4 to 1 Dwitter Compressor - Up to 224 Characters! Read comments for instructions and limitations. #Compressor

u/KilledByAPixel

How to use: Replace s with your code and it will throw the compressed version! To uncompress use t?eval(O+=W[V.charCodeAt(I/2)>>I++%2*5&31]):I=O=""
u/KilledByAPixel

Limitations: Can only compress 32 unique characters, and some characters are not allowed including double quotes, I,O,W,and V.
u/KilledByAPixel

The values for V and W can be replaced directly in the uncompressor to save space.
u/KilledByAPixel

Example: s="for(c.width|=i=9;i--;)x.fillRect(400+i*99+S(t)*300,400,50,200)" compresses to t?eval(O+=";for(c.width|=9-)xlRe40+*S3,52"["𠒃񁔇񢖋񓗍񐇯򐃑񐙒򴵅򹋖񕷘󋢙򒭘󅪻󅮛󭫝򕠀".charCodeAt(I/2)>>I++%2*5&31]):I=O=""

Very nice. It kind of looks like a late-70s magazine ad. Pacman and drugs—your kids will love them!
u/cantelope

danny, sarcastic 'drugs for [your] kids' remarks and judgement about others' "sins" is all well outside the scope of this platform. Might want to get back to building and being supportive
