We have consistently said that we cannot forsee the deb-based desktop going away. I still can’t see that happening. Debs are an integral part of the way the desktop is built. It’s just not feasible / desirable to make the desktop be “all snap”.

When there are imperfections, we rely on users and our active community to tell us how the software is not working correctly, so we can fix it. The way we do that, and have done for 15 years now, is via bug reports. Discussion is great, but detailed bug reports are better for letting developers know what’s wrong.

but that doesn’t mean that confining applications is not a benefit also to FOSS applications, security is an issue that needs to be addressed with many layers of measures no mater what licensing approach you use to license the software

The benefits for developers do reflect on benefits for users, with more software delivered faster and more securely.

But now Chromium is no more available as deb, so what to expect ?

What’s the use of ie. snap libreoffice if it can’t access documents on a samba server in my workplace ? Should I really re-organize years of storage and work in my office for being able to use snap ? A too high price to pay, for the moment.

Disk space is an issue. Resource usage is an issue. Those new packages nowadays need huge amount of storage to finally do the exact same thing as their older and lighter deb counterpart. Whatever the price of storage, it’s the opposite of a progress, it’s not optimal at all.

They may skim books for what they’ll “need to know.” They’re less likely to wonder, say, “How can we be sure that’s true?” than to ask “Is this going to be on the test?”

One lesser-appreciated user-behaviour is when a user would like to choose an alternative download location. On a download link, your user can right-click -> “save link as…” and place the download directly into a folder of their choice. Handy if you want something to go directly to removable media, for example. On a download button, there’s no such option.

You can afford to make a proper PR to upstream.

Can we just forward/bubble all events emitted by the underlying input element?

Can this be merged please, this fixes a problem I have

May I ask what is holding this back?

With some frameworks, you may find your needs at odds with the enterprise-level goals of a megacorp owner, and you may both benefit and sometimes suffer from their web-scale engineering. Svelte’s future does not depend on the continued delivery of business value to one company, and its direction is shaped in public by volunteers.

Magnetic materials are always made of metal, but not all metals are magnetic

I personally think that starting from google's components makes easier to keeping update to material specs updates.

Notably, LLVM and JVM are by far the most prominent targets in this scenario: they’re both open-source and well-documented targets that provide a ton of firepower, and there frankly aren’t a ton of other options.

If the client JS is disabled, then handleSubmit will never be executed and you have to care that your /api/fakeBackendRoute will handle the data exactly how the client would.

emphasizing that 'this' and 'global object' are two different things not only in Node.js but in JavaScript in general

Svelte by itself is great, but doing a complete PWA (with service workers, etc) that runs and scales on multiple devices with high quality app-like UI controls quickly gets complex. Flutter just provides much better tooling for that out of the box IMO. You are not molding a website into an app, you are just building an app. If I was building a relatively simple web app that is only meant to run on the web, then I might still prefer Svelte in some cases.

Fallback values aren't used to fix the browser compatibility. If the browser doesn't support CSS custom Properties, the fallback value won't help.

So if you are designing for an app

There is no rerender, when you call listen, then all scroll events will warn on chrome. See this entry from svelte: breaking the web

After i've stabilized the library i can start to discuss about adding new components and features!

Many of you will not be able to use this if you depend on custom import types or other fancy loaders. This project is just not for you!

GET is the primary mechanism of information retrieval and the focus of almost all performance optimizations.

Never use x && y || z when y can return a non-zero exit status.

I think what the author intended to do was check if the second argument was a non-empty string (which is not the same thing as checking whether there are more than 1 argument, as the second argument could be passed but be the empty string).

However, this construct is not completely equivalent to if ... fi in the general case.

Some people try to use && and || as a shortcut syntax for if ... then ... else ... fi, perhaps because they think they are being clever.

It is open to the community to help set its direction.

In Rust, we use the "No New Rationale" rule, which says that the decision to merge (or not merge) an RFC is based only on rationale that was presented and debated in public. This avoids accidents where the community feels blindsided by a decision.

