Articles about extracting data from code, analyze it and programmatically transform it. In other words we talk about static analysis, automated refactoring, and code generation.
We are getting closer to the first Release Candidate for JavaParser 3.0. One of the last features we added was support for observing changes to all nodes of the Abstract Syntax Tree. While I wrote the code for this feature I received precious feedback from Danny van Bruggen (a.k.a. Matozoid) and Cruz Maximilien. So I […]
Erik Dietrich is a well known Software Architect with a long experience in consulting. His blog (DaedTech) is a source of thoughtful insights on software development. In particular I was very interested by his usage of static analysis and code metrics in his consulting work. I am myself a relatively young consultant and I thought […]
Beyond the source code Last week we have seen how to use Roslyn to rewrite source code to your liking. That’s all well and good, but it’s not the only thing you can do when you have a compiler open and ready to do your bidding. Another possibility is to leverage the knowledge that the […]
Why I created the java-symbol-solver? A few years ago I started using JavaParser and then I started contributing. After a while I realized that many operations we want to do on Java code cannot be done just by using the Abstract Syntax Tree produced by a parser, we need also to resolve types, symbols and […]
Recently I have been playing with some ideas about applying static analysis to Python and building a Python editor in Jetbrains MPS. To do any of this I would need to first build a model of Python code. Recently we have seen how to parse Python code, however we still need to consider all the […]
One of the things I like the most is to parse code and to perform automatic operations on it. For this reason I started contributing to JavaParser and created a couple of related projects: java-symbol-solver and effectivejava. As a contributor of JavaParser I read over and over some very similar questions about extracting information from Java source code. For this […]
I am very interested in tools which support the software development process, making automatic the boring bits. One system which permits to go in that direction is Walkmod: a smart tool which can refactor Java projects and enforce code conventions. It is a quite powerful tool and it should ges more and more attention. TL; DR: Tools […]
Last week we have seen how to build models of Java code from source and JAR files. Now we want to be able to solve symbols: in practice we want to link the symbol references in our source code to symbol declarations either in Java source files or jar files. This process is called symbol […]
Recently I spent some time working on effectivejava, which is on its way to reach 300 stars on GitHub (feel free to help reaching the target :D). Effectivejava is a tool to run queries on your Java code. It is based on another project I contribute to, javaparser. Javaparser takes as input Java source code […]
When I was working at TripAdvisor we had this internal book club. We started by reading Effective Java, this very famous book from Joshua Bloch. It is interesting and all but I think this book was so successful that most of his advices are now part of the Java culture: most of Java developers know them and sort […]
