Turn off useless visual components gui
Turn the menu, scroll-bar and tool-bar off quickly. If this happens later on then the GUI will show these components for a longer time. Even though these options are also specified in my Xdefaults I like having them here too, as a precaution and to turn them off for non-graphical interfaces as well.
(menu-bar-mode -1)
(scroll-bar-mode -1)
(tool-bar-mode -1)
Setup load-path load_path
Not everything can be installed with package.el
. Or some things can,
but I prefer installing them manually because it's easier. Anyway,
some additions should be made to load-path
and if the file
loaddefs.el
exists, load it for the autoloads.
(mapc #'(lambda (dir)
(add-to-list 'load-path dir)
(let ((loaddefs (concat dir "/loaddefs.el")))
(when (file-exists-p loaddefs)
(load loaddefs))))
'("~/.emacs.d/site-lisp" "~/projects/emacs/pony-mode/src"
"~/projects/emacs/php-mode" "~/.emacs.d/vendor-lisp/org/lisp"
"~/.emacs.d/vendor-lisp/org/contrib/lisp"))
Load other functions
Including all the functions being used here would make this file
immens and perhaps also somewhat unclear. In any case there are a
number of functions that I have found on the web in ext.el
, and a
number that I have written myself in oni.el
. So load them.
(require 'ext)
(require 'oni)
Load theme theme
I have been experimenting with my own color theme for quite a while
now. I use package.el
to install it, so to load it I need to wait
until after it has been loaded to enable it. Some of these settings
have also been specified in my Xdefaults so that it doesn't start
with a completely white background (for too long).
(setq custom-theme-directory "~/.emacs.d/themes")
(oni:eval-after-init (load-theme 'yoshi t))
Replace yes or no with y or n y_or_n_p
I have never had the trouble of accidentally pressing y
at the
moment Emacs wants to ask me something. And having to type yes <RET>
for a simple question gets in the way of things, so I prefer
y-or-n-p
.
(defalias 'yes-or-no-p 'y-or-n-p)
Replace list-buffers with ibuffer ibuffer
ibuffer
offers some excellent ways to manage buffers. One of which
is the function to filter the buffer list on (almost) any predicate,
including the buffer's mode. list-buffers
is simplistic compared to
this.
(defalias 'list-buffers 'ibuffer)
Replace dabbrev with hippie-expand hippie_expand
hippie-expand
has an expansion that functions the same as
dabbrev-expand
and it also has many more. I cannot think of a reason
why dabbrev-expand
should be used when hippie-expand
is also an
option.
(defalias 'dabbrev-expand 'hippie-expand)
Hide compilation window after success compilation
If compilation was succesfull I really don't need to see the
compilation window. So if either *Compilation*
or *compilation*
finishes correctly, delete the windows and show a message instead.
(defun ext:comp-finish-function (buf str)
"Close the compilation buffer quickly if everything went OK."
(if (string-match "exited abnormally" str)
;; there were errors
(message "compilation errors, press C-x ` to visit")
;; no errors, make the compilation window go away in 0.5 seconds
(when (member (buffer-name) '("*Compilation*" "*compilation*"))
(delete-windows-on buf)
(message "No compilation errors!"))))
(add-to-list 'compilation-finish-functions 'ext:comp-finish-function)
Scroll compilation window compilation
Even though I don't need to see the result of the compilation if everything went as it should, scroll the output window so that I can see whether there are any warnings and I should have a look anyway.
(setq compilation-scroll-output t)
Enable auto-fill-mode auto_fill
auto-fill-mode
automatically inserts newlines when a line becomes
too long. This is useful for both text modes and the comments in
programming modes. What it takes for a line to become too long is
specified by the fill-column
variable.
(add-hook 'prog-mode-hook 'auto-fill-mode)
(add-hook 'text-mode-hook 'auto-fill-mode)
Enable eldoc-mode eldoc
eldoc-mode
shows the arguments for the function call at point in the
minibuffer, or in the mode-line if you're in the minibuffer. This is
very useful when writing Emacs Lisp code.
(add-hook 'emacs-lisp-mode-hook 'eldoc-mode)
(add-hook 'ielm-mode-hook 'eldoc-mode)
Enable fill-column-indicator fill_column_indicator
Emacs has many packages that try to deal with showing a right
margin, the 80th column which your code should not go beyond. None
of these packages get it quite right, but fill-column-indicator
gets
pretty close.
