v0.3.0

Highlights since v0.1.17.

New modules

• EPM (Egg Package Manager): config-driven workflows — new, init, start, dev, install, list, test.
• ArgParser: command/option parser with parse-result objects, used by EPM and friends.
• Random: PCG XSH-RR PRNG.
• TOML: parser + writer with tests.
• SUnit: full test framework module, with TestSuite class>>forModule: and TestSuite>>runDebug for log-as-you-go runs.
• Compiler.Tests module (SmalltalkScanner tests, etc.).

Compiler & Bootstrap

• New self-hosted Smalltalk compiler/parser stack: AST nodes, binding classes, environments, semantic visitor.
• BootstrappedKernel and a refactor splitting Bootstrapper into Loader + SymbolProvider.
• Catch2-based C++ tests for the parser, source loader, and compilation.
• MethodDictBuilder abstraction extracted.
• Tonel reader: support Extension types, comments, method category, $-escaped delimiters, block reader fix, sorted methods, class comments, tests.
• LargeInteger encoded as little-endian bytes; parser cleanup.
• Inliner: never inline cascade messages.
• Parse/compile errors enriched with file:line:col context.

VM / Runtime (C++)

• DNU support:
  • VM dispatches DNU through _doesNotUnderstand:with: rather than aborting.
  • Runtime::sendLocal_to_* and Evaluator::messageNotUnderstood_ now intern selectors via addSymbol_ so unknown selectors raise a clean MNU instead of crashing.
  • Top-level try/catch in Main.cpp surfaces runtime errors as Error: ....
• Process / stack model: ProcessVMStack backed by an explicit per-process buffer, with new primitiveProcessVMStackInitializeWith* primitives.
• Ensure / non-local returns: VM ensure support, better closure non-local return unwinding, returnTo underprimitive.
• Primitives added: HostExit, float-from-integer creation, additional float primitives, missing host primitives for the Pharo runtime, filesystem & env primitives, search-path module loading.
• Hardening:
  • SmallInteger arithmetic & bitwise overflow fallback; portable intptr_t mul-overflow helper for MSVC.
  • Float>>timesTwoPower: primitive fixed.
  • StringReplaceFromToWithStartingAt bounds fixed.
  • Integer and at: primitives hardened.
  • commitMemoryUpTo_ length calculation fixed in the allocator.
  • DynamicSymbolProvider symbol table now GC-protected.
  • Fail gracefully on module-load exceptions; warn (not abort) on missing primitive.
  • Skip undermessage registration when the symbol is not yet interned (avoids stale nullptr-keyed dispatch).
  • failPrimitiveWith_ helper.

Kernel

• String class>>new (delegates to new: 0).
• ProtoObject _uLongAtOffset: / _uLongAtValidOffset:put:.
• WideSymbol class>>intern: operates on the argument.
• ProtoObject>>doesNotUnderstand: passes the receiver into MessageNotUnderstood.
• ReadStream peek methods refactored.
• Property tables fixed.
• MessageNotUnderstood class>>printOn: added.
• ensure support fixes.
• Float>>= only consults FPU status when the argument is also a Float.

Module loader

• Relative module search paths; throw on missing module.
• Dotted module names and load-from-path supported.

Build & infra

• Build system migrated to a conanfile.py; dropped -s compiler.cppstd=20 workaround.
• Default Debug builds now use -O1 for usable VM speed.
• egg_runtime library extracted; bootstrapper_lib linked into compiler_tests; declared egg_runtime ↔ bootstrapper_lib cycle.
• Build dirs and settings.json ignored.
• STONWriter initialized on module load.

Documentation

• Updated README with building table and C++ platform status.
• Expanded contributor docs (style guides + runtime READMEs).
• Coding style extracted into CODING_STYLE.md.
• Git commit labelling format documented.

Tests

• New regression tests: test182BitShiftRightFullWidth, additional bitwise/shift tests with a runnable main:.
