+// This module provides an alternative parser (`parse_dammit`) that
+// exposes that same interface as `parse`, but will try to parse
+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make
+// invasive changes and simplifications without creating a complicated

+// 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
+// * caseInsensitive: boolean to send case insensitive querys to tern
+//
+//
+// 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.
