# DOCKER_DISPLAY ?= 192.168.1.63:0

build:
	docker build -t coursera/princeton-algorithms-p1 .

bash:

X11.md

For X11 forvarding (visualisation)

On linux - just set $DOCKER_DISPLAY to $DISPLAY (or unix$DISPLAY), not tested

On mac:

• install socat and xquartz:

brew install socat
brew cask install xquartz

• open xquartz
• launch socat

socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

• (in separate session) set up $DOCKER_DISPLAY

export DOCKER_DISPLAY=$(ifconfig|grep -E inet.*broad|awk '{ print $2; }'):0

@ro31337 missed notification. Yeah, there was extra linebreak. Fixed
