+
+This LaTeX package helps you typeset an
+[Extended Backus-Naur Form](https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form) (EBNF)
+using plain text format.
+
+First, [install it](https://en.wikibooks.org/wiki/LaTeX/Installing_Extra_Packages)
+from [CTAN](https://ctan.org/pkg/naive-ebnf)
+and then use in the preamble:
+
+```text
+\documentclass{article}
+\usepackage{naive-ebnf}
+\begin{document}
+\begin{ebnf}
+<Expression> := <Variable>
+ | "$\lambda$" <Variable> "." <Expression>
+ | "(" <Expression> <Expression> ")"
+\end{ebnf}
+\end{document}
+```
+
+Otherwise, you can download [`naive-ebnf.sty`](https://raw.githubusercontent.com/yegor256/naive-ebnf/gh-pages/naive-ebnf/naive-ebnf.sty) and add to your project.
+
+## How to Contribute
+
+If you want to contribute yourself, make a fork, then create a branch,
+then run `l3build ctan` in the root directory.
+It should compile everything without errors. If not, submit an issue and wait.
+Otherwise, make your changes and then run `l3build ctan` again. If the build is
+still clean, submit a pull request.

+% \section{Introduction}
+%
+% This package helps render a
+% \href{https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form}{Extended Backus-Naur Form}
+% using plain text notation:
+% \begin{docshot}
+% \documentclass{minimal}
+% \usepackage{naive-ebnf}
+% \usepackage{mathtools}
+% \begin{document}
+% \begin{ebnf}
+% <Expr> := <Var>
+% | "$\lambda$" <Var> "." <Expr>
+% | "$\lparen$" <Expr> <Expr> "$\rparen$"
+% \end{ebnf}
+% \end{document}
+% \end{docshot}
+
+% The following syntax is understood inside the |ebnf| environment:
+% \begin{itemize}
+% \item |:=| separates the left-hand side from the right-hand side of the production rule;
+% \item |<...>| denotes a non-terminal (variable);
+% \item |"..."| denotes a terminal symbol;
+% \item \texttt{(...\char`\|...)} denotes a series of options to choose from;
+% \item |[...]| denotes an optional substitution;
+% \item |{...}| denotes a zero or more times repetition;
+% \end{itemize}
+
+% \textbf{Attention}: The usage of some symbols is prohibited inside terminals. Instead, the following substitutions are recommended:
+% \begin{itemize}
+% \item |$\lparen$| and |$\rparen$| instead of ``|(|'' and ``|)|'' (from the \href{https://ctan.org/pkg/mathtools}{mathtools} package);
+% \item |$\langle$| and |$\rangle$| instead of ``|<|'' and ``|>|'';
+% \item |$\lbrace$| and |$\rbrace$| instead of ``|{|'' and ``|}|'' (also |mathtools|);
+% \item |$\lbrack$| and |$\rbrack$| instead of ``|[|'' and ``|]|'' (also |mathtools|);
+% \item |$\vert$| instead of ``\texttt{\char`\|}''.
+% \end{itemize}
+
+% \DescribeMacro{\terminal}
+% \DescribeMacro{\nonterminal}
+% Inside the text, terminals and non-terminals may be formatted using two supplementary commands:
+% \docshotOptions{firstline=6,lastline=10}
+% \begin{docshot}
+% \documentclass{article}
+% \pagestyle{empty}
+% \usepackage[paperwidth=3in]{geometry}
+% \usepackage{naive-ebnf}
+% \begin{document}
+% The non-terminal \nonterminal{Var}
+% in $\lambda$-calculus may be equal
+% to $v_1, v_2, \dots$. Application
+% starts with \terminal{(} and ends
+% with \terminal{)}.
