Problem with creating own bibliography style with Bibulous

Question

I need to create this bibliography style with Bibulous.

With the following code I get really close:

TEMPLATES:
book =  [<au>.] [\textit{"<title>"}.] [<address> <year>.]
electronic = [<au>.] [\textit{<institution>.}] [<date>.] ["<title>".] 
[<url>.] 
[<dateofchange>]. [<urldate>.]            
oral = [<author>.] [<interviewer>,] [<date>,] [<address>.]
inbook = [<author>.] ["<articletitle>".] [In: <title>,] hg. v. 
[<publisher>.] [<address>] [<place>.] [<pages>.]
article = [<author>.] ["<title>".] [\textit{<journal>,] [<year>,] 
[<number>,}] [<pages>.]

The optional brackets are intentional because often one argument is missing in the .bib file.

Now I need to sort them alphabetically (as described here:Can bibulous sort references alphabetically? Ask) (first the surename and then the forename, both fully written out) but without the numbers on the left side. It should look like example#9 here. Somehow I'm unable to put the codes together so they work properly.

\documentclass[11pt, a4papter] {scrartcl}
\begin{document}
Lorem ipsum dolor sit amet, \cite{gehalt} consetetur sadipscing elitr, 
\cite{Lenz1}. Lorem ipsum dolor sit amet. \cite{ackeret}
\end{document}

With .bib file

@Electronic{gehalt,
  author      = {Rütti, Nicole},
  institution = {NZZ Online},
  date        = {2017-07-27},
  title       = {Sind Frauen wirklich selber schuld am tieferen Gehalt?},
  url         = {https://www.nzz.ch/wirtschaft/frauen-und-lohnverhandlungen-auf-stoeckelschuhen-rueckwaerts-ueber-ein-minenfeld-laufen-ld.1307984},
  urldate     = {2018-10-14},
}


@Electronic{ackeret,
  author      = {Ackeret, Markus},
  institution = {NZZ Online},
  date        = {2017-05-25},
  title       = {Im Übereifer des politischen Gefechts},
  url         = {https://www.nzz.ch/international/debatte-um-die-bundeswehr-im-uebereifer-des-politischen-gefechts-ld.1296154},
  urldate     = {2018-10-14},
}

@Electronic{Lenz1,
  author      = {Lenz, Christoph},
  institution = {Tages-Anzeiger Online.},
  date        = {2017-07-04},
  title       = {Rechenspiele der Armee haben politische Folgen},
  url         = {https://www.tagesanzeiger.ch/schweiz/standard/rechenspiele-der-armee-haben-politische-folgen/story/19945957},
  urldate     = {2018-10-16},
}

EDIT: After the suggestions from moewe I changed the code slightly:

\documentclass[11pt, a4papter] {scrartcl}
 \renewcommand{\@biblabel}[1]{} \renewcommand{\@cite}[2]{{#1\if@tempswa , 
  #2\fi}} \makeatother
    \begin{document}
    Lorem ipsum dolor sit amet, \cite{gehalt} consetetur sadipscing elitr, 
    \cite{Lenz1}. Lorem ipsum dolor sit amet. \cite{ackeret}
    \end{document}

.bst file

TEMPLATES:
book =  [<au>.] [\textit{"<title>"}.] [<address> <year>.]
electronic = [<au>.] [\textit{<institution>.}] [<date>.] ["<title>".] `[<url>.] [<dateofchange>]. [<urldate>.]`            
oral = [<author>.] [<interviewer>,] [<date>,] [<address>.]
inbook = [<author>.] ["<articletitle>".] [In: <title>,] hg. v. 

[<publisher>.] [<address>] [<place>.] [<pages>.]
    article = [<author>.] ["<title>".] [{\textit<journal>,] [<year>,] [<number>,}] [<pages>.]


SPECIAL-TEMPLATES:
au = <authorname.0>; ...; <authorname.9>

This two changes remove the numbers and show the full name of the author. However, the authors aren't sorted alphabetically and I still don't manage that the surename comes first and then the forename.

If anyone could help me I would be very grateful.

Since Bibulous is a drop-in replacement for BibTeX you can combine it with any citation package that you can use for BibTeX. I suggest you load natbib, because natbib has good support for author-year citations. With natbib run in author-year mode there will be no numbering in the bibliography.

Sorting by author and year is achieved with sortkey.

In the above example I had to give both the year and the date because Bibulous does not parse the date field by default. But it should be possible to write a small Python function that does this automatically....

Here is a .bst that I thought would work even with date, but did not because I could not get Bibulous to resolve variables in the special templates section (see https://github.com/nzhagen/bibulous/issues/15).

TEMPLATES:
book =  [<au>.] [\textit{\enquote{<title>}}.] [<address> <year>.]
electronic = [<au>.] [\textit{<institution>.}] [<date>.] [\enquote{<title>}.] [<url>.] [<dateofchange>.] [<urldate>.]
oral = [<au>.] [<interviewer>,] [<date>,] [<address>.]
inbook = [<au>.] [\enquote{<title>}.] [In: <booktitle>,] hg. v. [<publisher>.] [<address>] [<place>.] [<pages>.]
article = [<au>.] [\enquote{<title>}.] [\textit{<journal>,] [<year>,] [<number>,}] [<pages>.]


SPECIAL-TEMPLATES:
citelabel = <authorlist.0.last>, <dateyear>
sortkey = <authorlist.0.last><dateyear>


OPTIONS:
allow_scripts = True
namelist_format = last_name_first
use_firstname_initials = False


VARIABLES:
dateyear = parse_date_or_year(entry, options)

DEFINITIONS:
def parse_date_or_year(entry, options):
    '''
    Parses the ISO 8601 date in the date field or year in year field
    '''

    if ('date' in entry):
        datematch = re.search(r'\A([0-9]{4})(?:-[0-9]{2}){0,2}(?:/([0-9]{4})(?:-[0-9]{2}){0,2})?\Z', entry['date'])
        if datematch.group(2):
            return(datematch.group(1) + "--" + datematch.group(2))
        elif datematch.group(1):
            return(datematch.group(1))
    elif ('year' in entry):
        return(entry['year'])

    return(None)