(add-hook 'html-mode-hook 'fci-mode)
(add-hook 'prog-mode-hook 'fci-mode)
Enable flycheck-mode flycheck
Flycheck is a modern version of Flymake. They're not actually related, but Flycheck did come from the idea of Flymake. Flycheck has some interesting graphical elements (uses the fringe) and seems to have a pretty flexible way of creating new checkers. I enable it for all the modes that I use it supports.
(add-hook 'css-mode-hook 'flycheck-mode)
(add-hook 'emacs-lisp-mode-hook 'flycheck-mode)
(add-hook 'go-mode-hook 'flycheck-mode)
(add-hook 'html-mode-hook 'flycheck-mode)
(add-hook 'js2-mode-hook 'flycheck-mode)
(add-hook 'lua-mode-hook 'flycheck-mode)
(add-hook 'php-mode-hook 'flycheck-mode)
(add-hook 'python-mode-hook 'flycheck-mode)
(add-hook 'rst-mode-hook 'flycheck-mode)
(add-hook 'ruby-mode-hook 'flycheck-mode)
(add-hook 'rust-mode-hook 'flycheck-mode)
(add-hook 'sh-mode-hook 'flycheck-mode)
Enable flyspell-mode flyspell
What Flymake and Flycheck are to compilation, Flyspell is to
spelling. Runs spell checking in the background and highlights
spelling errors. It might be useful in programming mode comments,
but that seems a bit over the top for me, I care about the code, not
so much about the words used. So I only enable it in text-mode
.
(add-hook 'text-mode-hook 'flyspell-mode)
Enable paredit-mode paredit
I had long thought of paredit-mode
as overly complex and not very
useful. Though maybe I did try it out last before I started writing
so much Lisp code. In any case, I was wrong, it is one of the best
modes to use when editing Lisp and Lisp-like languages, changes your
whole perspective on the code.
(add-hook 'clojure-mode-hook 'paredit-mode)
(add-hook 'emacs-lisp-mode-hook 'paredit-mode)
(add-hook 'lisp-mode-hook 'paredit-mode)
(add-hook 'sawfish-mode-hook 'paredit-mode)
(add-hook 'scheme-mode-hook 'paredit-mode)
(add-hook 'ielm-mode-hook 'paredit-mode)
Enable rainbow-delimiters-mode rainbow_delimiters
Any language can have quite deeply nested "delimeters", meaning parentheses, brackets, curly braces. It helps to see their depth visually. Not just in Lisp.
(add-hook 'prog-mode-hook 'rainbow-delimiters-mode)
Enable rainbow-mode rainbow
When editing color-heavy "code", like CSS, it's useful to be able to
see color you're specifying. rainbow-mode
does this.
(add-hook 'css-mode-hook 'rainbow-mode)
Enable slime-js-minor-mode js2
SLIME is one of the coolest things about using Emacs to edit Lisp
code, so if there is something similar for JavaScript, even makes it
worth it to use the seemingly over-engineered js2-mode
.
(add-hook 'js2-mode-hook 'slime-js-minor-mode)
Enable smartparens-mode smartparens
smartparens-mode
is a less strict and less lisp-focused mode that
tries to do something similar to paredit-mode
. It is nice to use if
you're not writing in a Lisp-like language.
(add-hook 'html-mode-hook 'smartparens-mode)
(add-hook 'python-mode-hook 'smartparens-mode)
Enable visual-line-mode visual_line
Having words run off the screen in a chat session is unpleasant.
Having the words cut-off wherever the line ends is even worse! Use
visual-line-mode
to get some proper word wrapping behaviour in these
buffers.
(add-hook 'jabber-chat-mode-hook 'visual-line-mode)
(add-hook 'erc-mode-hook 'visual-line-mode)
Enable whitespace-mode whitespace
In most programming languages whitespace is pretty unimportant. As
long as the readers can stand it the compilers/interpreters usually
don't care. Of course this is not true for Python, and Markdown also
has special meanings for some whitespace in some places, so enabling
whitespace-mode
is a good idea, just for these two situations.
(add-hook 'markdown-mode-hook 'whitespace-mode)
(add-hook 'python-mode-hook 'whitespace-mode)
Enable yas-minor-mode yas
I still need to figure out where this mode comes in in my workflow.
I try to limit code-repetition as much as I can and anything that
does repeat often is so trivial that it doesn't benefit from
snippets. And using snippets for if
statements and such doesn't
strike me as terribly useful either. But perhaps I haven't seen the
magic of it yet. I do know that it is an interesting tool and I wish
to find a use for it at some point.
