=cut</pre><p>You can also use <code>NaturalDocs</code> or <code>Natural Docs</code> in place of <code>ND</code>. None of them are case sensitive. If for some reason you want to go back to POD documentation instead of using <code>=cut</code>, you can write <code>=end nd</code>.</p><p><b>Important:</b> The second form of just <code>=nd</code> is offered as a convenience but is not valid POD. Perl will skip over it and execute fine, but POD parsers will give errors and possibly include the unformatted text in the output. Use the longer, valid form unless you know for certain that no one will ever try to run POD on your code.</p></div><div class=Topic><a name=TextFiles></a><div class=TopicTitle>Text Files</div><p>Alternately, documentation can be included in text files. Any file with a .txt extension appearing in the source tree will be scanned for Natural Docs topics. It will be treated the same as a source file, meaning it will appear in the menu, its topics will be in the indexes, and its topics can be linked to from anywhere in the documentation. The only difference is you don’t need comment symbols.</p><p>Note that you still need to include topic headers, though. Anything before the first header will be ignored, and if the file doesn’t have any header lines at all, it will be ignored completely.</p><p>This method is convenient for documenting file formats, configuration settings, the general program architecture, or anything else that isn’t directly tied to a source file.</p></div><div class=Topic><a name=Topics></a><div class=TopicTitle>Keywords, Topics, and Scope</div><p>As you may have guessed, a topic in Natural Docs starts with a <code>“keyword: name”</code> line. You can have multiple topics per comment as long as you separate them with a blank line. The keywords aren’t case sensitive.</p><p>The list of keywords is pretty predictable: <code>Function</code>, <code>Class</code>, <code>Variable</code>, etc. Just use what they are. There are many synonyms as well, so you can use keywords like <code>Func</code>, <code>Procedure</code>, <code>Proc</code>, <code>Method</code> and <code>Constructor</code>. Look at the <a href="keywords.html">full list of keywords</a> to see everything that’s available.</p><p>The <a href="keywords.html">list of keywords</a> is separated into topic types. Each type gets its own index, and which specific keyword you use doesn’t matter. Some also have scoping rules or other behavior as noted.</p><div class=SubTopic>Scope</div><p>Like the code it’s documenting, Natural Docs topics have scope. This mostly has to do with <a href="#Linking">linking</a>: if you’re in a class you can link to its members by their name alone, but if you’re not, you have to use a notation like <code>class.member</code> or <code>class::member</code>.</p><p>If you have <a href="languages.html">full language support</a> and are documenting something that appears in the code, the scope will be handled automatically. If you’re using text files or only have basic language support, scoping follows these basic rules:</p><ul><li>Everything after a class topic (or <a href="keywords.html">anything that says “Starts Scope”</a>) is part of that class.</li><li>Everything after a section topic (or <a href="keywords.html">anything that says “Ends Scope”</a>) is global again.</li><li>File topics (or <a href="keywords.html">anything that says “Always Global”</a>) are global but do not change the scope for anything else.</li></ul><div class=SubTopic>List Topics</div><p>If you looked at the list, you saw that most of the keywords have plural forms. That’s for list topics, which let you document many small things without using the full syntax. Anything that appears in <a href="#DefinitionList">definition lists</a> within that topic will be treated as if it had its own topic. It will appear in the index

Of course, the alternative would be to automatically guess where links should be, but systems that do that typically pepper your sentences with unintentional links to functions called “is” or “on”. However, the Natural Docs syntax is still as minimal as possible. Simply surround any topic you want to link to with angle brackets. Natural Docs will keep track off all the topics and where they are defined, so you don’t need to use HTML-like syntax or remember what file anything is in. Also, if the link can’t be resolved to anything, Natural Docs leaves the angle brackets in the output so if something wasn’t intended to be a link (such as <code>#include <somefile.h></code>) it won’t be mangled.</p><pre class=Example>Let's link to function <Multiply>.</pre><div class=NDContent><p class=CParagraph>Let’s link to function <a href="#Example_Class.Multiply" class=LFunction id=link632 onMouseOver="ShowTip(event, 'tt3', 'link632')" onMouseOut="HideTip('tt3')">Multiply</a>.</p></div><p>Links and topic names are case sensitive, regardless of whether the language is or not.</p><p>When linking to functions, it doesn’t matter if you include empty parenthesis or not. Both <code><Function></code> and <code><Function()></code> will work. However, if you documented the function with parameters as part of the name, you will need to include those parameters whenever linking to it. It is recommended that you only include parameters in the topic name if you need to distinguish between two functions with the same name.