July is Disability Pride Month, an opportunity for us to consider how we’re serving our disabled community and work on breaking down barriers to access. Last year we had the pleasure of being introduced to Florian—a fully blind cybersecurity enthusiast—and thanks to his feedback we completely rewrote navigation in Onboarding to be more keyboard and screen reader friendly, as well as took another look at Installation and Initial Setup to vastly improve our entire first run experience for blind folks. Plus, we implemented the screen reader interface in the Alt + Tab window switcher. Thanks to this feedback, elementary OS 8 can be installed and set up completely blind, an important win for maintaining your independence as a person with vision disabilities. Danielle Foré Founder & CEO Wed, Jul 3, 2024 7 min read Since the release of OS 8 we’ve been working on things like improving contrast, support for Dark Mode screenshots and brand colors in AppCenter, turning on or snoozing Dark Mode without canceling your schedule, expanding the scope of the “Reduce Motion” setting, and adding more options to reduce distracting notification bubbles. Plus, thanks to feedback from Aaron who you may know from his blog series on Linux accessibility, Notifications and the Shortcut Overlay both got releases that add screen reader support. As a community that includes folks with a range of disabilities ourselves, we’re deeply invested in improving access to Open Source software. We succeed at our mission when we build open computing experiences that are available regardless of ability and fail when accessibility is considered an afterthought or a nice-to-have. This month and always, Inclusive Design is at the core of what we do and we will continue to strive towards that ideal. If you want to follow along or help us address accessibility issues in elementary OS, we’d love your help! We’re tracking issues in this GitHub project. If you discover a new issue—accessibility related or otherwise—we’d love to get your feedback and we have a handy contributor guide to help you file a report here. Code A big new release of Code is here, thanks primarily to Jeremy. This release closes 19 reported issues including a couple of crashers. The “Open in…” menu is now sorted and includes an option for the Terminal pane. Plus the Terminal pane now follows Natural Copy/Paste settings from the Terminal app. The Vala symbols pane now shows a lot more information about symbols in their tooltips. Numbered lists are now handled correctly by the Markdown plugin. The Highlight Word Selection plugin now works with selections of more than one word. Several enhancements were made to managing git branches including sorting branch names alphabetically, the ability to switch to remote branches, and you’ll now be asked how to handle uncommitted changes when switching branches. You can now create edit marks by clicking in the source view gutter. They can be jumped between via the context menu or with the keyboard shortcuts Alt + ← / →. If you’re using the Flatpak version of Code on another OS, the “Open in…” menu is no longer empty and operations that require a network should now work. Plus performance was improved in several cases. Window Manager & Dock This month Leonhard and Leo closed another 19 issue reports in our window manager, including several issues related to multi-monitor, the Multitasking View, and Dock behavior. A crash that could occur when closing LibreOffice windows was fixed. Picture-in-picture will now select the correctly window when its area selection is drawn over an app’s shadow. Non-flatpak apps that don’t correctly match their launchers can now sometimes be matched by the Dock anyways. If you have “activate hotcorners in fullscreen” turned on, you can also now access the Applications Menu with Super while playing a fullscreen game, for example. Plus we made some performance improvements to drawing shadows. System Settings In Keyboard → Shortcuts → Custom you can now choose from a list of installed apps and their actions—in addition to being able to execute custom commands—thanks to Leo. This makes it super straightforward to add a keyboard shortcut for your most common workflows like composing a new email or adding a new Calendar event. You can now create custom keyboard shortcuts for apps and their actions System Settings will also now warn you if your desired keyboard shortcut conflicts with a common system shortcut like “Copy”, “Paste”, or “New Tab”. Plus we fixed an issue that would prevent certain Housekeeping configurations from running, and the “Automatic” accent color option now works more reliably. And More The Screencast Portal now features an improved design for selecting which display or window should be captured, as well as respecting options for capturing the pointer. Plus we fixed issues that prevented screenshots from including window shadows in some cases, and screenshot notifications now open the Image Viewer when clicked. Screencasts portal has a new design Jeremy fixed a number of issues in the latest release of Files including issues related to file renaming, drag-and-drop, ejecting removable drives, and an issue activating context menus from certain parts of the sidebar. And he also fixed an issue preventing bluetooth file sharing from working. Plus, Leo made sure that panel transparency and orientation lock settings get synced to the Login & Lock screen. Get These Updates As always, pop open System Settings → System on elementary OS 8 and hit “Update All” to get these updates plus your regular security, bug fix, and translation updates. Or set up automatic updates and get a notification when updates are ready to install! Early Access Bluetooth Settings got a redesign and a reworking of its list sorting logic that should improve performance, reliability, and its screen reader experience. Especially of note, we now sort out more bluetooth devices so the list of nearby devices should be more concise and useful. Plus we fixed a few issues related to devices that require a passcode to pair, like some keyboards. This includes some fairly large changes so we could really use help testing for regressions before releasing this update for everyone. Bluetooth settings has a new design We’re also now building daily ARM64 Native images thanks to new contributer NN708. This is a universal ARM UEFI image, which means it should be a single image that runs on platforms like Raspberry Pi, Pinebook Pro, and Apple M-series Macs. This makes it a lot simpler for us to support ARM processors in future releasses of elementary OS. Please test these images on your ARM devices and report back! We now include additional processor architecture options in our issue report template to track any problems you experience.

