Hi,

I am the lead developer for the project PHP Nightrain. Currently, it is coded in Python and using WxPython to create the GUI, etc? For the most part it does what it was designed to do.

But it is not quite where I would like it to be. Currently, it is using the WebView control from WxPython. So, on Windows the software uses IE, on OS X it uses Safari and on Linux it needs the libwebkit-dev to work. The WebKitCtrl is only for OS X :(

I want to accomplish the following:

1. Remove WxWebview or make it optional.
2. Embed WebKit in my Python application. So, on Windows, Linux and Mac it will use webkit by default.
3. Everything has to be packaged in a single executable. I don?t want my users to manually install libwebkit-dev, etc? Not really sure how to accomplish that with pyinstaller.

Can you give me a top level idea on what I will need to do to make it possible? I guess the main question I am asking is?. how do I take webkit source and bind it in my Python application? I am assuming I will have to learn C/C++? but I?m not sure where to go after learning C/C++?

Qt5 bindings for Python was excellent. But their confusing licensing terms is making me skeptical to use their solution.

PHP Nightrain is licensed under MIT and PySide is licensed under LGPL but the actual Qt5 libraries are licensed under GPL, LGPL and Commercial. Can my project use PySide without any restriction? I want my users to download PHP Nightrain binaries and use it for whatever they want (open source, commercial, whatever). So, I am not sure whether PySide LGPL license and Qt5 Licenses will make an issue out of it :/?

As far as I've come to understand you're free to distribute PySide apps so long as they stay open source. I also found it very confusing. With that in mind packaging it into a single executable may break that license. I've yet to see a reliable method of packaging Python 3 into a single file. Python 2 can do it though I hear.

I don't know if this is what you're looking for, but there's Python bindings for GTK's Webkit port. GTK works across most platforms.

 

i did use this on my linux distros but there's no precompiled "WebKitGtk" on the Windows platform. And WebKitGtk does not provide any instructions for compiling it to Windows either. It's something along the line where you have to compile Webkit on windows first and then the WebKitGtk bindings... and then you can use PyWebkitGTK. There is a .NET Webkit control though... so, I might have to do something with IronPython -_-

It's possible to build the source for Windows (cross compilation or Mingw/Cygwin), but you'd need Mingw and associated tools. Failing that, there are some precompiled binaries around. I can't attest to how well they work or how up to date they are, but it's an option. Ideally, you'd want to build it yourself to get the latest and greatest, as well as compiler optimisations (-march=) suitable for the target machine(s). I understand that not everyone is versed in those disciplines though.

    • LibreOffice 25.2.4

      By Copernic · Posted

      LibreOffice 25.2.4 by Razvan Serea LibreOffice is the free power-packed Open Source personal productivity suite for Windows, Macintosh and Linux, that gives you six feature-rich applications for all your document production and data processing needs: Writer, Calc, Impress, Draw, Math and Base. Support and documentation is free from our large, dedicated community of users, contributors and developers. You, too, can also get involved! Choosing Between LibreOffice Still and LibreOffice Fresh: LibreOffice Still is a good choice if you value stability, a longer support cycle, and a more conservative approach to software updates. It's suitable for businesses and organizations where reliability and compatibility are crucial. LibreOffice Fresh is ideal if you're an enthusiast or an early adopter who wants to stay on the cutting edge of LibreOffice development and is willing to accept more frequent updates and occasional minor issues. Features: Writer is the word processor inside LibreOffice. Use it for everything, from dashing off a quick letter to producing an entire book with tables of contents, embedded illustrations, bibliographies and diagrams. The while-you-type auto-completion, auto-formatting and automatic spelling checking make difficult tasks easy (but are easy to disable if you prefer). Writer is powerful enough to tackle desktop publishing tasks such as creating multi-column newsletters and brochures. The only limit is your imagination. Calc tames your numbers and helps with difficult decisions when you're weighing the alternatives. Analyze your data with Calc and then use it to present your final output. Charts and analysis tools help bring transparency to your conclusions. A fully-integrated help system makes easier work of entering complex formulas. Add data from external databases such as SQL or Oracle, then sort and filter them to produce statistical analyses. Use the graphing functions to display large number of 2D and 3D graphics from 13 categories, including line, area, bar, pie, X-Y, and net - with the dozens of variations available, you're sure to find one that suits your project. Impress is the fastest and easiest way to create effective multimedia presentations. Stunning animation and sensational special effects help you convince your audience. Create presentations that look even more professional than the standard presentations you commonly see at work. Get your collegues' and bosses' attention by creating something a little bit different. Draw lets you build diagrams and sketches from scratch. A picture is worth a thousand words, so why not try something simple with box and line diagrams? Or else go further and easily build dynamic 3D illustrations and special effects. It's as simple or as powerful as you want it to be. Base is the database front-end of the LibreOffice suite. With Base, you can seamlessly integrate into your existing database structures. Based on imported and linked tables and queries from MySQL, PostgreSQL or Microsoft Access and many other data sources, you can build powerful databases containing forms, reports, views and queries. Full integration is possible with the in-built HSQL database. Math is a simple equation editor that lets you lay-out and display your mathematical, chemical, electrical or scientific equations quickly in standard written notation. Even the most-complex calculations can be understandable when displayed correctly. E=mc2. LibreOffice also comes configured with a PDF file creator, meaning you can distribute documents that you're sure can be opened and read by users of almost any computing device or operating system.

