Output file format

[gabrielfougeron]

I copied the format of you two (short and long) tests. Check if file format is ok.

New variables Is it a problem if I add new variables in the output format (e.g. total energy) ? Do I have to somehow "tell" you, or isthe JSON format conveniant enought that it allows you to discard them ? (until needed)

Order New lines should be added at the beginning of the file. See testCases.md on branch plotter for more details.

If necessary, see http://stackoverflow.com/questions/7110616/fortran-how-to-write-data-to-specific-line-in-the-file.

You can add all what you want provided that the <key,value> I need remain (x, t and m for the moment).

I will be able at any moment to parse new variables you would have added to the output file.

Output file at https://github.com/giulioforesto/planets/blob/master/Planets-simulator/output/outfile.txt is almost ok. But for x and m I need them to be:

{
    "t": <long>,
    "x": {
        "id1": [<float>, <float>],
        "id2": [<float>, <float>]
    },
    "m": {
        "id2": <float>
    }
}

Print output routine updated.

Cannot unfortunately write new line at the beginning of file without overwriting the current line

Gonna try to read backwards then.

Hang tight...

Remember that a "refresh" function might provide an easy (and totally fine) work-arround

[giulioforesto]

I should be able to read backwards, need file example to test.
Otherwise, non-live representation or refresh feature are possible, so the issue about the writing order will be closed as soon as I can check the revised output file example.

Edit: output file is ok. live-representation issues must be discussed in new issue.
