RE: Space after clef

[Fairchild]

Mats -

Thanks yet again.

The pointer to Scheme is enlightening.

I do find that some of the alist entries are required.

You mean 'ambitus', 'staff-bar' and so on? They are defined by the property
'break-align-symbol' for the respective layout objects. For example, the
'break-align-symbol' property for the object Ambitus is 'ambitus'. See also
the second link I provided in the previous answer.

The value is a Scheme list. However, if you just look at a few examples,
it's easy to grasp the pattern.

I just copied the default value of the list and changed the spacing to
next-note. The list covers a number of cases that often appear in normal
score, i.e. that a clef is follow by a key signature or a time signature or
a bar line or ... Of course, if you know that one of these cases never will
happen in your score, then there's no need to include it.

'alist' is short for association list, which is a common concept in LISP
related languages like Scheme. For comments, just use the comment syntax of
Scheme, i.e.

\override Staff.Clef #'space-alist = #'(
        ; Copy of the default values:
        (ambitus extra-space . 2.0)
        (staff-bar extra-space . 0.7)
        (key-cancellation minimum-space . 4.0)
        (key-signature minimum-space . 4.0)
        (time-signature minimum-space . 4.2)
        (first-note minimum-fixed-space . 5.0)
        ; Changed the default value 0.5 to 1.5:
        (next-note extra-space . 1.5)
        (right-edge extra-space . 0.5))

See the Scheme tutorial in the manual with its link to other Scheme
documention for more information.