(add-hook 'html-mode-hook 'yas-minor-mode)
(add-hook 'org-mode-hook 'yas-minor-mode)
(add-hook 'prog-mode-hook 'yas-minor-mode)
Enable tagedit-mode tagedit
tagedit-mode
tries to be for XML/HTML what paredit-mode
is for Lisp.
And because of this, it rocks. It almost makes me feel sorry that I
don't write all that much XML or HTML nowadays. Enable the
experimental features as well, so it's really close to paredit-mode
.
(defun oni:turn-on-tagedit-mode ()
(require 'tagedit)
(tagedit-mode)
(tagedit-add-paredit-like-keybindings)
(tagedit-add-experimental-features))
(add-hook 'html-mode-hook 'oni:turn-on-tagedit-mode)
Disable the pylint and pyflakes checkers flycheck
I use flake8 in python-mode
, so I have no need for the python-pylint
and python-pyflakes
checkers. Since this works on a variable that is
defined in the flycheck
package, it should only run after flycheck
has been loaded.
(eval-after-load "flycheck"
'(progn
(mapc (lambda (c) (delq c flycheck-checkers))
'(python-pylint python-pyflakes))))
Make ^L look pretty ppcL
Occasionally I might put a ^L
character in some code to create a
page separator. But seeing ^L
there isn't all that pretty, not when
you have something like pp^L-mode
. Show a line of -
all the way to
the fill-column
- 1
. To do this we should also remove the prefix.
If the variable fci-rule-colum
is bound, use that, so that it
always goes up-to, but not beyond the little red line shown at the
right margin.
(defun oni:pretty-control-l-function (win)
"Just make a string of either `fci-rule-column' or
`fill-column' length -1. Use the `-' character. WIN is ignored."
(ignore win)
(make-string
(1- (if (boundp 'fci-rule-column) fci-rule-column fill-column)) ?-))
(setq pp^L-^L-string-function 'oni:pretty-control-l-function
pp^L-^L-string-pre nil)
This mode should be activated each time a frame is made, since it uses certain frame properties.
(add-hook 'emacs-startup-hook 'pretty-control-l-mode)
(add-hook 'after-make-frame-functions
'(lambda (arg) (pretty-control-l-mode)))
Auto-join some channels in ERC erc
If ever I log in to IRC with ERC I would like to join these channels, seeing as how if I talk, it's usually in one of these. Though it's rare.
(setq erc-autojoin-channels-alist
'(("freenode.net" "#ninthfloor" "#emacs" "#dispass")))
Don't show part messages in ERC erc
They don't interest me.
(setq erc-hide-list '("PART"))
I used to hide more messages, but I found out that it can be confusing to not be able to see any joins and quits at all.
Move the timestamp in ERC erc
I prefer having a timestamp on the left-side of a message in the
form of 00:00
instead of te usual. Having it right-aligned messes up
the non-filled text and having it only show up when it's changed
makes the buffer messy.
(setq erc-insert-timestamp-function 'erc-insert-timestamp-left
erc-timestamp-format "[%H:%M] "
erc-timestamp-only-if-changed-flag nil)
Set IRC nickname erc
This way I don't have to tell ERC what my nickname is every time.
(setq erc-nick "ryuslash")
Turn off filling in ERC erc
Turn of erc-fill-mode
so that visual-line-mode
can do its thing.
(defun oni:turn-off-erc-fill-mode () (erc-fill-mode -1))
(add-hook 'erc-mode-hook 'oni:turn-off-erc-fill-mode)
Specify some visual commands for eshell eshell
Eshell uses buffered input, always, but some commands need
unbuffered input, put those commands in eshell-visual-commands
to
have them open in a dedicated *term*
buffer. Since this variable is
defined in the em-term
module, it should only be changed after shis
module loads.
(eval-after-load "em-term"
'(add-to-list 'eshell-visual-commands "unison"))
Disable prompt highlighting in eshell eshell
Since I'm using a custom prompt with some custom colors I don't need the eshell prompt to be highlighted, which overwrites any colors I specify.
(setq eshell-highlight-prompt nil)
Customize eshell prompt eshell
Create a prompt that shows the following:
- The exit code of the previous command: a green
+
for exit code0
and a red-
for any non-zero exit code. - The hostname of the device running the current Emacs instance.
