Basically what I'm trying to accomplish is rapid manual sorting of lots of notes and snippets of text.
What I would like to it mark a set of registers, (basically headlines in org-mode) for example
1-Tasks 2-Inbox, 3-Reference, 4-Someday
Then I want to highlight bits of a messy notes file, invoke a function, and have it kill the selection, yank it to one of the marks, and then return to the place i was before to process more snippets. So far I know I need to use:
(evil-paste-after COUNT &optional REGISTER YANK-HANDLER)
but not sure exactly how to structure the function.
It sounds like you want to use org-refile with some custom targets?

The TLDR is the code:
(while (?????)
(org-next-visible-heading 1)
(org-todo 'todo)
)
What should I put in the condition ????? in order to stop at the end of the file, or after the last visible heading?
The longer context:
I'm using trying to use elisp to modify org-mode files for emacs. I'm new to elisp and finding it hard to find the relevant documentation for some basic things.
I want to iterate over the headings in an org-mode buffer and modify the status (i.e. todo) keyword. I've seen it suggested that if I want to modify the buffer, it is better not to use org-element-map but instead to use something like org-next-visible-heading or org-forward-same-level, and at each point use org-todo to modify the heading.
I know how to write a while loop, but I don't know how to write the condition as I haven't been able to find out how to detect if I'm at the end of the buffer, even though this seems to be a trivial thing to want to do.
I'm happy to be told there is a better approach to my problem but I would still like to know how to detect the end of a buffer in general.
Rather than looping, you can use org-map-entries. Here is an example, pretty much from the doc, that marks each headline as a TODO item:
(org-map-entries '(org-todo "TODO") t 'file 'archive 'comment)
It specifies a function to apply to each headline: (org-todo "TODO"); no tag or property matching; file scope; and skips archive and comment headlines.
Read the linked doc and also do C-h f org-map-entries, but don't get too scared by the doc string of the function: org-map-entries is very powerful, but it will take some time to understand how to do things with it and harness its power.
With Emacs, how can I automatically create comments titles like this one:
;;###############################################################################
;; title
;;###############################################################################
The purpose is to comment code (in this case Emacs configuration file) by sectioning the code in a clear way. I don't want to do this by hand because it takes time and it's often not perfectly centered.
M-x comment-box
is the solution
Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections.
Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode.
[Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]
AUCTeX does folding: http://www.gnu.org/software/auctex/manual/auctex.html#Folding
A popular complaint about markup languages like TeX and LaTeX is that there is too much clutter in the source text and that one cannot focus well on the content. There are macros where you are only interested in the content they are enclosing, like font specifiers where the content might already be fontified in a special way by font locking. Or macros the content of which you only want to see when actually editing it, like footnotes or citations. Similarly you might find certain environments or comments distracting when trying to concentrate on the body of your document.
With AUCTeX’s folding functionality you can collapse those items and replace them by a fixed string, the content of one of their arguments, or a mixture of both. If you want to make the original text visible again in order to view or edit it, move point sideways onto the placeholder (also called display string) or left-click with the mouse pointer on it. (The latter is currently only supported on Emacs.) The macro or environment will unfold automatically, stay open as long as point is inside of it and collapse again once you move point out of it. (Note that folding of environments currently does not work in every AUCTeX mode.)
In order to use this feature, you have to activate TeX-fold-mode which will activate the auto-reveal feature and the necessary commands to hide and show macros and environments. You can activate the mode in a certain buffer by typing the command M-x TeX-fold-mode RET or using the keyboard shortcut C-c C-o C-f. If you want to use it every time you edit a LaTeX document, add it to a hook:
(add-hook 'LaTeX-mode-hook (lambda ()
(TeX-fold-mode 1)))
If it should be activated in all AUCTeX modes, use TeX-mode-hook instead of LaTeX-mode-hook.
Once the mode is active there are several commands available to hide and show macros, environments and comments...
I'd like to quickly move point to a function in my Emacs buffer. I'd like to run some function and get a prompt asking me for the function name, with completion provided for every function defined in the current buffer.
I generally use etags to navigate around, but sometimes I'm looking for a framework method that's been overridden in several files. In these cases, I can find the file I need but then I'd like to quickly jump to the function there. There is a similar feature in TextMate where you can select a definition from a list in the bottom right of the editor.
