If this happens later on then the GUI will show these components for a longer time.

So load them. #+BEGIN_SRC emacs-lisp (require 'ext) (require 'oni) #+END_SRC * 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 [[file:../.Xdefaults][Xdefaults]] so that it doesn't start with a completely white background (for too long). #+BEGIN_SRC emacs-lisp (setq custom-theme-directory "~/.emacs.d/themes") (oni:eval-after-init (load-theme 'yoshi t)) #+END_SRC * 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.

This is useful for both text modes and the comments in programming modes.

They're not actually related, but Flycheck did come from the idea of Flymake.

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=. #+BEGIN_SRC emacs-lisp (add-hook 'text-mode-hook 'flyspell-mode) #+END_SRC * 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.

It helps to see their depth visually. Not just in Lisp. #+BEGIN_SRC emacs-lisp (add-hook 'prog-mode-hook 'rainbow-delimiters-mode) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (add-hook 'css-mode-hook 'rainbow-mode) #+END_SRC * 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=. #+BEGIN_SRC emacs-lisp (add-hook 'js2-mode-hook 'slime-js-minor-mode) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (add-hook 'html-mode-hook 'smartparens-mode) (add-hook 'python-mode-hook 'smartparens-mode) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (add-hook 'jabber-chat-mode-hook 'visual-line-mode) (add-hook 'erc-mode-hook 'visual-line-mode) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (add-hook 'markdown-mode-hook 'whitespace-mode) (add-hook 'python-mode-hook 'whitespace-mode) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (add-hook 'html-mode-hook 'yas-minor-mode) (add-hook 'org-mode-hook 'yas-minor-mode) (add-hook 'prog-mode-hook 'yas-minor-mode) #+END_SRC * Enable tagedit-mode :tagedit: =tagedit-mode= tries to be for XML/HTML what =paredit-mode= is for Lisp.

Enable the experimental features as well, so it's really close to =paredit-mode=. #+BEGIN_SRC emacs-lisp (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) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (eval-after-load "flycheck" '(progn (mapc (lambda (c) (delq c flycheck-checkers)) '(python-pylint python-pyflakes)))) #+END_SRC * 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. #+BEGIN_SRC emacs-lisp (defun oni:pretty-control-l-function (win) "Just make a string of either `fci-rule-column' or `fill-column' length -1.
