      py: Don't automatically intern strings in parser. · 5042bce8
      Damien George authored
      This completes non-automatic interning of strings in the parser, so that
      doc strings don't take up RAM.  It complicates the parser and compiler,
      and bloats stmhal by about 300 bytes.  It's complicated because now
      there are 2 kinds of parse-nodes that can be strings: interned leaves
      and non-interned structs.

      py: Turn down amount of RAM parser and compiler use. · 66e18f04
      Damien George authored
      There are 2 locations in parser, and 1 in compiler, where memory
      allocation is not precise.  In the parser it's the rule stack and result
      stack, in the compiler it's the array for the identifiers in the current
      scope.  All other mallocs are exact (ie they don't allocate more than is
      This patch adds tuning options (MP_ALLOC_*) to mpconfig.h for these 3
      inexact allocations.
      The inexact allocations in the parser should actually be close to
      logarithmic: you need an exponentially larger script (absent pathological
      cases) to use up more room on the rule and result stacks.  As such, the
      default allocation policy for these is now to start with a modest sized
      stack, but grow only in small increments.
      For the identifier arrays in the compiler, these now start out quite
      small (4 entries, since most functions don't have that many ids), and
      grow incrementally by 6 (since if you have more ids than 4, you probably
      have quite a few more, but it wouldn't be exponentially more).
      Partially addresses issue #560.

      Add license header to (almost) all files. · 04b9147e
      Damien George authored
      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: Add simple way of looking up constants in compiler. · 57e99ebc
      Damien George authored
      Working towards trying to support compile-time constants (see discussion
      in issue #227), this patch allows the compiler to look inside arbitrary
      uPy objects at compile time.  The objects to search are given by the
      macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects),
      and the constant folding occures on forms base.attr (both base and attr
      must be id's).
      It works, but it breaks strict CPython compatibility, since the lookup
      will succeed even without importing the namespace.

      py: Start implementing "struct" module. · e9db8404
      Paul Sokolovsky authored
      Only calcsize() and unpack() functions provided so far, for little-endian
      byte order. Format strings don't support repition spec (like "2b3i").
      Unfortunately, dealing with all the various binary type sizes and alignments
      will lead to quite a bloated "binary" helper functions  - if optimizing for
      speed. Need to think if using dynamic parametrized algos makes more sense.

      py: Add "io" module. · 98a627dc
      Paul Sokolovsky authored
      So far just includes "open" function, which should be supplied by a port.
      TODO: Make the module #ifdef'ed.
