+% \maketitle
+%
+% \begin{abstract}
+% The \pkg{fixdif} package redefines the \cs{d} command in \LaTeX{}
+% and provides an interface to define commands for differential operators.
+%
+% The package is compatible with pdf\TeX, \XeTeX{} and \LuaTeX.
+% Furthermore, the package is compatible with \pkg{unicode-math} package
+% in \XeTeX{} and \LuaTeX.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{The background}
+% It's usually recommended that one should reserve a small skip between
+% the differential operator and the expression before it\footnote{See
+% \url{https://tex.stackexchange.com/questions/14821/whats-the-proper-way-to-typeset-a-differential-operator}.}.
+% Take the following cases as an example:
+% \[f(x)\mathrm{d}x\qquad\mbox{and}\qquad f(x)\d x.\]
+% We usually consider that the example on the right side is better than the
+% one on the left side. The little skip between $f(x)$ and $\d x$ can be
+% regarded as a symbol of the product of $f(x)$ and $\d x$.
+%
+% So some users prefer to define a macro like this:
+% \begin{Verbatim}
+% \renewcommand\d{\mathop{\mathrm{d}}\!}
+% \end{Verbatim}
+% This macro works well in ``display math'' and ``text math'', but we still
+% face three problems:
+% \begin{enumerate}
+% \item The skip before ``d'' would still be reserved in ``text fraction'',
+% which is regarded bad. For example, |$\d y/\d x$| produces
+% $\mathrm{d}y/\,\mathrm{d}x$;
+%
+% \item This |\d| command cannot be used out of math mode. In another word,
+% |\d{o}| would not produce ``\d{o}'' in text;
+%
+% \item The skip between ``d'' and the expression before it can be regarded
+% as a product operator. A product operator is definitely a binary operator.
+%
+% Take |\cdot| ($\cdot$) as an example.
+% A binary operator reserves small skips before and after itself when in
+% ``display math'' or ``text math'' such as $x\cdot y$, but the skips will
+% disappear in ``script math'' or ``script script math'' such as $a^{x\cdot y}$.
+% Thus the small skip should also disappear in script, but |$a^{f(x)\d x}$|
+% still produces $a^{f(x)\,\mathrm{d}x}$ but not $a^{f(x)\d x}$.
+% \end{enumerate}
+% To solve these problems, you can try this package.
+%
+% \section{Introduction}
+% To load this package, write
+% \begin{Verbatim}
+% \usepackage{fixdif}
+% \end{Verbatim}
+% in the preamble. In your document,
+% \begin{Verbatim}
+% \[ f(x)\d x,\quad\frac{\d y}{\d x},\quad\d y/\d x,\quad a^{y\d x}. \]
+% \end{Verbatim}
+% will produce
+% \[f(x)\d x,\quad \frac{\d y}{\d x},\quad \d y/\d x,\quad a^{y\d x}.\]
+%
+% \subsection{When using \pkg{unicode-math}}
+% If you are using \pkg{unicode-math} package with \XeTeX/\LuaTeX{}
+% in your document, you must pay attention to the following items:
+% \begin{itemize}
+% \item If you want to \pkg{amsmath} package, make sure that the
+% \pkg{unicode-math} package is loaded \emph{after} \pkg{amsmath}.
+%
+% \item You had better specify the math font through the \cs{setmathfont}
+% provided by \pkg{unicode-math} in order to avoid bad skip in text fraction
+% like $\d y/\d x$.
+%
+% \item Load the \pkg{fixdif} package \emph{after} \pkg{unicode-math}.
+% \end{itemize}
+% Therefore the correct order is
+% \begin{Verbatim}
+% \usepackage{amsmath}
+% \usepackage{unicode-math}
+% \setmathfont{...}[...]
