See Contributing Feature Requests for what information is required in a valid feature request. Specifically this request lacks a root problem and doesn't seem to be about coding / product development. We also can't enforce people knowing when to use such tags, so even having them doesn't really solve the problem of tv show spoilers.

Strange, I read the Contributing Feature Requests documentation prior to submission, and I figured I'd described the root problem as having revealed content that is context-sensitive with my example of a TV series spoiler. There are potentially more uses outside of TV series spoilers, and I don't think it's any less valid than something like Macros.

We don't consider the fact that feature is missing, and would be used, a root problem. Something along the lines of understanding how your company was operationally impacted by seeing/hiding a spoiler would be helpful.

It is not possible to do this in Remarkup. Remarkup is a tool that has various rendering targets, like text (email, notifications, diffs, etc) and we have no mechanic for it to hide information. We do have products specifically engineered for sensitive information (policies, passphrase).

Remarkup is extendable for local installs, you can build whatever you need and drop it into src/extensions, you can even share it on the Community Wiki. But in general it's hard for us to assign a priority to something that impacts only a single or small number of installs.

Putting something like a header maybe could help in the meantime?

It was the dish, the entire time, the dish had ran away with the spoon.

End Spoiler

Yeah, that seems like a valid solution, however the spoiler in question is still visible, and could get glimpsed at before reading the warning. It'll have to do for now.

It has no operational impact, other than unforgivable anger from coworkers, just a humble feature request.

I assumed Remarkup could simply flag a different style on text, something akin to Reddit's spoiler tags, where the block of text is blacked out, and when hovered, changes the text color to white so that it's readable over the black background.

Thanks for the information regarding extensions. I was unaware that it was locally extensible. Is there any documentation in regards to Remarkup extensions?

Is a pretty basic one, simple regex / replace. Write your CSS inline.

Thank you much, @chad

Forgive the initial pushback.
