Markdown support

[Bengt]

Currently Atom Beautify displays an error, when opening a markdown file:

Unsupported language for grammar 'GitHub Markdown'.

It would be nice to have Atom Beautify normalize Markdown. That could be done using pandoc as suggested in another repo:

$ pandoc -f markdown -t markdown index.md

Thanks for posting a potential solution using pandoc. That really helps with potential features being developers, so I do not have to search around and hope it works for everyone.

This would not be very hard to do at all given we already have a cliBeautify base class and many other beautifiers that use external CLI tools.

[Bengt]

You are very welcome. Let me know if there are any questions about using pandoc. Would it be preferable to read from a file rather than from stdout? That could be done by specifying one using the -o / --output flag:

$ pandoc -f markdown -t markdown -o index_new.md index.md

[Glavin001]

Reading in and out from file would be better than stdin and stdout.
Here is an example: https://github.com/Glavin001/atom-beautify/blob/master/lib/langs/php-beautify.coffee
You could simply swap out the command from php_beautifier to pandoc and change some of the arguments and you'd be done 👍

OK, I will give that a shot.

[Bengt]

Gave that a shot and (to my surprise) succeeded. Please test the referenced pull request.

Published to v0.12.0

If you want to get rid of the pandoc dep, I wrote a markdown beautifier in pure JS: https://github.com/slang800/tidy-markdown (so it can be required via npm)

[Glavin001]

Awesome! Could you open an issue for this? I'd like to add support for tidy-markdown for Atom Beautify v1.0 😃
