## Meta Variable Placeholders
You can append some specific keywords at the end of a variable placeholder in order to tweak its return value, getting some special return based on the variable type
### All Variable Types
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.expires> | Whether the variable can expire |
| <{VariableScope}.var.{VariableName}.expiration> | The expiration timestamp for the variable |
| <{VariableScope}.var.{VariableName}.saved> | Whether the variable is saved |
| <{VariableScope}.var.{VariableName}.type> | The type of the variable |
### Location Variable Type
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.x> | The x component of the location |
| <{VariableScope}.var.{VariableName}.y> | The y component of the location |
| <{VariableScope}.var.{VariableName}.z> | The z component of the location |
| <{VariableScope}.var.{VariableName}.yaw> | The yaw component of the location |
| <{VariableScope}.var.{VariableName}.pitch> | The pitch component of the location |
| <{VariableScope}.var.{VariableName}.world> | The world of the location |
### Vector Variable Type
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.x> | The x component of the location |
| <{VariableScope}.var.{VariableName}.y> | The y component of the location |
| <{VariableScope}.var.{VariableName}.z> | The z component of the location |
### Set Variable Type
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.size> | The size of the set |
### List Variable Type
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.{Index}> | Returns the element of the list at the given index (must be an integer) |
| <{VariableScope}.var.{VariableName}.size> | The size of the list |
| <{VariableScope}.var.{VariableName}.first> | The first element of the list |
| <{VariableScope}.var.{VariableName}.last> | The last element of the list |
| <{VariableScope}.var.{VariableName}.reversed> | Returns the list with a reversed order |
| <{VariableScope}.var.{VariableName}.sorted> | Returns the list after sorting it |
| <{VariableScope}.var.{VariableName}.shift> | Returns the first element of the list and removes it from the list itself |
| <{VariableScope}.var.{VariableName}.pop> | Returns the last element of the list and removes it from the list itself |
### Map Variable Type
| **Placeholder** | **Function** |
|-----------------------------|-------------------------------------------------------------------------|
| <{VariableScope}.var.{VariableName}.{Key}> | Returns the value associated with the given key |
| <{VariableScope}.var.{VariableName}.size> | The size of the map |
| <{VariableScope}.var.{VariableName}.keys> | Returns a list of all the keys in the map |
| <{VariableScope}.var.{VariableName}.values> | Returns a list of all the values in the map |
## Target Placeholders
These placeholders will return whatever target selector has been used. For instance <target.name> + @NearestPlayer will return the name of the player closest to the casting mob. The following are only some of the placeholders that can have a `target` scope, and in general any placeholder that is also present in the [Caster Placeholder](#caster-placeholders) section will also work.
