Here's example code which works around the lack of a ??= operator in the wild:

However, this idiom is only an approximation, and introduces subtle bugs when we try to allow false values:

As you've seen, there is no DM system, but you can invite users to chat directly. More generally, consider commenting on the question itself and @-ing the user who made the edit(s). To my understanding, this should work, and it may allow for a quick explanation that doesn't require going in to chat.

Some frameworks call this “template inheritance”. In this example, we might say that the application layout “inherits from” or “extends” the base layout. In Rails, this is known as nested layouts, and it is a bit awkward to use. The standard Rails practice for nested layouts is complicated and involves these considerations

But what if you want to reuse one layout within another?

sums = [0] (1..gains.length).each do |i| sums[i] = sums[i - 1] + gains[i - 1] end could, if scan was introduced, be replaced with: sums = gains.scan_left(0, &:+)

I ran into the same problem and never really found a good answer via the test objects. The only solution I saw was to actually update the session via a controller. I defined a new action in one of my controllers from within test_helper (so the action does not exist when actually runnning the application). I also had to create an entry in routes. Maybe there’s a better way to update routes while testing. So from my integration test I can do the following and verfiy: assert(session[:fake].nil?, “starts empty”) v = ‘Yuck’ get ‘/user_session’, :fake => v assert_equal(v, session[:fake], “value was set”)

I make a file named: app/models/active_storage/attachment.rb. Because it's in your project it takes loading precedence over the Gem version. Then inside we load the Gem version, and then monkeypatch it using class_eval: active_storage_gem_path = Gem::Specification.find_by_name('activestorage').gem_dir require "#{active_storage_gem_path}/app/models/active_storage/attachment" ActiveStorage::Attachment.class_eval do acts_as_taggable on: :tags end The slightly nasty part is locating the original file, since we can't find it normally because our new file takes precedence. This is not necessary in production, so you could put a if Rails.env.production? around it if you like I think.

As far as I see the current version of arel gem is not support FROM keyword for the sql query. You can generate a query using the SET, and WHERE keywords only,

The thing is Chrome doesn't provide details about such resources.

So far for the obligatory warning. I get the point, I even agree with the argument, but I still want to send a POST request. Maybe you are testing an API without a user interface or you are writing router tests? Is it really impossible to simulate a POST request with Capybara? Nah, of course not!

Good commit hygiene is considered a best practice. GitLab should encourage and enable these kinds of best practices. This feature currently creates a problem and requires workarounds that remove information, or significant manual work.

Can you refactor your code so that instead of returning from within the transaction block you set a variable and then return outside of the block?

Note that one extra type that is accepted by convention is the Boolean type, which represents both the TrueClass and FalseClass types.

This is great because it works in Terminal, iTerm2, Chrome, Sublime & Outlook. The alternative (Karabina) is less good because that maps "Home" to Command+LeftArrow, which actually switches windows in Terminal.

There are ways to create aspect-ratio sized boxes in HTML/CSS today. None of the options are particularly elegant because they rely on the “hack” of setting a zero height and pushing the boxes height with padding. Wouldn’t it be nicer to have a platform feature to help us here?

Yep, we experimented with this, but what we found is that you loose most of Svelte's niceness like slots, and instead you'll pass around deeply nested objects.

while with server/externalFetch there is no direct way to pass cookie headers from the original request to the external one

Right now I am working around this issue by having an internal [...api].js, then call fetch for that endpoint (which automatically passes on cookies) and from there hit the actual external endpoint. It works, there is no risk of leaking anything, but imo shouldn't be necessary.

I am currently circumventing this issue by using getSession to have access to the cookies/headers in the load method

With JavaScript, you can actually calculate the width of the scrollbar and whether it’s visible by comparing two properties—window.innerWidth and document.body.clientWidth. If these are equal, the scrollbar isn’t visible. If these are different, we can subtract the body width from the window width to get the width of the scrollbar:const scrollbarWidth = window.innerWidth - document.body.clientWidthWe’ll want to perform this both on page load and on resize, in case someone resizes the window vertically and changes the overflow. Then, once we have the scrollbar width, we can assign it as a CSS variable:document.body.setProperty("--scrollbarWidth", `${scrollbarWidth}px`)

I think that it's nonsense not to have a method that just gives -1 or +1. Even BASIC has such a function SGN(n). Why should we have to deal with Strings when it's numbers we want to work with. But's that's just MHO.

