To that end, there are +a few things that I don't think I've seen other people do that I would like to +share here. + +## `home-manager` color scheme + +Some time ago, I came across the +[nix-colors](https://github.com/Misterio77/nix-colors) project and came to the +conclusion that it didn't fit my needs. As a result, I put/hacked a function +together that extracts the color schemes from +[`pkgs.kitty-themes`](https://search.nixos.org/packages?show=kitty-themes&query=kitty-themes). +I won't go into the integration details in my personal config as it's not +exactly something I would call ergonomic. However, this is the function I came +up with: + +{{< start-details summary="Expand to see a rather lengthy nix expression" >}} +```nix +{ lib, config, pkgs, ... }: +arg: +with lib; +let cfg = config.colorscheme; + + getKittyTheme = with builtins; (theme: + let matching = filter (x: x.name == theme) + (fromJSON + (readFile + "${pkgs.kitty-themes}/share/kitty-themes/themes.json")); + + in throwIf (length matching == 0) + "kitty-themes does not contain a theme named ${theme}" + "${pkgs.kitty-themes}/share/kitty-themes/${(head matching).file}"); + + unwrapKittyTheme = with pkgs; path: let + theme = runCommand "theme.toml" { nativebuildinputs = [ coreutils ]; } '' + cat '${path}' | sed -E '/^#|^$/d;s/\s+(.*)/ = "\1"/g' > $out + ''; + in (builtins.fromTOML (builtins.readFile theme)); + + defaultTheme = { + selection_foreground = ""; + selection_background = ""; + foreground = ""; + background = ""; + color0 = ""; + color1 = ""; + color2 = ""; + color3 = ""; + color4 = ""; + color5 = ""; + color6 = ""; + color7 = ""; + color8 = ""; + color9 = ""; + color10 = ""; + color11 = ""; + color12 = ""; + color13 = ""; + color14 = ""; + color15 = ""; + cursor = ""; + cursor_text_color = ""; + url_color = ""; + }; + +in defaultTheme // unwrapKittyTheme (getKittyTheme arg) +``` +{{< end-details >}} + +This function takes a name and matches that against the contents of +`pkgs.kitty-themes`. If it fails to find something, it throws an error; If does +find something, it returns that file, converts that to something approach TOML +syntax, which is then parsed using `builtins.fromTOML` and merged with a +minimum-viable-colorscheme, ensuring all colors are at the least declared as an +empty string; I ran into issues here when using this output in combination with +Qutebrowser when referring to colors that didn't exist in certain colorschemes. + +## Qutebrowser + +I manage my Qutebrowser config using the `home-manager` module (obviously). In +my Qutebrowser config, I have JavaScript disabled by default and use a list of +exception for trusted sites. When I first tried to set this up, I bumped into +the obvious problem that Nix doesn't allow you to bind multiple values to a +single name. Luckily, the Qutebrowser module has an `extraConfig` option which +takes a string. At first I had a bunch of lines for those exceptions: + +``` +config.set('content.javascript.enabled', True, 'https://hoogle.haskell.org/*') +config.set('content.javascript.enabled', True, 'https://search.nixos.org/*') +config.set('content.javascript.enabled', True, 'https://nix.dev/*') +config.set('content.javascript.enabled', True, 'https://voidcruiser.nl/searx/*') +``` + +However, I quickly got sick of the inherent inefficiency and illegibility of +this approach, so I wrote a few little functions: + +```nix +... +programs.qutebrowser.extraConfig = let + enableJS = url: "config.set('content.javascript.enabled', True, '${url}')"; + javaScriptExceptions = [ + "https://hoogle.haskell.org/*" + "https://search.nixos.org/*" + "https://nix.dev/*" + "https://voidcruiser.nl/searx/*" + ]; + in '' + ${with builtins; concatStringSep "\n" (map enableJS javaScriptExceptions)} + + # things I haven't managed to abstract properly yet + ''; +... +``` + +This takes the contents supplied in `javaScriptExceptions` and generates a +viable config line based on each item by mapping over it with the `enableJS` +function. Since the Qutebrowser config syntax can't read the nix list syntax, +the items of the resulting list and than concatenated using `\n` or a newline +character. + +# XMonad + +My XMonad configuration has a bunch of weird shit in it, some of which I'm proud +of, some of which still has bugs that I keep telling myself I will get to At +Some Point™. Here are some of the nicer bits. + +## Volume control using scroll wheel + +I have bound `Super + scroll {up,down}` bound to {increase,decrease} volume +respectively. + +```haskell +... + , ((modMask, button4), \_ -> safeSpawn "pulsemixer" ["--change-volume","+1"]) + , ((modMask, button5), \_ -> safeSpawn "pulsemixer" ["--change-volume","-1"]) + , ((modMask .