BibTeX source should not start with two empty lines

[koppor]

Due to #391, the "BibTeX source" contains two empty lines. This is explainable when discussing the implementation, but not understandable why JabRef breaks with the existing display of source and why users have to see two empty lines for each entry.

The source in the "BibTeX source tab" should contain the content from @ until }.

Current state:

Wanted display:

The only enhancement I would agree if comments in front of the entry would be stored. Currently, JabRef does not support comments.

Should be terribly easy to implement by using trim() in the preview panel, shouldn't it? Just go ahead and fixt it.

Side effect: When I use "send as Email", I also want to have the same rendering as in the BibTeX source. What if I do an HTML export? Then I also want to get the trimmed representation. What of other accesses of the BibTeX source. Does that quick fix really work for all usages?

[lenhard]

We could offer a second getter for the representation getTrimmedSerialization or something similar. Then it really depends on the use case. I cannot tell if trim() is appropriate in all cases, but at least it is in yours :) I wrote the getParsedSerialization with file writing in mind.

What is the reason for this two empty lines? Personally I would always expect the serialization of a sole entry to start with @ and end with }.

[lenhard]

Because we decided that entries that have not changed should be written back exactly as they were read from the file: #116 That means newlines have to stored somewhere and prepending newlines are stored with the parsed serialization of an entry.

It seems that the entry editor uses the getParsedSerialization method from BibEntry and, therefore, displays the entry exactly as it was read from the file (including newlines).

[koppor]

It cannot be changed easily as it goes through the BibEntryWriter.

This has already been fixed with JabRef 3.2.
