How to not use the full fist name in IEEE spconf paper (abbreviated first name with bibtex)

I'm trying to put the first name of the authors in the references, abbreviated. For example John Smith should become J. Smith. I was able to produce the problem even from official MLSP conference template. Here is the minimal example:

\documentclass{article}
\usepackage{mlspconf}

\title{How abbriviated first name appear in the references}
\name{John Doe}

\begin{document}

\maketitle
\begin{abstract}
The problem is apearing of full first name in the references
\end{abstract}
\begin{keywords}
test first name
\end{keywords}

\section{Introduction}

This is a test \cite{Schr}.

\bibliographystyle{IEEEbib}
\bibliography{refs}

\end{document}


and here is the .bib tex:

@article{Schr,
author = {Smith, John and Doe, George},
title = {Test name abbriviations},
journal = {Commun. ACM},
issue_date = {May 2018},
volume = {65},
number = {4},
month = apr,
year = {2018},
issn = {0002-1834},
pages = {60--69},
numpages = {11},
publisher = {ACM},
address = {New York, NY, USA},
}


NOTE1: I'm using bibtex and just in case, the IEEEbib.bst and mlspconf.sty are available at here

Thanks for providing a link to the bst file. I suggest you proceed as follows.

• Make a copy of the file IEEEbib.bst and call the copy, say IEEEbib-abbrev.bst. (Don't edit an original file directly.)

• Open the file IEEEbib-abbrev.bst in a text editor. (The editor you use for your tex files will do fine.)

• In the file IEEEbib-abbrev.bst, locate the function format.names and, in this function, the line

    { s nameptr "{ff~}{vv~}{ll}{, jj}" format.name$'t :=  Change {ff~} to {f. }. • Next, locate the function format.crossref.editor and, in this function, the line  { editor #2 "{ff }{vv }{ll}{ jj}" format.name$ "others" =


Change {ff } to {f. }.

In case you haven't already guessed what's going on: ff is short for "full first name", and f. is short for "first name abbreviated to first initial, followed by a dot (period, full stop)".

• Save the file IEEEbib-abbrev.bst, either in the directory where the main tex file is located or in a directory that's searched by BibTeX. If you choose the latter option, be sure to update the filename database of your TeX distribution suitably.

• In your main tex file, change the instruction

\bibliographystyle{IEEEbib}


to

\bibliographystyle{IEEEbib-abbrev}


and perform a complete recompile cycle -- LaTeX, BibTeX, and LaTeX twice more -- to fully propagate all changes.

Happy BibTeXing!
