My solutions to Advent of Code. Some solutions were either livestreamed or explained on YouTube.

• 2015 - APL complete (missing 4 as it requires MD5)

Also, https://everybody.codes is under the corresponding folder.

⎕IO is always assumed to be 0. Solutions developed iteratively in Sublime Text, using the Build system (see demo here).

Requirements:

• Dyalog APL
• Sublime Text
• APL package for Sublime Text

{ settings: {
	Default_IO: 0,
	Default_PP: 15,
	Default_PW: 32767,
	Dyalog_LineEditor_Mode: 1,
	MAXWS: "4G",
	Log_Size: "2M",
}}

Custom build system that relies on dyalogscript.

Note: replace with your own /PATH/HOME, ~/ for home directory doesn't work.