+% \usepackage{fixdif}
+% \end{Verbatim}
+%
+% \subsection{When using \pkg{hyperref}}
+% If you want to use the \pkg{hyperref} package simultaneously,
+% remember to load \pkg{hyperref} \emph{before} the \pkg{fixdif} package,
+% otherwise the \pkg{hyperref} package will cause conflicts.
+%
+% \subsection{Basic commands and package options}
+% \DescribeMacro{\d}
+% The \pkg{fixdif} package provides a \cs{d} command for the differential
+% operator ``d'' in math mode. When in the text, \cs{d} behaves
+% just like the old \cs{d} command in \LaTeX{} or plain \TeX{} as an
+% accent command. For example,
+% \begin{Verbatim}
+% $\d x$ and \d x
+% \end{Verbatim}
+% will produce ``$\d x$ and \d x''.
+%
+% \paragraph{Set the font of \cs{d}}
+% There are two basic package options to control the \cs{d}'s style in math
+% mode~--- \opt{rm} and \opt{normal}. The default option is \opt{rm}, in whose
+% case |$f(x)\d x$| produces $f(x)\d x$. If you chose the \opt{normal} option,
+% for example
+% \begin{Verbatim}
+% \usepackage[normal]{fixdif}
+% \end{Verbatim}
+% |$f(x)\d x$| would produces $f(x)\,dx$.
+%
+% \DescribeMacro{\resetdfont}
+% Besides the previous two optional fonts, you can reset the font of
+% differential operator ``d'' through \cs{resetdfont} command:
+% \begin{Verbatim}
+% \resetdfont{\mathsf}
+% \end{Verbatim}
+% then |\d x| will produce $\mathsf{d}x$.
+%
+% \paragraph{Control the behavior of \cs{partial}}
+% \DescribeMacro{\partial}
+% In default, \cs{partial} will also be regarded as a differential operator
+% in this package. If you don't like this default setting, you can use the
+% \opt{nopartial} option:
+% \begin{Verbatim}
+% \usepackage[nopartial]{fixdif}
+% \end{Verbatim}
+%
+% \section{Define commands for differential operators}
+% \noindent\emph{Attention! The commands in this section
+% can be used in preamble only!}
+%
+% \subsection{Define commands with a single command name}
+% \noindent\textbf{\cs{letdif}\marg{cmd}\marg{csname}}\DescribeMacro{\letdif}
+% \hfill(preamble only)
+%
+% The \cs{letdif} command has two arguments~--- the first is the newly-defined
+% command and the second is the \emph{name} of a \emph{single} character
+% command (without the backslash on the front). For example,
+% \begin{Verbatim}
+% \letdif{\vr}{delta}
+% \end{Verbatim}
+% then the |\vr| will produce a $\delta$ (|\delta|) with automatic skip
+% before it.
+%
+% Through the \cs{letdif} command, we can redefine a math character command
+% by its name. For example,
+% \begin{Verbatim}
+% \letdif{\delta}{delta}
+% \end{Verbatim}
+% then |\delta| itself will be a differential operator.
+%
+% The second argument \meta{csname} of \cs{letdif} command can be used
+% repeatedly.
+%
+% \noindent\textbf{\cs{letdif*}\marg{cmd}\marg{csname}}\DescribeMacro{\letdif*}
+% \hfill(preamble only)
+%
+% This command is basically the same as \cs{letdif}, but this command will
+% patch a correction after the differential operator. This is very useful
+% when a math font is setted through \pkg{unicode-math} package. For example,
+% \begin{Verbatim}
+% \usepackage{unicode-math}
+% \setmathfont{TeX Gyre Termes Math}
+% \usepackage{fixdif}
+% \letdif{\vr}{updelta}
+% \end{Verbatim}
+% this will cause bad negative skip after |\vr|, but if you change the last
+% line into
+% \begin{Verbatim}
+% \letdif*{\vr}{updelta}
+% \end{Verbatim}
+% you will get the result correct.
