I came up with the following. It basically is a pair of typing-saving
canned s/// command which replaces all consecutive horizontal whitespace
with a given number of linebreaks throughout the buffer, in a range or in
the current visual selection, in the second version restricted to
horizontal whitespace after sentence-final punctuation.
" Command :Wl [{N}] (*W*ord *l*ine)
" Replace consecutive horizontal whitespace in buffer/range/selection
" with N line breaks (Default: the number in variable g:Wl_line_breaks)
let g:Wl_line_breaks=1
:com! -range=% -nargs=? Wl exe
printf(',s/\s\+/%s/g',repeat('\r', ( ? :
g:Wl_line_breaks)))
" Explanation:
" -range=%
" The command operates over the whole buffer or over a given range,
which
" may be visual.
" -nargs=?
" The command takes an optional argument.
" exe printf(...)
" Constructs a string containing the actual command, then executes this
" string as a command.
" ( ? : g:Wl_line_breaks)
" Compute N: use the argument if there was one (and it was non-zero)
" or else use the number which is the value of the global variable
" g:Wl_line_breaks, which must be defined.
" It is up to you to make sure that the argument and the variable value
" are positive integers!
" repeat('\r', N)
" Construct a string which will be interpolated as N linebreaks.
" The string doesn't actually contain linebreaks, but they will "become"
" line breaks when the command is executed.
" s/\s\+/%s/g
" Here %s will be replaced with N linebreaks,
" so if N is 1 it's s/\s+/\r/g
" and if N is 4 it's s/\s+/\r\r\r\r/g
" so basically replace all consecutive horizontal whitespace
" with the desired number of linebreaks.
" Command :Sl [{N}] (*S*entence *l*ine)
" Replace consecutive horizontal whitespace *after a ./?/!*
" in buffer/range/selection with N line breaks (Default: the number in
variable g:Sl_line_breaks)
let g:Sl_line_breaks=1
:com! -range=% -nargs=? Sl exe
printf(',s/[.?!]\zs\s\+/%s/g',repeat('\r', ( ?
: g:Sl_line_breaks)))
" Explanation:
" This is basically the same as above, but requires that the horizontal
" whitespace is preceded with a "." or "?" or "!", and it has its own
" variable for the default value of N.
" Mappings to execute :Wl/:Sl (without argument) over buffer/selection
nor Wl :Wl
nor Sl :Sl

The commands above and the command from yesterday work on an existing or
previous visual selection too. If you have a visual selection and press :
the commandline is prefixed with '<,'> which is a range equal to the lines
holding the visual selection. You can also insert that range manually to
restrict a previously used command to the latest visual selection.
The mappings above work either on the whole buffer or the visual selection,
so just make a visual selection and type Wl and it just happens in the
visual selection.
In yesterday's installment the
vnor Jp :Jp
means that you can make a visual selection and just type Jp and have the
:Jp command applied to the selection. Just make sure that the selection
ends with a blank line. The
nnor Jp ...
line from yesterday does the same over the whole buffer in normal mode,
with the difference that it first inserts a blank line at the bottom of the
buffer to make sure there is one.

It's nothing. I have been using yesterday's command/mappings for ages, and
I will certainly use those from today too.

Re: Automating paragraphs (was Re: Dump help pages)
Thanks.
This is pretty complicated, but probably what I had in mind.
So, some basic clarification -
You defined a new command called Jp. You specify a line range, and it
starts at every non blank line and joins all following non blank lines.
That's quite good. Thanks very much.
What about the second command I had in mind? I could really use a way to
select a paragraph and insert N newlines between every Word (Vim "W") (and
also sentence, on a separate occasion), with a single command, say in
visual mode.
With your command, I can imagine it could be modified to start at every
Word and just append newlines. Do you think you could write an example of
this? And, how to use it on highlighted text in visual mode, instead of
specifying a line range?
Thanks very much,
Julius

A much more reasonable goal is to read appropriate _portions_ that answer your questions.

Re: Automating paragraphs (was Re: Dump help pages)
Thanks very much, really appreciate it.
Would you mind providing a simple outline of a function which would
terminate on some basic condition, such as, the next line is a blank
newline? I will read those docs.
I use Vim in Termux, an Android terminal emulator app. I don't know if I
have buttons such as F9. I will investigate it. However, is there a way to
check what non-F keys are free to be mapped to something? Thanks very much.
Best regards,

The short answer is go to the top of the paragraph and press Shift+V,
then to the bottom and press Shift+J (not Ctrl+J). You can automate this
further by writing a function that would figure out the top and bottom
of the paragraph via whatever logic you build in. See :help :function.

Example, for N = 4:
:imap
Type the actual < and > characters as shown. To use this, at the end of
typing your paragraph do not press Esc but press F9 (or whatever key you
mapped).
If you sometimes want to insert N blank lines in already-written text,
add this:
:map A
The previous map was active in insert mode; this one is active in normal
mode. It moves to the end of the current line ("A") in insert mode and
then appends the insert-mode version of F9.
Once you've verified that these work as you wish, you can put them in
your $VIM/_vimrc file so that they will be executed whenever you start Vim.

`` or ''
(One goes back to the _line_) where you were; the other goes back to the
exact position within the line.)
