Use adstex instead!

I recommend using adstex instead of aux2adsbib. This was a fun project for me to write, but adstex is a much more capable utility. Projects that used aux2adsbib should be able to switch to adstex without any modifications.

aux2adsbib

aux2adsbib is a small program that parses a LaTeX .aux file and automatically generates a bibTeX library by querying NASA/ADS.

Usage

In your LaTeX source (say ms.tex), cite references using their ADS code, e.g.,

\cite{2022SoPh..297...22D}

and specify ms.bib as your bibliography,

\bibliography{ms}

Then, compile your LaTeX source as you normally would to produce an .aux file. LaTeX will complain about undefined citations. Next, run aux2adsbib:

aux2adsbib ms.tex

aux2adsbib will parse the ms.aux file for references, look up those codes in ADS, and generate the ms.bib file. Finally, run BibTeX and LaTeX again as normal.
