suragu's Emacs config

This is my Emacs configuration, if you don't like it, that's ok because I made it thinking of myself. the code here is tidy so anyone could modify it without great pain.

Installation

Just copy this repository to your emacs configuration path. Nothing else is needed.

Why?

• I can
• I don't like doom emacs
• I don't like spacemacs
• I don't want to learn doom emacs
• I don't want to learn spacemacs
• I don't like Vim

gc

  ;; Minimize garbage collection during startup
  (setq gc-cons-threshold most-positive-fixnum)

  ;; Lower threshold back to 8 MiB (default is 800kB)
  (add-hook 'emacs-startup-hook
       (lambda ()
            (setq gc-cons-threshold (expt 2 23))))

melpa crap, and basic packages installation

melpa, where you get the packages. This also installs use-package, and other packages I use.

  (require 'package)
  (let* ((no-ssl (and (memq system-type '(windows-nt ms-dos))
                      (not (gnutls-available-p))))
             (proto (if no-ssl "http" "https")))
       ;; Comment/uncomment these two lines to enable/disable MELPA and MELPA Stable as desired
       (add-to-list 'package-archives (cons "melpa" (concat proto "://melpa.org/packages/")) t)
       ;;(add-to-list 'package-archives (cons "melpa-stable" (concat proto "://stable.melpa.org/packages/")) t)
       (when (< emacs-major-version 24)
            ;; For important compatibility libraries like cl-lib
            (add-to-list 'package-archives '("gnu" . (concat proto "://elpa.gnu.org/packages/")))))

  (if (< emacs-major-version 27)
       (package-initialize))
  (unless (package-installed-p 'use-package)
       (package-refresh-contents)
       (package-install 'use-package))

Generic packages

Here I install some packages that don't need configuration. Remember to run M-x all-the-icons-install-fonts after the first init to install the fonts.

  (use-package markdown-mode
       :defer 1
       :ensure t
       :init(add-hook 'markdown-mode-hook 'auto-fill-mode))
  (use-package all-the-icons
       :defer 1
       :ensure t)
  (use-package which-key
       :ensure t
       :init (which-key-mode))

Autoindentation

C-c n for indent-buffer. I don't use the rest.

  (setq-default tab-width 5)
  (defvaralias 'sgml-basic-offset 'tab-width)
  (add-hook 'html-mode-hook
       (lambda ()
            (set-fill-column 100)))
  (add-hook 'markdown-mode-hook
       (lambda ()
            (set-fill-column 75)))


  (defun indent-buffer ()
       (interactive)
       (save-excursion
            (indent-region (point-min) (point-max) nil)))
  (global-set-key (kbd "C-c n") 'indent-buffer)
  ;; C bullshit
  (c-set-offset 'arglist-cont-nonempty '+)

Shorcuts

Probably this overwrites another keybinding. But since I overwrited it. I don't think i'd ever use the overwritten.

  (global-set-key (kbd "M-m") 'mark-whole-buffer)
  (global-set-key (kbd "C-c m") 'man)
  (define-key org-mode-map (kbd "C-c p") 'org-publish-current-file)
  (set-frame-font "xos4 Terminus 12")

No idea

  (setq package-enable-at-startup nil) (package-initialize)
  (setq make-backup-files nil) ; stop creating backup~ files
  (setq auto-save-default nil) ; stop creating #autosave# files
  (put 'upcase-region 'disabled nil)
  (defun contextual-menubar (&optional frame)
       "Display the menubar in FRAME (default: selected frame) if on a
  graphical display, but hide it if in terminal."
       (interactive)
       (set-frame-parameter frame 'menu-bar-lines
            (if (display-graphic-p frame)
                 1 0)))
  (add-hook 'after-make-frame-functions 'contextual-menubar)
  (use-package zencoding-mode
       :ensure t
       :defer 1)

My functions

Functions I wrote because emacs lisp is cool and useful.

