--- Comment #2 from Thomas Fischer <fisc...@unix-ag.uni-kl.de> ---
I agree that this is a useful feature. I was able to make a basic
implementation, but I want to check it first with a fresh pair of eyes before
pushing it to the Git repo.
Regarding the source code, you were on the right track. To have a sorted
output, one has to look into FileExporterBibTeX::saveAsString(.., const File
*). There, I introduced
const File *_bibtexfile = sortedByIdentifier ?
File::sortByIdentifier(bibtexfile) : bibtexfile;
... and use a search&replace to make use of _bibtexfile instead of the original
bibtexfile in the remainder of this function.
File::sortByIdentifier(..) is a new function that basically employs
std::sort(..) with a custom comparison function to get the desired result.
To make it more useful, the code expands on
FileImporterBibTeX::Private::Statistics to track if two subsequent entries' ids
are in lexicographic order. When opening a BibTeX file, based on this counter
it is guessed if this file is "sorted" or not. This information is tracked as a
file property and then used when saving a file as described above.
The property can also toggled in the per-file properties widget. Activating it
will only have an effect when writing. Deactivation has no practical effect,
there is no shuffling in this case ;-)
