Emacs configuration file

Table des matières

This is my emacs configuration file. It is under version control and available, among other configurations, at this repository: https://github.com/seblemaguer/dotfiles

This configuration relies mainly on melpa and repository named "local-melpa". This local-melpa repository is corresponding to the branch "personal" of my fork of melpa (see here: https://github.com/seblemaguer/melpa/tree/personal )

1 Prerequisite

This part focusing on some baseline prerequisites before the main configuration part

1.1 Daemon mode

First start a server as it is going to be the 99% of my use of emacs.

(server-start)

1.2 Packages

This section is configuring the bootstrap packages (enhancing use-package and support quelpa)

1.2.1 Global

This section focuses on the package management configuration.

We want to be able to have 4 things:

  • Adapt the system package manager (for archlinux tool trizen) + enable use-package-ensure-system-package
(use-package system-packages
    :ensure t
    :config
    (setq system-packages-supported-package-managers
          '(
            (trizen .
                    ((default-sudo . nil)
                     (install . "trizen -S")
                     (search . "trizen -Ss")
                     (uninstall . "trizen -Rns")
                     (update . "trizen -Syu")
                     (clean-cache . "trizen -Sc")
                     (log . "cat /var/log/trizen.log")
                     (get-info . "trizen -Qi")
                     (get-info-remote . "trizen -Si")
                     (list-files-provided-by . "trizen -Ql")
                     (verify-all-packages . "trizen -Qkk")
                     (verify-all-dependencies . "trizen -Dk")
                     (remove-orphaned . "trizen -Rns $(trizen -Qtdq)")
                     (list-installed-packages . "trizen -Qe")
                     (list-installed-packages-all . "trizen -Q")
                     (list-dependencies-of . "trizen -Qi")
                     (noconfirm . "--noconfirm")))
            )

          system-packages-use-sudo nil
          system-packages-package-manager 'trizen)
    )


(use-package use-package-ensure-system-package
  :ensure t)
  • Use an enhanced package list visualizer (paradox)
(use-package paradox
  :ensure t
  :defer t
  :config
  (setq paradox-spinner-type 'progress-bar
        paradox-execute-asynchronously t))
  • Dealing with key-chord support
(use-package use-package-chords
  :ensure t
  :config (key-chord-mode 1))
(defun package-upgrade-all ()
  "Upgrade all packages automatically without showing *Packages* buffer."
  (interactive)
  (package-refresh-contents)
  (let (upgrades)
    (cl-flet ((get-version (name where)
                (let ((pkg (cadr (assq name where))))
                  (when pkg
                    (package-desc-version pkg)))))
      (dolist (package (mapcar #'car package-alist))

                                     in-archive))
            (push (cadr (assq package package-archive-contents))
                  upgrades)))))
    (if upgrades
        (when (yes-or-no-p
               (message "Upgrade %d package%s (%s)? "
                        (length upgrades)
                        (if (= (length upgrades) 1) "" "s")
                        (mapconcat #'package-desc-full-name upgrades ", ")))
          (save-window-excursion
            (dolist (package-desc upgrades)
              (let ((old-package (cadr (assq (package-desc-name package-desc)
                                             package-alist))))
                (package-install package-desc)
                (package-delete  old-package)))))
      (message "All packages are up to date"))))

1.2.2 Quelpa

Quelpa is super useful for developer package management. Adding the adaptation for the use-package makes it configuration file proof.

(use-package quelpa-use-package
    :ensure t
    :init
    (setq quelpa-update-melpa-p nil))

2 Global

This section is about configuring global emacs helpers which are not specific to a dedicated language (or filetype) but are useful for any edition use-case in emacs.

2.1 Undo

In order to have a better and more visual control of undoing, I use undo-tree.

(use-package undo-tree
  :ensure quelpa
  :quelpa (undo-tree :fetcher git :url "http://www.dr-qubit.org/git/undo-tree.git")
  :defer t
  :init

  (setq undo-tree-visualizer-timestamps nil
        undo-tree-visualizer-diff t)

  (global-undo-tree-mode))

2.2 Minor-mode activation

I use some minor modes based on some filetypes. This package is an helper which facilitates these activations.

