@darnocian, according to the documents, since custom function for the template must be defined as static class methods, how do I access contextual data in those utility methods? I can see you can use `class var` to pass contextual data to the utility class before calling `Template.Eval`, but in case of multi-threaded template rendering, it seems that locking is unnecessarily needed. But at least it's workable? I'll try but you might have a better answer? Thanks. It'll be great if ITemplateFunctions.AddFunctions supports non-class methods, so that in the methods the object's fields are accessible.

Hello, I don't remember since exactly when, but about a few weeks ago my XE4 IDE complains about "duplicates not allowed" when opening a project. Here is the call stack caught by madExcept. It seems has something to do with the Interbase DBX driver which I don't use at all and I can disable it, if anybody kindly tells me how. Any hints would be appreciated!

For my new project I need a template engine for generating web pages, while I have concluded which suited my needs the best and I'm quite confident about my conclusion, your opinions and comments might help me to make my final decision. Since mORMot is my go-to framework for server-side web development, the first candidate to consider is obviously DMustache, which is a fast Delphi/FPC implementation of the popular logic-less Mustache template engine. Actually I've used it in several of my projects and it's great. But sometimes I need more features, but as you know, logic-less means no "if", "while", and so on. And fortunately I found Sempare Template Engine, which is the only feature-rich template engine for Delphi ( Yes, I meant it, because we all know Delphi was/is mostly focused on GUI development but not web development...) Pros === - Very very feature-rich, "if", "for and while loop", "include", "JSON", "custom methods", and so on. Basically, the feature set it's very close to template engines you can find in web-focused languages such as Java. No other Delphi template engine is even comparable (sorry, I love DMustache, but I also need "if" and "while"...). - Very well designed! You can tell by just looking at the unit namespaces and the source! - Documented, and with examples. - Well-tested (with DUnitX tests) Cons: While It's also open source, but for commercial uses you need to buy a license key with a very reasonable price. There are other template engines too, but IMHO, only DMustache and Sempare Template are serious, so I won't list them here... Your comments are welcomed!

Well done! Is it possible to extract datetime from a uuid?

Why I haven't heard about this before? It seems to be the only one that's cross-platform. I watched the intro video and it sounds very good. How does it compare to madExcept?

I'm so disappointed to hear that!

I'm so disappointed to hear that!

By now do you mean Delphi 11 or 12? I'm using 11 and the LSP server is quite unstable and as a consequence code completion, code navigation, and everything that relies on the LSP server becomes unusable at all... That being said, I don't want new features but stability enhancements to existing critical features.

What a great news for the new year!

"not yet available", does it mean there will be a TLS layer sometime in the future ? For http client it's sensible to just use clients in mORMot, but there are cases where you need to use Indy :)

Wow! You never cease to amaze us ab! Does it mean Indy can use it instead of OpenSSL for supporting the latest TLS/SSL standards?

In case anyone is interested, and better, want to contribute, I've upgraded THunSpell which was originally written by Stefan Ascher to support Unicode Delphi and created a github repository. Attached Demo screenshot.

I asked a similar question on the Delphi facebook group some time ago, and the feedback were all positive. I think it only make sense to use the Chilkat DLL if you really can't find an alternative with source code.

@Alexander Sviridenkov This is very cool and can be very useful! While I have a faith in your libraries, the only thing I'm concerning about is the performance. Is it based on the good old and fast RTTI (System.TypInfo.pas) or the new but slow extended RTTI (System.Rtti.pas)?

SQL is the most proven and widely-used DSL on earth, and it's the best option. Forget about those clunky and strange syntax of the so-called full-fledged ORM's.

What happened to them? Yes, it seems that the website is no longer available...

Wow, well done!

After working on 11.3 for months, my conclusion is that the LSP-based code completion and code navigation is much much unstable than the old non-LSP versions. I always have to kill the LSP server to get it back to normal...

I created a simple demo project for mORMot web framework and Sempare Template Engine, both are the most powerful ones in their own catalogs, thus worth knowing how they can work together.

Graphics32 + Angus's GR32_lines and GR32_text can be firm foundation for graphical apps. And no one mentioned https://github.com/fatihtsp/Blen2d4Delphi ?

I need advise on solving the IDE help system not working issue, it's XE4 on Windows 7. I don't know since when it stopped working, but the error is as following: RAD Studio's help namespace is not defined. Please reinstall RAD Studio's documentation. class not registered, ClassID: {314111F0-A502-11D2-BBCA-00C04F8EC294} So I found the instruction from embt: https://support.embarcadero.com/article/43035 The help installer almost worked until I got the following error: H2Reg.exe ** Error ** MS Help 2.x runtime files are not installed on this PC. Installation/registration of Help files cannot proceed. According to Google and a MS forum post, I need Visual Studio 2008 SDK which still has a download on cnet.com, so I got it. But the installation cannot proceed since I don't have Visual Studio 2008 installed, so I stuck. I don't want to re-install the full XE4 because I've got so much IDE plugins and custom settings. Any advise? Thanks.

Thanks for the info, tried both h2reg and h2viewer, both give me the following error: MS Help 2.x runtime files are not installed on this PC. I wish Delphi kept using the good old CHM or .hlp help file formats...

See attached, I think I have all the VC 2008, 2010, 2012, 2013 and 2017 redistributables...

The Cromis IPC framework is very well designed, it has a background thread running for receiving the messages, and only call your event handler when there is a message. I have several successful use cases with it.

I've been wanting such feature from the IDE for so many years already! And now you've done it! Well done @dummzeuch
