LOW_MEM drops some functionality (like `defe`) for very low memory devices like
aplite. SIMPLE_ERRORS is enabled when compiling with LOW_MEM, and overrides the
new error-with-context functionality with older, less intensive methods.
Also marked more code for standalone compilation only.
External:
Error changes.
User windows will show string reps of all object types
Internal:
Some re-org and renames in calc.
Add stringNObj for more controlled string-receiving.
Note: currently aplite has a hard time with larger scripts, possibly because of
recent changes. Not sure how much can be done about it, but I'm investigating.
`iserr` is a basic type-check like `isnum`
`defe` adds a string to the environment as the equivalent symbol
`eval` can take in variables or functions, instead of just raw strings
Broke type-printing into its own function
Errors maxing out an environment. Likely extending incorrectly
Move most file-local variables from calc.h to calc.c (so calc.h can be included)
Quick hack to get simple TYPE_LAMBDA evaluated
Add pebcom files for time/vibe/eventually battery etc. functions
Add TYPE_OTHER, so that pebble-specific (and potentially other) objects can be used in PebbLisp
Created PebbleObject/PebbleType to work as a sort of tagged pointer, to be used as a TYPE_OTHER object
Add some functions for creating/editing windows and textlayers from within PebbLisp
Added subscribe(), enabling lambdas to be run at set time intervals
