Ruby Formatter
Format and beautify Ruby code with RuboCop-style 2-space indentation. Handles do/end and {} blocks, method definitions, and class structure.
Ruby Style Guide & RuboCop
Ruby uses 2-space indentation (unlike most other languages that use 4) as defined in the community Ruby Style Guide and enforced by RuboCop, the most widely used Ruby static analysis tool. Ruby has two block syntaxes: do/end for multi-line blocks and {} for single-line blocks. The Style Guide recommends do/end for blocks that span multiple lines.
