  32. <P ALIGN="left"> Connection Muse is free open-source software that you may
  33. use without charge and freely distribute to other users in accordance with
  34. the
  35. <a href="license.htm" target="_blank">GNU General Public License</a>. If you
  36. use the system in a published hypertext, we ask that you include a
  37. credit
  38. on the title page or credits page. For example:</P>

  42. Web site at http://www.wordcircuits.com/connect.</P>
  43. <P ALIGN="left">&nbsp;</P>
  44. <H3 ALIGN="left"><A NAME="HowItWorks"></A>How the System Works</H3>
  45. <P ALIGN="left"> Connection Muse consists of two components: the Connection
  46. Library and the Connection Toolkit. The Library is a collection of JavaScript
  47. functions contained in a file called <I>connect.js.</I>
  48. This is the code that makes the system work and it must be loaded by any HTML
  49. document in which you wish to use Connection features. The Toolkit aids you in
  50. adding Connection elements to your hypertexts.</P>
  51. <P ALIGN="left">Connection elements (such as Conditional Links or randomly generated
  52. text) are created by inserting JavaScript functions into your text at appropriate
  53. places. When the document is viewed in a browser, the JavaScript functions you
  54. have added call the main library to perform their tasks. You can add Connection
  55. functions to your work in two ways. You can type in the JavaScript functions
  56. manually or you can use one of the Connection Tools to automatically generate
  57. the function code you need.</P>
  58. <P ALIGN="left">Many of Connection Muse's features rely upon a reading history
  59. that is created while your hypertext is read. The history is a list of all the
  60. nodes (that is, HTML pages) that have been visited during a reading and it is
  61. updated every time a new node is viewed by the browser. The history is stored
  62. in a cookie, which is a collection of data that a browser can save on the hard
  63. disk after visiting a Web site. Your readers must therefore have cookies enabled
  64. on their browsers for Connection Muse to work properly. They must also
  65. have JavaScript enabled.</P>
  66. <P ALIGN="left">&nbsp;</P>
  67. <h3 ALIGN="left"><a name="Demos" id="Demos"></a>Demos</h3>
  68. <P ALIGN="left">To see Connection Muse in action, you can run the Connection
  69. Muse Demos:</P>
  70. <P ALIGN="left">The <a href="demos/simple/index.html" target="_blank">Simple

  72. <P ALIGN="left">The <a href="demos/components/start.htm" target="_blank">Component
  73. Demo</a> presents some more sophisticated approaches. There are two windows
  74. in this demo, and you can read the story either by clicking on links in
  75. the main window or clicking on the squares in the Story Component
  76. window
  77. that appears at the left of the screen. <a href="#Component_Demo">More about this demo</a>.</P>

  79. <h3 ALIGN="left"> <a name="Limitations"></a>System Limitations</h3>
  80. <P ALIGN="left">Currently a history record can safely contain a maximum of about
  81. 1,400 nodes. This limit is the result of restrictions imposed on cookie length
  82. by Microsoft Internet Explorer. To achieve this maximum history capacity, the
  83. author must create a list of node names that the system will use to generate
  84. short IDs for nodes. If the list of node names is not created, the history record
  85. will be limited to approximately 400-1,000 nodes with Microsoft Internet Explorer
  86. and about 8,000-16,000 nodes with Netscape Navigator. The exact number of nodes
  87. that can be accommodated depends upon the length of HTML filenames that are
  88. used in the hypertext. (Netscape Navigator will support a history record up
  89. to 80,000 characters long, while Microsoft Internet Explorer limits the history
  90. to 4,000 characters.) Without the list of node names, performance may also be
  91. slow with very large hypertexts.</P>

  93. <h2 ALIGN="center"><A NAME="Preparing"></A>Preparing Your Hypertext to Use the
  94. System</h2>
  95. <p ALIGN="center">&nbsp;</p>
  96. <h3><a name="Basic_Procedures"></a>Basic Procedures</h3>
  97. <P>1. <B>Copying the System Files</B>
  98. <P>The Connection Muse system files are contained in the compressed file <i><a href="http://www.wordcircuits.com/connect/MuseDoc&Files1.zip">MuseDoc&amp;Files1.zip</a></i> in
  99. a folder called <i>system</i>.
