Question

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.

Answer 1

Use rename to delete a proc

rename myproc ""

Example:

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