Damien George 2077397118 py: Put number parsing code together in parsenum.c. 2014-02-22 18:12:43 +00:00
Paul Sokolovsky 56e5ef203b parse: Refactor parse node encoding to support full range of small ints.
Based on suggestion by @dpgeorge at
https://github.com/micropython/micropython/pull/313

Paul Sokolovsky bbf0e2fe12 parse: Note that fact that parser's small ints are different than VM small int.
Specifically, VM's small ints are 31 bit, while parser's only 28. There's already
MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to
MP_PARSE_FITS_SMALL_INT().

Damien George c5966128c7 Implement proper exception type hierarchy.
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of.  When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).

Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.

Handling of parse error changed to match new exceptions.

mp_const_type renamed to mp_type_type for consistency.

Damien George b829b5caec Implement mp_parse_node_free; print properly repr(string). 2014-01-25 13:51:19 +00:00
Paul Sokolovsky aee2ba70de Add parse_node_free_struct() and use it to free parse tree after compilation.
TODO: Check lexer/parse/compile error path for leaks too.

Damien George cbd2f7482c py: Add module/function/class name to exceptions.
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

Damien George 08335004cf Add source file name and line number to error messages.
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

Damien George 9528cd66d7 Convert parse errors to exceptions.
Parser no longer prints an error, but instead returns an exception ID
and message.

Damien d99b05282d Change object representation from 1 big union to individual structs.
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).
