Most of ES1 should be implemented (to some degree...), but see the TODO file for details. Also be aware that you probably haven't programmed in ES1 before and will find most modern conveniences (e.g. array and object literals) missing from the specification.
Support for ECMAScript 3rd edition is currently (slowly) under way.
You need a modern C++ compiler that supports C++17 and CMake 3.7 or later. It has currently been tested with the following compilers:
- Visual C++ 2017 15.8.8 on Windows 10
- GCC 7.1.0 (x64 distribution from Stephan T. Lavavej) on Windows 10
- GCC 8.2.0 (on x64 Linux, Debian testing as of October 2018)
To run the tests build the
The interpreter is built in the
file on the command line or starts in REPL mode if no argument is given.
These steps should work for most people:
mkdir build cd build cmake .. # Here you may want to use e.g. CXX=g++-8 cmake .. cmake --build . cmake --build . --target check
The project is currently light on the documentation front, but here is what's available so far:
- Implementing a Garbage Collector in C++ about how the garbage collector was implemented
- Supporting ECMAScript 3rd Edition on the work being done to support ES3 (very incomplete)
Forget about it :) Feel free to raise an issue on GitHub, but don't expect anything to come of it.
