Simple Average in Many Languages

This was an exercise to take a peek at some different languages using a simple algorithm.

Average is an interesting algorithm to compare languanges. It is simple, but has enough complexity to demonstrate some differences between the languages.

Average requires calculating two different summary statistics (sum and count), then combining those two (division) into a single number. An efficient solution would only traverse the collection of numbers once.

Each of these are written as a function that would be given a collection of numbers. Whatever a collection means in that particular language. Some languages have multiple solutions that might have different tradeoffs.

Syntax	Name	Description	Example	Output
+/x	Sum	Sum all value in x	+/1 2 3 4 5	15
-':x	Deltas	Pairwise differences in x	-':1 2 3 4	1 1 1 1
\|+x	Rotate matrix	Rotate x counterclockwise	\|+3 3#!9	(2 5 8;1 4 7;0 3 6)
x@<x	Sort	Sort x	{x@<x}@8 3 7 1	1 3 7 8
?x,y	Set union	Unique elements from x and y	?"abac","adob"	"abcdo"
x^x^y	Intersection	Common elements from x and y	{?x^x^y}["abac";"adob"]	"aba"
x\|-x	Absolute value	Absolute value of x	{x\|-x}@-1	1
*/y#x	Power	x in power of y (y>0)	{*/y#x}[2;5]	32
y@(#y)!x+!#y	Rotate left	Rotate y by x elements to the left	{y@(#y)!x+!#y}[3;"abcde"]	"deabc"

k tech tree

Thought experiment:

Which k primitives can be implemented as k-strings, reasonably efficiently, with a handful of 'native' built-ins?

Not verified to be in dependency order yet... may depend on the choice of 'fundamental' primitives. Need to do speed tests too.

k9 syntax (download via Shakti). Got a better way to write one? Feel free to comment, you'll be credited!

A leak-proof tee to the clipboard

This script is modeled after tee (see [man tee][2]) and works on Linux, macOS, Cygwin, WSL/WSL2

It's like your normal copy and paste commands, but unified and able to sense when you want it to be chainable.

This project started as an answer to the StackOverflow question: [How can I copy the output of a command directly into my clipboard?][3]

	;; This is based on a Dvorak keyboard layout and isn't
	;; very comprehensive. The purpose is just to demonstrate
	;; that you can create your own modal editing system in Emacs
	;; using only a little bit of code.
	;;
	;; After loading this file, you can use "M-\" to enter command
	;; mode (aka "normal-state").
	;;
	;; To exit back to "insert-state", press "i".
