CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=encoding 2015-08-17T11:51:26+00:00 2015-08-17T11:51:26+00:00 Damien George damien.p.george@gmail.com 2015-08-14T11:24:11+00:00 urn:sha1:65dc960e3b22a8426e369607e47c19b380ce30ea unix-cpy was originally written to get semantic equivalent with CPython without writing functional tests. When writing the initial implementation of uPy it was a long way between lexer and functional tests, so the half-way test was to make sure that the bytecode was correct. The idea was that if the uPy bytecode matched CPython 1-1 then uPy would be proper Python if the bytecodes acted correctly. And having matching bytecode meant that it was less likely to miss some deep subtlety in the Python semantics that would require an architectural change later on. But that is all history and it no longer makes sense to retain the ability to output CPython bytecode, because: 1. It outputs CPython 3.3 compatible bytecode. CPython's bytecode changes from version to version, and seems to have changed quite a bit in 3.5. There's no point in changing the bytecode output to match CPython anymore. 2. uPy and CPy do different optimisations to the bytecode which makes it harder to match. 3. The bytecode tests are not run. They were never part of Travis and are not run locally anymore. 4. The EMIT_CPYTHON option needs a lot of extra source code which adds heaps of noise, especially in compile.c. 5. Now that there is an extensive test suite (which tests functionality) there is no need to match the bytecode. Some very subtle behaviour is tested with the test suite and passing these tests is a much better way to stay Python-language compliant, rather than trying to match CPy bytecode. 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. 2014-11-16T22:16:14+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-11-16T22:16:14+00:00 urn:sha1:91386eee2613cbaf736d746cfef28674cce82c01 2014-07-03T12:25:24+00:00 Damien George damien.p.george@gmail.com 2014-07-03T12:25:24+00:00 urn:sha1:40f3c026823f8951a2fa04e9c7fc93c75bc27bec See discussion in issue #50. 2014-06-08T12:25:33+00:00 Damien George damien.p.george@gmail.com 2014-06-08T12:25:33+00:00 urn:sha1:4480cb37118b662cf301953595b37704dc197d40 2014-05-24T22:03:12+00:00 Damien George damien.p.george@gmail.com 2014-05-24T22:03:12+00:00 urn:sha1:ee3fd46f1383e984c968c4a82d634d7b0cea49b8 Now of the form MICROPY_PY_*.

Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. 2014-04-13T12:19:28+00:00 Damien George damien.p.george@gmail.com 2014-04-13T12:19:28+00:00 urn:sha1:674f9887ce54b0627758f2a84c52e8aab0d7f2db 2014-04-03T19:08:57+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-04-03T11:57:53+00:00 urn:sha1:98a627dc03bc02e1b827ead8cc71b02259731551 So far just includes "open" function, which should be supplied by a port.
