Data Pack Lang - High Level language for mcfunctions

This is a transpiler for an custom higher level language to minecraft commands

Example code

create store someStore

someStore[someVar] = 100

if someStore[someVar] == 100 {
  'say counter reached 100'
  'say will be reseted now'
  someStore[someVar] = 2 - 2
  if someStore[someVar] == 0 {
    'say someVar reseted'
  }
}

Will be transpiled to the working commands:

scoreboard objectives add a dummy
scoreboard players set b a 100
scoreboard objectives add c dummy
scoreboard players operation f c = b a
scoreboard players set g c 100
execute if score f c = g c run say counter reached 100
execute if score f c = g c run say will be reseted now
execute if score f c = g c run scoreboard players set j c 2
execute if score f c = g c run scoreboard players set k c 2
execute if score f c = g c run scoreboard players operation j c -= k c
execute if score f c = g c run scoreboard players operation b a = j c
execute if score f c = g c run scoreboard players operation k c = b a
execute if score f c = g c run scoreboard players set j c 0
execute if score f c = g c run execute if score k c = j c run say someVar reseted

Code examples

Store

Store is the basic type to handle data.
Create:

create store myStore

Set

myStore[myValue] = 10

Update

myStore[myValue] -= 5

Read

myStore[anotherValue] = myStore[myValue]

Calculations

Inline calculations are possible e.g:

myStore[test] = myOtherStore[test] + myStore[addThis] - myStore[subThis]

If-Statements

if myStore[valueA] < yourStore[valueA] {
  'say you have more than I'
}

Not

if not myStore[valueA] == 0 {
  'say valueA is not 0'
}

Own commands

Own commands must be declared with '

'say im a own command'

As

To execute as use as:

as '@e[type=minecraft:villager]' {
  'say I am a villager'
}

Custom prefixed scopes

To simplify functions custom scopes were introduced:

'execute at @a' {
  'say hi'
  'say im still here'
}

Will compile to:

execute at @a say hi
execute at @a say im still here
