• Install Script

This page is the home of my dotfiles. They are written using literate programming in Emacs Org-Mode. The install script installs the dotfiles in their correct places and installs itself as an executable called update-home on the path to allow myself to run the script without having the repository downloaded on my system.

Install Script

It can be run as ./install, so make it explicit what binary to run it with (POSIX shell).

  #!/bin/sh

Save the old log file.

  mv ~/.update-home.log ~/.update-home.log.old

Install the dotfiles repository at ~/.dotfiles if it doesn't already exist.

  if ! test -d ~/.dotfiles; then
      echo Installing dotfiles...
      git clone git@git.sr.ht:~jjanzen/.dotfiles ~/.dotfiles >> ~/.update-home.log
  fi

POSIX shell doesn't have pushd and popd. We do it manually by saving the current path before moving to ~/.dotfiles. Exit if the cd call fails (it shouldn't).

  CWD=$(pwd)
  cd ~/.dotfiles || exit

Stash any existing changes before moving to the main branch and pulling any new changes from the remote.

  {
      git stash
      git checkout main
      git pull --rebase
  } >> ~/.update-home.log

If the update-home executable has changed, replace it and bootstrap into the new one.

  if ! diff ~/.dotfiles/install ~/.local/bin/update-home >> ~/.update-home.log; then
     cp ~/.dotfiles/install ~/.local/bin/update-home || exit 1
     echo Changes have been made to the install script.
     echo Running the new install script.
     ~/.local/bin/update-home
     exit
  fi

Extract each configuration file from its literate .org file into its correct location by running org-babel-tangle on each .org file.

  echo Installing configuration files...
  find -- . -type f -name "*.org" | while read -r file; do
      emacs --batch "${file}" -f package-initialize --eval '(org-babel-tangle)' >> ~/.update-home.log
  done

Install the wallpaper file.

  echo Installing wallpaper...
  cp wallpaper.png ~/.wallpaper

Install any missing fonts by extracting the corresponding tar.gz archive.

  fonts_changed=false
  if ! test -d ~/.local/share/fonts/ComputerModern; then
      echo Computer Modern font missing. Installing...
      tar xf ~/.dotfiles/local/share/fonts/ComputerModern.tar.gz -C ~/.local/share/fonts >> ~/.update-home.log
      fonts_changed=true
  fi
  if ! test -f ~/.local/share/fonts/NFM.ttf; then
      echo Nerd Font Mono font missing. Installing...
      tar xf ~/.dotfiles/local/share/fonts/NFM.tar.gz -C ~/.local/share/fonts >> ~/.update-home.log
      fonts_changed=true
  fi
  if ! test -d ~/.local/share/fonts/SauceCodePro; then
      echo Source Code Pro Nerd Font missing. Installing...
      tar xf ~/.dotfiles/local/share/fonts/SauceCodePro.tar.gz -C ~/.local/share/fonts >> ~/.update-home.log
      fonts_changed=true
  fi

If any missing fonts were installed, update the font cache.

  if [ $fonts_changed = true ]; then
      echo Updating the font cache...
      fc-cache -f >> ~/.update-home.log
  fi

Move the user back to where they came from.

  cd "${CWD}" || exit
