feature request: quiet mode for version controlled bib files

[thorade]

My .bib file is under version control. It would be nice to have a quiet mode that does not print the error messages (or at least not to the file, maybe to stdout or some logfile instead). Then I could use betterbib to enhance just those entries that are indexed by Crossref. Also, in quiet mode do not add the source = {CrossRef}, field.
Just a suggestion, does not have high priority. And thanks again for your script!

Thinking about it: What I really want to do is add DOIs where possible. No other changes.

They are added if available from CrossRef. What else do you have in mind?

[thorade]

Yes, they are added and that is great! But some fileds are changed (e.g. \"a is changed to ä in title or author name), and the source field is added, and some comments are printed. But what if I only want to add DOIs and not change the file otherwise (umlauts will break my workflow, additional fields or comments would upset collaborators)? Currently, some manual steps are required. Not a problem, because the DOIs only need to be added once.
I do not know how this could be solved elegantly.
Feel free to just close this as out of scope.

So basically you'd like to keep everything, and only add the DOI when available? This use case seems a little too specific for including it into betterbib, but you can easily do it yourself. Basically I'd copy over betterbib to add_doi (or whatever you want to call it) and instead of writing the result of pybtex_to_bibtex_string(result, bib_id) to the output file, use the original data plus the DOI from result.
