ChaiScript v6.0.0 Release Notes
Release Date: 2017-02-22 // about 7 years ago-
🔄 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
