Pack opera NEX extension via command line - opera-extension

Can you please assist on way to pack extension using command line and the developer key that we own?
I am afraid I haven't found anything in document.

Try this Gist. It works fine for Chrome extensions and new opera extensions.

http://dev.opera.com/extension-docs/tut_basics.html#step_5__packing_it_all_up provides steps to pack an Opera extension. (in-browser though)

add chromium in Lazarus

want to add chromium web browser in Lazarus, I was doing the following steps, but couldn't run it in Lazarus. it is saying CEF version is not supported. Can you please kindly advise?
I am using Lazarus 1.6 in Win7 64bit
I just downloaded chromium framework from here: https://github.com/dliw/fpCEF3 . As I can see in comments, it is based on CEF 3.2743
Installed cef3.lpk into Lazarus successfully and Chromium tab added
downloaded cef_binary_3.2743.1449.g90ba67d_windows64_minimal.tar.bz2 from http://opensource.spotify.com/cefbuilds/index.html and copied the files from Release folder inside my Lazarus executable file and also copied the Resource folder there.
Also, I tried the last step with cef_binary_3.2743.1449.g90ba67d_windows32_client.tar.bz2 file without any success.
Any help would be appreciated.
Nowadays, GitHub/fpCEF3 says:
update to CEF 3.3029
Keep in mind that this number may change in the future (hopely). And lower it says:
Make sure to use the correct CEF3 version (see the changelog / release tag); other versions (older or newer) may work, but are not recommended
However you are trying version 3.2743, instead of 3.3029 (or whatever it is at the time you are reading this).
Try downloading another version similar to that in GitHub.

Google Chrome file system api: bug in sample code?

I am trying to run this example code:
https://github.com/GoogleChrome/chrome-app-samples/tree/master/filesystem-access
as well as this:
https://github.com/GoogleChrome/chrome-app-samples/tree/master/storage
I am not able to get either of them to run in my browser: Chrome 26.0.1410.65 Mac Lion 10.7.5
(to see it run, download it and click on html page included with each of the examples)
If you can confirm this is a bug in the sample code (it doesn't run in your system as well) please let me know where I should file this bug report. (https://code.google.com/p/chromium/ or https://github.com/GoogleChrome/chrome-app-samples/issues?)
many thanks in advance.
You need to use the Load unpacked extension button found on the chrome://extensions page and then launch the app in order for it to use chrome.* API's.

Syntax Checking for CoffeeScript

I searched google and i didn't found an IDE that would allow Syntax Checking specifically.
Is there a way to check syntax in VS or other tool?
Even though not free, Webstorm comes with good support for Coffeescript out of the box.
By far the IDE I prefer most developing Coffe/Javascript at the moment.
+1 on vim-coffee-script and syntastic.
Have you checked CoffeeScript's wiki? There are few plugins that add syntax checking:
CoffeeScript plugin for sublime
CoffeeScript for Netbeans
You might be interested in using a command line tool like CoffeeLint, which offers optional validation rules. You can add it to your development process writing your own script to watch for changes in files or using tools like Grunt.
See gVim, and install this plugin for syntax checkong, and this one for syntax coloring.
This is a lightweight, scalable, and cheap option.
If you're OK with using Vim, just add the vim-coffee-script and syntastic plugins
If you're into Emacs, there's an Emacs major mode for CoffeeScript.
Here is the blog post announcing its release.

How to add fireshot addons?

I'm trying to install Fireshot addon in opera version 11.62. bt it is not available on opera. Actually fireshot is the extension use for taking screenshot of the current locating site so to make report on the site. so is their any option beside that or can i install Fireshot on it?
Fireshot is a Firefox extension, I don't believe it's available as an Opera extension. You could try installing Lightshot, which sounds like it tries to do something similar (though some of the comments make it sound like it's a bit dodgy), or one of many third-party apps like Screenshot Captor.
Right now it is NOT possible for an Opera extension to do it, though we are working on exposing such functionality in the future through extensions.

What is a xul runner?

The reason I ask is because every e-mail that I get with a link attached I keep getting " Platform Version 1.9.0.4 not compatible with min version>=1.9.0.5 max version<=1.9.0.5.
I don't have a clue how to get rid of xul runner or what I need to do in order for my computer to accept xul or whatever I need to do. Can someone please provide me with step by step (and I mean very explicit step by step) directions on how to do whatever it is I need to do to get this fixed?
XUL is a tool created by Mozilla Corporation (the folks that made Firefox and Thunderbird) to make writing their applications more like writing applications for the web.
With that said, if you're using Firefox to view webmail when you're having this issue or using Thunderbird and having this issue, I would uninstall any plugins you have installed and check it then. If that still doesn't resolve the problem, try uninstalling and reinstalling the application you're using to view the message in.
While this is the wrong place for this question, you could try asking in mozilla support:
