Paul Sokolovsky 7799410950 py/stream: Allow to reuse is_nonblocking_error(). 2015-10-18 15:39:33 +03:00
Damien George 035a0a2b6e py: Add support for _ in REPL to hold last computed value.
Only available when MICROPY_CAN_OVERRIDE_BUILTINS is enabled.

Damien George e813541e3f py: Add option for inline assembler to support ARMv7-M instructions.
Cortex-M0, M0+ and M1 only have ARMv6-M Thumb/Thumb2 instructions.  M3,
M4 and M7 have a superset of these, named ARMv7-M.  This patch adds a
config option to enable support of the superset of instructions.

Damien George 4bf3f2d3c0 py: Fix with+for+return bug by popping for-iter when unwinding exc stack.
Addresses issue #1182.

Damien George 4300c7dba2 py: Remove dependency on printf/fwrite in mp_plat_print.
See issue #1500.

Damien George d7e3b36a09 py/compile: Remove unnecessary label in compilation of for statement. 2015-10-14 15:51:12 +01:00
Damien George fcce1483fa py: Fix build of ARM native emitter due to recent viper changes.
Addresses #1510.

Damien George 59a41e8fcd py/qstr: Fix calc of qstr memory usage, due to new qstr chunk allocation. 2015-10-13 15:52:06 +01:00
Damien George b8f9ac5411 py: Implement ptr32 load and store in viper emitter. 2015-10-13 00:50:17 +01:00
Damien George 3c9c3687d6 py: Add support to call __init__ from a builtin module on first import. 2015-10-12 13:46:01 +01:00
Paul Sokolovsky 408b74d74c py: Allow to to build MicroPython as a static library.
The whole current port gets slurped into a static lib named
"libmicropython.a". Maybe that's not ideal, but at least something
to start with.

Damien George fdfcee7b1e py/parse: Make parser error handling cleaner, less spaghetti-like. 2015-10-12 12:59:18 +01:00
Damien George 64f2b213bb py: Move constant folding from compiler to parser.
It makes much more sense to do constant folding in the parser while the
parse tree is being built.  This eliminates the need to create parse
nodes that will just be folded away.  The code is slightly simpler and a
bit smaller as well.

Constant folding now has a configuration option,
MICROPY_COMP_CONST_FOLDING, which is enabled by default.

Paul Sokolovsky 91fc075a33 py/objarray: Allow to create array of void pointers, as extension to CPython.
Using 'P' format specifier (matches struct module). This is another shortcut
for FFI, just as previously introduced "array of objects" ('O').

Paul Sokolovsky 1b586f3a73 py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming. 2015-10-11 15:18:15 +03:00
Paul Sokolovsky 53ca6ae1f3 py/makeqstrdata.py: Catch and report case of empty input file.
The usual cause would be that a cross-compiler for a port is not in PATH.
2015-10-11 11:09:57 +03:00
Damien George 366239b8b9 py/parse: Factor logic when creating parse node from and-rule. 2015-10-08 23:13:18 +01:00
Damien George b948de36fb py: Don't generate unnecessary parse nodes for assignment or kwargs.
This patch eliminates the need for a nested parse node for assignments
and keyword arguments.  It saves a little bit of RAM when parsing.
2015-10-08 14:26:01 +01:00
Damien George 9f5f156b9d py/emitnative: Raise ViperTypeError for unsupported unary ops. 2015-10-08 13:08:59 +01:00
Damien George 7e12a601b8 py/compile: Fix edge case when constant-folding negation of integer.
Also adds tests specifically for testing constant folding.

Paul Sokolovsky aaa8867d4a modussl: SSL socket wrapper module based on axTLS. 2015-10-06 18:10:39 +03:00
Damien George 0496de26d3 py: Allow to enable inline assembler without native emitter. 2015-10-03 17:07:54 +01:00
Damien George 58e0f4ac50 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.
With this patch parse nodes are allocated sequentially in chunks.  This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.

Saves roughly 20% of RAM during parse stage.

