[Funding status: ](https://marijnhaverbeke.nl/fund/)
CodeMirror is a JavaScript component that provides a code editor in
the browser. When a mode is available for the language you are coding
in, it will color your code, and optionally help with indentation.
The project page is http://codemirror.net
The manual is at http://codemirror.net/doc/manual.html

/**
* Tag-closer extension for CodeMirror.
*
* This extension adds an "autoCloseTags" option that can be set to
* either true to get the default behavior, or an object to further
* configure its behavior.
*
* These are supported options:
*
* `whenClosing` (default true)
* Whether to autoclose when the '/' of a closing tag is typed.
* `whenOpening` (default true)
* Whether to autoclose the tag when the final '>' of an opening
* tag is typed.
* `dontCloseTags` (default is empty tags for HTML, none for XML)
* An array of tag names that should not be autoclosed.
* `indentTags` (default is block tags for HTML, none for XML)
* An array of tag names that should, when opened, cause a
* blank line to be added inside the tag, and the blank line and
* closing line to be indented.
*
* See demos/closetag.html for a usage example.

// indicate that a file is not available.
// * fileFilter: A function(value, docName, doc) that will be applied

// * switchToDoc: A function(name, doc) that should, when providing a
// multi-file view, switch the view or focus to the named file.
// * showError: A function(editor, message) that can be used to
// override the way errors are displayed.
// * completionTip: Customize the content in tooltips for completions.
// Is passed a single argument—the completion's data as returned by
// Tern—and may return a string, DOM node, or null to indicate that
// no tip should be shown. By default the docstring is shown.
// * typeTip: Like completionTip, but for the tooltips shown for type
// queries.
// * responseFilter: A function(doc, query, request, error, data) that
// will be applied to the Tern responses before treating them
//
//
// It is possible to run the Tern server in a web worker by specifying
// these additional options:
// * useWorker: Set to true to enable web worker mode. You'll probably
// want to feature detect the actual value you use here, for example
// !!window.Worker.
// * workerScript: The main script of the worker. Point this to
// wherever you are hosting worker.js from this directory.
// * workerDeps: An array of paths pointing (relative to workerScript)
// to the Acorn and Tern libraries and any Tern plugins you want to
// load. Or, if you minified those into a single script and included
// them in the workerScript, simply leave this undefined.

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.