(use-package auto-minor-mode
  :ensure t
  :defer t)

2.3 Helpers

I define here some global helpers used either in the rest of the file, either available to use at runtime

2.3.1 Authentification

Easy use wrapper around auth-* authentification emacs utils

(defun* my:auth-source-get-passwd (&rest spec &allow-other-keys)
  (let ((founds (apply 'auth-source-search spec)))
    (when founds
      (funcall (plist-get (nth 0 founds) :secret)))))

(defun* my:auth-source-get-user (&rest spec &allow-other-keys)
  (let ((founds (apply 'auth-source-search spec)))
    (when founds
      (plist-get (nth 0 founds) :user))))

2.3.2 Editing as root

Defining a simple helper to edit file as root using tramp

(defun edit-current-file-as-root ()
  "Edit the file that is associated with the current buffer as root"
  (interactive)
  (if (buffer-file-name)
      (progn
        (setq file (concat "/sudo:localhost:" (buffer-file-name)))
        (find-file file))
    (message "Current buffer does not have an associated file.")))

2.4 TODO Accent problem

(load-library "iso-transl")

2.5 TODO Message buffer

The main idea here is to add a timestamp to the messages as it helps to understand the sequence of problems. For now the advice is not activated as it causes some problems.

(defvar debug-messages nil)

(defun current-time-microseconds ()
  (let* ((nowtime (current-time))
         (now-ms (nth 2 nowtime)))
    (concat (format-time-string "[%Y-%m-%d %T" nowtime) (format ".%d] " now-ms))))

(defadvice message (before who-said-that activate)
  "Find out who said that thing. and say so."
  (let ((trace nil) (n 1) (frame nil))
    (when debug-messages
        (progn
          (while (setq frame (backtrace-frame n))
            (setq n     (1+ n)
                  trace (cons (cadr frame) trace)) )

          (ad-set-arg 0 (concat (format-time-string "[%Y-%m-%d %T %Z] ") "<<%S>>:\n" (ad-get-arg 0)))
          (ad-set-args 1 (cons trace (ad-get-args 1)))))))

2.6 Encoding

Define the global encoding as utf-8 english US related. Of course, it is possible de locally change this information per buffer.

(setq system-time-locale "en_US.utf8")
(prefer-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)

2.7 Folding

In order to have a unify folding support, I use origami in couple with hydra. The advantage of hydra is to see all the alternatives more easily. Also inspire from https://github.com/Schnouki/dotfiles/blob/master/emacs/init-20-dev.el

(use-package origami
  :ensure quelpa
  :quelpa (origami :repo "seblemaguer/origami.el" :fetcher github)
  :custom
  (origami-show-fold-header t)

  :custom-face
  (origami-fold-replacement-face ((t (:inherit magit-diff-context-highlight))))
  (origami-fold-fringe-face ((t (:inherit magit-diff-context-highlight))))

  :init
  (defhydra origami-hydra (:color blue :hint none)
    "
      _:_: recursively toggle node       _a_: toggle all nodes    _t_: toggle node
      _o_: show only current node        _u_: undo                _r_: redo
      _R_: reset
      "
    (":" origami-recursively-toggle-node)
    ("a" origami-toggle-all-nodes)
    ("t" origami-toggle-node)
    ("o" origami-show-only-node)
    ("u" origami-undo)
    ("r" origami-redo)
    ("R" origami-reset))

  :bind (:map origami-mode-map
              ("C-:" . origami-hydra/body))
  :config
  (face-spec-reset-face 'origami-fold-header-face))

2.8 Edition

This section is dedicated to hacks and helpers to facilitate global edition.

2.8.1 Edit simultanously multiple region

Sometimes it can be useful to edit multiple region at once. To do that, I use iedit.

(use-package iedit
  :ensure t
  :config
  (delete-selection-mode t))

2.8.2 Alignment

I defined this helper to as I like to align equations based on the equal sign.

