CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.4.3 2015-04-16T14:30:16+00:00 2015-04-16T14:30:16+00:00 Damien George damien.p.george@gmail.com 2015-04-09T22:56:15+00:00 urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs. 2015-03-14T13:11:35+00:00 Damien George damien.p.george@gmail.com 2015-03-14T13:11:35+00:00 urn:sha1:42e0c593084784cb0b630d99b8361bc88abadb78 These allow to fine-tune the compiler to select whether it optimises tuple assignments of the form a, b = c, d and a, b, c = d, e, f. Sensible defaults are provided. 2015-02-07T18:50:54+00:00 Damien George damien.p.george@gmail.com 2015-02-07T18:50:54+00:00 urn:sha1:b5a790d2e690c567ff046f286fe99889ad0e6bec 2015-02-07T18:33:58+00:00 Damien George damien.p.george@gmail.com 2015-02-07T18:33:58+00:00 urn:sha1:0bfc7638baa4c5a4a2351364ab770a188dcab302 To enable parsing constants more efficiently, mp_parse should be allowed to raise an exception, and mp_compile can already raise a MemoryError. So these functions need to be protected by an nlr push/pop block. This patch adds that feature in all places. This allows to simplify how mp_parse and mp_compile are called: they now raise an exception if they have an error and so explicit checking is not needed anymore. 2015-01-01T20:41:52+00:00 Damien George damien.p.george@gmail.com 2015-01-01T20:41:52+00:00 urn:sha1:b36be5ff5172c97a8f37228c1ec163df466fd588 2015-01-01T20:32:09+00:00 Damien George damien.p.george@gmail.com 2015-01-01T20:27:54+00:00 urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde Addresses issue #1022. 2014-12-27T14:32:52+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-27T14:11:49+00:00 urn:sha1:3b74c91684e6dfc785bf33ba03e520470f59059e 2014-12-08T20:25:49+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-06T12:29:09+00:00 urn:sha1:46c3ab20049af16e97863e90e5761fae329f872a The function is modeled after traceback.print_exception(), but unbloated, and put into existing module to save overhead on adding another module. Compliant traceback.print_exception() is intended to be implemented in micropython-lib in terms of sys.print_exception(). This change required refactoring mp_obj_print_exception() to take pfenv_t interface arguments.
