bug in docbook-tools text backend using w3m

Christian Bünnig
Hey,

I've experienced a bug in the text backend of the docbook tools. The bug
is about converting from HTML to TEXT with w3m. The backend creates a
temporary HTML file to make a TEXT file from. However, the temporary
HTML has no '.html' suffix and in that case w3m does not convert it to
plain text - the resulting <FILE>.txt is still HTML.

Below is a workaround. I just appended '.html' to the variable HTML
(line 22). Now it works.

---------- snip -----------

# Backend to convert something into ASCII text
# Send any comments to Eric Bischoff <[hidden email]>
# This program is under GPL license. See LICENSE file for details.

if [ -x /usr/bin/lynx ]
then
  CONVERT=/usr/bin/lynx
  ARGS="-force_html -dump -nolist -width=72"
elif [ -x /usr/bin/links ]
then
  CONVERT=/usr/bin/links
  ARGS="-dump"
elif [ -x /usr/bin/w3m ]
then
  CONVERT=/usr/bin/w3m
  ARGS="-dump"
else
  echo >&2 "No way to convert HTML to text found."
  exit 1
fi

HTML=$(mktemp /tmp/html-XXXXXX).html || exit 1
trap 'rm -f "$HTML"; exit' 0 1 2 3 7 13 15

# Convert to HTML
$SGML_JADE -V nochunks -t sgml ${SGML_ARGUMENTS} >${HTML}
if [ $? -ne 0 ]
then exit 1
fi

# Convert from HTML to ASCII
${CONVERT} ${ARGS} ${HTML} > "${SGML_FILE_NAME}.txt"
if [ $? -ne 0 ]
then
  exit 2
fi

exit 0

---------- snip -----------

Here is some info about my configuration:

- DocBook-utils version 0.6.14 (jw version 1.1)
- w3m version 0.5.1+cvs-1.968
- Ubuntu 7.10

Btw .. the e-mail address <[hidden email]> seems to be not valid
anymore.

Regards,

Christian

Hi,
Actually I would prefer to modify ARGS of w3m as is suggested in
man pages and as is done in xmlto docbook txt formatter.
(done in attached patch - I'll commit that one to Fedora)

About Eric Bischoffs current address - after a bit of google
searching, it seems that now he is using [hidden email]
- but nothing guaranteed.

Greetings,
         Ondrej Vasik