(defun align-to-equals (begin end)
  "Align region to equal signs"
   (interactive "r")
   (align-regexp begin end "\\(\\s-*\\)=" 1 1 ))

2.9 Recent file

Opening recent files is always an easy and fast shortcut. Some files should be ignored though. That leads to this configuration

(use-package recentf
  :init
  (recentf-mode 1)

  :config

  ;; Increase limit
  (setq recentf-max-menu-items 100)

  ;; Emacs
  (add-to-list 'recentf-exclude (format "%s/.orhc-bibtex-cache" (getenv "HOME")))
  (add-to-list 'recentf-exclude (format "%s/configuration/emacs\\.d/\\(?!\\(main.*\\)\\)" (getenv "HOME")))
  (add-to-list 'recentf-exclude (format "%s/\\.emacs\\.d/.*" (getenv "HOME")))

  ;; Some caches
  (add-to-list 'recentf-exclude (format "%s/\\.ido\\.last" (getenv "HOME")))
  (add-to-list 'recentf-exclude (format "%s/\\.recentf" (getenv "HOME")))


  ;; elfeed
  (add-to-list 'recentf-exclude (format "%s/\\.elfeed/.*" (getenv "HOME")))
  (add-to-list 'recentf-exclude (format "%s/Dropbox/emacs/elfeed/.*" (getenv "HOME")))

  ;; Org-mode organisation
  (add-to-list 'recentf-exclude (format "%s/Dropbox/org/organisation/.*" (getenv "HOME")))

  ;; Org/todo/calendars
  (add-to-list 'recentf-exclude ".*todo.org")
  (add-to-list 'recentf-exclude (format "%s/Calendars/.*" (getenv "HOME")))

  ;; Maildir
  (add-to-list 'recentf-exclude (format "%s/maildir.*" (getenv "HOME"))))

2.10 Backup files

This section is dedicated to deal with backups. The main logic is to exlude some specific files (either because of they are sensitive, either because they are just results of a process). For the other ones, I want to have an easy way to navigate in it.

2.10.1 Global backup configuration

This the global backup configuration. For that I adapted a little bit the wonderful snapshot-timemachine package.

(use-package snapshot-timemachine
  :ensure t
  :init

  ;; Default Backup directory
  (defvar backup-directory "~/.emacs.d/backups/")
  (setq backup-directory-alist `((".*" . ,backup-directory)))

  (when (not (file-exists-p backup-directory))
    (make-directory backup-directory t))

  ;; Auto-save
  (defvar auto-save-directory "~/.emacs.d/auto-save/")
  (setq auto-save-file-name-transforms `((".*" ,auto-save-directory t)))

  (when (not (file-exists-p auto-save-directory))
    (make-directory auto-save-directory t))

  ;; Tramp backup
  (defvar tramp-backup-directory "~/.emacs.d/tramp-backups/")
  (setq tramp-backup-directory-alist `((".*" . ,tramp-backup-directory)))

  (when (not (file-exists-p tramp-backup-directory))
    (make-directory tramp-backup-directory t))

  (setq make-backup-files t               ; backup of a file the first time it is saved.
        backup-by-copying t               ; don't clobber symlinks
        version-control t                 ; version numbers for backup files
        delete-old-versions t             ; delete excess backup files silently
        delete-by-moving-to-trash t
        kept-old-versions 6               ; oldest versions to keep when a new numbered backup is made (default: 2)
        kept-new-versions 9               ; newest versions to keep when a new numbered backup is made (default: 2)
        auto-save-default t               ; auto-save every buffer that visits a file
        auto-save-timeout 20              ; number of seconds idle time before auto-save (default: 30)
        auto-save-interval 200            ; number of keystrokes between auto-saves (default: 300)
        )

  :config

  (defun snapshot-timemachine-backup-finder (file)
    "Find snapshots of FILE in rsnapshot backups."
    (let* ((file (expand-file-name file))
           (file-adapted (replace-regexp-in-string "/" "!" file))
           (backup-files(directory-files backup-directory t (format "%s.*" file-adapted))))
      (seq-map-indexed (lambda (backup-file index)
                         (make-snapshot :id index
                                        :name (format "%d" index)
                                        :file backup-file
                                        :date (nth 5 (file-attributes backup-file))))
                       backup-files)))

  (setq snapshot-timemachine-snapshot-finder #'snapshot-timemachine-backup-finder))

2.10.2 Sensitive mode

There are some files which are not desired to be backed up. This part goal is to setup this "avoiding saving" spécificities.

