<P>
|
|
It has been mentioned a few times already the importance of clearly
|
|
documenting your files and library files. For the most part, you can
|
|
use comments in your files; but in library files you use the
|
|
D<SMALL>OC</SMALL> directive.
|
|
|
|
<P>
|
|
In addition to the commands listed in this chapter, you should also
|
|
note <A HREF="node6.html#sec-grooves">D<SMALL>EF</SMALL>G<SMALL>ROOVES</SMALL></A>).
|
|
|
|
<P>
|
|
For some real-life examples of how to document your library files,
|
|
look at any of the library files supplied with this distribution.
|
|
|
|

|
|
|
|
<P>
|
|
A D<SMALL>OC</SMALL> command is pretty simple:
|
|
|
|
<P>
|
|
|
|
<TABLE ALIGN="CENTER" CELLSPACING=0 CELLPADDING=5 BGCOLOR="OldLace" BORDER=3>
|
|
<TR> <TD>
|
|
|
|
<BLOCKQUOTE><B>Doc This is a documentation string! </B></BLOCKQUOTE>
|
|
|
|
</TD></TR></TABLE>
|
|
|
|
<P>
|
|
In most cases, D<SMALL>OC</SMALL>s are treated as C<SMALL>OMMENT</SMALL>s. However,
|
|
if the <I>-Dx</I><A NAME="tex2html68"
|
|
HREF="#foot11348"><SUP>22.1</SUP></A> option is given
|
|
on the command line, D<SMALL>OC</SMALL>s are processed and printed to standard
|
|
output.
|
|
|
|
<P>
|
|
For producing the <I>
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> Standard Library Reference</I> a trivial
|
|
Python program is used to collate the output generated with a command
|
|
like:
|
|
|
|
<P>
|
|
|
|
<TABLE ALIGN="CENTER" CELLSPACING=0 CELLPADDING=5 BGCOLOR="OldLace" BORDER=3>
|
|
<TR> <TD>
|
|
|
|
<BLOCKQUOTE><B>$ mma -Dx -w /usr/local/lib/mma/swing </B></BLOCKQUOTE>
|
|
|
|
</TD></TR></TABLE>
|
|
|
|
<P>
|
|
Note, the '-w' option has been used to suppress the printing of warning
|
|
messages.

|

|
|
As part of the documentation package, there is a A<SMALL>UTHOR</SMALL>
|
|
command:
|
|
|
|
<P>
|
|
|
|
<TABLE ALIGN="CENTER" CELLSPACING=0 CELLPADDING=5 BGCOLOR="OldLace" BORDER=3>

|
<TR> <TD>
|

<BLOCKQUOTE><B>Author Bob van der Poel </B></BLOCKQUOTE>
|
|
|
|
</TD></TR></TABLE>
|
|
|
|
<P>
|
|
Currently A<SMALL>UTHOR</SMALL> lines are processed and the data is saved, but
|
|
never used. It may be used in a future library documentation
|
|
procedures, so you should use it in any library files you write.
