ZPT-JS tutorial - Formatters

A formatter allows to format the evaluation of an expression. ZPT-JS includes some formatters:

• format: lowerCase 'Test' evaluates as 'test'
• format: upperCase 'Test' evaluates as 'TEST'
• format: fix 1.371 2 evaluates as '1.37'
• format: fix (/: 1 3) 2 evaluates as '0.33'

You can register other formatters of your own:

context.registerFormatter( 
    'myCustomFormatter', 
    function( value ){
        return "$" + value;
    }
);
                

After registering it you will be able to use it as usual:

• format: myCustomFormatter aNumber

It is possible to run custom formatters without registering them. They must be functions defined in the dictionary:

• format: customFormatter aNumber formats aNumber using a function in the dictionary called customFormatter
• format: customFormatterName aNumber formats aNumber using a function in the dictionary called as the value of the customFormatterName variable
