Plugin using own gem

Dev

I am developing a plugin that needs to use an external gem, namely docx in order to generate word docs.

Is there someway to do this or do I have to append it to the Gemfile?

There is a way to do it. You put the following in your plugin.rb file

gem 'omniauth-linkedin-oauth2', '0.1.5'

Thanks, gave it a go but get the following error message:

Did you run bundle install after adding the gem?

Yeah on your dev machine you will have to do bundle install. Docker does that for you, I believe.

Gems declared in a plugin are installed and loaded differently as per our implementation:

In order to get it to work, you’ll have to specify all the gem’s dependencies which are not already included in the Gemfile.

What’s your plugin going to do? I’ve got a client who would love to be able to export a topic as a Word document.

I’ve created a plugin that does just that, click on the word-icon, interested?

I"m sure she will be. I just wrote a Ruby program that takes either a topic or category URL on the command line and downloads a topic (or all of them in the category) as a sort-of MBOX file with headers like these:

I guess that’s one way of doing it. My method however does something similar and delivers the generated doc directly to the user.
