renv

"Rafael's Environment", a bunch of quick & dirty, perhaps awkward hacks tailored for my own usage.

My computing environment based on nix/home-manager.

Introduction

The script renvctl orchestrates part of the process of installing components with home-manager and similar:

λ   ./renvctl help

Pre-Installation

0. Ensure that settings.nix is correct for the environment (e.g. username matches the system, email)
   1. Run ./renvctl home:configure
1. Run ./renvctl check
   • Install the missing dependencies
2. Run ./renvctl deb:install
3. Run ./renvctl nix:install (may need a reboot)
4. Run ./renvctl nix:update
5. Run ./renvctl nix:cache:install
6. (Optional) Run ./renvctl vscode:install
7. (Optional) Run ./renvctl $LANG:install (where $LANG in {ocaml, lean, rust})

Usage

• ./renvctl customise:new to start a new non-persistent customisation file
• ./renvctl home:apply to install all home-manager managed packages
• ./renvctl deb:upgrade to upgrade Debian packages
• ./renvctl nix:update to update nixpkgs

Post-Installation

Load Environment Variables

Append to variables exposed by home-manager to the login config:

echo ". $HOME/.nix-profile/etc/profile.d/hm-session-vars.sh" >> /home/$USER/.profile

Set Fish as Default Shell

Append to shells and then set the shell:

export U=$USER
echo /home/$U/.nix-profile/bin/fish >> "/etc/shells" && chsh -s /home/$U/.nix-profile/bin/fish $U
