Consent morality is the idea that there are no higher values or virtues than allowing consenting adults to do whatever they please. As long as they're not hurting anyone, it's all good, and whoever might have a problem with that is by definition a bigot.  This was the overriding morality I picked up as a child of the 90s. From TV, movies, music, and popular culture. Fly your freak! Whatever feels right is right! It doesn't seem like much has changed since then. What a moral dead end. I first heard the term consent morality as part of Louise Perry's critique of the sexual revolution. That in the context of hook-up culture, situationships, and falling birthrates, we have to wrestle with the fact that the sexual revolution — and it's insistence that, say, a sky-high body count mustn't be taboo — has led society to screwy dating market in the internet age that few people are actually happy with. But the application of consent morality that I actually find even more troubling is towards parenthood. As is widely acknowledged now, we're in a bit of a birthrate crisis all over the world. And I think consent morality can help explain part of it. I was reminded of this when I posted a cute video of a young girl so over-the-moon excited for her dad getting off work to argue that you'd be crazy to trade that for some nebulous concept of "personal freedom". Predictably, consent morality immediately appeared in the comments: Some people just don't want children and that's TOTALLY OKAY and you're actually bad for suggesting they should! No. It's the role of a well-functioning culture to guide people towards The Good Life. Not force, but guide. Nobody wants to be convinced by the morality police at the pointy end of a bayonet, but giving up on the whole idea of objective higher values and virtues is a nihilistic and cowardly alternative. Humans are deeply mimetic creatures. It's imperative that we celebrate what's good, true, and beautiful, such that these ideals become collective markers for morality. Such that they guide behavior. I don't think we've done a good job at doing that with parenthood in the last thirty-plus years. In fact, I'd argue we've done just about everything to undermine the cultural appeal of the simple yet divine satisfaction of child rearing (and by extension maligned the square family unit with mom, dad, and a few kids). Partly out of a coordinated campaign against the family unit as some sort of trad (possibly fascist!) identity marker in a long-waged culture war, but perhaps just as much out of the banal denigration of how boring and limiting it must be to carry such simple burdens as being a father or a mother in modern society. It's no wonder that if you incessantly focus on how expensive it is, how little sleep you get, how terrifying the responsibility is, and how much stress is involved with parenthood that it doesn't seem all that appealing! This is where Jordan Peterson does his best work. In advocating for the deeper meaning of embracing burden and responsibility. In diagnosing that much of our modern malaise does not come from carrying too much, but from carrying too little. That a myopic focus on personal freedom — the nights out, the "me time", the money saved — is a spiritual mirage: You think you want the paradise of nothing ever being asked of you, but it turns out to be the hell of nobody ever needing you. Whatever the cause, I think part of the cure is for our culture to reembrace the virtue and the value of parenthood without reservation. To stop centering the margins and their pathologies. To start centering the overwhelming middle where most people make for good parents, and will come to see that role as the most meaningful part they've played in their time on this planet. But this requires giving up on consent morality as the only way to find our path to The Good Life. It involves taking a moral stance that some ways of living are better than other ways of living for the broad many. That parenthood is good, that we need more children both for the literal survival of civilization, but also for the collective motivation to guard against the bad, the false, and the ugly. There's more to life than what you feel like doing in the moment. The worst thing in the world is not to have others ask more of you. Giving up on the total freedom of the unmoored life is a small price to pay for finding the deeper meaning in a tethered relationship with continuing a bloodline that's been drawn for hundreds of thousands of years before it came to you. You're never going to be "ready" before you take the leap. If you keep waiting, you'll wait until the window has closed, and all you see is regret. Summon a bit of bravery, don't overthink it, and do your part for the future of the world. It's 2.1 or bust, baby!

CodeMirror 6 has @codemirror/search package which provides UI for searching within a document, triggered via Ctrl + F. In my note-taking application Edna I wanted something slightly different. This article describes how I implemented it. The UI went from: to: CodeMirror is very customizable which is great, but makes it hard to understand how to put the pieces together to achieve desired results. Almost all of the work is done in @codemirror/search, I just plugged my own UI into framework designed by the author of CodeMirror. How to get standard search UI in CodeMirror When you create CodeMirror you configure it with: import { highlightSelectionMatches, searchKeymap, } from "@codemirror/search"; EditorState.create({ // ... other stuff extensions: [ // ... other stuff highlightSelectionMatches(), keymap.of([ // ... other stuff ...searchKeymap, ]), ] }) searchKeymap is what registers key bindings like Ctrl + F to invoke search UI, F3 to find next match etc. highlightSelectionMatches is an extension that visually highlights search matches. Customizing the UI CodeMirror 6 has a notion of UI panels. Built-in search UI is a panel. Custom search UI panel Thankfully panel is as generic as it can be: it’s just a div hosting the UI. The author predicted the need for providing custom search UI so it’s as easy as adding search extension configured with custom search panel creation function: import { search, } from "@codemirror/search"; function createFindPanel() { ... } EditorState.create({ // ... other stuff extensions: [ // ... other stuff search({ createPanel: createFnddPanel, }), ] }) All the options to search() are documented here. Create the panel Function that creates the panel returns a DOM element e.g. a <div>. You can create that element using vanilla JavaScript or using a framework like Svelte, React, Vue. For Svelte the trick is to manually instantiate the component. I use Svelte 5 so I’ve created Find.svelte component which floats over the editor area thanks to position: fixed. Here’s how to manually mount it: import