feat: Front Matter can be ignored from within Blade files

[clemblanco]

When using Jigsaw from Tighten, we leverage YAML Front Matter from within Blade files in order to enrich template files.

Description

When using this formatter alongside the Prettier plugin, it will try to format Front Matter parts, and corrupt it.

title: Blog
description: The list of blog posts for the site
pagination:
    collection: posts
    perPage: 4
---

@extends('_layouts.main')

will become

---

pagination:
collection: posts
perPage: 4
---

@extends('_layouts.main')

but the indentation is important with YAML, therefore the Front Matter section becomes invalid.

Motivation and Context

We would like to be able to use prettier-ignore-start, prettier-ignore-end, prettier-ignore, blade-formatter-disable-next-line, blade-formatter-enable and blade-formatter-disable from within Front Matter YAML comments, so this formatter can ignore it and keeps formatting the Blade file underneath the Front Matter block.

This way we could have:

---
# prettier-ignore-start
title: Blog
description: The list of blog posts for the site
pagination:
    collection: posts
    perPage: 4
# prettier-ignore-end
---

@extends('_layouts.main')

How Has This Been Tested?

• Threw unit tests here
• When using it on a vanilla Blade file
• When using it on a Blade file with a Front Matter block