Questionable puns aside, it’s Pride Month and we’re excited to celebrate by bringing you these updates hand-made by real LGBTQIA+ community members from around the world!—and possibly some straight cis folks too. This rainbow of releases includes some important accessibility updates, tons of bug fixes, and of course a few new features. Window Manager & Dock Another absolutely massive release of our window manager is out that fixes about 20 reported issues and a brand new Gesture Controller thanks to Leonhard and Leo. You can now Swipe up in Multitasking View to close windows, app titles in Multitasking View are now always shown—making them accessible for touch screen setups—and screenshots taken with a keyboard shortcut will send a notification that you can use to view it in Files, just to name a few headlining features. If you want to read the full release notes, Good Luck Babe they’re quite long. A new release of our Dock is also out which brings back a couple of old Plank features: showing multiple dots for apps with multiple running windows and cycling through app windows when you hold a drag-n-drop over its icon. Plus you can now open context menus with a long-press. And there’s a number of bug fixes including things related to hide modes and memory usage. Thanks again to Leo and Leonhard for their hard work here. System Settings Leonhard fixed a crash when setting custom hotcorner commands and we now only show the Applications Menu hotcorner action in its corresponding panel corner—that’s top-left for folks reading left-to-right and top-right for folks reading right-to-left. Plus there’s a new option to enable hotcorners even while an app is fullscreened. As a follow up to last month’s fixes, choosing light or dark mode in System Settings will now properly snooze your schedule instead of disabling it all together—a great convenience for those of us who suffer from eye strain or headaches and need to occasionally reach for that dark mode during the day. Plus, the Reduce Motion setting now covers a whole new range of animations—perfect for folks who get motion sick or find animations distracting. Leonardo tackled a couple of crashes in Display settings including one when mirroring, and another when new displays are attached while System Settings is open. We fixed an issue that prevented CalDAV accounts from connecting in Online Accounts settings. And Alain snuck in a few design tweaks, fixing button alignments etc. And More Thanks to feedback from Aaron, Notifications and the Shortcut Overlay both got releases that add screen reader support. Corentin addressed some Flatpak sandbox issues with an updated Apparmor Profile—especially notable if you’d had trouble with Steam. We now use BeaconDB as our location services provider. And thanks to Ryo we’re now shipping the latest version of GNOME Web which brings improved performance and web compatibility as well as a redesigned bookmarks sidebar. Get These Updates As always, pop open System Settings → System on elementary OS 8 and hit “Update All” to get these updates plus your regular security, bug fix, and translation updates. Or set up automatic updates and get a notification when updates are ready to install! Community Pride I want to take a little space to say that our community is for everyone regardless of gender or sexual identity. We’ve long been made up of lots of different kinds of folks and I’m really proud of that. Open Source software should never be a space that is restricted to a narrow set of identities. In a time where many companies are withdrawing their support for the LGBTQIA+ community, I think it’s incredibly important that we make a strong statement against hate and don’t give in to the pressure to erase queer people in some sad attempt to be “apolitical”. Free Software has always been political, and its politics are freedom and inclusivity and so are ours. Sponsors At the moment we’re at 23% of our monthly funding goal and 336 Sponsors on GitHub!

