Release 6.0.0

2017-02-22T23:04:11Z

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

Release 5.8.6

2017-02-22T22:39:17Z

Changes since 5.8.5

Optimize away return statements in lambdas also
Allow conversions to bool in conditionals
