Packages

Home-manager "packages" are simply binaries that are placed on the path, without any attached configuration. The code blocks in this section contain package lists that go under the packages section above.

SBCL is the current leading open-source common lisp compiler. It requires any libraries you want to be availble to be installed using withPackages. Many lisp projects I work on have this overridden in a nix devshell I think I'd also like to use it for scripting / exploratory development, though, so I'm installing it globally with a useful set of libraries. I should curate this somewhat carefully so it doesn't get carried away…

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      rlwrap
      (sbcl.withPackages (ps: with ps; [
        alexandria
        cl-markup
        cl-mock
        clack
        clack-handler-woo
        dbi
        defstar
        dexador
        fare-csv
        group-by

rage is a rust implementation of age. It implements a simple system for generating public / private encryption keys, and encrypting / decrypting files with those keys. age-plugin-yubikey, as the name implies, allows generating and storing age keys on a Yubikey. rage is required over age when using age.el, because it supports pinentry. That allows it to prompt for yubikey pins using a dialog, rather than a command line prompt.

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      rage
      age-plugin-yubikey
      yubikey-manager
    ];
  }

dust, fd, ripgrep, and xh are rust re-implementations of a few longtime Linux command-line tools. They boost better speed, or simply more streamlined features.

Command	Original
dust	du
fd	find
ripgrep	grep
xh	curl

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      dust
      fd
      ripgrep
      tokei
      xh
    ];
  }

ledger is how I manage my budget. It's a plain-text accounting tool that's really awesome.

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      ledger   
    ];
  }

nil is an LSP server for nix files.

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      nil   
    ];
  }

Magic Wormhole is a quick-and-easy way to securely transfer a file or directory between any two computers in the world, assuming that you have an out-of-band way to communicate a passphrase between them. Once installed, the actual command is wormhole.

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      magic-wormhole   
    ];
  }

These are the other programs I have installed globally. A few (like awscli, mysql-client, etc.) are still Redbook-specific; ideally I'd find another way to install them.

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      openssh
    ];

   fonts.fontconfig.enable = true;
  }

These programs require a full desktop environment:

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      google-chrome
      nerd-fonts.jetbrains-mono
      nerd-fonts.symbols-only
      (iosevka-bin.override { variant = "Aile"; })
      (iosevka-bin.override { variant = "Etoile"; })
      (iosevka-bin.override { variant = "SGr-IosevkaTermSS14"; })
      nerd-fonts.symbols-only
      keymapp
      proton-pass
      wireshark
    ];
  }

  {pkgs, ...}:
  {
    home.packages = with pkgs; [
      linear
      notion-app
      (slack.overrideAttrs {
        version = "4.50.143";
        src = pkgs.fetchurl {
          url = "https://downloads.slack-edge.com/desktop-releases/mac/arm64/4.50.143/Slack-4.50.143-macOS.dmg";
          hash = "sha256-f5oYi8NPKXWpDcowFYMUjptbQs4V9hK2bm1TuaQeJn0=";
        };
      })
      teams
    ];
  }

Program Configurations

This section contains applications whose config files will be generated by Home Manager. Home Manager calls these "programs" (as opposed to "packages", which are just binaries to put on the path).

Simple Programs

Although Home-Manager generates config files for these programs, they don't need their own dedicated configuration. I'm not sure what benefit there is to enabling jq as a Home Manager program, rather than just as an available package, but there doesn't seem to be a downside.

  {
    programs = {
      bash.enable = true;
      gh.enable = true;
      home-manager.enable = true;
      jq.enable = true;
      lazygit.enable = true;
      zoxide.enable = true;
    };
  }

Bat

bat is a less alternative that performs syntax highlighting for a variety of languages. It also provides syntax-highlighting versions of a few other commands. It's honestly not incredibly useful, but still nice to have.

  {
    programs.bat = {
      enable = true;
      config.style = "numbers";
    };
  }

Comma

  {
    programs.nix-index.enable = true;
    programs.nix-index-database.comma.enable = true;
  }

Direnv

direnv allows loading per-project paths as I navigate to their directories on the command line. I leverage this with the emacs envrc package.