(define-minor-mode sensitive-mode
  "For sensitive files like password lists.
It disables backup creation and auto saving.

With no argument, this command toggles the mode.
Non-null prefix argument turns on the mode.
Null prefix argument turns off the mode."
  ;; The initial value.
  nil
  ;; The indicator for the mode line.
  " Sensitive"
  ;; The minor mode bindings.
  nil
  (if (symbol-value sensitive-mode)
      (progn
        ;; disable backups
        (set (make-local-variable 'backup-inhibited) t)
        ;; disable auto-save
        (if auto-save-default
            (auto-save-mode -1)))
                                        ;resort to default value of backup-inhibited
    (kill-local-variable 'backup-inhibited)
                                        ;resort to default auto save setting
    (if auto-save-default
        (auto-save-mode 1))))


(add-to-list 'auto-minor-mode-alist '("\\.git/.*\\'" . sensitive-mode))
(add-to-list 'auto-minor-mode-alist '("emacs\\.d/.*\\'" . sensitive-mode))
(add-to-list 'auto-minor-mode-alist '("emacs\\.d/emms/.*\\'" . sensitive-mode))
(add-to-list 'auto-minor-mode-alist '("Calendars/.*.org\\'" . sensitive-mode))
(add-to-list 'auto-minor-mode-alist '("\\.gpg\\'" . sensitive-mode))

2.11 Copy/Pasted

Baseline configuration for copy/pasting

(setq mouse-drag-copy-region nil
      x-select-enable-primary nil
      x-select-enable-clipboard t
      select-active-regions t)

2.12 Spell

Configuration of the (fly) spelling for emacs. For spelling, I am using aspell.

(use-package flyspell
  :ensure t
  :config

  ;; Set programms
  (setq-default ispell-program-name "aspell")
  (setq-default ispell-list-command "--list")

  ;; Refresh flyspell after directory change
  (defun flyspell-buffer-after-pdict-save (&rest _)
    (flyspell-buffer))
  (advice-add 'ispell-pdict-save :after #'flyspell-buffer-after-pdict-save)

  ;; Popup
  (defun flyspell-emacs-popup-textual (event poss word)
    "A textual flyspell popup menu."
    (require 'popup)
    (let* ((corrects (if flyspell-sort-corrections
                         (sort (car (cdr (cdr poss))) 'string<)
                       (car (cdr (cdr poss)))))
           (cor-menu (if (consp corrects)
                         (mapcar (lambda (correct)
                                   (list correct correct))
                                 corrects)
                       '()))
           (affix (car (cdr (cdr (cdr poss)))))
           show-affix-info
           (base-menu  (let ((save (if (and (consp affix) show-affix-info)
                                       (list
                                        (list (concat "Save affix: " (car affix))
                                              'save)
                                        '("Accept (session)" session)
                                        '("Accept (buffer)" buffer))
                                     '(("Save word" save)
                                       ("Accept (session)" session)
                                       ("Accept (buffer)" buffer)))))
                         (if (consp cor-menu)
                             (append cor-menu (cons "" save))
                           save)))
           (menu (mapcar
                  (lambda (arg) (if (consp arg) (car arg) arg))
                  base-menu)))
      (cadr (assoc (popup-menu* menu :scroll-bar t) base-menu))))


  (defun flyspell-emacs-popup-choose (org-fun event poss word)
    (if (window-system)
        (funcall org-fun event poss word)
      (flyspell-emacs-popup-textual event poss word)))

  (eval-after-load "flyspell"
    '(progn
       (advice-add 'flyspell-emacs-popup :around #'flyspell-emacs-popup-choose)))
  )

2.13 Fixme

To deal with the fixme, I relie on two part: fic-mode for the highlighting and occur for the listing.

