% ==== 1. ====
|
|
% Choose one of the following section headers and index entries;
|
|
% \section{} generates the section header,
|
|
% \bimodindex{} or \stmodindex{} generates an index entry for this
|
|
% module. Note that these should only be used for the defining entry
|
|
% for the module. Other references to the module should use
|
|
% \refbimodindex{} or \refstmodindex{}.
|
|
% The \label{module-spam} line is for the \seealso{} command.
|
|
|

\section{Built-in Module \sectcode{spam}} % If implemented in C

|
|
% ==== 2. ====
|
|
% Give a short overview of what the module does.
|
|
% If it is platform specific, mention this.
|
|
% Mention other important restrictions or general operating principles.
|
|
% For example:
|
|
|
|
The \code{spam} module defines operations for handling cans of Spam.
|
|
It knows the four generally available Spam varieties and understands
|
|
both can sizes.
|
|
|
|
Because spamification requires \UNIX{} process management, the module
|
|
is only available on genuine \UNIX{} systems.
|
|
|
|
|
|
% ==== 3. ====
|
|
% List the public functions defined by the module. Begin with a
|
|
% standard phrase. You may also list the exceptions and other data
|
|
% items defined in the module, insofar as they are important for the
|
|
% user.
|
|
|
|
The \code{spam} module defines the following functions:
|
|
|
|
% ---- 3.1. ----
|
|
% Redefine the ``indexsubitem'' macro to point to this module
|
|
% (alternatively, you can put this at the top of the file):
|
|
|
|
\renewcommand{\indexsubitem}{(in module spam)}
|
|
|
|
% ---- 3.2. ----
|
|
% For each function, use a ``funcdesc'' block. This has exactly two
|
|
% parameters (each parameters is contained in a set of curly braces):
|
|
% the first parameter is the function name (this automatically
|
|
% generates an index entry); the second parameter is the function's
|
|
% argument list. If there are no arguments, use an empty pair of
|
|
% curly braces. If there is more than one argument, separate the
|
|
% arguments with backslash-comma. Optional parts of the parameter
|
|
% list are contained in \optional{...} (this generates a set of square
|
|
% brackets around its parameter). Arguments are automatically set in
|
|
% italics in the parameter list. Each argument should be mentioned at
|
|
% least once in the description; each usage (even inside \code{...})
|
|
% should be enclosed in \var{...}.
|
|
|
|
\begin{funcdesc}{open}{filename\optional{\, mode\, buffersize}}
|
|
Open the file \var{filename} as a can of Spam. The optional
|
|
\var{mode} and \var{buffersize} arguments specify the read-write mode
|
|
(\code{'r'} (default) or \code{'w'}) and the buffer size (default:
|
|
system dependent).
|
|
\end{funcdesc}
|
|
|
|
% ---- 3.3. ----
|
|
% Data items are described using a ``datadesc'' block. This has only
|
|
% one parameter: the item's name.
|
|
|
|
\begin{datadesc}{cansize}
|
|
The default can size, in ounces. Legal values are 7 and 12. The
|
|
default varies per supermarket. This variable should not be changed
|
|
once the \code{open()} function has been called.
|
|
\end{datadesc}
|
|
|
|
% --- 3.4. ---
|
|
% Exceptions are described using a ``excdesc'' block. This has only
|
|
% one parameter: the exception name.
|
|
|
|
\begin{excdesc}{error}
|
|
Exception raised when an operation fails for a Spam specific reason.
|
|
The exception argument is a string describing the reason of the
|
|
failure.
|
|
\end{excdesc}
|
|
|
|
% ---- 3.5. ----
|
|
% There is no standard block type for classes. I generally use
|
|
% ``funcdesc'' blocks, since class instantiation looks very much like
|
|
% a function call.
|
|
|
|
|
|
% ==== 4. ====
|
|
% Now is probably a good time for a complete example. (Alternatively,
|
|
% an example giving the flavor of the module may be given before the
|
|
% detailed list of functions.)
|
|
|
|
Example:
|
|
|
|
\bcode\begin{verbatim}
|
|
>>> import spam
|
|
>>> can = spam.open('/etc/passwd')
|
|
>>> can.empty()
|
|
>>> can.close()
|
|
\end{verbatim}\ecode
|
|
%
|
|
% ==== 5. ====
|
|
% If your module defines new object types (for a built-in module) or
|
|
% classes (for a module written in Python), you should list the
|
|
% methods and instance variables (if any) of each type or class in a
|
|
% separate subsection. It is important to redefine ``indexsubitem''
|
|
% for each subsection.
|
|
|
|
\subsection{Spam Objects}
|
|
|
|
Spam objects (returned by \code{open()} above) have the following
|
|
methods.
|
|
|
|
\renewcommand{\indexsubitem}{(spam method)}
|
|
|
|
\begin{funcdesc}{empty}{}
|
|
Empty the can into the trash.
|
|
\end{funcdesc}
