Re: error: unknown escaped string: `\overlay

[Torsten Hämmerle]

Hi Pedro,

\overlay didn't exist yet in version 2.18.2.
It's a new markup command.

If you don't want to switch to a recent development version, you may replace
\overlay by \combine, since \overlay is a kind of \combine that can take a
list of arguments (instead of just only two).

In your example, incidentally, there are only two arguments so that \overlay
can be simply replaced by \combine to make it downward compatible (and don't
forget to remove the curly braces around the two arguments)

[...]
            \combine
                    \translate
                        #'(1.0 . 1)
                        \sans
                            \fontsize
                                #-3
                                \center-align
                                    \fraction
                                        1
                                        4
                    \translate
                        #'(151.0 . 1)
                        \sans
                            \fontsize
                                #-3
                                \center-align
                                    \fraction
                                        11
                                        8
[...]

HTH,
Torsten
