Tested on a pyboard. Code size is 77592 bytes. 2015-11-09T13:13:09+00:00 Damien George damien.p.george@gmail.com 2015-11-09T13:13:09+00:00 urn:sha1:40274fec9c0f8e1ce06f999927f550106b9aa5e8 2015-10-01T23:11:11+00:00 Damien George damien.p.george@gmail.com 2015-09-23T09:50:43+00:00 urn:sha1:58e0f4ac50b3dc732cbfe0d7b04bb41951ac1329 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. 2015-06-22T21:38:47+00:00 Damien George damien.p.george@gmail.com 2015-06-22T21:38:47+00:00 urn:sha1:c4b592d3793bae6effe13a9b606083c9097d2779 The do_str() function is provided essentially as documentation to show how to compile and execute a string. This patch makes do_str take an extra arg to specify how the string should be interpreted: either as a single line (ie from a REPL) or as multiple lines (ie from a file). 2015-05-05T23:02:58+00:00 Damien George damien.p.george@gmail.com 2015-05-05T23:02:58+00:00 urn:sha1:c98c128fe885e539ecd73843756340f8950115c8 esp8266 port now has working raw and friendly REPL, as well as working soft reset (CTRL-D at REPL, or raise SystemExit). tools/pyboard.py now works with esp8266 port. 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. 2015-02-13T15:26:53+00:00 Damien George damien.p.george@gmail.com 2015-02-13T15:26:53+00:00 urn:sha1:601c814603801ad3af78e37d26c87a4470156738 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. 2015-01-15T23:53:33+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-01-15T23:53:33+00:00 urn:sha1:2276eb808499b81f7c6e32ab1d497afa020c9379 2015-01-15T23:38:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-01-15T23:38:10+00:00 urn:sha1:d7337f288e9411d8473c6c77aa35a00b50346ca7
