I have some difficulties to understand how Lisp wanted to receive the arguments. When I look into the documentation about arguments in functions, I need to name the arguments exactly as in the source code, when calling the same function.
When I look into the documentation of Emacs function
indent-region, I get the following:
= runs the command indent-region, which is an interactive compiled Lisp function in `indent.el'. It is bound to =, <menu-bar> <emacs-lisp> <indent-region>, C-M-\. (indent-region START END &optional COLUMN) Indent each nonblank line in the region. A numeric prefix argument specifies a column: indent each line to that column.
Then I create a function, that pass the arguments to the function itself, as described in the documentation:
(defun foo (start end) (interactive) (indent-region start end) )
I see no difference when comparing with how another custom functions handles the functionality. When I visually selected a region, and call the function, I got the error that the arguments are of the wrong type.
So this led me to wonder why the
end arguments are not accepted in this case?
