使用 doi 包時，強制 bibtex 以大寫形式排版 doi

Question

的一個變體這個問題這增加了解決方案與套件一起使用的額外要求doi。

如何強制 bibtex 將下面的單字「DOI」格式化為大寫？

\documentclass{article}
\usepackage{natbib}
\usepackage{doi} % hyperlink URLs

\begin{filecontents*}{\jobname.bib}
@article{milner92,
 author  = {Robin Milner and Joachim Parrow and David Walker},
 title   = {A Calculus of Mobile Processes, {I} and {II}},
 journal = {Inf. Comput.},
 volume  = {100},
 number  = {1},
 pages   = {1--77},
 year    = {1992},
 doi     = {10.1016/0890-5401(92)90009-5},
}
\end{filecontents*}

\begin{document}
\cite{milner92}

\bibliographystyle{plainnat}
\bibliography{\jobname}
\end{document}

Answer 1

正如文檔所說：

doi的格式可以透過重新定義\doitext指令來控制，

\documentclass{article}
\usepackage{natbib}
\usepackage{doi} % hyperlink URLs
\renewcommand{\doitext}{DOI:~}
\begin{filecontents*}{\jobname.bib}
@article{milner92,
 author  = {Robin Milner and Joachim Parrow and David Walker},
 title   = {A Calculus of Mobile Processes, {I} and {II}},
 journal = {Inf. Comput.},
 volume  = {100},
 number  = {1},
 pages   = {1--77},
 year    = {1992},
 doi     = {10.1016/0890-5401(92)90009-5},
}
\end{filecontents*}

\begin{document}
\cite{milner92}

\bibliographystyle{plainnat}
\bibliography{\jobname}
\end{document}
