Changing \autocite format to include page number

Question

absolute Latex beginner here with a question: I changed the \autocite command to add in-text citation in the following format: (Author year: [page number]) (for example: (Dylan 1967: 5)). I used the following code in main.tex:

\DeclareCiteCommand{\autocite}
  {\usebibmacro{prenote}}
  {\printtext[parens]{\printnames{labelname} \printfield{year}\addcolon\addspace\usebibmacro{postnote}}}
  {\multicitedelim}

Here's the issue. After each citation (they do work miraculously) Latex does a line break which I do not want. Is there either a way to get rid of the line break or a smarter way in general to achieve my desired in-text citation?

Thank you!

Since its not fully clear which biblatex style you're using, here is a simple solution for style=authoryear. But it may also work with other styles, depending on the definition of some macros.

Here a full working MWE with updated code:

\documentclass{article}

\begin{filecontents*}[overwrite]{bibfile.bib}
  @article{bouche_2006,
  author    = {Bouche, Thierry},
  journal   = {Tugboat},
  title     = {A {pdfLaTeX}-based automated journal production system},
  year      = {2006},
  number    = {1},
  pages     = {45--50},
  volume    = {27},
}
\end{filecontents*}

\usepackage[style=authoryear]{biblatex}
\addbibresource{bibfile.bib}

% code snippet for you to copy:
\DeclareDelimFormat{postnotedelim}{\addcolon\space}
\DeclareFieldFormat{postnote}{#1}
\DeclareCiteCommand{\autocite}[\mkbibparens]
  {\usebibmacro{prenote}}
  {\printnames{labelname}\space\printfield{year}}
  {\multicitedelim}
  {\usebibmacro{postnote}}
% end snippet

\begin{document}
test \autocite[227]{bouche_2006}. test

\printbibliography
\end{document}

As you can see, there is no linebreak after the citation. If it still occurs in your document when you use my adapted snippet, we need additional informations about your code.

If you still want the page prefix p. in front of the given pagenumber, just uncomment the DeclareFieldFormat line.