  100. <P>It is easiest to use the system if all the HTML files that constitute your
  101. hypertext are in one directory, though the system does support multiple directories.
  102. Copy the system files <I>connect.js</I> and <I>config.js</I> into the directory
  103. where your hypertext is located (or the root directory of your hypertext if
  104. it uses multiple directories).
  105. <P><B>2. Editing the Configuration File</B>
  106. <P>Open <I>config.js</I> in an ASCII text editor (such as Notepad in Windows or
  107. SimpleText on the Mac). This file contains the configuration information for
  108. your hypertext. Find the following line:
  109. <P><CODE>histCookieName = &quot;HypertextName&quot;</CODE>
  110. <P>Change <CODE>HypertextName</CODE> to a name that represents your hypertext.
  111. The name cannot include spaces, commas, or semicolons. Be sure to leave the
  112. quotation marks intact.
  113. <P>You will
  114. also see a line that reads as follows:
  115. <P><CODE>totalNodes = 0</CODE>
  116. <P>This tells the system how many nodes your hypertext contains. Providing this
  117. information is only necessary if you wish to use functions that determine how
  118. much of the total work has been read. If you wish to use these features, change
  119. the &quot;0&quot; to the total number of nodes. (Do not put quotation marks
  120. around the number.) If the number of nodes changes, you will have to manually
  121. change this number, so it is best to wait until the work is finished before
  122. you set this variable.
  123. <P><B>3. Adding the Library-Loading Code</B></P>
  124. <P>Any HTML page that makes use of Connection System features must contain in
  125. its header the JavaScript code that loads the two system files (<i>connect.js</i>
  126. and <i>config.js</i>). Any node you want recorded in the history must also load
  127. these files. Each time <i>connect.js</i> is loaded, the node that loads it is
  128. added to the history. If you are working with a very large hypertext and want
  129. to use the features designed to accommodate large works, skip the rest of this
  130. section and follow the instructions in the next section, <a href="#Large_Hypertexts">Working
  131. with Very Large Hypertexts</a>. If your hypertext contains multiple directories,
  132. see <a href="#Multiple_Directories">Working with Multiple Directories</a>.</P>
  133. <P><B>If you are beginning a new hypertext. </B>Use the file <I>template.htm</I>
  134. as a template for creating any new page that should load the system files. This
  135. is a blank HTML page that contains the code for loading the files.</P>
  136. <P><B>If you are adding Connection System features to an existing hypertext.</B>
  137. You must add the appropriate code to each page that should load the system files.
  138. To add this code, view your document in ASCII or HTML editing mode and insert
  139. the following text between the <CODE>&lt;HEAD&gt;</CODE> and <CODE>&lt;/HEAD&gt;</CODE>
  140. tags:</P>
  141. <P><CODE>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;config.js&quot;&gt;&lt;/SCRIPT><BR>
  142. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;connect.js&quot;&gt;&lt;/SCRIPT></CODE>
  143. <P>The
  144. easiest way to do this is to use a text editor or HTML editor to perform a
  145. global search and replace on all the HTML files in your hypertext. Replace this
  146. text:<P> <CODE>&lt;/HEAD&gt;</CODE>
  147. <P>with this text:
  148. <P><CODE>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;config.js&quot;&gt;&lt;/SCRIPT><BR>
  149. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;connect.js&quot;&gt;&lt;/SCRIPT><BR>
  150. &lt;/HEAD&gt;</CODE>
  151. <P>
  152. <h3 ALIGN="LEFT"><b><a name="Large_Hypertexts"></a></b>Working with Very Large
  153. Hypertexts </h3>
  154. <P ALIGN="LEFT">Connection Muse provides special features for accommodating
  155. very large hypertexts containing more than 100 nodes or so. These features improve
  156. performance and allow history records of up to about 1400 nodes. (See <a href="#Limitations">System
