Placeholders

Basic Operations

• Addition | <expr_add:n1:n2:...:nX>
  • <expr_add:5:2:3> == 10
• Subtraction | <expr_sub:n1:n2>
  • <expr_sub:10:3> == 7
• Multiplication | <expr_mul:n1:n2:...:nX>
  • <expr_mul:5:2:3:6> == 180
• Division | <expr_div:n1:n2>
  • <expr_div:10:5> == 2
• Division remainder <expr_mod:n1:n2>
  • <expr_mod:5:2> == 1
• Negation | <expr_neg:n>
  • <expr_neg:5> == -5
  • <expr_neg:-5> == 5

Round

• Round down to integer | <expr_floor:n>
  • <expr_floor:5.05> == 5
  • <expr_floor:2.9> == 2
• Round to nearest integer | <expr_round:n>
  • <expr_floor:5.05> == 5
  • <expr_floor:2.9> == 3
• Round up to integer | <expr_ceil:n>
  • <expr_floor:5.05> == 6
  • <expr_floor:2.9> == 3
• Get the lowest-valued number | <expr_min:n1:n2:...:nX>
  • <expr_min:5:10:15:2:500:9:69> == 2
• Get the highest-valued number | <expr_max:n1:n2:...:nX>
  • <expr_max:5:10:15:2:500:9:69> == 500
• A random number from 0 to 1 | <expr_random> | Acts like <expr_random:0:1:0.01>
  • <expr_random> == 0.15
• A random integer from min to max | <expr_random:min:max> | Acts like <expr_random:min:max:1>
  • <expr_random:1:100> == 69
• A random number from min to max with a step of step | <expr_random:min:max:step>
  • <expr_random:50:10:0.25> == 68.75

String Operations

• Concat strings | <expr_concat:s1:s2:...:sN>
  • <expr_concat:hello:_:world> == "hello_world"
• Create a substring of s from n1 to n2 character | <expr_substring:s:n1:n2>
  • <expr_substring:hello:2:4> == "ll"
• Get length of the string | <expr_length:s>
  • <expr_length:hello> == 5
• Format a string using Java String.format() | <expr_format:format:arg1:arg2:...:argX>
  | It may be useful for user expressions
  • <expr_format:'%s is not a %s':4drian3d:fruit> == "4drian3d is not a fruit"
• Displays r1 if o1 and o2 are same. Otherwise, displays rs | <expr_if:o1:o2:r1:r2>
  • <expr_if:1:2:Equals:NotEquals> == "NotEquals"
• Sets text placeholders for a player with uuid. | <expr_player:uuid:text>
  • <expr_player:4drian3dUUID:<player_name>> == 4drian3d
• Sets text placeholders for a player with name. | <expr_player:name:text>
  • <expr_player:4drian3d:<player_ping>> == 42
• Expand to a User expression | <expr_user:name:arg1:arg2:...:argX>

User expressions

You can create your own expression shortcut in expressions.properties using our Expression Provider Language (EPL):

add_and_multiply=<expr_add:"<arg1>":"<expr_mul:'<arg2>':'<arg3>'>"> means <expr_user:add_and_multiply:arg1:arg2:arg3> will be evaluated to arg1 + (arg2 * arg3).
So, <expr_user:add_and_multiply:2:3:4> evaluates to <expr_add:2:'<expr_mul:3:4>'>, which is 2 + (3 * 4) = 14

Example user expressions

• <expr_user:remove_first:s:n> - Remove n first characters from s (hello, 2 -> llo), EPL: remove_first=<expr_substring:"<arg1>":"<arg2>":"<expr_length:'<arg1>'>">
• <expr_user:remove_last:s:n> - Remove n last characters from s (hello, 2 -> hel), EPL: remove_last=<expr_substring:"<arg1>":0:"<expr_sub:'<expr_length:"<arg1>">':'<arg2>'>">
• <expr_user:decimals:n:decimals> - format a number (1.234567, 2 -> 1.23), EPL: decimals=<expr_format:"<expr_concat:'%.0':'<arg2>':'f'>":"<arg1>">
• <expr_user:pad_integer:n:length> - pad an integer with zeros (12, 3 -> 012), EPL: pad_integer=<expr_format:"<expr_concat:'%0':'<arg1>':'d'>":"<arg2>">

Nesting

Expressions can be nested. Try /miniplaceholders parse me <expr_add:1:"<expr_add:1:'<expr_add:1:"<expr_add:1:'<expr_add:1:0>'>">'>">
