OK, another one of those "hey, the bib module has an issue"-kind of
mails. The problem is that \bibdoif and its relatives don't work.
They always evaluate to true. I have tried to figure out why this is
so, but I'm just not good enough at reading TeX macros (yet). The main
problem is that I want to do something like this for my
\setuppublicationlist:
\doglobal\newif\ifBIBLoutputbeforesurname
\global\BIBLoutputbeforesurnamefalse
\def\BIBLwholename#1#2#3#4#5%
{\bibdoif{#1}{#1\unskip\bibalternative\c!firstnamesep\BIBLoutputbeforesurnametrue}%
\bibdoif{#4}{#4\unskip\bibalternative\c!firstnamesep\BIBLoutputbeforesurnametrue}%
\bibdoif{#2}{#2\unskip\bibalternative\c!vonsep\BIBLoutputbeforesurnametrue}%
\ifBIBLoutputbeforesurname \else
\unskip%
\BIBLoutputbeforesurnamefalse%
\fi
#3\bibalternative\c!surnamesep%
\bibdoif{#5}{#5\unskip}}
The problem is that one can't have
\author[]{}[]{}{Organization}
without extra spaces appearing before the Organization. Another issue is that
extra spaces occur between the first and last name in the \normalauthor
style,

Nikolai,
I too discovered that \bibdoif always evaluates to true. For some reason
(which I don't know), \ifx does not take a an empty group {} and evaluate it
to \empty. So, I came up with the following ...
\def\bibdoiftext#1#2%
{{\setbox0=\hbox{#1}\ifdim\wd0>0pt{#2}\fi}}
Basically, I place the contents of #1 into an \hbox, then check to see if
it's width > 0. If yes (meaning #1 is not empty), then typeset #2. I'm not
sure if I need the double group {{}}, since box0 is being assigned, I don't
want to overwrite its prior contents, if any. Comments anyone?? I'm still
learning TeX macro programming ...
I also redefined some of the author formats for my own uses ... and indeed,
it works!!
\def\normalshortauthor#1#2#3#4#5%
{\bibdoiftext{#4}{#4~}\bibdoiftext{#2}{#2~}#3\bibdoiftext{#5}{~#5}}
\def\invertedshortauthor#1#2#3#4#5%
{\bibdoiftext{#2}{#2~}#3\bibdoiftext{#5}{~#5}\bibdoiftext{#4}{,~#4}}
You will notice that in both cases, the last name (#3) is always typeset, so
optional items before it have a trailing space, while optional items after
it have a leading space. This ensures there are no extra spaces either
before or after the author, regardless of which portions are included. I
used ~ for spacing to ensure that a name is not split between its components
and to provide consistent spacing after the periods.
