Define

In MCScript, processing similar to C language define is possible by editing YAML. Describe the definition in define.yml in the same position as config.yml.

CON: "CONSTANT"

Defining a key and value replaces the string that matches the key in the script before execution.

Println("CON") # CONSTANT

In order to rewrite only the matching part of the script, it is necessary to enclose it with double quotations. If you want to treat it like a constant:

CON: "\"CONSTANT\""

Println(CON) # CONSTANT

You can also take an argument and embed it in a string.

INCREMENT(A): "A += 1"
CONCAT(S1, S2): "\"S1 S2\""

i = 0
Println(INCREMENT(i)) # 1
Println(CONCAT(hello, world)) # hello world

Spaces to the left and right of the argument are ignored.

Println(CONCAT( This is , my book.  )) # this is my book.
