Dired+ Not showing details anymore? - emacs

I just updated to the most recent version of Dired+ and Emacs (from a nightly build) and, for some reason when I open Dired on any path, I don't see details (e.g. file size, permissions, size, etc.)
Has anything changed on Dired+ in the latest version? How do I restore the details view? Here is a snapshot of what I get now:

Taken from the package documentation.
Starting with Emacs 24.4 (I assume what you got in nightly), listing details are hidden by default.
Use ( anytime to toggle this hiding. You can use option
diredp-hide-details-initially-flag to change the default/initial
state. See also option diredp-hide-details-propagate-flag.
If you have an Emacs version older than 24.4, you can use library
dired-details+.el (plus dired-details.el) to get similar
behavior.
How to find it quickly:
M-x find-library enter dired+enter C-s details

You can just press C-( to toggle it;

What's this minor mode -- indicating recent change in left margin

This is the emacs init file from https://github.com/purcell/emacs.d/, does anyone knows what's the package make the highlight of recent changes in left margin? Thanks.
Also, this emacs profile has a function, when the cursor stays on a word (goto-char in the figure) for around 3 seconds, all of its other occurrence in the buffer are highlighted as well. Please also let me know what's the packages achieving that.
Appreciate the help.
I can't be sure, but these are likely matches since I found both on the list of packages that are installed with the config (elpa folder).
The highlight after 3 seconds is a feature provided by the highlight-symbol package, available through Melpa. You can customise the amount of time it requires to highlight the symbol with the highlight-symbol-idle-delay variable.
The other is diff-hl, which doesn't highlight recently changes, rather it highlight lines that are uncommited, if the file is under a particular version system (git, most likely). Also available on melpa
Most likely it is the diff-hl mode. The mode highlights uncommitted changes in the current file on the margin or the fringe. It is included in the config you linked to: https://github.com/purcell/emacs.d/blob/master/lisp/init-vc.el.

Autocompletion from the keyboard in Emacs CEDET/semantic

Looking a the different methods for completion in CEDET semantic (fresh version from the Bazaar repository), I see I have the following options (keyboard bindings as suggested by Alex Ott in his config file)
C-c ? (semantic-ia-complete-symbol)
C-return (semantic-ia-complete-symbol-menu)
C-c , l (semantic-analyze-possible-completions)
However, none of them seem to give me the option to choose between the possible completions conveniently using the keyboard.
For example, (semantic-ia-complete-symbol-menu) opens a menu where I can choose between the different options, but as far as I can tell it requires me to use the mouse (I tried C-n, C-p, M-n, M-p to navigate the menu with no success).
On the other hand (semantic-ia-complete-symbol) opens another buffer with the options. I can also use the mouse to choose the desired autocompletion, but I would like to use the keyboard instead.
Also, in previous versions of CEDET, there was a variable (semantic-complete-inline-analyzer-displayor-class) that allowed me to choose between several options for autocompletion (e.g. (semantic-displayor-ghost), or a more elegant overlay as a tooltip), but this variable does not seem to exist anymore.
In case it matters, I work mostly with C++ files.
Update:
The only method that seems to allow me to cycle through autocompletions is C-c , space (semantic-complete-analyze-inline), where I can use TAB to autocomplete, but it doesn't show a menu of possible autocompletions that I can choose from.
In new versions of CEDET it's recommended to use auto-complete or similar packages. You can add ac-semantic to ac-sources, and then auto-complete will use Semantic as source of data for completions. The new version of Emacs/CEDET articles, mentions this setup & shows necessary code. Please try it

Text Zoom in putty emacs

I'm currently using Emacs 23.1 on a remote server through putty. I would like to be able to zoom out (so I can view all my code when needed). I've tried several methods and none of them have worked.
Text-scale-decrease and text-scale-increase give no errors but don't change the text size
The zoom-frm plugin tells me that "symbol's function definition is void: query-fontset" when I attempt to use any of its methods (all dependencies listed are installed)
The doremi-frm plugin either gives no errors and does nothing, or complains about face-remap (depending on what function is used)
I'm wondering at this point if zoom is possible within putty, and if so how do I get it to work properly.
P.S. Opening a remote X11 session with the Emacs GUI is not an option.
Thanks.
You need to config putty instead.
Open putty, then right click > Change Settings > Window > Fonts on the left panel to change font size.
What Emacs are you using? You say Emacs 23.1, but that has `query-fontset' (as do also older and more recent Emacs versions, from GNU Emacs 20 to the latest GNU Emacs 24 dev build).
Likewise, GNU Emacs 23.1 has face-remap' and all of its relatives,face-remap-*'.
I can't answer the putty questions, but can you check in some other way whether Emacs at the remote end actually zooms OK using any of the methods you describe? IOW, try to remove putty from the equation, to see what happens.

emacs gud window use

How do I customize which window GUD will use when i issue commands - 'up', 'down', etc ? It seems to use an arbitrary window, sometimes even the window with gdb in it - I want to be able to specify a specific window to be used.
Have you considered borrowing the key bindings mentioned in the following question?
Emacs, switch to previous window
This question implies that GUD steps on some things if you don't add a parameter. Maybe your command bindings are being affected similiarly.
Using gdb in Emacs 23
I asked a buddy of mine about this issue and here is what he said.
Well, we used xemacs and so it's not exactly apples to apples here. I
do have gnu-emacs installed on cygwin and I can't replicate his
problem. I think he definitely needs to list a version # for emacs
and the version # for all his installed packages.
When you press up/down it calls 'previous-line' and 'next-line'
respectively which both move the cursor in the default buffer. The
only thing I can think is that he has something running that switches
buffers (lisp 'set-buffer') temporarily and maybe doesn't set it back
or errors b/f restoring the buffer? Better to use
'with-current-buffer' (or one of the other with-* forms) that saves
the current state of the ui runs your lisp code and restores the ui
state.

Icons in dired mode for Emacs

I would like to use the dired mode of emacs as my file browser. I am very much addicted to see an icon for file/folder rather that to see the extension and color. The icons give me a very quick visual feedback. I have searched the web for display of icons in dired but found none. So I wonder whether it is even possible to do this and if yes how?
To put my question clearly
How can I display icons for files and folders in dired mode of Emacs?
all-the-icons-dired is a more current solution. Another option that looks quite nice is to use treemacs-icons-dired
I just switched to treemacs-icons-dired and recommend it. Simply install the package and add a mode hook like:
(add-hook 'dired-mode-hook 'treemacs-icons-dired-mode)
If you are using Windows, you can try dired-dispicon.el.
Get the relevant files from here.
See http://wiki.gohome.org/teranisi/?EmacsOnWindows for what it looks like. Note that you will probably need a version of emacs that supports images (e.g. for Windows you could try EmacsW32).
Use the dired-icon extension, which works for GTK (on Linux).
