Re: line continuation with sed

[Pier Paolo Grassi <pierpaolog@xxxxxxxxx>]

When the buffer is on multiple lines there is this corner case (zsh 5.8):

E \  
cdcd↩

ie the space is on the first line but the eol marker is on the last line of the buffer, is there a POSTDISPLAY equivalent at row level?

echo $fpath

why the command is not found? Should I do something to load the functions from fpath?

thanks

Actually that implementation is kind of ugly.  I completely forgot
about this much prettier way:

show-trailing-space() {
  if [[ $BUFFER = *(' '|$' \n'*)
        || $PREBUFFER = *$' \n'* ]]
  then POSTDISPLAY=$'\u21a9'
  else unset POSTDISPLAY
  fi
}
zle -N show-trailing-space
add-zle-hook-widget line-pre-redraw show-trailing-space
add-zle-hook-widget history-line-set show-trailing-space
