bib2wiki

bib2wiki is a perl script to generate a template to cite scientific references on this very website from its $\mathrm{B{\scriptstyle{IB}}\TeX}$ entry.

This is, for instance, an old paper of ours: Electrostatic control of quantum dot entanglement induced by coupling to external reservoirs. E. del Valle, F. P. Laussy and C. Tejedor in Europhys. Lett. 80:57001 (2007).

The rationale is explained in this blog post and examples of its use are in this other blog post. Undefined references can be fixed with keys2wiki.

It supports Bash autocompletion, as is declared in showme.

It is based on BibTeX::Parser.

Usage

# Usage: 
# To print one key:
#   bib2wiki laussy04a
#
# To print several keys:
#   bib2wiki -keys=laussy04a,laussy05a,laussy06a
#
# To print everything:
#   bib2wiki -keys=all

Script

• All versions till v0°5 were written on 16 July (2023).
• v0°6 was written on 22 October (2023) to interface with keys2wiki (clearing the screen).
• v0°7 was written on 31 December (2023).
• v1°0 was updated on 16 September (2025) — it merely outputs the key in bold yellow (and fixes the î which requires special escape), but the code is robust and useful enough to warrant a 1.0 label.
