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

Changes since 5.8.5

• Optimize away return statements in lambdas also
• Allow conversions to bool in conditionals
• Don't allow class statements inside of scopes
• Properly error when a dynamic object non-function member is called

Changes since 5.8.4

• Fix order of operations for prefix operators
• Make sure atomics are initialized properly
• Remove parsing of unused prefix & operator

Changes since 5.8.3

• Fix case with some numeric conversions mixed with numerics that do not need conversion

Changes since 5.8.2

• Add support for reference of pointer return types

Changes since 5.8.1

• Allow casting to non-const & std::shared_ptr

Changes since 5.8.0

• Fix parsing of floats to be locale independent #250
• Various warning fixes on various platforms

Changes since 5.7.1

• Make all parser iterator operations range checked
• Parse in-string eval statements once, not once for each execution
• Fix parsing of operators (ie 1<-1 now parses)
• Fix variable scoping for functors
• Exception reduction
• Various object lifetime fixes
• Add JSON support for load / save #207
• Numeric overload resolution fixes #209
• Fix long long #208
• Add octal escapes in strings #211
• Fixed sizing of binary literals #213
• Added support for != with bool values #217
• Various value assignment vector fixes
• Fixed broken hex escape sequences from @ChristianKaeser
• Multiply defined symbols fixes #232 @raptorfactor
• Add add_class helper #233 @vrennert
• Cheatsheet fixes #235 @mlamby
• Fix parsing of strings inside of in-string eval statements
• Allow lower-case global keyword
• Enable thread-local on MSVC (should be significant performance boost)