|. shiftMask, button4), \_ -> safeSpawn "pulsemixer" ["--change-volume","+5"]) + , ((modMask .|. shiftMask, button5), \_ -> safeSpawn "pulsemixer" ["--change-volume","-5"]) +... + +``` + +The hard part here was coming to the realisation that using a lambda that +discards its argument was the best way to handle interactions while satisfying +the type signature. + +Other than that, these functions are quite straightforward. `button4` is 'scroll +up' while `button5` is 'scroll down'. I don't recall where I found this, but it +was somewhere in the documentation. As a result, when XMonad registers a +combination of `modMask` and either of the scroll directions, it uses +`pulsemixer` to increase or decrease the volume. + +## Kitty wrappers + +I use the [Kitty terminal](https://sw.kovidgoyal.net/kitty/). Kitty has a huge +feature list, of which I feel like I use about 20% at most. One of these +features is the ability to override config options using the `-o` parameter. +This allows you to set a different font(size) or colorscheme or what have you. + +I wanted to be able to start a `BQN` repl with the BQN386 font right from my +window manager. So I wrote a few functions that take various arguments and +supply them to Kitty without excessive syntax. + +The simplest one of these is `kittyWithOverrides`. It can only take a list of +`-o` parameters. + +```haskell +kittyWithOverrides :: [String] -> X () +kittyWithOverrides = spawn . ("kitty " ++) . (unwords . map ("-o " ++)) +``` + +Here is how I use this function to create a `BQN` repl window function: + +```haskell +largeTextBQN shell = [ "font_size=17" + , "font_family='BQN386 Unicode'" + , "shell='" ++ shell ++ "'" + ] + +bqn = kittyWithOverrides $ largeTextBQN "bqn" +``` + +_Note:_ I use a `largeTextBQN` function rather than a `where` binding, because I +use the same settings for a few other repls as well. + +This string will evaluate to the following at compile time: +``` +kitty -o font_size=17 -o font_family='BQN386 Unicode' -o shell='/nix/store/6xwwmv4ljbfckkyklh512zxy6l9s0wv4-cbqn-standalone-0.4.0/bin/bqn' +``` + +…which will then be fed to `spawn`, thereby executing it. If I were to spend +more time on it, I could figure out a way to do this properly using `safeSpawn` +or one of its variants, but as it stands, I'm too lazy to do so. + +For a more general interface I wrote a `kittyWithParams` function: + +```haskell +kittyWithParams :: [(String,String)] -> X () +kittyWithParams = spawn . ("kitty " ++) . unwords . map unwrapParams + where unwrapParams (flag,parameter) = case last flag of + '=' -> flag ++ parameter + _ -> flag ++ " " ++ parameter +``` + +Comparatively, it is rather messy. Still, the basic functionality is there and +I'm quite happy with how it works. diff --git a/src/content/services.md b/src/content/services.md index 9f4cc26..bc4eea6 100644 --- a/src/content/services.md +++ b/src/content/services.md @@ -16,11 +16,3 @@ I have got to say that the theming of SearXNG has improved quite a lot either ov At the very least I think the default theme looks quite nice these days. {{< noscript content="SearXNG does make use of JavaScript for certain functions, but it's purely to make using it a smoother experiece and it's perfectly functional without JavaScript." >}} - -# [Alpine repository](https://alpine.voidcruiser.nl)[(onion)](http://imerwns46jfdawado7xxb42i2kx7wjy6eyzugxehehxluh4hjqpebmyd.onion) - -I use [suckless' dwm](https://dwm.suckless.org) on every other machine I use. -Since I can't be bothered to always keep cloning the repo, I thought I'd make package based on it. -Why Alpine of all things?
