+// Glue code between CodeMirror and Tern.
+//
+// Create a CodeMirror.TernServer to wrap an actual Tern server,
+// register open documents (CodeMirror.Doc instances) with it, and
+// call its methods to activate the assisting functions that Tern
+// provides.
+//
+// Options supported (all optional):
+// * defs: An array of JSON definition data structures.
+// * plugins: An object mapping plugin names to configuration
+// options.
+// * getFile: A function(name, c) that can be used to access files in
+// the project that haven't been loaded yet. Simply do c(null) to
+// indicate that a file is not available.
+// * fileFilter: A function(value, docName, doc) that will be applied
+// to documents before passing them on to Tern.
+// * 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
+
+
+
+
+
+
+
+
+
+
+
+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.
+
+ MIME types defined: text/apl

, which determines whether C preprocessor
