I would like to automatically boldface a single author's entries in a bibliography generated with natbib. The bio.tex file looks like this (everything has been fictionalized):

documentclass{bio}



updatebio{%

    name={Bob Digital},

    title={Prof.},

    dept={Department of Antics},

    uni={University of Fable},

    email={bob.dole@uof.edu},

    tel={(123) 456-7890},

    web={https://uof.edu/bobdigital}

}



begin{document}



    Products



end{document}

The Products command is the main command of interest, which automatically generates the bibliography from a BibTeX file. The bio.cls file looks like this:

NeedsTeXFormat{LaTeX2e}

And last, an example references.bib file:

@article{Digital1968,

  author = {Bob Digital and Mister Roboto},

  doi = {https://doi.org/10.1016/0022-5193(68)90079-9},

  issn = {0022-5193},

  journal = {Journal of Theoretical Theory},

  number = {3},

  pages = {280--299},

  title = {{Some test title to use here just for fun}},

  url = {http://www.sciencedirect.com/science/article/pii/0022519368900799},

  volume = {18},

  year = {1968}

}



@article{Roboto1948,

  author = {Mister Roboto and Bob Digital},

  doi = {https://doi.org/10.1016/0022-5193(68)90079-9},

  issn = {002-52323},

  journal = {Utopiae},

  number = {2},

  pages = {1--19},

  title = {{Another title to use here just for fun!}},

  url = {http://www.sciencedirect.com/science/article/pii/0022519368900799},

  volume = {1},

  year = {1948}

}

I created a custom bio.bst file, which is too large to share here. The important thing to know is that it uses the AGU format, where the first author is shown as LASTNAME, FI. MI. and subsequent authors are shown as FI. MI. LASTNAME followed by a comma for additional names, where FI == First Initial and MI == Middle Initial. Here is a corresponding .bbl file:

begin{thebibliography}{10}



bibitem{Digital1968}

Digital, B. and M.~Roboto.

newblock {Some test title to use here just for fun}.

newblock emph{Journal of Theoretical Theory}, 18(3):280--299, 1968.

newblock ISSN 022-5193

newblock doi{https://doi.org/10.1016/0022-5193(68)90079-9}.



bibitem{Roboto1948}

Roboto, M. and B.~Digital.

newblock {Another title to use here just for fun!}.

newblock emph{Utopiae}, 1(2):1--19, 1948.

newblock ISSN 002-5232.

newblock doi{https://doi.org/10.1016/0022-5193(68)90079-9}.



end{thebibliography}

In this test example, I would expect Digital, B. and B. Digital to be boldface, regardless of their position in the author list. The issue that I'm having is that citations of the form FI. MI. LASTNAME are not made boldface. I believe this may be due to the format of the spacing...?

You can immediately see from the .bbl file that ~ is used, which is not the same as a space.

Just change the definition of name_makebold:n to

cs_new_protected:Nn name_makebold:n

 {

  tl_set:Nn l__name_input_tl { #1 }

  % full name

  regex_replace_all:nnN

   {

    (

     u{l_name_first_tl} (s|~) u{l_name_last_tl}    % name surname

     |

     u{l_name_initials_tl} (s|~) u{l_name_last_tl} % initials surname

     |

     u{l_name_last_tl} , (s|~) u{l_name_first_tl}       % surname, name

     |

     u{l_name_last_tl} , (s|~) u{l_name_initials_tl}    % surname, initials

    )

   }

   { c{textbf} cB{ 1 cE} }

   l__name_input_tl

  % print

  tl_use:N l__name_input_tl

 }

Remove noexpandarg that doesn't make sense (it is an xstring command).
