cleveref refers to a theorem as a definition when theorems and definitions share a counter

Question

The following LaTeX document is saved in a file whose path is ~/test.tex.

\documentclass{article}

\usepackage{amsthm}
\newtheorem{definition}{Definition}
\newtheorem{theorem}[definition]{Theorem}

\usepackage{cleveref}

\begin{document}
\begin{definition}\label{d}
This is a definition.
\end{definition}

\begin{theorem}\label{t}
This is a theorem.
\end{theorem}

Here is a reference to~\cref{t}.
\end{document}

When the following commands are executed at the terminal:

> cd ~
> pdflatex test
> pdflatex test

a PDF file is generated at the path ~/test.pdf. When opened in a PDF viewer, the file displays as follows:

Notice that the reference to the theorem is displayed as a reference to a definition.

How can I get \cref to distinguish between the theorem and the definition, while maintaining a continuous, unified numbering schema for theorems definitions?

Answer 1

This works:

\documentclass{article}

\usepackage{thmtools}

\declaretheorem[name=Definition]{definition}
\declaretheorem[name=Theorem, numberlike=definition]{theorem}
\usepackage{cleveref}
\crefname{theorem}{Theorem}{Theorems}
\crefname{definition}{Definition}{Definitions}

\begin{document}

\begin{definition}\label{d}
This is a definition.
\end{definition}

\begin{theorem}\label{t}
This is a theorem.
\end{theorem}

Here is a reference to~\cref{t} based upon \cref{d}.

\end{document}
