This is a work in progress plugin for prettier that supports the Ruby programming language. Under the hood it uses Ruby's own ripper library which allows this package to maintain parity with the existing Ruby parser.
Install the dependencies by running yarn in the root of the repository. You can then pretty print a ruby source file by running yarn print [PATH].
Below are the options (from src/index.js) that prettier-ruby currently supports:
inlineConditionals- When it fits on one line, allow if and unless statements to use the modifier form.inlineLoops- When it fits on one line, allow while and until statements to use the modifier form.preferHashLabels- When possible, use the shortened hash key syntax, as opposed to hash rockets.preferSingleQuotes- When double quotes are not necessary for interpolation, prefer the use of single quotes for string literals.
Currently, prettier-ruby drops a lot of comments.
