In a markup like
\raise #0.5 "text example"
\raise
is actually represented by the raise-markup
function. The markup expression is stored as
(list raise-markup 0.5 (list simple-markup "text example"))
When the markup is converted to printable objects (Stencils), the
raise-markup
function is called as
(apply raise-markup \layout object list of property alists 0.5 the "text example" markup)
The raise-markup
function first creates the stencil for the
text example
string, and then it raises that Stencil by 0.5
staff space. This is a rather simple example; more complex examples
are in the rest
of this section, and in scm/define-markup-commands.scm.
