How does the Grammarly chrome extension work - google-chrome-extension

I was wondering how the Grammarly extension is able to underline the words in almost any editor (tinyMCE, CKE etc). I thought they are doing that via CSS but it's not.
I am trying to implement something similar and am very thankful for any advice.

How can I enable spell checker in google colab (colab operates on linux OS)?

Can we enable spell checker for markdown cells in google colab in any way? Please help.
I'm not aware of any way of doing so directly within Google Colaboratory, however a usable workaround might be to install a third party spell-checking browser plug-in such as Grammarly or another similar plug-in that works with your preferred browser, I know this probably wasn't the answer you where looking for, but I'm not aware of any better solutions, I truly apologize! But I hope this was at least somewhat helpful!
Sorry I can't be of more help!
If you're comfortable with PyCharm, you can open your ipynb files in it, and it will highlight any spelling errors.
PyCharm professional edition was used to test this.

How to better expose your chrome extension

I've developed a chrome extension because I needed something that could make pages view things in greyscale.
I tried addons like this but it was completely broken for me.
Anyway, after creating my own, with a lot more than just 'greyscale' functionality I called it something really generic.
So now I'm worried, anyone searching for 'greyscale' or 'webpage photo filter' wont find my extension!
My question is; is there any way to add tags to your extension listing in the store that searches will take into account? Or do you have suggestions on where I should spout keywords in the current description space?
Add keywords into your extension's description, either into sentences, bullet points, or just a simple list at the end.
There are no tags in Chrome Web Store listings. You have to get creative with your text.
A suggestion for your description:
Create your own webpage photo filters!
See things in;
black and white (greyscale)

How to make Google Chrome extension sample work?

Recently I decided to write a very simple Google Chrome extension. All it's going to do is to hide some DOM-elements from the web-page using JavaScript when user presses the extension's button.
Since I knew nothing about Chrome extensions, I started reading tutorials, and I came across this Google's sample: A browser action with no icon that makes the page red
This sample is really close to what I want to make. The problem is that I can't make it work. Whenever I load the extension in Chrome, I can see the button of this extension, but when I press it - nothing happens. Sample doesn't work, probably I should know something I don't know yet.
And before you started asking me:
Yes, I tried restarting the browser;
I use the newest version of Chrome.
Thanks for help.
If you open up the sample zip... find backgrond.js... edit.
Find the line that says:
null, {code:"document.body.style.background='red !important'"});
and remove the "!important". so it should read:
null, {code:"document.body.style.background='red'"});
That is it. just save and reload the extension, should work (unless the page has an !important flag set to the background).
I am afraid I don't know why the "!important" tag doesn't work but I have never been able to get it to work in an extension. Hopefully someone else here will be able to give an explanation and maybe a work around.
I think I can help bring some clarification to the "!important" override attribute causing the extension to break. Though I am not 100% I believe that this attribute is not allowed for issues involving security complications. I have a link to another SO thread that may help clarify this as well.
My CSS is not getting injected through my content script
I'm assuming from reading this article that you must either use the !important override when content scripts specified in the manifest file. Otherwise if the css is being injected !important is not required. Again not 100% on this.

Browser based Code Editor, with real tabbing?

I'm currently using CodeMirror as a browser based code editor, but what really annoys me is its lack of real tabbing. It uses spaces instead of tabs, and I just cant get my code as clean as desktop editor.
Are there any better editors out there? It can be DOM based or Javascript or even browser specific, just as long as it gives me real tabs! :)
PS. I've had a look at Ace, which looks like it should do the job, but I cant seem to get real tabs to work - anyone tried it?
Cheers,
Chris.

Is it possible to provide Code highlighting on sites.google.com websites?

Is it possible to do Code Syntax highlighting on sites.google.com websites like the way we do it on Blogger.com or Wordpress.com?
Unfortunately there is until now no support for syntax highlighting within Google Sites. As a workaround you could use http://tohtml.com/ and enter your code there and copy the colored output (not the HTML) directly into your Google Sites page.
This works perfectly, as long as you don't need to edit large pieces of the code regularly.
I have tried creating a gadget myself with Google Code Prettify, and there were a few issues.
One is that classes aren't supported, so you will have to follow what Stack Overflow is doing to prettify.
http://www.codingthewheel.com/archives/syntax-highlighting-stackoverflow-google-prettify
The other problem I faced was the interaction between the iframe and the parent frame. You will notice that there is a domain permission problem, and so you will be unable to access the parent.document from your iframe.
This should save some people a few hours of hacky testing.
Yes, you can!
Just select the desired text, and go to "Formatting" -> "Code" OR "Block Code"
You can insert gadgets into Google Sites pages. You could create a gadget that did syntax highlighting using any number of open source javascript syntax highlighters.
Not an ideal solution but would get you what you want. Lemme know if you want further pointers.
I've found an alternative way.
If you use IntelliJ, just copy the code from the IntelliJ editor and paste it into your Google site text (not in html mode).
Works out-of-the-box!
