Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. Rake has the following features: * Rakefiles (rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?) * Users can specify tasks with prerequisites. * Rake supports rule patterns to synthesize implicit tasks. * Flexible FileLists that act like arrays but know about manipulating file names and paths. * Supports parallel execution of tasks.

Questions about RubyGems

Can I run it with my own inputs?

Yes. Change the inputs in Studio and press Run, or send new inputs from your code, or ask a connected AI assistant.

Can I call this RubyGems tool as an API?

Yes. Send a POST request to /v1/query with your Fous API key and the inputs, and get JSON back.

How much does it cost?

Each completed run costs 1 credit. Failed runs without a completed receipt are free; completed work can remain charged if delivery is interrupted. With pay as you go, a credit costs 1¢. Monthly plans cost less per credit.

Do I need a RubyGems account?

No. You only need a Fous account.

How current is the data?

Fous gets the data from rubygems.org when you run it. Some results are reused for up to 24 hours, and results that use your account or key are never reused. It was last verified on Sep 29, 2026.
