Redefining paragraph text object?

[Silas Silva]

Hello all.

I was working around a function to map } and { around it. It is useful
for file formats that have other definitions of paragraph other than ^$.
For DocBook, for instance, it is better to use "<para>" and "</para>".

So I thought: it works for navigation, but not for all other operations
regarding paragraph text object. Would it be possible to change
paragraph text object for my own needs?

There is the 'paragraphs' option, but it look too simple, not accepting
regexp. I couldn't extend it far from the basic nroff setting.

Is it possible?

Thank you.

Hi Gary!

Not built in, but you can of course map { } to something different.
There are several text-object motion scripts at vim.org, this one here
seems to specifically take care of paragraph motion:
http://www.vim.org/scripts/script.php?script_id=3952

Disclaimer: I don't know the plugin and can't say how well it will work
in your case.

regards,
Christian

Mappings will work to change the behavior of { and }, but by "other
operations regarding paragraph text object," I assumed the OP was
referring to commands using ap and ip. There is no way that I know
of to change the behavior of commands using those.

I think that's what's addressed by this todo item:

- Add regex for 'paragraphs' and 'sections': 'parare' and 'sectre'.
Combine the two into a regex for searching. (Ned Konz)

I knew I'd seen something like this on the horizon. I'm just
surprised that it hadn't already landed�it's one of those sore spots
I've grumbled about since the 5.x days of Vim.

I see there is a todo entry. Working on that. It doesn't look hard
(just add more options and one more case for startPS() in search.c). I
will submit patch later. Thank you.

Then one can define visual maps and operator maps. In one of my plugins
I have:

vmap ip <Plug>SelectCurrentParagraph
omap ip :normal vip<CR> " omap, not onoremap

Similarly for ap. The <Plug>SelectCurrentParagraph is just a map which
selects a paragraph (I think I din't have to write this ;)

Hi Gary!

Yes, but you could omap those text-objects as well. The wiki has
something on that:
http://vim.wikia.com/wiki/Creating_new_text_objects

That would be nice as well. I already thought about a patch, but never
really got around in implementing that (and it probably takes a very
long time, until Bram includes it. Look into the todo-list, how many
patches are lying around.)
