💅 bbl2bib — the manual page, but make it make sense

okay bestie, so bbl2bib(1) is a page from the LATEX CROSSREFWARE family, and it's here to teach you about bbl2bib.pl — the little script that converts a thebibliography environment into a bib file. yes. that's the whole vibe. sit down, hydrate, let's go 🫶

✨ NAME ✨

bbl2bib.pl — convert the thebibliography environment to a bib file

it's giving "glow-up for your bibliography," fr fr.

🌸 SYNOPSIS 🌸

bbl2bib.pl [-d] [-u] [-o output] file

that's the whole shape of it. one file goes in, one bib file (probably) comes out. iconic behavior.

🎀 OPTIONS 🎀

  • [-d] — sends debugging output to stdout. so if you're nosy (valid) and wanna watch the script think, this is your moment 💖
  • -o output — the output file, obviously. if you don't use this option, the name for the output file is formed by changing the extension to ".bib". so it just. names itself. main character energy.
  • -u — do not clean URL fields. okay so listen: normally "bbl2bib" recognizes URL fields of the kind "http://dx.doi.org" and their variants and converts them to DOI fields (see also the biburl2doi(1) script). this switch -u suppresses that cleanup. so if you want the URLs left exactly as they are, bestie, say -u and it will not touch them ✨

💜 DESCRIPTION 💜

the script tries to reconstruct a "bib" file from the corresponding "thebibliography" environment. and like. one can argue that this operation is akin to reconstructing a cow from the steak. yes, that's a real thing this manpage says, and honestly? it ate. 🥩➡️🐄

the way the script does it is by searching for the entry in the MR database, and creating the corresponding BibTeX fields. that's the move.

so the script reads a TeX or Bbl file, extracts the "thebibliography" environment from it, and for each bibitem it creates a plain text bibliography entry, and then tries to match it in the database. detective mode activated 🔍✨

🦋 INPUT FILE 🦋

we assume some structure of the input file, and bestie, the script is not flexible about this. it needs the vibes to be right:

  1. the bibliography is contained between the lines
\begin{thebibliography}...

and

\end{thebibliography}
  1. each bibliography item starts from the line
\bibitem[...]{....}

that's it. that's the contract. respect the structure and it'll respect you 💅

🌈 EXAMPLES 🌈

bbl2bib  -o - file.tex > result.bib
bbl2bib  -o result.bib file.bbl
bbl2bib  file.tex

look at these. three little baddies. one pipes to stdout with -o -, one names its own output file, and one just raw-dogs it and lets the default naming happen. obsessed. 🔥
