ANTLR is a popular parser generator or “compiler-compiler”, developed by prof. Terence Parr and several contributors. It’s been around since 1992, as an evolution of PCCTS. It’s gone through multiple major versions. The latest incarnation of ANTLR is version branch 4.x, the first release of which is from 2013. Here at Strumenta, we use ANTLR4 […]
There is a new weapon in the great war against JavaScript the struggle to allow developers to choose their favorite style of programming while improve performance and productivity. That weapon is WebAssembly, that will revolutionize client-side web development. WebAssembly, or wasm, is a low-level bytecode format for in-browser client-side scripting. If you are writing a […]
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 […]
In this post we are going to see how to develop a simple language. We will aim to get: a parser for the language an editor for IntelliJ. The editor should have syntax highlighting, validation and auto-completion We would also get for free an editor for Eclipse and web editor, but please contain your excitement, we […]
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 […]
A few weeks ago I wrote a tutorial on getting started with Spark (the Java web framework). A few readers appreciated it and it was linked by the Jetbrains blog, republished by DZone and republished by the new Spark tutorials blog. After that me and David Åse chatted a bit and we decided to work together on […]
Recently I have been writing a RESTful service using Spark, a web framework for Java (which is not related to Apache Spark). When we planned to write this I was ready to the unavoidable Javaesque avalanche of interfaces, boilerplate code and deep hierarchies. I was very surprised to find out that an alternative world exists also for the […]
I spent a couple of hours playing with Frege (Haskell on the JVM) and not much documentation tutorials seems available. I am trying to help writing this simple Hello World tutorial. The code is available on Github: https://github.com/ftomassetti/frege-tutorial/tree/01_HelloWorld Update: Frege has some very useful documentation at http://www.frege-lang.org/doc/… where … represents the package, or module, name.