- An abbreviated indication of the current directory. To keep things
short this abbreviation is the first letter of each parent
directory and the full name of the current directory, still
separated by
/
, though. - Which branch (if any) the current directory has been checked-out of. This is not shown if the current directory is not a git directory.
(defun oni:eshell-prompt-function ()
"Show a pretty shell prompt."
(let ((status (if (zerop eshell-last-command-status) ?+ ?-))
(hostname (oni:hostname))
(dir (abbreviate-file-name (eshell/pwd)))
(branch
(shell-command-to-string
"git branch --contains HEAD 2>/dev/null | sed -e '/^[^*]/d'")))
(concat
(propertize (char-to-string status)
'face `(:foreground ,(if (= status ?+)
"green"
"red")))
" "
(propertize hostname 'face 'mode-line-buffer-id)

(propertize (oni:shorten-dir dir) 'face 'font-lock-string-face)
" "
(when (not (string= branch ""))
(propertize
;; Cut off "* " and "\n"
(substring branch 2 -1)
'face 'font-lock-function-name-face))
" \n> ")))
Set the prompt function to the function above and tell eshell the format of its prompt.
(setq eshell-prompt-function 'oni:eshell-prompt-function
eshell-prompt-regexp "^> ")
Add a pop-up function for eshell eshell
When working I often need to switch to a shell to issue some quick
commands and then be on my merry way again, to help with this I have
added a function which tries to move the current working directory
to that of the file being worked on and shows eshell. I bind this
function to f8
for easy access.
(defun oni:raise-eshell ()
"Start or switch back to `eshell'.
Also change directories to current working directory."
(interactive)
(let ((dir (file-name-directory
(or (buffer-file-name) "~/")))
(hasfile (not (eq (buffer-file-name) nil)))
(started (and (boundp 'eshell-buffer-name) eshell-buffer-name
(buffer-live-p (get-buffer eshell-buffer-name)))))
(eshell)
(when (and hasfile (eq eshell-process-list nil))
(eshell/cd dir)
(when started
(eshell-reset)))))
(global-set-key (kbd "<f8>") 'oni:raise-eshell)
Disable undo in eshell buffers eshell
Eshell buffers can get big and undo does not serve any real purpose in these buffers. Instead of getting boundary limit popups all the time, which I do want to keep for other buffers, it's easier to just turn off undo information for such buffers.
(add-hook 'eshell-mode-hook 'buffer-disable-undo)
Disable bidirectional support bidi
Since I don't ever get any mail from people that use right-to-left text, and even if I did I wouldn't be able to read it, I don't need bidirectional text support. You shouldn't actually disable it (if that's even still possible) since, supposedly, it is an integral part of the display engine now, but telling it to always use left-to-right should keep it from slowing your emacs down.
(setq-default bidi-paragraph-direction 'left-to-right)
Enable some "advanced" functions
These functions are disabled by default, because beginners find them confusing, apparently. Though I won't say I'm an Emacs master or guru, I can say that I'm not a beginner, and these functions have not confused me yet. So enable them.
(put 'downcase-region 'disabled nil)
(put 'narrow-to-page 'disabled nil)
(put 'narrow-to-region 'disabled nil)
(put 'scroll-left 'disabled nil)
(put 'upcase-region 'disabled nil)
Don't echo status changes for jabber jabber
If I'm talking to someone I'll see their status and if they're
offline and I want to say something I can say it anyway, I don't
need constant updates in my echo-area on the status of my jabber
buddies. But since this relies on something from the jabber
module,
only run it after that module has been loaded.
(eval-after-load "jabber"
'(remove-hook 'jabber-alert-presence-hooks 'jabber-presence-echo))
Use libnotify for jabber notifications jabber
The functions don't seem to be loaded automatically, so add autoloads for the libnotify functions.
(autoload 'jabber-message-libnotify "jabber-libnotify")
(autoload 'jabber-muc-libnotify "jabber-libnotify")
(add-hook 'jabber-alert-message-hooks 'jabber-message-libnotify)
(add-hook 'jabber-alert-muc-hooks 'jabber-muc-libnotify)
Enable history jabber
Enable chat history for both regular chats and multi-user chats. I
disabled history completely for a long time, but sometimes you miss
things that way. Store history in per-contact files under
HOME/.emacs.d/jabber-hist
.
