* py: Move global/nonlocal decl code to compiler for proper SyntaxError.Damien George2014-12-21
| | | | | | This patch gives proper SyntaxError exceptions for bad global/nonlocal declarations. It also reduces code size: 304 bytes on unix x64, 132 bytes on stmhal.
* py: Convert [u]int to mp_[u]int_t in emit.h and associated .c files.Damien George2014-09-08
| | | | Towards resolving issue #50.
* py: Change uint to mp_uint_t in runtime.h, stackctrl.h, binary.h.Damien George2014-08-30
| | | | Part of code cleanup, working towards resolving issue #50.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. 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/.
* py: Implement keyword-only args.Damien George2014-04-27
| | | | | | | Implements 'def f(*, a)' and 'def f(*a, b)', but not default keyword-only args, eg 'def f(*, a=1)'. Partially addresses issue #524.
* py: Remove unique_codes from emitglue.c. Replace with pointers.Damien George2014-04-13
| | | | | | | | | | | | | | | | Attempt to address issue #386. unique_code_id's have been removed and replaced with a pointer to the "raw code" information. This pointer is stored in the actual byte code (aligned, so the GC can trace it), so that raw code (ie byte code, native code and inline assembler) is kept only for as long as it is needed. In memory it's now like a tree: the outer module's byte code points directly to its children's raw code. So when the outer code gets freed, if there are no remaining functions that need the raw code, then the children's code gets freed as well. This is pretty much like CPython does it, except that CPython stores indexes in the byte code rather than machine pointers. These indices index the per-function constant table in order to find the relevant code.
* py: Properly implement deletion of locals and derefs, and detect errors.Damien George2014-04-09
| | | | | Needed to reinstate 2 delete opcodes, to specifically check that a local is not deleted twice.
* py, compiler: Turn id_info_t.param into a set of flags.Damien George2014-04-09
| | | | So we can add more flags.
* py, compiler: Clean up and compress scope/compile structures.Damien George2014-04-09
| | | | | Convert int types to uint where sensible, and then to uint8_t or uint16_t where possible to reduce RAM usage.
* py: Calculate maximum exception stack size in compiler.Damien George2014-03-27
|
* py: Pass all scope flags through to runtime.Damien George2014-02-15
|
* mp_compile(): Properly free module_scope and all nested scopes.Paul Sokolovsky2014-01-23
|
* py: Add module/function/class name to exceptions.Damien George2014-01-19
| | | | | | | Exceptions know source file, line and block name. Also tidy up some debug printing functions and provide a global flag to enable/disable them.
* py: make closures work.Damien George2013-12-30
|
* Change object representation from 1 big union to individual structs.Damien2013-12-21
| | | | | | | | | | A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
* py: work towards working closures.Damien2013-12-11
|
* Add local_num skeleton framework to deref/closure emit calls.Damien2013-10-20
|
* Implement built-in decorators to select emit type.Damien2013-10-05
|
* Further factorise PASS_1 out of specific emit code.Damien2013-10-05
|
* Restructure emit so it goes through a method table.Damien2013-10-05
|
* Initial commit.Damien2013-10-04
