I'm having a mental block, how can I wrap a string via
substitute() ?
The following seems to do the trick for me:
echo substitute(str, '[[:print:]]\{,10}', '&\n', 'g')
This nearly works, but is doubling existing line breaks.
The application is this :version pretty-fier:
function! Str_wrap(str, len)
return substitute(a:str, '[[:print:]]\{,'.a:len.'}','&\n','g')
endfunction
I must be missing something...in your original post, you didn't
have any linebreaks in your sample str...thus my answer didn't
deal with them. ;)
If you have a multi-line string and want to do a wrapping as
something sorta like "gqip" would do (minus its internal
smartness about things like comment-leaders or mail-quote
characters),
echo substitute(@", '\([[:print:]]\{,10}\)\>[^[:cntrl:]]', '&\n',
'g')
seems to do something fairly reasonably kinda sorta close to what
I understand you to be describing. :)
