使用 BibLaTeX 來源圖的縮排附錄

Question

我正在嘗試產生一個帶註釋的參考書目，其中每個條目都有一個摘要段落，以便每個參考文獻的附錄出現在比條目本身深一級縮排的新行上。

對於每個條目

addendum = {Text.}

以下似乎運作良好，產生了我想要看到的輸出格式：

addendum = {\paragraph\indent{Text.}\\}

我正在嘗試使用以下命令執行自動轉換：

\DeclareSourcemap{
    \maps[datatype=bibtex]{
        \map{
            \step[fieldsource=addendum, 
                match=\regexp{(.*)},
                fieldset=addendum,
                replace={\\paragraph\{\\indent $1\} \\}
            ]
        }
    }
}

但是，我似乎無法在替換字段中正確轉義字符，並且 LaTeX 會產生錯誤：

Undefined control sequence.
\\  ->\let \reserved@e 
                       \relax \let \reserved@f \relax \@ifstar {\let \reserv...
l.68 }

我無法弄清楚這一點 - 我是否錯誤地定義了輸出正規表示式？

測試文件

\documentclass[a4]{article}
\usepackage[backend=biber]{biblatex}

\bibliography{test}

% Sourcemap is placed here.

\begin{document}

Test 1 \cite{test}
Test 2 \cite{test2}

\printbibliography

\end{document}

其中測試 1 是轉換前引用，測試 2 是所需的輸出。

你不需要使用\DeclareSourcemap一個簡單的

\DeclareFieldFormat{addendum}{\paragraph\indent{\textbf{Annotation:}\addspace#1}\\}

足夠了：

\documentclass{article} % [a4] is not a correct option
\usepackage[english]{babel}
\usepackage{filecontents}
\begin{filecontents}{test.bib}
@article{test,
    author    = {Luigi P. Cordella and
        Pasquale Foggia and
        Carlo Sansone and
        Mario Vento},
    title     = {A (Sub)Graph Isomorphism Algorithm for Matching Large Graphs},
    journal   = {{IEEE} Trans. Pattern Anal. Mach. Intell.},
    volume    = {26},
    number    = {10},
    pages     = {1367--1372},
    year      = {2004},
    doi       = {10.1109/TPAMI.2004.75},
    timestamp = {Sat, 12 Mar 2016 09:04:02 +0100},
    addendum = {This is a test of simple annotations.}
}
@article{test2,
    author    = {Luigi P. Cordella and
        Pasquale Foggia and
        Carlo Sansone and
        Mario Vento},
    title     = {A (Sub)Graph Isomorphism Algorithm for Matching Large Graphs},
    journal   = {{IEEE} Trans. Pattern Anal. Mach. Intell.},
    volume    = {26},
    number    = {10},
    pages     = {1367--1372},
    year      = {2004},
    doi       = {10.1109/TPAMI.2004.75},
    timestamp = {Sat, 12 Mar 2016 09:04:02 +0100},
    addendum = {This is a test of simple annotations using biblatex.}
}
\end{filecontents}

\usepackage[backend=biber]{biblatex} 
\usepackage{csquotes} % added
% New format for addendum field
\DeclareFieldFormat{addendum}{\paragraph\indent{\textbf{Annotation:}\addspace#1}\\}
\addbibresource{test.bib} % Not \bibliography{test}

\begin{document}

Test 1 \cite{test}
Test 2 \cite{test2}

\printbibliography

\end{document}
