Re: [abcusers] abcmac - BarFly-style abc macro preprocessor in Perl

The reason for this is that an ornament which sounds right on a half note is often wrong on an eighth. I'm confused now. Suppose I had definitions for `Mn' and `Mn2'. What would happen (a) for `Mc' (b) for `Mc2' (c) for `Mc4' in the body of a tune? The interesting point is whether the `n' includes a length or not. (a) and (b) will expand, (c) will not, since there is no macro definition for that length. 'n' does not itself include the length, but the length (if any) is part of the target string. What the current Barfly version does when it encounters a macro on a note with an accidental is to place the accidental on the first ocurrence of the principal note in the expansion. [...] BarFly doesn't do this; rather it expands the macros in reverse order to the order in which the definitions are listed. Actually, thinking about this some more, it would be possible to sort the macro definitions into order before expanding them, provided that you used a sort algorithm which is guaranteed not to change the order of elements which are the same size. Since the list of macros to be expanded is never going to be very big you could just use a simple bubble sort. I've put a version of abcmac which is fixed in these two respects on my web page at `http://anselm.our-isp.org/abcmac/abcmac'. Maybe we can get abc2midi to process the Goldberg Variations? We could try ... If there's the possibility of other programs handling the macros, I'll fix the V: fields to be inline once I release the next version of BarFly (the current version won't work with that syntax). The postscript programs will still only be able to display it with the ornaments written out in full, which is highly illegible. I wasn't able to test the script, unfortunately. I had installed a new hard drive in my machine and simply copied all my stuff over to it. MacPerl has got itself into a fankle and can't find its libraries any more (perl5lib not found in @IN), despite the fact that perl5lib is certainly there, and the correct pathname is in the preferences. I downloaded and installed a new version which comes as a single standalone application, with all the libraries compiled in, and that didn't work either, objecting to 'strict', right at the beginning of the script. Us Mac users don't have a lot of fun with perl. Every time I try to use it I end up concluding that it would be quicker to write a program in C or Pascal to do the job.

'n' does not itself include the length, but the length (if any) is part of the target string. So in (a) and (b) the replacement of `n' is `c', and any length specifications are taken from the right-hand side of the macro definition (the `target string', if I understand you correctly). This is what my current implementation does (phew). Actually, thinking about this some more, it would be possible to sort the macro definitions into order before expanding them, provided that you used a sort algorithm which is guaranteed not to change the order of elements which are the same size. Since the list of macros to be expanded is never going to be very big you could just use a simple bubble sort. It's no problem simply to do the replacements in reverse order of occurrence. Actually it simplifies my code considerably. The sorting business came in because my very first version processed the replacements in order of occurrence (rather than reverse order), which obviously didn't work with Jack's example, which was all that I had to go on at the time. I didn't know about the reverse-order constraint until later, and I'm perfectly happy with it if you are. As I said, the version on my web page does the reverse-order thing already. Us Mac users don't have a lot of fun with perl. Every time I try to use it I end up concluding that it would be quicker to write a program in C or Pascal to do the job. Yes, but you Mac users have BarFly to begin with. I could have coded the macro preprocessor in C (no Pascal, please ...) but it would have taken me a lot longer than the two hours or so that I have spent on it so far. Anselm -- Anselm Lingnau ..

[abcusers] Mirror of Joyce's book Old Irish folk music and songs
Hello, I've found this : http://www.g8ina.enta.net/joyce.zip at : http://www.g8ina.enta.net/irish.htm The P.W.Joyce ABC Set The Joyce Set Site closed, thanks to Allen Garvin for permission (I've only found 370 tunes) | Don't know, but it's a great loss. | The site contained ABCs of all the 842 tunes from Patrick Weston Joyce's | (1827-1914) book Old Irish folk music and songs. | Yeah; I wonder if we can find an email address for the site's owner? I did a quick check with a couple of search sites, but didn't find anything useful. Such old collections are good to have online. If we can find it again, maybe we should offer to mirror it. ___ Do You Yahoo!? -- Vos albums photos en ligne, Yahoo!

Re: [abcusers] abcmac - BarFly-style abc macro preprocessor inPerl
I'm confused now. Suppose I had definitions for `Mn' and `Mn2'. What would happen (a) for `Mc' (b) for `Mc2' (c) for `Mc4' in the body of a tune? The interesting point is whether the `n' includes a length or not. (a) and (b) will expand, (c) will not, since there is no macro definition for that length. 'n' does not itself include the length, but the length (if any) is part of the target string. I wonder if we need two different kinds of macro? I can see the point of having the length-dependent ones, for the original purpose you had in mind (ornamentation) but the macros I've written have been about 50:50 ornaments and chords, and for chords the length-dependence is just a nuisance. The problem is that since the point of macros is to abbreviate, you want them to have very short names, which means you have very few options if you want those names to be at all mnemonic. You can't multiply them at will. Maybe it would be better to allow macros to select different behaviour for different lengths by a pattern-matching or conditional construct? That way you could reuse the same name for conceptually identical constructs (trill or mordent on different lengths of note). I wasn't able to test the script, unfortunately. MacPerl has got itself into a fankle [...] Us Mac users don't have a lot of fun with perl.

I think I've got three versions of MacPerl sitting around on my machines and none of them ever worked. Python anybody? That does work on the Mac.

If you just want a quick-n-dirty preprocessor prototype I could probably make one if I know exactly how the inputs and outputs are to be formatted. -D To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html