(use-package fic-mode
  :commands fic-mode
  :ensure t
  :init (add-hook 'prog-mode-hook 'fic-mode)
  :config

  (defun fic-view-listing ()
    "Use occur to list related FIXME keywords"
    (interactive)
    (occur "\\<\\(FIXME\\|WRITEME\\|WRITEME!\\|TODO\\|BUG\\):?"))
  )

2.14 Minibuffer

Minibuffer configuration part. Nothing really outstanding, just the classical stuff.

(use-package minibuffer
  :config
  (setq read-file-name-completion-ignore-case t
        completion-ignore-case t
        resize-mini-windows t)
  (file-name-shadow-mode 1)

  (add-hook 'eval-expression-minibuffer-setup-hook #'eldoc-mode))

2.15 Buffers

Some buffer specificities configuration like how to deal with trailing whitespaces or the fill-column for example.

;; Open Large file
(use-package vlf
  :ensure t
  :config
  (require 'vlf-setup))

;; Delete trailing-whitespace
(add-hook 'before-save-hook 'delete-trailing-whitespace)

;; Unify the buffer name style
(eval-after-load "uniquify"
  '(progn
     (setq uniquify-buffer-name-style 'forward)))

;; Redefine fill-column as my screen is not 80 chars :D
(setq-default fill-column 100)

2.16 Productivity behavior

This part is dedicated to ensure productivity configuration. This involves mainly isolating, capturing and bibliography.

2.16.1 Dark room

Sometimes I just want to ignore everything except the current document. Darkroom is exactly designed for that

(use-package darkroom :ensure t)

2.16.2 ORG/Web tools

Org-web-tools is a nice package which allows to sniff a webpage and convert it into org-mode format. This is really useful to homogeneise documentation.

(use-package org-web-tools :ensure t)

2.16.3 Biblio

This part focus on bibliography/library configuration. The goal is to have a global configuration to organize read papers or "to read" papers. This is mainly based on https://codearsonist.com/reading-for-programmers

(use-package ivy-bibtex
  :ensure t
  :config
  (setq ivy-bibtex-bibliography "~/Dropbox/org/work/biblio/index.bib" ;; where your references are stored
        ivy-bibtex-library-path "~/Dropbox/org/work/biblio/lib/" ;; where your pdfs etc are stored
        ivy-bibtex-notes-path "~/Dropbox/org/work/biblio/index.org" ;; where your notes are stored
        bibtex-completion-bibliography "~/Dropbox/org/work/biblio/index.bib" ;; writing completion
        bibtex-completion-notes-path "~/Dropbox/org/work/biblio/index.org"))

(use-package org-ref
  :after org
  :ensure t
  :chords
  (("uu"  . org-ref-cite-hydra/body))
  :init
  (setq org-ref-completion-library 'org-ref-ivy-cite
        org-ref-notes-directory "~/Dropbox/org/work/biblio"
        org-ref-bibliography-notes "~/Dropbox/org/work/biblio/index.org"
        org-ref-default-bibliography '("~/Dropbox/org/work/biblio/index.bib")

2.16.4 Paper

As I write papers, it is useful to have some helper to start to have the inspiration.

2.17 Process management

I want to have some services and processes managed directly in emacs. This services/processes are closely related to my emacs use and there have to be shutdown when emacs is stopping.

2.17.1 Services

The main use case (actually the only for now) is the imap notification system. To do so I use the couple prodigy (to start the process in emacs) and imapnotify to actually activate the push service. Internally, imapnotify is going to call emacsclient to notify the user about a new mail.

