These dotfiles make my life slightly more convenient. Not promising they’ll do the same for yours though. 😉

My configuration is currently managed with home-manager for the better DX or UX. Before using home-manager, I manually managed symlinks from my config directory to this dotfiles repo. The use of GNU Stow was considered for a brief moment until I realized that Stow was written in Perl and I came to terms with my unwillingness to have a critical part of my stack based on tooling that brings me no joy 🙊 (on account of my troubled personal history with Perl).

1. Ensure Nix is installed as outlined in https://github.com/NixOS/nix#installation

   curl -L https://nixos.org/nix/install | sh
       

2. Optionally install homebrew as outlined on https://brew.sh in case you want to manage some of your brew packages with Nix as well. Note that you may not need to manually add homebrew to your path if you use nix-darwin as the homebrew activationScript will take care of it.
3. Optionally install Rosetta 2 for the case where it may be necessary since tools like Docker may rely on for some of their capability.

   softwareupdate --install-rosetta
       

4. Setup nix-darwin and apply the configuration as outlined in https://github.com/LnL7/nix-darwin/#step-2-installing-nix-darwin

   nix run nix-darwin -- switch --flake . --show-trace
       

   On systems, where darwin-rebuild has already been installed, run the following command instead:

   darwin-rebuild switch --flake .
       

   In case of error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override errors, try to run:

   nix --extra-experimental-features nix-command --extra-experimental-features flakes run nix-darwin -- switch --flake . --show-trace
       

5. Update the nix flakes using

   nix flake update
       

   and if you just want to upgrade packages managed by brew, run:

   brew upgrade
       

1. In order to debug the config enter a Nix REPL and inspect the inputs and outputs by using tab-completion on the variables inputs and outputs after loading the Flake.

   Enter the REPL with the following command:

   nix repl
       

   Bring the input and output variables into the REPL scope by loading the Flake as follows:

   :lf .
       

   See relevant help information by running:

   :?
       

See the nix-darwin configuration section for configuration/implementation details.

On my old MacBook Pro, I started by installing and using home-manager first before deciding to use nix-darwin. This has created some nix-related configuration on my machine that nix-darwin did not fully overwrite when I applied that change. Because of this imperative change nonesense, I had latent QEMU and Emacs packages in my nix path (observeable through running tree -L 2 ~/.nix-profile).

I attempted to resolve this by removing the home-manager package from my profile:

> nix profile list

3 - - /nix/store/7z9x0izk35yzggjhlnvsmv3y4sahijmh-home-manager-path

and then rebuilding the config.

With this, I believe I messed up my config even more, so I had to uninstall nix-darwin altogether https://github.com/LnL7/nix-darwin#uninstalling and then remove all nix-related folders as outlined in https://nixos.org/manual/nix/stable/installation/uninstall#macos.

sudo rm -rf /etc/nix /var/root/.nix-profile /var/root/.nix-defexpr /var/root/.nix-channels ~/.nix-profile ~/.nix-defexpr ~/.nix-channels

After this, I restart the installation process.

Reading https://gist.github.com/jmatsushita/5c50ef14b4b96cb24ae5268dab613050?permalink_comment_id=4054744#gistcomment-4054744 led me to believe that the removal of ~/.nix-profile may have broken my system further but then it seems that nix-darwin uses global profiles instead of user-based profiles, which suggests that the existence of ~/.nix-profile may have been a remnant of my pre-nix-darwin use of home-manager. For now it seems that enabling the emacs service in nix-darwin does not immediately expose a CLI-accessible command. I’ve resorted to enabling the service along with installing emacs as a systemPackage but I have to first confirm if the emacs service alone yields a system that exposes the emacs command in a standard shell.

On a completely fresh macOS machine you may encounter ls: .: Operation not permitted errors if Terminal has not been granted prior access to the full disk.

Navigate to the “Full Disk Access” setting and enable access for the Terminal.

