The Express builds have >40k free in flash. I've added several minor Python features that were turned off, but are small and convenient. I also turned on one major extra: the
uremodule, which is very useful for reducing the size of ad hoc parsing code.Bytes used for each addition (measured in 0.9.7 builds):
47588 bytes free in flash
MICROPY_PY_BUILTINS_STR_CENTER: 120 bytesMICROPY_PY_BUILTINS_STR_PARTITION: 264 bytesMICROPY_PY_BUILTINS_STR_FROZENSET: 272 bytesMICROPY_PY_BUILTINS_STR_SPLITLINES: 200 bytesMICROPY_PY_BUILTINS_REVERSED: 176 bytesMICROPY_PY_URE: 2944 bytestotal 4096
before additions: 47588 bytes free
after: 43592 bytes free
A couple of notes:
frozensetis actually slightly broken: the sets aren't immutable (fixed in a later version of micropython).ujson, but there were errors building due to some #defines invfs_fat_file.h(here) that cause undefined symbols. This is also fixed in a later version of micropython: the vfs code was refactored significantly.
