* altos/scheme: Rename to 'scheme', clean up buildKeith Packard2017-12-05
| | | | | | | | | 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 <keithp@keithp.com>
* altos/lisp: Add 'big' ints -- 24 bits wideKeith Packard2017-11-18
| | | | | | | With the default ints being only 14 bits, having a larger type with more precision seems useful. This is not exposed to the application. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Finish first pass through r7rsKeith Packard2017-11-17
| | | | | | | | | | * print -> write, patom -> display * Add read-char, write-char * Add exit, current-jiffy, current-second, jiffies-per-second * Add for-each and string-for-each * Avoid duplicate builtins with different atoms Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lisp: Change lisp objects to use ao_poly everywhere. Add constKeith Packard2017-02-20
| | | | | | | | | | | This makes all lisp objects use 16-bit ints for references so we can hold more stuff in small amounts of memory. Also adds a separate constant pool of lisp objects for builtins, initial atoms and constant lisp code. Now builds (and runs!) on the nucleo-32 boards. Signed-off-by: Keith Packard <keithp@keithp.com>
