ELENA is a general-purpose language with late binding. It is multi-paradigm, combining features of functional and object-oriented programming. It supports both strong and weak types, run-time conversions, boxing and unboxing primitive types, direct usage of external libraries. Rich set of tools are provided to deal with message dispatching : multi-methods, message qualifying, generic message handlers. Multiple-inheritance can be simulated using mixins and type interfaces. Built-in script engine allows to incorporate custom defined scripts into your applications. Both stand-alone applications and Virtual machine clients are supported.

To acquire the source code clone the git repository:
git clone git://github.com/ELENA-LANG/elena-lang.git
The compiler code is implemented in C++ and does not require external dependencies. You just need Visual Studio 2019.
You have to add a path to BIN folder to the system environment PATH or copy elenavm.dll and elenart.dll to Windows\System32 folder.
To build the compiler under VS2019 you have to go to the root folder and type:
recompile19.bat
To build the ELENA libraries type the following command:
rebuild_lib.bat
To build ELENA samples type the following command:
rebuild_examples.bat
To build ELENA Rosetta-code samples type the following command:
examples\rosetta\build.bat
To run unit-tests type the following command:
lib_tests.bat
ELENA Project looks for programmers interested in learning the language and providing feedback.
If you've noticed a bug or have a question go ahead and make one!
Join design discussions or take part in general talks.
Good first issue is good starting point for a first-time contributors.
You may try to implement some of Rosetta code tasks which are not yet implemented
The ELENA source code is organized as follows:
bin binaries and shared libraries
bin\scripts scripts used by the script engine and VM console
bin\templates ELENA project templates
asm source for core routines implemented in assembly
dat\sg language grammar file
dat\og language optimization rules
doc some documentations
elenasrc2\elc source for the compiler
elenasrc2\elenart source for the run-time shared library
elenasrc2\elenasm source for the script engine
elenasrc2\elenavm source for the virtual machine
elenasrc2\gui source for IDE
elenasrc2\tools source for ELENA utilities
examples ELENA examples
src50 source for ELENA libraries