+%
+% \subsection{Define commands with multi commands or a string}
+%
+% \noindent\textbf{\cs{newdif}\marg{cmd}\marg{multi-cmd}}\DescribeMacro{\newdif}
+% \hfill(without correction, preamble only)\\
+% \noindent\textbf{\cs{newdif*}\marg{cmd}\marg{multi-cmd}}\DescribeMacro{\newdif*}
+% \hfill(with correction, preamble only)
+%
+% The first argument of these commands is the newly-defined command; and the
+% second argument should contain \emph{more than one commands} or
+% \emph{a string}. For example, if you have loaded the \pkg{xcolor} package,
+% you can use the following line:
+% \begin{Verbatim}
+% \newdif{\redsfd}{\textsf{\color{red}d}}
+% \end{Verbatim}
+% Then you get the |\redsfd| as a differential operator. Take another example,
+% \begin{Verbatim}
+% \newdif{\D}{\mathrm{D}}
+% \end{Verbatim}
+% Then you get |\D| for an uppercase upright ``D'' as a differential operator.
+%
+% If your second argument contains only one command like |\Delta|,
+% you should use \cs{letdif} or \cs{letdif*} instead.
+%
+% These two commands will check whether \meta{cmd} has been defined already.
+% If so, an error message will be given.
+%
+% \noindent\textbf{\cs{renewdif}\marg{cmd}\marg{multi-cmd}}\DescribeMacro{\newdif}
+% \hfill(without correction, preamble only)\\
+% \noindent\textbf{\cs{renewdif*}\marg{cmd}\marg{multi-cmd}}\DescribeMacro{\newdif*}
+% \hfill(with correction, preamble only)
+%
+% These two commands are basically the same as \cs{newdif} and \cs{newdif*}.
+% The only difference is that \cs{renewdif} and \cs{renewdif*} will check
+% whether \meta{cmd} has \emph{not} been defined yet. If so, an error message
+% will be given.
+%
+% \section{The source code}

+% \end{macrocode}
+%
+% \subsection{Control the skip between slash and differential operator}
+% Change the math code of slash ($/$) and backslash ($\backslash$) so that the skip
+% between slashes and differential operators can be ignored.
+% \begin{macrocode}
+\@ifpackageloaded{unicode-math}{
+% \end{macrocode}
+% If the \pkg{unicode-math} package has been loaded, use the \XeTeX/\LuaTeX{} primitive
+% \cs{Umathcode} to change the type of slashes. The numeral ``4'' stands for ``open''.
+% \begin{macrocode}

+ \Umathcode"29F5="4 "0 "29F5
+ \Umathcode"29F9="4 "0 "29F9
+}{
+% \end{macrocode}
+% If the \pkg{unicode-math} package has not been loaded, use the \TeX{} primitive
+% \cs{mathcode} to change the type of slashes. The \cs{backslash} needs to be redefined
+% through \cs{delimiter} primitive too.
+% \begin{macrocode}
+ \mathcode`\/="413D
+ \mathcode`\\="426E % \backslash
+ \def\backslash{\delimiter"426E30F\relax}
+}
+% \end{macrocode}
+%
+% \subsection{Patch the skips around the differential operator}
+% \DescribeMacro{\mup at tch}
+% The following \cs{mup at tch} patches the skip after the differential operator.
+% \begin{macrocode}
+\def\mup at tch{\mathchoice{\mskip-\thinmuskip}{\mskip-\thinmuskip}{}{}}
+% \end{macrocode}
+% The \cs{s at beforep@tch} patches the commands with star (\cs{letdif*}, etc).
+% \begin{macrocode}
+\def\s at beforep@tch{\mathchoice{}{}{\mbox{}}{\mbox{}}}
+% \end{macrocode}
+%
+% \subsection{Declare the package options}
+% Declare the options of the package and execute them.