The use of home-manager is pretty straightforward especially with the convenient nix shell and the Makefile that make usage even easier. The general idea is as follows:

• shell.nix defines a shell environment that contains all packages needed to install or apply a configuration. The packages include niv which helps us manage versions of our packages, home-manager which actually manages our home environments (hence the name) and and some utils.
• Makefile contains some rules to simplify how we call home-manager inside of the nix-shell since it effectively reduces the UX down to make or make test calls as opposed to home-manager -f ./home.nix -v -n build and home-manager -f ./home.nix switch respectively (which you don’t want to have to remember 🤷🏿‍♂️).

Typical use will be as follows:

1. Enter the nix-shell using nix-shell --pure
2. Configure your personal.nix to specify home.username, home.homeDirectory and home.stateVersion for your system
3. Optionally, update niv-managed packages by running niv update to update the sources files (nix/sources.json and nix/sources.nix), as demonstrated below:

   niv update home-manager
   niv update nixpkgs
       

4. Run make test to test the home-manager configuration or make to install the configuration
5. Optionally, if package update step was completed (step 2 above), commit the changes made to the niv sources files
6. Profit 💰

💡 Note that home-manager generated configuration files will be written somewhere to ~~/.config~, e.g.: ~~/.config/git/config~ for git.

We use niv to manage our dependencies and manage this throught the pkgs-bleeding which we set up in let blocks of shell.nix and common.nix:

nixpkgs-bleeding-src = sources."nixpkgs-bleeding";
pkgs-bleeding = import nixpkgs-bleeding-src { };

pkgs-bleeding.niv
pkgs-bleeding.nixVersions.nix_2_13

For home-manager to work, we define a nix-shell that we creates a controlled environment for our Makefile to work.

# Tangled from README.org
# From https://github.com/ryantm/home-manager-template

let
  sources = import ./nix/sources.nix;

  nixpkgs-src = sources."nixpkgs";
  pkgs = import nixpkgs-src { };

  hm-src = sources."home-manager";
  nur-src = sources."NUR";

  <<common-packages-let>>

in
pkgs.mkShell rec {
  name = "home-manager-shell";

  buildInputs = with pkgs; [
    <<shell-build-inputs>>
  ];

  <<shell-hook>>
}

The build inputs for our shell are:

<<common-packages>>
(import hm-src { inherit pkgs; }).home-manager
cacert # to resolve CA cert issue
hello
git
ncurses # to resolve tput issue
which

For the shell environment to be portable enough to run on both Linux and Darwin (macOS) systems, we define a shell hook that will export a few environment variables into existence depending on the system.

export NIX_PATH="nixpkgs=${nixpkgs-src}:home-manager=${hm-src}:NUR=${nur-src}"
export HOME_MANAGER_CONFIG=${system}

The above snippet is a bit of a cheat because we’ve formatted it as bash but some of the variable expansion work is being done by Nix and not Bash. 😅 We wrap the shell expressions into the following Nix statement to set system (see the cheat in the snippet above) and we basically pull in the sources through our niv sources file which is defined at the start of our shell.nix file.

shellHook = with pkgs; let
  system = (
    if stdenv.isLinux
    then "./home-linux.nix"
    else
      (if stdenv.isDarwin
      then "./home-darwin.nix"
      else "./home.nix")
  );
in
''
  <<shell-hook-src>>
'';

With all of this out of the way, running make should just drop us into a Nix shell with everything preconfigured and then run some incantation of home-manager switch in order to switch our home-manager-managed, pun intended, environment.

Enter a REPL by entering the nix-shell first (to set up the env var NIX_PATH) and then run the following statement to obtain a reference to the home-manager configuration:

hm = import <home-manager/modules> { inherit pkgs; configuration = ./home-linux.nix; }

# Tangled from README.org
{ config, lib, pkgs, ... }:

# TODO: Config mutt
let
  inherit (pkgs) stdenv;

  sources = import ./nix/sources.nix;

{
  imports = [

  ]
  ++ (pathIfExists ./personal.nix);

  home.packages = [
    <<common-packages>>
    <<desktop-packages>>
  ];

  home.file.".direnvrc".source = config.lib.file.mkOutOfStoreSymlink ./direnv/direnvrc;

  #home.file.".profile".text = ''
  #  PATH=${toString ./bin}:$HOME/.nix-profile/bin:$PATH
  #  export PATH
  #'';

  home.sessionPath = [
    (toString ./bin)
  ];

  nix = {
    package = pkgs-bleeding.nixVersions.nix_2_13;

In order to simplify screen management, we can use the autorandr utility.

