Latex2man
is a tool to translate UNIX manual pages written with
LaTeXinto a format understood by the UNIX man(1)-command.
Alternatively HTML, TexInfo, or LaTeX code can be produced too.
Output of parts of the text may be suppressed using the conditional text
feature (for this, LaTeX generation may be used).
Latex2man
reads the file infile
and writes outfile.
The
input must be a LaTeX document using the latex2man
LaTeXpackage.
Latex2man
translates that document into the troff(1)
format using
the -man
macro package.
Using the -H
option, HTML code can be produced, instead of
troff(1).
With this option you can, optionally, specify a CSSfile
as an argument.
CSS (Cascading Style Sheets) allows you to control the appearance of the resulting HTML page.
See below for the names of CSS classes that are included in the HTML tags as attributes.
Using the -T
option, TexInfo code can be produced, instead of
troff(1).
Using the -M
option, troff(1)
input is produced.
Using the -L
option, LaTeX ouput can be produced, instead of
troff(1).
If you use the -H
you can also specify a file that contains CSS
style sheets. The link to the CSS file is inserted into the generatedHTML output using the
specified CSSfile
filename.
-M
Produce output suitable for the man(1)
command (default).
-H
Instead of producing output suitable for the man(1)
command, HTML code is produced (despite the name of the command).
-T
Instead of producing output suitable for the man(1)
command, TexInfo code is produced (despite the name of the command). The
generated .texi-file
may be processed with makeinfo(1)
(to produce an .info-file)
which in turn may be installed using
install-info(1).
The Info tags @dircategory and
@direntry are provided.
-L
The LaTeX source is written to the outfile.
This is
useful in conjunction with the -Cname
option.
-Cname
Output the conditional text for name.
If more
than one name should be given use quotes: -C'name1 name2 ...'
The following names are defined automatically:
-H defines HTML
-T defines TEXI
-M defines MAN
-L defines LATEX
-achar
Is used only in conjunction with -T.
Background:
TexInfo ignores all blanks before the first word on a new line. In order
to produce some additional space before that word (using \SP) some
character has to be printed before the additional space. By default this
is a . (dot). The char
specifies an alternative for that first
character. Giving a blank to
-a
supresses the indentation of a line.
Note: only for the first \SP of a series that char
is printed.
The LaTeX package latex2man
is used to write the Man-pages with
LaTeX.Since we translate into other text formats, not all LaTeX stuff can
be translated.
The following environments are provided by the package:
\begin{Name}{chapter}{name}{author}{info}{title}
The
Name
environment takes five arguments: 1. the Man-page chapter,
2. the name of the Man-page, 3. the author, 4. some short information
about the tool printed in the footline of the Man-page, and 5. a text
which is used as title, for HTML and LaTeX (it's ignored for output of
the Man-page or TeXinfo. The Name
environment must be the first
environment in the document. Processing starts with this environment. Any
text before this is ignored (exception: the setVersion and
setDate commands). (Note: all arguments of \begin{Name} must
be written on one line).
\begin{Table}[width]{columns}
The Table
environment takes two arguments: the first optional one specifies
a width of the last column, the second one gives the number of columns.
For example:
\begin{Table}[2cm]{3} Here & am & I \\\hline A 1 & A 2 & A 3 1 2 3 4 5 A 3 1 2 3 4 5 \\ B 1 & B 2 & B 3 \\ \end{Table}
will be typeset as:
Here
am
I
A 1
A 2
A 3 1 2 3 4 5 A 3 1 2 3 4 5
B 1
B 2
B 3
If no optional width
argument is given, all entries are
typeset left justified.
The width
is a length measured absolutly in cm.
Processing with LaTeX a p{width} column is typeset
as last column. The translation to troff(1)
commands
results in a lw(width)
column specification. Translating
to HTML and TexInfo ignores the width
parameter.
\hline may be used.
If the Man-page is formatted with troff(1)
and tables are used, the
tbl(1)
preprocessor should be called, usually by giving
a -t
to the call of troff(1).
When viewing the generated
manula page using man(1),
tbl(1)
is called automatically.
\begin{Description}
is the same as \begin{description}
\begin{Description}[label]
is similar to
\begin{description}, but the item labels have at minimum the size
of the (optional) word label.
The difference is visible only
in the DVI and PDF-output, not in the troff, TexInfo or HTML output.
The following standard LaTeX commands are accepted:
\section{..}
The section
macro takes one argument: the
name of the Man-page section. Each Man-page consists of several sections.
