# Move names of editors followed by (Ed./Eds.) and a comma before title in biblatex

Shameless plug: The styles of the biblatex-ext bundle have a slightly more sophisticated version of this implemented as an option. Load ext-<standardstyle>, e.g. ext-authoryear-comp and set the option innamebeforetitle to true.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber,
style=ext-authoryear, innamebeforetitle=true]{biblatex}

\DeclareFieldFormat{editortype}{\mkbibparens{#1}}

\DeclareFieldAlias{translatortype}{editortype}
\DeclareDelimAlias{translatortypedelim}{editortypedelim}

This is really where biblatex is not that flexible.

We can use xpatch to patch the drivers for @inbook, @incollection and @inproceedings

\xpatchbibdriver{inbook}
{\usebibmacro{in:}%
\usebibmacro{bybookauthor}%
\newunit\newblock
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{byeditor+others}}
{\usebibmacro{in:}%
\usebibmacro{bybookauthor}%
\newunit\newblock
\usebibmacro{byeditor:in}%
\newunit\newblock
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{byeditor+others}}
{}{}

\xpatchbibdriver{incollection}
{\usebibmacro{in:}%
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{byeditor+others}}
{\usebibmacro{in:}%
\usebibmacro{byeditor:in}%
\setunit{\labelnamepunct}\newblock
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{byeditor}}
{}{}

\xpatchbibdriver{inproceedings}
{\usebibmacro{in:}%
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{event+venue+date}%
\newunit\newblock
\usebibmacro{byeditor+others}}
{\usebibmacro{in:}%
\usebibmacro{byeditor:in}%
\setunit{\labelnamepunct}\newblock
\usebibmacro{maintitle+booktitle}%
\newunit\newblock
\usebibmacro{event+venue+date}%
\newunit\newblock
\usebibmacro{byeditor+others}}
{}{}


We also redefine byeditor:in

\newbibmacro*{byeditor:in}{%
\ifnameundef{editor}
{}
{\printnames[editorin]{editor}%
\mkbibparens{\usebibmacro{editorstrg}}%
\clearname{editor}%


and a new name format

\DeclareNameAlias{editorin}{first-last}

Guidos way, or - without another package, but with a lot of more code lines - you can change the bibliography-driver for @incollection from standard.bbx, to display the data in your wanted order; change the byeditor+others-macro from biblatex.def to put parencites around the editor data; and change the editorstrg from biblatex.def to use the capitalized version \bibcpstring instead of \bibstring.

Output:

EDIT fixed the issue of multi-volume (with maintitle) and single editor.

A possibility is to abuse the biblatex in: macro to to format and print the information as desired.

\xpatchbibmacro{editorstrg}{\bibstring}{\bibcpstring}{}{}
\xpatchbibmacro{editorstrg}{\bibstring}{\bibcpstring}{}{}

\renewbibmacro*{in:}{
\ifentrytype{incollection}{%
\DeclareNameAlias{editor}{first-last}
\printtext{In}
\ifnameundef{editor}
{}
{\printnames{editor}%
\mkbibparens{\usebibmacro{editorstrg}}
}%
\usebibmacro{maintitle+booktitle}
\clearfield{maintitle}
\clearfield{booktitle}
\clearfield{volume}
\clearfield{part}
\clearname{editor}
}
{}%
}


In this case the "simple" in: contains the directives to print the editors and the book title.

The tricks are: (1) use a guard, \ifentrytype{incollection}, to restrict the modification to the specific entrytype; (2) delete the content of the fields booktitle and editor, thus they are no longer a available in the rest of directive in the driver for incollection, and (3) define a new directive to switch last name and first name for the editors: this can be specifying that editor is an "alias" for the predefined name format first-last, i.e., \DeclareNameAlias{editor}{first-last}.

Notice that the excellent and convenient xpatch package (i.e., include \usepackage{xpatch}) is used to modify how the biblatex string editor(s) is printed. Notice that we need to patch it twice one: the first for the plural version, and the second for the singular case (only one editor).

Here is the outcome:
