Damien George f5172af1c4 py/builtinhelp: Implement help('modules') to list available modules.
This is how CPython does it, and it's very useful to help users discover
the available modules for a given port, especially built-in and frozen
modules.  The function does not list modules that are in the filesystem
because this would require a fair bit of work to do correctly, and is very
port specific (depending on the filesystem).

Damien George 9de91914fb py: Move weak-link map to objmodule.c, and expose module maps as public. 2017-01-22 11:59:29 +11:00
Damien George 9f04dfb568 py: Add builtin help function to core, with default help msg.
This builtin is configured using MICROPY_PY_BUILTINS_HELP, and is disabled
by default.

Paul Sokolovsky e6ab43e2c0 py/objint_longlong: Add stub for mp_obj_int_from_bytes_impl().
To be implemented later.

Paul Sokolovsky bec7bfb29d py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision.
If result guaranteedly fits in a small int, it is handled in objint.c.
Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should
be implemented by individual objint_*.c, similar to
mp_obj_int_to_bytes_impl().

Paul Sokolovsky 1b42f5251f py/mpz: Implement mpz_set_from_bytes() as a foundation for int.from_bytes(). 2017-01-21 20:07:50 +03:00
Damien George e873243aa3 py/objint_mpz: Refactor switch-statement to remove unreachable default. 2017-01-19 23:35:45 +11:00
Damien George 94a587a750 py/formatfloat: Remove unreachable code.
The if-block that this unreachable code is in has a condition "f>=5" so
"fp_isless1(f)" will always fail.

Paul Sokolovsky af90461931 py/binary: mp_binary_get_size: Raise error on unsupported typecodes.
Previouly, we had errors checked in callers, which led to duplicate code
or missing checks in some places.

Damien George d7150b09d7 py/runtime: Refactor default case of switch to remove assert(0). 2017-01-17 17:03:56 +11:00
Damien George 5bea080737 py/objexcept: Replace if-cond and assert(0) with simple assert. 2017-01-17 17:03:16 +11:00
Damien George f51f22dd42 py/emitnative: Remove assert(0)'s or replace with mp_not_implemented. 2017-01-17 17:02:21 +11:00
Damien George 86e942309a py/parse: Refactor code to remove assert(0)'s.
This helps to improve code coverage.  Note that most of the changes in
this patch are just de-denting the cases of the switch statements.

Damien George 239f920299 py/objgenerator: Don't raise RuntimeError if GeneratorExit ignored.
In this case it's allowed to be ignored.
2017-01-17 00:16:56 +11:00
Damien George 681994638b py/objgenerator: When throwing an object, don't make an exc instance.
Arguments to throw() for generators don't need to be exceptions.
2017-01-17 00:14:14 +11:00
Damien George aeb2655073 py/runtime: Fix handling of throw() when resuming generator.
If GeneratorExit is injected as a throw-value then that should lead to
the close() method being called, if it exists.  If close() does not exist
then throw() should not be called, and this patch fixes this.
2017-01-17 00:10:49 +11:00
Damien George 40863fce6f py/runtime: Refactor assert(0) to improve coverage. 2017-01-17 00:09:56 +11:00
Damien George d23834bc96 py/builtinimport: Remove unreachable code and change obj-import comment. 2017-01-16 16:41:43 +11:00
Damien George 63e291de70 py/builtinimport: Raise ValueError for bad relative import, per CPython. 2017-01-16 16:21:04 +11:00
Damien George b528e9a428 py/builtinimport: Fix bug when importing names from frozen packages.
The commit d9047d3c8a introduced a bug
whereby "from a.b import c" stopped working for frozen packages.  This is
because the path was not properly truncated and became "a//b".  Such a
path resolves correctly for a "real" filesystem, but not for a search in
the list of frozen modules.

Damien George 343b4189b0 py/mkrules.mk: Add MPY_CROSS_FLAGS option to pass flags to mpy-cross.
So that ports can pass their own custom options to mpy-cross.

Damien George 3f9c45efd1 py/asmarm: Fix assembler's PASS_EMIT constant name. 2017-01-03 15:40:50 +11:00
Damien George afc5063539 py/unicode: Comment-out unused function unichar_isprint. 2016-12-28 17:50:10 +11:00
Damien George ea6a958393 py/objint: Simplify mp_int_format_size and remove unreachable code.
One never needs to format integers with a base larger than 16 (but code
can be easily extended beyond this value if needed in the future).
2016-12-28 12:46:20 +11:00
Damien George 44bf8e1f2b py/mpprint: Add assertion for, and comment about, valid base values. 2016-12-28 12:45:33 +11:00
Damien George ca7af9a778 py/parsenum: Fix warning for signed/unsigned comparison. 2016-12-28 12:25:00 +11:00
Damien George 2d9440e2d1 py/mpz: Fix assertion in mpz_set_from_str which checks value of base. 2016-12-28 12:04:19 +11:00
Damien George c2dd494bd9 py/parsenum: Simplify and generalise decoding of digit values.
This function should be able to parse integers with any value for the
base, because it is called by int('xxx', base).

