Consolidate all Obj* type forward declarations from wren_value.h into wren_common.h
to centralize type definitions and reduce header dependencies. Convert anonymous
typedef structs to named structs with sObj* tags for consistent naming convention
across all object types.
Add parentheses around the `count` parameter in both `ALLOCATE_FLEX` and
`ALLOCATE_ARRAY` macro definitions to prevent operator precedence bugs when
the argument is an expression. Without this fix, expressions like
`sizeof(type) * n + 1` would be evaluated incorrectly due to `*` having
higher precedence than `+`.
Rename the `src/aux/` directory to `src/optional/`, update all include guards, preprocessor defines, and file references from `WREN_AUX_*` to `WREN_OPT_*`, and adjust build system, Xcode project, and code generation scripts accordingly.
Restructure module hierarchy by extracting meta and random from the core VM and CLI-specific modules into a new "aux" (auxiliary) directory. This introduces WREN_AUX_META and WREN_AUX_RANDOM configuration flags, updates include paths and build system to compile aux sources separately, removes random module registration from CLI modules.c, and adjusts the VM's module loading to implicitly import core into all modules regardless of name.
Add fallback empty UNREACHABLE() definition for GCC < 4.5 and non-MSVC compilers, and insert return/break statements after all UNREACHABLE() calls to prevent -Wreturn-type warnings when the macro expands to nothing. Also cast malloc result to char* in io.c to suppress C++ compilation warning.
- Delete wren_io.c, wren_io.h, and io.wren source files
- Remove multi-arity print overloads and IO.read/IO.time methods
- Add System class with print, printAll, write, writeAll methods to core.wren
- Update all documentation examples and README to use System.print instead of IO.print
Rename the constructor initializer signature prefix from "this " to "init " in
wren_common.h's MAX_METHOD_SIGNATURE calculation, wren_compiler.c's
signatureToString and createDefaultConstructor functions, and wren_core.c's
default Object constructor primitive registration. This changes the syntactic
keyword used to define initializer methods in the Wren language.
- Switch Travis CI from sudo-based apt-get to addons.apt.packages for gcc-multilib
- Enable container-based builds with `sudo: false`
- Update README.md call-to-action links to point to getting-started and browser playground
- Replace `printList_` with `printAll` in IO class and remove redundant `IO.` prefixes
- Add IO.read() method documentation and update IO.print docs for up to 16 arguments
- Reorganize community page with Libraries, Language bindings, and Tools sections
- Add wrenjs JavaScript binding and Sublime Text syntax highlighting
- Fix typo "no where" to "nowhere" in fibers documentation
- Add indentation to preprocessor defines in wren_common.h for consistency
- Remove unreachable `return 0` after UNREACHABLE() in wren_compiler.c
- Fix Windows color output by wrapping text in str() in test script
Replace all uses of the `new` reserved word with explicit `this new()` constructor definitions and `ClassName.new()` instantiation calls in builtin/core.wren. Update all documentation files (classes.markdown, fiber.markdown, fn.markdown, sequence.markdown, error-handling.markdown, expressions.markdown, fibers.markdown, functions.markdown) to reflect the new constructor syntax, removing `new` keyword examples and replacing them with `ClassName.new()` patterns and `this new()` definitions.
Separate Wren VM library sources from CLI tool sources by moving them into
src/vm/ and src/cli/ subdirectories respectively. Update the Makefile to use
separate wildcard patterns for each directory, generate distinct object file
paths under build/vm/ and build/cli/, and adjust include paths to src/include.
Also update the Xcode project file to reference the new file locations.
