We are pleased to introduce the Stack Overflow and Stack Exchange liquid tags. These embeds, assembled in native HTML within posts (as opposed to iframe, JavaScript, etc.) are designed for telling better tales about the code we write.
Stack Overflow questions and answers are a big part of our coding lives and the richest source of software knowledge in the known universe. We hope that this integration will help elevate great answers for further discussion and inject a bit more community into the Stack Overflow flow.
Use these embeds for any reason, be it a meta conversation about an answer, boosting a question to your followers on DEV, organizing a roundup of great answers, or simply additional reading to include in any DEV post.
To make an embed, pluck the ID from the Stack Overflow URL and add it to your posts like so:
{% stackoverflow 57259126 %}
This will create an embed like this:
As far as I know, reference/pointer aliasing can hinder the compiler's ability to generate optimized code, since they must ensure the generated binary behaves correctly in the case where the two references/pointers indeed alias. For instance, in the following C code,
void adds(int *a, int *b) {
*a += *b;Here's another question:
I was practicing some JavaScript when one of my friends came across this JavaScript code:
document.write(('b' + 'a' + + 'a' + 'a').toLowerCase());The above code answers "banana"!
Can anyone explain why?
Here is an answer:
In a one-liner:
sum(x == y for x, y in zip(a, b))
And here is a DIY Stack Exchange community question:

I have a set of tools I use on my desk that are bulky and never seem to store well. These include my wirecutters, pliers, ruler, and snips.
At the moment, the best way I've found to store them is in this pencil holder with half the leg inside and…
Thank you to to @antogarand for first suggesting this feature, and thanks to the folks from Stack Overflow who dipped into the issue thread to offer guidance and encourage us to ship this!
Suggestion: Stack Overflow liquid tag
#1419
Is your feature request related to a problem? Please describe.
I just noticed we don't have a liquid tag for stack overflow questions or answers while trying to embed one of these on my post.
It could be a nice addition considering the developer-focused website.
Describe the solution you'd like
Using {{ SO stackoverflow-url }} or a similar syntax to embed a stackoverflow question or answer into the post.
Additional context
One thing to consider while doing this feature is all of the different subdomains on the stackexchange website.
Here is a website listing most of the different domains / communities there are:
https://stackexchange.com/sites
From a quick glance, it seems the following domains are valid:
- https://stackoverflow.com
- https://stackexchange.com
- https://superuser.com
- https://mathoverflow.net
- https://*.stackexchange.com
- https://es.stackoverflow.com
The last two are subdomains: Any stackexchange subdomain, and apparently few language-specific stackoverflow subdomains.
The variety of domains means we can't only use {{ so [post-id] }} as syntax, as we won't know where to fetch the ID from.
Perhaps we could use a simplified syntax of {{ so [id] [Opt: Q or A] [Opt: Domain] }}
Where the default mode would be Question and Stackoverflow.com, but they can be overwritten by the user-specified values.
Here are few sample valid URL formats for:
Questions https://math.stackexchange.com/q/12186 https://math.stackexchange.com/questions/12186 https://math.stackexchange.com/questions/12186/arc-length-of-b%c3%a9zier-curves https://math.stackexchange.com/q/12186/anything
Answers https://math.stackexchange.com/a/64769 https://math.stackexchange.com/a/64769/anything
