How does codemodder compare to jscodeshift/JavaParser/Semgrep/libcst?

codemodder is a collection of language-specific frameworks for building codemods. Other tools are really good at searching code for patterns (like Semgrep or PMD), or mutating code (like jscodeshift or JavaParser.) The purpose of codemodder is to make it very easy orchestrate these tools together to quickly build powerful codemods. Many tools could be used in orchestration of a codemodder codemod.

How does codemodder compare to OpenRewrite?

At a high level, we are both codemod development tools (except they call them "recipes"). There are multiple differences in the technical approach between OpenRewrite and codemodder. While we appreciate their work on building a complete stack for codemod development, we're focused on orchestration of idiomatic community tools and integration with other tools.

How does codemodder relate to Pixeebot?

The team behind Pixeebot delivers code improvements using codemodder-based codemods and sponsors the development of codemodder.
