Auto compile LESS to CSS on write. Also will allow you to compile a parent script by putting /* lessc-parent: "main" */ on the top line
function LessToCss()
let match = matchstr(getline(1), '...lessc-parent: "\zs.\{-}\ze"')
if strlen(match) > 0
let current_file = match . ".less"
let filename = match
el
let current_file = shellescape(expand('%:p'))
let filename = shellescape(expand('%:r'))
endif

Create repeating function. Takes arguments from first call and repeat on each call there after.
function repeater(fn) {
var args = false;
return function() {
if(args === false) args = arguments;
return fn.apply(this, args);
}
};
function add(a, b) {

Demonstrates possible bug in child_process

Demonstrates possible bug in child_process

running node main.js will result in process.stdin.setRawMode being undefined and tty.setRawMode barfing 'Error: can't set raw mode on non-tty'

running node child-using-stdin.js will give the function as expected and give deprecation message rather than barf.

Component/Module Structure

By default the project.md file declares one SRCDIR as

SRCDIRS ?= main

Overriding this in local project Makefile didn't appear to change anything. This is because every src directory requires a component.mk
