Datapack library
DPlib is a function library for datapack developed in mcfunction. It is designed so that you can directly include the module you want in your datapack, without worrying about performance or compatibility and without creating dependencies. It is designed for performance and simplicity, it can be used in any datapack requiring simple or complex functions while being as fast as possible.This library contains:
- dplib.math
- Number-theoretic and representation
- Power and logarithm
- Trigonometry
- RNG and LCG
- Other various functions - dplib.datetime
- Real world date and time
- Local time
- Time and duration calculation
- Time conversion - dplib.threading
- Code threading with contextual entities
- Hierarchical threading
- Scoreboard ID - dplib.benchmark
- Benchmarking for development only
How it works
You just need to import the module(s) you need (they work independently) into the data folder of your datapack, you then need to load it by executing this command at the beginning of your datapack load file :
function dplib.<module>:load
You may also need to tick the module, if so add this to the beginning of your tick file :function dplib.<module>:tick
To ensure proper de-installation, you must include this line in the uninstallation file :function dplib.<module>:uninstall
In general, the input scoreboard for parameters is `dplib.<module>.in` and the output scoreboard is `dplib.<module>.in`. The automatically managed variables are in `dplib.<module>.main`For example, you can calculate how far away the nearest cow is:
# Puts the player's coordinates in parameters of the function
execute as Someone store result score $x1 dplib.math.in run data get entity @s Pos[0]
execute as Someone store result score $y1 dplib.math.in run data get entity @s Pos[1]
execute as Someone store result score $z1 dplib.math.in run data get entity @s Pos[2]
# Puts the nearest cow coordinates in parameters of the function
execute at Someone as @e[sort=nearest,type=cow,limit=1] store result score $x2 dplib.math.in run data get entity @s Pos[0]
execute at Someone as @e[sort=nearest,type=cow,limit=1] store result score $y2 dplib.math.in run data get entity @s Pos[1]
execute at Someone as @e[sort=nearest,type=cow,limit=1] store result score $z2 dplib.math.in run data get entity @s Pos[2]
# Calculates the distance using a tool provided by this library
function dplib.math:tools/distance
# Displays the result above the player's hotbar
title Someone actionbar [{"text":"Nearest Cow : ","color":"red"},{"score":{"name":"$out","objective":"dplib.math.out"},"color":"yellow"},{"text":"m","color":"yellow"}]
Or you can simply get the real world timestamp live:
scoreboard players get unix_timestamp dplib.datetime.main
This library is made to be used with Data-pack Helper Plus extension, it is easier to find the functions thanks to the auto completion provided by the extension and a library of aliases.

One problem is that getting the timestamp this way is only done once per minecraft account per month. The timestamp is therefore get on loading and automatically updated every second with local time. That's why the timestamp is updated every tick, and why you don't need to call any functions to get it, but only get it from a scoreboard, and why there's a huge 1Mb file containing 8192 minecraft accounts, in the hope that nobody reloads their world more than 270 times a day.
And if you're just looking to get that value because I may have misstated it in the doc, here you go:
scoreboard players operation $timestamp dplib.datetime.in = unix_timestamp dplib.datetime.main
function dplib.datetime:conversion/timestamp_to_datetime
and you can display it like this
tellraw @a ["",{"text":"year = "},{"score":{"name":"$year","objective":"dplib.datetime.out"}},{"text":"\nmonth = "},{"score":{"name":"$month","objective":"dplib.datetime.out"}},{"text":"\ndate = "},{"score":{"name":"$date","objective":"dplib.datetime.out"}},{"text":"\nhour = "},{"score":{"name":"$hour","objective":"dplib.datetime.out"}},{"text":"\nminutes = "},{"score":{"name":"$minutes","objective":"dplib.datetime.out"}},{"text":"\nseconds = "},{"score":{"name":"$seconds","objective":"dplib.datetime.out"}}]
