* altos/scheme: integer? is builtin on all versionsKeith Packard2017-12-12
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: inline some mem calls to reduce stack usage.Keith Packard2017-12-12
| | | | | | Also includes some code to display stack usage during collect calls. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Use direct calls from frame to frame_vals mem functionsKeith Packard2017-12-12
| | | | | | Avoids the extra stack depth of the poly versions. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: More compiler warning cleanupsKeith Packard2017-12-12
| | | | | | Make local funcs static. Don't mix decls and code.x Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: apply const to places taking const strings.Keith Packard2017-12-12
| | | | | | Mostly printf and friends. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Support scheme subsetting via feature settingsKeith Packard2017-12-12
| | | | | | | This provides for the creation of smaller versions of the interpreter, leaving out options like floating point numbers and vectors. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Add ao_scheme_vector.cKeith Packard2017-12-12
| | | | | | Useful to include the code for implementing vectors Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Allow ao_scheme_read_eval_print to be restartedKeith Packard2017-12-11
| | | | | | Reset exceptions at the top so that we can call it more than once. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Add Makefile for scheme test appKeith Packard2017-12-11
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Make test scheme app heap maximum sizeKeith Packard2017-12-11
| | | | | | It's only 32kB. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Make eqv? work for numbers and stringsKeith Packard2017-12-11
| | | | | | | Large numbers, floats and strings need a value check, not just a comparison between ao_polys Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Stash cons across value allocation in compareKeith Packard2017-12-11
| | | | | | | Large ints, strings and floats can cause allocation, requiring that the 'cons' pointer be stashed and retrieved in case it moved. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: add list-copyKeith Packard2017-12-11
| | | | | | A lot easier as a built-in; the obvious scheme version is recursive. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Use 64-bit ints to track memory allocation statsKeith Packard2017-12-11
| | | | | | | These are only collected for debug purposes, but can get quite large if the interpreter runs for a while. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Add a bunch of string and vector builtinsKeith Packard2017-12-11
| | | | | | Just make the language closer to r7rs Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Avoid crashing with non-list in lengthKeith Packard2017-12-10
| | | | | | | Use ao_scheme_cons_cdr to fetch the next list element as that returns NULL for non-cons elements. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Add vectorsKeith Packard2017-12-10
| | | | | | Constant time and smaller can be a feature. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Fix name of constant scheme fileKeith Packard2017-12-10
| | | | | | .lisp -> .scheme Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Let readline know if there's a list in progressKeith Packard2017-12-09
| | | | | | | This lets the interactive prompt change based on what state the lexer is in Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/cortexelf-v1: Adapt to lisp->scheme name changeKeith Packard2017-12-05
| | | | Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Add explicit dependency on ao_scheme_builtin.h for ↵Keith Packard2017-12-05
| | | | | | | | | ao_scheme_make_const This ensures that a parallel build will wait for ao_scheme_builtin.h to be complete before attempting to compile ao_scheme_make_const Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/scheme: Move scheme test program to scheme sub-directoryKeith Packard2017-12-05
| | | | | | Keeps it away from the usual test setup Signed-off-by: Keith Packard <keithp@keithp.com>
* 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>
