General ⇒ Name Seperator (IF conditon for \def)

[SathishV]

Hi Forum,

I am new to Latex, just a Beginner, Basically a perl developer,

I have created a latex file

Code: Select all

Code, edit and compile here:

\begin{document}
\cont{\iname{\isurname{Name1}\ifname{K. C. G.}}\iname{\isurname{Name11}\ifname{Y. Q.}}\iname{\isurname{Name111}\ifname{C.-Z.}}\ititles{Some title Text}\ipage{995}}
\end{document}

Now my need is to define the latex commands, and the display should come as the below

Name1 K. C. G., Name11 Y. Q. and Name111 C.-Z. Some title Text - 995.

\iname - Person Name will repeat several times
\isurname - Surname of a person
\ifname - First Name of a person

\iname will repeat any number of times, say 1 to ...

If only one \iname found inside \cont, display should be like the below
Name1 K. C. G. Some title Text - 995.

If only two \iname found inside \cont, display should be like the below
Name1 K. C. G. and Name11 Y. Q. Some title Text - 995.

If more than two \iname found inside \cont, display should be like the below (and should come after last \iname)
Name1 K. C. G., Name11 Y. Q. and Name111 C.-Z. Some title Text - 995.


I can able to define for \iname seperated by comma, but i don't know how to write a macro to define \iname with different outputs based on the if condition,

Is it possible to define that, i am totally a beginner for latex, please guide me

Thanks & Regards
Sathish V.

I have a feeling you're trying to reinvent the wheel, namely a bibliography. There already are many powerful solutions for this. Nevertheless, for the fun of it here is one possibility. I tried to add comments that hopefully explain what the code does:

% add name to internal list and print list of no further name follows:

% counters for comparison:
\newcounter{@iname@total}
\newcounter{@iname@step}
% print the list:
