I recently started using YARD to view my documented source code in an HTML format. I really like the syntax and navigation that the web interface provides, and I feel that having this nicely formatted display of documentation really pushes me to think more about commenting my code while developing. Starting the YARD server locally is as easy as installing the gem, generating the docs and starting the server.
But I found that it’s a bit of a pain in the ass to actually view documentation while it’s undergoing changes. While you can run the server in “reload” mode, this requires your entire documentation to be re-generated on every request, and I feel that it’s wildly inefficient and slow. To remedy this problem I released a gem that integrates with guard to bring you a speedy and up-to-date YARD Documentation Server.
There are two major benefits to the guard-yard gem. The first is that it provides a consolidation of all file-monitoring processes to guard. This means you only need to run guard to keep your documentation server up-to-date and running. There is no need to configure the YARD server or re-processes your documentation on every request. The second benefit is that the docs are updated quickly. The guard-yard gem only modifies the documentation for files that have actually changed. This means that viewing your changes happens sooner!
Staring the YARD server via guard-yard is very easy:
- Install guard, guard-yard, and yard gems.
- Update your Guardfile using
guard init yard.
- Start the Guard server using
