For-like loop in .ini configuration file

[Alex Shpiner]

Hi,

Is is possible to define for-like loop in the .ini files?

For example, assume that I have an array of hosts (host[*]) and I need to set some parameter based on the index in the array like:
**.host[i].my_index = i

Is there a way to do it in the .ini file? 

Thanks,
Alex.

There is a possibility to define loops / iterations for parameter studies...
Check the chapter 9.4 and the following subsections (especially 9.4.2, 9.4.3 and 9.4.5) in the OMNeT manual, maybe you can use those structures to get what you want.

**.host[i].my_index = parentIndex()

However I don't see why you need this in the INI file. In C++ code you can access the index directly using C++ API

Thanks Michael.
I read this chapter. It is not enough for me, since I need the configuration for a single simulation and not for separate runs.

Thanks Rudolf.
Indeed I wasn't aware of the parentIndex() function. I would propably use it in some configurations.
Yet, I feel that a function that returns my index instead of parent index is what would fit my needs best. I couldn't find that in the manual.
Of course, I could adapt the C++ code to do that, and, actually, avoid INI configurations at all, but configure it in the INI seems more natural.

I succeed to use index() to get my index in the INI file.
It is not documented in the manual.

Actually it is :)

For historical reasons it is implemented as an operator (so it is part of the language) and not as a function.

For completeness: int ancestorIndex(int numLevels) is also available. This one is the most generic function in this regard.
