There are a lot of function declarations in this initialization file. Most of them are not written by me, but many are edited. Only some of them are here. The main idea with function declarations is to defer them on start-up to save time. One way to do that is to put them in the :config section of a use-package declaration and defer that configuration via one of use-package's defer statements (like :command or :defer). I've yet to defer a lot of things in my initialization. I'll get to it at some point but it's not now in terms of time a priority. Keep that in mind if you use any of these functions in your init file.
Clear The Kill Ring
Pretty straight forward. Emacs keeps lots of goodies you copied on the clipboard. Later I'll show you how you can cycle through them. This bad boy clears everything when you no longer want to deal with the insanity.
;clear kill-ring
(defun clear-kill-ring ()
"Clear the kill ring variable"
(interactive)
(setq kill-ring nil
kill-ring-yank-pointer nil))
toggle-all-the-icons-dired-mode
You need All The Icons installed for this. See the link for images. All The Icons can be slow with large directories on windows, based on how well your system is optimized for memory. This let's you use it when you want to (for example when transferring files between directories or cleaning them up).
;toggle-all-the-icons-dired-mode
(defun toggle-all-the-icons-dired-mode ()
(interactive)
(if (featurep 'all-the-icons-dired)
(if all-the-icons-dired-mode
(progn
(setq all-the-icons-dired-mode nil)
(remove-hook 'dired-mode-hook 'all-the-icons-dired-mode ));end on case
(progn
(all-the-icons-dired-mode)
(add-hook 'dired-mode-hook 'all-the-icons-dired-mode ));end off case
);end conditional
);end package conditional
);end toggle-all-the-icons
Shell get buffer create
This is used by the function that follows it, "shell-same-window". It opens a shell in the buffer you are working in.
;shell in same window
(defun shell-get-buffer-create (&optional buffer)
"Run an inferior shell, with I/O through BUFFER (which defaults to `*shell*').
Interactively, a prefix arg means to prompt for BUFFER.
If `default-directory' is a remote file name, it is also prompted
to change if called with a prefix arg.
If BUFFER exists but shell process is not running, make new shell.
If BUFFER exists and shell process is running, just switch to BUFFER.
Program used comes from variable `explicit-shell-file-name',
or (if that is nil) from the ESHELL environment variable,
or (if that is nil) from `shell-file-name'.
If a file `~/.emacs_SHELLNAME' exists, or `~/.emacs.d/init_SHELLNAME.sh',
it is given as initial input (but this may be lost, due to a timing
error, if the shell discards input when it starts up).
The buffer is put in Shell mode, giving commands for sending input
and controlling the subjobs of the shell. See `shell-mode'.
See also the variable `shell-prompt-pattern'.
To specify a coding system for converting non-ASCII characters
in the input and output to the shell, use \\[universal-coding-system-argument]
before \\[shell]. You can also specify this with \\[set-buffer-process-coding-system]
in the shell buffer, after you start the shell.
The default comes from `process-coding-system-alist' and
`default-process-coding-system'.
The shell file name (sans directories) is used to make a symbol name
such as `explicit-csh-args'. If that symbol is a variable,
its value is used as a list of arguments when invoking the shell.
Otherwise, one argument `-i' is passed to the shell.
\(Type \\[describe-mode] in the shell buffer for a list of commands.)"

Open Shell In Same Window
Opens a shell in the window you are working.

Here are couple of mpd player functions.
The mpd player is the music player I use. You can stream music with it also. It's a command line tool you can read about here. MPD needs to be stopped and started from the shell. So there are a couple of windows scripts here that do that.
| |
And here are the script paths and scripts. VBS scripts can run without opening a shell window on the desktop, so those scripts reference the windows shell-scripts, which is one way to do it.
| |
| |
MPD player needs an emacs compatible interface and I use the Mingus Player for that. I'll post later the hydra I use to interface the mingus player functions. '
The rest of the functions in this init section support the Windows Program Launcher. Here's some code for that hydra.

So that's all for this section. Next are defaults and customizations. If you already have an emacs init you should be familiar with many of the upcoming defaults.
