The SOFTWARE-EVOLUTION-LIBRARY enables the programmatic modification and evaluation of software.

A common interface abstracts over multiple types of software objects including source code abstract syntax trees (primarily using tree-sitter), compiled assembler code, and binary software objects. Software transformation, analysis, and evaluation techniques are implemented on top of this interface supporting automation of common software engineering tasks.
