* Overall Structure

This is the basic structure of the home.nix file. Individual sections are defined later.

#+BEGIN_SRC nix :noweb no-export :tangle home.nix
  { config, pkgs, ... }:

  {
    home.stateVersion = "22.05";

    <<personal>>

    home.packages = with pkgs; [
      <<packages>>
    ];

    <<path>>

    programs = {
      <<programs>>
    };

    xdg = {
      enable = true;
      <<extra_xdg>>
    };
  }
#+END_SRC

* Personal Info

Home manager requires this stuff. Just my name and where my home directory is. At some point, I need to make this more dynamic (perhaps using chezmoi), but for now it's hard-coded.

#+NAME: personal
#+BEGIN_SRC nix
  home.username = "jfrikker";
  home.homeDirectory = "/Users/jfrikker";

* Packages

~SBCL~ is the current leading open-source common lisp compiler. It requires any libraries you want to be availble to be installed using withPackages. I really should install this per-project using direnv, rather than globally. I think it may work today, but I think I want to start using ~SBCL~ for scripting / exploratory development. So for now, it stays global.

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

Chezmoi is what I use to manage this file; it can pull it from GitHub, and handle a few configuration variations. I may be able to replace it with org mode?

* Program Configurations
:PROPERTIES:
:header-args: :noweb-ref programs :noweb no-export
:END:

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.

#+BEGIN_SRC nix
  bash.enable = true;
  gh.enable = true;
  home-manager.enable = true;
  jq.enable = true;
  lazygit.enable = true;
  zoxide.enable = true;
#+END_SRC

** 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.

#+BEGIN_SRC nix
    bat.enable = true;
    bat.config.style = "numbers";
#+END_SRC

** 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.

#+BEGIN_SRC nix
  direnv.enable = true;
  direnv.nix-direnv.enable = true;
#+END_SRC

** Eza

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

#+BEGIN_SRC nix
  eza.enable = true;
  eza.enableBashIntegration = true;
  eza.enableZshIntegration = true;
  eza.icons = "auto";
#+END_SRC

** 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.

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

** Git

We all know what ~git~ does.

#+BEGIN_SRC nix
  git.enable = true;
  git.settings.user.name = "Joe Frikker";
  git.settings.user.email = "joe.frikker@shibumi.com";
  delta.enable = true;
  delta.enableGitIntegration = true;
#+END_SRC

** Helix

The best text editor ever? Heresy!

#+BEGIN_SRC nix
  helix.enable = true;
  helix.defaultEditor = true;

  helix.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;

    text-width = 100;
    lsp.goto-reference-include-declaration = false;
    cursor-shape.insert = "bar";
    smart-tab.supersede-menu = true;
    whitespace.render.newline = "all";
  };

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


  helix.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;
  };

  helix.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";
  };

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

  helix.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;

      }
      {
          name = "java";
          indent.tab-width = 4;
          indent.unit = "    ";
      }
  ];
#+END_SRC

** 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.

#+BEGIN_SRC nix :noweb no-export
  starship.enable = true;
  starship.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;
  } //
    <<starship_colors>>
  ;
#+END_SRC

** 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.

#+BEGIN_SRC nix
  tmux.baseIndex = 1;
  tmux.clock24 = true;
  tmux.customPaneNavigationAndResize = true;
  tmux.historyLimit = 50000;
  tmux.enable = true;
  tmux.escapeTime = 0;
  tmux.keyMode = "vi";
  tmux.mouse = true;
  tmux.shell = pkgs.zsh + "/bin/zsh";
  tmux.shortcut = "Space";
  tmux.tmuxinator.enable = true;
  tmux.terminal = "xterm-256color";
  tmux.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 ""
    '';
#+END_SRC
** 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:

#+BEGIN_SRC nix :noweb no-export
  wezterm.enable = true;
  wezterm.extraConfig = ''
    local config = {}
    <<wezterm_colors>>
    <<wezterm>>
  '';
#+END_SRC

Then the real lua config:

#+BEGIN_SRC lua :noweb-ref wezterm
  config.default_prog = { '/Users/jfrikker/.nix-profile/bin/zsh', '-l' }
  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"
#+END_SRC

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

#+BEGIN_SRC lua :noweb-ref wezterm
  local workspace_switcher = wezterm.plugin.require("https://github.com/MLFlexer/smart_workspace_switcher.wezterm")
  workspace_switcher.zoxide_path='~/.nix-profile/bin/zoxide'
#+END_SRC

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.

#+BEGIN_SRC lua :noweb-ref wezterm
  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)

#+END_SRC

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

#+BEGIN_SRC lua :noweb-ref 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)
#+END_SRC

Now we'll set up some keybindings:

| Key         | Action                                                              |

#+BEGIN_SRC lua :noweb-ref wezterm

  end

  return config
#+END_SRC

** Zsh

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

#+BEGIN_SRC nix
  zsh.enable = true;
  zsh.oh-my-zsh.enable = true;
  zsh.syntaxHighlighting.enable = true;
  zsh.autosuggestion.enable = true;
  zsh.historySubstringSearch.enable = true;
  zsh.history.share = false;
  zsh.cdpath = ["~/source"];
#+END_SRC

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

#+BEGIN_SRC nix
  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";
      };
    }
  ];
#+END_SRC

* 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.

#+BEGIN_SRC nix :noweb no-export :noweb-ref programs
  emacs.enable = true;
  emacs.extraPackages = epkgs: with epkgs; [
    <<emacs_packages>>
  ];
  emacs.extraConfig = ''
    <<emacs_early>>
    <<emacs_config>>
  '';
#+END_SRC

** Global Settings

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

#+BEGIN_SRC nix :noweb-ref emacs_packages
  doom-modeline
  ligature
  mixed-pitch
  ace-window
#+END_SRC

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

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (setq inhibit-startup-screen t)
  (setq initial-scratch-message nil)
  (menu-bar-mode -1)
  (scroll-bar-mode -1)
  (tool-bar-mode -1)
  (setq make-backup-files nil)
  (setq split-window-threshold 200)
  (setq split-height-threshold 200)
  (setq view-read-only t)
#+END_SRC

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

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (which-key-mode)
#+END_SRC

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

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (setq dired-auto-revert-buffer t)
#+END_SRC

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.

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (global-hl-line-mode)
#+END_SRC

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 [[https://github.com/minad/corfu][the ~corfu~ readme]].

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (setq tab-always-indent 'complete)
#+END_SRC

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. When I had God mode set up, I switched to a block cursor during normal mode, just because I was so used to it from Helix and Vim. Now, I don't think there's really a need to ever switch.

#+BEGIN_SRC elisp :noweb-ref emacs_config
  (setq-default cursor-type 'bar)
#+END_SRC

Emacs is supposed to be all about automation (maybe?). There's basically never a case where I don't want changes I've made to be immediately saved to disk. So let's have Emacs do that. There's still a fairly long (~5 sec) delay before changes are saved, which is kind of annoying. Maybe I'll look into that at some point?

#+BEGIN_SRC elisp :noweb-ref emacs_config

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.

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.

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 [[https://github.com/mickeynp/ligature.el/wiki#jetbrains-mono][the ligature wiki]].

** Editing

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

#+END_SRC

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.
