• v6.0.0 Changes

  February 22, 2017

  🔄 Changes since 5.8.6

  6.0.0 is a massive rework compared to 5.x. It now requires a C++14 enabled compiler

  Compiler Requirements

  • MSVC 2015 or greater
  • g++ 4.9 or greater
  • clang 3.6 or greater

  💥 Breaking Changes

  • 🏗 Instantiating a ChaiScript object now, by default, builds the stdlib in
    • This was done to address the most common support issues of loading stdlib dynamically at runtime
    • If you want the old behavior, use include/chaiscript/chaiscript_basic.hpp
  • 🏗 Headers have been reorganized to fully separate stdlib/parser/engine from each other (some faster builds)
  • Bootstrap functions no longer return a reference to the module added to (compile time savings)
  • It's now no longer possible modify AST_Nodes (compile time, runtime efficiency)
  • Function annotations no longer exist (simplifies code, reduces compile time, compile size)

  🆕 New Features Added

  • Modular optimization system; this can be accessed via the ChaiScript_Basic interface
  • Execution tracing capability; also accessed via ChaiScript_Basic interface
  • 🐎 range-based for loops for( id : container ) { } (much better performance than other loop types)
  • If-init expressions (ala C++17)
  • 👌 Support for passing r-value references to functions
  • 👌 Support for containing unique_ptr
  • ➕ Add helpers for exposing enum classes to ChaiScript
  • 👍 Allow typed ChaiScript defined functions to perform conversions on call #303

  👌 Improvements

  • Compile time improvements
  • Compile size improvements
  • 👀 Significant runtime improvements (see "Modular optimization system")
  • 📜 Significant parser improvements, both with parse-time and parser initialization time (Thanks @niXman)
  • 🛠 Fix type conversion to bool in conditionals

  👌 Improvements Still Need To Be Made

  • File location tracking has been rewritten; this currently means error location reporting is not as good as it was
  • ✅ Tracing capability needs to be tested and vetted

• v5.8.6 Changes

  February 22, 2017

  🔄 Changes since 5.8.5
