strip spaces on paragraph formatting

[Michael Iatrou]

Hi,

Formatting the following two lines:

fooSPACESPACE
bar

using gqap (or gq on a visual selection of them) will give:

foo bar

I there a way to customize its behavior, to merge arbitrary number of white
space at the end of the line to a single space character, so that in the
example above I get:

foo bar

TIA

Maybe by first using the following to suppress all whitespace at ends of
lines? (Note: In "mail" files, the single space at the end of the
dash-dash-space sig delimiter should be left intact, hence the TRUE path
of the :if.)

mark '
1
if &ft == 'mail' && search('^-- $', 'cn')
1,/^-- $/-1s/\s\+$//e
else
1,$s/\s\+//e
endif
''

Note: The second and last lines in the (untested) snippet above are
"naked ranges", they move the cursor to the corresponding line.

Best regards,
Tony.

There's no easy customization so you have to combine several commands.

TextFormat plugin adds a bit more automatic and intelligent
text-formatting commands. It's suitable for human languages and it does
what you asked for (removes extra spaces).

It is also possible to write a custom formatexpr function. See :help
'formatexpr'. I don't know if this is at all recommended, but I have
found that within this expression it is possible to use the 'gw'
command (:help gw) in order to fall back to the basic behavior.

A full formatexpr is pretty involved though...not at all easy.

i think you can simply use :'<,'>s/\s*$//g, and use J or gq to format
your text.
