Just for the kicks, only actually saved 4 bytes. Still way off 184 for actual content

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!