</p><p>If the topic has a <a href="#Summaries">summary sentence</a>, hovering over the link will give it to you as a tooltip. If the topic has a prototype, that will be included as well. You can try it above.</p><div class=SubTopic>Scope</div><p>If a topic is <a href="#Topics">considered part of a class</a>, they are linked to using any of the three most common class/member notations: <code>class.member</code>, <code>class::member</code>, and <code>class->member</code>. Natural Docs will not be confused by <code><class->member></code>. Like in the language itself, if the topic you’re writing is in that class’ scope you can link to it simply as <code><member></code>.</p><p>If you have multi-level classes and packages, links can be relative as well. So if you’re in <code>Project::UI::Window::Base</code> and you want to link to <code>Project::UI::Button::Base</code>, just using <code><Button::Base></code> will work. Links will try to resolve to globals before relative because not everyone wants to use relative links, and this way they can ignore it without anything getting messed up.</p><div class=SubTopic>Plurals and Possessives</div><p>To make the documentation easier to write and easier to read in the source file, you can include plurals and possessives inside the angle brackets. In other words, you don’t have to use awkward syntax like <code><Object>s</code>, although that’s supported as well. You can simply write <code><Objects></code> and it will link to the symbol <code>Object</code> just fine. It can handle any plural and/or possessive form you can throw at it. I’m not kidding: <code>Foxes</code>, <code>Fox’s</code>, <code>Foxes’</code>, <code>Children</code>,

However, if you don’t like the page title Natural Docs has chosen for you, add a “<code>Title: [name]</code>” comment to the top of the file to override it. <code>Title</code> is a synonym of Section, so that will satisfy the second rule and make it the page title.</p></div><div class=Topic><div class=TopicTitle><a name=Summaries></a>Summaries</div><p>Summaries are automatically generated for every file, class, and section. You don’t have to do anything special to get them.</p><p>There are two things you may want to keep in mind when documenting your code so that the summaries are nicer. The first is that they use the first sentence in the topic as the description, so long as it’s plain text and not something like a bullet list. It will also appear in the tooltip whenever that topic is linked to.</p><p>The second is that you may want to manually add group topics to divide long lists and make the summaries easier to navigate. Natural Docs will automatically group them by type if you do not, but sometimes you want to be more specific. You don’t need to provide a description, just adding a “<code>Group: [name]</code>” comment is sufficient. Note that once you manually add a group automatic grouping is completely turned off for that class.</p><p>Here’s an example summary. Note that as before, when you hover over a link, you’ll get the prototype and summary line as a tooltip.</p><div class=NDSummary><div class=Summary><div class=STitle>Summary</div><div class=SBorder><table border=0 cellspacing=0 cellpadding=0 class=STable><tr><td class=SEntrySize><div class=SMain><div class=SEntry><a href="#Example_Class" >Example Class</a></div></div></td><td class=SDescriptionSize><div class=SMain><div class=SDescription>A example class that does arithmetic with functions for people scared of operators.</div></div></td></tr><tr><td><div class=SGroup><div class=SEntry><div class=SIndent1><a href="#Example_Class.Arithmetic_Functions" >Arithmetic Functions</a></div></div></div></td><td><div class=SGroup><div class=SDescription><div class=SIndent1></div></div></div></td></tr><tr class=SMarked><td><div class=SFunction><div class=SEntry><div class=SIndent2><a href="#Example_Class.Add" id=link1 onMouseOver="ShowTip(event, 'tt1', 'link1')" onMouseOut="HideTip('tt1')">Add</a></div></div></div></td><td><div class=SFunction><div class=SDescription><div class=SIndent2>Adds two integers.</div></div></div></td></tr><tr><td><div class=SFunction><div class=SEntry><div class=SIndent2><a href="#Example_Class.Subtract" id=link2 onMouseOver="ShowTip(event, 'tt2', 'link2')" onMouseOut="HideTip('tt2')">Subtract</a></div></div></div></td><td><div class=SFunction><div class=SDescription><div class=SIndent2>Subtracts two integers.</div></div></div></td></tr><tr class=SMarked><td><div class=SFunction><div class=SEntry><div class=SIndent2><a href="#Example_Class.Multiply" id=link3 onMouseOver="ShowTip(event, 'tt3', 'link3')" onMouseOut="HideTip('tt3')">Multiply</a></div></div></div></td><td><div class=SFunction><div class=SDescription><div class=SIndent2>Multiplies two integers.</div></div></div></td></tr><tr><td><div class=SFunction><div class=SEntry><div class=SIndent2><a href="#Example_Class.Divide" id=link4 onMouseOver="ShowTip(event, 'tt4', 'link4')" onMouseOut="HideTip('tt4')">Divide</a></div></div></div></td><td><div class=SFunction><div class=SDescription><div class=SIndent2>Divides two integers.</div></div></div></td></tr><tr><td><div class=SG
