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

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"

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?

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.

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

:!mkdir templates
error: can not save universal variables or functions
warning-path: Unable to locate config directory derived from $XDG_CONFIG_HOME: '/nix/store/xabd1qazk33n780qanahmxyqmgb1n83r-neovim-config/fish'.
warning-path: The error was 'Read-only file system'.
warning-path: Please set $XDG_CONFIG_HOME to a directory where you have write access.

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:

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

• 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.

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.
