Eagle (Extensible Adaptable Generalized Logic Engine) is an implementation of the Tcl scripting language for the Common Language Runtime (CLR).
Try selecting one of the "Example Script Snippets" and then clicking the "Evaluate" button to evaluate it.
Most of the important commands from Tcl 8.4 are available, including full support for namespaces.
This demonstration uses an isolated "safe" interpreter (i.e. created with non-default options); therefore, some core language functionality (e.g. local files, network sockets, etc) is not available.
This demonstration is configured in such a way that all users, worldwide, share the same interpreter state (e.g. commands, procedures, variables, etc).
This is not the recommended deployment configuration for a web application; however, for the purposes of this demonstration, it does help to stress test the library and its sandbox functionality.