  {
    programs.direnv = {
      enable = true;
      nix-direnv.enable = true;
    };
  }

Eza

eza is an ls replacement that offers icons, colors, and some easier command-line options.

  {
    programs.eza = {
      enable = true;
      enableBashIntegration = true;
      enableZshIntegration = true;
      icons = "auto";
    };
  }

Fzf

fzf offers a variety of fuzzy finders right from the shell. I haven't been using this, so I'll turn it off for now.

  {
    programs.fzf = {
      defaultCommand = "fd --type f";
      fileWidgetCommand = "fd --type f";
      fileWidgetOptions = ["--preview" "'bat --color=always --style=numbers --line-range=:500 {}'"];
      changeDirWidgetCommand = "fd --type d";
      tmux.enableShellIntegration = true;
    };
  }

Git

We all know what git does.

  {
    programs.git = {
      enable = true;
      settings.user.name = "Joe Frikker";
      settings.user.email = "joe@redbookcattle.com";
      settings.github.user = "joe@redbookcattle.com";
      settings.merge.conflictstyle = "zdiff3";
    };

    programs.delta = {
      enable = true;
      enableGitIntegration = true;
    };
  }

Helix

The best text editor ever? Heresy!

  {
    programs.helix = {
      enable = true;
      defaultEditor = true;

      settings.editor = {
        auto-format = false;
        auto-pairs = false;
        auto-save.after-delay.enable = true;
        auto-save.after-delay.timeout = 1000;
        cursorline = true;
        idle-timeout = 0;
        rulers = [120];
        text-width = 100;
        lsp.goto-reference-include-declaration = false;
        cursor-shape.insert = "bar";
        smart-tab.supersede-menu = true;
        whitespace.render.newline = "all";
      };

      settings.keys.normal.space = {
        space = "file_picker";
        "," = "buffer_picker";
        # b = "@:sh wezterm cli spawn --cwd . -- tig blame <C-r>%<ret>";
      };


      languages.language-server.eslint = {
        args = ["--stdio"];
        command = "vscode-eslint-language-server";
        config.nodePath = "";
        config.quiet = false;
        config.rulesCustomizations = [];
        config.run = "onType";
        config.validate = "on";
        config.codeAction.disableRuleComment.enable = true;
        config.codeAction.disableRuleComment.location = "separateLine";
        config.codeAction.showDocumentation.enable = true;
        config.problems.shortenToSingleLine = false;
      };

      languages.language-server.jdtls.config.java = {
        autobuild.enabled = true;
        completion.maxResults = 1000;
        format.settings.url = "https://raw.githubusercontent.com/google/styleguide/gh-pages/eclipse-java-google-style.xml";
      };

      languages.language-server.rust-analyzer.config.files.watcher = "client";

      languages.language = [
        {
          name = "typescript";
          language-servers = [ "typescript-language-server" "vscode-eslint-language-server" ];
          indent.tab-width = 4;
          indent.unit = "    ";
        }
        {
          name = "tsx";
          language-servers = [ "typescript-language-server" "vscode-eslint-language-server" ];
          indent.tab-width = 4;
          indent.unit = "    ";
        }
        {
          name = "java";
          indent.tab-width = 4;
          indent.unit = "    ";
        }
      ];
    };
  }

Nh

nh is an alternative frontend to home-manager and a few other nix tools that I'm trying out. It shows what's changing when you update your config, which is nice.

  {
    programs.nh = {
      enable = true;
    };
  }

Starship

starship gives me a nice shell prompt, mostly showing the versions of relevant software I have installed. It's shell-agnostic, so it works with both bash and zsh.

