suspect-devices/circuitpython/py/lexer.c, branch crossCircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=cross2016-05-20T11:46:20+00:00py: Declare constant data as properly constant.2016-05-20T11:46:20+00:00Damien Georgedamien.p.george@gmail.com2016-05-20T11:38:15+00:00urn:sha1:3ff16ff52e45d4c0bf1df5fa650b72d6d835451b
Otherwise some compilers (eg without optimisation) will put this read-only
data in RAM instead of ROM.
py: add async/await/async for/async with syntax2016-04-13T14:26:38+00:00pohmeliemultisosnooley@gmail.com2016-01-27T20:23:11+00:00urn:sha1:81ebba7e0236163b7594938201bf3a6b802ebfaa
They are sugar for marking function as generator, "yield from"
and pep492 python "semantically equivalents" respectively.
@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.
py: Add MICROPY_DYNAMIC_COMPILER option to config compiler at runtime.2016-02-25T10:05:46+00:00Damien Georgedamien.p.george@gmail.com2016-02-11T22:30:53+00:00urn:sha1:ea23520403777f9b026f49245d39f8be1ccdbdac
This new compile-time option allows to make the bytecode compiler
configurable at runtime by setting the fields in the mp_dynamic_compiler
structure. By using this feature, the compiler can generate bytecode
that targets any MicroPython runtime/VM, regardless of the host and
target compile-time settings.
Options so far that fall under this dynamic setting are:
- maximum number of bits that a small int can hold;
- whether caching of lookups is used in the bytecode;
- whether to use unicode strings or not (lexer behaviour differs, and
therefore generated string constants differ).
py: Add MICROPY_ENABLE_COMPILER and MICROPY_PY_BUILTINS_EVAL_EXEC opts.2015-12-18T12:35:44+00:00Damien Georgedamien.p.george@gmail.com2015-12-18T12:35:44+00:00urn:sha1:dd5353a4054024a411aa343a22ffcd16195a16ad
MICROPY_ENABLE_COMPILER can be used to enable/disable the entire compiler,
which is useful when only loading of pre-compiled bytecode is supported.
It is enabled by default.
MICROPY_PY_BUILTINS_EVAL_EXEC controls support of eval and exec builtin
functions. By default they are only included if MICROPY_ENABLE_COMPILER
is enabled.
Disabling both options saves about 40k of code size on 32-bit x86.
py/lexer: Properly classify floats that look like hex numbers.2015-09-07T16:33:44+00:00Damien Georgedamien.p.george@gmail.com2015-09-07T16:33:44+00:00urn:sha1:2b000474d9350ede1c1aedb83ba8976d81ba4cf8
Eg 0e0 almost looks like a hex number but in fact is a float.

Addresses issue #1390.
py: Cast argument for printf to int, to be compatible with more ports.2015-06-22T16:40:12+00:00Damien Georgedamien.p.george@gmail.com2015-06-22T16:40:12+00:00urn:sha1:7f19a39a3b79f552f158020f33c693913b884e7c
This allows stmhal to be compiled with MICROPY_DEBUG_PRINTERS.
py: Support unicode (utf-8 encoded) identifiers in Python source.2015-06-09T10:58:07+00:00Damien Georgedamien.p.george@gmail.com2015-06-09T10:58:07+00:00urn:sha1:7ed58cb66379f4d87e3e8fbb68baada19048ac18
Enabled simply by making the identifier lexing code 8-bit clean.
