Some additional patterns you might be interested in

Here are some patterns I've created after having this installed for only a few hours, it's been awesome!

To jump to Rubygems from a Gemfile (or it's alternative name, gems.rb):

{                                           
  pattern = "gem ['\"]([^%s]*)['\"]",       
  prefix = "https://rubygems.org/gems/",    
  suffix = "",                              
  file_patterns = { "Gemfile", "gems.rb" }, 
  excluded_file_patterns = nil,             
},                                          

Or to load the URL for a base image in Dockerhub:

-- Dockerfile images: unprefix, unnamespaced (the library images, like `ruby:3.2`) 
-- results in: https://hub.docker.com/_/ruby/                                      
{                                                                                  
  pattern = "^FROM ([^:.]+):",                                                     
  prefix = "https://hub.docker.com/_/",                                            
  suffix = "/",                                                                    
  file_patterns = { "Dockerfile%S*", "Containerfile%S*" },                         
  excluded_file_patterns = nil,                                                    
  extra_condition = function(matched_pattern)                                      
    return not matched_pattern:match("/")                                          
  end,                                                                             
},                                                                                 
-- Dockerfile images: unprefixed but namespaced (like crystallang/crystal)         
-- results in: https://hub.docker.com/r/crystallang/crystal                        
{                                                                                  
  pattern = "FROM ([^:.]+):",                                                      
  prefix = "https://hub.docker.com/r/",                                            
  suffix = "/",                                                                    
  file_patterns = { "Dockerfile%S*", "Containerfile%S*" },                         
  excluded_file_patterns = nil,                                                    
  extra_condition = function(matched_pattern)                                      
    return matched_pattern:match("/")                                              
  end,                                                                             
},

Thanks for this, I will add it as the default setting for plugins.
