Paul Sokolovsky e9db840480 py: Start implementing "struct" module.
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.

Damien George b5fbd0ba87 py: Add mp_obj_is_integer; make mp_get_index check for long int.
mp_obj_is_integer should be used to check if an object is of integral
type.  It returns true for bool, small int and long int.

Damien George 88d7bba961 py: Make it so that printing a small int does not allocate heap memory.
With the implementation of proper string formatting, code to print a
small int was delegated to mpz_as_str_inpl (after first converting the
small int to an mpz using stack memory).  But mpz_as_str_inpl allocates
heap memory to do the conversion, so small ints needed heap memory just
to be printed.

This fix has a separate function to print small ints, which does not
allocate heap, and allocates less stack.

String formatting, printf and pfenv are now large beasts, with some
semi-duplicated code.

Paul Sokolovsky a985b4593d objint: Implement int.from_bytes() class method and .to_bytes() method.
These two are apprerently the most concise and efficient way to convert
int to/from bytes in Python. The alternatives are struct and array modules,
but methods using them are more verbose in Python code and less efficient
in memory/cycles.

Display \r and \t escape codes in string repr
2014-04-08 12:11:40 +01:00
Damien George 97790455fe Improve REPL detecting when input needs to continue.
Full CPython compatibility with this requires actually parsing the
input so far collected, and if it fails parsing due to lack of tokens,
then continue collecting input.  It's not worth doing it this way.  Not
having compatibility at this level does not hurt the goals of Micro
Python.

Damien George a12a0f78b0 py: Rename pfenv_print_int to pfenv_print_mp_int, and add back former.
stmhal relies on pfenv_* to implement its printf.  Thus, it needs a
pfenv_print_int which prints a proper 32-bit integer.  With latest
change to pfenv, this function became one that took mp_obj_t, and
extracted the integer value from that object.

To fix temporarily, pfenv_print_int has been renamed to
pfenv_print_mp_int (to indicate it takes a mp_obj_t for the int), and
pfenv_print_int has been added (which takes a normal C int).  Currently,
pfenv_print_int proxies to pfenv_print_mp_int, but this means it looses
the MSB.  Need to find a way to fix this, but the only way I can think
of will duplicate lots of code.
