I am trying to define a function test that takes a string and returns
the value of the variable the string represents. For example, if aaa =
25, then bbb = \test "aaa" would be the same as bbb = \aaa.
If I use the eval-string command directly, it is working fine. When I
try to put it in a function, it comes up with the error wrong type as
below:
\version "2.18.2"
test =
#(define-scheme-function
(parser location raga)
(string?)
(format #t "Inside function raga = ~a ~%" raga)
((eval-string raga)))
abc = IamJustAText
ab = enna
ennac = parava
xyz = #(eval-string (string-append ab "c") )
#(format #t "1) abc = ~a xyz = ~a ~%" abc xyz)
% This prints: 1) abc = IamJustAText xyz = parava
par = abc
#(format #t "2) abc = ~a xyz = ~a par = ~a ~%" abc xyz (eval-string
par) )
% This prints ) abc = IamJustAText xyz = parava par = IamJustAText
xyz = \test #(string-append ab "c")
% This gives an error:
% document.ly:8:6: In expression ((eval-string raga)):
% document.ly:8:6: Wrong type to apply: "parava"
#(format #t "3) xyz ~a ~%" xyz)
% This is the end of this example program
