SYNOPSIS

unroff [ -fhtml ] [ -me ] [ file | option... ]

OVERVIEW

When called with the -fhtml and -me options, the troff translator unroff loads the back-end for converting “me” documents to the Hypertext Markup Language (HTML) version 2.0.

Please read unroff(1) first for an overview of the Scheme-based, programmable troff translator and for a description of the generic options that exist in addition to -f and -m. The translation of basic troff requests, special characters, escape sequences, etc. as well as the HTML-specific options are described in unroff-html(1). For information about extending and programming unroff also refer to the Unroff Programmer’s Manual.

OPTIONS

The -me extension provides a number of keyword/value options in addition to those listed in unroff(1) and unroff-html(1):
signature (string)
  If non-empty, the value of this option together with a <hr> tag is appended to each HTML output file created. The substitute Scheme primitive (as described in the Programmer’s Manual) is applied to the value of the option, so that date, time, environment variables, etc. can be interpolated.
pp-indent (integer)
  The number of non-breakable spaces (as specified by the predefined Scheme variable nbsp) to generate for a paragraph created by the .pp macro. The default is 3. This option, as well as signature, is typically set in the user-preferences file ~/.unroff, or in a document-specific Scheme file or at the beginning of the document proper.

FILES

unroff reads and parses an ”me“ document composed of one or more input files. As usual, the special file name -’ can be used to interpolate standard input. If no file name is given in the command line, unroff reads from standard input.

The resulting HTML document is sent to standard output, unless a file name prefix is assigned to the document option.

EXAMPLE

To translate an “me” document composed of several input files, unroff could be invoked like this:







intro.me 1.me 2.me 3.me app.me

The output file will have the name “thesis.html”.

DESCRIPTION

The following -me macros are translated (in addition to any user-defined macros):



        .(b     .)b     .(c     .)c     .(d     .)d     .(f
        .)f     .(l     .)l     .(q     .)q     .(x     .)x
        .(z     .)z     .b      .bi     .bx     .hl     .i
        .ip     .np     .pd     .q      .r      .rb     .sz
        .sh     .u      .uh     .xp     .++     .+c

These predefined strings and number registers are recognized:

        \*(lq   \*(rq   \*-     \*(mo   \*(dw   \*(dy   \*(td
        \n($c   \n($d   \n($f   \n($m   \n($n   \**     \*#

In addition, a number of macros are either silently ignored or cause a warning to be printed, because their function either cannot be mapped to HTML 2.0 elements or assumes a page structure:

        .$H     .$f     .$h     .1c     .2c     .ac     .ar
        .bc     .ef     .eh     .fo     .he     .hx     .lh
        .ll     .m1     .m2     .m3     .m4     .of     .oh
        .pa     .ro     .sk     .th     .xl

Finally, these macros are not implemented, but could be in a future version:

        .sx

The font switching macros are based on changes to the fonts ‘R’, ‘I’, and ‘B’, as explained under FONTS in unroff-html(1). Of course, this fails if the fonts (which are mounted on startup) are unmounted by explicit .fp requests.

The special characters

        \(!< and \(!>

respectively generate < and > in the resulting html. These permit html elements to be put directly into the document text, as in e.g.

.Hr -symbolic next "\(!<img src=""next.gif"" alt=""next""\(!>"

to generate a reference to some other part of the document via a selectable image.

BUGS

The macro .ul is currently mapped to a call to .i, as underlining is not supported by the HTML back-end of unroff 1.0.

The section setting options of the .sh macro are not implemented.
