Instructions

Use ri [options] <whatever> to look up information about Ruby classes, modules, and methods.

  • Combine with head to fast check documentation before displaying full content.
  • Combine with wc to count relevant items when searching for multiple entries.
  • Combine with grep to filter results based on keywords.

Consider to add quote to queries with special characters to avoid shell interpretation issues. e.g. ri 'String#blank?'
