Emacs base configuration for some programming languages

Visual demonstration of the Emacs-Clojure configuration

Default packages

Some basic packages for Scheme Lisp Guile using the geiser configuration, and basic file modes for Elixir programming language, Haskell programming language, Golang, Lua, Scala, Rust and OCaml programming language

(require 'package)

Some misc configurations

• backup dir for "~" files
• Display time
• Inhibit startup screen

(setq backup-directory-alist `(("." . "~/.backup")))
(display-time)

;; not help screen
(setq inhibit-startup-screen t)

Goto some line

Show line numbers temporarily, while prompting the line number input

(global-set-key [remap goto-line] 'goto-line-with-feedback)

(defun goto-line-with-feedback ()
  "Show line numbers temporarily, while prompting for the line number input"
  (interactive)
  (if (and (boundp 'linum-mode)
           linum-mode)
      (call-interactively 'goto-line)
    (unwind-protect
        (progn
          (linum-mode 1)
          (call-interactively 'goto-line))
      (linum-mode -1))))

Common lisp configuration (SBCL)

;; sbcl
(load (expand-file-name "~/quicklisp/slime-helper.el"))
(setq inferior-lisp-program "/usr/local/bin/sbcl")

Default base configuration for clojure

• Automatic parenthesis completion with paredit
• Parenthesis rainbow colors with rainbow-delimiters
• Pop-up suggestions for functions with company-mode

;; enable paredit-mode for clojure files and cider
(add-hook 'cider-repl-mode-hook #'paredit-mode) ;;repl
(add-hook 'clojure-mode-hook 'enable-paredit-mode) ;; enable paredit for clojure files

;; enable company-mode for clojure files and cider
(add-hook 'cider-repl-mode-hook #'company-mode)
(add-hook 'clojure-mode-hook #'company-mode)

;; enable rainbow-delimiter-mode for clojure files and cider
(add-hook 'cider-repl-mode-hook #'rainbow-delimiters-mode)
(add-hook 'clojure-mode-hook #'rainbow-delimiters-mode)

;; best custon color configuration for rainbow-delimiter
