NAME

htmldoc - convert html source files into html, postscript, or pdf.

SYNOPSIS

htmldoc [options] filename1.{html,md} [ ... filenameN.{html,md} ]

htmldoc [options] -

htmldoc [filename.book]

DESCRIPTION

Htmldoc(1) converts HTML and Markdown source files into indexed HTML,
PostScript, or Portable Document Format (PDF) files that can be
viewed online or printed. With no options a HTML document is
produced on stdout.

The second form of htmldoc reads HTML source from stdin, which allows
you to use htmldoc as a filter.

The third form of htmldoc launches a graphical interface that allows
you to change options and generate documents interactively.

COMMON MISTAKES

There are two types of HTML files - structured documents using
headings (H1, H2, etc.) which htmldoc calls "books", and unstructured
documents that do not use headings which htmldoc calls "web pages".

A very common mistake is to try converting a web page using:
htmldoc -f filename.pdf filename.html
which will likely produce a PDF file with no pages. To convert web
page files you must use the --webpage or --continuous options at the
command-line or choose Web Page or Continuous in the input tab of the
GUI.

The following command-line options are supported by htmldoc:

--batch filename.book
Generates the specified book file without opening the GUI.

ENVIRONMENT

HTMLDOC looks for several environment variables which can override
the default directories, display additional debugging information,
and disable CGI mode:

HTMLDOC_DATA
This environment variable specifies the location of htmldoc's
data and fonts directories, normally /usr/share/htmldoc or
C:/Program Files/HTMLDOC.

HTMLDOC_DEBUG
This environment variable enables debugging information that is
sent to stderr. The value is a list of any of the following
keywords separated by spaces: "all", "links", "memory",
"remotebytes", "table", "tempfiles", and/or "timing".

HTMLDOC_HELP
This environment variable specifies the location of htmldoc's
documentation directory, normally /usr/share/doc/htmldoc or
C:/Program Files/HTMLDOC/doc.

HTMLDOC_NOCGI
This environment variable, when set (the value doesn't matter),
disables CGI mode. It is most useful for using htmldoc on a web
server from a scripting language or invocation from a program.

EXAMPLES

Create a PDF file from a web site:
htmldoc --webpage -f example.pdf http://www.example.com/
Create a PostScript book from a directory of HTML files
htmldoc --book -f example.pdf *.html
