Even though its web-based (therefor in browser) I tried to make it as much like a desktop app as possible (drop down menus, floating windows that are draggable, no page loads except for login/logout).

A fun as it must have been to re-implement a windowing system in dhtml, breaking the browser metaphor is a cardinal sin of ui design.

If you do continue down this route, ensure that the back button works, and you can open any link in a new tab.

I'm writing a logo interpreter in java script:

I've added variables, if, ifelse, infix operators (numerical and boolean), and it even interprets tail recursive functions properly.

It is still very rough, and the turtle draws it all at once, but I'm still working on a number of improvements.

Here are some fractals:

code:

repeat :arms [lt 360/:arms
pd fw :length
tree :arms 2 * :length / :arms :count - 1
pu bw :length]

ifelse :count = 1 [fw :length] [
make "count :count -1 
line :count :length
lt 60 line :count :length
rt 120 line :count :length

I've written a tiny functional (logical) language interpreter:

code:

$ cat append 
append [] list :- list 
append h,t list :- h,{append t list}

say {append [1 2] [3 4]}

say { append [1+2 2+3] [3+4 4+5] }


$ ./eval.pl append 
[1, 2, 3, 4] 
[[add, 1, 2], [add, 2, 3], [add, 3, 4], [add, 4, 5]] 

$ cat in 
say {every  x in [1 2]}

$ ./eval.pl in
[1, 2]

It's a prolog dialect with functions instead of predicates and explicit backtracking. The syntax is more like tk than haskell.

It's about 200 lines in total. :toot:

This is Komposter, a small modular "virtual analog" synth and sequencer I've been working on. It's mainly geared towards generating music from really tiny executables like 4K and 64K demoscene intros but can just as well be used for generating analog-like sounds. The previous version was downright user-hostile, so I made this to enable actual musicians to compose tunes for our intros.

I wanted to gain a deeper understanding of the JVM so I built a language that runs on top of it. It doesn't do much right now (in fact I've aptly named the language "Stoopid"), but after less than a week I've got the compiler to a point that's worth mentioning. Here's the reference code for that screenshot:

This inspired me to do my own take on it. I don't quite have if statements done, yet (to do it right, I'd have to start implement a basic graph algorithm, and I don't feel like doing that right now), but "Hello, world!" works!

I'll hopefully carve out more time to work on it, but it is just a little beyond the prototype stage and the documentation makes it look like english is not my first language.

json doesn't handle outside the bmp well.

quote:

To escape an extended character that is not in the Basic Multilingual
Plane, the character is represented as a twelve-character sequence,
encoding the UTF-16 surrogate pair. So, for example, a string
containing only the G clef character (U+1D11E) may be represented as
"\uD834\uDD1E".

the rfc also says things like this

quote:

Encoding considerations: 8bit if UTF-8; binary if UTF-16 or UTF-32

JSON may be represented using UTF-8, UTF-16, or UTF-32. When JSON
is written in UTF-8, JSON is 8bit compatible. When JSON is
written in UTF-16 or UTF-32, the binary content-transfer-encoding
must be used.

It isn't as pretty as everyone else's, but today I learned ruby and ported my rpc-esque library to it

Ruby code:

require "glyph"
s = Glyph.open('http://localhost:123456/')
q= s.make_queue('butt')
q.push('butts')
puts q.pop()

given a python server

Python code:

import glyph
import collections

queues = {}

m = glyph.Router()
@m.add()
def make_queue(name):
    if name not in queues:
        queues[name]=collections.deque()
    return Queue(name)    

@m.add()
class Queue(glyph.r):
    def __init__(self, name):
        self.name = name
    def push(self, msg):
        queues[self.name].appendleft(msg)

    def pop(self):
        if self.name in queues:
            return queues[self.name].popleft()

s = glyph.Server(m, port=12345)

hypermedia is just forms and links and stuff

when you make a call, you get a serialised object back - for the methods, it returns forms (like html), which include url and verb. when you call a method on the client side, it submits the form, and it in turn can return
more stuff.
