Argument validators (WIP)
You can specify some simple validations in the argument DSL.
Validators can also filter/normalize inputs, for example bool can take "yes" and set that as true.
Syntax
- Arguments can only have one validation applied to them.
- The Validate class provides some default validators and custom validators can be registsered.
- Validator args must not have spaces,
<arg: int min = 0>would be an error. - Validator/filter args should not be named
val, that'n conventionally used as the first function argument.Built in validators
uint, int, number
These all do what you would expect, check for types of numeric values.
They take two optional arguments min and max.
They will cast to the appropriate PHP type, for int or uint that is int numeric could be int or float.
Example:
bool
Can take "yes", "on", "true", "no", "off", "false" and returns a PHP bool
options/choices
This one lets you limit the argument to a few choices. To use an optional you only need to put options in parentheses with a | to separate choices.
Example:
Custom validators and filters
You can set your own custom validators:
You can set filters, these are what normalize values for you.
