Chapter displayed in headings and page number on the left

Question

I am writing my thesis using the class memoir. I have two problems to get nice headings/footers. First, I want the page number to be in the footer, on the right or on the left but for the first page of a chapter, it stays centered. Then, for pages with an even number, I want the name of the current chapter to be inserted in the headings. I can not find how to do these things. Here is my code:

\documentclass[12pt]{memoir}

\usepackage{blindtext}
\usepackage[english]{babel}
\nouppercaseheads
\makepagestyle{these}
\makeevenhead{these}{\rightmark}{}{}
\makeoddhead{these}{}{}{\leftmark}
\makeheadrule{these}{\textwidth}{\normalrulethickness}
\makeevenfoot{these}{\thepage}{}{}
\makeoddfoot{these}{}{}{\thepage}
\makepsmarks{these}{%
\createmark{section}{left}{shownumber}{}{\ } 
\createmark{chapter}{right}{shownumber}{}{\ }
\createplainmark{toc}{both}{\contentsname}}
\pagestyle{these}

\makeatother

Answer 1

Surely there must be a question on this site, which already give the answer to this, but you could do something like:

\documentclass[
a4paper, % Stock and paper size.
11pt, % Type size.
% article,
% oneside, 
onecolumn, % Only one column of text on a page.
% openright, % Each chapter will start on a recto page.
% openleft, % Each chapter will start on a verso page.
openany, % A chapter may start on either a recto or verso page.
]{memoir}

\usepackage{lipsum} % Will come in handy below...

%%% HEADER AND FOOTER

\makepagestyle{standard} % Make standard pagestyle

\makeatletter                 % Define standard pagestyle
\makeevenfoot{standard}{}{}{\thepage} % Even footer
\makeoddfoot{standard}{\thepage}{}{}  % Odd Footer
\makeevenhead{standard}{}{\leftmark}{} % ...
\makeoddhead{standard}{}{\leftmark}{}  %
% \makeheadrule{standard}{\textwidth}{\normalrulethickness}
\makeatother                  %

\makeatletter % Make marks (to put chapter title etc. in the header)
\makepsmarks{standard}{
\createmark{chapter}{both}{shownumber}{\@chapapp\ }{ \quad }
\createmark{section}{right}{shownumber}{}{ \quad }
\createplainmark{toc}{both}{\contentsname}
\createplainmark{lof}{both}{\listfigurename}
\createplainmark{lot}{both}{\listtablename}
\createplainmark{bib}{both}{\bibname}
\createplainmark{index}{both}{\indexname}
\createplainmark{glossary}{both}{\glossaryname}
}
\makeatother   

\makepagestyle{chap} % Make new chapter pagestyle

\makeevenfoot{chap}{}{\thepage}{} % Define new chapter pagestyle
\makeoddfoot{chap}{}{\thepage}{}  %

\nouppercaseheads

I'm not sure that this is exactly what you desire. If not, I hope the code is clear enough for you to make the changes yourself.