For the first time using a configuration, we use the arandr utility to graphically align the screens in the formation that we want after which we can save and name the configuration using the following command (where CONFIGNAME is the name that we want to save the configuration as):

autorandr --save CONFIGNAME

A configuration can be autoloaded by running the following command:

autorandr --change

⚠️ With the autorandr tool, we have to plug screens into the same ports as we used when configuring the setup. In the case of my newer laptop where I have a bunch of USB C ports with the risk of pluggin monitors in different configurations between docking attempts, I just connect the monitor in every likely configuration, configure my setup with arandr and then save it with autorandr --save to ensure that autorandr will have seen that configuration before. 😉

programs.autorandr = {
  enable = true;
};

The slock package is a simple X screen locker by the suckless.org team.

Installing slock through systemPackages causes the unable to disable the OOM killer. Make sure to suid or sgid slock, see https://nixos.wiki/wiki/Slock.

We therefore install slock in the nixos-configuration.

screen-locker = {
  enable = true;
  lockCmd = "/run/wrappers/bin/slock";
};

The tedious way basically requires one to make symlinks from the needed locations into this dotfiles repository. There are a number of ways how one can simplify this experience ranging from manually symlinking everything that you would need all the way up to using a home-manager alternative like GNU Stow to manage these symlinks for you (and minimize the toil on your end).

This is a listing of the symlinks that I could track in my home directory right before moving over to home-manager. I may have missed some, but largely this covers much of what I have packaged in this repository so it should be relatively complete.

For developer tooling, we define our userName and userEmail which we will rely on in configuring git, for example.

userName = "David Asabina";
userEmail = "[email protected]";

We all have parts of our configs that are for our eyes only and the personal.nix file can be populated to contain sensitive and private parts of your configuration. This home-configuration will load a personal.nix file if found so the use of this file is optional (your configuration should work without it).

Observe the snippet below for an example of a valid personal.nix file.

{ config, pkgs, lib, options, ... }:

{
  # Home Manager needs a bit of information about you and the
  # paths it should manage.
  home.username = "vidbina";
  home.homeDirectory = "/home/vidbina";

  # This value determines the Home Manager release that your
  # configuration is compatible with. This helps avoid breakage
  # when a new Home Manager release introduces backwards
  # incompatible changes.

  # You can update Home Manager without changing this value. See
  # the Home Manager release notes for a list of state version
  # changes in each release.
  home.stateVersion = "21.05";

  home.packages = [ ];
}

Note that the same configuration above is adapted for macOS by setting home.homeDirectory to a valid macOS home path like /Users/vidbina.

On macOS, nix-darwin provides the most batteries included nix experience. We can manage services (through launchd), home-manager and homebrew all through a nix configuration.

# This is a nix-darwin config
{ pkgs, lib, inputs, config, username, ... }: {
  imports = [
    # import modules into our nix-darwin config
    <<nix-darwin-imports>>
    ./emacs/nix-darwin.nix
    ./system/darwin
  ];

  # List packages installed in system profile. To search by name, run:
  # $ nix-env -qaP | grep wget
  environment.systemPackages = with pkgs; [
    <<nix-darwin-packages-common>>
  ] ++ (if system == "aarch64-darwin" then [
    # ARM-only packages
    <<nix-darwin-packages-arm>>
  ] else [
    # Intel-only packages
    <<nix-darwin-packages-intel>>
  ]);

  environment.interactiveShellInit = lib.strings.concatStrings [
    <<nix-darwin-interactive-shellinit>>
  ];

  # General nix-darwin settings
  <<nix-darwin>>
}

Read the Apple Daemons and Service Programming Guide for some basic information on how to work with launchd. Keep in mind that launchd isn’t systemd and sucks in the sense that starting/stopping services doesn’t seem to do the obvious things that their names imply and as one has grown familiar to with systemd.

Furthermore read https://www.launchd.info/ for more information on the launchd system. I have for a long time misunderstood it as an init system hut it is more of a job manager.

