Cutting tag (former "Is it possible to manually split "header" and "body" of blogpost?")

[prokher@…]

Hi!

I published some images into my blog and them took a lot of pages, I'd like to make only one visible in list of posts and others - be available under cutline. Is it possible to accomplish this with FullBlogPlugin?

Thank you.

It will be more useful to support cutting tag in post, like cut, to divide post in 2 parts. I really need that feature because we use FullBlogPlugin to discuss art in our projects.

I would also vote for this. I like [blog:cut] idea. This would probably be easiest to implement. And could also be additional way of going around wrong cuts in #3069. And maybe even #4358. (As this cut should also reset text formatting.)

I'm not sure if this is the same thing as what you have been discusing, but sounds similar to me ... I'd find it useful to have an option to hide images from the Recent Postings sidebar generated by [[BlogList]]`.

I needed a cut option in order to show previews of long posts. I decided to keep it simple so I set the rule that the first horizontal rule (WikiFormatting "----") is the cut point.

I then added a simple bit of code to fullblog_macro_post.html to slice the body when a horizontal rule is found. I've attached the patch I use.

Server refuses to accept the diff file: rejects it as spam. Same thing happens if I try to add it as text manually. user-friendly, not! In the following text the link element causes the wobble so I've manually edited the element name 'a' to 'b' - change that to make it work.

Implement cut at first horizontal rule ( spam-trap avoidance: to use patch do sed 's/<b/<a/')

Use cut_at.2.patch - it doesn't cut posts unless list_mode is true, which means single posts don't get snipped.
