Markup extension for showing bullets line-by-line

[doherty]

Often, you might want to have bullets appear one by one on a slide. You can approximate that by copying the slide n times. The first copy has bullet 1, the second has bullets 1 and 2, and slide n has all bullets showing.

However, this is inconvenient because if you want to make changes to any of that content, you have n slides to change. As well, you have to manually arrange the slides with the right bullets displaying.

Instead, it would be helpful to have a way to specify that a section of text should appear line-by-line - perhaps a macro that expands to multiple slides as described above. Or do it with JS.

If you use two instead of three dashes when separating slides, the contents of the previous slide will be inherited by the next one. That way you can have a single bullet on each slide and have them all inherit the previous slide, effectively building a bullet list incrementally the way you describe.

Using two dashes to separate slides is a special case of the more generic template slide property.