Paul Sokolovsky 25f44c19f1 cc3200: Re-add support for UART REPL (MICROPY_STDIO_UART setting).
UART REPL support was lost in os.dupterm() refactorings, etc. As
os.dupterm() is there, implement UART REPL support at the high level -
if MICROPY_STDIO_UART is set, make default boot.py contain os.dupterm()
call for a UART. This means that changing MICROPY_STDIO_UART value will
also require erasing flash on a module to force boot.py re-creation.

Paul Sokolovsky cf96be60dc py/misc.h: Typo fix in comment. 2016-12-27 01:05:30 +03:00
Damien George c305ae3243 py/lexer: Permanently disable the mp_lexer_show_token function.
The lexer is very mature and this debug function is no longer used.  If
it's really needed one can uncomment it and recompile.
2016-12-22 10:49:54 +11:00
Damien George f4aebafe7a py/lexer: Remove unnecessary check for EOF in lexer's next_char func.
This check always fails (ie chr0 is never EOF) because the callers of this
function never call it past the end of the input stream.  And even if they
did it would be harmless because 1) reader.readbyte must continue to
return an EOF char if the stream is exhausted; 2) next_char would just
count the subsequent EOF's as characters worth 1 column.

Damien George b9c4783273 py/lexer: Remove unreachable code in string tokeniser. 2016-12-22 10:37:13 +11:00
Damien George adccafb42a tests/basics/lexer: Add a test for newline-escaping within a string. 2016-12-22 10:32:06 +11:00
Paul Sokolovsky d02f6a9956 extmod/modutimeq: Refactor into optimized class.
import utimeq, utime
    # Max queue size, the queue allocated statically on creation
    q = utimeq.utimeq(10)
    q.push(utime.ticks_ms(), data1, data2)
    res = [0, 0, 0]
    # Items in res are filled up with results
    q.pop(res)

Damien George 46a6592f9a py/emitglue: Refactor to remove assert(0), to improve coverage. 2016-12-21 11:52:05 +11:00
Damien George e4af712125 py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.
And also simplify it to remove the check for small int.  This can be done
because this function is only ever called if the argument is not a small
int.

Damien George 7318949c46 py/modbuiltins: Remove unreachable code. 2016-12-20 14:00:59 +11:00
Damien George de9cd00b39 py/compile: Add an extra pass for Xtensa inline assembler.
It needs an extra pass to compute the size of the constant table for the
l32r instructions.
2016-12-19 17:42:25 +11:00
Damien George 7f1da0a03b py: Add MICROPY_KBD_EXCEPTION config option to provide mp_kbd_exception.
Defining and initialising mp_kbd_exception is boiler-plate code and so the
core runtime can provide it, instead of each port needing to do it
themselves.

The exception object is placed in the VM state rather than on the heap.
2016-12-15 13:00:19 +11:00
Paul Sokolovsky 403c93053e py/mpconfig.h: Enable MICROPY_PY_SYS_EXIT by default.
sys.exit() is an important function to terminate a program. In particular,
the testsuite relies on it to skip tests (i.e. any other functionality may
be disabled, but sys.exit() is required to at least report that properly).
2016-12-14 21:22:05 +03:00
Damien George e8f2db7da3 py/runtime: Zero out fs_user_mount array in mp_init.
There's no need to force ports to copy-and-paste this initialisation
code.  If FSUSERMOUNT is enabled then this zeroing out must be done.
2016-12-14 11:40:11 +11:00
Damien George e83f140463 py/mpz: Remove unreachable code in mpn_or_neg functions. 2016-12-14 10:39:41 +11:00
Damien George d9047d3c8a py/builtinimport: Support importing packages from compiled .mpy files.
This patch ensures that __init__.mpy files are imported if their
containing directory is imported as a package.

Damien George a3c61004c2 py/binary: Do zero extension when storing a value larger than word size. 2016-12-12 15:00:06 +11:00
Paul Sokolovsky 9d787de2a1 py/objint: from_bytes, to_bytes: Require byteorder arg, require "little".
CPython requires byteorder arg, make uPy compatible. As we support only
"little", error out on anything else.

Damien George 93ee6603b1 py/asm: Fix x86 and ARM assemblers due to recent code refactoring. 2016-12-09 22:54:45 +11:00
Damien George 155fdc74d5 py/asm: Remove need for dummy_data when doing initial assembler passes.
For all but the last pass the assembler only needs to count how much space
is needed for the machine code, it doesn't actually need to emit anything.
The dummy_data just uses unnecessary RAM and without it the code is not
any more complex (and code size does not increase for Thumb and Xtensa
archs).
2016-12-09 22:50:58 +11:00
Damien George e920bab976 py/emitinline: Move common code for end of final pass to compiler.
This patch moves some common code from the individual inline assemblers to
the compiler, the code that calls the emit-glue to assign the machine code
to the functions scope.
2016-12-09 21:23:17 +11:00
Damien George dd53b12193 py/emitinline: Move inline-asm align and data methods to compiler.
These are generic methods that don't depend on the architecture and so
can be handled directly by the compiler.