Intel-only packages are listed separately such that we can use them on the macOS machine that still has a x86-based Intel chip but avoid trying to install them on ARM-based Apple machines.

gdb
ghidra-bin

It follows that the amount of Intel-only packages will decrease as developers make their applications more readily available.

Install apps from the Apple App Store through the mas CLI tool for which the nix-darwin homebrew config provides the =masApps= attribute.

Apps need to already be in a user’s Purchased list before mas can install them. For any new tools, just make sure that you install it on one machine at least manually in order to add it to your Purchased list as documented in GH mas-cli issue 85. In my case, I didn’t even complete the installation, I just started it to add it to the list and then prematurely stopped it in order to continue the installation through nix-darwin.

Keep in mind to authorize your device as documented in https://support.apple.com/en-us/HT201251 and which can be done through the following steps:

• Open Apple Music
• Navigate to Account > Authorisations > Authorise this computer
• provide credentials to Apple account.

You can review your current computer’s authorisation status by opening the App Store app and opening the Account Settings modal.

Computer authorisation status did not have any bearing on this issue but it seems a good practice to keep ocassionally verify that all the authorised devices in an account are still in your possession.

nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [

We will be tangling this literate configuration into the needed dev.nix file.

./dev.nix

For starters, we stub the general structure of the nix file and define the <<nix-devtools>> reference for us to direct our tool-specific configs into.

# Tangled from README.org
# Please modify by editing README.org and re-tangling to generate this nix file.
{ config, lib, pkgs, options, ... }:

{
  <<nix-devtools>>

  home.packages = [
    <<dev-packages>>
  ] ++ (if pkgs.stdenv.isLinux then [
    <<dev-packages-linux>>
  ] else [ ]);
}

As an example, you can observe how we direct some comments into the previously defined reference. In the following sections, we will use this mechanism to tangle (basically “write”) into parts of the dev.nix file.

# Tangling individual dev tools through nix-devtools noweb reference

We tangle the git-related configuration into dev.nix but if you want to manually set things up, check out the manual git instructions.

ln -s ./git/gitconfig ~/gitconfig

The global excludes file defaults to ./config/git/ignore so we’re linking our ignore go-to into this path for convenience.

ln -s ./git/ignore ~/.config/git/ignore

programs.git = {
  enable = true;
  <<nix-devtools-git>>
};

For convenience we define git/ignore which we want to automatically want to honor in every repo. Based on the instructions in man gitignore we stub the XDG_HOME_CONFIG/.config/git/ignore and the ~/.gitignore files to reflect the content of git/ignore.

# Set global gitignore
home.file = {
  ".config/git/ignore".source = config.lib.file.mkOutOfStoreSymlink ./git/ignore;
};

We want LFS enabled.

lfs.enable = true;

Let’s opt for naming our default branch “main”, using nvim as our editor, using gpg2 are our GPG tool and setting git up to send patches by mail.

extraConfig = {
  init = {
    defaultBranch = "main";
  };

  core = {
    editor = "nvim";
  };

  gpg = {

I have issues with my touchpad often enough and also have issues with Chromium hanging here and there. It’s time that I learned to dig into some of the Linux innards and do some good kernel watching.

See https://lwn.net/Articles/658948/

   xinput --list
       

2. Show properties for device

  evemu-record /dev/input/event13 touchpad-debug.evemu
      

Recorded some data while I was observing the choppy behavior

evemu-record /dev/input/event13 touchpad-debug.evemu

Then replayed the recording to confirm choppiness in the recorded output

evemu-play touchpad-debug.evemu

According to ChatGPT:

If the recording from evemu-record is already choppy, the problem is likely at a lower level than libinput. Libinput processes the events given by the kernel, so if the kernel events are choppy, libinput will also see choppy data.

