suspect-devices/circuitpython/py/parse.c, branch v1.8.5 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.8.5 2016-09-23T07:23:16+00:00 py/parse: Only replace constants that are standalone identifiers. 2016-09-23T07:23:16+00:00 Damien George damien.p.george@gmail.com 2016-09-23T07:23:16+00:00 urn:sha1:6d310a5552f43b3f984a5d8020b41301ab7937a4 This fixes constant substitution so that only standalone identifiers are replaced with their constant value (if they have one). I.e. don't replace NAME in expressions like obj.NAME or NAME = expr. py/parse: Treat constants that start with underscore as private. 2016-06-06T16:28:32+00:00 Damien George damien.p.george@gmail.com 2016-06-06T16:28:32+00:00 urn:sha1:b1533c43669c037d04c87d1756355cdc8edd5e0a Assignments of the form "_id = const(value)" are treated as private (following a similar CPython convention) and code is no longer emitted for the assignment to a global variable. See issue #2111. py: Declare constant data as properly constant. 2016-05-20T11:46:20+00:00 Damien George damien.p.george@gmail.com 2016-05-20T11:38:15+00:00 urn:sha1:3ff16ff52e45d4c0bf1df5fa650b72d6d835451b Otherwise some compilers (eg without optimisation) will put this read-only data in RAM instead of ROM. py/parse: Add uerrno to list of modules to look for constants in. 2016-05-10T22:30:39+00:00 Damien George damien.p.george@gmail.com 2016-05-10T22:23:50+00:00 urn:sha1:e36ff98c80aa93a2f9fdd05800aaa6e75ead2b72 py: Simplify "and" action within parser by making ident-rules explicit. 2016-04-14T12:49:23+00:00 Damien George damien.p.george@gmail.com 2016-04-14T12:23:50+00:00 urn:sha1:0c1de1cdeea98e55710d27f7926da717086ac0fc Most grammar rules can optimise to the identity if they only have a single argument, saving a lot of RAM building the parse tree. Previous to this patch, whether a given grammar rule could be optimised was defined (mostly implicitly) by a complicated set of logic rules. With this patch the definition is always specified explicitly by using "and_ident" in the rule definition in the grammar. This simplifies the logic of the parser, making it a bit smaller and faster. RAM usage in unaffected. py: Fix constant folding and inline-asm to work with new async grammar. 2016-04-13T14:26:39+00:00 Damien George damien.p.george@gmail.com 2016-04-13T14:21:47+00:00 urn:sha1:eacbd7aeba3bdd634b56af544e40da87779f4a95 py/parse: When looking up consts, check they exist before checking type. 2016-03-19T21:36:32+00:00 Damien George damien.p.george@gmail.com 2016-03-19T21:36:32+00:00 urn:sha1:8d4d6731f56f9b1163f19d2455e8998aa0499afd py/parse: Use m_renew_maybe to ensure that memory is shrunk in-place. 2016-02-23T13:44:29+00:00 Damien George damien.p.george@gmail.com 2016-02-23T13:44:29+00:00 urn:sha1:d6c558c0aae53d3cd5f8871394f44bd23836307e The chunks of memory that the parser allocates contain parse nodes and are pointed to from many places, so these chunks cannot be relocated by the memory manager. This patch makes it so that when a chunk is shrunk to fit, it is not relocated. py: unary_op enum type fix, and a cast to remove clang warning 2016-01-12T21:06:39+00:00 Antonin ENFRUN antonin.e@me.com 2016-01-12T21:06:39+00:00 urn:sha1:efc971e8f9b69bbab32d5677239f2dfb16e8f3be py/parse: Include unistd.h for ssize_t definition. 2016-01-08T13:42:00+00:00 Damien George damien.p.george@gmail.com 2016-01-08T13:42:00+00:00 urn:sha1:7dbf74c5b976ae92aab5c941cc777bb0c6a36592 In some cases ssize_t is not defined by already included headers.
