Languages: Hack ??

[Burke-Knight]

I've noticed this in the Repo's Languages list: Hack
How can I get rid of that? The repo is PHP and CSS.

You've not provided a link to the repo where you are seeing this so I poked around your profile and I can see you've probably taken this from https://github.com/Burke-Knight/Blocks-Website-Template

The reason you are seeing this is because Hack and PHP share the .php extension and we use a heuristic to determine which is Hack and which is PHP:

linguist/lib/linguist/heuristics.yml

Lines 513 to 518 in ee9119e

	- extensions: ['.php']
	rules:
	- language: Hack
	pattern: '<\?hh'
	- language: PHP
	pattern: '<\?[^h]'

You have six .php files which don't actually contain any PHP or Hack code that match these regular expressions... in fact they don't contain any PHP code at all and are plain HTML - only index.php has any PHP and it is being detected correctly as PHP. As a result, things are falling through to the classifier and it's making a bad guess based on the PHP and Hack samples we have.

There are three solutions:

1. Add PHP to those files, even if it's just a <?php // Comment ?>, so they're really PHP files.
2. Rename the files to use .html extension (as that's all they contain) and use readfile() instead of include() in your index.php file.
3. Leave everything as-is and implement an override to force the language to PHP but be warned, you'll get PHP syntax highlighting on those HTML-only files which may not always be correct.
