Oh, I just figured out a workaround for my project, in case it helps someone. If you want the source of truth on the prop to come from the child component, then leave it undefined in the parent. Then, you can make the reactive variable have a condition on the presence of that variable. eg: <script> let prop; $: prop && console.log(prop); </script> <Child bind:prop/> Might not work for every use case but maybe that helps someone.

Fixing with containIf we give each article the contain property with a value of content, when new elements are inserted the browser understands it only needs to recalculate the containing element's subtree, and not anything outside it:

(you can get pretty far with <svelte:component> and passing component constructors around and spicing up props along the way)

If you need to pass multiple arguments to an action, combine them into a single object, as in use:longpress={{duration, spiciness}}

Please note that gtk-launch requires the .desktop file to be installed (i.e. located in /usr/share/applications or $HOME/.local/share/applications). So to get around this, we can use a hackish little bash function that temporarily installs the desired .desktop file before launching it. The "correct" way to install a .desktop file is via desktop-file-install but I'm going to ignore that.

Applications can safely autoload constants during boot using a reloader callback: Rails.application.reloader.to_prepare do $PAYMENT_GATEWAY = Rails.env.production? ? RealGateway : MockedGateway end Rails.application.reloader.to_prepare do $PAYMENT_GATEWAY = Rails.env.production? ? RealGateway : MockedGateway end Copy That block runs when the application boots, and every time code is reloaded.

Or use a '?' in place of a space as long as there are no other matching filenames than the one with spaces (since '?' matches any character): rsync -av host:a?long?filename /tmp/

As a work-around I know add a listener to the document-head and move what gets added to the shadow-root.

An #each tag can loop anything with a length property, so: {#each {length: 3} as _, i} <li>{i + 1}</li> {/each} will also work, if you prefer.

One good use for /dev/tty is if you're trying to call an editor in a pipeline (e.g., with xargs). Since the standard input of xargs is some list of files rather than your terminal, just doing, e.g., | xargs emacs will screw up your terminal. Instead you can use | xargs sh -c 'emacs "$@" </dev/tty' emacs to connect the editor to your terminal even though the input of xargs is coming from elsewhere.

One solution is to run this command to reset your keyring password: rm ~/.local/share/keyrings/login.keyring

const allRoles: string[] = Object.values(Role)

If you really want to prevent people from passing in known Cat instances to isDog() you can fake up a lower-bound type parameter constraint like this:

Or, maybe better, interpret the list as a tuple type: const list: ['a','b','c'] = ['a','b','c']; // tuple

You can force the type system to remember each value as a literal string: const list = ['a' as 'a','b' as 'b','c' as 'c']; // infers as ('a'|'b'|'c')[]

In javascript prettier-ignore ignores the next block, so what I did was just make the next few lines a block.

foo({}, **{}) #=> Ruby 2.7: [{}] (You can pass {} by explicitly passing "no" keywords)

Use this to build a ClassAdder component. ClassAdder components are useful for reducing the size of your bundle. If you have tons of simple components that just need to add classes/props or set a context, using ClassAdder components means there's only one "big" Svelte component in your bundle for all of these many tiny components.

This is useful when you need to add classes to a component, since Svelte's "class:" directives don't work on components.

This change should be a workaround for issue #8.

Worth noting that in the case where you're proxying /api/ requests to an external server in nginx you can easily do this in handle today:

I don't know how much workaround is it, but for now I'm using this approach:

If you do need to passthrough your mydomain.com cookies to a thirdparty.com domain, you can technically already do that now by implementing it as an endpoint and calling fetch('/my-endpoint')

on CSR it connects to the svelte-kit endpoint which just use a localhost connection. and to optimize this you can use unix sockets in your endpoints to connect to backend server

Thanks. Worked for me. I needed to move the merged directory into a sub-folder so after following the above steps I simply used git mv source-dir/ dest/new-source-dir

You may want to try putting the one-liner (everything in the single quotes) in an actual script, with a bash shebang line. I think filter-branch is probably trying to run this in sh, not bash.

The super hacky alternative... using an error's stack trace When I got this to work I literally laughed out loud 😂. It might be the most hacky solution to a problem I've found yet

Large regions of memory can be allocated without the need to be contiguous in physical memory – the IOMMU maps contiguous virtual addresses to the underlying fragmented physical addresses. Thus, the use of vectored I/O (scatter-gather lists) can sometimes be avoided.

unbuffer disables the output buffering that occurs when program output is redirected. For example, suppose you are watching the output from a fifo by running it through od and then more.    od -c /tmp/fifo | more You will not see anything until a full page of output has been produced. You can disable this automatic buffering as follows:    unbuffer od -c /tmp/fifo | more

But we can use a two characters delimiter: / (space slash) That pair of characters could only exist at the beginning of a new (absolute) path:

The script support/rsync-no-vanished that will be in the next release.