  157. Limitations</a> for more about history length limits.)
  158. <P ALIGN="LEFT"><b>Short IDs</b>
  159. <P ALIGN="LEFT">To allow more history information to be stored in the history
  160. record, the system can substitute 1-3 character IDs for full filenames. To use
  161. this feature, you must create an array (or list) containing the filename of
  162. every node in your hypertext. To do this, you must add a line to the end of
  163. your config.js file using the following syntax:
  164. <P ALIGN="LEFT"><code>var nodesList = [<i>filename1, filename2,...filenameN</i>]</code>
  165. <P ALIGN="LEFT">Replace <code><i>filename1, filename2,</i></code> and so on, with
  166. the names of the files in your piece. If the nodes in your piece were called
  167. &quot;node1.htm,&quot; &quot;node2.htm,&quot; &quot;node3.htm,&quot; &quot;node4.htm,&quot;
  168. and &quot;node5.htm,&quot; the added line would look like this:
  169. <P ALIGN="LEFT"><code>var nodesList = [&quot;node1.htm&quot;, &quot;node2.htm&quot;,
  170. &quot;node3.htm&quot;, &quot;node4.htm&quot;, &quot;node5.htm&quot;]</code>
  171. <P ALIGN="LEFT">If you accidentally omit a few filenames from the list, this will
  172. not cause any errors in program execution but will reduce the amount of space
  173. available in the history record.
  174. <P ALIGN="LEFT">It's recommended that you store the short IDs in a Persistent
  175. System Frame, as described in the next section. This will guarantee the fastest
  176. performance.
  177. <P ALIGN="LEFT">If you choose not to use a Persistent System Frame, you must follow
  178. these steps: Copy the file <i>ids.js</i> from the <i>frame</i> folder (which
  179. is located inside the <i>system</i> folder) into the directory where your hypertext
  180. is located (or the root directory of your hypertext if it uses multiple directories).
  181. Then add the appropriate code to your hypertext so that each page loads <i>ids.js</i>.
  182. Open each page in ASCII or HTML editing mode and insert the following text between
  183. the <code>&lt;HEAD&gt;</code> and <code>&lt;/HEAD&gt;</code> tags:
  184. <p><code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;ids.js&quot;&gt;&lt;/SCRIPT></code>
  185. <p>Alternatively you can do a global search and replace to make these changes.
  186. <P ALIGN="LEFT"><b>Persistent System Frames</b>
  187. <P ALIGN="LEFT">To improve performance and simplify working with Short IDs or
  188. multiple directories, you can create a frame in your hypertext that is used
  189. solely to store system information so that this information won't have to be
  190. reloaded every time a new page is displayed.
  191. <P ALIGN="LEFT">If you are not using short IDs, copy all the files from the <i>frame</i>
  192. folder (which is located inside the <i>system</i> folder) into the directory
  193. where your hypertext is located (or the root directory of your hypertext if
  194. it uses multiple directories). If you are using short IDs, copy all the files
  195. from the <i>frame_ids</i> folder (which is also located inside the <i>system</i>
  196. folder) into the directory where your hypertext is located.
  197. <P ALIGN="LEFT">The file <i>frameset.htm</i> (or <i>frameset_ids.htm</i> if you
  198. are using short IDs) contains a frameset containing a Persistent System Frame.
  199. You can use this frameset as the starting file for the hypertext. (You can rename
  200. this file to anything you want.)
  201. <P ALIGN="LEFT">If you want to add a Persistent System Frame to an existing frameset
  202. rather than using <i>frameset.htm</i> or <i>frameset_ids.htm</i>, you must name
  203. the new frame &quot;systemFrame.&quot; Since this frame will be used only to
  204. store variable values, you should locate it in an unobtrusive place, such as
  205. at the bottom of the window, and set its size to &quot;1&quot; (which is the
  206. smallest size value the browser will accept). This new frame must then load
  207. the file <i>system.htm</i> (or <i>system_ids.htm</i> if you are using short
  208. IDs).
  209. <P ALIGN="LEFT"><i>start.htm</i> will be the first node in your hypertext, so
  210. you can modify this file as appropriate. (If you rename this file, you will
  211. also have to revise the frame definition in <i>frameset.htm</i> or <i>frameset_ids.htm</i>
  212. accordingly.) Each new node in your hypertext should be created from a copy
  213. of <i>frame_template.htm</i>. Both <i>start.htm</i> and <i>frame_template.htm</i>
  214. are blank pages containing JavaScript in their headers.
