How to install?

[emielvangoor]

Hi,

How do I install tern.jsduck, I'm new to ternjs and I don't know where to start. I created a .tern-project file in my root directory. What do I need to do now? I installed JSDuck and I'm using ExtJS 6...

Thanks in advance..

tern-jsduck is used to generate tern plugin for CKEditor, ExtJS. If you wish do that:

• copy https://github.com/angelozerr/tern.jsduck/blob/master/plugin/ckeditor_4.4.7.js in your tern/plugin file sytem folder.
• declare in your .tern-project

{
  "ecmaVersion": 6,
  "libs": ["browser"],
  "plugins": {
    "ckeditor_4.4.7": {}
  }
}

@angelozerr Thanks for your reply! I downloaded the extjs_5.0.0.js and placed it in the tern/plugin folder and created the .tern-project as you suggested

Now tern throws the following error:

/usr/local/lib/node_modules/tern/lib/def.js:243
    if (/^fn\(/.test(spec)) for (var i = 0; i < type.args.length; ++i) (function

Which version of ternjs are you using? With tern 0.17.0 and Eclipse IDE (tern.java), it works great.

I suggets you that you share your project.

@emielvangoor That's a TernJS issue I also encountered with version 0.18.0. See this issue ternjs/tern#733 (PR #734 has been proposed).

@emielvangoor please retry it, I have fixed the problem by waiting the fix of ternjs.
