Embed tclsh in tk

Question

Is it possible to embed tclsh in Tk? I'm trying to send commands from a user interface made by tk and observe its results.

If so, could you help to pose some simple codes for this? Thank you very much.

Answer 1

You should take a look at the interp command to create and manipulate tcl interpreters:

You should be able to first create a interpreter this way and evaluate strings from your Tk Application.

1. create a interpret
2. Get the to evaluated string from your Tk application
3. evaluate the string in this interpreter

A minimal example to create an interpreter and evaluate a a string in it:

interp create a
set str "puts \"Hello World!\""
interp eval a $str