Here are some steps you can take to debug the issue:

• Check the Kernel Version: As mentioned before, the issue may lie within the kernel. If you’re using an old version of the kernel, consider updating it.
• Check for Hardware Issues: If possible, test the trackpad in a different operating system (like Windows or a different Linux distribution) to rule out hardware issues.
• Check for Dropped Events: The evemu-record tool records events as they come from the kernel. If events are being dropped, that might cause choppy input. Use the evtest tool to check if any events are being dropped.
• Check for Firmware Issues: It might be possible that your laptop’s firmware is causing issues. Check the manufacturer’s website for any firmware updates.
• Check dmesg for Errors: Run dmesg | grep -i error to check for any hardware errors related to the touchpad.
• Contact the libinput Community: If you’re unable to resolve the issue yourself, consider reaching out to the libinput community for help. They might be able to provide more specific guidance.
• Remember, always be careful when upgrading the kernel or firmware, or changing system settings. Always backup your data before making significant changes to your system.

Reading https://www.dell.com/support/kbdoc/de-de/000150104/precision-xps-allgemeine-problemloesung-f-uuml-er-touchpad-maus-in-ubuntu and concluding that dmesg needs to be monitored for kernel events

Searching for DLL0945:00 04F3:311C on Google yields https://www.dell.com/community/XPS/XPS-15-9510-Touchpad-Intermittent-touchpad-lag/td-p/8012567/page/4 where the following comment is posted:

I can also reproduce that this is related to the palm rejection on the side of the touchpad. Usually the cursor does not move when I move the finger on the very right side of the touchpad. Every time the cursor is laggy, the palm rejection does not work and I can move the cursor by touching the pad on the very right side.

I also tried out the mtouch drivers instead of libinput but the problem persists. so I suppose that the problem is related to the firmware of the touchpad.

Visual Studio Code is unfree software and needs to be added to the list of unfree packages that we want to tolerate:

"vscode"

Our vscode configuration declaratively manages soem extensions, keybindings and user settings:

programs.vscode = {
  enable = true;
  extensions = with pkgs.my-vscode-extensions.vscode-marketplace; [
    <<vscode-extensions>>
  ];
  keybindings = [
    <<vscode-keybindings>>
  ];
  userSettings = {
    <<vscode-settings>>
  };
};

We get our vscode extensions from the nix-community nix-vscode-extensions package which we alias to the reference my-vscode-extensions for internal use:

my-vscode-extensions = inputs.vscode-extensions.extensions.${pkgs.system};

The extensions that we are interested in are the following:

bbenoist.nix
be5invis.toml
github.copilot
github.copilot-chat
hediet.vscode-drawio
mkhl.direnv
ms-azuretools.vscode-docker
ms-python.python
ms-vscode-remote.remote-containers
tomoki1207.pdf
vscode-org-mode.org-mode
vscodevim.vim

The keybindings that we want are as follows:

{
  "key" = "ctrl+tab";
  "command" = "workbench.action.nextEditorInGroup";
}
{
  "key" = "ctrl+shift+tab";
  "command" = "workbench.action.previousEditorInGroup";
}

In order to enable long-presses to register multiple entries we need the ApplePressAndHoldEnabled OSX setting, otherwise, we have to manually depress a key multiple times in order to have multiple entries.

defaults.CustomUserPreferences = {
  "com.microsoft.VSCode" = {
    "ApplePressAndHoldEnabled" = false;
  };
};

Define parts of the VsCode-specific fields are defined in the JSON format as follows:

"editor.cursorSurroundingLines" = 8;

# https://code.visualstudio.com/docs/editor/extension-marketplace#_can-i-stop-vs-code-from-providing-extension-recommendations
"extensions.ignoreRecommendations" = true;
"extensions.showRecommendationsOnlyOnDemand" = true;

# https://code.visualstudio.com/docs/editor/extension-marketplace#_can-i-stop-vs-code-from-providing-extension-recommendations

home.file.".emacs.d".source = config.lib.file.mkOutOfStoreSymlink "${config.home.homeDirectory}/Code/vidbina/dotfiles/emacs";

At the moment we import our nix configs for Emacs into our configuration-darwin.nix file and for Linux we haven’t really considered how to do this since we don’t actively use Linux atm. We’ll have to fix this at some point.

For now, I symlink ~/.xmonad to ~/src/vidbina/xmonad-config and run xmonad --recompile to produce the Xmonad binary.

Navigate to Syncthing portal to configure your setup. As per [2022-05-05 Thu 12:08], the syncthing service in home-manager is only declarative to the extend of turning it on and providing extra CLI options to start the service with.

