YaPlaceholder

An extension plugin of PlaceholderAPI that can let you custom advancer placeholders.

Usage

Use placeholder %e_expression% to get a advance placeholder. ('e' means 'expression' i guess..)

Data Type

Integer	num	An integer.	int	255892
Decimal	num+(d|d|f|F)	A float number.	double	5663d

Operator

Arithmetic Operators

Note: In code, # (modulus) uses % to operate decimals but uses Math.floorMod to operate intergers.

Name	Chars	Priority	Example
Brackets	()	Supreme	%e_1+(1-1)% got 1
Addition	+	11	%e_1+2% got 3
Subtraction	-	11	%e_1-2% got -1
Multiplication	*	12	%e_1*2% got 2
Division	/	12	%e_1/2% got 0.5
Modulus	# (not %)	12	%e_1#2% got 1

Bitwise Operators

Note: Integer only, or a exception will be threw out.

Name	Chars	Priority	Example
Left shift	<<	10	%e_1<<2% got 4
Right shift	>>	10	%e_-1>>2% got -1
Zero fill right shift	>>>	10	%e_-1>>>2% got 1073741823
Bitwise and	&	7	%e_1&2% got 0
Bitwise XOR	^	6	%e_1^2% got 3
Bitwise or	|	5	%e_1|2% got 3

Logical Operators

Name	Chars	Priority	Example
Logical Not	!	20	%e_!true% got false
Logical and	&&	4	%e_true&&false% got false
Logical or	||	3	%e_true||false% got true

Assignment Operators

Note: Except '=='(equals) and '!=' (not equals) can compare string, other operators can only compare numbers.

Name	Chars	Priority	Example
Greater Than	>	9	%e_1>1% got false
Less Than	<	9	%e_1<2% got true
Greater Or Equals	>=	9	%e_1>=2% got false
Less Or Equals	<=	9	%e_1<=2% got true
Equals	==	8	%e_1==1% got true
Not Equals	!=	8	%e_1!=1% got false

Function

Basic syntax: function(param1, param2, ...)

toInteger (and other cast functions)

Params: Object value
Return the value casted to Integer type.
Example: %e_toInteger("192")>1%
Meaning: It will return true. String cannot compare to an Integer value, but with toInteger you can. Similar: toDecimal, toBoolean, toString, toObject

if

Params: Boolean bool, Object value1, Object value2
If the bool is true, return value1.
If the bool is false, return value2.
Example: %e_if(toDecimal(value("player_health"))>0,value("player_health"),"Dead")%
Meaning: If you installed the PlaceholderAPI extension player, it should return players' health when they are alive or return 'Dead' when they are dead.

switch

Params: Integer number, Object selections...
Return the selection of the number.
Example: %e_switch(1,"Hi, bob!","How are you?")%
Meaning: It returns 'How are you?'. (index count from 1)

value

Params: String text
Get the value for the placeholder api string.
Example: %e_value('player_health')%
Meaning: It will return the player's health.
