YAML Front Matter support in Markdown

[jackmaney]

So, I have the following markdown with YAML front matter (for use with Jekyll):

---
title: This is a title!

---

stuff

more stuff

When I beautify this, the front matter disappears:

stuff

more stuff

Adding GitHub Markdown to the disabled languages prevents the front matter from being eaten. However, it would be nice to have the beautification work.

Thank you for your time.

There are currently no beautifiers (that I have found) that support YAML Front Matter.
Possible solutions: detect that the file contents begins with YAML Front Matter, and if so, remove it from contents, beautify contents, and then prepend the YAML front matter to the post-beautified contents. This should work well.
No ETA on this functionality right now. Thanks for making this issue!

• Add package option for enabling YAML Front Matter
  • I doubt this will add too much of a performance hit to the Markdown beautifier, so let's make this setting default to True so future users will not be shocked when it does not work out-of-the-box.
• If YAML Front Matter is enabled, on Markdown beautification,
  • first process with https://github.com/dworthen/js-yaml-front-matter and then take the __content and pass that to the Markdown beautifier
  • take the result of Markdown beautifier of __content and concat the YAML Front Matter to the top and return that result

I started working on this however I realize now that the cli-beautify base class is not very customizable and does not meet the requirements I have for this feature. I think completing #164 should come first as it will force me to redesign how CLI-beautifiers are handled and now I can start brainstorming an improved API for supporting existing and adding more CLI-beautifiers in the future.

I will definitely update this after #164, however it is at least working now and you can use it while I develop out #164.

The build is failing for release v0.20.0.
See https://travis-ci.org/Glavin001/atom-beautify/builds/45655633
I think this is because of dworthen/js-yaml-front-matter#2
Until that issue has been resolved, I may have to disable / remove this feature. @jackmaney could you please update and check for yourself if it is working? Thanks.

[Glavin001]

Fortunately it looks like the YAML Front Matter library wraps js-yaml, so I can remove js-yaml and use yaml-front-matter instead.

Published to v0.20.1! Enjoy 😃

[jackmaney]

Awesome. Thank you so much! :D

Hmmm, strangely enough, the same exact before and after in the opening comment is still occurring:

Before

---
title: This is a title!
---

stuff

more stuff

After

stuff

more stuff

[Glavin001]

That's very strange. Travis CI already OKed the unit test for the more complex case. I'll have to take another look once I'm home.

I'm home now. I am still receiving correct results for both of those tests. @jackmaney, could you run command Window: Reload and / or uninstall and reinstall Atom Beautify?
