Re: Cannot pass number variable to \markup.

Hello, fellow music engravers.

I would like to pass a number variable to \markup, but my attempts are not working.

When I try to pass a number variable to \markup I get the following message:

"error: syntax error, unexpected NUMBER_IDENTIFIER".

Examples:

<code start> fontsize-number = #5 { c'1^\markup \fontsize \fontsize-number "text" }

<code end>

or,

<code start>

raise-number = #5 { c'1^\markup \raise \raise-number "text" }

<code end>

Could someone help me to comprehend how to do this?

That is... interesting, I wonder if we should treat it as a bug actually.

The thing is that

\markup \raise 5 "text"

does not work because "5" in markup mode is not a number but the raw string made of the digit character 5. Due to the internal way the backslash works, this extends to \raise-number, even though there is no reason in this case.

Anyway, use the form

\version "2.24.1"

fontsize-number = #5

{ c'1^\markup \fontsize #fontsize-number "text" }

where "#" switches to Scheme mode in order to access the variable, just like \markup \raise #5 ... uses Scheme to write the number.
