We love open source at Artsy. We use a ton of it. We've also contributed to numerous projects and created many of our own projects since early 2011. We maintain a philosophy of keeping our work Open by Default.

A library for generating a list of licensed software from Gemspec. The overwhelming majority of 3rd party licenses require the application that uses them to reproduce the license verbatim in an artifact that is installed with the application itself. Are you currently copying individual license.txt files 'by hand' or are you including license text in your documentation with copy/paste? This project aims at improving this situation.

The rspec-rerun gem is a drop-in solution to retry (rerun) failed RSpec examples. It may be useful, for example, with finicky Capybara tests. The strategy to rerun failed specs is to output a file called `rspec.failures` that contains a list of failed examples and to feed that file back to RSpec via `-e`.

A Ruby full-text search implementation for the Mongoid ODM. MongoDB currently has no native full-text search capabilities, so this gem is a good fit for cases where you want something a little less than a full-blown indexing service like Solr. The mongoid_fulltext gem lets you do a fuzzy string search across relatively short strings, which makes it good for populating autocomplete boxes based on the display names of your Rails models but not appropriate for, say, indexing hundreds of thousands of HTML documents.

Typical as_json definitions may involve lots of database point queries and method calls. When returning collections of objects, a single call may yield hundreds of database queries that can take seconds. This library mitigates the problem by implementing a module called CachedJson. CachedJson enables returning multiple JSON formats from a single class and provides some rules for returning embedded or referenced data. It then uses a scheme where fragments of JSON are cached for a particular (class, id) pair containing only the data that doesn't involve references/embedded documents. To get the full JSON for an instance, CachedJson will combine fragments of JSON from the instance with fragments representing the JSON for its references. In the best case, when all of these fragments are cached, this falls through to a few cache lookups followed by a couple Ruby hash merges to create the JSON. Using Mongoid::CachedJson we were able to cut our JSON API average response time by about a factor of 10.
