% \textbf{\color{red}NB!}
% You must run \TeX{} processor with |--shell-escape| option
% and you must have \href{https://www.perl.org}{Perl} installed.
% This package doesn't work on Windows.

% \section{Introduction}
%
% This package scans a |.bib| file for style errors and emits
% warning messages if any issues are found (the package must be included before
% all other bibliography related packages):
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\documentclass{article}
\usepackage{bibcop}
\begin{document}
\bibliographystyle{plain}
\bibliography{main}
\end{document}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% Some warnings may be printed in the \TeX{} log.
% Once the issues in the |main.bib| file are fixed, the warnings disappear.

% Bibcop doesn't pay much attention the formatting of the |.bib| file. It doesn't emit
% warnings if a comma is missed after the last tag in a \BibTeX{} entry or the tags
% and their equation symbols are not aligned. Instead, Bibcop is focused on the content
% of the tags and their possible inconsistencies.

% If the |.sty| file is used directly (without installing it into the \TeX{} tree),
% the |bibcop.pl| file must also be placed next to it --- it is the Perl script that does all the work
% of checking your |.bib| files. The |.sty| is just a simple wrapper around it.

% The |\usepackage{bibcop}| must stay right after |\usepackage{biblatex}|
% (if Bib\LaTeX{} is used), otherwise
% there won't be any warnings from |bibcop|.

% \section{Package Options}

% It's possible to configure the behavior of the package with the help of a few package options:

% \DescribeMacro{verbose}
% The |verbose| package option prints all debugging messages to the \TeX{} log:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[verbose]{bibcop}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{script}
% The package depends on the |bibcop.pl| file, which is a Perl script that does all the work. This file is supposed to be located either in the current directory or in the |texmf-dist/scripts/bibcop/| directory. Using the |script| option the location of the script may be explicitly defined (it is not recommended to use this option unless there is a special demand for it):
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
\usepackage[script=my-perl-script.pl]{bibcop}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \section{The Rules}

% This is a more or less complete list of rules enforced on a |.bib| file:

% \DescribeMacro{types}
% Only |@article|, |@book|, |@inproceedings|, and |@misc| types of \BibTeX{} entries are allowed.
% Everything else, like |@manual|, |@phdthesis|, and many others are simply prohibited.
% The mentioned four should be enough for everything.

% \DescribeMacro{tags}
% There are pretty limited lists of allowed tags for each type of \BibTeX{} entry. The tags
% that are not in the list are prohibited to use.

% \DescribeMacro{doi}
% Every \BibTeX{} entry must have the |doi| tag, which is a unique
% \href{https://www.doi.org}{Digital Object Identifier}
% of the material that you reference. It seems to be a good practice, in order to avoid ambiguity,
% to always mention the DOI.
% It also recommended to use the \href{https://ctan.org/pkg/iexec}{doi} package,
% in order to make all ``|doi|'' fields turned into hyper links.

% \DescribeMacro{caps}
% In the |title|, |booktitle|, and |journal| tags, all major words must be capitalized,
% as it is \href{https://apastyle.apa.org/style-grammar-guidelines/capitalization/title-case}{recommended} by APA:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
title = {A Preliminary Architecture for a Basic Data-Flow Processor}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% Here, the leading ``|A|'' is capital because it opens the title.
% The word ``|for|'' and the article ``|a|'' are minor words, that's why they are in lower case.
% Both parts of the composite word ``|Data-Flow|'' are capitalized.
% Sometimes this rule may need to be violated, when there is custom capitalization, as it is done
% by the author of the paper. In order to do this, the words with custom capitalization
% must be wrapped in curled brackets, for example:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
title = {Structured Programming {with} Go {To} Statements}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{author}
% The |author| must contain a list of authors separated by ``|and|''. Each author
% must have two parts separated by a comma. The first part is the last name of the author,
% the second part is a list of their first names separated by a space, for example:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
author = {Knuth, Donald E. and Duane, Bibby}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% When the list of authors is too long, it's possible to say ``|and others|'':
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
author = {Knuth, Donald E. and others}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% When first names are shortened to a single letter, it has to have a tailing dot.
% A specially pronounced author may be wrapped it in curled brackets, to make Bibcop ignore it:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
author = {{Some author} and {I}}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{shorts}
% It is not allowed to shorten any words aside from the |author| tag, for example this is illegal:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
journal = {J. Log. Comput.}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% This must be replaced with the following:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
journal = {Journal of Logic and Computation}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{brackets}
% The |title|, |booktitle|, and |journal| must be wrapped in double brackets, for example:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
title = {{A Survey of Symbolic Execution Techniques}}
\end{verbatim}
%\iffalse
%</verb>
%\fi
% This is necessary in order to prevent down-casing of capitalized words, which is done by some
% bibliography styles.

