atom-ternjs package

Javascript code intelligence for atom with Tern. Uses suggestion provider by autocomplete-plus.

Installation

In your project root create a file named .tern-project

With default config via menu (Packages -> Atom Ternjs -> Create default .tern-project) or by adding it manually. See docs @ http://ternjs.net/doc/manual.html#configuration.
Check path in loadEagerly
Restart the server via Packages -> Atom Ternjs -> Restart server

Example .tern-project file (customize to your own needs):

{
  "libs": [
    "ecma5",
    "ecma6",
    "jquery"
  ],
  "loadEagerly": [
    "absolute/or/relative/path/to/your/js/**/*.js"
  ],
  "dontLoad": [
    "absolute/or/relative/path/to/your/js/**/*.js"
  ],
  "plugins": {
    "complete_strings": {},
    "node": {},
    "angular": {},
    "requirejs": {},
    "doc_comment": {
      "fullDocs": true
    }
  }
}

libs

browser: completion for vanilla js (optional)
ecma5: es5 (optional)
ecma6: es6 (optional)
jquery: completion for jQuery (optional)

options

loadEagerly: provide the path to your projects js. Absolute path is recommended, but not necessary. (For relative path do not use './' as a prefix. This sometimes leads to an unexpected behaviour)
dontLoad: can be used to prevent Tern from loading certain files. It also takes an array of file names or glob patterns.

plugins

complete_strings: When enabled, this plugin will gather (short) strings in your code, and completing when inside a string will try to complete to previously seen strings. Takes a single option, maxLength, which controls the maximum length of string values to gather, and defaults to 15. (optional)
doc_comment: tern will look for JSDoc-style type declarations. Returns the full comment text instead of the first sentence. (optional)
node: NodeJS (optional)
angular: AngularJS (optional)
requirejs: RequireJS (optional, understand RequireJS-style dependency management)
For a list of possible plugins goto http://ternjs.net/doc/manual.html#plugins

.tern-project created/modified

After the file was created or has been modified, restart the server via Packages -> Atom Ternjs -> Restart server

Platform Windows

Make sure node is installed and the PATH variable is set
