#+TITLE: ryuslash's Emacs init
#+PROPERTY: tangle init2.el
#+STARTUP: showall
#+OPTIONS: author:nil num:nil toc:nil
#+MACRO: key @@html:<kbd>$1</kbd>@@@@ascii:`$1'@@
#+HTML_HEAD: <link href="https://ryuslash.org/org.css" rel="stylesheet" type="text/css">
* Cleanup basic UI
The tool-bar, menu-bar and scroll-bar aren't particularly
keyboard-friendly and just take up space if you don't use them.
Anything in the tool-bar or menu-bar can be accessed just as easily
with {{{key(M-x)}}}. The scroll-bar is almost just as informative as
the current line number and buffer position information.
#+BEGIN_SRC emacs-lisp :padline no
(menu-bar-mode -1)
(tool-bar-mode -1)
(scroll-bar-mode -1)
#+END_SRC
* Stop blinking!
Blinking cursors are a distraction.
#+BEGIN_SRC emacs-lisp
(blink-cursor-mode -1)
#+END_SRC
* Buffer position
As I'm currently using svg-mode-line-themes[fn:1] for my ~mode-line~ I
don't need to show these. Also I didn't really use them much, I
don't often need to know what line I'm on.
#+BEGIN_SRC emacs-lisp
(column-number-mode -1)
(line-number-mode -1)
#+END_SRC
* Don't show tooltips
Tooltips are another one of those UI elements that aren't quite
keyboard-friendly. As usually this information is shown just as well
in the echo area, this is not necessary.
#+BEGIN_SRC emacs-lisp
(tooltip-mode -1)
#+END_SRC
* Add org-mode appointments to the diary
Diary offers reminders, which can be useful when scheduling
appointments.
#+BEGIN_SRC emacs-lisp
(defadvice org-agenda-redo (after ext:org-agenda-redo-add-appts)
"Pressing `r' on the agenda will also add appointments."
(setq appt-time-msg-list nil)
(org-agenda-to-appt))
#+END_SRC
* Close ansi-term buffer after exit
After the ansi-term process ends it leaves a buffer. I don't use
ansi term in such a way that this has ever been useful, so just kill
the ansi-term buffer after the process quits, no matter the exit
status. Usually this comes about when I press {{{kbd(C-d)}}} at the
command prompt.
#+BEGIN_SRC emacs-lisp
(defadvice term-handle-exit (after oni:kill-buffer-after-exit activate)
"Kill the term buffer if the process finished."
(kill-buffer (current-buffer)))
#+END_SRC
* Stumpwm integration
This variable, macro and function help with integrating Emacs and
Stumpwm. They are used by several other functions to make the two
seem extra connected. An example of this can be found in [[Fall back
on stumpwm when moving around]].
#+BEGIN_SRC emacs-lisp
(defvar oni:stumpish-program
(expand-file-name
"~/.local/share/quicklisp/local-projects/stumpwm/contrib/util/stumpish/stumpish")
"The location of the stumpish executable.")
(defmacro oni:stumpwm (&rest body)
"Execute BODY in stumpwm."
(declare (indent 0))
`(call-process oni:stumpish-program nil nil nil
,(format "eval '%S'" `(progn ,@body))))
(defun oni:stumpwm-command (cmd)
"Execute CMD in stumpwm."
(call-process oni:stumpish-program nil nil nil cmd))
(defun oni:stumpwm-echo (message)
(call-process oni:stumpish-program nil nil nil (format "echo %s" message)))
#+END_SRC
* Fall back on stumpwm when moving around
Using the function specified in [[Stumpwm integration]] wrap the
=windmove-do-window-select= function and catch any error produced,
hoping it's the error that there's no more window to move to and
then request that stumpwm move the focus in the same direction as
windmove would have.
#+BEGIN_SRC emacs-lisp
(defadvice windmove-do-window-select
(around oni:windmove-stumpwm activate)
"If no window can be moved to, move stumpwm."