(setq jabber-history-enabled t
jabber-history-muc-enabled t
jabber-use-global-history nil
jabber-history-dir "~/.emacs.d/jabber-hist")
Setup accounts for jabber jabber
Each account should have the current hostname appended to its account name, so that multiple PCs can log in on the same account at the same time and it's easy to note from where I'm talking.
(setq jabber-account-list `((,(concat "tom@ryuslash.org/" (oni:hostname))
(:connection-type . ssl))))
Have ido ignore certain buffers ido
These buffers are either uninteresting, reached through other means (such as a special keybinding) or they get in the way of how I work. For any or all of these reasons I wish to ignore them.
-
^\\`\s
- Any buffers that start with a space should be ignored.
-
^irc\\.
- Any buffer that starts with
irc.
is a buffer that has informational messages on the irc server I'm connected to, these don't change often and have other ways of grabbing my attention. If I need them I will find them. -
^\\#
- Any buffer starting with an
#
is most-likely an IRC chat buffer, these have ways of letting me know it there is anything interesting going on there, I don't usually need them clogging up my ido. -
^\\*Customize Option:
- Anything starting with
*Customize Option:
is part of Emacs's customize interface and thus doesn't need to be shown in the ido buffer list. -
*-jabber-roster-*
- Is also accessible through
f6
, so no need for it in my ido list. -
*Messages*
- Also accessible through
C-h e
, so no need for it. -
*fsm-debug*
- A buffer used by
jabber.el
to track some debug information, I have never had to look at it yet. -
*magit-process*
- The buffer where magit's git process runs,
usually accessible with
$
from any magit buffer, and the only other time I need to find is if I have to kill it to reset magit's process. -
*magit-edit-log*
- The commit message buffer from magit. Usually
accessible with
C-c c
if needed. -
*Backtrace*
- Usually only interesting for as long as I'm looking at it, if I bury it, I usually don't need it anymore.
-
*Ibuffer*
- is reached by the key compination
C-x C-b
, is therefore not needed to show up when using ido, and even gets glitchy when using ido, because the information doesn't get updated.
Since this requires a variable defined in the ido
module, delay
execution until it is loaded.
(defun oni:ido-init ()
"Initialization functionn for ido."
(setq ido-ignore-buffers
(list "^\\` " "^irc\\." "^\\#" "^\\*Customize Option:"

(eval-after-load "ido" '(oni:ido-init))
Disable automatic merging in ido ido
ido has this wonderful/infuriating feature of trying to correct your mistakes by suggesting files in other directories if it can't find the file you wish to open in the current directory. This becomes bothersome especially when working with django, since the same files tend to show up in several directories. Disable it.
According to the docstring this should be a way to disable it,
previously I just used a very long timeout by setting
ido-auto-merge-delay-time
to 1000000
.
(setq ido-auto-merge-work-directories-length -1)
Instruct ido to open buffers in selected window ido
By default, when more than one frame exists and you try to switch to a buffer that is already visible in another frame, ido pops up the other frame. This is not what I want, just open the buffer in the selected window no matter what.
(setq ido-default-buffer-method 'selected-window)
Minimize maximum minibuffer height for ido ido
I hate it when the minibuffer gets bigger than one line, so don't let ido do that.
(setq ido-max-window-height 1)
Don't save history for ido ido
I don't see the point in saving that history.
(setq ido-save-directory-list-file nil)
Turn on ido-mode ido
ido-mode
is an excellent file and buffer selection tool, it
improves upon regular selection in numerous ways.
(ido-mode)
Exclude functions from ido-ubiquitous ido_ubiquitous
Not all functions work well with ido-ubiquitous-mode
, like
org-refile
, so exclude them from using ido-ubiquitous-mode
.
(setq ido-ubiquitous-command-exceptions '(org-refile org-capture-refile))
Enable ido-ubiquitous-mode ido_ubiquitous
ido-ubiquitous-mode
lets you use ido for almost anything! Anything
which looks and acts like file or buffer selection anyway.
Since it is installed with ELPA, wait until after emacs has been initialized.
(add-hook 'emacs-startup-hook 'ido-ubiquitous-mode)
Enable idomenu idomenu
Imenu is an awesome feature, but since I don't use any menus it is
a little lost on me. idomenu
uses Imenu, but shows it in an
ido-like way, which works perfectly. Bind it to M-n
.
(global-set-key (kbd "M-n") 'idomenu)
Use electric default in minibuffer minibuffer
The minibuffer-electric-default-mode
hides the default value if you
start typing. This leaves more room for typing. I also want the
"short" default indicator ([default]
instead of (default: default)
).