Just to jump around functions in the current file? Use imenu. It's the simplest and lightest of all the alternatives listed so far and might be enough for what you want. It's also built into Emacs and has minimum setup hassle. It features graphical and textual interfaces. Anything extra and you'll be better off using one of the other excellent suggestions made here.
speedbar comes standard, and gives you a collapsible menu for each file in the current directory, by default middle clicking on an entry for a function definition jumps to that def. With emacs23 this was changed to the more normal leftclick.
You can use etags-select to select from multiple matching tags. But the answer to what you asked is imenu.
Icicles is probably closer to what you are looking for:
http://www.emacswiki.org/emacs/Icicles_-_Tags_Enhancements
It's an enhancement to etags and includes (among other things) the file name with the tag so you can tell if it's the one you are looking for.
try CEDET. It is a bit difficult to set up the first, but here is an excellent tutorial: by Alex ott
And when he gets installed, you can use semantic-complete-jump. pressed tab couple times, and it is also brings up symbol definitions.
If M-. brings up the wrong method, you can type C-u M-. to find the next one with the same name.
global gtags is very good
To navigate within the current file or a set of files that you select, you do not need a TAGS file. You can use Imenu. But it is better to use Icicles imenu commands.
Why? Because they let you use completion. Substring, regexp, prefix, or fuzzy completion. Combine simple patterns to match, or subtract them.
Command icicle-imenu is bound in Icicle mode to C-c =. Butyou can also look up just a command or just a non-command function (non-interactive), using command icicle-imenu-command or icicle-imenu-non-interactive-function.
These commands are multi-commands, meaning that they are actually browsers: you can trip among function definitions using keys C-RET or C-mouse-2 (direct jumps) and C-down (cycle). Hit RET or click mouse-2 to settle down at a final destination.
I use C-M-a and C-M-e to jump between the beginning and end of functions.
Otherwise, open up Speedbar and click the + icon next to a file name to view a list of functions contained in the file. Then click on the function names to jump to them directly.
How can I make Emacs to complete words that are in C include files ?
#include <stdio.h>
int main(){
print//<-- this is where I want it to complete printf
What's the simplest way? (something simpler than Cedet)
First generate tags for the source and include files you'd like to be able to autocomplete for. See my blogpost for tips on using tags if you didn't use tag tables before.
Now if you have a TAGS table that includes the stdio.h, then you can autocomplete 'printf' using the command `complete-tag'.
Perhaps bind `complete-tag' to a key:
(global-set-key [f3] 'complete-tag)
Unlike complete-tag, dabbrev-expand, or hippie-expand (which does dabbrev-expand like things), the CEDET suite does exactly what the question describes. When asked to perform a completion, it looks and sees that you have included stdio.h, and then looks there for possible completions.
CEDET does a lot of other things related to completion as well which will provide very focused and correct suggestions, not just vaguely similar suggestions. A side affect is that CEDET takes more effort to setup. You need to teach it where you include files are, for example, and sometimes how to deal with macros, and what the project you are working on is like.
There is more detail on this here:
link text
You might want to try out M-/ (dabbrev-expand). This command attempts to complete the identifier immediately preceding the point (ie, where your cursor is) using the contents of the current buffer and then the contents of other buffers of the same mode. If the first completion offered isn't the one you want, just keep typing M-/. If you have the habit of keeping a single emacs session open continuously (which, if you don't have, you should really acquire), and have a handful of files from the current project open, you're quite likely to be able to find an the expansion you want for any particular prefix.
So, to answer you're original question, M-/ will find the printf completion you're looking for if (a) you've used printf anywhere else in the buffer you're editing, or (b) it appears in any other .c or .h file you have open in emacs.
You might also try hippie-expand, which has additional options regarding where it looks for completion information. I bind M-/ to hippie-expand, and then modified the order of the elements in hippie-expand-try-functions-list as follows:
(global-set-key (kbd "M-/") 'hippie-expand)
(setq hippie-expand-try-functions-list '(try-expand-dabbrev try-expand-dabbrev-all-buffers try-expand-dabbrev-from-kill try-complete-file-name-partially try-complete-file-name try-expand-all-abbrevs try-expand-list try-expand-line try-complete-lisp-symbol-partially try-complete-lisp-symbol))
This makes hippie-expand act like the normal M-/ at first, but repeated presses will yield more possible expansions.
