First start

When pulling the repository the first time, an initial init.el needs to be setup. After start it will replace itself with the configuration from init.org

This function updates init.el whenever changes in init.org are made. The update will be active after saving.

  the code blocks are tangled, and the tangled file is compiled."

Projectile

Manage projects and jump quickly between its files

  (use-package projectile
    :ensure t
    :defer t
    :bind
    (("C-c p p" . projectile-switch-project)
     ("C-c p c" . projectile-command-map)
     ("C-c p s s" . projectile-ag))
    :init
    (setq-default projectile-cache-file (concat MY--PATH_USER_LOCAL ".projectile-cache")
                  projectile-known-projects-file (concat MY--PATH_USER_LOCAL ".projectile-bookmarks"))
    :config
    (projectile-mode t)
    (setq-default projectile-completion-system 'ivy
                  projectile-enable-caching t
                  projectile-mode-line '(:eval (projectile-project-name))))

smartparens

(use-package smartparens
  :ensure t
  :diminish smartparens-mode
  :config
  (setq sp-show-pair-from-inside nil)
  (require 'smartparens-config))

lisp

  (add-hook 'emacs-lisp-mode-hook 'company/elisp-mode-hook)

web

apt install npm sudo npm install -g vscode-html-languageserver-bin evtl alternativ typescript-language-server?

  (use-package web-mode
    :ensure t
    :defer t
    :mode
    ("\\.phtml\\'"
     "\\.tpl\\.php\\'"
     "\\.djhtml\\'"
     "\\.[t]?html?\\'")
    :config
    (setq web-mode-enable-auto-closing t
          web-mode-enable-auto-pairing t)
    (add-hook 'web-mode-hook 'smartparens-mode))

Python

Systemseitig muss python-language-server installiert sein: pip3 install 'python-language-server[all]'

für andere language servers https://github.com/emacs-lsp/lsp-mode#install-language-server

(if (string-equal system-type "gnu/linux")
   (defun my/postactivatehook ()
     (setq lsp-python-ms-extra-paths pyvenv-virtual-env))
 
 (use-package pyvenv
   :ensure t
   :config
   (setenv "WORKON_HOME" (expand-file-name "~/Archiv/Programmierprojekte/Python/virtualenv/"))
   (add-hook 'pyvenv-post-activate-hooks 'my/postactivatehook))

 (use-package virtualenvwrapper
   :ensure t
   :hook (venv-postmkvirtualenv . (lambda() (shell-command "pip3 install importmagic epc")))
   :config
   (setq venv-location (expand-file-name "~/Archiv/Programmierprojekte/Python/virtualenv/")))

 (use-package lsp-python-ms
   :ensure t
   :after lsp-mode python))
  ; :custom (lsp-python-executable-cmd "python3"))

beancount

Installation

sudo su
cd /opt
python3 -m venv beancount
source ./beancount/bin/activate
pip3 install wheel
pip3 install beancount
sleep 100
echo "shell running!"
deactivate

  (if (string-equal system-type "gnu/linux")
      (use-package beancount
        :load-path "user-global/elisp"
;        :ensure t
        :defer t
        :mode
        ("\\.beancount$" . beancount-mode)
        :init
        (add-hook 'beancount-mode-hook 'company/beancount-mode-hook)
  ;    (add-hook 'beancount-mode-hook (pyvenv-activate "/opt/beancount"))
    ;  (setenv "PATH"
    ;          (concat "/opt/beancount/bin:"
    ;                  (getenv "PATH")))
        :config
        (setq beancount-filename-main "/home/marc/Archiv/Finanzen/Transaktionen/transactions.beancount")))

To support org-babel, check if it can find the symlink to ob-beancount.el

  orgpath=`find /home/marc/.emacs.d/elpa/ -type d -name "org-plus*" -print`
  beansym="$orgpath/ob-beancount.el
  bean="/home/marc/Archiv/Programmierprojekte/Lisp/beancount-mode/ob-beancount.el"

  if [ -h "$beansym" ]
  then
    echo "$beansym found"
  elif [ -e "$bean" ]
  then
    echo "creating symlink"
    ln -s "$bean" "$beansym"
  else
    echo "$bean not found, symlink creation aborted"
  fi

Fava is strongly recommended.

cd /opt
python3 -m venv fava
source ./fava/bin/activate
pip3 install wheel
pip3 install fava
deactivate

Start fava with fava my_file.beancount

It is accessable on this URL: Fava Beancount-mode can start fava and open the URL right away.