  {
    programs.starship = {
      enable = true;
      settings = {
        add_newline = false;
        container.disabled = true;
        git_branch.symbol = " ";
        git_status.ahead = "⇡\${count}";
        git_status.behind = "⇣\${count}";
        git_status.diverged = "⇕⇡\${ahead_count}⇣\${behind_count}";
        git_status.format = "([\\[\$conflicted\$staged\$ahead_behind\\]](\$style) )";
        java.symbol = " ";
        line_break.disabled = true;
        nix_shell.symbol = " ";
        nodejs.symbol = " ";
        package.disabled = true;
        palette = "catppuccin_frappe";
        python.symbol = " ";
        package.symbol = " ";
        rust.symbol = " ";
        docker_context.disabled = true;
        shell.disabled = false;
      };
    };
  }

Tmux

I'm using wezterm instead of tmux for now, so this is disabled, but I'm keeping the config here in case I need it later.

  {pkgs, ...}:
  {
    programs.tmux = {
      baseIndex = 1;
      clock24 = true;
      customPaneNavigationAndResize = true;
      historyLimit = 50000;
      enable = true;
      escapeTime = 0;
      keyMode = "vi";
      mouse = true;
      shell = pkgs.zsh + "/bin/zsh";
      shortcut = "Space";
      tmuxinator.enable = true;
      terminal = "xterm-256color";
      extraConfig = ''
  bind-key -T copy-mode-vi 'v' send -X begin-selection
  bind-key -T copy-mode-vi 'y' send -X copy-selection-and-cancel

  bind-key -T launcher g popup -h 100% -w 100% -E lazygit
  bind-key g switch-client -Tlauncher
  set -g default-command ""
      '';
    };
  }

Wezterm

wezterm is a fast terminal emulator and multiplexer. It is configured using lua. We'll define its config in two blocks, so we can get lua syntax highlighting in org. First, the nix configuration:

  {pkgs, ...}: {
    programs.wezterm = {
      enable = true;
      extraConfig = ''
        local config = {}
        config.default_prog = { '${pkgs.zsh}/bin/zsh', '-l'}
        config.font_size = ${if pkgs.stdenv.isDarwin then "13.0" else "10.0"}
        '' + builtins.readFile ./wezterm.lua;
    };
  }

Then the real lua config:

  local config = {}
  config.default_prog = { '/Users/jfrikker/.nix-profile/bin/zsh', '-l' }
  config.font = wezterm.font 'Iosevka Term SS14'
  config.font_size = 13.0
  -- config.font = wezterm.font("JetBrains Mono")
  config.inactive_pane_hsb = {
    saturation = 0.5,
    brightness = 0.5,
  }
  config.pane_focus_follows_mouse = true
  config.switch_to_last_active_tab_when_closing_tab = true
  config.tab_bar_at_bottom = true
  config.use_fancy_tab_bar = false
  config.window_decorations = "RESIZE"

I use a workspace switcher plugin, bouned to cmd-s, that lets me quickly switch between per-project workspaces using a single OS window.

  local workspace_switcher = wezterm.plugin.require("https://github.com/MLFlexer/smart_workspace_switcher.wezterm")
  workspace_switcher.zoxide_path='~/.nix-profile/bin/zoxide'

Set up a default window layout when switching to a workspace that hasn't been opened in this session yet. This will create three tabs, caled "edit", "run", and "term", and open helix in the first one. I use "edit" for running the editor (obviously), "run" for building / running the application, and "term" for miscellaneous other tasks. I sometimes split the "run" window into multiple panes if the project requires multiple things to run simultaneously.

  wezterm.on('smart_workspace_switcher.workspace_switcher.created', function(window, path, workspace)
    local editor = window:active_tab()
    editor:set_title("edit")
    editor:panes()[1]:send_text("hx\n")
    local run = window:spawn_tab {}
    run:set_title "run"
    local term = window:spawn_tab {}
    term:set_title "term"
    editor:activate()
    end)

Put the current workspace name in the lower-right corner of the window. Taken from [https://alexplescan.com/posts/2024/08/10/wezterm/].