(condition-case err
ad-do-it
(error (oni:stumpwm-command
(format "move-focus %s" (ad-get-arg 0))))))
#+END_SRC
* Don't just quit Emacs with {{{key(C-x C-c)}}} in the daemon
When working with Emacs as a daemon, which I do almost all of the
time, I prefer using {{{key(C-x C-c)}}} to close the current frame
instead of the entire session. Before this change I would
occasionally close my session by mistake.
#+BEGIN_SRC emacs-lisp
(defun oni:close-client-window ()
"Close a client's frames."
(interactive)
(server-save-buffers-kill-terminal nil))
(when (daemonp)
(global-set-key (kbd "C-x C-c") 'oni:close-client-window))
#+END_SRC
* Don't minimize the frame with {{{key(C-z)}}}
One of the more annoying things that can happen is accidentally
minimizing the frame you're working with. This doesn't really matter
if you're working on a normal stacking window manager, but with a
tiling window manager and no task bar this just causes the Emacs
frame to hang until it is refocused or disappear with no way to get
it back.
#+BEGIN_SRC emacs-lisp
(when (or window-system (daemonp))
(global-unset-key (kbd "C-z")))
#+END_SRC
* Use the right dictionary
One of the caveats of using two (or more) languages in a single
installation of Gnus is that ispell sometimes gets confused. Having
come across a stackoverflow question[fn:2] about just this subject
it was easy to modify the source code posted there to come up with
this.
#+BEGIN_SRC emacs-lisp
(defun oni:switch-ispell-dictionary ()
(save-excursion
(message-narrow-to-headers-or-head)
(let ((from (message-fetch-field "From")))
(ispell-change-dictionary
(if (string-match (rx "@aethon.nl>" eol) from) "nl" "en")))))
(add-hook 'message-setup-hook 'oni:switch-ispell-dictionary)
#+END_SRC
* Don't let shr use background color
Reading mail in Gnus is very nice, but shr has become a little too
good at its job. Add to this the many occasions when a background is
specified without specifying a foreground, plus a color theme that
is the inverse of what is usually expected, and you can get
hard-to-read HTML messages, gray foreground and gray background.
I've looked at the other possible renderers, but they don't look
very nice compared to shr. So just remove its ability to add
background colors.
#+BEGIN_SRC emacs-lisp
(defun oni:shr-colorize-remove-last-arg (args)
"If ARGS has more than 3 items, remove the last one."
(if (> (length args) 3)
(butlast args)
args))
(with-eval-after-load 'shr
(advice-add #'shr-colorize-region :filter-args
#'oni:shr-colorize-remove-last-arg))
#+END_SRC
* Optimized ~with-eval-after-load~
First offered [[http://www.lunaryorn.com/2013/05/01/byte-compiling-eval-after-load.html][here]] and then later updated [[http://www.lunaryorn.com/2013/06/25/introducing-with-eval-after-load.html][here]] (when
~with-eval-after-load~ was added). Makes for very nice on-demand
settings loading.
#+BEGIN_SRC emacs-lisp
;; http://www.lunaryorn.com/2013/06/25/introducing-with-eval-after-load/
(defmacro stante-after (feature &rest forms)
"After FEATURE is loaded, evaluate FORMS.
FEATURE may be an unquoted feature symbol or a file name, see
`eval-after-load'."
(declare (indent 1) (debug t))
`(,(if (or (not byte-compile-current-file)
(if (symbolp feature)
(require feature nil :noerror)
(load feature :no-message :no-error)))
`progn
(message "stante-after: cannot find %s" feature)
'with-no-warnings)
(with-eval-after-load ',feature ,@forms)))
#+END_SRC
* Remember SQL input
Remembering input between sessions is a good thing.
#+BEGIN_SRC emacs-lisp
(stante-after sql
(setf sql-input-ring-file-name
(expand-file-name "~/.emacs.d/sqliinput")))
#+END_SRC
* Lazily load some buffers
Don't load all buffers right away. Having a lot of buffers and
switching between projects a lot can take up quite a bit of time.
#+BEGIN_SRC emacs-lisp
(setq desktop-restore-eager 5)
#+END_SRC