(setq minibuffer-eldef-shorten-default t)
(minibuffer-electric-default-mode)
Don't show help message on empty parts mode_line
When hovering the mouse over empty parts of the mode-line, just show
nothing, don't clutter up my echo area and *Messages*
buffer.
(setq mode-line-default-help-echo "")
Enable jedi jedi
jedi is an interesting auto-completion program for the Python
programming language. On archlinux the program you usually want to
use is python2
, so change the jedi:server-command
accordingly and
run jedi:setup
when python-mode
starts to enable it.
(eval-after-load "jedi" '(setcar jedi:server-command "python2"))
(add-hook 'python-mode-hook 'jedi:setup)
Don't use a tooltip jedi
The coolest thing about jedi is its eldoc-like argument display. If it can figure out what the arguments are they're shown. But please don't use tooltips, just the echo area.
(setq jedi:tooltip-method nil)
Org initialization org
Since my intialization for org-mode

Close term buffer after exit term
When quitting the process in a term buffer, in other words, when quitting the shell, kill the buffer. Killing the shell, but not killing the buffer is a pain, it keeps you from quickly starting a term and quickly closing it too. This advice should be disabled if ever the shell crashes, because it doesn't look at the exit code, since the standard exit code is that of the last run command.
(defadvice term-handle-exit (after oni:kill-buffer-after-exit activate)
"Kill the term buffer if the process finished."
(kill-buffer (current-buffer)))
Changing case
I have no capslock key, and holding shift whilst typing big words
is annoying, so I wrote a couple of functions to help with that and
bind them to C-c u
and C-c d
.
(global-set-key (kbd "C-c u") 'oni:upcase-prev)
(global-set-key (kbd "C-c d") 'oni:downcase-prev)
Turn off usage of tabs for vala-mode vala
Somehow vala-mode
thinks it's ok for it to decide that it's users
should always use tabs. As far as I'm aware the vala compiler has
no such restriction, so turn it off.
(add-hook 'vala-mode-hook 'oni:vala-mode-func)
Use smex smex
Smex is to command selection what ido is to file selection. Very similar too, it was written with ido specifically in mind.
(global-set-key (kbd "M-x") 'smex)
(global-set-key (kbd "C-M-x") 'smex-major-mode-commands)
Autoload define-slime-contrib js2
slime-js-minor-mode
uses this function but forgets to require its
module, so I set up an autoload function for when I need it and
haven't yet used slime.
(autoload 'define-slime-contrib "slime")
Autoload some other functions
These need to have autoloads specified for various reasons, mostly because they're installed manually or because they're old.

Uniquify buffers better uniquify
The default way to make sure buffer names are unique is rather
uninformative, uniquify
has a few better options.
(require 'uniquify)
Use 4 spaces per indentation level
Often I see 8 being used, but that just seems too wide to me.
(setq-default c-basic-offset 4
tab-width 4)
Place fill-column-indicator fill_column_indicator
Place the ruler one character farther than what I usually prefer to have my lines wrap to, this will indicate where it should not cross, not where it should not continue.
(setq-default fci-rule-column 73)
Disable use of tabs
By default, use spaces, not tabs. Tabs are madness.
(setq-default indent-tabs-mode nil)
Don't warn about mumamo php
I haven't yet seen a mode that offers good multiple major modes support. And so I don't use any, so don't warn me that I don't.
(setq-default php-mode-warn-if-mumamo-off nil)
Ensure a final newline
When looking at diffs, it can be annoying to have 2 extra line
changes, just because te previous last line suddenly gets a newline
and the new one doesn't. Plus it's very uniform to have a \n
at the
end of every line.
(setq-default require-final-newline t)
Truncate lines
Just let most line run off the screen. I don't like wrapping my code around. I shouldn't make my lines too long in the first place, but in case I have a very small window I prefer the lines to remain unchanged, visually.
(setq-default truncate-lines t)
Send appointments to jabber jabber
When an appointment is coming up, show me in a buffer, but also send a message to my jabber account.
(setq appt-disp-window-function #'oni:appt-display-window-and-jabber)
Don't display diary when appt is initialized appt
If the diary is displayed after the initialization of appt
I would
get a diary buffer each time I load org-mode
. Since I don't use the
diary, except for what org-mode
puts in there for notifications and
such, I really don't want to see it, ever.
