The Raincode TIALAA Compiler

The AppBuilder compiler for .NET and .NET Core

The Raincode TIALAA (There Is A Life After AppBuilder) Compiler supports AppBuilder raw language in its current form (rules, sets, views) and compiles and deploys it without any additional proprietary component.

Applications can be migrated seamlessly and the Visual Studio® plug-in provides a comfortable and productive development environment.

The Raincode TIALAA Compiler facilitates new development in C# and eliminates the burden of AppBuilder licensing costs.

  • Generates fully verified MSIL using Microsoft Roslyn Framework

  • Visual Studio plug-in allows for source-level debugging

  • Converts panels to XAML files allowing them to be maintained directly from Visual Studio

  • Handles GUI events from Visual Studio and connects them to converse constructions in the rules

  • Handles AppBuilder rules without changes

Raincode TIALAA compiler functionality

  • Handles AppBuilder rules without changes

  • Handles AppBuilder bind files for views/sets/…

  • Handles AppBuilder MMRef files for sets

  • Compiles each rule, view, set to a signed DLL

  • Produces efficient native .NET code (IL)

  • Provides multi-language support

  • Supports embedded SQL calls

  • Supports calling external components

  • Provides an interface to call rules from C# or VB

  • Syntax highlighting for rules in VS

  • Debugging across languages

Server-side Rules

  • All AppBuilder rule language constructs supported including MAP, OVERLAY, USE, DCL blocks with LIKE, VIEW CONTAINS, etc…

  • Library functions such as CHAR, SUBSTR, and DELETE are redefinable.

  • Views are compiled from a Nebula bind file and become native .NET classes

  • USE COMPONENT can call COBOL components, C# components, or anything with a known interface

  • SQL ASIS can execute per client customer SQL commands


  • Rules work similarly to server-side rules

  • Panels are migrated once with each panel becoming a native XAML file; no more HpsPanel

  • MLS through a proper .NET resource dictionary created by collecting panel definitions

  • Event handling compiler generates and connects handlers

  • Data binding using pure XAML; no “magic” with TwoWay-connecting to observable fields

  • Manipulates GUI objects with TIALAA GUI Bridge”, replacing AppBuilder ObjectSpeak

  • System components reimplemented
