rubygem-syntax_tree

Parser based on ripper

Syntax Tree is a suite of tools built on top of the internal CRuby parser. It provides the ability to generate a syntax tree from source, as well as the tools necessary to inspect and manipulate that syntax tree. It can be used to build formatters, linters, language servers, and more. It is built with only standard library dependencies. It additionally ships with a plugin system so that you can build your own syntax trees from other languages and incorporate these tools.
