EEL Features

• Designed for hard real time applications
• Implemented in portable C with very few dependencies
• C-like syntax
• Automatic memory management
• Dynamic typing
• Functions are objects (Can be passed by reference)
• Generic argument multiplexing, even inside expressions
• Loop constructs support break, continue and repeat
• Named loop bodies for break, continue and repeat
• Variable length argument lists...
  • Required arguments
  • Optional arguments
  • Tuple arguments
• Exception handling...
  • try..except statements
  • untry to debug code inside try blocks
  • except blocks are optional
  • throw statement that can throw any object
  • retry statement to re-run try block
• Built-in high level types...
  • string (Pooled constant "Pascal strings")
  • dstring (Dynamic "Pascal string")
  • array (Array of dynamic typed values)
  • vectors (Fast, compact arrays of numeric types)
  • table (Table of <key, value> tuples)
  • file and memfile (Disk and memory files)
  • directory (Disk file directory)
• Modules:
  • Modules are objects
  • Imported modules can be wrapped in namespaces
  • EEL modules...
    • Can be imported at compile time
    • Can be loaded dynamically at run time
  • Native (C) modules...
    • Can be injected by host applications
    • Taste just like (in fact, are) EEL modules
• Integrated compiler with comprehensive error messages
• EEL code can generate and compile EEL code at run time
• Fast, register based, variable instruction size VM
• Light weight interface to call C functions
• Simple interface to call EEL functions from C
• True data types can be added at run time
• Low cost of entering and leaving the VM
• Comes with EELBox, a binding to SDL with some add-ons