Consult the Getting Started guide to learn how to set it up “imperatively” (i.e.: setting up peers and generating their IDs and copying the needed information over to the other syncthing peers to establish connections) through the portal.

services.syncthing = {
  enable = true;
};

[2024-02-07 Wed] On macOS, the syncthing service isn’t running which was confirmed by running:

launchctl list org.nix-community.home.syncthing

where the output is

{
	"LimitLoadToSessionType" = "Aqua";
	"Label" = "org.nix-community.home.syncthing";
	"OnDemand" = true;
	"LastExitStatus" = 19968;
	"Program" = "/nix/store/rnigg5xf6n2jxda3ivscrn0yzw474dq4-syncthing-1.26.1/bin/syncthing";
	"ProgramArguments" = (
		"/nix/store/rnigg5xf6n2jxda3ivscrn0yzw474dq4-syncthing-1.26.1/bin/syncthing";
		"-no-browser";
		"-no-restart";
		"-logflags=0";
	);
};

which seems at odds with the nix definition for syncthing

launchd.agents.syncthing = {
  enable = true;
  config = {
    ProgramArguments = syncthingArgs;
    KeepAlive = {
      Crashed = true;
      SuccessfulExit = false;
    };
    ProcessType = "Background";
  };
};

as KeepAlive is defined in the nix config, but missing in the observed launch output, furthermore OnDemand isn’t mentioned at all in the nix config. 🤷🏿

It seems that the OnDemand option is a pre macOS 10.5 key which has been superceded by KeepAlive.

Just to confirm, Syncthing really isn’t running, I have checked the process list for a corresponding entry:

ps aux | grep syncthing

Trying to start syncthing through

launchctl start org.nix-community.home.syncthing

yields status 134 (SIGABRT) and 139 (SIGSEGV). Retrying with sudo fails with status 3.

Attempts to kickstart with

launchctl kickstart gui/501/org.nix-community.home.syncthing

also fail with 139: Service cannot presently execute but of course I don’t have any freaking logs.

😕 I just ran the launchctl list and ps commands on my personal MacBook and found that syncthing is running as a daemon there. Perhaps I need a system restart. I recall that starting/stopping logic with launchd is quite different in terms of UX to systemd and likely the start/stop commands just don’t do the same thing.

As a fallback, just start syncthing through a terminal with the temporary added benefit of having a log/trace of Syncthing’s actions. This needs further exploration.

A deeper dive, leads me through https://www.launchd.info/ which outlines where the different files for job definitions are stored. For me ~/Library/LaunchAgents/org.nix-community.home.syncthing.plist seems to match the definition in the home-manager codebase, unlike the output I was seeing from launchctl list earlier.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>KeepAlive</key>
	<dict>
		<key>Crashed</key>
		<true/>
		<key>SuccessfulExit</key>
		<false/>
	</dict>
	<key>Label</key>
	<string>org.nix-community.home.syncthing</string>
	<key>ProcessType</key>
	<string>Background</string>
	<key>ProgramArguments</key>
	<array>

		<string>-no-browser</string>
		<string>-no-restart</string>
		<string>-logflags=0</string>
	</array>
</dict>
</plist>

Perhaps the new job definition has simply not been loaded, which would be a failing of the darwin-rebuild switch run we did earlier. So, for next time, I should remember to try the following:

sudo launchctl load ~/Library/LaunchAgents/org.nix-community.home.syncthing.plist
sudo launchctl enable gui/501/org.nix-community.home.syncthing

but for now, I just try a restart and see what happens. 🤞🏿

Especially for things link mail indices and Org-roam databases, I may need to do this.

Note that the content of the object file has a different init func:

nm -gD /run/opengl-driver/lib/dri/iHD_drv_video.so | grep __vaDriverInit

Searching through the other files object files in file:/run/opengl-driver/lib/dri, I noticed that a few do list a v1.0 init function.

nm -gD /run/opengl-driver/lib/dri/nvidia_drv_video.so | grep __vaDriverInit

So, we need to clean up some of the drivers if Chromium is trying to resolve which init function to calld dynamically.

