#+TITLE: Emacs Configuration
* Literate emacs configuration
I can never rembember what various configs do. Jumping on this literate emacs
config to see if it helps!
** Set some ENV vars
These are needed to make emacs aware of various things (like Go binaries,
etc). I have them here because sometimes when emacs is launched from ~rofi~
or similar it doesn't have the same ENV as it does when launching from the
shell.
#+begin_src emacs-lisp
(defun expand-if-exists (d)
;; expand-if-exists(d) expands d only if d exists
(if (file-exists-p d)
(expand-file-name d)))
(let ((paths
'(
"/usr/local/bin"
"/usr/local/go/bin"
"/usr/local/MacGPG2/bin"
"/Library/TeX/texbin"
"/usr/local/jdk-11/bin"
"/usr/ports/infrastructure/bin"
"~/bin"
"~/.nix-profile/bin"
"~/go/bin"
"~/opt/bin"
"/usr/local/plan9/bin"
)))
(setenv "PATH" (concat (getenv "PATH") (mapconcat 'expand-if-exists (remove nil paths) ":")))
(setq exec-path (append exec-path (remove "" (split-string (getenv "PATH") ":")))))
#+end_src
** Start the emacs server
Starting as a server lets me connect externally to do things like change
themes, save buffers via cron and other such dumbary!
#+begin_src emacs-lisp
(load "server")
(unless (server-running-p) (server-start))
#+end_src
** OpenBSD Lockups
For some reason OpenBSD hangs, these seem to help a bit
#+begin_src emacs-lisp
(setq x-select-enable-clipboard-manager nil)
(setq x-select-request-type '(UTF8_STRING COMPOUND_TEXT TEXT STRING))
(setf x-selection-timeout 500)
#+end_src
** Interface and Behavior
*** Interface
Global font
#+begin_src emacs-lisp
;; This is currently set in ~/.Xresources - for some reason emacs doesn't like the line below
2022-09-05 08:09:45 -06:00
(set-frame-font "Go Mono")
2022-08-25 12:21:35 -06:00
#+end_src
Use 80 columns, this helps keep things readable when windows are split
#+begin_src emacs-lisp
(setq whitespace-style '(trailing lines space-before-tab)
whitespace-line-column 80)
(setq-default fill-column 80)
#+end_src
I know I am in emacs, don't need to see the startup screen.
#+begin_src emacs-lisp
(setq inhibit-startup-screen t)
#+end_src
If we are on OpenBSD, fill the scratch buffer with fortune \o/.
#+begin_src emacs-lisp
(if (file-executable-p "/usr/games/fortune")
(setq initial-scratch-message
(concat
(shell-command-to-string "fortune | sed -e 's/^/;; /g'")
"\n\n")))
#+end_src
**** Use UTF8 where ever possible
#+begin_src emacs-lisp
(prefer-coding-system 'utf-8)
(set-default-coding-systems 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
#+end_src
**** Change various UI bits
#+begin_src emacs-lisp
(tool-bar-mode -1)
(menu-bar-mode -1)
(scroll-bar-mode -1)
(column-number-mode +1)
(global-font-lock-mode 1)
#+end_src
**** No GNU ls here
#+begin_src emacs-lisp
(setq ls-lisp-use-insert-directory-program nil)
(require 'ls-lisp)
#+end_src
*** Behavior
Switch various defaults to be more comfortable for myself.
#+begin_src emacs-lisp
(fset 'yes-or-no-p 'y-or-n-p)
(show-paren-mode t)
(setq desktop-dirname "~/.emacs.d/"

desktop-save t

(setq backup-directory-alist '(("." . "~/.emacs-saves")))
(setq auto-mode-alist
(append

(setq auth-sources

#+end_src
Use spelling and auto-fill when we are in text mode.
#+begin_src emacs-lisp
(add-hook 'text-mode-hook (lambda ()
(auto-fill-mode 1)
(turn-on-flyspell)))
#+end_src
This fixes some tramp "waiting for prompt" errors.
#+begin_src emacs-lisp
;;(setq trarmp-shell-prompt-pattern "\\(?:^\\|\r\\)[^]#$%>λ\n]*#?[]#$%>λ].* *\\(^[\\[[0-9;]*[a-zA-Z] *\\)*")

