuration parameter:
architecture, which can be one of "ARM",
"ARMv6" or "x86".
Including the parameter adds syntax for the registers and special
directives for the supplied architecture.
Mode for html embedded scripts like JSP and ASP.NET. Depends on multiplex and HtmlMixed which in turn depends on
JavaScript, CSS and XML. Other dependencies include those of the scripting language chosen.
The HTML mixed mode depends on the XML, JavaScript, and CSS modes.
It takes an optional mode configuration
option, scriptTypes, which can be used to add custom
behavior for specific <script type="..."> tags. If
given, it should hold an array of {matches, mode}
objects, where matches is a string or regexp that
matches the script type, and mode is
either null, for script types that should stay in
HTML mode, or a mode
spec corresponding to the mode that should be used for the
script.

JavaScript mode supports several configuration options:
json which will set the mode to expect JSON
data rather than a JavaScript program.
jsonld which will set the mode to expect
JSON-LD linked data rather
than a JavaScript program (demo).
typescript which will activate additional
syntax highlighting and some other things for TypeScript code
(demo).
statementIndent which (given a number) will
determine the amount of indentation to use for statements
continued on a new line.
wordCharacters, a regexp that indicates which
characters should be considered part of an identifier.
Defaults to /[\w$]/, which does not handle
non-ASCII identifiers. Can be set to something more elaborate
to improve Unicode support.
Loosely based on Franciszek
Wawrzak's CodeMirror
1 mode. One configuration parameter is
supported, specials, to which you can provide an
array of strings to have those identifiers highlighted with
the lua-special style.

version - 2/3 - The version of Python to recognize. Default is 2.
singleLineStringErrors - true/false - If you have a single-line string that is not terminated at the end of the line, this will show subsequent lines as errors if true, otherwise it will consider the newline as the end of the string. Default is false.
hangingIndent - int - If you want to write long arguments to a function starting on a new line, how much that line should be indented. Defaults to one normal indentation unit.
Advanced Configuration Options:
Usefull for superset of python syntax like Enthought enaml, IPython magics and questionmark help

The python mode will be used for highlighting blocks
containing Python/IPython terminal sessions: blocks starting with
>>> (for Python) or In [num]: (for
IPython).
Further, the stex mode will be used for highlighting
blocks containing LaTex code.

CodeMirror: Ruby mode
The XML mode supports these configuration parameters:
htmlMode (boolean)
This switches the mode to parse HTML instead of XML. This
means attributes do not have to be quoted, and some elements
(such as br) do not require a closing tag.
matchClosing (boolean)
Controls whether the mode checks that close tags match the
corresponding opening tag, and highlights mismatches as errors.
Defaults to true.
alignCDATA (boolean)
Setting this to true will force the opening tag of CDATA
blocks to not be indented.
Defines a mode that parses
a YAML frontmatter
at the start of a file, switching to a base mode at the end of that.
Takes a mode configuration option base to configure the
base mode, which defaults to "gfm".

CodeMirror: Z80 assembly mode
This is a list of every mode in the distribution. Each mode lives
in a subdirectory of the mode/ directory, and typically
defines a single JavaScript file that implements the mode. Loading
such file will make the language available to CodeMirror, through
the mode
option.
