nix-shell $HM_PATH -A install

a handful of opinionated utilities to facilitate working in a hybrid, (mostly) nix-managed development environment

source bash/nix_shortcuts.sh in bash/zsh to add e.g. these functions:

read-shortcuts <path-to-shell-script>

get overview of functions/aliases

shortcuts

print full overview from previously read scripts

create-nix-shell-skeleton

create a basic helper-enabled shell.nix file

create-nix-flake-skeleton

create a basic helper-enabled flake.nix file

• loads the helper nix functions (flake-helpers.nix) from a pinned commit of this repo
• shortcuts utilities from nix_shortcuts.sh (not printed)
• shortcuts from jsonnet_shortcuts.sh (not printed)
• shortcuts from package-jsonnet-composition.nix.sh (not printed)
• source and run echo-shortcuts for scripts you add to the includeScripts array
• add the shellHook of the flake to echo-shortcuts

the motivation behind this per-projects shell shortcuts organization is introduced here

vagrant init nixos/nixos-18.03-x86_64
vagrant plugin install vagrant-disksize

probably skip this; the provisioner is not as reliable as directly running nixos-rebuild switch

vagrant plugin install vagrant-nixos-plugin

1. enable

   nixpkgs.config.allowUnfree = true; # for nixos
       

   in file:/etc/nixos/configuration.nix; for non-nixos you should set

   allowUnfre = true;
       

   in file:~/.config/nixpkgs/config.nix

2. NIXPKGS_ALLOW_UNFREE=1 nix-env -qa | grep vscode
3. NIXPKGS_ALLOW_UNFREE=1 nix-env -i vscode

one-shot command: setxkbmap -option "ctrl:nocaps"

via xmodmap with mapping Alt_R to mod3

clear mod3
remove mod1 = Alt_R
add mod3 = Alt_R

xfconf-query -c xsettings -p /Gtk/KeyThemeName -s Emacs

nix-shell -p alsaLib pkgconfig x11 xorg.libXrandr xorg.libXinerama xorg.libXScrnSaver --run 'xmonad --recompile'
nix-shell -p alsaLib pkgconfig x11 xorg.libXrandr xorg.libXinerama xorg.libXScrnSaver --run 'xmonad --restart'

xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -t string -sa xmonad

running e.g. firefox from the command line spits out a lot of warnings. in particular, theme warnings can be fixed with:

export GTK_THEME=Adwaita firefox

1. link setup/nix to $HOME/.nixpkgs
2. nix-env -i my-custom-nixpkgs