#+end_src
If things _aren't_ working the way we want:
#+begin_src emacs-lisp
(setq tramp-verbose 6)
#+end_src
** Include ports site-lisp
On OpenBSD various packages (mu, git.. etc) install elisp things into a global
directory, this makes sure we include it.
#+begin_src emacs-lisp
(if (file-directory-p "/usr/local/share/emacs/site-lisp")
(add-to-list 'load-path "/usr/local/share/emacs/site-lisp/"))
#+end_src
** Unset custom-file
The customization file mostly just causes churn in the SCM so we disable it
here.
#+begin_src emacs-lisp
(setq custom-file (make-temp-file ""))
#+end_src
** Ensure packages are pinned and installed
This makes sure ~use-package~ installs things (and makes it so we don't need
~:ensure t~ set for every package.
#+begin_src emacs-lisp
(setq use-package-always-ensure t)
;;(setq use-package-always-pin "melpa-stable")
#+end_src
* Packages
** parchment-theme
This is a nice theme that resembles acme in plan9. Minimal.
#+begin_src emacs-lisp
(use-package parchment-theme
:config (load-theme 'parchment t))
#+end_src
** keychain-environment
I make heavy use of ~ssh-agent~ this lets emacs pickup / use the existing
agents I have running.
#+begin_src emacs-lisp
(use-package keychain-environment
;;:pin "melpa"
:init
(keychain-refresh-environment))
#+end_src
** ivy
~ivy~ is fantastic. It gives me nice visual search for buffers,
code.. etc. Combined with ~smex~ for sorting (shows last used things first) and
~counsel~ (extends ivy into various areas like the help stuff).
#+begin_src emacs-lisp
(use-package counsel)
(setq smex-save-file (expand-file-name "~/.emacs.d/smex.save"))
(use-package smex)
(use-package ivy
:hook (after-init . ivy-mode)
:bind
("C-s" . swiper)
("M-x" . counsel-M-x)
("C-x C-f" . counsel-find-file)
("C-x b" . ivy-switch-buffer))
#+end_src
** magit
Magit is a awesome. Not sure what else to say about it. :P
#+begin_src emacs-lisp
(use-package magit
:bind ("C-c m" . magit-status)
:init
(setq magit-completing-read-function 'ivy-completing-read))
#+end_src
** flycheck
~flycheck~ does automatic syntax checking for most things
#+begin_src emacs-lisp
(use-package flycheck
:init (global-flycheck-mode))
#+end_src
- [2020-05-29 Fri] Unfortunately it clobbers the "C-c !" prefix, so we need
to add this to get it back:
#+begin_src emacs-lisp
(define-key flycheck-mode-map (kbd "C-c !") 'org-time-stamp-inactive)
#+end_src
** lsp-mode
~lsp-mode~ supports language servers for various things. I pretty much only
care about Go and Ruby.
#+begin_src emacs-lisp
(use-package lsp-mode
:hook ((go-mode . lsp-deferred)
(ruby-mode . lsp))
:commands (lsp lsp-deferred))
#+end_src
** company and friends
~company~ allows for auto-completion of various things. It can interface with ~lsp-mode~ to complete
things like Go.
#+begin_src emacs-lisp
(use-package company
:config
(setq company-tooltip-limit 20
company-minimum-prefix-length 1
company-idle-delay .3
company-echo-delay 0)
:hook (prog-mode . company-mode))
#+end_src
** gitgutter
This gives me a nice in-ui way to see modifications and what not.
#+begin_src emacs-lisp
(use-package git-gutter
:hook
(after-init . global-git-gutter-mode))
#+end_src
** nix
Add support for nix files. I don't use nix much atm, but it was recently
ported to OpenBSD, so I am hopeful I can start using it there more!
#+begin_src emacs-lisp
(use-package nix-mode
:mode "\\.nix\\'")
#+end_src
** shell
I don't often use the shell from emacs, but when I do these bits make it
easier for me to treat it like a regular shell.
#+begin_src emacs-lisp
;; Kill terminal buffers on exit so I din't have to kill the buffer after I exit.
(defadvice term-handle-exit
(after term-kill-buffer-on-exit activate)
(kill-buffer))
#+end_src
** pinboard
A pinboard.in client
#+begin_src emacs-lisp
(use-package pinboard)
#+end_src
** restclient
#+begin_src emacs-lisp
(use-package restclient
;;:pin "melpa"
:mode (("\\.http$" . restclient-mode)))
#+end_src
** sr-speedbar
Speedbar is almost perfect.. If it only ran in the current frame!! :D
**** Enter sr-speedbar
#+begin_src emacs-lisp

;;; Commentary:
;;
;; The sr-speedbar.el was created just because I could not believe what I
;; read on http://www.emacswiki.org/cgi-bin/wiki/Speedbar. They wrote there
;; that it is not possible to show the speedbar in the same frame. But, as
;; we all know, ecb had this already. So I started as some kind of joke :)
;; But when I found it useful and use it all the time.
;;
;; Now you type windows key with 's' (`s-s' in Emacs) will show the speedbar
;; in an extra window, same frame. You can customize the initial width of the
;; speedbar window.
;;
;; Below are commands you can use:
;;
;; `sr-speedbar-open' Open `sr-speedbar' window.
;; `sr-speedbar-close' Close `sr-speedbar' window.
;; `sr-speedbar-toggle' Toggle `sr-speedbar' window.
;; `sr-speedbar-select-window' Select `sr-speedbar' window.
;; `sr-speedbar-refresh-turn-on' Turn on refresh speedbar content.
;; `sr-speedbar-refresh-turn-off' Turn off refresh speedbar content.
;; `sr-speedbar-refresh-toggle' Toggle refresh speedbar content.
;;
;; Enjoy! ;)
;;
;;; Installation:
;;
;; Copy sr-speedbar.el to your load-path and add to your ~/.emacs
;;
;; (require 'sr-speedbar)
;; (global-set-key (kbd "s-s") 'sr-speedbar-toggle)
;;
;; ... or any key binding you like.
;;
;;; Customize:
;;
;; M-x customize-group RET sr-speedbar RET
