A workaround to get a very compact • separated Latex bibliography. Latex wizardry framework for the pseudobib.tex file found here: https://tex.stackexchange.com/questions/165000/condense-non-numbered-bibliography-into-one-line
Usage: This requires the python package bibtexparser. Like compiling a normal bibtex file, you first add the citations to both the .tex and .bib files. Then, run
python3 bib_to_pseudobib.py mwe.tex mwe.bib
This will generate pseudobib.tex. Now, instead of calling \bibliography{mwe.bib}, we call \input{pseudobib}. Your tex file should now compile with the bibliography as normal (compile twice as usual to link the \cite commands to the updated bibliography)!
Note:
If bib_to_pseudobib.py runs in an error that involves the journal_mapping dictionary, it is likely due to a bibtex entry with a journal field not covered by that dictionary. You may solve that by adding manually the appropriate item to that dictionary definition in bib_to_pseudobib.py.