  local function segments_for_right_status(window)
     return {
        window:active_workspace(),
     }
  end

  wezterm.on('update-status',
             function(window, _)
                local SOLID_LEFT_ARROW = utf8.char(0xe0b2)
                local segments = segments_for_right_status(window)
                
                local color_scheme = window:effective_config().resolved_palette
                -- Note the use of wezterm.color.parse here, this returns
                -- a Color object, which comes with functionality for lightening
                -- or darkening the colour (amongst other things).
                local bg = wezterm.color.parse(color_scheme.background)
                local fg = color_scheme.foreground

                -- Each powerline segment is going to be coloured progressively
                -- darker/lighter depending on whether we're on a dark/light colour
                -- scheme. Let's establish the "from" and "to" bounds of our gradient.
                local gradient_to, gradient_from = bg
                gradient_from = gradient_to:lighten(0.2)
                
                -- Yes, WezTerm supports creating gradients, because why not?! Although
                -- they'd usually be used for setting high fidelity gradients on your terminal's
                -- background, we'll use them here to give us a sample of the powerline segment
                -- colours we need.
                local gradient = wezterm.color.gradient(
                   {
                      orientation = 'Horizontal',
                      colors = { gradient_from, gradient_to },
                   },
                   #segments -- only gives us as many colours as we have segments.
                )

                -- We'll build up the elements to send to wezterm.format in this table.
                local elements = {}

                for i, seg in ipairs(segments) do
                   local is_first = i == 1

                   if is_first then
                      table.insert(elements, { Background = { Color = 'none' } })
                   end
                   table.insert(elements, { Foreground = { Color = gradient[i] } })
                   table.insert(elements, { Text = SOLID_LEFT_ARROW })

                   table.insert(elements, { Foreground = { Color = fg } })
                   table.insert(elements, { Background = { Color = gradient[i] } })
                   table.insert(elements, { Text = ' ' .. seg .. ' ' })
                end

                window:set_right_status(wezterm.format(elements))
  end)

Now we'll set up some keybindings:

Key	Action
s-s	Switch Workspace
s–	Vertical Split
s-\	Horizontal split
s-hjkl	Switch to the pane in that direction
s-g	Launch lazygit in a new tab. The tab closes when lazygit exits.
s-z	Toggle full-screen zoom for the active pane.
s-t	Launch a terminal in a new tab.
s-d	Close the current tab (with confirmation).
s-123456789	Switch to the tab with the corresponding number.

  config.leader = { key = ' ', mods = 'CTRL', timeout_milliseconds = 10000 }
  config.keys = {
    {
  key = "s",
  mods = "CMD",
  action = workspace_switcher.switch_workspace(),
    },
    {
  key = "-",
  mods = "CMD",
  action = wezterm.action.SplitVertical {},
    },
    {
  key = "\\",
  mods = "CMD",
  action = wezterm.action.SplitHorizontal {},
    },
    {
  key = "h",
  mods = "CMD",
  action = wezterm.action.ActivatePaneDirection "Left",
    },
    {
  key = "j",
  mods = "CMD",
  action = wezterm.action.ActivatePaneDirection "Down",
    },
    {
  key = "k",
  mods = "CMD",
  action = wezterm.action.ActivatePaneDirection "Up",
    },
    {
  key = "l",
  mods = "CMD",
  action = wezterm.action.ActivatePaneDirection "Right",
    },
    {
  key = "g",
  mods = "CMD",
  action = wezterm.action.SpawnCommandInNewTab {
    args = { wezterm.home_dir .. "/.nix-profile/bin/zsh", "-l", "-i", "-c", "lazygit" }
  }
    },
    {
  key = "t",
  mods = "CMD",
  action = wezterm.action.SpawnCommandInNewTab {}
    },
    {
  key = 'z',
  mods = 'CMD',
  action = wezterm.action.TogglePaneZoomState,
    },
    {
  key = 'd',
  mods = 'CMD',
  action = wezterm.action.CloseCurrentTab { confirm = true },
    },
  }

  for i = 1, 9 do
    -- CTRL+ALT + number to activate that tab
    table.insert(config.keys, {
  key = tostring(i),
  mods = 'LEADER',
  action = wezterm.action.ActivateTab(i - 1),
    })
  end

        "ctrl+2" = "goto_tab 2";
        "ctrl+3" = "goto_tab 3";

Ghostty

Disabled until I can get it working on both linux and mac (if I want to).