% \DescribeMacro{year}
% It is not allowed to mention the year inside the title of a conference or a journal, for example,
% this would be illegal:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
booktitle = {{1994 IEEE International Conference on Computer Languages}},
\end{verbatim}
%\iffalse
%</verb>
%\fi
% The year should only be mentioned in the |year| tag, nowhere else.
% In the |year| tag only numbers are allowed:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
year = {1994},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{month}
% The |month| may contain only a number:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
month = {12},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{volume}
% The |volume| may contain only a number:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
volume = {32},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{number}
% The |number| may contain only a number:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
number = {132},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{pages}
% The |pages| may contain either a number or two numbers separated by a double dash:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
pages = {145--163},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{proceedings}
% The |booktitle| in the |@inproceedings| entry must always start with ``|Proceedings| |of| |the|'',
% as in this example:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
booktitle = {{Proceedings of the International
  Conference on Computer Languages}},
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{arXiv}
% If the |archivePrefix| is present, the |eprint| and the |primaryClass| must also be present and must adhere to the formatting principles of \href{https://arxiv.org/help/arxiv_identifier}{arXiv identifiers}:
%\iffalse
%<*verb>
%\fi
\begin{verbatim}
@misc{bugayenko2021,
  archivePrefix = {arXiv},
  eprint = {2111.13384},
  primaryClass = {cs.PL},
}
\end{verbatim}
%\iffalse
%</verb>
%\fi

% \DescribeMacro{typography}
% All tags in each \BibTeX{} entry are checked for obeying the basic typography rules:
% \begin{itemize}
%   \item No spaces are allowed in front of a comma, a semi-colon, a colon, a dot, a question mark, and an exclamation mark;
%   \item A text may not end with a dot, a comma, a semi-colon, a colon, or a dash;
%   \item A triple dash must be surrounded by spaces.
% \end{itemize}

% \DescribeMacro{Unicode}
% Any non-ASCII characters are prohibited in the entire |.bib| file.

% First, we include a few packages.
% We need \href{https://ctan.org/pkg/iexec}{iexec} for executing Perl scripts:
%    \begin{macrocode}
\RequirePackage{iexec}
%    \end{macrocode}

% Then, we process package options:
%    \begin{macrocode}
\RequirePackage{pgfopts}
\pgfkeys{
  /bibcop/.cd,
  verbose/.store in=\bibcop@verbose,
  script/.store in = \bibcop@script,
}
\ProcessPgfPackageOptions{/bibcop}
%    \end{macrocode}

% \begin{macro}{bibcop.pl}
% Then, we find the Perl script:
%    \begin{macrocode}
\makeatletter
\ifdefined\bibcop@script\else
  \IfFileExists{bibcop.pl}
    {\gdef\bibcop@script{perl ./bibcop.pl}}
    {\gdef\bibcop@script{bibcop}}
\fi
\message{bibcop: The Perl script is at '\bibcop@script'^^J}%
\makeatother
%    \end{macrocode}
% \end{macro}

% \begin{macro}{\bibliography}
% Then, we re-define the |\bibliography| command:
%    \begin{macrocode}
\makeatletter
\ifdefined\bibliography
  \let\bibcop@oldbibliography\bibliography
  \renewcommand\bibliography[1]{%
    \iexec{\bibcop@script\space
      \ifdefined\bibcop@verbose--verbose\fi\space
      --latex '#1.bib'}%
    \message{bibcop: style checking finished^^J}%
    \bibcop@oldbibliography{#1}%
  }
\fi
\makeatother
%    \end{macrocode}
% \end{macro}

% \begin{macro}{\addbibresource}
% Then, we re-define the |\addbibresource| command:
%    \begin{macrocode}
\makeatletter
\ifdefined\addbibresource
  \let\bibcop@oldaddbibresource\addbibresource
  \renewcommand\addbibresource[1]{%
    \iexec{\bibcop@script\space
      \ifdefined\bibcop@verbose--verbose\fi\space
      --latex '#1'}%
    \message{bibcop: style checking finished^^J}%
    \bibcop@oldaddbibresource{#1}%
  }
\fi
