I've been using emacs for a while now and dicided that it is time to convert my configs to org mode.

This configuration uses the use-package package from John Wiegley, which is a fantastic way to manage package configurations.

Personal Information

(setq user-full-name "b2r1s8"
      user-mail-address "")

Sane defaults

The default emacs config is ugly and not efficient.

Startup Performance

Make startup faster by reducing the frequency of garbage collection and then use a hook to measure Emacs startup time.

;; The default is 800 kilobytes.  Measured in bytes.
(setq gc-cons-threshold (* 50 1000 1000))

;; Profile emacs startup
(add-hook 'emacs-startup-hook
          (lambda ()
            (message "*** Emacs loaded in %s with %d garbage collections."
                     (format "%.2f seconds"
                             (float-time
                              (time-subtract after-init-time before-init-time)))

Company mode

Company Mode provides a nicer in-buffer completion interface than completion-at-point which is more reminiscent of what you would expect from an IDE. We add a simple configuration to make the keybindings a little more useful (TAB now completes the selection and initiates completion at the current location if needed).

We also use company-box to further enhance the look of the completions with icons and better overall presentation.

Ace window

This packages make easy to move around windows.

• x -> delete window
• m -> swap windows
• M -> move window
• c -> copy window
• j -> select buffer
• n -> select the previous window
• u -> select buffer in the other window
• c -> split window fairly, either vertically or horizontally
• v -> split window vertically
• b -> split window horizontally
• o -> maximize current window
• ? -> show these command bindings

(use-package ace-window

  :bind (("C-o" . ace-window)))

IDE Features with lsp-mode

lsp-mode

We use the excellent lsp-mode to enable IDE-like functionality for many different programming languages via "language servers" that speak the Language Server Protocol. Before trying to set up lsp-mode for a particular language, check out the documentation for your language so that you can learn which language servers are available and how to install them.

The lsp-keymap-prefix setting enables you to define a prefix for where lsp-mode's default keybindings will be added. I highly recommend using the prefix to find out what you can do with lsp-mode in a buffer.

The which-key integration adds helpful descriptions of the various keys so you should be able to learn a lot just by pressing C-c l in a lsp-mode buffer and trying different things that you find there.

(defun efs/lsp-mode-setup ()
  (setq lsp-headerline-breadcrumb-segments '(path-up-to-project file symbols))
  (lsp-headerline-breadcrumb-mode))

(use-package lsp-mode
  :commands (lsp lsp-deferred)
  :hook (lsp-mode . efs/lsp-mode-setup)
  :init
  (setq lsp-keymap-prefix "C-c l")  ;; Or 'C-l', 's-l'
  :config
  (lsp-enable-which-key-integration t))

lsp-ui

lsp-ui is a set of UI enhancements built on top of lsp-mode which make Emacs feel even more like an IDE. Check out the screenshots on the lsp-ui homepage (linked at the beginning of this paragraph) to see examples of what it can do.

  (use-package lsp-ui
    :hook (lsp-mode . lsp-ui-mode)
    :custom
    (lsp-ui-doc-position 'bottom)
    (lsp-ui-sideline-show-diagnostics t)
    (lsp-ui-sideline-show-hover t)
    (lsp-ui-sideline-show-code-actions t)
    (lsp-ui-sideline-update-mode t)
    (lsp-ui-doc-enable t)
    (lsp-ui-doc-show-with-cursor t)
    (lsp-ui-doc-show-with-mouse t))

lsp-treemacs

lsp-treemacs provides nice tree views for different aspects of your code like symbols in a file, references of a symbol, or diagnostic messages (errors and warnings) that are found in your code.

Try these commands with M-x:

• lsp-treemacs-symbols - Show a tree view of the symbols in the current file
• lsp-treemacs-references - Show a tree view for the references of the symbol under the cursor
• lsp-treemacs-error-list - Show a tree view for the diagnostic messages in the project

This package is built on the treemacs package which might be of some interest to you if you like to have a file browser at the left side of your screen in your editor.

  (use-package lsp-treemacs
    :after lsp
    :custom
    (lsp-treemacs-sync-mode 1))

lsp-ivy

lsp-ivy integrates Ivy with lsp-mode to make it easy to search for things by name in your code. When you run these commands, a prompt will appear in the minibuffer allowing you to type part of the name of a symbol in your code. Results will be populated in the minibuffer so that you can find what you're looking for and jump to that location in the code upon selecting the result.

Try these commands with M-x:

• lsp-ivy-workspace-symbol - Search for a symbol name in the current project workspace
• lsp-ivy-global-workspace-symbol - Search for a symbol name in all active project workspaces

  (use-package lsp-ivy)

Ivy

I currently use Ivy, Counsel, and Swiper to navigate around files, buffers, and projects super quickly. Here are some workflow notes on how to best use Ivy:

• While in an Ivy minibuffer, you can search within the current results by using S-Space.
• To quickly jump to an item in the minibuffer, use C-' to get Avy line jump keys.
• To see actions for the selected minibuffer item, use M-o and then press the action's key.
• Super useful: Use C-c C-o to open ivy-occur to open the search results in a separate buffer. From there you can click any item to perform the ivy action.

(use-package ivy
  :diminish
  :bind (("C-s" . swiper)
         :map ivy-minibuffer-map
         ("TAB" . ivy-alt-done)