  215. <P ALIGN="LEFT"> If you are adding the Persistent System Frame to an existing
  216. hypertext, you must update all the pages in the hypertext so that each file
  217. contains the following lines of code in its header (between the <code>&lt;HEAD&gt;</code>
  218. and <code>&lt;/HEAD&gt;</code> tags):
  219. <P ALIGN="LEFT"><code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;config.js&quot;&gt;&lt;/SCRIPT><br>
  220. &lt;SCRIPT LANGUAGE=&quot;javascript&quot;&gt;var connectWin=parent.systemFrame&lt;/SCRIPT><br>
  221. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;connect-f.js&quot;&gt;&lt;/SCRIPT></code>
  222. <p>The easiest way to do this is to use a text editor or HTML editor to perform
  223. a global search and replace on all the HTML files in your hypertext. Replace
  224. this text:
  225. <p> <code>&lt;/HEAD&gt;</code>
  226. <p>with this text:
  227. <p><code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;config.js&quot;&gt;&lt;/SCRIPT><br>
  228. &lt;SCRIPT LANGUAGE=&quot;javascript&quot;&gt;var connectWin=parent.systemFrame&lt;/SCRIPT><br>
  229. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;connect-f.js&quot;&gt;&lt;/SCRIPT><br>
  230. &lt;/HEAD&gt;</code>
  231. <p>Note that if your files already contain this line:
  232. <p><code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;connect.js&quot;&gt;&lt;/SCRIPT></code>
  233. <p>you should delete it. This line should only appear in <i>system.htm</i>.
  234. <p>
  235. <h3 ALIGN="LEFT"><a name="Multiple_Directories"></a>Working with Multiple Directories</h3>
  236. <P ALIGN="LEFT">If your hypertext files are contained within more than one directory,
  237. put Connection Muse files in the root directory. Then follow the appropriate
  238. instructions below, depending upon whether or not you are using a Persistent
  239. System Frame.
  240. <P ALIGN="LEFT"><b>When Using a Persistent System Frame</b>
  241. <P ALIGN="LEFT">Any new pages added to subdirectories under the root directory
  242. must be created from copies of the file <i>subdir_frame_template.htm</i> (which
  243. is located inside the <i>system/subdir</i> folder). For example, if the root
  244. directory is <code>/hypertext</code> and you create new pages in a directory
  245. called <code>/hypertext/chapter1</code>, these pages must be based upon <i>subdir_frame_template.htm.</i>
  246. <P ALIGN="LEFT">Any pages not based upon the template must have the following
  247. lines of code added to their headers:
  248. <p align="LEFT"> <code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../config.js&quot;&gt;&lt;/SCRIPT><br>
  249. &lt;SCRIPT LANGUAGE=&quot;javascript&quot;&gt;var connectWin=parent.systemFrame&lt;/SCRIPT></code><code><br>
  250. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../connect-f.js&quot;&gt;&lt;/SCRIPT></code>
  251. <P ALIGN="LEFT"><b>When Not Using a Persistent System Frame</b>
  252. <P ALIGN="LEFT">Any new pages added to subdirectories under the root directory
  253. must be created from copies of the file <i>subdir_template.htm</i> (which is
  254. located inside the <i>system/subdir</i> folder).