(setq appt-display-diary nil)
Don't case fold with auto modes
I haven't had to deal with wrongly-cased filenames since I stopped using windows.
(setq auto-mode-case-fold nil)
Save all auto saves in /tmp
Having auto save files everywhere cloggs up the filesystem. Move
them all into /tmp
, though I should probably use a less volatile
location.
(setq auto-save-file-name-transforms
`((".*" "~/.local/share/emacs/autosave/" t)))
Save all backup files to /tmp
Having backuf files everywhere also cloggs up the filesystem. Move
them all into /tmp
as well, though here too I should probably use a
less volatile location.
(setq backup-directory-alist `((".*" . "~/.local/share/emacs/backup/")))
Automatically determine browser browse
Use the BROWSER
environment variable to figure out which browser to
call for browse-url
. And use the browse-url-generic
function to open
urls, otherwise this setting would have no meaning.
(setq browse-url-browser-function 'browse-url-generic
browse-url-generic-program (getenv "BROWSER"))
Customize C indentation c
When writing C code, when calling a function I prefer the indentation to look like:
call_some_function(
argument1,
argument2
);
To be able to shorten lines with long function calls. As opposed to the default:
call_some_function(
argument1,
argument2,
);
Which doesn't really help in making lines shorter. And I also happen to think it looks hideous.
(setq c-offsets-alist
'((statement-block-intro . +)
(knr-argdecl-intro . 5)
(substatement-open . +)
(substatement-label . 0)
(label . 0)
(statement-case-open . +)
(statement-cont . +)
(arglist-intro . +)
(arglist-close . 0)
(inline-open . 0)
(brace-list-open . +)
(topmost-intro-cont first c-lineup-topmost-intro-cont
c-lineup-gnu-DEFUN-intro-cont)))
Move customize settings into their own file custom
Any settings I change using the customize interface should go into
a separate file. My init.el
is under version control and I don't
want each local change made in this way to be recorded in the VCS.
Plus the code generated by customize is an eyesore.
(setq custom-file "~/.emacs.d/custom.el")
Setup some frame parameters
Disable borders, disable scroll-bars, tool-bars and menu-bars (this is the third place I'm doing this, I really want them gone, don't I). And set the preferred font.
(setq default-frame-alist
`((border-width . 0)
(internal-border-width . 0)
(vertical-scroll-bars . nil)
(menu-bar-lines . nil)
(tool-bar-lines . nil)
(font . "Inconsolata:pixelsize=18")))
Stop elnode from running automatically elnode
I like elnode, but it really should stop starting itself up every time I start emacs. Not only can this cause problems with trying to run on the same port, but also this starts running programs that I have no idea of, whatever I was testing last.
(setq elnode-do-init nil)
Mention the buffer in the frame title
Having 5 Emacs frames all named "emacs" doesn't help to identify them, so add the opened buffer name to the title.
(setq frame-title-format '(:eval (concat "emacs: " (buffer-name))))
Store geiser history under .emacs.d
Everything Emacs related should be stored under HOME/.emacs.d
so as
not to fill my home directory with a bunch of directories.
(setq geiser-repl-history-filename "~/.emacs.d/geiser-history")
Change gnus init file
My gnus init file is separate, since I don't always immediately use gnus.
(setq gnus-init-file "~/.emacs.d/gnus")
Automatically update gtags TAGS gtags
Before there was this option I had some complicated function to do the same thing from somewhere, now that isn't necessary anymore.
(setq gtags-auto-update t)
Display help-at-point
When the cursor is in a location where a help message would be shown by hovering the mouse over it, show that help after a short time of idling on that spot. Another step in using no mouse whatsoever without losing any functionality.
(setq help-at-pt-display-when-idle t)
Set inferior lisp program to SBCL lisp
SBCL seems like a very good Lisp implementation to use, widely
supported by packagers too. --noinform
keeps the copyright message
from showing up and --no-linedit
is used by the linedit
package to
determine that it shouldn't be enabled.
(setq inferior-lisp-program "sbcl --noinform --no-linedit")
Inhibit stuff
I don't need to see the startup message, I don't want the default
init messing with my own stuff and I don't even know what
inhibit-local-menu-bar-menus
does, but it doesn't sound like I need
is, since I don't use menu bars.
