Visually-Interlaced Mesmerizing Japh

This Japh needs gvim 7.0 installed. (Note that it has to be version 7.0; earlier versions won't support the scripting commands used).

When I wrote this Japh, I didn't know any vim-scripting, so I had to take a more basic approach. Shortly afterwards I devised the algorithm for this one, and thought if I could learn enough vim scripting commands, it shouldn't take more than a couple of days to program. Surprisingly, it took a lot longer than expected, but partly because, as it evolved, I kept wanting to get it "just right". One challenge was "golfing" the vim script to make it all fit into the Japh. (If you know any vim commands, you'll see a lot of command abbreviations :-D).

It's been tested on both Windows and Linux. When you get tired of watching it run, just type ^C to stop. It does create a temp file "v.tmp" which can be deleted afterwards. If there's any interest, I may also provide the "meta-program" which generates the Japh. Of course, it would be fun to see if anyone can figure out the mechanics of how it works first.

I haven't finished exploring the encoding mechanism, but here's a basic summary. Each group of 3 characters is used in the creation of one output character. The character code is generated by summing the following: `chr( 5 * ( 5 * l($char1) +l($char2) ) + l($char3) + 2 )` [download] Where 'l' is a subroutine that does: `int ( ord($char) - 42) / 16` [download] Here is the translation for the first 11 sets: [::j] chr(2+5(5l(:)+l(:))+l(j)) = chr(5(51+1)+4+2) = $ [jJj] chr(2+5(5l(j)+l(J))+l(j)) = chr(5(54+2)+4+2) = t [J:r] chr(2+5(5l(J)+l(:))+l(r)) = chr(5(52+1)+4+2) = = [BBR] chr(2+5(5l(B)+l(B))+l(R)) = chr(5(51+1)+2+2) = " [scC] chr(2+5(5l(s)+l(c))+l(C)) = chr(5(54+3)+1+2) = v [C[k] chr(2+5(5l(C)+l([))+l(k)) = chr(5(51+3)+4+2) = . [kKj] chr(2+5(5l(k)+l(K))+l(j)) = chr(5(54+2)+4+2) = t [j:J] chr(2+5(5l(j)+l(:))+l(J)) = chr(5(54+1)+2+2) = m [jJ] chr(2+5(5l(j)+l(J))+l()) = chr(5(54+2)+0+2) = p [>>N] chr(2+5(5l(>)+l(>))+l(N)) = chr(5(51+1)+2+2) = " [N>N] chr(2+5(5l(N)+l(>))+l(N)) = chr(5(52+1)+2+2) = ; [download] Which yields: `$t = "v.tmp";` [download] This encoding gives a great deal of flexibility in the characters used, as every column is divided by 16 before it is touched by the decoder. The resulting perl script is as follows: $t="v.tmp";open($f,">$t"); print $f " let L=[\"[][+/13579;=?_acegikmoqsuwy-]\",\"[],014589<=@%`adehilmpqtuxy +-]\",\"[/.016-9>?@^_`af-in-qv-y]\",\"[2-9b-ir-y]\",\"John C.

Pretty darn cool. I don't know VI very well and script at all, so not even trying to decipher this :) But definately enjoyed watching it! Purdy colors! ++ s&&VALKYRIE &&& print $_^q\|!4 =+;' *\|	[reply]

This is one of the most colorful japhs I've seen. I'll be taking a close look at this one later to see how you managed to pack so much information in only a page full of text. ++Excellent work!	[reply]
