Side-by-side PP/MC texture comparison¶

#!/bin/sh
# needs imagemagick's montage (apt install imagemagick)

List all PRs since MCL2 release¶

#!/bin/sh
# create a markdown list of all PRs since mcl2 release (or since issueid)

release=3644 #issue id of mcl2 release
git ls-remote mcl2 'pull/*/head' |grep "pull/$release" -A 500000 |cut -d '/' -f 3 | while read pr; do

Print superfluous fields in node definitions¶

-- put at the end of builtin/game/register.lua to print superfluous fields in node defs
local old_rn = minetest.register_node
function minetest.register_node(name, def)
	local same = {}
	local same_found = false
	for k, v in pairs(def) do
		if type(v) ~= "table" and type(v) ~= "function" then
			if v == core.nodedef_default[k] and k ~= "type" then --type often gets copied when modified nodes are made from existing defs
				same[k] = v
				same_found = true
			end
		end
	end
	if same_found then
		print("superfluous node def fields for "..tostring(name)..":")
		print(dump(same))
	end
	return old_rn(name, def)

Calculate code size difference between MCLA and VL¶
