How does one tell when a command is executed from the minibuffer?

How does one tell when a command is executed from the minibuffer?

[Alan Mackenzie]

Hello, Emacs.

How does one tell when a command is executed from the minibuffer, e.g.

    M-: (foo)

, as contrasted with executing it from a file, e.g. by loading that
file, or with C-M-x or C-x C-e?

Something like (current-buffer) ought to do it, but `current-buffer'
"lies" when the current buffer is actually the minibuffer.

There is no such thing as "executed from the minibuffer".  The
expression may be *read* from the minibuffer, but that happens before
eval-expression is called to evaluate the expression.

Thanks for the clarification.  How does one tell whether an lisp
expression which has been read, and is in the course of being evaluated,
was read from the minibuffer?

First you need to explain what you are after.

You don't.  You step back and look for another problem to solve.