In mid-March we released a big bug fix update—elementary OS 8.0.1—and since then we’ve been hard at work on even more bug fixes and some new exciting features that I’m excited to share with you today! Read ahead to find out what we’ve released recently and what you can help us test in Early Access. Quick Settings Quick Settings has a new “Prevent Sleep” toggle Leo added a new “Prevent Sleep” toggle. This is useful when you’re giving a presentation or have a long-running background task where you want to temporarily avoid letting the computer go to sleep on its normal schedule. We also fixed a bug where the “Dark Mode” toggle would cancel the dark mode schedule when used. We now have proper schedule snoozing, so when you manually toggle Dark Mode on or off while using a timed or sunset-to-sunrise schedule, your schedule will resume on the next schedule change instead of being canceled completely. Vishal also fixed an issue that caused some apps to report being improperly closed on system shutdown or restart and on the lock screen we now show the “Suspend” button rather than the “Lock” button. System Settings Locale settings has a fresh layout thanks to Alain with its options aligned more cleanly and improved links to additional settings. Locale Settings has a more responsive design We’ve also added the phrase “about this device” as a search term for the System page and improved interface copy when a restart is required to finish installing updates based on your feedback. Plus, Stanisław improved stylus detection in Wacom settings preventing a crash when no stylus is found. AppCenter We now show a small label next to the download button for apps which contain in-app purchases. This is especially useful for easily identifying free-to-play games or alt stores like Steam or Heroic Games Launcher. AppCenter now shows when apps have in-app purchases Plus, we now reload app icons on-the-fly as their data is processed, thanks to Italo. That means you’ll no longer get occasionally stuck with an AppCenter which shows missing images for app’s who have taken a bit longer than usual to load. Get These Updates As always, pop open System Settings → System on elementary OS 8 and hit “Update All” to get these updates plus your regular security, bug fix, and translation updates. Or set up automatic updates and get a notification when updates are ready to install! Early Access Our development focus recently has been on some of the bigger features that will likely land for either elementary OS 8.1 or 9. We’ve got a new app, big changes to the design of our desktop itself, a whole lot of under-the-hood cleanup, and the return of some key system services thanks to a new open source project. Monitor We’re now shipping a System Monitor app by default By popular demand—and thanks to the hard work of Stanisław—we have a new system monitor app called “Monitor” shipping in Early Access. Monitor provides usage information for your processor, GPU, memory, storage, network, and currently running processes. You can optionally see system information in the panel with Monitor You can also optionally get a ton of glanceable information shown in the panel. There’s currently a lot of work happening to port Monitor to GTK4 and improve its functionality under the Secure Session, so make sure to report any issues you find! Multitasking The Dock is getting a workspace switcher Probably the biggest change to the Pantheon shell since its early inception, the Dock is getting a new workspace switcher! The workspace switcher works in a familiar way to the one you may have seen in the Multitasking View: Your currently open workspaces are represented as tiles with the icons of apps running on them; You can select a workspace to switch to it; You can drag-and-drop workspaces to rearrange them; And you can use the “+” button to create a new blank workspace. One new trick however is that selecting the workspace you’re already on will launch Multitasking View. The new workspace switcher makes it so much more accessible to multitask with just the mouse and get an overview of your workflows without having to first enter the Multitasking View. We’re really excited to hear what people think about it! You can close apps from Multitasking View by swiping up Another very satisfying feature for folks using touch input, you can now swipe up windows in the Multitasking View to close them. This is a really familiar gesture for those of us with Android and iOS devices and feels really natural for managing a big stack of windows without having to aim for a small “x” button. GTK4 Porting We’ve recently landed the port of Tasks to GTK4. So far that comes with a few fixes to tighten up its design, with much more possible in the future. Please make sure to help us test it thoroughly for any regressions! Tasks has a slightly tightened up design We’re also making great progress on porting the panel to GTK4. So far we have branches in review for Nightlight, Bluetooth, Datetime, and Network indicators. Power, Keyboard, and Quick Settings indicators all have in-progress branches. That leaves just Applications, Sound, and Notifications. So far these ports don’t come with major feature changes, but they do involve lots of cleaning up and modernizing of these code bases and in some cases fixing bugs! When the port is finished, we should see immediate performance gains and we’ll have a much better foundation for future releases. You can follow along with our progress porting everything to GTK4 in this GitHub Project. And More When you take a screenshot using keyboard shortcuts or by secondary-clicking an app’s window handle, we now send a notification letting you know that it was succesful and where to find the resulting image. Plus there’s a handy button that opens Files with your screenshot pre-selected. We’re also testing beaconDB as a replacement for Mozilla Location Services (MLS). If you’re not aware, we relied on MLS in previous versions of elementary OS to provide location information for devices that don’t have a GPS radio. Unfortunately Mozilla discontinued the service last June and we’ve been left without a replacement until now. Without these services, not only did maps and weather apps cease to function, but system features like automatic timezone detection and features that rely on sunset and sunrise times no longer work properly. beaconDB offers a drop-in replacement for MLS that uses Wireless networks, bluetooth devices, and cell towers to provide location data when requested. All of its data is crowd-sourced and opt-in and several distributions are now defaulting to using it as their location services data provider. I’ve set up a small sponsorship from elementary on Liberapay to support the project. If you can help support beaconDB either by sponsoring or providing stumbler data, I’d highly encourage you to do so!

