It has not been a good week. I set out on Tuesday to actually add real objects to PICKLE, with a hashmap of properties and multiple inheritance and everything. Suffice to say, that wasn’t easy. Between null pointer dereferencing, sloppy APIs, and an incomplete algorithm, it took several hours …

I’ve been trying to write some of the code to implement PICKLE’s parser and evaluator – it’s not going well. The hard part is that everything in PICKLE is done using continuation-passing style. Everywhere the evaluator has a chance of calling user code (that may capture a continuation …

I did a lot. In the two months since I last shared something I’ve worked on no less than four different projects, all while trying to slip them in between an avalance of schoolwork and college applications. Oh, and I also spent a week sick with COVID-19. (It’s …

After I made the last post – where I decided that PICKLE would be done in continuation-passing style – I revisted one extremely simple toy programming language done in continuation-passing style I found online (here). I figured it would be a good example of how I could implement PICKLE. The only problem …

Unfortunately that time of year has crept up… school has started again. And not just any kind of school: I find myself in 12^th grade, balancing seven classes, two with AP tests at the end, three with huge final projects. I’m also trying to apply to college at …

I worked for a while last week on the PICKLE implementation in Python. As I no longer have to work on the garbage collector, after I wrote a little “glue code” I immediately dove into the core functionality of PICKLE: the pattern-matching engine. Once I get the algorithm down, I …

I did a lot of work on Tinobsy, the garbage collector for PICKLE. It’s pretty robust now, and passes all my tests – plus I translated it to C++ so I can take advantage of C++’s syntactic sugar for objects. All I think that I’ll be doing with …

Yet again I find myself writing a garbage collector.

I did a little work on PICKLE’s Javascript implementation, and perhaps Javascript is not the right choice. Because Javascript’s inheritance model is so similar to PICKLE’s, yet slightly different, implementing the inheritance (even with ES6 Proxys) is …

I’m starting to work on my Pickle programming language, this time in Javascript. After only a few days’ work, I’m surprised I got so much working. Currently I have both the tokenizer and the inheritance system working. The syntax of Pickle is pretty much in place now, and …

I’ve been working quite a lot on my second programming language attempt, PICKLE. Admittedly, programming it in C has been a real chore. I started following the Make-A-Lisp tutorial to try to give myself some plan for executing PICKLE. Mal, unfortunately, recommends dynamically typed languages; that unfortunately is a …
