[Tex/LaTex] Combining \autoref and \eqref

cross-referencinghyperref

Say the equation is

\begin{equation}
r^2 = x^2 + y^2 \text{.} \label{eq:circ}
\end{equation}

Now, if I use

\autoref{eq:circ}

I get Equation 1. How do I get Equation (1) (the parenthesis that we get while using \eqref) while still maintaining the hyperlink?

Edited in response to an answer below.

I have defined two versions of the command to be used at the beginning and in the middle of a sentence:

\def\chapterautorefname{Chap.}
\def\sectionautorefname{Sec.}
\def\subsectionautorefname{sub--Sec.}
\def\figureautorefname{Fig.}
\def\tableautorefname{Tab.}
\def\equationautorefname{Eq.}

\newcommand{\Autoref}[1]{%
  \begingroup%
  \def\chapterautorefname{Chapter}%
  \def\sectionautorefname{Section}%
  \def\subsectionautorefname{Sub--Section}%
  \def\figureautorefname{Figure}%
  \def\tableautorefname{Table}%
  \def\equationautorefname~#1{Equation~(#1)}%
  \autoref{#1}%
  \endgroup%
}

While using \Autoref it says

Use of \equationautorefname doesn't match its definition \Autoref{eq:llg1}.

How do I fix it?

I found this trick in an old document of mine, but I have a feeling that the idea comes from someone else:

\documentclass{article}

\usepackage{hyperref}

\def\equationautorefname~#1\null{Equation~(#1)\null}

\begin{document}

\begin{equation}
  \label{eq:circ}
  r^2 = x^2 + y^2.
\end{equation}
\autoref{eq:circ}

\end{document}

[Tex/LaTex] Multiple references with \autoref

EDIT added a way to set the plural names, which in effect gives foreign language support

I decided that I needed this feature of \autoref today and then I was surprised that I was unable to find it...so here is one way to define an \Autoref command that will do it. Specifically,

\Autoref{ref1,ref2,...}

will expand into the plural of the first reference followed by hyperlinks for all of the references. Here's the sample output from the MWE below:

$Sample for multiple <code>\autoref</code>'s$

There are a few minor(?) limitations in that the macro assumes that:

all of the references are of the same "type" (so all lemmas, or all theorems etc)
doesn't handle the optional argument to \autoref or the *-form (would be easy to fix...)
it probably does not play well with equation references
by default the plural form is obtained simply by adding an s to the "singular" name (so it is English centric). This can be overridden by defining a plural version of the autorefname, for example \providecommand*{\lemmaautorefnameplural}{Lots of lemmas}. A more realistic application would be to define plurals for other languages. The ...autorefnameplural form is optional

The \Autoref macro behaves like \autoref when it is given one reference.

Anyway, here's the code:

\documentclass[a4paper]{amsart}
\usepackage[colorlinks=true]{hyperref}
\makeatletter

% define a macro \Autoref to allow multiple references to be passed to \autoref
\newcommand\Autoref[1]{\@first@ref#1,@}
\def\@throw@dot#1.#2@{#1}% discard everything after the dot
\def\@set@refname#1{%    % set \@refname to autoefname+s using \getrefbykeydefault
    \edef\@tmp{\getrefbykeydefault{#1}{anchor}{}}%
    \xdef\@tmp{\expandafter\@throw@dot\@tmp.@}%
    \ltx@IfUndefined{\@tmp autorefnameplural}%
         {\def\@refname{\@nameuse{\@tmp autorefname}s}}%
         {\def\@refname{\@nameuse{\@tmp autorefnameplural}}}%
}
\def\@first@ref#1,#2{%
  \ifx#2@\autoref{#1}\let\@nextref\@gobble% only one ref, revert to normal \autoref
  \else%
    \@set@refname{#1}%  set \@refname to autoref name
    \@refname~\ref{#1}% add autoefname and first reference
    \let\@nextref\@next@ref% push processing to \@next@ref
  \fi%
  \@nextref#2%
}
\def\@next@ref#1,#2{%
   \ifx#2@ and~\ref{#1}\let\@nextref\@gobble% at end: print and+\ref and stop
   \else, \ref{#1}% print  ,+\ref and continue
   \fi%
   \@nextref#2%
}

\makeatother
\newtheorem{lemma}{Lemma}
\providecommand*{\lemmaautorefname}{Lemma}
%\providecommand*{\lemmaautorefnameplural}{Lots of lemmas}
\parindent=0pt
\begin{document}

\begin{lemma}1+1=2\label{one}\end{lemma}
\begin{lemma}2+2=4\label{two}\end{lemma}
\begin{lemma}3+3=6\label{three}\end{lemma}

By \autoref{one}, \autoref{two} and \autoref{three} we are amazed.

By \Autoref{one} we are not amazed.

By \Autoref{one,two} we are a little amazed.

By \Autoref{one,two,three} we are quite amazed.

\end{document}

If you uncomment the line

\providecommand*{\lemmaautorefnameplural}{Lots of lemmas}

then the output is:

A more realistic use of this feature would be to add foreign language support.

[Tex/LaTex] Parenthesis while using subfig and autoref

You could use \renewcommand\thesubfigure{(\alph{subfigure})}, as shown below.

\documentclass{article}

% subfig setup
\usepackage[labelformat=simple]{subfig}
\renewcommand\thesubfigure{(\alph{subfigure})}
\newcommand{\subfigureautorefname}{\figureautorefname}

\usepackage{hyperref}

\begin{document}

\begin{figure}
 \subfloat[]{
 \centering
 \rule{30pt}{20pt}
 \label{fig:firstpic}
 }
 \hfill
 \subfloat[]{
 \centering
 \rule{30pt}{20pt}
 \label{fig:secondpic}
 }
 \caption{}
\end{figure}

\autoref{fig:firstpic} and \autoref{fig:secondpic}

\end{document}

enter image description here

Note that \autoref is from the \hyperref package.
