C headers are annoying. I was getting fed up with uLisp and so I decided to run another Google search for “embeddable scripting language for Arduino”.
It turned up mruby-arduino – poorly documented, and a little too big for my needs.
It turned up eLua – which unfortunately is just a flashable …
Today I decided I would have a little fun with Lisp. I wanted to try and make a program that you can type in a function and get a graph of it.
I started off with a function that takes an $x$-value and a list of coefficients, and evaluates …
For a while I have been trying to work out some bugs in David Johnson-Davies’ uLisp interpreter for Arduinos. I ported some macro and quasiquote extensions for an older version of uLisp to the current version, and apparently I did not do something right – it crashes whenever I try to …
I have finally written code that actually compiled and ran on the little ESP32 board I bought, and I hate the blasted thing already.
For starters, the process is slow, annoying, and tedious:
Over the weekend I joined the conwaylife.com forums because I am interested in cellular automata. I find watching the mechanisms mesmerizing, and building them exciting.
I also have an interest in music, and so a year or two ago I tried to generate music from cellular automata. I used …
Last time I had just announced that Phoo was finished. Well, it’s still finished — except for the fact that the online console no longer works. I tried porting the shell code to Phoo, but that ended up breaking the shell!
It was pretty much a line-for-line translation, so I …
…Gosh, I just realized that I haven’t posted anything in weeks. I really don’t want to fall prey to the obsession of posting everything online. I hope I’m not.
Anyway, I just finished up the first draft of the documentation of Phoo. The generator script is Python …
I am currently working on an online console for Quackery that is using the Pyodide in-browser Python interpreter. The only bad thing is, Python’s input() function blocks until input is provided, which can’t be done in the browser because everything is asynchronous. The only way for it to …
In developing Phoo today I was unpleasantly presented with yet another reason why I prefer Python. It was when I was working on the new Importer API for loading external modules into Phoo that I accidentally did this:
class Importer { /* stub class */ }
class FetchImporter extends Importer {
constructor(basePath, fetchOptions = {}) {
/* no …After several days trying to debug the horribly bug-ridden local-echo package for xterm.js, I have had enough. It’s Ioannis’ responsibility to debug his package. I am switching over to another Javascript terminal ptogram I found, jquery.terminal by Jakub T. Jankiewicz. It has built-in readline support, and well …
It has come up often where I have a file on my parent’s Mac that I need to send to my computer. Any Apple user would probably just use Airdrop. But I use Linux!… So I created a little Python script that allows sending files between computers with the …
I have finally gotten to the point in Phoo’s development that I am ready to set up the web interface.
I chose xterm.js for the terminal interface because I intend for Phoo to be able to be run in Nodejs as well as in the browser, but I …
Several moths ago I stumbled upon Gordon Charlton’s Quackery language while paroosing Github for something. Usually I don’t pay much attention to obviously irrelevant search results, but this one seemed worth a look. I found Quackery to be a simple stack-based semi-compiled language that makes infrequent use of …
