11.3 xdkconv

This section is about the standalone grammar file converter of the XDK (xdkconv). The grammar file converter takes a source grammar file and converts it into a destination grammar file. The grammar file language into which the destination grammar file is converted depends on its suffix.

The source grammar file can be one of the following:

• UL file (suffix: ul)
• XML file (suffix: xml)
• IL pickle (suffix: ilp)
• IL functor¹ (suffix: ozf)

And the destination grammar file can be one of the following:

• UL file (suffix: ul)
• XML file (suffix: xml)
• IL pickle (suffix: ilp)

11.3.1 Invocation

These are the commandline arguments of xdkconv:

• --help or --nohelp (short version: -h): Display an overview of the commandline arguments. Default: --nohelp.
• --grammar (-g): Select the source grammar file. Default: "".
• --output (-o): Select the destination grammar file. Default: "".
• --debug or --nodebug (-d): Switch on the debug mode. Default: nodebug.

11.3.2 Example

Here is an example. Assume you would like to convert the source grammar file Grammars/Diplom.ul, which is written in the User Language (UL) into the destination grammar file Grammars/Diplom.xml in the XML language. Here is how you do this with xdkconv:

     xdkconv.exe -g Grammars/Diplom.ul -o Grammars/Diplom.xml

xdkconv reads the UL grammar Grammars/Diplom.ul, and saves the corresponding XML language grammar Grammars/Diplom.xml.
