What is this Python project?
Fixit allows the creation of custom lint rules, just like flake8 or pylint. In addition, fixit allows developers to apply code transformations, similar to 2to3.
What's the difference between this Python project and similar ones?
flake8/pyflakes and pylint use the ast or astroid modules to analyze the source code. The resulting abstract syntax tree is missing information, such as whether a string was surrounded by single or double quotes, or the number of whitespaces between two tokens. Fixit is based on libCST, which uses a concrete syntax tree as its base representation and retains all formatting.
Therefore, Fixit is not just a framework for lint rules, but a framework for code transformations. This can be used to enforce coding conventions or to ascertain certain properties of the source code like HTTP request timeouts.
