Text Formatting ⇒ prefix in front of section numbers

[gert]

Dear Latex Gurus,

Is it possible to put a prefix in front of section numbers?

Code: Select all

\documentclass[12pt]{amsart}

\begin{document}

\section{Article General Remarks}
\subsection{sub 1. Additional notes}

\end{document}

Should look like:

Article 1. General Remarks
Article 1.1 Additional notes

Thanks for any reply,
Gert

ps
I searched for "prefix section numbering" and other terms like this but couldn't find an answer.

Hi,

perhaps something like the following is what you are trying to achieve?

Code: Select all

\documentclass[12pt]{amsart}

\makeatletter
\def\@startsection#1#2#3#4#5#6{%
 \if@noskipsec \leavevmode \fi
 \par \@tempskipa #4\relax
 \@afterindenttrue
 \ifdim \@tempskipa <\z@ \@tempskipa -\@tempskipa \@afterindentfalse\fi
 \if@nobreak \everypar{}\else
     \addpenalty\@secpenalty\addvspace\@tempskipa\fi
 \@ifstar{\@dblarg{\@sect{#1}{\@m}{#3}{#4}{#5}{#6}}}%
         {\@dblarg{\@sect{#1}{#2}{#3}{#4}{#5}{Article #6}}}%
}
\makeatother

\begin{document}

\section{General Remarks}
\subsection{Additional notes}

\end{document}

it certainly does what I'm trying to achieve.
Thank you very much, amazing.

Would it be possible to have the sections, subsections all left aligned. With the set-up as given the sections are centered. I've been trying to work on the code but haven't been successful.

Thanks,
Gert

You're welcome. Regarding the new issue, an answer was given in this other thread.
