# Changing parenthesis of biblatex-apa (mimic 2017 acmart) [duplicate]

I would like to closely mimic the new 2017 ACM citation style (\citestyle{acmauthoryear} and \bibliographystyle{ACM-Reference-Format}). As far as I know, there is no style in biblatex that adapts it (any other suggestions to make this style work without \documentclass{acmart} appreciated).

I am quite happy with biblatex-apa, but I would like to change the parenthesis of \parencite and \textcite from ( to [.

\parencite now: (Doe & Nakamoto, 2017); wanted: [Doe & Nakamoto, 2017]

\textcite now: Doe and Nakamoto (2017); wanted: Doe and Nakamoto [2017]

MWE:

\documentclass{book}

\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\begin{filecontents}{mybib.bib}

@inproceedings{John,
author = {Doe, John and Nakamoto, Satoshi},
title = {Some title},
year = {2017},
}

\end{filecontents}


• Note that biblatex-apa is a very specific style that tries to implement all the requirements of the APA manual of style. If you want to implement a different style it is usually better to start from one of the standard styles and modify those instead of taking an already heavily modified and specialised style such as biblatex-apa or biblatex-chicago. – moewe Jul 26 '18 at 13:17
• Thanks for that tip. Nonetheless, I am already quite happy with biblatex-apa, basically only the parenthesis are a dealbreaker. – A1m Jul 26 '18 at 13:20
• If you plan to publish with the ACM you should probably forget about biblatex. Very few publishers (if any) accept biblatex submissions (see tex.stackexchange.com/q/12175/35864). The acmguide states: "You can disable loading of natbib using the option natbib=false in \documentclass. However, it is not recommended, as well as the use of BibTeX styles other than ACM-Reference-Format.bst, and may delay the processing of the manuscript." – moewe Jul 26 '18 at 13:22
• I am not publishing to ACM, I just like the style. I tried using natbib with ACM-Reference-Format.bst, but unless I did something wrong it didn't really looked as intended without actually using \citestyle{acmauthoryear} which is only available with \documentclass{acmart}. Correct me if I am wrong. – A1m Jul 26 '18 at 13:25
• If you insist on biblatex-apa maybe tex.stackexchange.com/q/16765/35864 can help you. \begin{ad}If you wanted to switch my biblatex-ext styles (those styles are slight extensions of the standard styles that aim to be as customisable as the standard styles while offering a few more options), you could look into \DeclareInnerCiteDelims and \DeclareOuterCiteDelims.\end{ad} – moewe Jul 26 '18 at 13:26
