// CodeMirror, copyright (c) by Marijn Haverbeke and others

// 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.
