7
+ //
8
+ // Options supported (all optional):
9
+ // * defs: An array of JSON definition data structures.
10
+ // * plugins: An object mapping plugin names to configuration
11
+ // options.
12
+ // * getFile: A function(name, c) that can be used to access files in
13
+ // the project that haven't been loaded yet. Simply do c(null) to
14
+ // indicate that a file is not available.
15
+ // * fileFilter: A function(value, docName, doc) that will be applied
16
+ // to documents before passing them on to Tern.
17
+ // * switchToDoc: A function(name) that should, when providing a
18
+ // multi-file view, switch the view or focus to the named file.
19
+ // * showError: A function(editor, message) that can be used to
20
+ // override the way errors are displayed.
21
+ // * completionTip: Customize the content in tooltips for completions.
22
+ // Is passed a single argument—the completion's data as returned by
23
+ // Tern—and may return a string, DOM node, or null to indicate that
24
+ // no tip should be shown. By default the docstring is shown.
25
+ // * typeTip: Like completionTip, but for the tooltips shown for type
26
+ // queries.
27
+ // * responseFilter: A function(doc, query, request, error, data) that
28
+ // will be applied to the Tern responses before treating them
29
+ //
30
+ //
31
+ // It is possible to run the Tern server in a web worker by specifying

+ // !!window.Worker.
36
+ // * workerScript: The main script of the worker. Point this to
37
+ // wherever you are hosting worker.js from this directory.
38
+ // * workerDeps: An array of paths pointing (relative to workerScript)
39
+ // to the Acorn and Tern libraries and any Tern plugins you want to
40
+ // load. Or, if you minified those into a single script and included
41
+ // them in the workerScript, simply leave this undefined.
