Back to scale diagrams. I'm still using the enhanced version I received, but I want to contribute something too for a change, but boy, am I wrong :-p. I end up needing help again.
I tried something on my own, but I don't get it working, probably because I just can't wrap my mind around scheme. I don't know why, I understand php, I can get things working in python, but scheme... I keep trying though :-). I think this might be practical material for a tutorial :-). First of all, I'm refering to this snippet: http://lsr.di.unimi.it/LSR/Item?id=790 It got enhanced by Klaus Blum to be able to change the numbering in the dots. What I want to change now is the amount of frets shown on the diagram. I can of course change it in the snippet, but I want to be able to change it by adding an argument, so I can get three different diagrams, with three different amount of frets, like: cmajor=\markup\scale-diagramm #'((5 3) (5 5) (4 2) (4 3) (4 5) (3 2) (3 4) (3 5) (2 3) (2 5) (2 6) (1 3) (1 5) (1 7) (1 8)) #7 #1 #1.5 #12 #7 defines the amount of notes in the scale (arg2) #1 defines that it should be the first note to start the diagram (start) #1.5 scales the diagram.(arg3) the last number would then be the amount of frets (here 12) (arg4) I tried to work by example and changed this: #(define-markup-command (scale-diagramm layout props arg1 arg2 start arg3 ) (list? integer? integer? number?) to this #(define-markup-command (scale-diagramm layout props arg1 arg2 start arg3 arg4) (list? integer? integer? number? integer?) (interpret-markup layout props (markup (#:override (cons 'size arg3 ) (#:override '(fret-diagram-details . ( (finger-code . in-dot) (number-type . arabic) (label-dir . -1) (orientation . landscape) (dot-radius . 0.4) (fret-count . arg4 ) (top-fret-thickness . 4))) #:fret-diagram-verbose (fret-from-list arg1 '() arg2 start )))))) but then I get this error: Preprocessing graphical objects...fret-diagrams.scm <0>: In procedure > in expression (> maxfret my-fret-count): fret-diagrams.scm <1>: Wrong type argument in position 2: arg4 Clearly it's an issue of 'type argument'. When I change fret-count to the actual integer 12 instead of the variable arg4, it works. It is probably something schemy I don't get... http://www.bartart3d.be/ On Twitter <https://twitter.com/#%21/Bart_Issimo> On Identi.ca <http://identi.ca/bartart3d> On Google+ <https://plus.google.com/u/0/b/116379400376517483499/> 2015-11-22 10:21 GMT+01:00 bart deruyter <[email protected]>: > Hey, > > thank you for the idea's.
