Share & Enjoy!
PS: We could use a little more sophisticated Makefile system....
--------------------------------------------------------------------------
Changes in topaz 0.11:
* Organize code into subdirectories:
mem Memory management etc.
val Value and derivations
op Opcodes etc.
int Interpreter etc.
tools scripts
* Rename all FooPtr -> Foo_p, ConstFooPtr -> const_Foo_p.
* Create Counted_p_ref<> by analogy with auto_ptr_ref<>, designed
for return-by-value. Its contained pointer is always stolen.
The intent is to reduce ref thrashing.
* Likewise Buffer_ref vs. Buffer.
* New stuff in mem:
HashMisc: misc support for hash functions
HashTable: low-level hash table support
HashSet: generic container based on HashTable<>
* Defined/undefined isn't really a universal concept, so it's no
longer part of the Value interface.
* Rationalize array/hash interface. All methods must be specific
to arrays or hashes; otherwise, we can't tell if a reference is
of appropriate type or not.
* Hashes no longer contain default iterators. This change will
will require a bit of language support, but Larry sez it'll
probably work, and that's good enough for me.
* FatHash is now implemented with our own HashSet<> template
instead of the more general (and higher-overhead) map<>.
* New class: Stash, a specialized container of Globs that acts
like a Hash when it has to. (Also: GlobProxyScalar.)
* Interpreter's methods are now mostly friends, for convenience.
* Code class is now general for all functions, user-defined or
not. (Otherwise, you can't redefine a user sub with an XSUB or
vice versa.) All user-sub-specific intelligence is in
UserCodeBody, derived from the new abstract base Code::Body.
