Sorry if the title somewhat ambiguous.
I'm buliding an app that recieve an URL then return the final HTML code (and save it for caching), after Ajax and other js feature executed (something like Phantomjs).
My language can call C++ code, so I think it would be nice if I can buid and use Blink/Webkit libary directly.
The issue is both Blink/Webkit document is too big.
UPDATE 1: Which API (Blink has many APIlayer) or a particular class I need to look at?
Do you know any example or tutorial I should look at?
Or any alternative simpler libary?
Thanks
Finally Chromium project have headless API in development with very good example which can be build using ninja, more information in their project at https://chromium.googlesource.com/chromium/src/+/master/headless/

I've an idea and want to implement it.
But I'm not sure if it's gonna work. So, wanted to get your inputs.
I would like to take screenshots of a url.
Say, when I open a web-site www.espncricinfo.com , I would like to take screenshot of that page and save locally. This saved image can be converted to GIF later on.
Can this be achieved through python ? Any suggestions/inputs to make it ?
Updated
And also is it possible to capture screenshot in headless-browser ?
Any possibilities to launch the browser in headless mode (non-GUI) and then take the screenshot of particular area of web-page ?
To take a screenshot using python:
import pyscreenshot as ImageGrab
im = ImageGrab.grab()
im.save('path/to/image/folder/image_name.png')
im.show()
Yes and no, if you send a request with urllib you will get the HTML in return, which is step one to displaying a webpage. But you have to build that webpage from that with a browser engine, otherwise all you will see is a bunch of text.
There are some python libraries that can do this, such as pywebkitgtk, but those are probably not going to give you the best experience and support.
Another thing you could try is to use crod and firefox/chrome/whatever and then use python to automate the process.
Oh, and by the way, I strongly recommend upgrading to python3
I know it is a bit to late now, but just saw this question and in case anyone else is looking for a mighty tool, to do screenshots and also use headless browsers with python... I just want to recommend to look more deeply into https://www.seleniumhq.org/. There are many tutorials on youtube available. However, this is IMHO the most accurate framework to execute your task, IMHO. To make screenshots, you can then define the screen resolution etc.
I'm admittedly new to Netsuite, so this may be obvious, although I've been unable to find anything specific one way or the other. In fact, I don't even attend any training until next week, but I'm trying to get part of my development environment setup with one of the editors/IDEs I prefer. I know that Netsuite offers an Eclipse plugin, but I'm not an Eclipse fan. I'd prefer to use either WebStorm or TextMate. (I'm on MacOS Sierra)
I tried installing the WebStorm plugin, but it's throwing an exception and is not functional. I submitted a bug on GitHub, but what I'd really like to know is if it's possible for me to write my own script to upload/download files to the cabinet, so I could just roll my own feature in TextMate. Is this possible, and if so, how? (Just a link to the docs is perfectly fine)
In other words, is it possible via their API, to submit changes to a script I've been working on in another editor/IDE? Or interact with our cabinet? (Not sure if I'm using the proper NS verbiage, but hopefully you get my intent) I'm thinking about writing a Python script, that accepts a local script path as a parameter, that will then get submitted to our cabinet. Thanks for the help in advance.
I wrote a plugin for JetBrains IDEs (I use WebStorm specifically though) that mimics NetSuite's Eclipse plugin. Feel free to take a look. It is open source and has ~1500 downloads at the current moment.

If you are the same person that opened this issue (https://github.com/Topher84/NetSuite-Tools-For-WebStorm/issues/7), it has been closed and was due to using an older version of WebStorm.
I don't like eclipse personally, so I just make my scripts in whatever and use Netsuite's script backend to upload the scripts as 'new' when I'm done. If I want to change them, simply use their backend again to 'edit' the script. You'll see a simple editor, where you can change things, or you just copy and paste what you have in there. It's a little more work than something integrated, but it does work..
I am at the beginning of my adventure with Dart, do please be kind :)
I found some answers related to minifying JS files made from Dart (dart2js), but I cannot find any info about minifying Dart code itself.
Is there any plan to do this?
For JS there are some tools i.e. YUI Compressor.
I think Dart need also such application.

