Introducing SAL, an alternate syntax for working with CM and Lisp. Sal
provides commands, statements and infix sexprs. SAL has its own
lexer/parser and combines features of lisp, dylan, pla and stella. Sal
comes with its own Emacs mode (sal.el) that provides syntax
highlighting and eval services via SLIME.

this is what sal code looks like (much prettier with syntax
highlighting!)
; i am a comment. the print command:
print list(1, 2 + 3, 4)
print "the value is: ", interpl( between(0.0,1.0), {0 0 50 1 100 0})
; the define command:
define variable hi = pi * random(2),
ho = list(hi,2,3)
define function foo(n)
loop with l = list()
repeat n
set l &= random(127)
finally return l
end
define process bar(n, r, lb, ub)
run repeat n
for k = between(lb,ub)
output make(<midi>, time: now(), keynum: k)
wait random(r)
end
; open and sprout commands
open "test.mid", versioning: #t
sprout bar(20,.1, 60, 90)
sprout list(bar(30, .1, 60,70), bar(20,.2,30,50)) at {0 1}
load "rts.sys", "midishare.sys"
open "midi-port.ms"
rts 1
sprout bar(20, .1, 60, 80)
;---
SAL is brand new so it may change a bit -- I would be greatful for
feedback and suggestions.
to try it out:
install the tarball where you put other cm systems
add (load "/path/to/sal/sal.el") to your .emacs file
start cm under slime and do (use-system :sal)
edit examples.sal, follow directions at top
