* Setup home folder structure

  This section sets up my preferred set of initial folders inside my home directory.

  #+NAME: Setup home folder strucuture
  #+BEGIN_SRC shell
  cd ~/
  mkdir Documents
  mkdir Downloads
  #+END_SRC


* Update and install packages

  To get started we ensure the package manager is up to date.

  #+NAME: Update system packages
  #+BEGIN_SRC shell
  sudo apt-get update && sudo apt-get upgrade
  #+END_SRC

  #+RESULTS: Update system packages


  Next we install a series of standard packages that form part of our workflow or
  are dependencies for other tools in our environment.

  #+NAME: Install standard packages 
  #+BEGIN_SRC shell
  sudo apt-get install -y git curl wget locales xclip tmux net-tools less
  \ software-properties-common htop wget apt-transport-https ca-certificates mutt
  #+END_SRC


  We use [[https://pandoc.org/][pandoc]] for documentation export from spacemacs.

  #+NAME: Install pandoc
  #+BEGIN_SRC shell
  curl -L -O https://github.com/jgm/pandoc/releases/download/2.7.3/pandoc-2.7.3-1-amd64.deb  
  sudo dpkg -i /tmp/pandoc-2.7.3-1-amd64.deb
  #+END_SRC


  For additional package management we use node. The code below installs node ~12~.

  #+NAME: Install node
  #+BEGIN_SRC shell 
  sudo curl  -sL https://deb.nodesource.com/setup_12.x | sudo bash -
  sudo apt-get install -y nodejs
  #+END_SRC

  
  For managing secrets we use [[https://bitwarden.com/][bitwarden]] which provides a great [[https://github.com/bitwarden/cli][cli utility]].

  #+NAME: Install bitwarden and login
  #+BEGIN_SRC shell
  export account=[BITWARDEN_ACCOUNT]
  sudo npm install -g @bitwarden/cli 
  bw login $account
  #+END_SRC


  For working with google cloud platform we use the [[https://cloud.google.com/sdk/][GCP SDK]], which provides our cli tools.

  #+NAME: Install google cloud sdk
  #+BEGIN_SRC shell
  # Add the Cloud SDK distribution URI as a package source: 
  echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] https://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
  
  # Import the Google Cloud public key: 
  curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key --keyring /usr/share/keyrings/cloud.google.gpg add -

  # Update and install the Cloud SDK: 
  sudo apt-get update && sudo apt-get install google-cloud-sdk
  #+END_SRC


  For cloud infrastructure deployments we use [[https://www.terraform.io/][terraforms]].

  #+NAME: Install hashicorp terraforms
  #+BEGIN_SRC shell
  # Download the binary
  wget 'https://releases.hashicorp.com/terraform/0.12.9/terraform_0.12.9_linux_amd64.zip'

  # Unzip it
  unzip *.zip

  # Move the binary to path
  sudo mv terraform /usr/bin/

  # Clean up
  rm *amd64.zip 
  #+END_SRC

  #+RESULTS:
  | Archive:   | terraform_0.12.9_linux_amd64.zip |
  | inflating: | terraform                        |


  For ad-hoc system administration we use ansible

  #+NAME: Install ansible
  #+BEGIN_SRC shell
  sudo yum install -y ansible
  #+END_SRC


* Install spacemacs

  A key component in our environment is spacemacs. The section below will setup
  version ~27.0.50~ of emacs and then spacemacs on top.

  #+NAME: Clone the emacs repository
  #+BEGIN_SRC tmate
  git clone -b stable  --depth=1 https://github.com/ii/emacs
  #+END_SRC

  #+NAME: Install dependencies
  #+BEGIN_SRC tmate
  sudo apt-get install autoconf make gcc texinfo libgtk-3-dev libxpm-dev libjpeg-dev libgif-dev libtiff5-dev libgnutls28-dev libncurses5-dev 
  #+END_SRC

  #+NAME: Compile and install emacs
  #+BEGIN_SRC tmate
  cd /emacs/
  ./autogen.sh
  ./configure.sh
  make
  sudo make install
  #+END_SRC

  After compiling and installing emacs we should verify that version ~27.0.50~ is
  installed.

  #+BEGIN_SRC tmate
  emacs --version  
  #+END_SRC

 
* Setup a local emacs pacakge mirror

  To save time we will setup a local mirror for all the LISP files that we need as part of spacemacs.
  Depending on your machine and internet connection it may take some time to download, configure and compile.

  #+NAME: Setup local emacs elpa mirror
  #+BEGIN_SRC tmate
  sudo git clone --depth 1 -b stable https:/github.com/ii/elpa-mirror /usr/local/elpa-mirror
  #+END_SRC

  Setup spacemacs within our home folder.

  #+BEGIN_SRC tmate
  git clone --depth 1 -b stable --recurse-submodules https://github.com/ii/spacemacs.git ~/.emacs.d
  ln -sf ~/.emacs.d/private/local/dot-spacemacs/.spacemacs ~/.spacemacs
  emacs --batch -l ~/.emacs.d/init.el
  #+END_SRC


* Setup mutt email client

  For reading email we ideally use a cli based client for fast searching
  and lightweight mail reading.

  The [[https://gitlab.com/muttmua/mutt/][mutt]] mail client fills these roles well for imap mailboxes.

  The first step to setup mutt is to ensure it is installed.

  #+NAME: Install mutt
  #+BEGIN_SRC shell
  sudo apt-get install mutt 
  #+END_SRC

  After installing mutt we then need to create configuration directories 
  and files.

  #+NAME: Create mutt config files
  #+BEGIN_SRC shell
  mkdir -p ~/.mutt/cache/headers
  mkdir ~/.mutt/cache/bodies
  touch ~/.mutt/certificates
  touch ~/.muttrc
  #+END_SRC

  One configuration folders and files exist we just need to populate our
  user mutt configuration file with a configuration for our particular 
  mail provider.

  The example below utilises the ~bitwarden~ cli utility for secrets to
  ensure these are securely gathered at runtime and not stored in the file.

  #+NAME: Set mutt configuration
  #+BEGIN_SRC shell
  cat > ~/.muttrc << EOF
  set ssl_starttls=yes
  set ssl_force_tls=yes
  set imap_user=`bw get username hosted`
  set imap_pass=`bw get password hosted`
  set from=`bw get username hosted`
  set realname='James Blair'
  set folder=imaps://mail.jamesblair.net
  set header_cache="~/.mutt/cache/headers"
  set message_cachedir="~/.mutt/cache/bodies"
  set certificate_file="~/.mutt/certificates"
  set smtp_url="smtp://`bw get username hosted`@mail.jamesblair.net:587/"
  set smtp_pass=`bw get password hosted`
  set move=no
  set imap_keepalive=900
  set postponed="=Drafts"
  set record="=Sent"
  set imap_passive=no
  set spoolfile=imaps://mail.jamesblair.net/INBOX
  EOF
  #+END_SRC


* Setup environment dotfiles

  Within wsl we can use .dotfiles to further customise our environment. The script
  below restores my versions of key dotfiles automatically.

  #+NAME: Clone and restore the dotfiles
  #+BEGIN_SRC tmate
  git clone ssh://git@gitlab.jamma.life:2224/jmhbnz/tooling.git
  cd /tooling/
  mv * ~/
  #+END_SRC
