Saved another 7 chars (I think) from the uncompressor!

u/tomxor

Oh neat, 8 i think, I thought of moving _ directly into it's reference, but combining it with the condition is way better.
u/tomxor

This has also past the threshold at which d/9207 stops reducing (even when moving _ back into a reference.)
u/KilledByAPixel

I think it might be possible if the data was packed tighter, maybe we can do better then 7 bits per char
u/tomxor

yeah i've been secretly thinking this but haven't come up with anything particularly amazing yet... you only actually need 6.75 bits if you ommit the lower 32 control chars including space and tab, but it's too messy to mix in the combinations from other chars, probably need to lose some useful chars too.
u/tomxor

I meant tab and newline not space, both of which are pretty useless for dweets.

New Dwitter Compressor - Proof of Concept

Show more comments…
u/KilledByAPixel

Code converted to 7 bit ascii and packed into a unicode string using every available byte.
u/KilledByAPixel

Compression is nearly 3:1 (each output character holds 20 bytes which is almost 3 7 bit characters)
u/KilledByAPixel

The problem is the uncompressed is still too large for this to be useful, can we golf it?
u/tomxor

Neat idea. @ 3:1 we need to remove 34 chars to break even with d/9207 i think overhead should be max 78 chars = 140 - 184/3
u/tomxor

Heh, I managed to add 8 O+=eval(`'\\${(V).toString(8)}'`)
u/tomxor

+!V could be omitted if the encoder simply padded the input with a space to make an even number.
u/tomxor

Also ?0: can be replaced with ||
u/tomxor

Ah, I don't mean input even, i mean output even... which I guess is easier to do with a condition that checks for the lower surrogate being zero and replaces with 0x20
u/tomxor

argh no i'm getting confused I was right first time, the condition is on i%7
u/tomxor

no that was a terrible idea, I can see why you chose !V, since you don't have to check length and even if you did the minimum number of extraneous bits is 1, which in the 7th position is 0x40 (@) which doesn't eval...
u/KilledByAPixel

tomxor, good ideas! keep em comming. ?0: to || saves 1 byte!

how the actual flip did you get 232 characters in there
u/KilledByAPixel

416 bytes, 140 characters ;)
u/tomxor

Or 140 unicode code-points (how the server evaluates length), 232 UTF16 chars (how JS in the browser evals length), and 198 effective bytes (134 chars provided by the escape compressor as 2 bytes per surrogate pair, and 60 bytes in the image manually packed into the string "o" with 20 bits per surrogate pair + 4 chars for variable assignment outside)... :) yay i'm learning about arcane UTF16 stuff.

the distribution is biased af

I mean maybe it is a coincidence but it's deterministic, so it better be more random in the first place
