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


  • 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

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 5.7.1

  • 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)
