Output/save key replacements when merging #267
Description
I want to merge multiple latex projects into one and would like to use bibtex-tidy for merging the bibliographies. However, if entries are merged, only the first entry's key survives the merge and the duplicate keys are lost. It would be very helpful to have the option to output all key replacements to a file or a separate output field in the web app, so that they can be used in a find-replace script to fix the latex sources.
Example: There are two entries with keys riemann1859 and anzahlprim, both having the same title Ueber die Anzahl der Primzahlen unter einer gegebenen Grösse.. If I use the deduplication option by title, both entries will be merged and the key anzahlprim is lost. This means that all latex sources referencing anzahlprim now have an undefined reference. If I had a list of the form
anzahlprim riemann1859
<other-lost-key> <replaced-by>
I could run an easy script that replaces all references to anzahlprim with riemann1859 in the latex sources.
Is there already a way to do this? E.g. the CLI could get a flag --save-key-replacements <file-path> and the web app a simple output text field.
