How to remove parentheses from single cref references?

Question

I am using cleveref to cross-reference everything. Sometimes I write the reference inline like eq.(1). That is fine. But when it is enclosed in parenthesis it turns out like (eq.(2)). Which is not so nice.

Is it possible to somehow toggle the use of parenthesis in cleveref?

Here's an MWE:


\documentclass{article}
\usepackage{cleveref}
\begin{document}
 \begin{equation}\label{one}
 12+2=34
 \end{equation}
 \begin{equation}\label{two}
 1+2=4
 \end{equation}
 if \cref{one} is correct than (\cref{two})!
\end{document}

Please add an example document showing exactly how are you obtaining those references. — Gonzalo Medina, Aug 27 '15 at 18:55

Declare a “variable” format:

\documentclass{article}
\usepackage{amsmath}
\usepackage{cleveref}

\crefformat{equation}{\eqA eq.~\eqB #2#1#3)}
\newcommand{\eqA}{}
\newcommand{\eqB}{(}
\DeclareRobustCommand{\pcref}[1]{%
  \begingroup
  \renewcommand{\eqA}{(}\renewcommand{\eqB}{}%
  \cref{#1}%
  \endgroup
}

\begin{document}

\begin{equation}
1+1=2 \label{true}
\end{equation}

Here's \cref{true}.

That's all \pcref{true}.

Again \cref{true}

\end{document}

Thankyou. Now I just have to go do this for all of my section, chapter, table, figure references as well :P – niclas ericsson Aug 27 '15 at 20:04
Is it possible to make this take an optional argument, if I would like to add something like (figure 13a)? I mean adding the a manually without using subcaptions, if the letter is hardcoded in the figure. My TeX skills are unfortunately not up to par here – niclas ericsson Aug 27 '15 at 20:24
@niclasericsson Sorry, but this site doesn't work like this. Please, open a new question and specify what precisely you'd like to get. – egreg Aug 27 '15 at 20:27

Here's a slightly modified version of egreg's answer. This works for multiple references and also for all kinds of references.

\documentclass[11pt]{article}
\usepackage[colorlinks]{hyperref}
\usepackage[nameinlink]{cleveref}
\newcommand{\eqlabelleft}{(}
\newcommand{\eqlabelright}{)}
\newcommand{\pcref}[1]{%
\begingroup%
\renewcommand{\eqlabelleft}{}%
\renewcommand{\eqlabelright}{}%
(\cref{#1})%
\endgroup%
}
\creflabelformat{equation}{\eqlabelleft#2#1#3\eqlabelright}
\begin{document}
\begin{equation}
    y = mx + c
    \label{eq:1}
\end{equation}
\begin{equation}
    x^2 + y^2 = 1
    \label{eq:2}
\end{equation}
\cref{eq:1,eq:2}\
\pcref{eq:1,eq:2}\
\cref{eq:1,eq:2}
\end{document}