First, no joypad support. It's not a big deal because you can still use big picture emulation or joy2key

Too new to comment on the specific answer

After some searching i found a stack overflow problem that didn't fix my issue but anyhow… I simply used a little ruby and the capybara library to find the field myself with some case insensitive regex and the ruby detect method

If I were to sum up why in one sentence, it's because I don't miss useEffect. I understand why it exists, I understand the approach React takes, and there are benefits of its approach. But writing complex React components feels more like admin; a constant worry that I'll miss a dependency in my useEffect call and end up crashing my browser session. With Svelte I don't have that lingering feeling, and that's what I've come to enjoy.

One gripe I've had with this approach is that you lose the visual cues that you're passing children into the Box component; they now aren't nested within the Box when you render them like we're used to in HTML; it's now up to you to read the props and spot which ones are being used to provide children.

Here's where I start to have a preference for Svelte; the two are very similar but once I got used to Svelte I found that React felt like jumping through hoops. You can't create a worker instance, it has to go in a useRef, and then you can't easily pull code out into a function without then requiring useCallback so it can be a safe dependency on useEffect. With Svelte I write code that's closer to "plain" JavaScript, whereas in React more of my code is wrapped in a React primitive.

because React components are re-executed every time the component re-renders, you can easily end up with thousands of workers being created! It's essential to use useRef to avoid this problem by maintaining a reference to the worker that you've created.

If you really want this, I suggest you write a little function that extracts the executable name from the .desktop file and runs it. Add these lines to your shell's initialization file (e.g. ~/.bashrc): runDesktop () { eval "$(awk -F= '$1=="Exec"{$1=""; print}' "$1")" } Then, you can run your .desktop file with runDesktop ~/Desktop/slack.desktop

A solution is almost indicated in the question: hinder xdg-open from choosing exo-open. A brute-force approach is to copy /usr/bin/xdg-open to /usr/local/bin (/usr/local/bin is earlier in PATH unless PATH has been modified) and to patch it to use open_generic instead of exo_open (unlike the XFCE4-specific exo-open, open_generic does honor xdg mime types)

Works also on Linux if you install Steam for Windows on Wine.

I've been able to find three alternatives ahead of the bugfix

There is (currently) no CSS selector for detecting directly whether an input control has a nonempty value, so we need to do it indirectly, as described above.

Dave Rupert has a good solution that uses an input's invalid event. Instead of using the :invalid pseudo selector, he adds a CSS class to the input when it becomes invalid. We will extend this approach by removing the CSS class when the element becomes valid again.

Validating forms has notoriously been a painful development experience. Implementing client side validation in a user friendly, developer friendly, and accessible way is hard. Before HTML5 there was no means of implementing validation natively; therefore, developers have resorted to a variety of JavaScript based solutions.

You need to create a copy of the method or the class of your callable task in order to fix this and have two identical steps.

For now I've worked around this by putting all the key-value pairs into an array before passing them into the interaction, then re-building the hash inside the interaction. It works, but it requires some extra code

You can use it by allowing a hash with arbitrary keys, but that loses type-safety one that object.

Thanks, I'll continue leaning on the array workaround for my use case then.

I had to use something like this: occupancy.errors.messages.each do |column, messages| messages.each { |m| errors.add(column, m) } end

So how are we going to create a model that doesn’t have a database table behind it? There are several potential solutions including various plugins but we’re going to use the method described in an entry on the Code Tunes blog. This shows a techinque that involves overriding a couple of methods in an ActiveRecord model and then manually defining the columns in the model file rather than in the database table. In our Recommendation model we’ll add in the two overridden methods and then use the column class method to define the columns in a similar way to how they’re defined in a migration file.

