Re: value_string from file

The RADIUS and Diameter dissectors also read most of their value_strings
(and other things) from files.

Hi,

While not ideal, it can be done. Have a look at packset-tpncp.c and the
wimaxasncp plugin

Thanks,

Hi,

I am developing a dissector for ISO11783 (ISObus) which is using object
IDs which are constant per application. I have a file where these values
are defined which I would like to read in my dissector so it is easier to
see what is happening. What I was wondering about if this has been done
before already and if not would it be advisable to do this or can I better
display numbers and let the conversion up to the user?

The way I would like to implement it is as follows:
- Define a way to define the number to string definition, most likely csv
- Add an option in preferences to indicate where this file is located
- At startup or change of setting read this file and generate a
string_value object

At the moment the amount of values is around 5000, but the protocol
supports 65534 values. We would like to make this dissector available for
public use as soon as it is ready.
