I have a model and want to export the run parameters to a log file. The idea is to get the following example into a decent text export:

a = 1;
b = 2;
c = 3;

p = Style[Grid[{
    {"Parameter a ", a},
    {"Parameter b ", b},
    {"Parameter c ", c}
    }]
  , Bold, Blue]

Export["_log.txt", p];

The problem here is, that the output includes all the Grid commands, which I obviously don't want. Just a somewhat neatly arranged text file.

More precisely: the above code gives the following log file>

The log file I'd like to have should look like>

  • $\begingroup$ Please make it clear what you are trying to achieve. Give both a sample input (you have this) and a sample output (you didn't show this). $\endgroup$

  • $\begingroup$ OK, great: Export["Desktop/_log.txt", ExportString[p, "Table"]] at least produces a simple log file I can use. Thanks! However, I am wondering how it is possible to export a more complex info file. But for now, that is sufficient. $\endgroup$

You have wrapped your data with UI specific calls that makes sense only the UI. And then wanted to export it to a text file, which is not a good way to go about things.

You should have your data separate from the UI specific wrappers, then you can export your data on its own, or use the wrappers on it for UI display. Look at InputForm[p] and you can see what you have now.

Instead you can do this

a = 1;
b = 2;
c = 3;
data = {{"Parameter a ", a}, {"Parameter b ", b}, {"Parameter c ", c}};
p = Style[Grid[data], Bold, Blue]

SetDirectory[NotebookDirectory[]]
Export["foo.txt", data]

And this is the text file

  • $\begingroup$ Right, I tried this, but I don't want the brackets or quotations marks, just some neat, simple text, maybe comma separated, but just text. $\endgroup$

    $\begingroup$ @MockupDungeon Try Export["foo.txt", data, "Table"]. $\endgroup$
