vilistextum

VILISTEXTUM(1)						      General Commands Manual						    VILISTEXTUM(1)

NAME

       vilistextum - html to ascii converter

SYNOPSIS

       vilistextum [OPTIONS] [inputfile |-] [outputfile | -]

DESCRIPTION

       vilistextum is a html to ascii converter specifically programmed to get the best out of incorrect html.

OPTIONS

       inputfile,- resp. outputfile,-
	      replace inputfile with '-' for reading from standard input, likewise outputfile with '-' for writing to standard output.

       -a, --no-alt
	      don't output anything for IMG tags even if they have an ALT attribute. Implies --no-image.

       -c, --convert-tags
	      some tags will be converted to special characters.

       -e, --errorlevel NUMBER
	      increase level of verbosity for error messages (0: No error messages).

       -i, --defimage STRING
	      IMG tags without alt attribute are output as [STRING].

       -l, --links
	      numbers the links in the document and creates footnotes of each link at the end of the file.

       -k, --links-inline
	      print the links directly after the html tag.

       -m, --dont-convert-characters
	      don't convert the entities from windows1252 (&#128;-&#159; and their proper entity names)

       -n, --no-image
	      don't output [Image] for IMG tags that have no ALT attribute.

       -p, --palm
	      output text more suitable for reading on a PDA.

       -r, --remove-empty-alt
	      if there is an empty ALT attribute in a IMG tag (eg <IMG href="..." alt="">), don't output '[]'.

       -s, --shrink-lines [NUMBER]
	      if there are more than NUMBER empty lines, output only NUMBER. Default: 1.

       -t, --no-title
	      don't output title.

       -w, --width NUMBER
	      maximum line width.

       -h, --help
	      display this help and exit

       -v, --version
	      output version information and exit

MULTIBYTE OPTIONS (Only available if compiled with multibyte support)
       -u, --output-utf-8
	      instead of the character set of the html document, everything will be output as utf-8.

       -x, --translit
	      use the //TRANSLIT feature of libiconv. Consult the iconv manual for details.

       -y, --charset CHARSET
	      if the HTML document doesn't provide a character set in the meta tags, use CHARSET.

LIMITATIONS

       The rendering of tables is not very good.

       The handling of OL is incomplete. The program treats it as UL and more than 10 nested lists confuse it.

       Text is never justified.