  {pkgs, ...}: {
    programs.ghostty = {
      enable = true;
      package = pkgs.ghostty-bin;
      settings = {
        adjust-cell-height = "15%";
        font-family = "Iosevka Term SS14";
        font-size = 13;
      };
    };
  }

Zsh

This is my default shell for now. Unfortunately, nix requires a posix-compliant shell, so bash or zsh it is.

  {
    programs.zsh = {
      enable = true;
      oh-my-zsh.enable = true;
      syntaxHighlighting.enable = true;
      autosuggestion.enable = true;
      historySubstringSearch.enable = true;
      history.share = false;
      cdpath = ["~/source"];
    };
  }

Actually, nix really requires bash. This is a plugin that allows using zsh from nix-shell.

  {pkgs, ...}:
  {
    programs.zsh.plugins = [
      {
        name = "zsh-nix-shell";
        file = "nix-shell.plugin.zsh";
        src = pkgs.fetchFromGitHub {
          owner = "chisui";
          repo = "zsh-nix-shell";
          rev = "v0.7.0";
          sha256 = "149zh2rm59blr2q458a5irkfh82y3dwdich60s9670kl3cl5h2m1";
        };
      }
    ];
  }

Claude Code

  {claude-code, ...}: {
    programs.claude-code = {
      enable = true;
      package = claude-code;
    };
  }

Emacs

Emacs is a huge portion of this configuration, so although it's a home-manager "program", I'm breaking it out into its own top-level section. Many of the sections here have two code blocks: a nix code block listing the emacs packages to include, and an elisp code block to configure them in emacs.

We'll put the actual emacs configs into separate files, rather than into nix string literals. This helps with a few places where nix's string interpolation was causing problems.

Keybindings

These keybindings are scattered throughout this file, I'm collecting them all here to make it easier to track them.

Key	Normal Key	Action	Mode
s-b		Switch project buffer
s-B		Switch buffer
s-f	C-x p f	Open file in current project
s-F	C-x p p	Switch project
S-s	C-x t RET	Switch tab
C-c A		Org agenda
C-c a		Eglot code actions	prog
C-c c		Claude Code
C-c C		Org capture
C-c D		Show flymake diagnostics	prog
C-c h		Consult shell history
C-c i		Eglot find implementation	prog
C-c l		Org store link
C-c n		Org Roam prefix
C-c r		Eglot rename	prog
C-c u		Cycle string inflection	various
C-c M-g		Magit file dispatch

Global Settings

These are just some general settings that apply everywhere. First, a few packages:

  {
    programs.emacs = {
      enable = true;
      extraPackages = epkgs: with epkgs; [
        ace-window
        doom-modeline
        free-keys
        ligature
        mixed-pitch
        popper
      ];
      extraConfig = builtins.readFile ./emacs-global.el;
    };
  }

Turn off some default settings that I don't find useful.

  (setopt save-interprogram-paste-before-kill t)
  (setopt enable-recursive-minibuffers t)
  (setopt line-spacing 0.15)

  (setopt mouse-wheel-tilt-scroll t)
  (setq-default truncate-lines t)

  (setopt tab-bar-show nil)
  (tab-bar-mode)

Don't show the welcome screen, and keep the scratch buffer empty by default. These are not useful after you've started emacs more than a few times.

  (setopt inhibit-startup-screen t)
  (setopt initial-scratch-message nil)

Turn off all the ugly graphical crap.

  (menu-bar-mode -1)
  (scroll-bar-mode -1)
  (tool-bar-mode -1)

I don't find emacs's backup files useful, and they seem to litter my directories. I could maybe see a use if I wasn't using git. But, git is so easy to use, that I pretty much use it everywhere. I don't need a poor man's local history.

Also, why do I have to set so many variables just to get emacs to stop putting extra files everywhere?

