Fxforce5: code rewriter for DI with Uber FX

Gregory Golberg stealth0 , , , , , , ,

I am working on a project (closed source, sorry) that has suffered from proliferation of parameters to constructors, and for this (and other) reasons looks like it would benefit from a DI approach, such as Uber FX.

The code base is pretty large at this point, and manually adapting it is slow, tedious and frustrating. But laziness, impatience and hubris says: why not use features like static analysis using DST and reflection to automate this process?

So here is an attempt at doing that: https://github.com/debedb/fxforce5.

P.S. For a related approach used to automatically generate Swagger docs, see Swagger as you Go.

Java-to-Python converter

“Anything that can be done, could be done ‘meta'” (© Charles Simonyi) is right up there with “Laziness, impatience and hubris” (© Larry Wall) as pithy description of my development philosophy. Also, unfortunately, there’s another one: “Once it’s clear how toproceed, why bother to proceed” (or something like that). So, with that in mind…

I wanted a Python client library for GData (thankfully, they released
one last week, so this is moot — good!), so I thought of automagically converting the Java library to Python. I tried Java2Python, but it’s based on ANTLR grammar for Java 1.4, and the library, of course, is in Java 5. As I was relearning ANTLR and writing all these actions by hand (the pain!), I took a break and found
Java 1.5 parser with AST generation and visitor suport by Julio Gesser (no relation,
I presume?) and Sreenivasa Viswanadha, based on JavaCC. Aha! Much easier… But then, of course, Google releases the Python version of the library I needed in the first place, so I don’t bother wrapping this project up… Here it is for whoever wants it: http://code.google.com/p/j2p/.