I'd like to go with an RFC-based governance model (similar to Rust, Ember or Swift) that looks something like this: new features go through a public RFC that describes the motivation for the change, a detailed implementation description, a description on how to document or teach the change (for kpm, that would roughly be focused around how it affected the usual workflows), any drawbacks or alternatives, and any open questions that should be addressed before merging. the change is discussed until all of the relevant arguments have been debated and the arguments are starting to become repetitive (they "reach a steady state") the RFC goes into "final comment period", allowing people who weren't paying close attention to every proposal to have a chance to weigh in with new arguments. assuming no new arguments are presented, the RFC is merged by consensus of the core team and the feature is implemented. All changes, regardless of their source, go through this process, giving active community members who aren't on the core team an opportunity to participate directly in the future direction of the project. (both because of proposals they submit and ones from the core team that they contribute to)

All browers handle 302 incorrectly. Chrome 30, IE10. It became the de facto incorrect implementation; that cannot be changed because so many web-sites issue mistakenly issue 302. In fact ASP.net MVC incorrectly issues 302, depending on the fact that browsers handle it incorrectly.

Tell you why tree-shaking fails, if it does.

What it doesn't do

But using internal api's is dangerous as these may change when you update svelte. If you decide to use this, add a line to your project Readme.md mentioning which internal api's you used and why. Try to write it using other methods when you can.

I see this issue has 2 open PR's is this going to be finalized anytime soon?

Furthermore, how come there's a PR open since 3 months, at what seems to be the authoritative repo for Svelte?

This is Sass based, and therefore doesn't require Svelte components

This is not an MDC Web component. It is an addition that SMUI provides.

Feel free to subscribe to the issue (there's button in the right hand column) but do not comment unless you are adding value to the discussion. "Me too" and "+1" are not valuable, nor are use cases that have already been written in the comments (e.g., we know that you can't put <tr> or <dd> elements with a <div>).

Note that when using sass (Dart Sass), synchronous compilation is twice as fast as asynchronous compilation by default, due to the overhead of asynchronous callbacks.

When you do import '../scss/application.scss', you're telling webpack to include application.scss in the build. This does not mean it's going to be compiled into your javascript, only that webpack now compiles and knows how to load this file.

Some of the verbs implemented by systemctl are designed to provide a high-level overview in a human readable format. All that information is available over dbus, and/or journalctl, systemctl show. We could provide that information in json format, but there's a second problem. Information and format of information printed by e.g. systemctl status is not stable. Since the output is not suitable for programmatic consumption anyway, there's no need to provide it in a machine readable format.

I came up with this solution by piecing together man pages and random google result. I was surprised at how many incomplete and inaccurate answers were out there. What may have been more surprising was the complete lack of a full intact solution.

I don't think the heading/bearing split is as clear-cut as that.

In summary TLS uses PKI to secure information over the internet. However, it is important to note that TLS supports other encryption standards which are not part of PKI.

is this solution considered a hack or is something that we can use as an approved workaround in scenarios where we need to manually trigger validations?

Library author here. I'm always fascinated by new ways people can invalidate my assumptions. I mean that in a sincerely positive way, as it results in learning.

Ok, I have seen that there are lot of built-in and third party validations, but sooner or later I will face a validation rule not covered by this buffet. Can I build a custom one? Of course you can!

Of course you can start implementing your own thing, but you will waste a lot of precious time reinventing the wheel. Why not take advantage of a validation library that takes care of all this complexity for you?

You can try to build a solution to tackle these issues on your own, but it will cost you time and money... why not use a battle-tested solution to handle all this complexity?

Logistically speaking, I suppose "depender" and "dependee" would be more accurate, though neither of those are proper english words as far as I know.

In the context of software engineering, I've always used "dependent" and "dependee".

We don’t need to apply refactorings we don’t want.

This does solve the problem, but now our project and API is structured differently. In large projects it might be very hard to determine how to pull this trick off, or even impossible!

Especially when rollup is configured with multiple outputs, I find this particular onwarn to be helpful in reducing warning clutter. It just displays each circular reference once and doesn't repeat the warning for each output:

I think my personal preference would be to see them all at once. Or maybe limit it to up to 10 messages and then list the count of how many more messages were not displayed. Pick your reaction

Another thing we could do to limit output would be to only every show the first circular dependency warning. I think we already do this for other types of warnings. Then you would need to tackle the warnings one-by-one, though.

These are fine and do not cause any issues.

Why will you children insist on giving parties!”

