Miva (Htmlscript)
Miva, formerly Htmlscript, is a web applications development system that provides support of new HTML-like tags that allow developers to create complex applications with little to no programming experience. The Server based program, called the Miva Empresa Engine, functions as a pre-processor which reads the Miva tags and markup language syntax and then outputs the HTML to the browser.

In addition to all the scripting features of Htmlscript 2.x and lower, Miva, the 3.21 release, comes with some major enhancements and represents a very substantial upgrade of Htmlscript. Features of the new Miva include:

  • Completely redesigned architecture for faster performance
  • xBase compatible integrated multi-user database
  • Integrated commerce processing system
  • Advanced error reporting
  • Built-in and User Defined Functions
  • SGML/XML compliant syntax
  • Cached configuration information
  • Backwards compatibility with Htmlscript 2.x

Miva also comes bundled with many ready to run sample applications. For more detailed information, site administrators should review the Administrator's Manual. Additional details about Miva, its features and functions, may be found at the Miva web site.

Currently, there is no cost for the use of the Miva Empresa Engine -- it is provided to our Virtual Server Administrators free of charge. However, this is dependent on the vendor and is subject to change.

How Does Miva Work?
The Miva pre-processor--that is, the executable--reads the enhanced tags and outputs standard HTML to the browser. These additional Miva embedded tags include such commands like <MvIF>, <MvELSE>, <MvWHILE, <MvEVALUATE>, <MvLET>, <MvASSIGN>, <MvFUNCTION>, <MvCALL>, <MvHIDE>, <MvEXIT>, <MvOPEN>, <MvCLOSE>, <MvIMPORT>, <MvEXPORT>, <MvADD>, <MvDELETE>, <MvMAKEINDEX>, <MvPACK>, and more.

Miva works with Java, JavaScript, VBScript, and all browsers. Miva is also supported by HoTMetal PRO 5.0 from SoftQuad, a powerful web development solution for authoring and publishing sophisticated web sites.  For a more thorough presentation about the Miva technology see the Miva Engine page at the Miva web site.

Installing Miva
To install Miva on your Virtual Server, simply telnet or SSH to your server and run the following install script at the command prompt:

    % cd
    % /usr/local/contrib/miva-install

 

Although this release should be backwards compatible, the miva-install script does not replace any existing Htmlscript files from prior distributions. Therefore, if you are upgrading, we strongly advise you to concurrently run both Miva and the prior version of htmlscript to ensure that your existing applets do not introduce any unknown bugs. If errors are reported, we recommend that you make the necessary conversion to your htmslcript applets so that you can take advantage of the support for and performance enhancements of the new Miva release.

The distribution is bundled with many ready to run applications. These are also available at http://www.miva.com/products/engine/mia/templates/.
