| 4 |
// Glue code between CodeMirror and Tern. |
| 5 |
// |
| 6 |
// Create a CodeMirror.TernServer to wrap an actual Tern server, |
| 7 |
// register open documents (CodeMirror.Doc instances) with it, and |
| 8 |
// call its methods to activate the assisting functions that Tern |
| 9 |
// provides. |
| 10 |
// |
| 11 |
// Options supported (all optional): |
| 12 |
// * defs: An array of JSON definition data structures. |
| 13 |
// * plugins: An object mapping plugin names to configuration |
| 14 |
// options. |
| 15 |
// * getFile: A function(name, c) that can be used to access files in |
| 16 |
// the project that haven't been loaded yet. Simply do c(null) to |
| 17 |
// indicate that a file is not available. |
| 18 |
// * fileFilter: A function(value, docName, doc) that will be applied |
| 19 |
// to documents before passing them on to Tern. |
| 20 |
// * switchToDoc: A function(name, doc) that should, when providing a |
| 21 |
// multi-file view, switch the view or focus to the named file. |
| 22 |
// * showError: A function(editor, message) that can be used to |
| 23 |
// override the way errors are displayed. |
| 24 |
// * completionTip: Customize the content in tooltips for completions. |
| 25 |
// Is passed a single argument—the completion's data as returned by |
| 26 |
// Tern—and may return a string, DOM node, or null to indicate that |
| 27 |
// no tip should be shown. By default the docstring is shown. |
| 28 |
// * typeTip: Like completionTip, but for the tooltips shown for type |
| 29 |
// queries. |
| 30 |
// * responseFilter: A function(doc, query, request, error, data) that |
| 31 |
// will be applied to the Tern responses before treating them |
| 32 |
// |
| 33 |
// |
| 34 |
// It is possible to run the Tern server in a web worker by specifying |
| 35 |
// these additional options: |
| 36 |
// * useWorker: Set to true to enable web worker mode. You'll probably |
| 37 |
// want to feature detect the actual value you use here, for example |
| 38 |
// !!window.Worker. |
| 39 |
// * workerScript: The main script of the worker. Point this to |
| 40 |
// wherever you are hosting worker.js from this directory. |
| 41 |
// * workerDeps: An array of paths pointing (relative to workerScript) |
| 42 |
// to the Acorn and Tern libraries and any Tern plugins you want to |
| 43 |
// load. Or, if you minified those into a single script and included |
| 44 |
// them in the workerScript, simply leave this undefined. |
