How to write a definition with variants?
7
In TeX I can define, say
def1#1 is #2.{#1 & is & #2.\}
and
def2#1 has #2.{#1 & has & #2.\}
with an easy usage:
1 Jim Jones is a fictional character.
and
2 Tim Smith has two brothers.
This gives three columns of a tabular: Jim Jones, is, a fictional character. Similarly in the second case.
Can I write a definition depending on, in this case, is/has so I can write
3 Jim Jones is a fictional character.
and
3 Tim Smith has two brothers.
obtaing the previous results?
Solutions using Lua or expl3 are OK, but I hope that a pure TeX one is also possible.

At the TeX level for anydefyou can have only one parameter text (the#1 is #2.and#1 has #2.in your1and2respectively).

A listofitems approach. Also, listofitems is available in Plain TeX.
documentclass{article}
usepackage{listofitems}
defvariant#1.{%
setsepchar{is||has}%
greadlist*varinput{#1}
varinput[1] & varinputsep[1] & varinput[2].
}
begin{document}
begin{tabular}{|c|c|c|}
variant Jim Jones is a fictional character.\
variant Tim Smith has two brothers.
end{tabular}
end{document}
Similarly done in plain TeX
input listofitems
defvariant#1.{%
setsepchar{is||has}%
greadlist*varinput{#1}
varinput[1] & varinputsep[1] & varinput[2].
}