(use-package prodigy
  :ensure quelpa
  :quelpa (prodigy :fetcher github :repo "seblemaguer/prodigy.el" :branch "auto-start")
  :config

  (prodigy-define-service
    :name "Saarland imap notify"
    :command "imapnotify"
    :args '("-c" "~/configuration/imapnotify/saarland.js")
    :tags '(work mail)
    :stop-signal 'sigterm
    :auto-start t
    :kill-process-buffer-on-stop t)

  (prodigy-define-service
    :name "hikoseb imap notify"
    :command "imapnotify"
    :args '("-c" "~/configuration/imapnotify/hikoseb.js")
    :tags '(perso mail)
    :stop-signal 'sigterm
    :auto-start t
    :kill-process-buffer-on-stop t)

  (prodigy-define-service
    :name "sebgmail imap notify"
    :command "imapnotify"
    :args '("-c" "~/configuration/imapnotify/sebgmail.js")
    :tags '(perso mail)
    :stop-signal 'sigterm
    :auto-start t
    :kill-process-buffer-on-stop t)

  (prodigy-define-service
    :name "DFKI imap notify"
    :command "imapnotify"
    :args '("-c" "~/configuration/imapnotify/dfki.js")
    :tags '(work mail)
    :stop-signal 'sigterm
    :auto-start t
    :kill-process-buffer-on-stop t)

  (prodigy-define-service
    :name "MMCI imap notify"
    :command "imapnotify"
    :args '("-c" "~/configuration/imapnotify/mmci.js")
    :tags '(work mail)
    :stop-signal 'sigterm
    :auto-start t
    :kill-process-buffer-on-stop t)

    (prodigy-auto-start)
  )

2.17.2 System daemons

With this package I can also manage my system services (tested on archlinux).

(use-package daemons :ensure t)

2.17.3 Background process configuration

Starting process in background is really nice to avoid being spammed. So let's make it available

(defun my-bpr-on-start (process)
  "Routine to allow colors in commint buffer"
  (set-process-filter process 'comint-output-filter))

(use-package bpr
  :ensure t
  :after projectile
  :config
  (setq bpr-colorize-output t
        bpr-close-after-success t
        bpr-use-projectile t
        bpr-process-mode #'comint-mode
        bpr-window-creator #'split-window-vertically
        bpr-on-start 'my-bpr-on-start))

2.18 Environment control helpers

I prefer to control some hardware using emacs directly. For now the keyboard, the screen and the sound.

2.18.1 desktop environment

Thanks to desktop environement, I can control the keyboard and the screen brightness.

(use-package desktop-environment
  :ensure t
  :config
  (setq desktop-environment-brightness-normal-increment "-inc 10"
        desktop-environment-brightness-normal-decrement "-dec 10"
        desktop-environment-brightness-small-increment "-inc 5"
        desktop-environment-brightness-small-decrement "-dec 5"
        desktop-environment-brightness-get-command "xbacklight -get"
        desktop-environment-brightness-set-command "xbacklight"
        )
  (desktop-environment-mode))

2.18.2 pulseaudio

Thanks to pulseaudio-control, I can control my soundcard.

(use-package pulseaudio-control
  :ensure t
  :config
  (setq pulseaudio-control--current-sink "@DEFAULT_SINK@"))

2.19 Language interaction (LSP)

LSP is a set of helper to interact with external "ide" tools and provide their functionalities into emacs. This has been proven useful, especially for java editing.

(use-package lsp-mode
  :ensure t
  :init (setq lsp-inhibit-message t
              lsp-eldoc-render-all nil
              lsp-highlight-symbol-at-point nil))

(use-package company-lsp
  :after  company
  :ensure t
  :config
  (setq company-lsp-enable-snippet t
        company-lsp-cache-candidates t))

(use-package lsp-ui
  :ensure t
  :config
  (setq lsp-ui-sideline-enable t
        lsp-ui-sideline-show-symbol t
        lsp-ui-sideline-show-hover t
        lsp-ui-sideline-show-code-actions t
        lsp-ui-sideline-update-mode 'point))

3 Completion

This part focuses on completion configuration. Language specific configurations are not done here but in the dedicate language configuration part. This section is just for global configuration.

3.1 Ivy/swipper/counsel

I do prefer vertical completion, which is why I use extensively Ivy and extensions.

