A tooling framework for analyzing and modifying large codebases automatically.
Proved on 2 million lines of code.
Supports Java 6/7/8 (Modification on Java 8 code is not fully tested).
Requirement: JDK 8
Build: gradle shadowJar
Run: java -jar build/libs/exia-2.0-all.jar [solver-name] [paths-being-scanned...]
For example:
java -jar build/libs/exia-2.0-all.jar UnusedImportDeletor /home/sorra/projects/
To learn how to write your own tool, see examples in the package com.iostate.exia.solvers about how to:
- Remove unused imports
- Detect the places you have forgotten to write
logger.isDebugEnabled() - Fix the places you have forgotten to write
logger.isDebugEnabled() - Fix the misuse of
logger.error(...)API - Fix the wrong logger name mismatching its enclosing class
There are two extension points: FileFilter & AstFunction.
Implement them and call FileWalker to run your own operations.
(The default FileFilter is com.iostate.exia.api.JavaSourceFileFilter)
The package com.iostate.exia.ast provides convenient AST utilities.
- Implemented in Java 8.
- Upgraded JDT library to 3.12.3 in maven central.
- Changed the build tool to Gradle.
- Single-threaded (fast enough, why not make it easy to debug?)
- Better API.
- More useful examples.
- Will add intelligence.