  (setopt make-backup-files nil)
  (setopt create-lockfiles nil)
  (setopt auto-save-default nil)

Turn on view-mode automatically when the buffer is read-only. This just helps out with navigation a bit. I almost want to open files read-only by default, just so I can use view-mode (maybe with some other keybindings) all the time. But, I think one more invisible flag to manage is a bit much.

  (setopt view-read-only t)

I don't really do anything with sentences. But, I also never put two spaces after a period. So, at least this setting is correct.

  (setopt sentence-end-double-space nil)

I kill whole lines way more than partial lines. If the cursor is at the front of a line, this will just kill the whole line instead of requiring two C-k C-k presses to make it happen. I'm not sure when I'd ever want it to kill the line without the trailing newline, but I guess the one time ever that I do, I'll have to press two more keys :(

  (setopt kill-whole-line t)

Show column numbers in the modeline. Now that I think about it, I'm not sure why I want this. I guess I could try turning it off someday?

  (column-number-mode t)

Make sure which-key mode is always on. The on-the-fly keymap help it gives is indespensable.

  (which-key-mode)

Automatically refresh dired buffers when switching to them, instead of requiring an explicit refresh.

  (setopt dired-auto-revert-buffer t)

Similarly, highlighting the line the cursor is on is really useful for figuring out where you are, especially on monitors with a lot of vertical space.

  (global-hl-line-mode)

From the docs: "If ‘complete’, TAB first tries to indent the current line, and if the line was already indented, then try to complete the thing at point." Recommended by the corfu readme.

  (setopt tab-always-indent 'complete)

Set the cursor to be a bar. I'm not sure what the benefit would be of a block cursor, since the current character isn't really "selected" like it would be in Helix. I switch this to a box when in god mode / read-only buffers, like vim would.

  (setq-default cursor-type 'bar)

Repeat-mode takes care of eliminating some annoying duplicate keypresses. I mostly use repeat-mode for two-character commands that need to be repeated; devil also has some single-key-with-modifier repeats set up that only apply in that mode.

  (repeat-mode)

Save the minibuffer history to disk, so recently-used options show up at the top of the picker across restarts.

  (savehist-mode)

Let's unbind some builtin keys that I don't use. I'm not sure if I'll replace them with anything or not, but at a minimum it'll avoid accidental keypresses and clean up which-key output.

  (unbind-key "C-x RET")
  (unbind-key "C-x #")
  (unbind-key "C-x 5")
  (unbind-key "C-x 6")
  (unbind-key "C-x \\")
  (unbind-key "C-x `")
  (unbind-key "C-x m")
  (unbind-key "C-x l")
  (unbind-key "C-x i")
  (unbind-key "C-x u")
  (unbind-key "C-x @")
  (unbind-key "C-x C-b")
  (unbind-key "C-x C-d")
  (unbind-key "C-x C-l")
  (unbind-key "C-x C-p")
  (unbind-key "C-x C-u")
  (unbind-key "C-x C-z")

The doom modeline looks nice. I'm turning off IRC notifications, because it was slow to update (and it would update after every command, slowing down everything). I don't need the workspace name when I have the tab bar at the top of the window. The other settings just clear up some space, and make things look at little nicer.

  (setopt doom-modeline-irc nil)
  (setopt doom-modeline-workspace-name nil)
  (setopt doom-modeline-buffer-encoding nil)
  (setopt doom-modeline-vcs-max-length 30)
  (doom-modeline-mode)

Ligature mode combines character sequences like <= into a single on-screen glyph. It looks kind of cool, so I'm turning it on in prog mode. The enabled ligatures are font-specific, taken from the ligature wiki.

  (ligature-set-ligatures 'prog-mode

Use variable-width fonts in text buffers. mixed-pitch-mode keeps most code blocks as monospace.

  (add-hook 'text-mode-hook 'mixed-pitch-mode)

  (defun no-mixed-pitch ()
    (mixed-pitch-mode -1))

  (add-hook 'nxml-mode 'no-mixed-pitch)

A basic ace-window setup. Allows switching between windows quickly (although avy can do the same…).

