Development with Code Generation

Tools

• In csharp/ICT/PetraTools
• uses CSParser to parse existing C# files
• write code:
  • can comment generated code
  • can insert regions with name ManualCode (need endregion ManualCode as well)

• TODO: write into Templates
• Plugin writers for different output (Winforms, GTK, ASP.net)
• See detailed documentation for developers: Developing the Forms generator

YAML

YAML is a text file format that is shorter and easier to write and read than XML, but you can get the same structure than XML. This is achieved by not having opening and closing tags, but by using identation to define the hierarchy of elements. It is more friedly to read than XML, since it is less technical (no markup!).

• Overview
• Official specification
• Parsers
  • see a parser for YAML: http://yaml-net-parser.sourceforge.net/default.html
  • For openPETRA we have developed our own converter from yaml to xml: project Ict.Tools.CodeGeneration, Yml2Xml.cs, Ict.Tools.CodeGeneration.Yml2Xml
    • Advantage: we can write short yaml code, but can use the comfort of the XML parser in .Net to walk through the hierarchy
    • yml2xml maps the YAML into XML

openPETRA YAML syntax

Specific syntax is used in openPETRA for

• defining the hierarchy of Namespaces

(csharp\ICT\Petra\Definitions\NamespaceHierarchy.yml)

• defining the navigation menu hierarchy

(csharp\ICT\Petra\Definitions\UINavigation.yml)

• defining the cached datatables
  • csharp\ICT\Petra\Definitions\CacheableTablesAndLists.yaml
  • see also Documentation Cacheable Tables
• screen definition files (see Documentation_YAML_for_OpenPetra_Forms)