Damien George e5635f4ab3 py: Catch all cases of integer (big and small) division by zero. 2015-10-01 22:48:48 +01:00
Damien George 2065373f67 py/mpz: Fix bignum anding of large negative with smaller positive int. 2015-10-01 22:35:06 +01:00
Damien George 2f4e8511cd py/mpz: Force rhs of mpz_shl_inpl/mpz_shr_inpl to be unsigned.
Python semantics are that rhs of shift must be non-negative, so there's
no need to handle negative values in the underlying mpz implementation.
2015-10-01 18:01:37 +01:00
Damien George 4c02e54298 py/mpz: Raise NotImplError instead of failing assertion. 2015-10-01 17:57:36 +01:00
Damien George 5f3c3ec5e6 py/parsenum: Provide detailed error for int parsing with escaped bytes.
This patch adds more fine grained error message control for errors when
parsing integers (now has terse, normal and detailed).  When detailed is
enabled, the error now escapes bytes when printing them so they can be
more easily seen.

Tom Soulanille f1a9923308 py/objrange: Bugfix for range_subscr() when index is a slice object. 2015-09-28 14:01:28 +00:00
Damien George 9d5e5c08ab py/compile: Put compiler state on the C stack.
It's relatively small (between 44 and 56 bytes) and helps to reduce heap
pressure and fragmentation during compilation.
2015-09-24 13:15:57 +01:00
Damien George fbcaf0ea18 py: Slightly simplify compile and emit of star/double-star arguments.
Saves a few bytes of code space and eliminates need for rot_two
bytecode (hence saving RAM and execution time, by a tiny bit).

Delio Brignoli e6978a4e26 py: Fix call args when a stararg is followed by keyword args. 2015-09-23 11:37:00 +01:00
Alex March bfb272b9e0 py/repl: Treat escaped quotes correctly in REPL continuation.
Escaped quotes are now recognised correctly in REPL when used
inside normal quotes.

Fixes: #1419

Tom Soulanille 661d9d1901 py/objslice: Fix indent. 2015-09-15 22:46:30 +01:00
Tom Soulanille aeb62f9ae3 py/objslice: Make slice attributes (start/stop/step) readable.
Configurable with MICROPY_PY_BUILTINS_SLICE_ATTRS.  Disabled by default.
2015-09-15 21:59:20 +01:00
Damien George 8b4fb4fe14 py/mpz: Fix calculation of max digit storage for mpz; fix sys.maxsize.
When creating constant mpz's, the length of the mpz must be exactly how
many digits are used (not allocated) otherwise these numbers are not
compatible with dynamically allocated numbers.

Addresses issue #1448.
2015-09-15 16:15:57 +01:00
Damien George 0af73014cc lib/mp-readline: Add auto-indent support.
4 spaces are added at start of line to match previous indent, and if
previous line ended in colon.

Backspace deletes 4 space if only spaces begin a line.

Configurable via MICROPY_REPL_AUTO_INDENT.  Disabled by default.

Dave Hylands 9d6128acdc stmhal: fix single precision float printing error
Fixes #1435.
2015-09-11 23:09:50 +03:00
Damien George 2b000474d9 py/lexer: Properly classify floats that look like hex numbers.
Eg 0e0 almost looks like a hex number but in fact is a float.

Damien George 0be3c70cd8 py/lexer: Raise SyntaxError when unicode char point out of range. 2015-09-07 17:19:17 +01:00
Damien George 081f9325f5 py/lexer: Raise NotImplError for unicode name escape, instead of assert. 2015-09-07 17:08:49 +01:00

Damien George 42cec5c893 py/objstr: Check for keyword args before checking for no posn args.
Otherwise something like bytes(abc=123) will succeed.
2015-09-04 16:51:55 +01:00
Damien George 55b11e6d38 py/objstr: For str.endswith(s, start) raise NotImpl instead of assert. 2015-09-04 16:49:56 +01:00
Damien George 0b7a66ab97 py/objbool: Simplify dispatch of bool binary op.
This optimises (in speed and code size) for the common case where the
binary op for the bool object is supported.  Unsupported binary ops
still behave the same.
2015-09-04 16:46:15 +01:00
Damien George ea5b59bfe6 py/compile: Only compile function annotations if really needed.
Function annotations are only needed when the native emitter is enabled
and when the current scope is emitted in viper mode.  All other times
the annotations can be skipped completely.

Tony Abboud 8d8fdcb4be stmhal: add option to query for the current usb mode
Fetch the current usb mode and return a string representation when
pyb.usb_mode() is called with no args. The possible string values are interned
as qstr's. None will be returned if an incorrect mode is set.