  (bind-keys ("M-o" . ace-window)
             ("s-o" . ace-window)
             ("C-c o" . ace-window))
  (setopt aw-keys '(?a ?s ?d ?f ?g ?h ?j ?k ?l))
  (setopt aw-dispatch-always t)

Set up a few project- / workspace-related key bindings.

  (bind-keys ("s-f" . project-find-file)
             ("s-F" . project-switch-project)
             ;; ("s-s" . persp-switch)
             )

  (with-eval-after-load 'tab-bar
    (bind-keys :map tab-bar-mode-map
               ("s-s" . tab-bar-switch-to-tab)))

tab-bar-switch-to-tab

Don't run a server. I'm not using this, I can always turn it back on if I need to.

  (server-mode -1)

All the beeping is annoying. This flashes a huge icon over the screen, which is still annoying, but less so?

  (setopt visible-bell t)

I'm trying this out. This disables visual selections. It's bold, which is why I like it :)

  (transient-mark-mode -1)

I use tabs to manage multiple "workspaces". I don't tie a project to a tab or anything; often fixing a single bug might involve pulling in files from multiple projects. Rather, I open a file per bug / fix / issue, and leave it open until I'm done with that issue.

tab-bar-history-mode allows quickly rolling back window changes; it can be used to undo a context change when drilling into a help page or something. I've set up repeat mode to make it easier to move backward / forward through history.

  (bind-keys :repeat-map tab-bar-repeat-map
             ("<left>" . tab-bar-history-back)
             ("<right>" . tab-bar-history-forward))

  (tab-bar-history-mode)

Make compilation mode buffers auto-scroll to the first error:

  (setopt compilation-scroll-output 'first-error)

Window Placement

This section contains rules about where display-buffer should place windows. I guess I'm currently going for an IDE-style layout, with one main editor window, and auxiliary bottom and right side windows. I place windows in the bottom or on the right mostly depending on how wide I expect their content to be.

  (defun jf/window-children (window)
    (let ((result nil)
          (child (window-child window)))
      (while child
        (push child result)

      (reverse result)))

          (seq-find (lambda (w) (not (window-parameter w 'window-side))) children)
        root)))

  (defun jf/window-leaves (window)
    "Return the live leaf windows in WINDOW's subtree."
    (if (window-live-p window)
        (list window)
      (mapcan #'jf/window-leaves (jf/window-children window))))

  (defun jf/topright-window (windows)
    "Return whichever of WINDOWS sits furthest up, then furthest right."
    (car (sort (copy-sequence windows)
               (lambda (a b)
                 (let ((top-a (nth 1 (window-edges a)))
                       (top-b (nth 1 (window-edges b))))
                   (if (= top-a top-b)
                       (> (nth 0 (window-edges a)) (nth 0 (window-edges b)))
                     (< top-a top-b)))))))

Editing

This configuration affects general text editing, across all modes. First, some packages:

  {
    programs.emacs = {
      enable = true;
      extraPackages = epkgs: with epkgs; [
        apheleia
        avy
        edit-indirect
        embark
        god-mode
        # evil
        # evil-collection
        # evil-org
        string-inflection
      ];
      extraConfig = builtins.readFile ./emacs-editing.el;
    };
  }

I find Emacs to be almost unusable on a normal keyboard unless there's some way to avoid all the modifier keys. I tried Evil mode first. But although I love Vim, it just seemed to be hiding too much of the Emacs native functionality. The keybindings were also much harder to configure. I tried God mode, which has the benefit of re-using the normal Emacs keybindings and commands. It was annoying, though, because some read-only buffers (like magit buffers) have their own "normal-mode" commands that don't use modifiers. It felt jarring to switch to "insert mode" to use those keys. It's also hard to repeat sequences of M-f, M-b, etc. I could have made a ton of repeat maps, but I'm worried that having too many repeat maps will also be annoying (I'll have to explicitly cancel them more frequently). In the end, I opted for Devil mode. It avoids modifier keys, and has its own devil-mode-only repeat maps that don't interfere when using normal modifier key sequences.