Also vainfo communicates the version to be beyond 1.0, 1.17 to be precise.

DAWN Info

<CPU> Vulkan backend - SwiftShader Device (Subzero)
[Default Toggle Names]
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.
disallow_unsafe_apis: http://crbug.com/1138528: Produces validation errors on API entry points or parameter combinations that aren't considered secure yet.
use_vulkan_zero_initialize_workgroup_memory_extension: https://crbug.com/dawn/1302: Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan extension VK_KHR_zero_initialize_workgroup_memory is supported.
[WebGPU Forced Toggles - enabled]
disallow_spirv: https://crbug.com/1214923: Disallow usage of SPIR-V completely so that only WGSL is used for shader modules. This is useful to prevent a Chromium renderer process from successfully sending SPIR-V code to be compiled in the GPU process.

Note how NixOS/nixpkgs#211408 outlines a fix regarding graphics switching/offloading:

DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1=1

We set this through the home.sessionVariables option, so we can just run chromium to keep things simple:

⚠️ In order to get the extensions in Firefox to work, you may have to first manually enable the extensions.

programs.firefox = {
  enable = true;

  <<browser-firefox-profiles>>
};

# NOTE: Extensions need firefox.profiles to be defined
profiles.personal.extensions =
  # https://nur.nix-community.org/repos/rycee/

    <<browser-firefox-extensions>>

Tridactyl is the extension introducing the vim bindings into Firefox. It will hijack the body of your new tabs which can bit a bit disruptive to your workflow as it will present a Tridactyl start page which is visually quite busy therefore running :set newtab about:blank to clear the body of the new tab can improve the UX and run :set theme dark to switch to a dark theme if new tabs are blasting you with white light.

Remember that <C-,> (as described in the Tridactyl documentation which would be C-,= in Emacs bindings notation or more simply but =Ctrl + =,​=) is the Tridactyl escape hatch that gets you into a part within the page view of the browser where you can use the vi-like bindings to navigate or do this.

💡 This is convenient because loading some pages will leave the focus on the URL bar or the search bar and tabbing through may be a tedious way to get to the page view.

Remember that Shift + Insert (or Ctrl + Alt + Escape but I’m refusing to learn that one because it is quite a dragon of a maneuver to efficiently pull of) will toggle to ignore mode in which all keypresses are passed-through to the web application.

💡 This is convenient for applications that have their own bindings that may conflict with Tridactyl.

Use / to enter a search query and use Ctrl + g or Ctrl + G to cycle through search results.

💡 The search cycling binding is a bit differnet to what vi-bindings users may expect so just pay attention to keep C-g and C-G (expressed in Emacs notation) within (muscle) memory.

GitHub wraps mermaid diagrams in a div with the .mermaid class:

div.mermaid svg#diagram rect.er.entityBox {
  fill: transparent !important;
}

More generally and for the Mermaid Live editor the following applies added up top:

<<darkreader-mermaid>>

We fix the navigation controls for embedded mermaid diagrams by setting the fill and background clors on the control-panel buttons:

div.mermaid-viewer-control-panel .btn {
  fill: var(--darkreader-neutral-text);
  background-color: var(--darkreader-neutral-background);
}

For the ER diagrams:

svg g rect.er {
  fill: var(--darkreader-neutral-background) !important;
}
svg g rect.er.entityBox {
  fill: var(--darkreader-neutral-background) !important;
}
svg g rect.er.attributeBoxOdd {
  fill: var(--darkreader-neutral-background) !important;
}
svg g rect.er.attributeBoxEven {
  fill-opacity: 0.8 !important;
  fill: var(--darkreader-selection-background);
}
svg rect.er.relationshipLabelBox {
  fill: var(--darkreader-neutral-background) !important;
}

For the Flow diagrams:

svg g g.nodes rect, svg g g.nodes polygon {
  fill: var(--darkreader-neutral-background) !important;
}

For Gantt diagrams:

svg g rect.task {
  fill: var(--darkreader-selection-background) !important;
}

For Sequence diagrams:

svg line.messageLine0, svg line.messageLine1 {
  stroke: var(--darkreader-neutral-text) !important;