It’s been a little over 100 days since elementary OS 8 was released, and we’re proud to announce another round of updates, including a fresh new download. We’ve been hard at work this winter addressing issues that you reported and we’ve added a couple new creature comforts along the way. This bug fix release also includes the latest Ubuntu LTS Hardware Enablement Kernel, so it’s worth checking out if you downloaded OS 8.0 and it disagreed with your hardware. AppCenter We now properly use dark mode brand colors and dark mode screenshots thanks to Italo. Plus, when developers provide screenshots for multiple desktop environments, we now prefer the ones intended for our desktop environment, Pantheon. We support the new <Developer> Appstream tag, thanks to Juan. And we now support the contribute URL type. AppCenter now shows dark mode screenshots when available Italo also fixed some issues with release notes overflowing out of their container, and we slightly redesigned the release notes window in the Updates page. He also addressed a few other issues in the Updates page that could occur while things were being updated or refreshed and made sure AppCenter recovers gracefully when its cache is emptied. Release notes dialogs have been slightly redesigned Search is also much faster thanks to Leonhard. And for developers, Ryo fixed loading your local metadata for testing with the --load-local terminal option. Files & Terminal Jeremy fixed another half-dozen reported issues in Files, including an issue that prevented entering file paths in search mode, an issue that prevented scrolling after deleting files, and an issue where files would disappear when dropped on an unmounted drive. The New file submenu now respects the hierarchy of folders in Templates. We now also respect the admin:// uri protocol for opening a path as an administrator, and Files is now styled correctly when run as administrator. He also fixed an issue where Terminal tabs took multiple clicks to focus, and an issue where keyboard shortcuts stopped working for tabs that had been dragged into their own new window. Plus, file paths and names are also now properly quoted when drag-and-dropped from Files into Terminal. System Settings System Settings now allows configuring its notifications in System Settings → Notications. So you can turn off bubbles if you don’t want to receive notifications about updates, for example. We’ll also no longer automatically download updates when on metered connections and send a notification instead, thanks to Leonhard. Plus we no longer check for updates in Demo Mode. Updates now show their download size and you can see progress towards our monthly sponsorship goal In System, Vishal made sure we show how large an update will be before downloading it and that we skip held-back packages—such as phased or staged updates—when preparing the updates bundle so that it will more reliably succeed. Alain added a progress bar while downloading. And Ryo made sure the last refresh time is more accurate when no updates are available. Alain also added a new progress bar that represents how close we are to meeting our monthly sponsorship goal. In Applications, you can now disallow notifications access. This is especially useful for apps which use the notifications portal, but don’t properly report their notification usage and can’t be controlled in the Notifications settings page. Reign in apps that don’t appear in Notifications settings In Network there are two new settings: whether a network should be automatically connected to when available and whether to reduce background data usage when connected to that network. Disable autoconnect or mark a network as metered We also updated the pointer icons in Mouse & Touchpad settings and the checkmarks in Locale settings will now respect your chosen accent color. Plus settings pages with sidebars now remember the width you adjusted them to, thanks to Alain. Installation & Onboarding David fixed a crash with certain partitioning schemes in the Installer’s custom install view. And the Encryption step was redesigned to fit on a single page, solving an issue with confusing navigation. Plus, onboarding will now always stay centered on the screen, even when resized. Panel & Quick Settings Ilya fixed an issue with the panel height when using the Classic session and HiDPI displays. The app context menu in the Applications menu now shows a “Keep in Dock” checkbox, just like in the Dock thanks to Stella. In the Power menu, we now show the device model if available, and avoid erroneously showing an empty battery icon thanks to Alain. In the Sound menu, Dmitry fixed loading album art from certain apps like Google Chrome, and we fixed an issue where player icons could become too large. See who else is logged in and quickly switch accounts from Quick Settings In Quick settings, Leonhard fixed an issue with performing updates while shutting down. And Alain added a new page where you can see which other people are logged in and quickly switch between accounts. Dock Leo added a bit more spacing between launchers and their running indicators, and fixed an issue where larger icons could be clipped at the peak of their bounce animation. Apps who don’t notify on startup will no longer bounce in the dock indefinitely, thanks to Leonhard. We fixed an issue where the dock would still receive click events while hidden in the Classic session. Plus the dock now has an opaque style when “Panel Translucency” is turned off in System Settings → Desktop → Dock & Panel. Window Manager We have another huge release of our window manager thanks to Leonhard and Leo. This release fixes five potential crashes, over a dozen reported issues, fixes related to both the Classic and Secure sessions, issues related to HiDPI, and more, plus performance improvements. It’s worth reading the full release notes on GitHub if you have been waiting for the fix for a specific issue. And More OS 8.0.1 includes the latest long-term support Hardware Enablement stack from Ubuntu, including Linux 6.11. This brings improved performance for AMD processors, support for Intel “Lunar Lake” processors, and filesystem performance improvements in some cases. Plus support for certain webcams, USB network devices, joysticks, and more. Leo fixed an issue where connecting Bluetooth devices could cause the Lock Screen to freeze. You can now close the captive network assistant with the keyboard shortcut Ctrl + Q, thanks to Stanisław. And Alain fixed copying screenshots to the clipboard. We fixed an issue where wired network connections could fail to connect due to a change in Ubuntu. We’re pursuing this issue upstream and working on a way to ship the fix as an update, but for now fixing this issue requires either manual intervention through Terminal or a reinstall. We also now pre-install an AppArmor profile that fixes a number of Flatpak-related issues like not being to install certain runtime updates or apps not launching in the guest session or Demo mode. Special thanks to Uncle Tallest for investigating this issue and helping folks in our Discord who ran into it. And of course this release comes with a ton of translation updates! Special thanks to our hard-working internationalization community and especially Ryo who fixed a number of issues with things that couldn’t be localized properly in the previous release. Get elementary OS 8.0.1 elementary OS 8.0.1 is available as a pay-what-you-can purchase at elementary.io today. Localized direct downloads and a torrent magnet link are provided.

It’s only been a little over 2 weeks since we released elementary OS 8, but we’re already back with updates just in time for the holidays! Terminal The headliner this month is Terminal which comes with a bunch of fixes and new features thanks to Jeremy. It now uses the more modern tab bar widget you’re used to from Web, Files, and Code. There’s an overlay bar that shows the current zoom level when it changes. We do a better job of handling URIs which contain spaces. And we now show unsafe paste warnings for Drag n Drop operations. Plus, we now show the unsafe paste warning for more commands like doas thanks to Elsie and there’s a new option in the gear menu to toggle unsafe paste alerts thanks to Stella and Charlie. Michal upped the contrast for gray in our default style and Igor made sure we focus the relevant tab when notifications are clicked. Plus, we now replace notifications from the same tab and withdraw notifications when a tab is focused, so your notification center should be a lot less noisy. This release was really a group effort with several new contributors, so major shoutouts to everyone who worked on it! AppCenter AppCenter will use Dark Mode screenshots when available Thanks to Italo, AppCenter will now use provided dark mode screenshots and brand colors when developers provide them. Plus, he addressed a visual bug with release notes. And Juan added support for the latest Appstream Developer tag, so we’re staying up on standards. Window Manager & Dock In the Window Manager, Leo fixed an issue where the dock could sometimes still be clicked when hidden in the Classic session, while Leonhard contributed some performance improvements. In the Dock, Leonhard made sure launcher bounces don’t run too long for apps that don’t notify on startup. Leo fixed an issue where launchers with large icons could become clipped while they bounce and made sure running indicators have a bit more room to breath. Plus the dock now also respects the “Panel Translucency” setting, making it completely solid when requested for added contrast. System Settings Alain added some visual polish to the System view as well as a new progress bar that represents how close we are to meeting our monthly sponsorship goal. Plus Leonhard made sure automatic updates won’t download on metered networks, and we avoid checking for system updates altogether in Demo Mode. We now show monthly funding goal progress right in System Settings You can now prevent Apps from sending notifications from Applications → Permissions, even for apps that don’t report their notification usage in Notification settings. and the check mark next to the current language in Language & Region settings will now follow your accent color thanks to Leo. Installation & Onboarding David fixed a crash with certain partitioning schemes in the Installer’s custom install view, and the encrypt view was simplified. Onboarding will now always stay centered on the screen, even when resized. Icon Browser A new version of the Icon Browser for app developers is available in AppCenter that includes the latest icons for Platform 8 as well as a quick button for copying code snippets thanks to Ryo. And we now focus the search automatically when you start typing, thanks to Alain. And More You can now close the captive network assistant with the keyboard shortcut Ctrl + Q, thanks to Stanisław. Alain fixed copying screenshots to the clipboard. And there a ton of translation updates, especially including traditional Chinese thanks to Kisaragi.

