Commander

What's New:

User Changes:

• Added the (data pack) expression library!

This feature allows adding common expressions to a library where each is identified using an Identifier.

{
  "replace": false, // Can be omitted.
  "expressions": {
    "test:cool_expression": "score * 2.5",
    "test:boolean_expression": "level.isDay && !level.isRaining"
  }
}

Later on, these expressions can be evaluated inside other expressions using the library container, like so:

sqrt(library.my_id:some_value) * library.my_id:other_value

Or in execute/scoreboard brigadier commands using cmd:library. Prefer using the library in Brigadier commands! It does not require parsing the expression in-place!

• Brigadier macros in JSON commands should now correctly fail on dangling braces.

Dev Changes:

• Added more javadoc to the api package.
• Removed evalex and mapping-io from pom.xml
• Added LongExpression. Similar to Arithmetica and BooleanExpression, but for longs!
• Tried to fix expression equality.
• Added missing 'parameter' methods to Arithmetica, BooleanExpression and BrigadierMacro.
• Added Expression.Result#NULL.

Other Changes:

• The mod should now fail with slightly better error messages.
• Inlined constant BooleanExpression instances.
