@chrispsn i also have 100 project euler solutions and many code golfing ones, if you consider those representative enough

@ktye i guess it could work

ideally there would be flags, like in atw's k

@ngn with flags it's obvious what to do. this idea is about not having flags but still a good primitive.

@ktye i'll give it a shot. i hope you're not gonna sue me :)

that's no fun. i'd rather patent all primitives then sue kx.

i wish we had sane intellectual property laws (we = jurisdictions where the berne convention applies) and geniuses like atw weren't incentivized to be dicks

 \t ?{x@<x}100000?0 /before
1822
 \t ?{x@<x}100000?0 /now
5

@ktye ^

this feels rather special-casey though. what if we could use <x (which is very efficient) somehow to implement ?x

{x@&@[;0;1]x>x@i@-1+<i:<x}

@ktye ^this is ?x as a k-string. faster than my previous impl in the general case :)

definitely looks cool

@ngn definitely! Just wasn't sure how to approach it - maybe concatenation

oh! euler is a single file. sweet

here's the results gist.github.com/chrispsn/683758bfe7e34c6228af91464a33da3d

@chrispsn would be interesting to know how many + are addition and how many flip. i'm thinking about using +x for abs (because of complex numbers). doing the analysis based on the parse tree may be more complicated (to distunguish monadic and dyadic), given you have multiple k dialects as input.

@chrispsn nsl.com has some good k code - "view source", then search for ".k"

i'm sure i've seen k code on github.com too but it's hard to search for :|

@chrispsn for the golfing solutions, you'd probably be interested only in the first 2 lines of each file - the rest are tests

$ head -q -n2 ??*.k

^ ?? is there to ignore 0.k - the only single-char .k file

the first line of each file is a comment with the url of the codegolf problem. you can ignore those by appending | grep -v '^\/'

nsl.com (stevan apter's) can be all found in nsl.com/k - no need to view-source; and curl/wget can mirror it. However, be aware it is a mix of k versions (including a few of Apter's own versions).
