Tip of the day

Tip of the day

[Adam]

There was a note on planet.emacsen.org regarding a 
"Tip of the Day" prompt. 

I can't see any totd in the Emacs manual, or via 
C-H help. It sounds a nice idea though. 

Can anyone advise if or where there's a 
Tip of the Day package for Emacs.

The code was provided in the blog article. Here it is:

--8<---------------cut here---------------start------------->8---
(defun totd ()
  (interactive)
  (with-output-to-temp-buffer "*Tip of the day*"
    (let* ((commands (loop for s being the symbols
                           when (commandp s) collect s))
           (command (nth (random (length commands)) commands)))
      (princ
       (concat "Your tip for the day is:n"
               "========================nn"
               (describe-function command)
               "nnInvoke with:nn"
               (with-temp-buffer
                 (where-is command t)
                 (buffer-string)))))))
--8<---------------cut here---------------end--------------->8---

Thanks Tassilo. 

Forgive my ignorance, I suppose really I was wanting 
to give that function a test-run, by not including it 
in my startup file, but by entering it into my Emacs 
session. Then running (totd) or M-x totd  

Then including in .emacs, and binding to a key later. 

Is this possible, by entering the function into 
the *scratch* buffer and evaluating it somehow. 

Or should I be in a buffer of a more of an 
interactive mode?

Yes, if you copy the function to scratch, move the cursor to the line
after the end of the function, you can evaluate it with C-x C-e. You can
then run the code with M-x totd <ret> or M-: (totd) <ret>.

Note that you should probably change the 'n' values in the concat
strings to '\n' to get properly formatted output.

Ah ha.  I was placing the cursor at the opening 
bracket of the function - and getting an "End of 
file during parsing" error.    

[Maybe its the Slime C-x C-e that works at either end].

Yes - correcting the 4 instances of that make 
it comfortably legible. 


Wonderful. Many thanks.

Hi,
Thanks for describing this here, I wondered about the n's ... Now it
really looks good!

Ups, I simply copy&pasted it from the web page planet.emacsen.org. ;-)

Tip of the day: buffer navigation with global mark

[Kai Großjohann]

It is well known that you can do C-SPC at various spots in a buffer,
and subsequently, C-u C-SPC takes you back.  (Repeat to go further
back.)  Kinda like the web browser history.

But it is less well known, I think, that the global mark ring exists
and can be navigated in a similar manner.  If the previous mark was
set in another buffer, C-SPC also pushes mark on the global mark
ring.  This can be used with C-x C-@ to jump back to it.

So you can do C-SPC, then go to another buffer and do stuff.  Then
later on, C-x C-@ will go back to the original buffer.

It might land you in the wrong spot, though.  But C-u C-SPC will cure
that.

I've been collecting them; maybe the splash screen thing can be
implemented someday.

I'd prefer his brains
