ChaiScript Files

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