(setq inhibit-default-init t
inhibit-local-menu-bar-menus t
inhibit-startup-message t)
Change the initial major mode and message
The lisp-interaction-mode
is a nice idea on paper, but usually when
I want to use the *scratch*
buffer, it just gets in my way, so use
emacs-lisp-mode
instead. Also, by now I know what the *scratch*
buffer is for, so I really don't need that message telling me what
it does.
(setq initial-major-mode 'emacs-lisp-mode
initial-scratch-message nil)
Store jabber avatar cache under .emacs.d jabber
Even though I don't use avatars anymore I don't want jabber.el
creating directories all over the place, so just to be safe I put
it under HOME/.emacs.d
.
(setq jabber-avatar-cache-directory "~/.emacs.d/jabber-avatars/")
Setup formats jabber
Most of the time I prefer having my message start at the beginning of the line, in case someone sends me a piece of code or I send them some, it's easier to read if you don't have to change it first.
But that leaves a lot of empty space on that prompt line, best fill it up as mucha as is still useful.
Also show the chat buffer names as just the contact's name prefixed
with a +
to keep them short and clean.
(setq jabber-chat-buffer-format "+%n"
jabber-chat-foreign-prompt-format "%t %u/%r <\n"
jabber-chat-local-prompt-format "%t %u/%r >\n"
jabber-groupchat-buffer-format "++%n"
jabber-groupchat-prompt-format "%t %u --\n")
Don't use avatars jabber
I did for a while, but since there is no concensus over what is good and what is bad, buffers start looking messy, so I just disabled them completely. I know most of the people I chat with personally, so it doesn't really add much anyway.
(setq jabber-chat-buffer-show-avatar nil
jabber-vcard-avatars-publish nil
jabber-vcard-avatars-retrieve nil)
Don't fill jabber
Just like ERC, don't fill lines so that visual-line-mode
can do
its thing.
(setq jabber-chat-fill-long-lines nil)
Don't send chatstates jabber
Don't let people know what I'm doing, don't send them information on that I'm typing or not, etc. This isn't very useful and it sometimes creates confusion when I accidentally start typing in the wrong buffer.
(setq jabber-chatstates-confirm nil)
Autojoin some channels jabber
Just one, really, the only one I'm in.
(setq jabber-muc-autojoin '("aethon@muc.ryuslash.org"))
Keep the roster buffer clean jabber
Most of the time I really don't need to see the keybindings for the roster buffers, so hide them initially. And the offline contacts as well.
(setq jabber-roster-show-bindings nil)
(setq jabber-show-offline-contacts nil)
Defer font locking a little fontlock
By deferring font-lock for a very short time it should improve scrolling performance.
(setq jit-lock-defer-time 0.2)
Turn on compilation-shell-minor-mode for pony buffers pony
Turn on compilation-shell-minor-mode
whenever pony-minor-mode
starts
in a comint-mode
buffer. Since buffers like *ponymanage*
and
*ponyserver*
don't have their own specialized modes, but use
comint-mode
and turn on pony-minor-mode
, and I don't want to enable
compilation-shell-minor-mode
for every comint-mode
buffer, we can
add a hook that adds a local hook.
I use compilation-shell-minor-mode
because some pony mode buffers
are interactive, such as the pony-shell buffer.
(defun turn-on-compilation-shell-for-pony ()
(add-hook 'pony-minor-mode-hook 'compilation-shell-minor-mode nil t))
(add-hook 'comint-mode-hook 'turn-on-compilation-shell-for-pony)
Make smartparens a little stricter smartparens
Set the delete and backspace keys to some smartparens keybindings that should make pair balancing a little stricter. These key bindings refuse to delete pair delimeters or skip over them if they still have content.
(defun oni:smartparens-set-keys ()
(local-set-key (kbd "DEL") 'sp-backward-delete-char)
(local-set-key (kbd "<deletechar>") 'sp-delete-char)
(local-set-key (kbd "C-d") 'sp-delete-char))
(add-hook 'smartparens-mode-on-hook 'oni:smartparens-set-keys)
Initialize EMMS emms
Initialize a minimal EMMS setup. Load the default players so we can use mplayer or any of the generic mp3 and ogg players.
Load the MPD player so we can connect to MPD and use that if possible, set the music directory to MPD's music directory so it knows how to translate filenames to something MPD understands.
Load the emms-mode-line
module so we can display some information in
the mode-line about which song is playing and set my preferred
function for extracting this information. The emms-info-mpd
function
doesn't seem to return anything, so I've had to improvise to turn
absolute file names into something nicer.
