[foo-devel] semitone reader extension

[martin r. <fo...@ru...>]

good evening again,

as stated earlier, the future versions of foo should get rid of the
special version of elk.

some obvious changes (exporting of the pow function) i mailed to the
new maintainer of elk, they were applied to the official elk release.

for the libreadline support, i'll either discuss with the elk
maintainer, too (perhaps it's possible to get readline support into
the official elk release), or we'll use a custom "front-reader"
solution like avango does.

one thing remains: the semitone extension ("12s").  this extension was
made deeply inside the elk reader and it's therefore not possible to
replace it with a "front-reader", since that affects the reader
mechanism in general (the readline-capable "front-reader" ist just for
keyboard input, while the semitone-extension must also be present when
reading a file e.g.).  otherwise, the reader extension is no scheme
standard, thus there will be no chance to get such an extension into
the official elk distribution.

i considered this issue with gerhard during his berlin trip.  the
cleanest solution would be:

using the standard reader, in other words: remove the semitone
extension from the reader, and replace it by a function (similar to
pitch->freq).

ramon: how often did you use the reader extension?  would it be very
complicated to replace all occurences of the semitone syntax by a
function (semi->ratio or whatever)?  since it's a simple text
processing, this task could be done by a sed-someliner, i think...

all the best,

martin
