atom-ternjs package

Javascript code intelligence for atom with tern.js. 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:

{
  "libs": [
    "browser",
    "jquery"
  ],
  "loadEagerly": [
    "absolute/or/relative/path/to/your/js/**/*.js"
  ],
  "plugins": {
    "complete_strings": {},
    "doc_comment": {
      "fullDocs": true
    }
  }
}

• Absolute path is recommended, but not necessary
• loadEagerly: recommended, but not necessary. If no files are provided via 'loadEagerly', tern will register all files opened in the current workspace
• 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)
• browser: completion for vanilla js (optional)
• jquery: completion for jQuery (optional)

.tern-project created/modified

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