I am new to Emacs and presently I am using it heavily for LaTeXing.
Please help me out with the following customizations:
How to scroll continuously in doc-view-mode? I have
(setq doc-view-continuous t)
in my .emacs file. This enables scrolling through the pages, however, the pages "jump" to the next one. I do not like reading to the bottom of the screen. Is it possible to resolve it?
I invoke doc-view using C-c C-c and the PDF loads into a new window. Is it possible to load it in a new frame?
I have used
(menu-bar-mode -1)
(tool-bar-mode -1)
(scroll-bar-mode -1)
in my .emacs file. This works fine. However, the first line is just below the top screen. Can I create some margin ONLY on top?
How do I copy/paste from Emacs to other application, like a browser? I couldn't copy the code above using C-w in Emacs and then Ctrl-v in Iceweasel (browser). I had to use Kate, sadly. (This I realized while typing this question!)

You should be able to scroll "line by line" with C-n and C-p.
I do not know that mode (I use tex-mode), but what you probably want is to find out how C-c C-c is invoking doc-view and use it with other-window, for example:
(defun new-frame-dvi-file ()
(interactive)
(split-window-right)
(other-window 1)
(tex-view))
I could not find anything that sets a top margin ONLY, but found this:
(set-frame-parameter nil 'internal-border-width 10)
You can share clipboards with this:
(setq x-select-enable-clipboard t)
Anyway, even if it sounds really boring, sometimes it is really useful to take a look at the manual. Sometimes you don't need to read it all and you can find the answer quickly ;-)
Hope it helps!
I want to open the currently editing html page in a browser and then switch the
window system focus to the browser on a key press. I am using gnome desktop environment.
Below is the code (except the focus switching)
(defun open-in-browser()
(interactive)
(save-buffer)
; switch the windowing systems focus to the browser
(let ((filename (buffer-file-name)))
(browse-url (concat "file://" filename))))
(global-set-key (kbd "<f5>") 'open-in-browser)
I have tried using the lower-frame function and suspend-frame function,
both hides the emacs-frame which is not desired since i will not be able to see the code,
apart from that i have to type ALT-TAB twice to swith to emacs-frame again.
How to switch to another application (just like emulation of ALT-TAB in gnome) using
elisp.
The function you are looking for is probably unfocus-frame but it is obsolete. You need a cooperating window manager in order to actually do what you ask.
You cannot do what you are asking for. Changing the focus is the responsibility of the window manager and emacs cannot do it. You could
call an external program from emacs to do what you want
create a keybinding that would combine <f5> and ALT-TAB
There are programs which can be used to control window managers from the command line, so that you can call a command from elisp to activate windows and stuff.
One such program is wmctrl. I don't know if it works with Gnome, you should try it.
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 got speedbar set up and working, but I want to change it so a single click (Mouse-1) will allow me to go inside a directory. I've already googled around and looked at the relevant docs:
The mouse bindings are:
Mouse-1
Move cursor to that location.
Mouse-2
Double-Mouse-1
Activate the current button. Double-Mouse-1 is called a double click on
other platforms, and is useful for windows users with two button mice.
So, basically I've been trying to find how to map Mouse-1 to the function currently bound to Mouse-2, but only inside the speedbar frame. The closest I've found to something to do that is an ecb setting:
(setq ecb-primary-secondary-mouse-buttons 'mouse-1--C-mouse-1)
but I'm not using ecb, I'm just using speedbar. Maybe there's some other way to do it?
Adding this line to `speedbar-file-key-map' should do the trick:
(define-key map (kbd "<down-mouse-1>") 'dframe-click)
If you don't want to edit speedbar.el directly, you can use e.g. a hook.
The emacs tabbar.el package adds (buffer)tabs to each window and comes standard with aquamacs and can be added to emacs23 with the emacs-goodies-el package.
Are any of you hardcore emacs users actually using tabbar? I'm sort of used to having tabs, but I would like to know if working without them could be more productive, and if there are other ways besides checking your bufferlist (C-x C-b) to get an overview of your current project files.
As a side note, I really like textmate's project drawer (and tabs), but anything similar in emacs looks just plain hideous.
I've tried using it, but I felt it constraint my workflow rather than improve it. There are a lot of excellent Emacs modes to help with the organization of many buffers and I simply don't feel mapping buffers to tabs is one of those ways.
Just think about the most basic scenario - a lot of tabs. How different programs deal with it - limit the maximum tabs(IntelliJ IDEA); enable tabs bar scrolling(Firefox); infinitely reducing the tabs size(Google Chrome); creating rows of tabs(IntelliJ IDEA)... None of this solutions is that great and by not having tabs in Emacs we have one less problem to worry about. At least this is my subjective opinion - others will most certainly disagree... I personally need nothing more than ido and and iswitchb.

