    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Smaller uncompressor, only takes about a second to boot up!

Here's the compressor code... $="for(c.width|=i=9;i--;)x.fillRect(400+i*99+S(t)*300,400,50,200)";n=[...new Set([...(';'+$)])].join(o='');for(v=i=0;(q=$[i])||i%4;++i)v+=q?n.indexOf(q)<<i%2*5:0,i%2?(o+=String.fromCharCode(((i%4==3?55:54)<<10)+v),v=0):0;throw 't?eval(O+="'+n+'"["'+o+'".charCodeAt(I/2)>>I++%2*5&31]):I=O=""'

From my testing it can do up compress up to 224 characters of code if all of the unique 32 characters are used!

u/tomxor

Swapping the ternary statement for }{I=O="" at the end saves one more char.
u/tomxor

But this will only work on a new dweet
u/tomxor

Really need a larger charset though :/ I think 64 should be enough for most, which bumps it up to 6 bits, but that requires a lot more code to extract, might still be better than 184 though?
u/tomxor

Nah, before even considering extra decompression code, 6 bits with 32 dictionary barely provides 192 chars, as soon as you start actually filling the dictionary with more you quickly go under 140 encoded chars. I think you hit the best balance for this method.
u/KilledByAPixel

i think 5 bits is the sweet spot, it is definitely tough writing code that only uses 32 chars but maybe we can see some programs that would not otherwise be possible
u/DataMeta

#hiddengem
u/ximavus

maybe we can use a hybrid 5-6 bits? like any char index that is even is 5 bits and every odd one is 6. Don't know if this would fit and I have no idea for compressors

4-1 compressed #default

u/tomxor

Reduced character set encoding :P I was literally thinking to do the same thing, also this is how some SMS txt compression standards work apparently.

New 4-1 compressor proof of concept! In this example the compressed code is 208 chars.

u/KilledByAPixel

#COMPRESSOR replace $ with your code... $="for(c.width|=i=9;i--;)x.fillRect(400+i*99+S(t)*300,400,50,200)";n=[...new Set([...(';'+$)])].join(o='');for(v=i=0;(q=$[i])||i%4;++i)v+=q?n.indexOf(q)<<i%2*5:0,i%2?(o+=String.fromCharCode(((i%4==3?55:54)<<10)+v),v=0):0;throw 'for(I=O="";Q="'+o+'".charCodeAt(I/2);O+="'+n+'"[Q>>I++%2*5&31]);eval(O)'
u/tomxor

This is way better than my crazy delta compressor, but it's still surprisingly difficult to stick to a 32 char set.

Saved 9 more... although it decodes at 1 bit per second !!

u/tomxor

Decoder now = 90 chars, leaving 50*20/7 = 142 chars of content yay! +2 chars
u/tomxor

To break even with 184 chars, 184*7/20 = 67 20bit chars, leaving 73 for decoder, not sure this is possible :/
u/tomxor

... I guess 1bit/s is just not good enough for the internet of the 21st century XD
