Formatting Generated Code [message #1809218]

Hello,

I implemented a code generator and the output is a xml file. I would like to have this output formatted. Here is a little example:

Current output (snippet) :

<model xsi:type="...." name="Planned Architecture">
<structureElement xsi:type="..." name="managing_1">
<structureElement xsi:type="..." name="controller_1">
<structureElement xsi:type="..." name="monitor_1">
</structureElement>
</structureElement>
</structureElement>
</model>

Desirable output:

<model xsi:type="..." name="Planned Architecture">
    <structureElement xsi:type="..." name="managing_1">
            <structureElement xsi:type="..." name="controller_1">
                <structureElement xsi:type="..." name="monitor_1">
               </structureElement>
            </structureElement>
    </structureElement>
</model>

I read that IFilePostProcessor should help in my purpose but cannot find enough examples to use it properly.

Regards,

I Wonder in you make improper use of Rich String in the First Place so that you have the Problem at all.

The Second question would be: that is exactly unclear about IFilePostProcessor

Maybe the question is: What are the mechanisms for indenting the file that contains the generated code?. At this moment I just use the default code generator of xtex. As you mention "Rich String" which is part of Xbase, I infer I must create a custom code generator with Xbase in order to indent the code. Am I right?

No if you have a rich string

'''
    Demo
'''

You will see that it distinguishes between whitespace
And grey space .
The gray space will end up in the generated file
So in this case you will get a

     Demo

In the generated file

Same with IF and FOR inside the rich string.

See the generator example in the tutorial