Ya, I use tabbar, along with sr-speedbar.
I customize tabbar to show files in specific groups, and mod some keybindings to make navigating the files easier.
FWIW, here's the relevant section from my ~/.emacs:
(require 'tabbar)
; turn on the tabbar
(tabbar-mode t)
; define all tabs to be one of 3 possible groups: “Emacs Buffer”, “Dired”,
;“User Buffer”.
(defun tabbar-buffer-groups ()
"Return the list of group names the current buffer belongs to.
This function is a custom function for tabbar-mode's tabbar-buffer-groups.
This function group all buffers into 3 groups:
Those Dired, those user buffer, and those emacs buffer.
Emacs buffer are those starting with “*”."
(list
(cond
((string-equal "*" (substring (buffer-name) 0 1))
"Emacs Buffer"
)
((eq major-mode 'dired-mode)
"Dired"
)
(t
"User Buffer"
)
)))
(setq tabbar-buffer-groups-function 'tabbar-buffer-groups)
(global-set-key [M-s-left] 'tabbar-backward)
(global-set-key [M-s-right] 'tabbar-forward)
There's lot's of other tips on emacswiki:
http://www.emacswiki.org/emacs/TabBarMode
no.
I use iswitch-b
C-x b "first few letters of buffer", then C-s to rotate to the specific file I want takes me under 2 seconds without me having to move hand to mouse.
No. I could possibly be convinced to try it again with the right customisation, but by default it's pretty useless for me, as I habitually have in excess of 100 buffers open. ibuffer with its filtering and grouping is the best way for managing large numbers of buffers that I've tried.
I like to use speedbar for quick buffer navigation. I have in my .emacs
(speedbar-change-initial-expansion-list "buffers")
(global-set-key [f8] 'speedbar-get-focus)
so when I hit F8, a new frame pops up with a list of open buffers, there you can move point over the buffer you want to select and to activate it. One more F8 goes back to the main frame.
tabs are not reserved for mouse users. look at vim possible workflow: gt to go next tab, or gT to go previous. Say you've one dedicated window for vim: you might easily switch from one buffer to another. Yes, tabs are probably for users with few buffers. if you have hundreds, this won't work.
Quite frankly, you'll find better editors than emacs when speaking of tabs, menus and toolbar. Emacs clearly encourages you to use your keyboard and leave your mouse asleep.
Tabbar or any other tab management tool will have difficulties when you'll have lots of buffers opened. You also don't want to show all your buffers in tabs. Having to remove your hand from the keyboard to grasp the mouse and click on a tab and then remove your hand from the mouse and put it onto the keyboard is clearly a waste of time when a simple keystroke could be used instead.
The best thing you could do to your emacs and to you is to have the following configuration in your .emacs :
(menu-bar-mode -1) ;hide menu-bar
(scroll-bar-mode -1) ;hide scroll-bar
(tool-bar-mode -1) ;hide tool-bar
That will force you to forget the old way of doing things using a mouse (like using tabbar, or menus...), and to use your fingers instead.
Up until now, I haven't tried it, but before I switched back to GNU Emacs from XEmacs, I used the XEmacs tabs very heavily. I found that when I had many source files open, it was one of the fastest ways to jump to the correct file.
Now that I know about tabbar, I am trying it; and so far, I like it.

Tabs are really only useful if you use the mouse, and one of the main benefits (to me) of Emacs is that I can avoid the mouse.
So, no, tabbar isn't useful in general.
I did find the tabs useful when I was browsing web pages (using w3m), but I was using the mouse in that case...
Tabbar looks like it is godforsaken
So what about elscreen?
Can be found via http://melpa.milkbox.net/#/elscreen - or installed emacs-elpa (or melpa).
Elscreen is very useful for me.
C-x b<RET> always gives you the last edited buffer. And what do you do with tabs ? Mostly switch back & forth between two files. There you go.
