Add option to disable pretty print through comments

[rohit-gohri]

prettyprint

Description

I'm using marko in some weird ways like dynamically opening and closing ul tags in a for loop:

		<if (openCondition)>
			$!{'<ul>'}
		</if>
		<if (closeCondition)>
			$!{'</ul>'}
		</if>

This is pretty printed to:

		<if (openCondition)>
			<ul>
		</if>
		<if (closeCondition)>
			</ul>
		</if>

Which doesn't work because it throws an error:
The closing "ul" tag does not match the corresponding opening "if(openCondition)>

Why

This would help increase usage of pretty print as a standard linting option, as projects that are not being able to use it because of some edge cases can disable it in the code itself for that edge case.

Currently I would have to make a custom script around this module and maintain a list of files to be excluded.

Possible Implementation & Open Questions

I propose adding something akin to eslint's disable-line/disable-next-line/disable-file comments that will tell pretty print to not change the corresponding part of the template.

Is this something you're interested in working on?

Yes
