ISSUE TYPE

• Docs Pull Request

COMPONENT NAME

docs.ansible.com

ADDITIONAL INFORMATION

Some results of some more random Ansible output (taken from docs and PRs). Uses the default colorful style, i.e. not the Ansible colors; it mainly shows that other stuff is also lexed correctly :)

I personally prefer the GitHub colouring, and we made sure that the previous lexer was using the GitHub colourset

[felixfontein]

@dagwieers do you mean for the JSON? For everthing else, I find the GitHub coloring somewhat ugly (see here for the diff examples as highlighted by GH).

[felixfontein]

Actually, the GH coloring for JSON looks pretty boring. Are you sure you want that?

[felixfontein]

I adjusted the tokens a bit, to make the output more similar to the faux YAML output from the linked page. Now it looks like this (I've used the Ansible CSS for the random output from above):

[dagwieers]

I like it more than the red/green we had before!

LGTM