+% \begin{macrocode}
+\DeclareOption{rm}{\@ifpackageloaded{unicode-math}
+ {\def\@@dif{\symrm{d}}}{\def\@@dif{\mathrm{d}}}}
+\DeclareOption{normal}{\def\@@dif{d}}

+\DeclareOption{nopartial}{\def\fixdif at partial@bool{0}}
+\ExecuteOptions{rm,partial}
+\ProcessOptions\relax
+% \end{macrocode}
+% Control the behavior of \cs{partial}.
+% \begin{macrocode}
+\def\fixdif at partial@true{1}
+\ifx\fixdif at partial@bool\fixdif at partial@true
+ \AtEndOfPackage{\letdif{\partial}{partial}}
+\fi
+% \end{macrocode}
+% \DescribeMacro{\resetdfont}
+% Define the \cs{resetdfont} command.
+% \begin{macrocode}
+\gdef\resetdfont#1{\let\@@dif\relax%
+ \def\@@dif{#1{d}}}
+% \end{macrocode}
+%
+% \subsection{Deal with the \cs{d} command}
+% \DescribeMacro{\@dif}
+% \cs{@dif} is the differential operator produced by \cs{d} in math mode.
+% Here we prefer \cs{mathinner} to |\mathbin| to make the skip.
+% \begin{macrocode}
+\def\@dif{\ifmmode%
+ \mathinner{\@@dif}\mup at tch%
+\fi}
+% \end{macrocode}
+% \DescribeMacro{\d at accent}
+% Restore the \cs{d} command in text by \cs{d at accent} with the \cs{let}
+% primitive.
+% \begin{macrocode}
+\let\d at accent\d
+% \end{macrocode}
+% \DescribeMacro{\d}
+% Redefine the \cs{d} command. In text, we need to expand the stuffs after \cs{d}
+% \begin{macrocode}
+\gdef\d{\ifmmode\@dif\else\expandafter\d at accent\fi}
+% \end{macrocode}
+%
+% \subsection{User's interface for defining new differential operators}
+% \DescribeMacro{\letdif}\DescribeMacro{\letdif*}
+% Define the \cs{letdif} and \cs{letdif*} command. The internal version of \cs{letdif}
+% is \cs{@letdif}, of \cs{letdif*} is \cs{s at letdif}.
+% \begin{macrocode}
+\def\@letdif#1#2{\AtBeginDocument{
+% \end{macrocode}
+% |#1| is the final command; |#2| is the ``control sequence name'' of |#1|'s initial definition.
+% Here we create a command (\cs{csname}|#2 at old|\cs{endcsname}) to restore |#2|.
+% \begin{macrocode}
+ \ifcsname #2 at old\endcsname\else
+ \expandafter\let\csname #2 at old\expandafter\endcsname%
+ \csname #2\endcsname
+ \fi
+% \end{macrocode}
+% Finally let |#1| be the new command.
+% \begin{macrocode}
+ \gdef#1{\mathinner{\csname #2 at old\endcsname}\mup at tch}
+}}
+% \end{macrocode}
+% The definition of \cs{s at letdif} is similar, but with the patch for negative skips.
+% \begin{macrocode}
+\def\s at letdif#1#2{\AtBeginDocument{
+ \ifcsname #2 at old\endcsname\else
+ \expandafter\let\csname #2 at old\expandafter\endcsname%
+ \csname #2\endcsname
+ \fi
+ \gdef#1{\mathinner{\s at beforep@tch\csname #2 at old\endcsname\mbox{}}\mup at tch}
+}}
+\def\letdif{\@ifstar\s at letdif\@letdif}
+% \end{macrocode}
+% \DescribeMacro{\newdif}\DescribeMacro{\newdif*}
+% Define the \cs{newdif} and \cs{newdif*} commands. |#1| is the final command; |#2| is the ``long'' argument.
+% \begin{macrocode}
+\long\def\@newdif#1#2{\AtBeginDocument{
+ \ifdefined#1
+ \PackageError{fixdif}{\string#1 is already defined.}
+ {Try another command instead of \string#1.}
