IBM InfoSphere Streams Version 4.1.1

Installing the Uncrustify source code formatter for InfoSphere Streams

When you generate C++ code using the sc command or Streams Studio, InfoSphere® Streams can use the Uncrustify source code formatter to ensure that the generated code is indented and formatted correctly. Installing and using the Uncrustify source code formatter with InfoSphere Streams is optional.

If you specify the code beautification option (-z) when you compile your code, and the Uncrustify software is not installed, the following message is displayed:

CDISP9094W WARNING: The 'uncrustify' code formatter could not be found.
Compilation is continuing without formatting.

Procedure

Download the Uncrustify source code formatter from the Uncrustify website.
Install the source code formatter by using the instructions on the Uncrustify website.
Edit the Uncrustify configuration file that is provided by InfoSphere Streams.
The uncrustify.verbose.cfg file is included in the InfoSphere Streams installation. You can edit this file to customize the formatting. This file is in the product-installation-root-directory/4.1.1.0/etc/uncrustify directory. For more information about modifying the configuration file, go to the Uncrustify website.

Note: Source code formatting can introduce an error in the generated C++ code. If you specify the code beautification option (-z) when you compile your code and an error is displayed when you compile the generated C++ code, try compiling your code without the -z option to ensure that the error is not introduced by the source code formatter.