I've never seen so many developers curious about leaving the Mac and giving Linux a go. Something has really changed in the last few years. Maybe Linux just got better? Maybe powerful mini PCs made it easier? Maybe Apple just fumbled their relationship with developers one too many times? Maybe it's all of it. But whatever the reason, the vibe shift is noticeable. This is why the future is so hard to predict! People have been joking about "The Year of Linux on the Desktop" since the late 90s. Just like self-driving cars were supposed to be a thing back in 2017. And now, in the year of our Lord 2025, it seems like we're getting both! I also wouldn't underestimate the cultural influence of a few key people. PewDiePie sharing his journey into Arch and Hyprland with his 110 million followers is important. ThePrimeagen moving to Arch and Hyprland is important. Typecraft teaching beginners how to build an Arch and Hyprland setup from scratch is important (and who I just spoke to about Omarchy). Gabe Newell's Steam Deck being built on Arch and pushing Proton to over 20,000 compatible Linux games is important. You'll notice a trend here, which is that Arch Linux, a notoriously "difficult" distribution, is at the center of much of this new engagement. Despite the fact that it's been around since 2003! There's nothing new about Arch, but there's something new about the circles of people it's engaging. I've put Arch at the center of Omarchy too. Originally just because that was what Hyprland recommended. Then, after living with the wonders of 90,000+ packages on the community-driven AUR package repository, for its own sake. It's really good! But while Arch (and Hyprland) are having a moment amongst a new crowd, it's also "just" Linux at its core. And Linux really is the star of the show. The perfect, free, and open alternative that was just sitting around waiting for developers to finally have had enough of the commercial offerings from Apple and Microsoft. Now obviously there's a taste of "new vegan sees vegans everywhere" here. You start talking about Linux, and you'll hear from folks already in the community or those considering the move too. It's easy to confuse what you'd like to be true with what is actually true. And it's definitely true that Linux is still a niche operating system on the desktop. Even among developers. Apple and Microsoft sit on the lion's share of the market share. But the mind share? They've been losing that fast. The window is open for a major shift to happen. First gradually, then suddenly. It feels like morning in Linux land!
