59a41e8fcd py/qstr: Fix calc of qstr memory usage, due to new qstr chunk allocation. 2015-10-13 15:52:06 +01:00

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.

fdfcee7b1e py/parse: Make parser error handling cleaner, less spaghetti-like. 2015-10-12 12:59:18 +01:00

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.

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').

1b586f3a73 py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming. 2015-10-11 15:18:15 +03:00

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.

366239b8b9 py/parse: Factor logic when creating parse node from and-rule. 2015-10-08 23:13:18 +01:00

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.

7e12a601b8 py/compile: Fix edge case when constant-folding negation of integer. 
Also adds tests specifically for testing constant folding.

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.

2065373f67 py/mpz: Fix bignum anding of large negative with smaller positive int. 2015-10-01 22:35:06 +01:00

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.

4c02e54298 py/mpz: Raise NotImplError instead of failing assertion. 2015-10-01 17:57:36 +01:00

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.

f1a9923308 py/objrange: Bugfix for range_subscr() when index is a slice object. 2015-09-28 14:01:28 +00:00

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.

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).

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

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.

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.

Eg 0e0 almost looks like a hex number but in fact is a float.

42cec5c893 py/objstr: Check for keyword args before checking for no posn args. 
Otherwise something like bytes(abc=123) will succeed.

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.

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.

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.
