(synopsis "Concrete Syntax Tree (CST) parser and serializer library for Python")
"LibCST parses Python source code as a CST tree that keeps all
formatting details (comments, whitespaces, parentheses, etc). It's useful
for building automated refactoring (codemod) applications and linters.
LibCST creates a compromise between an Abstract Syntax Tree (AST) and
a traditional Concrete Syntax Tree (CST). By carefully reorganizing and
naming node types and fields, LibCST creates a lossless CST that looks and
feels like an AST.")