Another possible solution would be to use a class Common instead of a module. But this is just a workaround.

fill_in('Foo', with: 'bar', fill_options: { clear: :backspace })

It might be possible to fix it in Capybara, but I'm afraid that we'd just add more unexpected, ambiguous behaviour (which key should have been pressed, backspace, space?).

Here's another workaround:

find_field('Prefix').send_keys([:control, "a"], :backspace)

Now, if you also want deskopen to pass through any command-line parameters, you can instead use this slightly-modified version: #!/bin/sh desktop_file=$1 shift `grep '^Exec' "${desktop_file}" | sed 's/^Exec=//' | sed 's/%.//'` "$@" &

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

Note that autosave will only trigger for already-persisted association records if the records themselves have been changed. This is to protect against SystemStackError caused by circular association validations.

You'll still get the correct backtrace, and can use that to view your own sources locally though.

To achieve this, we created a small Compressor which wraps the Uglifier compressor and links the source maps so they are written to disk.

To correct this, you can move these files to some subdirectory of ./app/assets/stylesheets or javascripts; or you can change the manifest.js to be more like how Rails with Sprockets 3 works, linking only the specific application files as top-level targets

Some developers found work arounds by using virtual attributes to # skip validators

I have developed a simple pattern that copies errors from the model or the service into the form object so that the view can still use those errors

Windows and Linux store their time in the BIOS differently, this will cause your clock to be desynchronized when you switch from one OS to the other. The easiest solution for it is to fix it in Linux, forcing it to work the same way as Windows. You can do this through the terminal:

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

on the other hand, documents from different origins can still communicate using window.postMessage(), for example to implement collaborative iframe auto-resizing.

You could use an asymmetrical border to make curves with CSS. border-radius: 50%/100px 100px 0 0;

The solution is min-width: 0; on the flex child Or min-width some actual value. Without this, the flex child containing the other text elements won’t narrow past the “implied width” of those text elements.

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

I want to create a filter for all email sent by me only to me. To accomplish this I send all these "notes" to a permutation that I know no one else uses. E.g. john__doe@gmail.com

How to wrap long word (text without spaces) in html table’s cell? This is very, very easy! We must add only a CSS proprty to table cell “td” tag – “word-break: break-all;” then all column’s widths become as intended. 

use of the border-box property. If you add the following at the top of your CSS file, you should be able to avoid many of the problems inherent in using 100% width on your elements:

Interesting . That feature (<slot slot="..."/>) was only recently added in #4295. It wasn't primarily intended to be used that way, but I guess it's a good workaround for this issue. I'm yet to find caveats to slotting components that way, other than it's inconvenient, as opposed to <Component slot="..."/>.

Related to #1824, can do <svelte:component this={Bar}> <slot></slot> <slot name="header" slot="header"></slot> </svelte:component> <script> import Bar from './Bar.svelte'; </script> as a forwarding workaround

Can't find the Svelte way of doing this, setTimeout helps now, but this is not a good way working with a framework I think.

Or just watch the value with a reactive statement instead of an event handler on the input like: $: inputValue, onInput() This is a good solution and seems to work in all cases.

Note: your arrow must be an HTMLElement (not an SVGElement). To use an SVG arrow, wrap it in a <div> tag with the data-popper-arrow attribute.

If an element is disabled, you will need to use a wrapper element (<span> or <div>) in order for the tippy to work.

I guess it's about "preloading" and not "navigation", if it's the case, then I guess there is still no way to attach to navigation events, and this issue should be kept open.

No JS event is fired, so there currently isn't any clean way to do this that I can see.

delete is a reserved word in JavaScript. To handle DELETE requests, export a function called del instead.

As a workaround for the need of having more than 1 root nodes for the same slot, we can introduce the <svelte:slot> as a wrapper:

Slot element doesn't support bind:this, but it's fallback child does.

If you want a reference to the global object that works in any context, you can read this from a directly-called function. const global = (function() {return this})();. This evaluates to window in the browser, self in a service worker and global in nodejs.

You can either use require to bypass typescript special import.

Hadn't realized I needed to go through PayPal and was stuck using the higher prices on the USPS site.

Currently, I can only do this with some ugly JS, by wrapping the <slot> in a div and then selecting all direct children of that div (div>*). But this fix/solution also makes me face a problem: The <div> partially destroys the layout/design compared to when not using that div wrapper.
