altos/scheme: Rename to 'scheme', clean up build

2017-12-05T18:30:32+00:00

Constant block is now built in a subdir to avoid messing up source directory. Renamed to ao_scheme to reflect language target. Signed-off-by: Keith Packard

altos/lisp: Switch to scheme formal syntax for varargs

2017-12-04T03:54:18+00:00

Scheme uses bare symbols to indicate a varargs parameter; any bare (i.e., not wrapped in a cons cell) parameter will get the 'rest' of the parameter list. This works for lambdas, nlambdas and macros. As a result, the 'lexpr' form has been removed as it is equivalent to a lambda with a varargs formal. Signed-off-by: Keith Packard

2017-12-01T10:30:50+00:00

altos/lisp: Add scheme-style bools (#t and #f)

2017-11-17T02:40:31+00:00
