Filters

Filters allow you to transform template values using the pipe syntax: {value | filter}. You can chain multiple filters: {value | filter1 | filter2}.

Define filters using the --filters option with a JavaScript object literal:

$ echo '{name | uppercase | reverse}' | pupa --name=hello --filters='{uppercase: v => v.toUpperCase(), reverse: v => [...v].reverse().join("")}'

Common Filter Examples

{
	uppercase: v => v.toUpperCase(),
	lowercase: v => v.toLowerCase(),
	trim: v => v.trim(),
	reverse: v => [...v].reverse().join(''),
	length: v => v.length.toString()
}
