LaTeX2man -
A Documentation Tool

Dr. Jürgen Vollmer

2018/11/25

Version 1.29

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).

Table of Contents

Synopsis

latex2man [-ttransfile] [-cCSSfile] [-HMTL] [-h] [-V] [-Cname] [-achar] infile outfile

Description

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).

Options

-ttransfile
Translation for user defined LaTeX macros.
-cCSSfile
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:
-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.
-h
Show a help text.
-V
Show version information.

LaTeX commands

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.

Package Options

The latex2man package accepts the following options:

fancy
use the LaTeX package fancyheadings.
fancyhdr
use the LaTeX package fancyhdr.
nofancy
neither the LaTeX package fancyheadings nor fancyhdr are used.

The default option may be specified in the file latex2man.cfg.

Package Specific Environments

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.
a
|a \begin{description}
ab
|ab
abc
|abc
a
|a \begin{Description}
ab
|ab
abc
| abc
a
|a \begin{Description}[aa]
ab
|ab
abc
|abc

\today
25 November 2018 (see also the rcsinfo 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. 
     \textbf{\"a\"o\"u\"A\"O\"U\ss}
     \textbf{\"a}{\"o}{\"u}{\"A}{\"O}{\"U}{\ss}}
     \textbf{äöüÄÖÜß}

äöüÄÖÜß äöüÄÖÜß äöüÄÖÜß

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 &Auml; 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.

Conditional Text

latex2man preprocesses the LaTeX input to allow text to be used conditionally. A special sort of LaTeX comment is used for that purpose.

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
xyz OR !XYZ set

To check the conditional text feature, when latex2man is called with

-CHTML
the lines 1a, 2b, 3b, and 4b;
-CTEXI
the lines 1b, 2a, 3b, and 4b;
-CMAN
the lines 1b, 2b, 3a, and 4b;
-CLATEX
the lines 1b, 2b, 3b, and 4a;
calling LaTeX without preprocessing
all lines
should be shown:

1a. This text occurs only when viewing the HTML output.

2b. The TEXI conditional was not set.

3b. The MAN conditional was not set.

4b. The LATEX conditional was not set.

Translation of User Defined Macros

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:

Verbatim Environment

This
    {is}
        \texttt{a}
                  $test$
                         _of_
verbatim
<this is no HTML tag> and no @* TexInfo command

Subsection works

This is a \subsection.

Subsubsection works

This is a \subsubsection.

Subsubsection still works

This is another \subsubsection.

General Remarks

  1. Empty lines are typeset as paragraph separators.
  2. The arguments of the LaTeX commands must not be split over several lines.
  3. Do not nest calls to macros.
  4. 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.
  5. latex2man requires Perl version >= 5.0004_03.
  6. If you want to install the system with the distributed Makefile, you need GNU-make. If you don't have it, you should execute the steps shown in the Makefile manually.

tr rowstyle a row of a table specified as a Table environment
td cellstyle a cell of a table specified as a Table environment

Some Bug Fix Tests

Leading . and '
Now leading . and ' in generation troff output should work propperly, since a \& is added. Therfore the \Dot macro has been deleted.
Thanks to Frank.Schilder@Mathematik.Tu-Ilmenau.De.
Testcase 1:
'\n'
...
Testcase 2:
.foobar Testcase 3:
...

abc ...abc . efg ' 123

% in verbatim
A % in a \verb and verbatim-environment was not emitted correctly. Thanks to Aleksey Nogin nogin@cs.caltech.edu for the bug report and bug fix.

% abc