Note that these are not hyperlinks; these URIs are used for identification. This is a machine-readable way to say “this is HTML”. In particular, software does not usually need to fetch these resources, and certainly does not need to fetch the same one over and over!

if you’re just the casual web surfer type, learning about Internet terminology might not be of much real use to you

Wondering how to get field state from multiple fields at once? People coming from Redux-Form might be wondering where the equivalent of Redux Form's Fields component is, as a way to get state from several fields at once. The answer is that it's not included in the library because it's so easy to write one recursively composing Field components together.

I’ll try to answer them over email and I may publish them here, with your approval.

However, objects are generally easier to work with than maps, because not all JavaScript functions, frameworks, and libraries support maps. For example, the JSON.stringify() function doesn't serialize maps by default.

Windows: Shift + Delete

Once again, this isn’t good or bad, it’s just the most efficient way to create something that is similar to something else

This isn’t to say that multiplying code is good or bad – it’s a characteristic of all code regardless of quality.

For years, I’ve shared with friends and clients what I call the bunny theory of code. The theory is that code multiplies when you’re not looking, not unlike bunnies that tend to multiply when you’re not looking.

just saying that if you're going to try to go with a markup approach, at least go all the way, instead of the frankenstein that is JSX

I'm okay with an overall design that allows people to plugin the parts they need in order to be able to generically support a compile-to-javascript language, but to bake in support for one singular solution because its popular is simply bad engineering.

Of all the compile-to-languages, the one that strikes me as having the least merit is JSX. It's basically a ton of added complexity for the sake of what boils down to syntax. There are no real gains in terms of language semantics in JSX.

Yes, you can embed loops in it and compose lots of small repeated JSX snippets, but that almost never happens in practice because mixing the turing complete of javascript with the markup of HTML eliminates the readability of JSX so that it is actually harder to parse than a solution like hyperscript (the syntactical approach taken by virtual-dom).

Without elegant ways of expressing loops/iterators (like angular does with directives), the primary way to keep JSX readable thus becomes copying and pasting.

The react community has become a big cargo cult. There are some good ideas in the community and many Bad Ideas™. Paving the bad idea cowpaths lends a sense of legitimacy to these bad technical ideas that is not merited.

I agree that "it feels gross" is a bad reason. "not paving a bad cowpath" is a much better reason.

hyperscript is much simpler to refactor and DRY up your code than with JSX, because, being vanilla javascript, its easier to work with variable assignment, loops and conditionals.

The only "issue" it has is that its unfamiliar. People have been working with HTML for years and are comfortable with it. That's basically the only reason that people find it more readable. If you make an effort to spend sometime with hyperscript, it becomes as familiar and readable as jsx.

Other frameworks, which use a template syntax built atop HTML — Svelte, Vue, Ractive, Glimmer etc — have historically been fragmented, meaning those tools need to be reinvented many times.

However, in function components there really isn't much need for this pattern since you can just use JS default arguments

Good risk management is inherently simple; adding too many complexities increases the likelihood of overlooking the obvious.

Node doesn't have a DOM available. So in order to render HTML we use string concatenation instead. This has the fun benefit of being quite efficient, which in turn means it's great for server rendering!

Why not just use that instead of inventing a syntax that's not part of ECMAScript?

Why not Template Literals?

This is a very dangerous practice as each optimization means making assumptions. If you are compressing an image you make an assumption that some payload can be cut out without seriously affecting the quality, if you are adding a cache to your backend you assume that the API will return same results. A correct assumption allows you to spare resources. A false assumption introduces a bug in your app. That’s why optimizations should be done consciously.

Moreover, React team even removed the “highlight updates” feature from dev tools because people used to obsessively haunt wasted renders with no reasoning behind it

In the vast majority of cases there’s nothing wrong about wasted renders. They take so little resources that it is simply undetectable for a human eye. In fact, comparing each component’s props to its previous props shallowly (I’m not even talking about deeply) can be more resource extensive then simply re-rendering the entire subtree.

"The Map is not the territory" —Alfred Korzybski

Alfred Korzybski remarked that "the map is not the territory" and that "the word is not the thing", encapsulating his view that an abstraction derived from something, or a reaction to it, is not the thing itself.

"The menu is not the meal."

A map is not the territory it represents, but, if correct, it has a similar structure to the territory, which accounts for its usefulness.

Every new variation to the view requires updating both the view model and the template. This holds true even for simple variations.

Our custom useEffect is not idiomatic Svelte.

