7 About JIM-Tcl

OpenOCD includes a small “TCL Interpreter” known as JIM-TCL. You can learn more about JIM here: http://jim.berlios.de

• JIM vrs TCL
  JIM-TCL is a stripped down version of the well known Tcl language, which can be found here: http://www.tcl.tk. JIM-Tcl has far fewer features. JIM-Tcl is a single .C file and a single .H file and impliments the basic TCL command set along. In contrast: Tcl 8.6 is a 4.2MEG zip file containing 1540 files.
• Missing Features
  Our practice has been: Add/clone the Real TCL feature if/when needed. We welcome JIM Tcl improvements, not bloat.
• Scripts
  OpenOCD configuration scripts are JIM Tcl Scripts. OpenOCD's command interpretor today (28/nov/2008) is a mixture of (newer) JIM-Tcl commands, and (older) the orginal command interpretor.
• Commands
  At the OpenOCD telnet command line (or via the GDB mon command) one can type a Tcl for() loop, set variables, etc.
• Historical Note
  JIM-Tcl was introduced to OpenOCD in Spring 2008.
