Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

plain ascii
ansi escape codes (16 colour codes with bold/italic and background)
256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
24bit true colour ("888" colours (aka 16 milion))

printf "\x1b[${bg};2;${red};${green};${blue}m\n"

Desugar Scala Expressions

Use the compiler

scala -Xprint:typer -e "class A(val i: Int)" prints the desugarred expression after the typer phase. Use scala -Xshow-phases to get a list of all phases.

Or use a macro in the REPL

Paste this into a REPL session or in a file loaded with the :load command:

	snippet template "Basic template" b
	\documentclass[a4paper]{article}

	\usepackage[utf8]{inputenc}
	\usepackage[T1]{fontenc}
	\usepackage{textcomp}
	\usepackage[dutch]{babel}
	\usepackage{amsmath, amssymb}

	\begin{document}

	# Zathura configuration file
	# See man `man zathurarc'

	# Open document in fit-width mode by default
	set adjust-open "best-fit"

	# One page per row by default
	set pages-per-row 1

	#stop at page boundries


	# zgen
	export ZGEN_RESET_ON_CHANGE=($HOME/.zshrc)
	source $HOME/src/github.com/tarjoilija/zgen/zgen.zsh

	if ! zgen saved; then
	echo "Creating a zgen save"

	zgen prezto editor key-bindings 'emacs'
	zgen prezto prompt theme 'sorin'

	# 0 is too far from ` ;)
	set -g base-index 1
