# Minimal BST File That Writes Something

For another question here, I am trying to create a minimal BibTeX style that writes something into the output file.

I am following the instructions from the manual (page 35), where a minimal example is indicated as

ENTRY {}{}{}

FUNCTION {test}
{"de la Cierva y Codorn{\’\i}u, Juan"
#1 "{ff - }{vv - }{ll}" format.name$top$}

EXECUTE{test}


So, as a minimal setup, I created these files:

test.tex

\documentclass{article}

\begin{document}

This is a statement backed with a reference~\cite{Example}.

\bibliographystyle{test}
\bibliography{test}

\end{document}


test.bib

% This file was created with JabRef 2.6.
% Encoding: UTF8

@ARTICLE{Example,
author = {Sally Sample and Eddie Example},
title = {An Example Paper For Your Bibliography},
journal = {International Journal of Exemplary Text Fragments},
year = {2012},
volume = {3},
pages = {42--49},
owner = {haagfn},
timestamp = {2014.05.02}
}


test.bst

ENTRY {}{}{}

FUNCTION {output.something}
{
"test" write$} READ EXECUTE {output.something}  According to the manual, the write$ command

write[s] S in the output .bbl file.

(with S being the item on the stack right below write$) For compilation, I'm using these commands: pdflatex test.tex bibtex test.aux pdflatex test.tex bibtex test.aux pdflatex test.tex  However, my .bbl file remains empty. Oddly, when I replace write$ with top\$ (as in the example from the manual), test does get output in the terminal. However, to make my example as true to the real use case as possible (and also because I want to know how it works), I would like to output my example string to the .bbl file.

Why does my .bbl file remain empty and what do I have to change so test gets output there?

Your demo shows test.bbl: I assume you mean the input is in test.bst –  Joseph Wright May 2 '14 at 7:09
@JosephWright: Whoops, of course. Thanks, corrected. Got confused with the file extensions while writing the question, the actual file is indeed named test.bst. –  O. R. Mapper May 2 '14 at 7:10