Find from "../components/Find.svelte"; import { mount } from "svelte"; function createFnddPanel(view) { const dom = document.createElement("div"); const args = { target: dom, props: { view, }, }; mount(Find, args); return { dom, top: true, }; } If you provide createPanel function, @codemirror/search will call it to create search UI instead of its own. It’s a great design because it reuses most of the code in @codemirror/search. The UI can be triggered programmatically, by calling openSearchPanel(EditorView) (and closed with closeSearchPanel(EditorView). Or By Mod + F key binding defined in searchKeymap. You can change the binding by not including searchKeymap and instead provide your own array of bindings to functions from @codemirror/search. By default CodeMirror shrinks the editor area to host the UI. It can host it either at the top or the bottom of the editor, which is what top return value indicates. In my case value of top doesn’t matter because my UI floats on top of editor with position: fixed and z-index: 20 so we don’t shrink the editor area. The DOM element you create is hosted within this structure: <div class="cm-panels cm-panels-top" style="top: 0px;"> <div class="cm-panel"> <!-- YOUR DOM ELEMENT --> </div> </div> My CSS provided with EditorView.theme() was: const themeBase = EditorView.theme({ ".cm-panels .cm-panel": { boxShadow: "0 0 10px rgba(0,0,0,0.15)", padding: "8px 12px", }, }); The padding made the wrapper element visible even though I didn’t want it. To fix it I simply changed it to: EditorView.theme({ ".cm-panels .cm-panel": { }, }); Doing the searches When user changes the text in input field, we need tell CodeMirror 6 to do the search. You talk to CodeMirror using those commands. To start a new search you do: let query = new SearchQuery({ search: searchTerm, replace: replaceTerm, // if you're going to run replacement commands caseSensitive: false, literal: true, }); view.dispatch({ effects: setSearchQuery.of(query), }); CodeMirror 6 supports regex search, matching case, matching only whole world option. See SearchQuery docs. To instruct CodeMirror to navigate to next, previous match etc. you call: findNext : advance to next match in the editor findPrevious : go to previous match replaceNext : replace next match replaceAll : replace all matches All those function take EditorView as an argument and act based on the last SearchQuery. All commands are documented here. Doing it in Svelte 5 Here’s the core of the component: <div class="flex"> <input bind:this={searchInput} type="text" spellcheck="false" placeholder="Find" bind:value={searchTerm} class="w-[32ch]" use:focus onkeydown={onKeyDown} /> <button onclick={next} title="find next (Enter}">next</button> <button onclick={prev} title="find previous (Shift + Enter)">prev </button> <button onclick={all} title="find all">all </button> </div> <div class="flex"> <input type="text" spellcheck="false" placeholder="Replace" bind:value={replaceTerm} class="w-[32ch]" /> <button onclick={replace}>replace</button> <button onclick={_replaceAll} class="grow">all</button> </div> We do “search as you type” by observing changes to searchTerm input field: $effect(() => { let query = new SearchQuery({ search: searchTerm, replace: replaceTerm, caseSensitive: false, literal: true, }); view.dispatch({ effects: setSearchQuery.of(query), }); }); On button press we invoke desired functionality, like: function next() { findNext(view); } Pre-populating input from selection When we show search UI it’s nice to pre-populate search term with current selection. It’s as easy as: import { getSearchQuery, } from "@codemirror/search"; let query = getSearchQuery(view.state); searchTerm = query.search; This must be done on component initialization, not in onMount(). As addition trick, we select the content of input field: onMount(() => { tick().then(() => { searchInput.select(); }); }); Closing search panel on Esc I wanted to hide search UI when Escape key is pressed. Thankfully we get searchPanelOpen(EditorView) function that tells us if search panel is open and closeSearchPanel(EditorView) to close. So it’s as easy as: function onKeyDown(ev) { if (ev.key === "Escape") { let view = getEditorView(); if (view && searchPanelOpen(view.state)) { closeSearchPanel(view); return; } } } Customizing the look of search matches CodeMirror 6 is built on web technologies so the way it allows customizing the look of things is by applying known CSS styles. You provide your own CSS to change the look of things. Here’s the CSS for search matches: <!-- this is how all matches are highlighted --> <span class="cm-searchMatch"><span class="cm-selectionMatch">another</span></span> <!-- this is how currently selected match is higlighted. It changes with findNext() / findPrevious() / selectMatches() --> <span class="cm-searchMatch cm-searchMatch-selected">another</span> How to figure things out When I started working on this I did not know any of the above. Here’s my strategy for figuring this out. Look at the source code We live in open source world. The code to @codemirror/search is available so the first step was to look at it to see exported APIs etc. Look at the docs Ok, not really. I knew so little that even though CodeMirror has extensive documentation, I just couldn’t figure out how to put the pieces together. Ask omniscient AI I saw that there is setSearchQuery API but I didn’t know how to use it. I asked Grok: how to use setSearchQuery from @codemirror/search package in codemirror 6 It gave me a good response. Look at the code again So I tried sending new SearchQuery to the editor and it didn’t work i.e. I didn’t see the matches highlighted. Back to reading the code and I see that in searchHighlighter higlight() function, it doesn’t do anything if there’s no panel. But I want my own UI, not their panel, so hmm… See how others did it Surely there must be some open source project that did something similar. The trick is to find it. I used GitHub code search to look for distinct APIs, which is harder than it looks. If you search for findNext you’ll be flooded with results. So I searched for uses of @codemirror/search. I found a few projects that created custom search UIs and that gave me enough hints on how to use the APIs and how to put all the available pieces together. Resources Edna is a note taking application for developers and power users documentation of @codemirror/search my full implementation is in Find.svelte another implementation in Vue another implementation in vanilla JavaScript

I recently discussed how Espressif implements automatic reset, a feature that lets users easily update the code on an Espressif microcontroller. There are actually more subtleties than a quick look would suggest, and I spent a fair bit of time investigating them. This article and the next two present what I have learned.
