Consolidate temporary variable usage in list_add, list_count, and list_iterate by directly inlining AS_LIST/AS_NUM calls. Remove the entire block of num_abs, num_acos, num_asin, num_atan, num_atan2, num_ceil, num_cos, num_floor, and num_fraction primitive definitions to eliminate boilerplate.
Add acos, asin, atan, atan2, tan methods to Num class and expose Num.pi constant with value π. Include corresponding C primitives in wren_core.c and test files for each new method.
Convert `validateIndexValue` and `validateIndex` return types to `uint32_t` with `UINT32_MAX` sentinel, update `wrenNewList`, `wrenListInsert`, `wrenListRemoveAt` signatures, and remove the TODO comment about type unification with `ObjMap`.
The contains method is promoted from List to the Sequence base class, making it available to all sequence types (including Range). Tests are added for both List.contains and Range.contains, covering ordered, backwards, and exclusive ranges.
Cache the FNV-1a hash code in the ObjString struct at creation time, replacing the
on-the-fly sampling hash in hashObject() and enabling constant-time string equality
checks. Refactor string allocation into allocateString() and hashString() helpers,
remove the old wrenNewUninitializedString() declaration, and add a CONST_STRING
macro. Disable the unimplemented subscript range operator with a runtime error and
skip the related UTF-8 tests. Add a string_equals benchmark to measure the speedup.
The `List.insert` method signature is changed from `insert(item, index)` to `insert(index, item)`, aligning with standard practice in most languages. All documentation, core implementation, and test files are updated to reflect the new parameter order. The `validateIndex` call now reads the index from slot 1 instead of slot 2, and the value is read from slot 2.
The two validation functions in wren_core.c were calling wrenStringFormat with a format
string containing a "$" placeholder but were not passing the argName argument, causing
the placeholder to remain unsubstituted in error messages. This commit adds the missing
argName parameter to both calls.
Additionally, the CONST_STRING macro in wren_value.h was changed from using strlen(text)
to sizeof(text) - 1, which allows the compiler to compute the string length at compile
time rather than at runtime, improving performance for string literal creation.
Replace ad-hoc string construction using wrenNewString, wrenStringConcat, and sprintf with the new wrenStringFormat helper. This centralizes string formatting logic, reduces code duplication, and eliminates manual length calculations in wren_compiler.c, wren_core.c, wren_value.c, and wren_vm.c. Also introduces CONST_STRING macro for compile-time string literals and changes wrenNewUninitializedString return type from Value to ObjString* for consistency.
The previous signature `insert(element, index)` was counter-intuitive and inconsistent with every major language's list API. This commit swaps the parameters to `insert(index, element)`, matching the convention used by Ruby, JavaScript, C++, Lua, C#, Java, and Python. All documentation, C implementation, and test files are updated to reflect the new order.
Adds a new `atan(_)` primitive method to the Num class that wraps the C
`atan2` function, allowing callers to compute the arc tangent of the
number divided by a given argument `x` while using the signs of both
numbers to determine the correct quadrant of the result. The
implementation registers the primitive `num_atan2` in the core VM
initialization and documents the new method in the core library
reference.
Add a generic `contains` implementation on the `Sequence` base class, removing the duplicate method from `List`. This allows all sequence types (including Range) to use the method without per-class redefinition. Include new test files for `List.contains` and `Range.contains` covering ordered, backwards, and exclusive ranges.
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.
Add the missing `tan` method to the Num class, implementing the tangent
trigonometric function. This fills the gap between the existing `sin` and
`cos` methods, providing a complete set of basic trigonometric operations.
- Register `num_tan` primitive in the VM core initialization
- Implement `DEF_PRIMITIVE(num_tan)` using C's `tan()` math function
- Add documentation entry for `tan` in the core library reference
Change the `capacity` and `count` fields in `ObjList` from `int` to `uint32_t` to match the
types used in `ObjMap`, ensuring consistency between the two structures. Update all loop
variables and index calculations in `wren_core.c` and `wren_value.c` that interact with
these fields to use `uint32_t` instead of `int`, and remove the now-unnecessary negative
bounds check in `list_iterate` since unsigned types cannot be negative.
