An old man lived in the village. He was one of the most unfortunate people in the world. The whole village was tired of him; he was always gloomy, he constantly complained and was always in a bad mood. The longer he lived, the more bile he was becoming and the more poisonous were his words. People avoided him, because his misfortune became contagious. It was even unnatural and insulting to be happy next to him. He created the feeling of unhappiness in others.

But it does not give expected output.

Wrong output is generated in Page.txt as shown below

\unhbox \voidb@x \copy \LastWordBox \relax -1
\unhbox \voidb@x \copy \LastWordBox \relax -1

\unhbox \voidb@x \copy \LastWordBox \relax -1
\unhbox \voidb@x \copy \LastWordBox \relax -1
\unhbox \voidb@x \copy \LastWordBox \relax -1

Expected output in Page.txt is below.

Becuase(LastWordofthePage)-1
most(LastWordofthePage)-2
village(LastWordofthePage)-3

Anybody could guide me to get expected output.

Answer 1

A box is a box, not a word. If you use \showbox e.g. like this:

\documentclass{article}
\usepackage[a6paper,footskip=0pt]{geometry}
\usepackage{lastpage,everypage}
\usepackage{fwlw}

\showboxbreadth10
\showboxdepth10
\newcounter{xpage}
\AddEverypageHook{%
 \showbox\LastWordBox}%

\usepackage{lipsum}
\begin{document}
\lipsum[1-3]
\end{document}

You will see something like this in the log:

> \box29=
\hbox(6.94444+1.94444)x29.72229
.\OT1/cmr/m/n/10 a
.\OT1/cmr/m/n/10 l
.\OT1/cmr/m/n/10 i
.\discretionary
..\OT1/cmr/m/n/10 -
.\OT1/cmr/m/n/10 q
.\OT1/cmr/m/n/10 u
.\OT1/cmr/m/n/10 e
.\OT1/cmr/m/n/10 t

With luatex you could analyse such a box to retrieve the text.
