- currently, the plural helper doesn't replace % with the number when the number is zero, which is inconsistent - this change ensures that theme developers can choose to show the number or a plain string

// # Plural Helper
|
|
// Usage: `{{plural 0 empty='No posts' singular='% post' plural='% posts'}}`
|
|
//
|
|
// pluralises strings depending on item count
|
|
//
|
|
// The 1st argument is the numeric variable which the helper operates on
|
|
// The 2nd argument is the string that will be output if the variable's value is 0
|
|
// The 3rd argument is the string that will be output if the variable's value is 1
|
|
// The 4th argument is the string that will be output if the variable's value is 2+
