How do I remove a Tcl procedure?

How do I remove a tcl procedure?

One can

  • unset a variable,
  • override an alias with interp alias {} myproc {} otherproc,
  • override a proc with one defined inside another namespace with namespace import -force.

But I did not find a way to make a procedure unknown.

Solution

  • Use rename to delete a proc

    rename myproc ""

    Example:

    % proc myproc {} {
    puts "hello world"
}
% myproc
hello world
% rename myproc ""
% myproc
invalid command name "myproc"
%
