global page number in report

Question

Some complexity is encountered if one wants to override the setting not to add page number in abstract in a report.

I introduce page numbering in abstract according to Include Page Number in Abstract

However, I need to introduce manually \addtocounter{page}{} in order to align page numbers in different parts of the report as illustrated in this example:

\documentclass{report}
\title{some title}
\usepackage{lipsum}
\begin{document}
\setcounter{page}{2}
some introduction
\begin{abstract}
\addtocounter{page}{2}
  \thispagestyle{plain}
  \lipsum[1]
\end{abstract}
\addtocounter{page}{3}
\lipsum[2]
\end{document}

Is there a way to enforce different parts in a report to inherit page count from the previous section?

Answer 1

Use a better class:

\documentclass[abstract=on]{scrreprt}

\title{some title}
\usepackage{lipsum}
\begin{document}
\setcounter{page}{2}
some introduction

\begin{abstract}
\thispagestyle{plain}
\lipsum[1]
\end{abstract}
\lipsum[2]
\end{document}

Answer 2

For unclear to me reasons, report encloses abstract in a titlepage environment.

Just patch it to not do it.

\documentclass{report}
\usepackage{etoolbox}

\usepackage{lipsum}

\patchcmd{\abstract}{\titlepage}{\cleardoublepage}{}{}
\patchcmd{\endabstract}{\endtitlepage}{\clearpage}{}{}

\begin{document}

\title{some title}

some introduction

\begin{abstract}
  \lipsum[1]
\end{abstract}

\lipsum[2]

\end{document}

The console output shows the page numbering is continuous.