Beautiful, except that switching albums does not update the PhotoGrid. This is not the automatic reactivity we were promised by Svelte.

I'm not sure I understand the problem, everything you are describing is already possible.

Disclaimer: I’m new to Svelte so this isn’t so much a recommendation as it is a “I guess this is a way to do it 🤷‍♂️”

Why struggle with custom Syntax DSLs when you can use one so widely supported?

JSX is an XML-like syntax extension to EcmaScript (https://facebook.github.io/jsx/). It is not a language or runtime.

Unfortunately people lack the the time to invest to really understand those things

People constantly suggest that I should have just worked with a different library instead of writing another one.

If you are interested in a library that has the discipline of React, transparent implementation that doesn't cut corners for easiness, and all the performance to back it up maybe SolidJS is the library for you.

Very few were interested in furthering the platform in the places they just took for granted.

Always fascinated to discover a use case I'd never have considered.

Class participation vs. attending class.The quantity andquality of online class participation replaces on-siteattendance

But maybe this PR should still be merged until he finds time for that?

I created a pull request to have the if (node.parentNode) conditional added to detach. It was not applied due to the desire to find the root cause of the <meta> tag manifestation of this issue.

I don't think we need more tooling here.

Unfortunately, this only worked because of a feature called import elision. When TypeScript outputs JavaScript files, it sees that Options is only used as a type, and it automatically drops its import. The resulting output looks kind of like this:

The onBlur function can take a SyntheticFocusEvent like it would if you had given it directly to an <input/> component, but you can also just call it: props.input.onBlur() to mark the field as blurred (inactive).

To be clear, I have a reasonable workaround. I'd only like it to be less difficult to discover. At a minimum, this issue should help others find it...

You probably want initialValue! ⚠️ The value of the field upon creation. This value is only needed if you want your field be dirty upon creation (i.e. for its value to be different from its initial value).

The problem I have with this approach to state and prop variables is that the difference between them is very blurry. In React you can clearly see that a prop is an input to component (because of clear function notation), and that state is something internal. In Svelte they are both just variables, with the exception that props use export keyword.

Because Svelte is a compiler, we're not bound to the peculiarities of JavaScript: we can design a component authoring experience, rather than having to fit it around the semantics of the language.

Insisting on a specific implementation, rather than proposing a clear problem, suggesting a possible solution, and “not being married” to your initial preferred solution.

In my opinion, because Webpack was one of the first bundlers, is heavily packed with features, and has to support swathes of legacy code and legacy module systems, it can make configuring Webpack cumbersome and challenging to use. Over the years, I’ve written package managers, compilers, and bundlers, and I still find configuring Webpack to be messy and unintuitive.

But this is only a halfway decent way to clarify that this is an external dependency, because the only way to resolve a peer dependency warning is to install react from npm—there's no way to notify npm that you resolve the dependency to a browser global. So peer dependencies should be avoided in favor of external declarations. Then Rollup will take care of warning about "unresolved dependencies", even if external declarations can't express a particular version range with which your library is compatible like peer dependencies can.

You can see that Rollup mapped browser globals called "React" and "ReactDOM" to variables called "React" and "ReactDOM". The latter are what you imported by writing import React and import ReactDOM. (The variable names don't have to be the same as the browser globals, but it's common.)

Move svelte into dependencies, as it was accidentally stuck in peerDependencies

To make this “if you install me, you better also install X, Y, and Z!” problem easier, peerDependencies was introduced.

Everyone has an idea about how to make it easier to find needles in the haystack, but no-one bothers to ask what all this hay is doing here in the first place.

Can you re-open this until we fix it?

(Note that you're responsible for handling any race conditions that arise as a result of the component being destroyed before the promise resolves, though assigning state inside a destroyed component is harmless.)

We don't want to rely on there being a single root element - or prevent ourselves from ever implementing named slots without a single root node - and so there's not anything to apply the class to or the transition to.

Also Svelte is so great because developer do not need to worry about class names conflict, except of passing (global) classes to component (sic!).

Just throwing in <div class="{$$props.class || ''} otherChildClass"></div> seems the easiest, and it'll avoid undefined classes. I feel like many aren't noticing the undefined values getting inserted in their classes.

TBH It is a bit disheartening to see this issue closed when all proposed solutions do not sufficiently solve the issue at hand, I really like svelte but if this is how feature requests are handled I am probably not going to use it in the future.