  (defun sosa/goto-previous-buffer ()
       "Switch to the previous buffer."
       (interactive)
       (switch-to-buffer (other-buffer)))

       (interactive)
       (let (ext-map file-name file-ext prog-name cmd-str)
                                          ; get the file name

            (setq prog-name (cdr (assoc file-ext ext-map)))
            (setq cmd-str (concat prog-name " " file-name))
            (shell-command cmd-str)))

  (defun sosa/repos ()
       (interactive)
       (dired "/home/diego/Escritorio/zpool/repos/"))
  (global-set-key (kbd "C-c r") 'sosa/repos)

Programs

Emacs customization, Here is where most of the configuration is.

Pseudopersonalization

Sane defaults!!!

  (tool-bar-mode -1)
  (menu-bar-mode -1)
  (scroll-bar-mode -1)
  (global-hl-line-mode)
  (set-face-background hl-line-face "#434343")
  (setq-default cursor-type 'box)
  (blink-cursor-mode 1)
  (setq-default major-mode 'text-mode)
  (defalias 'yes-or-no-p 'y-or-n-p)
  ;; Are you experienced?

  (set-face-background 'line-number nil)
  (set-face-background 'line-number-current-line nil)
  (setq-default Man-notify-method 'pushy)

Highlight matching parentheses

Useful for programming in lisp. I don't program in Lisp, but well.

  (show-paren-mode 1)
  (setq show-paren-style 'mixed)

  (setq startup/gc-cons-threshold gc-cons-threshold)
  (setq gc-cons-threshold most-positive-fixnum)
  (defun startup/reset-gc () (setq gc-cons-threshold startup/gc-cons-threshold))
  (add-hook 'emacs-startup-hook 'startup/reset-gc)

Tramp mode shit

(basically) no limit for remote files.

  (set-variable 'tramp-copy-size-limit 122222222222)
  (set-variable 'tramp-inline-compress-start-size 12222222222222)

Lines and columns

Show relative lines in each file. Also display the column in the minibuffer.

  (global-display-line-numbers-mode 1)
  (setq display-line-numbers-type 'relative)
  (column-number-mode 1)

Flycheck

Flycheck is a syntax validator and lintern for programming.

  (use-package flycheck
       :ensure t)

And for raku

  (use-package flycheck-raku
       :ensure t
       :init
       (add-hook 'raku-mode 'flycheck-raku-mode))

Terminal

vterm is better than ansi-term and shit, despite it's kinda slow, it's a price i'm willing to pay. Remember that to compile VTerm you need cmake installed. See the error buffer that is created everytime you try to copmile vterm for further information.

It should use your default shell by default.

  (use-package vterm
       :ensure t)

And to have multiple buffers

  (use-package multi-vterm
       :ensure t
       :bind("C-x C-t" . multi-vterm))

Theme

  (use-package plan9-theme
       :ensure t
       :init(load-theme 'plan9 t))
  (set-cursor-color "purple")
** ctrlf
So, you know, C-s in emacs sucks, so this is a repleacement for that.
#+BEGIN_SRC emacs-lisp
  (use-package ctrlf
       :ensure t
       :defer 1
       :init
       (ctrlf-mode +1))

Programming language things

LSP

Le language server

  (use-package lsp-mode
       :ensure t)

Lisp

Parentheses highlight in lisp modes. So you can easily identify them.

  (use-package rainbow-delimiters
       :ensure t
       :init
       (add-hook 'emacs-lisp-mode-hook 'rainbow-delimiters-mode)
       (add-hook 'lisp-mode-hook 'rainbow-delimiters-mode)
       (add-hook 'scheme-mode-hook 'rainbow-delimiters-mode))

  (setq lisp-indent-offset 5)

Perl

I use LSP for perl.

  (setq perl-indent-level 5)
  (defalias 'perl-mode 'cperl-mode)
  (add-hook 'perl-mode-hook (lambda ()
                                 (lsp)
                                 (irony-mode -1)))
  (load-file "~/.config/emacs/perltidy.el")

C*

This use c-eldoc mode so it prints the function's prototype in the minibuffer. Which is very useful since Irony works when it wants to. LSP is also used for further Programming.

  (use-package c-eldoc
       :ensure t
       :init
       (add-hook 'c-mode-hook 'c-turn-on-eldoc-mode))
  (setq c-default-style "k&r")
  (add-hook 'c-mode-hook (lambda ()
                              (lsp)))

Raku

Raku, the cornerstone of any well designed programming language.

