#+TITLE: Doom-emacs config
#+AUTHOR: Judah Sotomayor
#+STARTUP: overview

This is the ultra-minimal version of my config.
It includes the bare minimum of comfort.
* Task List
** TODO Reorganize into use-cases rather than packages
* Setting Basics
** Packages
#+begin_src emacs-lisp :tangle "packages.el"
;; -*- no-byte-compile: t; -*-
#+end_src

** Set name, org-roam-directory, etc.
Some basic settings for Emacs
#+begin_src emacs-lisp
(setq tab-always-indent t)
(setq org-roam-directory "~/org/")


(setq user-full-name "Judah Sotomayor"
      user-mail-address "")
#+end_src

#+begin_src emacs-lisp :tangle "packages.el"
(package! noCtrlC
  :recipe (:host nil :type git :repo "https://git.freedomland.xyz/judahsotomayor/noctrlc"))
#+end_src


* Theme and Font
Set the theme.
/Use something dark/
+I also prefer relative line numbers because of *evil* mode+
Relative line numbers don't seem to work, because of folding in Org-mode.
#+begin_src emacs-lisp
(setq doom-theme 'doom-oksolar-dark)
(condition-case nil
    (setq doom-font (font-spec :family "Hack Nerd Font Mono" :size 16 :weight 'medium))
  (error (set-face-attribute 'default nil :height 130)))

(setq auto-save-default nil) ;I don't like autosaving. Let me do it myself.
#+end_src

#+RESULTS:

** Doom splash screen
I really don't like the widgets, and I think it takes longer to load so I get rid of them
#+begin_src emacs-lisp
(remove-hook '+doom-dashboard-functions #'doom-dashboard-widget-shortmenu)
(remove-hook '+doom-dashboard-functions #'doom-dashboard-widget-footer)
#+end_src

Set a sweet splash image
#+begin_src emacs-lisp
(setq fancy-splash-image (concat doom-private-dir "emacs.png"))
#+end_src
* Evil configuration
I want a non-ESC way to get back to normal mode:
#+begin_src emacs-lisp
(map! :desc "Switch to normal mode" :i "C-c" #'evil-normal-state)
(after! org-mode (map! :desc "Delete previous character in insert mode" :i "C-h" #'evil-delete-backward-char))
(map! :desc "Increment number below or after cursor" :n "C-a" #'evil-numbers/inc-at-pt)
(map! :desc "Decrement number below or after cursor" :n "C-x" #'evil-numbers/dec-at-pt)
(map! :n "g j" #'evil-next-visual-line)
(map! :n "g k" #'evil-previous-visual-line)
#+end_src

* Terminal setup
I like to just use bash:
#+begin_src emacs-lisp
(defun bash nil
  "Lauch term with /bin/bash"
  (interactive)
  (term "/bin/bash"))

(defun dash nil
  "Lauch term with /bin/dash"
  (interactive)
  (term "/bin/dash"))

(defun zsh nil
  "Lauch term with /bin/zsh"
  (interactive)
  (term "/bin/zsh"))

#+end_src

#+RESULTS:
: zsh

** Shell mappings
#+begin_src emacs-lisp
(map! :leader (:prefix ("k" . "shell")

      :desc "Start a bash shell"
      :n "b" #'bash

      :desc "Start a dash shell"
      :n "d" #'dash

      :desc "Start a zsh shell"
      :n "z" #'zsh

      :desc "Start an elisp repl"
      :n "e" #'+emacs-lisp/open-repl

      :desc "Start a python repl"
      :n "j" #'+python/open-repl))
#+end_src

#+RESULTS:

,#+RESULTS:

I don't like the modeline in the terminal.
,#+begin_src emacs-lisp
(add-hook 'term-mode-hook 'hide-mode-line-mode)
#+end_src
* Useful Functions
** Get the date from the shell
I want to grab the current date and put it in the buffer.
Because I sometimes use Fish or another shell, it's good to make sure bash is running the command using the src_bash{`-c`}  flag.
#+begin_src emacs-lisp
(defun current-date () (interactive)
    (shell-command-to-string "date '+%Y-%m-%d'"))

 (defun insert-current-date () (interactive)
    (insert (string-trim (current-date))))

(map! :leader
      :desc "Insert the current date into the buffer"
      "i d" #'insert-current-date)
#+end_src

#+RESULTS:
** Convert regex strings to rx
#+begin_src elisp :tangle packages.el
(package! xr)
#+end_src

#+begin_src elisp
(use-package! xr)
#+end_src
* Programming Items
** Editorconfig
I need to make sure some different files work with
#+begin_src emacs-lisp
(after! editorconfig-mode
(add-to-list 'editorconfig-mode-alist
             '(cpp-mode . "cpp")))
#+end_src
** LSP
In order for editorconfig to do its thing, indentation by the lsp must be disabled.
#+begin_src emacs-lisp
(setq lsp-enable-indentation nil)
#+end_src emacs-lisp


* Company-mode for great autocompletes
I don't really want company-mode to run on timeouts.
I want VIM-like autocompletion, where =C-x o= and friends gives me my autocompletion.
#+begin_src emacs-lisp
(after! company-mode
  (setq company-idle-delay nil))
(setq company-idle-delay nil)
#+end_src



* Initializing shell environment variables
** Package
#+begin_src emacs-lisp :tangle "packages.el"
(package! exec-path-from-shell)
#+end_src
** Config
We need to bring in the correct SSH agent values, so that Emacs is aware of where it is running.
#+begin_src emacs-lisp
(use-package! exec-path-from-shell)
(after! exec-path-from-shell
  (dolist (var '("SSH_AUTH_SOCK" "SSH_AGENT_PID" "GPG_AGENT_INFO"))
  (add-to-list 'exec-path-from-shell-variables var))
  (exec-path-from-shell-initialize)
  )
#+end_src

* Init.el
I like to have all my config in one place.
#+begin_src emacs-lisp :tangle "init.el"
;;; init.el -*- lexical-binding: t; -*-

;; This file controls what Doom modules are enabled and what order they load
;; in. Remember to run 'doom sync' after modifying it!

;; NOTE Press 'SPC h d h' (or 'C-h d h' for non-vim users) to access Doom's
;;      documentation. There you'll find a link to Doom's Module Index where all
;;      of our modules are listed, including what flags they support.

;; NOTE Move your cursor over a module's name (or its flags) and press 'K' (or
;;      'C-c c k' for non-vim users) to view its documentation. This works on
;;      flags as well (those symbols that start with a plus).
;;
;;      Alternatively, press 'gd' (or 'C-c c d') on a module to browse its
;;      directory (for easy access to its source code).
