scScript is a powerful but simple to use C-like scripting language. It compiles to efficient bytecode (that it shows) and runs in a fast virtual machine. scScript is integrated with scEmacs, a small display editor for I/O.
Everything is written in C, runs on 64-bit Linux, is easy to customize, port, extend, and embed!
Go to Online Manual for a complete guide,
or to see sample code (Intro 1).

- Has familiar C-like syntax and operators.
- Provides simple pointer-less scripting with:
- 64-bit integer and double floats
- Immutable UTF-8 text strings
- Arrays that grow automatically
- Dictionaries (flexible assoc lists)
- External structures (3 flavors)
- Nested function declarations and first-class closures
- Variadic Pass-by-value and Pass-by-reference args
- Subordinate scripts
- Has stackful asym coroutines and non-local exits.
- Compiles to optimized bytecode running in a small VM.
- Can display line-by-line source AST and bytecodes.
- Optimizes tail call recursion (no stack frame).
- Uses Mark/Sweep GC as well as Ref Counting.
- Provides a powerful (text) pattern matching system.
- Readily interfaces to C routines for package libs.
- Employs slab-based low-level memory management.
- Only uses

scEmacs is an integrated editor with:
- Multiple buffers, panes, and windows,
- Color source code display,
- UTF-8 text, Undo, Kill Ring, and Mark list,
- Incremental search, query replace, and auto completion,
- Mouse-based ops, scrolling, and even Unix Sel insert,
- Pop-up window/menu facility for enumeration/selection,
- Specialized commands to drive scScript.