With the introduction of CPUs which ran faster than the original 4.77 MHz Intel 8088 used in the IBM Personal Computer, programs which relied on the CPU's frequency for timing were executing faster than intended. Games in particular were often rendered unplayable. To provide some compatibility, the "turbo" button was added. Engaging turbo mode slows the system down to a state compatible with original 8086/8088 chips.

There is nothing wrong with accepts_nested_attributes_for. This is what you should use in your typical case. My post describes a non-typical case. ContactListForm is not an ActiveRecord object, it is an object that includes ActiveModel::Model, which does not support accepts_nested_attributes_for.

A.joins(:b) .where( A.arel_table[:something_a].eq('xxx').or(B.arel_table[:something_b].eq('yyy')) )

If you need your grid to utilize a gap between columns / rows, you won't be able to use the gap property when using this method. You'd instead need to resort to some negative margin manipulation to handle the extra gap space.

I hope we see new CSS capabilities arise that allow this sort of effect without the need for trickery.

Since CSS doesn’t (yet) offer a way to style grid cells, areas, or tracks directly, we have to stretch elements over the parts we want to style independently from the elements that contain content.

proposes adding a grid-cell pseudo so you can add (responsive) decorative elements to grids without having to add empty elements to your page.

Change any of the <option> by double clicking on the number.

It won't work if $HOME is not under /home. Really. Not even if you softlink. You need a bind mount

Why did I put the kdb in the snap file system? Because the app is sandboxed, so I had no choice.

Yarn only runs the postinstall hook after yarn and yarn add, but not after yarn remove. The postinstall-postinstall package is used to make sure your postinstall hook gets executed even after a yarn remove.

It seems being able to bind:this={slotEl} directly on a slot element is a popular request. I'll add my +1 as adding div wrappers just to get dom references gets old really fast.

Not being cancelable makes validating dialog content impossible - eg a login dialog or anything that takes user input. Of course, it's easy enough to get around - but I think this should be a requirement of a dialog.

# Run once, hold otherwise if [ -f "already_ran" ]; then echo "Already ran the Entrypoint once. Holding indefinitely for debugging." cat fi touch already_ran

Edit this file (corresponding to your stopped container): vi /var/lib/docker/containers/923...4f6/config.json Change the "Path" parameter to point at your new command, e.g. /bin/bash. You may also set the "Args" parameter to pass arguments to the command. Restart the docker service (note this will stop all running containers):

Thanks so much for the reply! Due to space limitations for comments, I have appended my reply to my original question. Thanks again! (P.S. I can't up-vote your reply until my rep hits 15... Sorry about that.)

If this is getting implemented, I think I'll love to see both implemented. I can see a lot of use cases where I would like to encapsulate the component with additional wrappers and in another scenarios I would like to just use the component. Now i work around this using empty div but then at times it breaks the structure because of the div element and I'll have to add more class utilities to make it work. This will be a great addition for Svelte.

I also tried to use <!-- svelte-ignore unused-export-let --> before the script tag but still no chance.

You can only adopt a workaround, which can be one of

I use a mutator and use it's changeValue function to 'change' the value of the relevant field (I supply the same value). This in turn notifies all relevant parties of the change to the form's state, and a validation is triggered.

Use the same value that was submitted, which ensures that a 'change' is triggered even though the value itself doesn't change. Therefore, the same value gets validated again.

  mutateValue([name], state, { changeValue }) {
    // change the value to the same value, thus
    // triggering a revalidation of the same value
    changeValue(state, name, value => value);
  }

I have a feature spec to test the Javascript behavior of the blur event, sadly Capybara's native DSL doesn't seem to support it yet.

I discovered that a solution can be hacked using an {#if}, but a proper one would be nice:

Offsetting the rules of a logic-less template requires a lot of helper methods.

I had this problem and figured out how to make something like this work with the compiler quirks.

