You can append some keywords (that we will call meta keywords), each specific to a placeholder’s type, at the end of a placeholder in order to modify its return value and type.

<some.placeholder.{keywords}>

Each keyword has an

• Input Type, which is the placeholder type the keyword applies to
• Output Type, which is the placeholder type that can be created from the keyword’s returned value

Placeholder support is allowed in every place inside of meta keywords, so each keyword can also be another placeholder to be parsed

---

<caster.name.capitalize>

<caster.name> returns a STRING
Among all keywords for the String type, we are using the capitalize one, which has as an output a String type. This means that

• It is applied to a String value
• It does some form of conversion to its value (in this case, capitalizing every character of the string)
• It returns a String value

<caster.name.size>

<caster.name> returns a STRING
Among all keywords for the String type, we are using the size one, which has as an output an Integer type. This means that

• It is applied to a String value
• It does some form of conversion to its value (in this case, returning the length of the string)
• It returns an Integer value

---

Given that each meta keyword has a specific input and output type, it is possible to chain them together, obtaining a compound effect where each keyword coverts the previous value and pass the result to the following one

<skill.var.exampleString.substring{from=0;to=9}.size.add{amount=1}>

Among all keywords for the String type, we are using the substring one, which has as an output a String type. This means that

• It is applied to a String value
• It does some form of conversion to its value (in this case, extracting the first 10 characters from the string)
• It returns a String value

Among all keywords for the String type, we are using the size one, which has as an output an Integer type. This means that

• It is applied to a String value (which the substring keyword just returned)
• It does some form of conversion to its value (In this case, returning the length of the string, which we know will be between 0 and 10)
• It returns an Integer value

Among all keywords for the Integer type, we are using the add one, which has as an output an Integer type. This means that

• It is applied to an Integer value (which the size keyword just returned)
• It does some form of conversion to its value (In this case, adding a value of 1 to the integer’s value)
• It returns an Integer value
