Jim Tcl: Small yet Powerful Open Source Tcl Interpreter

Jim Tcl is a small yet powerful open source Tcl interpreter designed to be easily embeddable and extensible. It implements most Tcl commands and has a compact C API for extension modules.

What is Jim Tcl — The Jim Interpreter?

Jim Tcl (also called Jim) is an open source, small-footprint implementation of the Tcl programming language. It was designed from the ground up to be easily embedded into other applications and extensible through C programming interfaces.

Some key features of Jim Tcl include:

  • Implements nearly all Tcl 8.6 commands and syntax
  • Small memory footprint suitable for embedding
  • Written in portable C89 code
  • APIs for creating new Tcl commands in C
  • Support for call frames and namespaces
  • Fast Tcl script execution
  • Built-in PDB debugger
  • BSD license allows unrestricted use in free or commercial products

Jim Tcl makes an excellent choice as an embedded scripting language for applications and devices. Its C APIs allow the base language to be extended for any purpose. Common uses include test harnesses, small-scale automation, command line tools, prototypes, and more.

The compact size of Jim Tcl makes it well suited for memory-constrained environments. It has been ported to a wide range of systems and architectures. Community packages are available to add advanced capabilities like SQLite, GNU readline, references, lambdas, and more.