Snippets are a useful addition to Svelte 5. I use them in my Svelte 5 projects like Edna. Snippet basics A snippet is a function that renders html based on its arguments. Here’s how to define and use a snippet: {#snippet hello(name)} <div>Hello {name}!</div> {/snippet} {@render hello("Andrew")} {@render hello("Amy")} You can re-use snippets by exporting them: <script module> export { hello }; </script> {@snippet hello(name)}<div>Hello {name}!</div>{/snippet} Snippets use cases Snippets for less nesting Deeply nested html is hard to read. You can use snippets to extract some parts to make the structure clearer. For example, you can transform: <div> <div class="flex justify-end mt-2"> <button onclick={onclose} class="mr-4 px-4 py-1 border border-black hover:bg-gray-100" >Cancel</button > <button onclick={() => emitRename()} disabled={!canRename} class="px-4 py-1 border border-black hover:bg-gray-50 disabled:text-gray-400 disabled:border-gray-400 disabled:bg-white default:bg-slate-700" >Rename</button > </div> into: {#snippet buttonCancel()} <button onclick={onclose} class="mr-4 px-4 py-1 border border-black hover:bg-gray-100" >Cancel</button > {/snippet} {#snippet buttonRename()}...{/snippet} To make this easier to read: <div> <div class="flex justify-end mt-2"> {@render buttonCancel()} {@render buttonRename()} </div> </div> snippets replace default <slot/> In Svelte 4, if you wanted place some HTML inside the component, you used <slot />. Let’s say you have Overlay.svelte component used like this: <Overlay> <MyDialog></MyDialog> </Overlay> In Svelte 4, you would use <slot /> to render children: <div class="overlay-wrapper"> <slot /> </div> <slot /> would be replaced with <MyDialog></MyDialog>. In Svelte 5 <MyDialog></MyDialog> is passed to Overlay.svelte as children property so you would change Overlay.svelte to: <script> let { children } = $props(); </script> <div class="overlay-wrapper"> {@render children()} </div> children property is created by Svelte compiler so you should avoid naming your own props children. snippets replace named slots A component can have a default slot for rendering children and additional named slots. In Svelte 5 instead of named slots you pass snippets as props. An example of Dialog.svelte: <script> let { title, children } = $props(); </script> <div class="dialog"> <div class="title"> {@render title()} </div> {@render children()} </div> And use: {#snippet title()} <div class="fancy-title">My fancy title</div> {/snippet} <Dialog title={title}> <div>Body of the dialog</div> </Dialog> passing snippets as implicit props You can pass title snippet prop implicitly: <Dialog> {#snippet title()} <div class="fancy-title">My fancy title</div> {/snippet} <div>Body of the dialog</div> </Dialog> Because {snippet title()} is a child or <Dialog>, we don’t have to pass it as explicit title={title} prop. The compiler does it for us. snippets to reduce repetition Here’s part of how I render https://tools.arslexis.io/ {#snippet row(name, url, desc)} <tr> <td class="text-left align-top" ><a class="font-semibold whitespace-nowrap" href={url}>{name}</a> </td> <td class="pl-4 align-top">{@html desc}</td> </tr> {/snippet} {@render row("unzip", "/unzip/", "unzip a file in the browser")} {@render row("wc", "/wc/", "like <tt>wc</tt>, but in the browser")} It saves me copy & paste of the same HTML and makes the structure more readable. snippets for recursive rendering Sometimes you need to render a recursive structure, like nested menus or file tree. In Svelte 4 you could use <svelte:self> but the downside of that is that you create multiple instances of the component. That means that the state is also split among multiple instances. That makes it harder to implement functionality that requires a global view of the structure, like keyboard navigation. With snippets you can render things recursively in a single instance of the component. I used it to implement nested context menus. snippets to customize rendering Let’s say you’re building a Menu component. Each menu item is a <div> with some non-trivial children. To allow the client of Menu customize how items are rendered, you could provide props for things like colors, padding etc. or you could allow ultimate flexibility by accepting an optional menuitem prop that is a snippet that renders the item. You can think of it as a headless UI i.e. you provide the necessary structure and difficult logic like keyboard navigation etc. and allow the client lots of control over how things are rendered. snippets for library of icons Before snippets every SVG Icon I used was a Svelte component. Many icons means many files. Now I have a single Icons.svelte file, like: <script module> export { IconMenu, IconSettings }; </script> {#snippet IconMenu(arg1, arg2, ...)} <svg>... icon svg</svg> {/snippet}} {#snippet IconSettings()} <svg>... icon svg</svg> {/snippet}}