(use-package ivy
  :ensure t
  :config
  (ivy-mode)
  (setq ivy-display-style 'fancy
        ivy-use-virtual-buffers t
        enable-recursive-minibuffers t
        ivy-use-selectable-prompt t))


(use-package counsel
  :ensure t
  :config
  (global-set-key (kbd "M-x") 'counsel-M-x)
  (global-set-key (kbd "C-x C-f") 'counsel-find-file))

3.2 Company

In order to have inline completion, really important for coding, I use company. However I adapted some facing attributes. Each language is also adding its backend when needed. Therefore, only global configuration here.

(use-package company
  :ensure t
  :config
  ;; Global
  (setq company-idle-delay 1
        company-minimum-prefix-length 1
        company-show-numbers t
        company-tooltip-limit 20)


  ;; Facing
  (unless (face-attribute 'company-tooltip :background)
    (set-face-attribute 'company-tooltip nil :background "black" :foreground "gray40")
    (set-face-attribute 'company-tooltip-selection nil :inherit 'company-tooltip :background "gray15")
    (set-face-attribute 'company-preview nil :background "black")
    (set-face-attribute 'company-preview-common nil :inherit 'company-preview :foreground "gray40")
    (set-face-attribute 'company-scrollbar-bg nil :inherit 'company-tooltip :background "gray20")
    (set-face-attribute 'company-scrollbar-fg nil :background "gray40"))

  ;; Default backends
  (setq company-backends '((company-files)))

  ;; Activating globally
  (global-company-mode t))


(use-package company-quickhelp
  :ensure t
  :after company
  :config
  (company-quickhelp-mode 1))

3.3 Helm

(use-package helm
  :ensure t
  :config
  (setq helm-scroll-amount 4 ; scroll 4 lines other window using M-<next>/M-<prior>
        helm-quick-update t ; do not display invisible candidates
        helm-idle-delay 0.01 ; be idle for this many seconds, before updating in delayed sources.
        helm-input-idle-delay 0.01 ; be idle for this many seconds, before updating candidate buffer
        helm-show-completion-display-function #'helm-show-completion-default-display-function
        helm-split-window-default-side 'below ;; open helm buffer in another window
        helm-split-window-inside-p t ;; open helm buffer inside current window, not occupy whole other window
        helm-candidate-number-limit 200 ; limit the number of displayed canidates
        helm-move-to-line-cycle-in-source nil ; move to end or beginning of source when reaching top or bottom of source.
        )
  )

3.4 Templating

I use templates for 2 use cases: the buffer edition and the file specific templates. Both are relying on yasnippet.

3.4.1 Edition templates

The default configuration of yasnippet consists of activating it and plugging it with company. Ivy-yasnippet is used for snippet discovery.

(use-package yasnippet
  :ensure t
  :config

  ;; Adding yasnippet support to company
  (add-to-list 'company-backends '(company-yasnippet))

  ;; Activate global
  (yas-global-mode))

(use-package yasnippet-snippets
  :ensure t
  )

(use-package ivy-yasnippet
  :ensure t)

3.4.2 Filetype templates

This part is using yatemplate (an over-layer of yasnippet) coupled with auto-insert to have a set of file type dedicated templates. The templates are available in third_parties/templates directory.

(use-package yatemplate
  :ensure t
  :after yasnippet
  :config

  ;; Define template directory
  (setq yatemplate-dir (concat config-basedir "/third_parties/templates"))

  ;; Coupling with auto-insert
  (setq auto-insert-alist nil)
  (yatemplate-fill-alist)
  ;; (add-hook 'find-file-hook 'auto-insert)
  )

4 Filetype

Now that we have achieved the global configuration, I am going to focus on the language specific configuration.

4.1 C/C++

C and C++ configuration is mainly relying on irony. Some minor adaptations, like the compilation part, are also integrated.

4.1.1 Irony main configuration

We just load irony add support for c derivative mode.

(use-package irony
  :ensure t
  :defer t
  :hook ((c-mode . irony-mode)
         (objc-mode . irony-mode)
         (c++-mode .irony-mode)))

4.1.2 Checking/documentation

(use-package flycheck-irony
  :ensure t
  :after (flycheck irony)
  :defer t)

(use-package irony-eldoc
  :ensure t
  :after (irony)
  :defer t)

4.1.3 Completion

For the completion, I am relying on company and irony. The configuration consists of add irony into company backend.

