Unreleased

0.5.0 - 2024-09-19

Changed

The behavior of whether a JavaScript number is converted into Python float or int has changed.
- Before: Numbers that are valid 32-bit signed/unsigned integers (i32/u32) are converted into int. Others are converted into float.
- After: Non-whole numbers are converted into float. Whole-number conversion is controlled by the parameter integer_conversion. The valid values are, in the order of increasing aggressiveness:
  - never: All numbers are converted into float.
  - i32: Only valid 32-bit integers are converted into int. This seems to be the common behavior of other embedded JavaScript engines.
  - safe: Whole numbers within the safe-integer range are converted into int. This is the default.
  - aggressive: Even unsafe integers are converted into int.

0.4.0 - 2024-03-03

Added

JavaScript evaluation raises JsError for uncaught JavaScript exceptions. Evalution includes JsFunction calls, and Runtime methods eval, mod_evaluate, call.
- For function calls, the raised JsError object stores the thrown JavaScript exception in the attribute value.
Runtime.eval() accepts an optional name argument, for better source code location reporting.

0.3.0 - 2024-02-19

Changed

JavaScript values of complex types are no longer converted to Python dict/list by default, but wrapped in JsObject/JsArray objects.
- They can be recursively unwrapped with Runtime.unwrap().
- Methods that return a JavaScript value gain the keyword argument unwrap.

Added

JsFunction objects are now callable directly, without the need to use Runtime.call().
- They can be called as methods, by passing a keyword argument this.
Runtime.get(object, property, unwrap=False).

0.2.0 - 2024-02-02

Fixed

Create at most 1 Runtime per thread, to fix the segfault when too many Runtime objects are created on the stack.

0.1.0 - 2024-01-19

Initial release: module loading, code evaluation, type conversions, function calls.