    • Here's why it makes sense to name it iOS 26 and why it doesn't

      I'm not sure why, but for some reason I think that if they are deciding to use the year for the version history they should use the whole year (i.e. iOS 2026).
    • Here's why it makes sense to name it iOS 26 and why it doesn't

      By Aditya Tiwari · Posted

      Here's why it makes sense to name it iOS 26 and why it doesn't by Aditya Tiwari It has been almost 18 years since Apple launched the first version of its popular mobile operating system alongside the original iPhone. Recent reports and rumors circulating on the web suggest that the company is all set to unveil a major overhaul for iOS 19 at this year's WWDC keynote. There is something that baffled many when they found that the Cupertino giant is reportedly planning to rename iOS 19 to iOS 26. Yes, a company like Apple skipping eight versions for iOS is enough to leave users with a "why?" expression on their face. However, even if Apple pulls it off, there are two sides to the coin. Why it makes sense to call it iOS 26 There are several reasons why calling it iOS 26 instead of iOS 19 isn't as weird as it sounds. To begin with, it's something that has been done in the past. Samsung is a well-known example when we think about renaming device lineups and skipping version numbers. Samsung launched the Galaxy S20 series in 2020. But what was its predecessor? Galaxy S19? No, it was the Galaxy S10. The South Korean giant renamed its device lineup and aligned it with the year of launch, jumping ten versions in the process. So, someone viewing a Galaxy S23 can easily determine that the device was launched in 2023. It also gives them a feeling that they are using the 'latest and greatest' product. On the flip side, a device from the previous year may feel outdated, potentially motivating them to upgrade. Skipping version numbers isn't fun and games for everyone. Microsoft became the butt of jokes when it skipped Windows 9 and announced that Windows 8.1 will be upgraded to Windows 10 (that too in 2015). Windows 10 was thought to be "the last version of Windows", but things turned out differently. Apple's case would be a bit different, where the iOS version number is one year ahead. So, iOS 26 will release in 2025, iOS 27 in 2026, and so on. This approach is similar to how game companies like Electronic Arts name their gaming titles. Although it may seem off track, the naming scheme aligns with Apple's development schedule. The company typically announces new iOS versions at WWDC in June and rolls them out to the public in the fall season. After that, it continues to push incremental updates through the following year. In other words, a particular iOS version lives on your iPhone for a quarter of the launch year and about nine to ten months in the following year. Meanwhile, Samsung releases new Galaxy S devices at the start of the year, so it makes more sense to align their name with the current year. Not just iOS 26, reports said that Apple will streamline its confusing software naming system by renaming almost all of its operating systems to a single version. So, there will be iPadOS 26, macOS 26, tvOS 26, and watchOS 26 instead of iPadOS 19, macOS 16, tvOS 12, and so on. While the big move will make things easier for users, it will also highlight the work Apple has been doing to unify its software experience across devices. iOS and iPadOS have been related to each other from the beginning, but macOS gained ARM support in 2020 and began incorporating iOS-like UI elements. Apple has already developed a suite of Continuity features that enable different Apple devices to work together. macOS 14 Sonoma further bridged the gap between iPhone and Mac in 2023 with a revamped widgets picker UI, which allows access to and syncing with widgets stored on your iPhone. New widgets introduced in macOS 14 are interactive, similar to those on iPhone. They let you do stuff like checking off reminders, playing or pausing media, accessing smart home controls, and more. Apple's iOS 26/iOS 19 would be the second major naming shake-up in the history of iOS. The first one was when Apple renamed the operating system from iPhone OS to iOS in June 2010. iOS 26 is expected to be the biggest update in years, reportedly featuring a 'dramatic' glass-like UI overhaul, a revamped Camera app, live translation for AirPods, a new gaming app, and a new set of accessibility features. The glass-like design, first introduced on Apple's Vision Pro headset, is expected to make its way to tvOS and watchOS. Why doesn't it make sense to call it iOS 26 It already feels a bit awkward when you realize that the iPhone 16 runs iOS 18, for whatever reason, when the first iterations of both iPhone and iOS arrived in the same year. Adding eight more digits to the iOS version number will make it sound even weirder. The 19th generation of iPhone's operating system will be called iOS 26. Imagine buying an iPhone 17 later this year, and it runs iOS 26 out of the box. However, there are a couple of things Apple can do to tone down the awkwardness. Perhaps Apple can rename the iPhone series and start calling it iPhone 26 to match its software counterpart. A far-fetched and even more unlikely option is to drop version numbers from the iPhone's name entirely. Apple is already doing it for its tablets (iPad, iPad Pro, and iPad Air) and its Mac computers. Therefore, it won't be an issue once the users absorb the initial shock of the announcement. But we can't ignore that not having a version number tied to a product has its downsides. These are all speculations anyway. Whatever happens, Apple fans will get over it and learn to live with it, like they are living with the hopes of an upgraded Siri and AirPower to charge their Apple devices together.