+% \end{document}
+% \end{docshot}
+
+% \section{Package Options}
+
+% It's possible to configure the behavior of the package with the help of a few package options:
+
+% \DescribeMacro{bw}
+% By default, some colors are used in the rendered grammar. However, the |bw| package option disables any colors and makes sure the gammar is black-and-white:
+%\iffalse
+%<*verb>
+%\fi
+\begin{verbatim}
+\usepackage[bw]{naive-ebnf}
+\end{verbatim}
+%\iffalse
+%</verb>
+%\fi
+
+% \StopEventually{}
+
+% \section{Implementation}
+% \changes{0.0.1}{2023/01/28}{First draft.}
+% \changes{0.0.2}{2023/01/29}{Proper parsing of grouping.}
+% \changes{0.0.2}{2023/01/29}{Substitutions suggested for special symbols.}
+
+% First, we process package options:
+% \begin{macrocode}
+\RequirePackage{pgfopts}
+\pgfkeys{
+ /ebnf/.cd,
+ bw/.store in=\ebnf@bw,
+}
+\ProcessPgfPackageOptions{/ebnf}
+% \end{macrocode}
+
+% Then, we include a few packages, mostly to deal with \LaTeX{}3 expressions:
+% \begin{macrocode}
+\RequirePackage{filecontentsdef}
+\RequirePackage{expl3}
+% \end{macrocode}
+
+% \begin{macro}{\ebnf@color}
+% Then, we include \href{https://ctan.org/pkg/xcolor}{xcolor} to colorize the output a bit:
+% \begin{macrocode}
+\makeatletter\ifdefined\ebnf@bw\else
+ \RequirePackage{xcolor}
+\fi
+\newcommand\ebnf@color[2]
+ {\ifdefined\ebnf@bw#2\else\textcolor{#1}{#2}\fi}
+\makeatother
+% \end{macrocode}
+% \end{macro}
+
+% \begin{macro}{\terminal}
+% \changes{0.0.2}{2023/01/29}{New command \texttt{\char`\\terminal} added, to enable rendering terminal symbols outside of the \texttt{ebnf} environment.}
+% Then, we a command to render a single terminal:
+% \begin{macrocode}
+\makeatletter
+\newcommand\terminal[1]{%
+ \relax\ifmmode\else\ttfamily\fi%
+ \ebnf@color{gray}{"}#1\ebnf@color{gray}{"}}
+\makeatother
+% \end{macrocode}
+% \end{macro}
+
+% \begin{macro}{\nonterminal}
+% \changes{0.0.2}{2023/01/29}{New command \texttt{\char`\\nonterminal} added, to enable rendering non-terminal symbols outside of the \texttt{ebnf} environment.}
+% Then, we a command to render a single non-terminal:
+% \begin{macrocode}
+\makeatletter
+\newcommand\nonterminal[1]
+ {\(\ebnf@color{gray}{\langle}\textsf{#1}\ebnf@color{gray}{\rangle}\)}
+\makeatother
+% \end{macrocode}
+% \end{macro}
+
+% Then, we define supplementary commands:
+% \begin{macrocode}
+\makeatletter
+\newcommand\ebnf@optional[1]
+ {\ebnf@color{gray}{[}#1\ebnf@color{gray}{]}}
+\newcommand\ebnf@repetition[1]
+ {\ebnf@color{gray}{\{}#1\ebnf@color{gray}{\}}}
+\newcommand\ebnf@grouping[1]
+ {\ebnf@color{gray}{(}#1\ebnf@color{gray}{)}}
+\ExplSyntaxOn
+\newcommand\ebnf@terminal[1]{
+ \tl_set:Nn \l_ebnf_tl { }
+ \tl_set_rescan:Nno \l_ebnf_tl { } { #1 }
+ \terminal{\l_ebnf_tl}
+}
+\ExplSyntaxOff
+\newcommand\ebnf@to
+ {\ebnf@color{gray}{\(\to\)}}
+\newcommand\ebnf@alternation
+ {\ebnf@color{gray}{\(\vert\)}}
+\newcommand\ebnf@eol{\\}
+\makeatother
+% \end{macrocode}
+
+% \begin{macro}{ebnf}
+% Then, we define the |ebnf| environment:
+% \begin{macrocode}
+\ExplSyntaxOn
+\cs_generate_variant:Nn \tl_replace_all:Nnn {Nx}
+\NewDocumentEnvironment{ebnf}{}{\filecontentsdefmacro\l__ebnf_tmp_tl}{
+ \endfilecontentsdefmacro
