OK, Thunderbird messed with references to external pictures; and it
was a stupid idea to include pictures, I should have foreseen it.
So, here's a copy with external links instead:
==========================================
Recently I dediced to put the &ff option in my statusline. However, I
want to edit my files *always* in the unix format, even when I am on
Windows. For this reason, I want to have no message shown in the
status line if the file format is set to "unix" (`uncluttered' is the
word here). I want any other format displayed as an error (with red
background).
I wrote this code
:set statusline+=@%(\ %#ErrorMsg#[%{&ff!='unix'?&ff:''}]%*%)@
@ - my debugging begin and end of string markers, in order to be able
to "see" an empty string
%(...%) - grouping is used here to make the leading empty space and
the brackets disappear if the expression yields an empty string
Results:
- if &ff is set to 'dos' or 'mac', the status line is correct:
http://tinyurl.com/vim-statusline-dos
http://tinyurl.com/vim-statusline-mac
- if &ff is set to 'unix', the expression produces an empty string
('@@') followed by two superfluous red spaces:
http://tinyurl.com/vim-statusline-unix
(Note the same is true for empty &ff, in this case the 'else' branch
of the ternary operator comes into force.)
If I remove the '@' markers, just two red spaces are produced.
Strangely, if I put the brackets outside of the #ErrorMsg# code,
everything works perfectly:
:set statusline+=@%(\ [%#ErrorMsg#%{&ff!='unix'?&ff:''}%*]%)@
http://tinyurl.com/vim-statusline-alt-unix
However, that's not a good workaround - it is not exactly what I
imagined for [dos] and [mac] cases:
http://tinyurl.com/vim-statusline-alt-dos
This is not a top-priority bug, of course; but I would appreciate any insights.
Best regards,
Peter
