ANSWER

Answered 2022-Mar-31 at 01:50

operator[] of associative and unordered containers is not specified to be safe from data races if called without synchronization in multiple threads. See [container.requirements.dataraces]/1.

Therefore your code has a data race and consequently undefined behavior. Whether or not a new mutex is created doesn't matter either.

Issue:

Custom functions can only return values (strings, numbers, etc.), not formulas. A "formula" returned by a custom function will just be interpreted as a string starting with =.

Related requests in Issue Tracker:

Workaround 1:

Modify your custom function so that it just returns the url part (i.e. #gid=...) and use that returned value in a =HYPERLINK() formula which is called conventionally by your sheet:

flex items will not stretch and when they unide it moves all my other items in a div

Asked 2022-Feb-08 at 20:21

I am trying to get an input box to stretch the full width of the screen, but due to the items, it is div'd with above it only takes up a small amount and when it unhides it also drags the items above with it. I've tried flex-stretch, align-items: stretch, etc etc etc and nothing seems to work. I even gave it a div by itself and I couldn't get it to work.

If you click the Reply button in the code below it will show you my exact issue:

...

ANSWER

Answered 2022-Feb-08 at 20:21

Hiding the error on your reply button sample... I see the following:

the input and form are all children of an unnamed div with a default width (none specified).

If you set that parent's width to 100%, then your input, which also lacks a width: 100%, will stretch, like so:

You will then need to define what you want to do with your gray chat box but, just keep in mind:

You cannot expect elements to stretch to the full width of anything if they have no specified reason to do so. Check the default width value (auto):

https://developer.mozilla.org/en-US/docs/Web/CSS/width

A child cannot normally grow beyond the limitations of its parent, specially by default, auto width on your input and auto width on its div parent...will never lead to 100% width. You ought to be specific.

EXTRA

To adjust the content of the .user div based on the size of the content, you can try max-content, which would make your examples look like this:

https://blog.logrocket.com/understanding-min-content-max-content-fit-content-css/

Please read this article, it explains in detail max-content, min-content, fit-content, pro's and con's, etc.
