I'd like to have a folding-mode (like org-mode or outline or hs-minor-mode) mode for diary entries.
For example, I'd like a quick overview of the diary entries - date, time, etc. but hide the following (indented) detail lines. Then, I'd like to be able to click on a line in the diary to expand/collapse it (hide/show details). I tried M-x hs-minor-mode in a diary file but it does not seem to recognize the diary file format ("Diary Mode doesn't support Hideshow Minor Mode")
In M-x calendar, when I view the entries for the day, I'd like that view also collapsible.
I know org-mode has agenda management but I've not tried it; I'm used to M-x calendar, M-x diary, and icalendar to import .ics files in email into my diary.
Consider filing an enhancement request, using M-x report-emacs-bug. (Yes, that command is also for enhancement requests.)

I've spent a whole day on this now. Say I open emacs and press C-c p p to open projectile-switch-project then RET to select a project, emacs opens a new window horizontally (on top of the previous) with the current buffer.
What I need is for projectile to use the already existing window and not open a new one. I've gone through every single line of my config and can figure out what is causing it.
I'd have posted my config but it's split over multiple files which will make it impractical to link to here.
The related packages I can think of which I use are:
projectile,
ivy swiper counsel - trilogy
What I've tried so far is start emacs without loading (ivy swiper counsel) and also I've tried replacing all my projectile code with bare minimum:
(use-package projectile
:ensure t
:init
(projectile-mode +1)
:bind (:map projectile-mode-map
("s-p" . projectile-command-map)
("C-c p" . projectile-command-map)))
which didn't work either.
I'm not expecting any specifics since it's a hand crafted config however I'm hoping for general pointes as to where to look for the possible cause.
I'm researching more to see if i can find a better way for you, but this is what i have so far...
If you want to look around the customization options just type M-x customize. I found a ton of options you can browse through. Projectile was listed under "Convenience" and frames/windows were listed under "Environment". You can also search packages you might be interested in for more customization if you have MELPA installed.
Considering the way that buffers and windows work I don't think you can just replace the content inside the buffer with the content of another file. I think (or at least how I've been using Emacs) you will always open a new buffer to open a file and close old buffers if needed.
From what I was reading, buffers are like interfaces between Emacs and the file you're peering into. It sets up a connection, points to the file, and creates a name for the buffer (usually from the file name unless you change it). Something I find interesting is you can even have multiple buffers open to the same file and as you type on the screen in one buffer the text should show up in the other buffer in real time.
I was reading some documentation on it and I think the command you're looking for is C-x C-f or C-x d, which opens DiredMode. The first one opens your home directory and the second opens the current directory for the file in your selected buffer. This will open a mini-buffer to search through files and when you choose the file it should open the file in a new buffer on top of the buffer you were looking at initially.
Then you can use C-x b to list and move between other buffers that are already open.
Also, M-x projectile-find-file is a command you can use to search files and get the same outcome. I don't have that set to a key-binding so I don't know if there is a default, plus I'm using Spacemacs with evil-mode, so not everything is the same as original Emacs.
Also, maybe look into extension you can get from MELPA like Treemacs
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
I have a directory "a" with a set of templates, for instance
$ ls a
b bcc cc ccdd
I would like to implement a keyboard shortcut in Emacs that will show a buffer with the template names, similar to dired or buffer-menu and then be able to select a template name by using arrow keys or mouse. Then insert the selected template into the current buffer at point.
How can this be done?
To augment Chris' answer with a little code, here is a small wrapper around ido-insert-file:
(require 'ido)
(defvar so/template-directory "/tmp/templates"
"Directory where template files are stored")
(defun so/insert-template ()
(interactive)
(let ((default-directory so/template-directory))
(ido-insert-file)))
This allows you to run (or bind a key to) so/insert-template no matter what directory you are currently in. Obviously set so/template-directory to your preferred directory.
insert-file, bound to C-x i by default, can insert a file into your buffer at point, but it doesn't give you a nice menu. Both helm and ido enhance this behaviour.
helm does not come with Emacs, but it can be installed via MELPA. When helm-mode is active, insert-file uses Helm's narrowing features. Once you're in the a directory, the up and down keys may be used to select a file, and Enter will insert it.
ido is shipped with Emacs. When ido-mode is active, C-x i is rebound to ido-insert-file. Once you're in the a directory, the left and right keys may be used to select a file, and Enter will insert it.
Both tools are excellent, both can be used in many other situations, and both offer effective filtering and navigation. Try one or both and use whichever you prefer.
Everything #Chris said about Helm and Ido is true also for Icicles, and with better "narrowing" features and on-the-fly sorting in different orders.
There is nothing extra to do --- just load Icicles and turn on Icicle minor mode. Whenever you use standard command insert-file (bound to C-x i) you get the behavior you requested for free. This behavior is in fact available for all completion in Emacs. In Icicle mode, standard commands become menus you can use the arrow keys on, etc.
In addition, your question title asks to be able to "select a set" of files. You can do that easily in Icicles, but not otherwise. IOW, selection is also multi-selection.
(However, I suspect that your question is mistitled, since the text describes something different, and I doubt that you want to insert a set of files. You probably meant that you want to select one file name from a set of file names. Consider retitling the question, if so.)
When working with org-mode I would like to edit a code block in a specific window.
While org-mode does allow some customization with respect to which window a code block will open in, it is quite limited. The four options currently available for the org-src-window-setup variable include current-window, other-window, other-frame, and reorganize-frame. However, these do not accomplish my goal.
I would like to either be able to specify a specific window and/or use windmove-right, for instance, from the windmove package. At the moment, I can only specify one of the four options above. Also, other-window, does not actually go to the other window. Instead it opens a vertical split and creates a new window. At least in my setup.
Is there a way to alter what options the org-src-window-setup variable accepts? Or perhaps there is another solution?
You are looking for:
C-c '
which opens a new window for code editing. You insert the code in your file by saving the buffer
C-x C-s
or by closing the code buffer with
C-c '
For code block there is a shortcut (yasnipet)
<s [tab]

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...
