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. 45 46 (function(mod) { 47 if (typeof exports == "object" && typeof module == "object") // CommonJS 48 mod(require("../../lib/codemirror"));
