Re: define-markup-function problem

Hello all,

Ignore previous post… I figured it out!

For those who will find this in the future, the offending line

        (markup #:column (cons stringA stringB))))

needs to be
        (markup (#:column (stringA stringB)))))

In plain terms, the specific markup function — in this case, #:column — apparently needs to be "listed in" with the function parameters. The proper (test) function is thus

#(define-markup-command (test layout props stringA stringB) (string? string?)
        (interpret-markup layout props
        (markup (#:center-column (stringA stringB)))))

Hope this saves someone else some hairpulling!

p.s. Is there any way that this could be better explained in the docs? The examples on < Markup-construction-in-Scheme#Markup-construction-in-Scheme>
seem to suggest that my first attempt should be fine.
