Hi all, I have problems getting fret-diagrams working in Lilypond+ConTeXt. The following works in lilypond \markup \fret-diagram #"s:0.75;f:1;6-x;5-x;4-o;3-2-1;2-3-3;1-2-2;" However, the following does not work in ConTeXt: \usemodule[lilypond] \starttext \startlilypond \markup \fret-diagram #"s:0.75;f:1;6-x;5-x;4-o;3-2-1;2-3-3;1-2-2;" \stoplilypond \stoptext I have ConTeXt ver: 2007.08.08 14:35 MKII fmt: 2007.8.26 int: english/english Lilypond version 2.10.5 and the Lilypond ConTeXt module t-lilypond-2007.09.02.zip The examples on the wiki works well, and the problem seems to be that \fret-diagram is written as \fret -diagram (note the space) in the .tmp file, and thus producing the error(?) Any ideas? Best regards, Micke P
Any ideas?
This is a catcode problem. Surround \start ... \stoplilypond with \catcode`\-=11 and \catcode`\-=12 Then you will probably experience a Lilypond problem because the line of code you type (\markup \fret-diagram ...) apparently isn't a legitimate Lilypond stand-alone score and you need to place it on the page with \mark, for example. But even then Lilypond is not so happy and complains that there is no note on the page, and you'd better put some there. To sum up, the following works for me: ---- cut after \usemodule[lilypond] \starttext \catcode`\-=11 \startlilypond d'' ^ \markup { \fret-diagram #"s:0.75;6-x;5-x;4-o;3-2;2-3;1-2;" } \stoplilypond \catcode`\-=12 \stoptext ---- cut before Have fun! Note for Hraban: this problem is apparently special to markups, that somehow the minus signs loses his letterhood when used in a markup. The fault lies obviously with Lilypond, since when I try to compile the following exact line (with the added curly braces): { \markup \fret-diagram #"s:0.75;f:1;6-x;5-x;4-o;3-2-1;2-3-3;1-2-2;" } Lilypond seems to suddenly forget that the minus is part of the command and complains about an “unknown escaped string: `\fret'”. I have no idea what to do in t-lilypond to fix it. Maybe you know? Arthur

Sorry, the catcode code is not by me, and I understand it only partly - I'm able to write PostScript and a lot of other languages, but TeX and Scheme are too obscure for me. Perhaps we can re-implement the module in Lua... If you come up with a fix, I'll gladly put it in the module. (There's still a lot more to be fixed/extended; since I'll have to finish my songbook soon, I'll have to cope with some of that...) Greetlings from Lake Constance!

Arthur, tanks for your kind reply! I'll try it when I get home. It was a bit confusing with the - for me, but I should have tried the catcode solution! Actually, I want to typeset only fret-diagrams, no notes. Maybe I should look that up in the Lilypond manual (if it is possible). The lacking of {}'s was because of the error I got without them. Hraban, thanks for bringing a nice module! /Micke P

I guess you should. Look for the general documentation on markups because that's what you need here. As for the braces, it seems extremely weird to me and I have not been able to draw any general conclusion about it, but you may try. I've wikified the entire discussion, in the hope that someone could sort it out in the future. Arthur

For some strange reason it works here if I replace /catcode`/-=/@@letter by /catcode`/-=11 in t-lilypond.tex. Mojca

Should I change it in the module or is it not save? Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

I'm convinced it is very safe, but as far as I'm concerned I've not been able to reproduce this behaviour; could anyone please confirm what Mojca says above? Arthur
