This version basically cleans up the code structure in preparation for a potential 1.0 release in the future.
Most scripts should see a material speed increase.

This version also adds a low-level API for more flexibility when defining custom syntax.

Version 0.19.4 released to crates.io.

Bug fixes

  • Fixes Send + Sync for EvalAltResult under the sync feature. Bug introduced with 0.19.3.

Breaking changes

  • Custom syntax can no longer start with a keyword (even a reserved one), even if it has been disabled. That is to avoid breaking scripts later when the keyword is no longer disabled.

Changes to Error Handling

  • EvalAltResult::ErrorAssignmentToUnknownLHS is moved to ParseError::AssignmentToInvalidLHS. ParseError::AssignmentToCopy is removed.
  • EvalAltResult::ErrorDataTooLarge is simplified.
  • Engine::on_progress closure signature now returns Option<Dynamic> with the termination value passed on to EvalAltResult::ErrorTerminated.
  • ParseErrorType::BadInput now wraps a LexError instead of a text string.

New features

  • f32_float feature to set FLOAT to f32.
  • Low-level API for custom syntax allowing more flexibility in designing the syntax.
  • Module::fill_with to poly-fill a module with another.
  • Scripts terminated via Engine::on_progress can now pass on a value as a termination token.

Enhancements

  • Essential AST structures like Expr and Stmt are packed into smaller sizes (16 bytes and 32 bytes on 64-bit), stored inline for more cache friendliness, and de-Boxed as much as possible.
  • Scope is optimized for cache friendliness.
