When I ask Neovim to run a command in the shell with the :! Neovim command, fish complains it has no write access to it's XDG_CONFIG_HOME. That's correct, because I'm hoisting it to a nix store derivation when Neovim starts up:

https://github.com/marcuswhybrow/.nixos/blob/4d44fa8001dc2dbcfd86a7dc8a70e12f89be1fa1/pkgs/neovim/default.nix#L104-L105

Proposed solution: Add to XDG_CONFIG_DIRS, instead of overriding XDG_CONFIG_HOME.

Currently Neovim automatically brings up the completion window selecting the first option. If I hit enter that entry is written to the buffer. If I hit tab, the next entry is written to the buffer.

Instead I want tab to write the current entry to the buffer if it hasn't been already. Currently I have to press enter. But this also executes commands in the context of the neovim command line. And it closes the completion window.

My heart sinks at the thought of creating a custom self-contained package. Creating a custom package isolates the result with it's configuration. But that demands knowing the package dependencies well enough.

• nix profile install is appropriate for trivial cases.
• Modifying ./users/marcus.nix disintegrates logical dependencies that should be packaged together.

Solutions?

• Adjust perceptions of custom packages to start in non-isolation (i.e. using XDG_CONFIG_HOME) and move over time into complete isolation.
  • Indicate isolation by naming convention?
• Support multiple modules in ./users/marcus.nix. Modules prevent disintegration of dependencies. Without modules nix options cannot be repeated, meaning the API becomes the ordering principle.

nix-direnv looks like the best option for speeding up development workflow, by auto-loading the nix shell defined within a project's flake when you cd into the project directory.

It used to show the temperature, now it's always reads "00"

When I try to print a web page, my network printer (AirPrint) is not in the list.

Currently I have 21 Apr 2023 06:37. But what about Fri 21 Apr 2023 06:37? Too cluttered?

• Starship creates my prompt

• It's creates a dynamic representation of the terminal's state

• This currently includes ssh tunneling, git repo status, project languages, shells.

• It can be extended.

• I want to build an extension that tells me that NixOS has updates available.

• I've already build flake-updates which I use in my desktop environment.

• Given a flake.nix it reads the "github:" inputs and uses the GitHub API to see how many updates are outstanding.

• It can render the result to any string you choose.

• I want to output something like that to the terminal too as a Starship plugin.

I bind Print to run my screenshot command. I want to take a screenshot of my waybar, which only appears when Mod is held down. So Mod1+Print must also bind to the screenshot command. Is that the right approach?
