Fedora Update Notification
FEDORA-2026-17c484fafa
2026-07-18 00:26:14.272987+00:00
--------------------------------------------------------------------------------

Name        : python-libcst
Product     : Fedora 44
Version     : 1.8.6
Release     : 4.fc44
URL         : https://github.com/Instagram/LibCST
Summary     : A concrete syntax tree with AST-like properties for Python 3
Description :
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, it creates a lossless CST that looks and feels like an
AST.
