Greetings all,
I'm trying to craft a function to apply a series of pattern-matching
substitutions to the file. So far I've got this in my .vimrc
function Scrub ()
:%s// /g
:%s/\s*$//g
endfunction
map :call Scrub ()
but it's not working, seems to complain about lack of line-endings.
Would someone help me out please?

Like Sven, I'm not sure what you actually want to do — it wouldhave been
simpler if you had just told us that, in plain English.
If you want to delete all end-of-line spaces, a simple substitute will
do the trick:
:%s/\s*$//
or even
:%s/\s\+$//e
the e flag avoids an error message if there are zero substitutions in
the whole file (none of your lines ends in whitespace). It is not
necessary in the first case because that will match on every line,
matching zero or more whitespace, as many as possible.
Also, what _exact_ error message do you get?
And there seems not to be a {lhs} in your mapping: after correcting your
function, you should rewrite the mapping as
:map <F4> :call Scrub()<CR>
— with <F4> or anything else as the first space-separated aregument,
meaning "what you hit to trigger the mapping", and <CR> at the end
meaning "the mapping generates an Enter key at the end" — the omission
of the <CR> at the end might be the reason why Vim complains about a
missing end-of-line, but I cannot be sure without the exact error message.
Best regards,
Tony.
