- The original intention of the proxy was to collect up all the requires in our helpers into one place - This has since been expanded and used in more places, in more ways - In hindsight there are now multiple different types of requires in the proxy: - One: true frontend rendering framework requires (stuff from deep inside theme-engine) - Two: data manipulation/sdk stuff, belongs to the frontend, ways to process API data - Three: actual core stuff from Ghost, that we wish wasn't here / needs to be passed in a controlled way - This commit pulls out One into a new rendering service, so at least that stuff is managed independently - This draws the lines clearly between what's internal to the frontend and what isn't - It also highlights that the theme-engine needs to be divided up / refactored so that we don't have these deep requires

// # 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+