Usually there are the following sections in a Man-page: Name
(special handling as environment, c.f. above), Synopsis,
Description,
Options,
Files,
See Also,
Diagnostics,
Return Values,
Bugs,
Author,
version,
etc.
Synopsis
must be the first section after the Name
environment.
Note: Do not use LaTeX-macrosin section names.
\subsection{..}
works as well as
\subsubsection{..}
those.
\emph{..}
\emph{example} is typeset as example.
\textbf{..}
\textbf{example} is typeset as example.
\texttt{..}
\texttt{example} is typeset as example.
\underline{..}
\underline{example} is typeset as
example of underline.
\date{..}
uses .. as date.
\verb+..+
but only + is allowed as delimiter.
$<$
is typeset as <.
$>$
is typeset as >.
$<=$
is typeset as <=.
$>=$
is typeset as >=.
$=$
is typeset as =.
$<>$
is typeset as <>.
$\ge$
is typeset as $>$.
$\le$
is typeset as $<=$.
$\leftarrow$
is typeset as $<--$.
$\Leftarrow$
is typeset as $<==$.
$\rightarrow$
is typeset as $-->$.
$\Rightarrow$
is typeset as $==>$.
\{
is typeset as {.
\}
is typeset as }.
\$
is typeset as $.
\$
is typeset as $,should be used inside macro
arguments.
\_
is typeset as _.
\&
is typeset as &.
\#
is typeset as #.
\%
is typeset as %.
\,
is typeset as smaller blank - - (between the two -)
\-
is used to mark hyphenation in a word.
\\
is typeset as a linebreak or marks the end of a column in the
Table
environment.
\
(a \ followed by a blank) is typeset as a blank,
although it cannot be used at the beginning of a line to make indentation
(see the \SP
command).

LaTeXpackage).
\ss,\"a, ...
\ss = ß, \"a= ä, \"o= ö, \"u= ü,
\"A= Ä, \"O= Ö, \"U= Ü. It is allowed to surround these
macros in { and } in all places, even inside other macros, e.g.
If these letters are used in their LATIN-1 8-bit coding, they are
translated into the equivalent letter of the desired output format.
E.g. Ä
becomes Ä
in HTML and @"A
in texinfo.
\input{..}
Read and process the given filename.
Please note: the name of the LaTeX-macrosand its arguments must be contained in one line.
latex2man
preprocesses the LaTeX input to allow text to be used
conditionally. A special sort of LaTeX comment is used for that purpose.
%@% IF condition %@%
%@% ELSE %@%
%@% END-IF %@%
A line must contain only such a comment and nothing else. condition
is
a boolean expression containing ``names'' and operators. The names given with
the -Cname
option have the value ``true'', while all other names
occuring in the expression are assumed to be ``false''. If the evaluation of
the boolean expression results in the value ``true'', the text in the
``then''-part is used and the text in the optional ``else''-part is skipped
(and vice versa). The IF/ELSE/END-IF
may be nested. As boolean
operators the following are allowed:
||
boolean or
&&
boolean and
!
negation
( and ) for grouping are allowed.
For example:
%@% IF abc %@% abc set %@% IF xyz %@% xyz set %@% ELSE %@% xyz NOT set %@% END-IF %@%
%@% ELSE %@% abc NOT set %@% IF xyz || !XYZ %@% xyz OR !XYZ set %@% ELSE %@% xyz OR !XYZ NOT set %@% END-IF %@%
%@% END-IF %@%
Run this manual page through latex2man
with e.g.
-C'abc XYZ'
and have a look to the generated output.
(If simply running the LaTeX-document through LaTeX,all lines are shown in the
.dvi file).
abc NOT set

The user macro translation file (given by the [-ttransfile])
contains
Perl
commands specifying the translation of LaTeX macros defined by
the user. These macros may have none, one or two arguments. The following code
is expected:
Comments start with a # up to the end of the line.
For a macro \foo with no arguments, the following code must be
specified:
Translation to Man-Pages
$manMacro{'foo'} = '...';
Translation to HTML
$htmlMacro{'foo'} = '...';
Translation to TexInfo
$texiMacro{'foo'} = '...';
where ... is the translation.
For a macro \foo{..} with one argument, the following code must be
specified:
where ... is the translation. The 2a code is used before the
first argument, 2b between the two arguments and 2c is
typeset after the second argument is set.
The file latex2man.trans contains some example code.
The arguments of the LaTeX commands must not be split over several
lines.
Do not nest calls to macros.
Except the mentioned environment and macros, the usage of other LaTeX
environments or macros are not translated. Their usage will cause garbage
in the output.
latex2man requires Perl version >= 5.0004_03.