Best regards,
Tom
You can use dart2js with the --output-type=dart to output Dart code instead of JavaScript. Coupled with the --minify option you will get a minified dart file.
Looking at the dart tools page: https://www.dartlang.org/docs/dart-up-and-running/contents/ch04-tools-dart2js.html
There are a few things that are perhaps relevant:
--output-type=dart
Output Dart code instead of JavaScript. This option is useful when deploying your app, because it generates a single file
containing everything the app needs.
And tree-shaking removes unused code:
Don’t worry about the size of your app’s included libraries. Thanks to a feature called tree shaking, dart2js omits unused classes, functions, methods, and so on. Just import the libraries you need, and let dart2js get rid of what you don’t need.
Don't know if browser can load snapshot, and never tried. But if so, could fit your needs: https://www.dartlang.org/articles/snapshots/
Hello all CodeIgniter guys :), I'm new to CodeIgniter andIi have now put my project on github. Here is my github page: https://github.com/SimonJ/Hip-hop-project
So I would hear about someone bothered to look through my files and make comments about what I can do better so I can learn something new :)
I have tried to use ocular template system but I get this error:
An Error Was Encounter Unable to load the Requested Class: ocular
Do you know what I'm doing wrong?
This question borders on the edge of belonging on Code Review instead of Stack Overflow, but I'll help you with your templating issue.
Are you running PHP 5 on your server? It looks like Ocular is using "public" and "private" words for functions and variables.
You are running an older version of Codeigniter by the looks of it because I don't see a folder called "core" in your application folder. There's a community version of CI called Reactor here or you can get the standard CI 2.0 from EllisLab here. I would upgrade to one of those, personally I would use Reactor.
Ocular is great but Phil Sturgeon has a lighter template library simply called template you might be interested in looking at as well, here. Like I said in the first paragraph of this answer, go to Code Review if you would like to have your code critiqued and reviewed.
PS. Welcome to Codeigniter, it's an awesome PHP framework.
Is there any browser I could embedd in C++ application on Windows?
I need all features typical browser has (HTTP client, cookies support, DOM style HTML parser, JavaScript engine) except rendering.
Because I don't need rendering capability (and that's rather big part of a browser) I would prefer a browser with non monolithic design so I wouldn't have to include rendering stuff into my project.
It would be nice if it had C++ rather than C API.
I need this embedded browser mainly because I have much trouble finding C++ HTML parser which could handle broken HTML like browsers do.
If you know any, please answer Library Recommendation: C++ HTML Parser SO question or at least vote on it to increase a chance someone will give a good answer.
Sounds like all you need is something like libcurl which is an HTTP library and will let you do GET/POST/etc.
When I think browser I generally think rendering/JavaScript and not HTTP library.
Edit
In that case I'd look at WebKit (which I think has a C++ API) and hope you don't have to pull too much in.
Edit Again
On second thought (since rendering is such a big part of what browsers do), you might be better off using a stand-alone JS engine like SpiderMonkey and a stand-alone XML parser like Xerces-C (plus maybe tidy to make your HTML into XML).
I'm a bit confused by your question regarding embedding a web browser for which you don't need rendering capabilities. A web browser is rendering web pages by definition, unless you just need HTTP and XML with JavaScript capabilities which is a subset of a browser functionalities?
If you need a web browser to embed in your C++ application, I would suggest to consider Qt that comes with the WebKit plugin. It is C++, LGPL and has a very nice IDE (Qt Creator). I tried Qt with Qt Creator on unix (Ubuntu) and it was very impressive. The debugger is a bit light but it is just the first version. The adapter of Qt into visual c++ 2008 is now free.
You might also want to check out Awesomium-- it's free for non-commercial use and has all of the features you're looking for (if you don't need rendering, simply don't use it).
There is a project called CEF = The Chromium Embedded Framework - it is:
a simple framework for
embedding Chromium-based browsers in other applications. It is a
BSD-licensed open source project founded by Marshall Greenblatt in
2008 and based on the Google Chromium project. Unlike the Chromium
project itself, which focuses mainly on Google Chrome application
development, CEF focuses on facilitating embedded browser use cases in
third-party applications.
and yes:
The base CEF framework includes support for the C and C++ programming
languages.
Including javascript support and html parsing makes this non-trivial task - you have to use one of the available browsers.
IE is usable through its COM model - you can create instance of it in your window be it invisible or not and call its javascript/html capabilities.
It has been designed to be used like that since the beginning and certainly it is working fine.
The other options are:
Gecko/Mozilla - a couple of years ago it wasn't usable like this, currently I think it is.
WebKit/V8 - no public API has been released for chrome yet, you could use webkit itself, but it doesn't have javascript engine. Another option is to take a look at the Chrome codebase and see if you could get out of it what you need.
I would probably go for IE, since it is maybe the easiest option and I have already used it. The other options seem to me more like building a browser instead of just using it.
How about Gecko ? You may not need the entire engine but you may find some its components useful like SpiderMonkey which is a JavaScript engine written in C.
I'd recommend picking up Qt for C++ programming. It has a built-in library that embeds Webkit with all the bells'n'whistles, and Qt is a great C++ library in general.
Old question, I know, but take a look on

IActiveScript and family COM interfaces allows script execution (not only JS, any language that registers as script interpeter, for that matter) in-memory.