Here's a proxy store I wrote to derive the value of a store nested within other stores, it plays nice with typescript and can go infinitely deep

This reactive statement is just used to have the store automatically subscribed and unsubscribed.

the code is a bit verbose/convoluted

Using another reactive statement with $effect we have Svelte automatically handle subscribing and unsubscribing to the store

React hook for creating a value exactly once. useMemo doesn't give this guarantee unfortunately - https://reactjs.org/docs/hooks-faq.html#how-to-create-expensive-objects-lazily

I guess we could always add a bunch of adapter code to watch the flag and trigger a callback when it becomes true or false...

Modules using code that doesn’t exist in browsers such as process.env.NODE_ENV and forcing you to convert or polyfill it.

The problem with working around the current limitations of Svelte style (:global, svelte:head, external styles or various wild card selectors) is that the API is uglier, bigger, harder to explain AND it loses one of the best features of Svelte IMO - contextual style encapsulation. I can understand that CSS classes are a bit uncontrollable, but this type of blocking will just push developers to work around it and create worse solutions.

Would style .classInChild from your parent. The only drawback is that you might need an extra wrapping element.

For my simple tooltip example, I could create a TooltipHitbox component with a <slot/> inside a <div use:myTooltip={tooltipProp}> and then wrap MatButton instances with that component.

Also, I'm starting to wonder if maybe it's okay to have multiple spreads? If the alternative to <Foo {...a} {...b} {...c} d={42}> is that people will write <Foo {...Object.assign({}, a, b, c)} d={42}> anyway, then do we gain anything with the constraint?

{#each section as {tag, is_self_closing, props, content}} {#if is_self_closing} <{tag} {...props} /> {:else} <{tag} {...props}>{content}</{tag}> {/if}

Even without going to that extreme, the constraint of having a single <style> can easily force component authors to resort to the kinds of classes-as-namespaces hacks that scoped styles are supposed to obviate.

:global just feels like a hack for a feature that should already be there.

Force everything to the git root per NPM lameness

For a non-monorepo package you can simply point directly to the Github repo. This case is similar, but you want to scope it just to a single package within the repo. For those that make monorepos they don't necessarily need this feature. It's for those that use projects that use monorepos. Telling them to not organize their projects into monorepos doesn't help people who make use of these projects.

npm's inability to handle monorepos then i'd have designed my repos accordingly

I could add .json on the end, but that would mean hacking away at angularjs, which is doing the right thing. I would rather find a good solution and hack away at rails, which is doing the wrong thing :)

In that case I would suggest to use .xml or .json format to eliminate accept header parsing issue.

Safari sends following order application/xml (q is 1) application/xhtml+xml (q is 1) image/png (q is 1) text/html (q is 0.9) text/plain (q is 0.8) \*/\* (q is 0.5) So you visit www.myappp.com in safari and if the app supports .xml then Rails should render .xml file. This is not what user wants to see. User wants to see .html page not .xml page.

Creating and calling a default proc is a waste of time, and Cramming everything into one line using tortured constructs doesn't make the code more efficient--it just makes the code harder to understand.

This is it. I'm done with Page Translator, but you don't have to be. Fork the repo. Distribute the code yourself. This is now a cat-and-mouse game with Mozilla. Users will have to jump from one extension to another until language translation is a standard feature or the extension policy changes.

None of these methods are ideal and honestly, I'd only blame Mozilla for this. They dismiss all our efforts as incorrect but refuse to provide the correct solution.

ssh doesn't let you specify a command precisely, as you have done, as a series of arguments to be passed to execvp on the remote host. Instead it concatenates all the arguments into a string and runs them through a remote shell. This stands out as a major design flaw in ssh in my opinion... it's a well-behaved unix tool in most ways, but when it comes time to specify a command it chose to use a single monolithic string instead of an argv, like it was designed for MSDOS or something!

I think, it's better to replace \n symbol with some other symbol, and then work as usual:

This problem can also come up when you use npm link or an equivalent. In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming myapp and mylib are sibling folders, one possible fix is to run npm link ../myapp/node_modules/react from mylib. This should make the library use the application’s React copy.

This does not set the native input element to indeterminate due to inconsistent behavior across browsers. However, we set a data-indeterminate attribute on the input.

// This is not really a mock, but jest prevents out of scope // variables unless prefixed with "mock".