(use-package company-irony
  :ensure t
  :hook (irony-mode . (lambda () (add-to-list (make-local-variable 'company-backends) '(company-irony)))))

(use-package company-irony-c-headers
  :ensure t
  :hook (irony-mode . (lambda () (add-to-list (make-local-variable 'company-backends) '(company-irony-c-headers)))))

4.1.4 Adapt compilation

Sometimes, I don't want to have a makefile or any complicated project compilation. So I just use gcc/g++. Therefore, here, either there is a makefile and use it, either there is none and I use gcc/++ directly.

(add-hook 'c-mode-hook
          (lambda ()
            (unless (or (file-exists-p "Makefile") (boundp 'buffer-file-name))
              (set (make-local-variable 'compile-command)
                   (let ((file (file-name-nondirectory buffer-file-name)))
                     (concat "gcc -g -Wall -Wextra -o " (file-name-sans-extension file) " " file))))))


(add-hook 'c++-mode-hook
          (lambda ()
            (unless (file-exists-p "Makefile")
              (set (make-local-variable 'compile-command)
                   (let ((file (file-name-nondirectory buffer-file-name)))
                     (concat "g++ -g -Wall -Wextra -o " (file-name-sans-extension file) " " file))))))

4.1.5 C++ specificities

For C++, I use a dedicated font lock.

(use-package modern-cpp-font-lock :ensure t)

4.2 Configuration and log files

This part is dedicated to unix and more general configuration files as well as logs.

4.2.1 Default unix configuration

Config-general-mode is applied for all unix configuration files.

(use-package config-general-mode
  :ensure t
  :mode ("\\.conf$" "\\.*rc$"))

4.2.2 Authinfo

I developed a dedicated mode for syntax highlighting authinfo files. For now, it is not stable enough to be on melpa so I use quelpa.

(use-package authinfo-mode
  :ensure quelpa
  :quelpa (authinfo-mode :repo "seblemaguer/authinfo-mode" :fetcher github)
  :mode ("\\.authinfo\\(?:\\.gpg\\)\\'" . authinfo-mode))

4.2.3 Apache

(use-package apache-mode
  :ensure t
  :mode ("\\.htaccess\\'" "httpd\\.conf\\'" "srm\\.conf\\'"
         "access\\.conf\\'" "sites-\\(available\\|enabled\\)/"))

4.2.4 SSH configuration

(use-package ssh-config-mode
  :ensure t
  :mode ("/\\.ssh/config\\'" "/system/ssh\\'" "/sshd?_config\\'" "/known_hosts\\'" "/authorized_keys2?\\'")
  :hook (ssh-config-mode . turn-on-font-lock)

  :config
  (autoload 'ssh-config-mode "ssh-config-mode" t))

4.2.5 Logview

(use-package logview
  :ensure t
  :mode ("syslog\\(?:\\.[0-9]+\\)" "\\.log\\(?:\\.[0-9]+\\)?\\'"))

  :ensure t
  :mode (".yaml$"))

  :defer t
  :mode ("\\.scss\\'")
  :config
  (autoload 'scss-mode "scss-mode")
  (setq scss-compile-at-save 'nil))

(use-package csv-mode
  :ensure t
  :defer t
  :config

  ;; Define separators
  (setq csv-separators '("," ";" ":" " ")))


  ;; Subpackages

  :ensure t
  :init
  (defvar default-tab-width nil)

  :mode ("\\.dot\\'"))

4.7 Java based

(use-package lsp-java
  :ensure t
  :requires (lsp-ui-flycheck lsp-ui-sideline)
  :hook
  (java-mode . (lambda () (add-to-list (make-local-variable 'company-backends) 'company-lsp)))
  (java-mode . lsp-java-enable)
  (java-mode . flycheck-mode)
  (java-mode . (lambda () (lsp-ui-flycheck-enable t)))
  (java-mode . lsp-ui-sideline-mode)
  :config
  (setq lsp-java-save-action-organize-imports nil))

4.7.2 Snippets
