Thanks for the report. I found a comment about readline in
sys/unix/linux/Makefile that says take out -lreadline to disable command
line editing. There's also a -DREADLINE switch that's not used.
The story here is that XLisp has the ability to break a running
computation so you can look at the stack and see what's going on, then
resume. But XLisp does not have very nice line editing. You can hack the
line editing problem by linking with the readline library, but that
disables the runtime control because it buffers control characters. I'll
try to document some readline configuration options later when I'm
able to test them.
You asked about Common Music. (And thanks for getting the name right --
I slipped and referred to it as Common Lisp Music, which is not what I
meant). The short answer is no, there's not currently any way to target
Nyquist from CM. Nyquist now has patterns that are similar to those in
CM, but since XLisp has a different object system, programs in CM are
not compatible with Xlisp/Nyquist. CM has the ability to generate MIDI
in real time (modulo garbage collection delays) and introduces a process
construct. In contrast, Nyquist has a very different approach to
concurrency based on lazy evaluation, so again, there are some
The best way to connect CM to Nyquist would be to get CM to write score
files and translate them to Nyquist score files, or work with MIDI
files, which both CM and Nyquist can read and write.
