Re: [layout tweaks] 1. fill-line

[Germain G. Ivanoff-Trinadtzaty]



Thank you Rune,

 

Your trick is just ...fine !
It looks very promising. I'm not sure I understand its _exact_
behaviour, or LilyPond's behaviour towards text layout tweaks,
but I post hereby the results of my investigations, starting
with your snippet.
Please have a look at the following source : I ask some questions
in the comments.

 

Oh, this _text_ layout issue may not be "hot" for _music_ typesetters ?
Anyway, I hope someone (many!) is involved in these artistic
considerations.

 

Best regards,
Germain

    % Here, the 'title' is output _almost_ at the center of the page
    % (with a little shift to the right) while the 'index' is put
    % 'gap' spaces away from 'title', on the left side.
    % => Is it possible to hit the _exact_ center for 'title' ?
    % => By the way, how to specify 'gap' in millimeters ?

 

    title = \markup \large \fill-line { \line {

            % '\large' is only used to highlight 'title' position

            % with respect to 'subtitle' pos.

    % I pointed you at a strange ...feature(?)...
    % in the first message of this thread :
    % "[layout tweaks] 1. fill-line"
    % Indeed, the next two lines are not equivalent.
    % Here, the second line is better than the first,
    % but still doesn't _center_ the 'subtitle' on the page
    % (it puts it the same way as the 'title')

 

    % exact center :

%   subtitle = #mySubtitle

 

    % a bit shifted to the right ; hits the same "center point"
    % than 'title' when (*) is inserted. (by chance ?)
    subtitle = \markup \fill-line { \fromproperty #'header:mySubtitle }
}

% Second version :

 

% This version produces _bad_ output.
% (uncomment the outside brackets to test it)
% (and don't forget to comment out the first version, above)
% => Is it possible to use "center-align" there ?

 

    myIndex = "№ 210"
    myGap = #8.0
    myTitle = "|AZERTYUIOP|"
    mySubtitle = "|AZERTYUIOP|"

 

    title = \markup \large \fill-line { \line {
