* 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


  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
  # Install basic utilities
  sudo apt-get install -y git locales curl wget xclip tmux net-tools less wget htop screenfetch
  
  # Install pre-requisites for compiling emacs
  sudo apt-get install -y make gcc libgnutls28-dev libtinfo-dev
  
  # Install dpkg management tools
  sudo apt-get install -y software-properties-common apt-transport-https ca-certificates
  #+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 then install the Google Cloud SDK & kubectl: 
  sudo apt-get update && sudo apt-get install google-cloud-sdk kubectl
  #+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 iimacs

  A key component in our environment is the ii version of emacs. The section below will setup
  emacs version ~26.3~ and then iimacs on top.

  #+NAME: Download and extract emacs source
  #+BEGIN_SRC tmate
  cd ~/Downloads/
  wget https://mirror.ossplanet.net/gnu/emacs/emacs-26.3.tar.xz
  tar xf emacs-26.3.tar.xz
  cd emacs-26.3.tar.xz
  #+END_SRC


  #+NAME: Compile and install emacs
  #+BEGIN_SRC tmate
  ./configure --without-x
  sudo make -j `nproc`
  sudo make install
  #+END_SRC

  After compiling and installing emacs we should verify that version ~26.3~ is
  installed.

  #+BEGIN_SRC tmate
  emacs --version  
  #+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/
  cp .* ~/
  #+END_SRC
