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' Example of usage: plugin.rb main # frozen_string_literal: true # name: discourse-linkedin-auth # about: Provides the ability to use LinkedIn as a login option. # meta_topic_id: 46818 # version: 1.0 # authors: Matthew Wilkin # url: https://github.com/discourse/discourse-linkedin-auth gem "omniauth-linkedin-oauth2", "1.0.0" register_svg_icon "fab-linkedin" register_asset "stylesheets/common.scss" enabled_site_setting :linkedin_enabled require_relative "lib/linked_in_authenticator" auth_provider authenticator: ::LinkedInAuthenticator.new, icon: "fab-linkedin" This file has been truncated. show original

Thanks, gave it a go but get the following error message: /home/kiffin/.rvm/rubies/ruby-2.3.1/lib/ruby/2.3.0/rubygems/dependency.rb:319:in `to_specs': Could not find 'rubyzip' (~> 1.1.6) among 186 total gem(s) (Gem::LoadError)

Did you run bundle install after adding the gem?

Gems declared in a plugin are installed and loaded differently as per our implementation: lib/plugin/instance.rb main # Allow to eager load additional tables in Search. Useful to avoid N+1 performance problems. # Example usage: # register_search_topic_eager_load do |opts| # %i(example_table) # end # OR # register_search_topic_eager_load(%i(example_table)) def register_search_topic_eager_load(tables = nil, &block) Search.custom_topic_eager_load(tables, enabled: method(:enabled?), &block) end # Request a new size for topic thumbnails # Will respect plugin enabled setting is enabled # Size should be an array with two elements [max_width, max_height] def register_topic_thumbnail_size(size) if !(size.kind_of?(Array) && size.length == 2) raise ArgumentError.new("Topic thumbnail dimension is not valid") end DiscoursePluginRegistry.register_topic_thumbnail_size(size, self) This file has been truncated. show original 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.

[image] kgish: namely docx in order to generate word docs. 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? [image]

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: From username 1365 2016-07-18T02:20:41.074Z Name: Jay User (username) Subject: Week 7 Discussion Date: 2016-07-28T02:20:41.074Z Post: 10 Reply-to: 9 Num-Replies: 0 Read-time: 30 Times-read: 21 Post-URL: https://literatecomputing.com/t/79/10 followed by either the HTML or the raw Markdown text.

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

I’m very interested in seeing your code!

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