This version adds the try ... catch statement to catch errors and exceptions. It also streamlines some of the advanced API's.

Version 0.19.3 released to crates.io.

Breaking changes

  • EvalAltResult::ErrorReadingScriptFile is removed in favor of the new EvalAltResult::ErrorSystem.
  • EvalAltResult::ErrorLoopBreak is renamed to EvalAltResult::LoopBreak.
  • Engine::register_raw_fn and FnPtr::call_dynamic function signatures have changed.
  • Callback signatures to Engine::on_var and Engine::register_custom_syntax have changed.
  • EvalAltResult::ErrorRuntime now wraps a Dynamic instead of a string.
  • Default call stack depth for debug builds is reduced to 8 (from 12) because it keeps overflowing the stack in GitHub CI!
  • Keyword thread is reserved.

New features

  • The plugins system is enhanced to support functions taking a NativeCallContext as the first parameter.
  • throw statement can now throw any value instead of just text strings.
  • New try ... catch statement to catch exceptions.

Enhancements

  • Calling eval or Fn in method-call style, which is an error, is now caught during parsing.
  • func!() call style is valid even under no_closure feature.
