reminds me of Macromedia MXML (used in Flash, Coldfusion and Flex)! https://github.com/apache/royale-asjs/blob/develop/examples/mxroyale/DataGridExample/src/ma

  OpenLaszlo was an eariler, more powerful, more fun, open source alternative to FLEX. It's obsolete now that Flash is dead, but I really got in the "zone" with it.

"Java is a DSL for taking large XML files and converting them to stack traces." -Andrew Back https://www.reddit.com/r/programming/comments/eaqgk/java_is_a_dsl_for_taking_large_xml_files_and/ https://www.reddit.com/r/programming/comments/eaqgk/java_is_... But in all seriousness: OpenLaszlo used XML with embedded JavaScript in a way that let you extend XML by defining your own tags in XML+JavaScript. I've done a lot of work with it, and once you make your peace with XML (which seemed like a prudent thing to do at the time), it's a really productive enjoyable way to program! But that's more thanks to the design of OpenLaszlo itself, rather than XML. https://en.wikipedia.org/wiki/OpenLaszlo https://en.wikipedia.org/wiki/OpenLaszlo OpenLaszlo (which was released in 2001) inspired Adobe Flex (which was released in 2004), but Flex missed the point of several of the most important aspects of OpenLaszlo (first and foremost being cross platform and not locking you into Flash, which was the entire point of Flex, but also the declarative constraints and "Instance First Development" and the "Instance Substitution Principal", as defined by Oliver Steele). https://en.wikipedia.org/wiki/Apache_Flex https://en.wikipedia.org/wiki/Apache_Flex https://web.archive.org/web/20190318072102/https://blog.osteele.com/2004/03/classes-and-prototypes/ https://web.archive.org/web/20190318072102/https://blog.oste... The mantle of constraint based programming (but not Instance First Development) has been recently taken up by "Reactive Programming" craze (which is great, but would be better with a more homoiconic language that supported Instance First Development and the Instance Substitution Principle, which are different but complementary features with a lot of synergy). The term "Reactive Programming" describes a popular old idea: what spreadsheets had been doing for decades. OpenLaszlo and Garnet (a research user interface system written by Brad Myers at CMU in Common Lisp) were exploring applying automatic constraints to user interface programming. Garnet started in the early 1990's. Before that, Ivan Sutherland's Sketchpad explored constraints in 1963, and inspired the Visual Geometry Project in the mid 1980's and The Geometer's Sketchpad in 1995. https://en.wikipedia.org/wiki/Reactive_programming https://en.wikipedia.org/wiki/Reactive_programming http://www.cs.cmu.edu/afs/cs/project/garnet/www/garnet-home.html http://www.cs.cmu.edu/afs/cs/project/garnet/www/garnet-home.... https://en.wikipedia.org/wiki/Sketchpad https://en.wikipedia.org/wiki/Sketchpad http://math.coe.uga.edu/TME/Issues/v10n2/4scher.pdf http://math.coe.uga.edu/TME/Issues/v10n2/4scher.pdf https://en.wikipedia.org/wiki/The_Geometer%27s_Sketchpad https://en.wikipedia.org/wiki/The_Geometer%27s_Sketchpad I've written more about OpenLaszlo and Garnet: What is OpenLaszlo, and what's it good for? https://web.archive.org/web/20160312145555/http://donhopkins.com/drupal/node/124 https://web.archive.org/web/20160312145555/http://donhopkins... >Declarative Programming: Declarative programming is an elegant way of writing code that describes what to do, instead of how to do it. OpenLaszlo supports declarative programming in many ways: using XML to declare JavaScript classes, create object instances, configure them with automatic constraints, and bind them to XML datasets. Declarative programming dovetails and synergizes with other important OpenLaszlo techniques including objects, prototypes, events, constraints, data binding and instance first development.

  I was thinking the same thing. Programmed ColdFusion for over a decade and loved the language, however I moved onto .NET, the PHP and now Rails. ColdFusion was a wonderful language, but the frameworks weren't there and the market share wasn't there either. Ironically enough, one of my clients still uses it for their application and we actually began talks about moving them over to Rails.