  (setq raku-indent-offset 5)
  (setq raku-exec-path "/home/diego/.local/bin/raku")

HTML & CSS offset

  (setq css-indent-offset 5)
  (setq sgml-basic-offset 5)

org

  (setq org-ellipsis " ")
  (setq org-src-fontify-natively t)
  (setq org-src-tab-acts-natively t)
  (setq org-confirm-babel-evaluate nil)
  (setq org-export-with-smart-quotes t)
  (setq org-src-window-setup 'current-window)
  (add-hook 'org-mode-hook 'org-indent-mode)
  (add-hook 'org-mode-hook 'sosa/no-lines) 
  ;; Syntax highlighting in exports
  (use-package htmlize
       :ensure t)
  (setq org-html-head ""
       org-html-head-extra ""
       org-html-head-include-default-style nil
       org-html-head-include-scripts nil
       org-html-preamble nil
       org-html-postamble nil
       org-html-use-infojs nil)

Keybindings

Here I put functions I won't bother to document because they're so simple.

  (global-set-key (kbd "M-d") 'sosa/kill-inner-word)
  (global-set-key (kbd "M-.") 'repeat)
  (global-set-key (kbd "C-x k") 'kill-buffer)
  (global-set-key (kbd "C-x C-k") 'kill-current-buffer)
  (global-unset-key (kbd "C-x C-b"))
  (global-set-key (kbd "C-x C-b") 'sosa/goto-previous-buffer)

Hunspell

For some reason, there is no ispell spanish in void linux. so i had to fallback to hunspell. which does the same.

  (defvar ispell-program-name "hunspell") ;; Or whatever you use
  ;; (ispell, aspell...)

Dired

Ahhh, the emacs file browser, better than ranger and others… Hide dotfiles:

  (use-package dired-hide-dotfiles
       :ensure t
       :init
       (defun my-dired-mode-hook ()
            "My `dired' mode hook."
            ;; To hide dot-files by default
            (dired-hide-dotfiles-mode)

            ;; To toggle hiding
            (define-key dired-mode-map "." #'dired-hide-dotfiles-mode))

       (add-hook 'dired-mode-hook #'my-dired-mode-hook))
  (use-package async
       :ensure t
       :init (dired-async-mode 1))
  (add-hook 'dired-mode-hook
       (lambda ()
            (dired-hide-details-mode)))

Now let's make the thing lysergic

  (set-face-foreground dired-directory-face "orange")
  (set-face-foreground dired-symlink-face "cyan")
  (set-face-foreground dired-mark-face "green")

  (add-hook 'shell-mode-hook 'flycheck-mode)
  (add-hook 'shell-mode-hook 'company-mode)

  (defun shell-mode-company-init ()
       (setq-local company-backends '((company-shell
                                           company-shell-env
                                           company-etags
                                           company-dabbrev-code))))

  (use-package company-shell
       :ensure t

       (require 'company)
       (add-hook 'shell-mode-hook 'shell-mode-company-init))

CRUX

This thing add sane shortcuts for emacs

  (use-package crux

       :bind("C-k" . 'crux-smart-kill-line)
       :bind("C-c o" . 'crux-open-with)

Dashboard

The dashboard is a good index for your things. So it's useful to have it

Here is an useful function I wrote so you can go to the dashboard (Or create it in case you accidentally killed the buffer)

  (global-set-key (kbd "C-c C-d") 'sosa/goto-dashboard)

  (use-package dashboard
       :ensure t
       :init
       (dashboard-setup-startup-hook)
       (setq dashboard-items '(
                                   (recents	. 7)
                                   (bookmarks . 7)
                                   ))
       (setq dashboard-startup-banner 'logo)
       (setq dashboard-banner-logo-title "Welcome to Editor MACroS")
       (setq dashboard-startup-banner "~/.emacs.d/img/banner.png")
       (setq dashboard-set-heading-icons t)
       (setq dashboard-set-file-icons t))

Modeline

  (use-package doom-modeline
       :ensure t
       :init(doom-modeline-mode)
       :config
       (setq doom-modeline-height 25)
       (setq doom-modeline-hud nil)
       (setq doom-modeline-icon t)
       (setq doom-modeline-major-mode-icon nil)