I realize that for all I've talked about Logic for Programmers in this newsletter, I never once explained basic logical quantifiers. They're both simple and incredibly useful, so let's do that this week! Sets and quantifiers A set is a collection of unordered, unique elements. {1, 2, 3, …} is a set, as are "every programming language", "every programming language's Wikipedia page", and "every function ever defined in any programming language's standard library". You can put whatever you want in a set, with some very specific limitations to avoid certain paradoxes.2 Once we have a set, we can ask "is something true for all elements of the set" and "is something true for at least one element of the set?" IE, is it true that every programming language has a set collection type in the core language? We would write it like this: # all of them all l in ProgrammingLanguages: HasSetType(l) # at least one some l in ProgrammingLanguages: HasSetType(l) This is the notation I use in the book because it's easy to read, type, and search for. Mathematicians historically had a few different formats; the one I grew up with was ∀x ∈ set: P(x) to mean all x in set, and ∃ to mean some. I use these when writing for just myself, but find them confusing to programmers when communicating. "All" and "some" are respectively referred to as "universal" and "existential" quantifiers. Some cool properties We can simplify expressions with quantifiers, in the same way that we can simplify !(x && y) to !x || !y. First of all, quantifiers are commutative with themselves. some x: some y: P(x,y) is the same as some y: some x: P(x, y). For this reason we can write some x, y: P(x,y) as shorthand. We can even do this when quantifying over different sets, writing some x, x' in X, y in Y instead of some x, x' in X: some y in Y. We can not do this with "alternating quantifiers": all p in Person: some m in Person: Mother(m, p) says that every person has a mother. some m in Person: all p in Person: Mother(m, p) says that someone is every person's mother. Second, existentials distribute over || while universals distribute over &&. "There is some url which returns a 403 or 404" is the same as "there is some url which returns a 403 or some url that returns a 404", and "all PRs pass the linter and the test suites" is the same as "all PRs pass the linter and all PRs pass the test suites". Finally, some and all are duals: some x: P(x) == !(all x: !P(x)), and vice-versa. Intuitively: if some file is malicious, it's not true that all files are benign. All these rules together mean we can manipulate quantifiers almost as easily as we can manipulate regular booleans, putting them in whatever form is easiest to use in programming. Speaking of which, how do we use this in in programming? How we use this in programming First of all, people clearly have a need for directly using quantifiers in code. If we have something of the form: for x in list: if P(x): return true return false That's just some x in list: P(x). And this is a prevalent pattern, as you can see by using GitHub code search. It finds over 500k examples of this pattern in Python alone! That can be simplified via using the language's built-in quantifiers: the Python would be any(P(x) for x in list). (Note this is not quantifying over sets but iterables. But the idea translates cleanly enough.) More generally, quantifiers are a key way we express higher-level properties of software. What does it mean for a list to be sorted in ascending order? That all i, j in 0..<len(l): if i < j then l[i] <= l[j]. When should a ratchet test fail? When some f in functions - exceptions: Uses(f, bad_function). Should the image classifier work upside down? all i in images: classify(i) == classify(rotate(i, 180)). These are the properties we verify with tests and types and MISU and whatnot;1 it helps to be able to make them explicit! One cool use case that'll be in the book's next version: database invariants are universal statements over the set of all records, like all a in accounts: a.balance > 0. That's enforceable with a CHECK constraint. But what about something like all i, i' in intervals: NoOverlap(i, i')? That isn't covered by CHECK, since it spans two rows. Quantifier duality to the rescue! The invariant is equivalent to !(some i, i' in intervals: Overlap(i, i')), so is preserved if the query SELECT COUNT(*) FROM intervals CROSS JOIN intervals … returns 0 rows. This means we can test it via a database trigger.3 There are a lot more use cases for quantifiers, but this is enough to introduce the ideas! Next week's the one year anniversary of the book entering early access, so I'll be writing a bit about that experience and how the book changed. It's crazy how crude v0.1 was compared to the current version. MISU ("make illegal states unrepresentable") means using data representations that rule out invalid values. For example, if you have a location -> Optional(item) lookup and want to make sure that each item is in exactly one location, consider instead changing the map to item -> location. This is a means of implementing the property all i in item, l, l' in location: if ItemIn(i, l) && l != l' then !ItemIn(i, l'). ↩ Specifically, a set can't be an element of itself, which rules out constructing things like "the set of all sets" or "the set of sets that don't contain themselves". ↩ Though note that when you're inserting or updating an interval, you already have that row's fields in the trigger's NEW keyword. So you can just query !(some i in intervals: Overlap(new, i')), which is more efficient. ↩
In the previous article, we peeked at the reset circuit of ESP-Prog with an oscilloscope, and reproduced it with basic components. We observed that it did not behave quite as expected. In this article, we’ll look into the missing pieces. An incomplete circuit For a hint, we’ll first look a bit more closely at the … Continue reading The missing part of Espressif’s reset circuit → The post The missing part of Espressif’s reset circuit appeared first on Quentin Santos.
