- The proxy is not a helper, we want the helpers folder to only include helpers - The proxy is also meant to be the interface to Ghost for the helpers, and we want to enforce that - This is a small step on the way

// # Plural Helper
|
|
// Usage example: `{{plural ../pagination.total empty='No posts' singular='1 post' plural='% posts'}}`
|
|
// or for translatable themes, with (t) translation helper's subexpressions:
|
|
// `{{plural ../pagination.total empty=(t "No posts") singular=(t "1 post") plural=(t "% 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+
