I realized that it has been asked with some weird titles in Stackoverflow. I can not delete this post cause it already has an answer. if you are interested see following:
Can I change the emacs fancy-startup-text?
How to load file into buffer and switch to buffer on start up in Emacs
Original Question:
I understand that it is possible to remove the Emacs splash screen! (" Unable to hide welcome screen in Emacs "). How can I change this welcome screen with my own welcome screen?
I believe you can use initial-buffer-choice, as documented here:
http://www.gnu.org/software/emacs/manual/html_node/elisp/Startup-Summary.html
User Option: initial-buffer-choice
If non-nil, this variable is a string that specifies a file or directory for Emacs to display after starting up, instead of the startup screen.

In this Tim Baldridge video (at 2.47) you can see he has arranged his emacs to have the echo buffer on the right of a horizontal split screen.
Now when I look at the cider shortcuts or even the emacs doco - I see nothing for this.
My question is: How do I split my emacs screen to have the echo buffer on the horizontal right?
Here is info.
If you want to have REPL on the right side, use C-x+3 (split vertically), then go to the right buffer (with C-x+o, for example), and switch to the REPL via C-x+b or C-x-b.
That video is not Emacs but Intellij Idea with the Cursive plugin. You will get that layout by default when starting or connecting to a REPL
I saw the feature shown and described below in Sublime Text and was curious to know how does one achieve it in Emacs?
A brief description of the feature:
Have a condensed view of the entire code/text file currently opened and highlight the region, in the very same condensed view, which is currently being viewed. Clicking on any part of the condensed view would bring that part in focus.
Although I know, almost certainly, that I would rarely use this feature since it would be, in my view, a estate hog, considering the fact that I have even had my scroll-mode disabled, but still I am curious to know how it can be done in Emacs.
And yeah I went through(skimmed) Sublime's feature list to find the name of the feature, so that I could then try to find it for Emacs, but couldn't. Therefore, another question: What's this feature called?

There is MiniMap package. From EmacsWiki:
Put minimap.el in your load path.
(require 'minimap)
Use M-x minimap-create in a buffer you’re currently editing.
Use M-x minimap-kill to kill the minimap.
Use M-x customize-groupRETminimap RET to adapt minimap to your needs.
Emacs 23 can view PDF files inside the editor which is great. However it also shows a welcome page, for every PDF page, like this:
How can I remove this welcome page? I understand Emacs is doing some processing for the PDF page, and it probably does not want the user to try to open the file over and over again while it is doing that, but I'd prefer and hourglass instead of a whole page.
I tried setting doc-view-conversion-refresh-interval to nil BTW, it didnt work.
I am on GNU Emacs 23.2.1 (i686-pc-linux-gnu, GTK+ Version 2.24.4).
Thanks,
WRT your answer, it sounds like you either edited the original file, or made a replacement copy of that entire library.
The first way will be lost when you update Emacs. The second way means you won't get any improvements to that library when you update Emacs. Neither is a very good option.
Instead you can tell Emacs that if and when it loads the original library, it should re-define that one function at that time.
This minimises the potential problems associated with upgrades, and does not require you to load the library unconditionally in your .emacs (which would increase your start-up time unnecessarily for sessions where you didn't load any PDFs).
(eval-after-load 'doc-view
'(defun doc-view-buffer-message ()
;; your definition here
))
I think you need to press C-c C-c
I found doc-view.el source for Emacs 23, and I removed the message from doc-view-buffer-message function. So now when PDF is loaded an empty page is shown which is less confusing, welcome page made it look like the PDF was loaded.
After the changes I did byte-compile-file on the el file, and at the end of my .emacs I load this overriding the original doc-view.
I've been using a copy of emacs (in a Debian VM I ssh to with putty) at work for a couple of months now, and up until now everything has been working brilliantly... but this morning I'm trying to edit a file in shell-script-mode, and am seeing some weird behavior with text around the cursor.
Basically, when I type the following ( [ ] represents my cursor):
export DATABASE[]
After I've typed the first few characters of the variable name the export statement disappears and the variable name aligns to the left margin, and all I end up seeing is (with the cursor out in the wilderness):
DATABASE []
If I then hit CTRL-L, the screen refreshes, and I see the text as it should be displayed... until I start typing, and then the buffer start acting strangly again (characters disappearing, moving, cursor ending up in the wrong place, etc)
I've not, to my knowledge, added anything to my .emacs file since this last worked as I expect it to, so I'm at a loss as to what could be happening here. It doesn't seem specific to sh-mode either - I've tested a few other file types and observed similar strange behavior. Are there any emacs afficianados out there who might be able to point me in the right direction to figure out what's wrong here?
Thanks in advance
I'm not sure what to suggest, but this sounds awfully like an issue with the terminal: I suspect that Emacs redraws the current line whenever it changes and I guess it tries to do so incrementally. If something's got out of whack with your terminal, then it seems quite plausible that the current word would get written at the start of the line (all Emacs sent) and your cursor would get abandoned "out in the wilderness" :-)
Obviously, this is a new change. Since it doesn't sound like the sort of issue that would be caused by Elisp configurations in your .emacs, you should check whether you've recently upgraded one of
PuTTY
Emacs version
SSH version (unlikely...)
Then maybe the relevant tool will have something in the changelog (which maybe you can disable via a config?)
One thing you could check: you say this isn't just SH-mode. Is it "any mode with syntax highlighting"? Maybe Emacs just sends over the wire the text with the current colour?
I had a similar problem of disappearing text using PuTTY / Emacs / Remote AWS Ubuntu when running ABCL LISP in a shell window.
The solution was: I had changed my foreground and background font colors (essentially reversed) in PuTTY but had neglected to change the bold fonts, so they were disappearing into the background.
I have recently started using doc-view in Emacs, but I am having quite a few problems with it. The main one is that I can't scroll down on pages. I can see the next or previous page using "n" or "p", but the commands to scroll up and down a page, which are supposedly SPACE and DEL, do not work. Well, to be fair, DEL works, but it goes to the previous page rather than scroll up to the bottom of the previous page. The result is that I can only see the top of the pdf pages, but not the bottom parts.
I tried changing the view to continuous, but that doesn't work either. This is what I tried changing:
I did check the customisations for doc-view, but the variables (or options, or whatever they are called) did not appear to me to be the ones which would solve my problem.
More information: I did manage to make SPACE and DEL work at some point, but I don't remember what I did, and I can't get it to work again. I am using Aquamacs.
Any ideas?
By the way, another problem I have is that doc-view causes Aquamacs to sort of crash, meaning it freezes everything, keeps "thinking", and I have to force quit Aquamacs to get it to work again. While this is not my main question, if anyone can tell me anything about this I would also appreciate.
Thanks!
EDIT: I tried what the answer below suggested, it didn't work, kept trying other things/commands, and then C-n and SPACE started working! I quit Aquamacs, started it again, opened a pdf document, and it is back to not working. Can someone please explain what is happening? How can I make this reliable?
(setq doc-view-continuous t)
This lets you scroll the whole document with mouse wheel(not just the current page).
To commands to scroll down are bind to:
C-n, down
not SPC
UPDATE:
SPC is rebound in docview mode. Can't reproduce you issue using GNU Emacs/Linux, can you invoke:
M-x doc-view-scroll-down-or-previous-page
