Hyperlink in DOI in IEEEtran Bibliography

Question

Previously, including a DOI in a IEEEtran-styled bibliography has been discussed on TexExchange under the title DOI in IEEEtran bibliography and a solution has been provided in form of a patch [1]. However, the solution does not feature a hyperlink for the DOI. One of the particular benefits of using a DOI is the universal and unique URL that links to the respective archive: http://dx.doi.org/ + «DOI»

How can I make the DOI "clickable", i.e. provide a seamless (hyperref) hyperlink that will open a webbrowser when I click on the DOI?

Answer 1

The patch provides a function for inserting the DOI:

%% DOI

FUNCTION {format.doi}
{ doi empty$
    { "" }
    { this.to.prev.status
      this.status.std
      cap.yes 'status.cap :=
      name.doi.prefix " " *
      "\doi{" * doi * "}" *
      punct.no 'this.status.punct :=
      punct.period 'prev.status.punct :=
      space.normal 'this.status.space :=
      space.normal 'prev.status.space :=
      quote.no 'this.status.quote :=
    }
  if$
}

Replace the line which inserts the DOI

"\doi{" * doi * "}" *

by

"\href{http://dx.doi.org/\doi{" * doi * "}}{\doi{" * doi * "}}" *

to yield the augmented DOI that includes a hyperlink.

That is, the function is replaced with the code %% DOI

FUNCTION {format.doi}
{ doi empty$
    { "" }
    { this.to.prev.status
      this.status.std
      cap.yes 'status.cap :=
      name.doi.prefix " " *
      "\href{http://dx.doi.org/\doi{" * doi * "}}{\doi{" * doi * "}}" *
      punct.no 'this.status.punct :=
      punct.period 'prev.status.punct :=
      space.normal 'this.status.space :=
      space.normal 'prev.status.space :=
      quote.no 'this.status.quote :=
    }
  if$
}

Answer 2

Recently. I got the helpful hints thanks to the ticket #394811. However, I had to modify the existing statements to append a DOI (Digital Object Identifier) in the reference section of the T-CE journal (Transactions on Consumer Electronics). So, I modified the below statements as follows.

  name.doi.prefix ", " *
  "doi: \href{http://dx.doi.org/" * doi * "}{\doi{" * doi * "}}" *
  name.doi.postfix ". " *

The content of the " FUNCTION {format.doi}" is as folows.

%% DOI
%% added by GQMJr
%% Modified by Geunsik Lim on Apr-05-2020 for T-CE.
FUNCTION {format.doi}
{ doi empty$
    { "" }
    { this.to.prev.status
      this.status.std
      cap.yes 'status.cap :=
      name.doi.prefix ", " *
      "doi: \href{http://dx.doi.org/" * doi * "}{\doi{" * doi * "}}" *
      name.doi.postfix ". " *
      punct.no 'this.status.punct :=
      punct.period 'prev.status.punct :=
      space.normal 'this.status.space :=
      space.normal 'prev.status.space :=
      quote.no 'this.status.quote :=
    }
  if$
}

And then, The DOI is successfully generated. :)

I had to modify this a bit more to get it to work for me:

%% DOI
%% added by GQMJr
%% Modified by Geunsik Lim on Apr-05-2020 for T-CE.
%% Modified again by Calvin Love on Dec-15-2021
FUNCTION {format.doi}
{ doi empty$
{ "" }
{ this.to.prev.status
this.status.std
cap.yes 'status.cap :=
name.doi.prefix ", " *
"doi: \href{http://dx.doi.org/" * doi * "}{" * doi * "}" *
name.doi.postfix ". " *
punct.no 'this.status.punct :=
punct.period 'prev.status.punct :=
space.normal 'this.status.space :=
space.normal 'prev.status.space :=
quote.no 'this.status.quote :=
}
if$
}
