I’ve recently becoming interested in porting legacy PHP sites to JSPs. It seemed to me that one of the hardest parts of this problem was parsing the PHP code. Once a parse tree was created, the next step would be to emit equivalent JSP code.
I went looking for an ANTL4 grammar for PHP, but could only find an ANTLR3 grammar, so I went to work updating the ANTLR3 grammar to ANTLR4 and writing a very simple validation suite. The github project is here, and the resulting grammar is here.
I’ve always had a fascination with compilers. As a Java geek, I’m also quite interested in the JVM. In order to learn a little more about both, and as a way to contribute to the open source world, I decided to implement a compiler for BASIC. So, jvmBasic consumes BASIC code and emits .class…
I’ve recently become very interested in blockchain, and that, naturally led me to Ethereum and Bitcoin. From there, I got a little interested in online trading, but since I prefer not to have to think about trading, I started thinking about a trading bot. Part of the work I needed to do was write a…

Back in the day, Paradox was a pretty amazing database. I recently had a reason to read some Paradox files for a friend, who had a client with a Paradox database. They needed their data out of the database to insert into something more modern. Googling for the file format of a Paradox DB didn’t…
I’ve tried a couple different mp3 taggers to tag my mp3 library, however, most seem to have trouble with large mp3 libraries. So, after doing some reading about AcoustID and MusicBrainz I decided to quickly code up my own tagger, MusicBrainzTagger. MusicBrainzTagger is a command-line application which recurses a directory of mp3 files and tags…