  255. <P ALIGN="LEFT">Any pages not based upon the template must have the following
  256. lines of code added to their headers:
  257. <P ALIGN="LEFT"><code>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../config.js&quot;&gt;&lt;/SCRIPT><br>
  258. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../connect.js&quot;&gt;&lt;/SCRIPT></code>
  259. <P ALIGN="LEFT">The following line must be added to <i>config.js</i>:
  260. <P ALIGN="LEFT"><code>var baseDirectory=&quot;<i>directoryName</i>&quot;</code>
  261. <P ALIGN="LEFT"> <code><i>directoryName</i></code> should be the name of the root
  262. directory. For example, if the root directory is <code>/hypertext</code>, the
  263. line should read:
  264. <P ALIGN="LEFT"><code>var baseDirectory=&quot;hypertext&quot;</code>
  265. <P ALIGN="LEFT"><b>When Using More Than One Level of Subdirectory</b>
  266. <P ALIGN="LEFT">Any pages located in a subdirectory within a subdirectory (for
  267. example, in <CODE>/hypertext/chapter1/part1</CODE>) must use <code>../../</code>
  268. instead of <code>../</code> in their header code, as in the following example:
  269. <P ALIGN="LEFT"><CODE>&lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../../config.js&quot;&gt;&lt;/SCRIPT><BR>
  270. &lt;SCRIPT LANGUAGE=&quot;javascript&quot; SRC=&quot;../../connect.js&quot;&gt;&lt;/SCRIPT></CODE>
  271. <P ALIGN="LEFT"><b>Node Names</b>
  272. <P ALIGN="LEFT">Whenever a node name is used in an array or as a parameter to
  273. a function, it should be preceded by a forward slash (/) and include the directory
  274. name if the node is not located in the root directory. For example, if <i>node1.htm</i>
  275. is located in <code>/hypertext</code> and <code>/hypertext</code> is the root
  276. directory, the correct name for it would be &quot;/node1.htm&quot; in a function
  277. such as this:
  278. <P ALIGN="LEFT"><code>link(&quot;/node1.htm&quot;, &quot;click here&quot;)</code>
  279. <P ALIGN="LEFT">If <i>node1.htm</i> is located in <code>/hypertext/chapter1</code>,
  280. the correct name for it would be &quot;/chapter1/node1.htm&quot;:
  281. <P ALIGN="LEFT"><code>link(&quot;/chapter1/node1.htm&quot;, &quot;click here&quot;)</code>
  282. <P ALIGN="LEFT">
  283. <h3 ALIGN="LEFT"><a name="Entry_Page"></a>Preparing an Entry Page</h3>
  284. <P ALIGN="LEFT">When a reader returns to your hypertext after having read part
  285. of it, you may want the opening page to give that reader the options of continuing
  286. the reading where it was left off or starting a new reading from the beginning.
  287. You can do this by creating an Entry Page. If the reader has not read any of
  288. the hypertext, when the Entry Page is loaded it displays a link labeled &quot;Come
  289. In,&quot; which leads to the first node of the hypertext. If the reader is returning
  290. to the hypertext, the following message and options will be presented when the
  291. Entry Page is loaded:</P>
  292. <TABLE WIDTH="85%" BORDER="1">
  293. <TR>
  294. <TD> <BR>
  295. You have returned to a reading in progress. Choose an option:
  296. <UL>
  297. <LI>Resume the reading where you left off.</LI>
  298. <LI>Start over and delete the current history.</LI>
  299. </UL>
  300. </TD>
  301. </TR>
  302. </TABLE>
  303. <P ALIGN="LEFT">Clicking on the first option takes the reader to the last node
  304. read during the previous reading session. Clicking on the second option deletes
  305. the history record and takes the reader to the first node of the hypertext.
  306. <P ALIGN="LEFT">The Entry Page will also present the reader with a list of filenames
  307. of all the nodes that have been read. If you create a <a href="#Title_Array">Title
  308. Array</a>, the titles of nodes will be included in the list as well.
  309. <P ALIGN="LEFT">Letting the reader delete the history record when starting a new
  310. reading ensures that all the functions will perform accurately and keeps the
  311. record from becoming longer than necessary and slowing down performance. It
  312. also will prevent the reader from filling up the history record when rereading
  313. a very long hypertext.
  314. <P ALIGN="LEFT">Follow these steps to create an Entry Page:
  315. <OL>
  316. <LI> Copy <i>entry.htm</i> (located in the <i>system</i> folder) into the directory

  318. copy the file <i>entry-f.htm</i> (located in the <i>frame</i> folder within
  319. the <i>system</i> folder) instead, if it has not already been copied into

  701. <p><code>annotatedTextPrefixDefault</code> specifies text or HTML code to be placed
  702. immediately before every piece of annotated text and <code>annotatedTextSuffixDefault</code>
  703. specifies text or HTML code to be placed immediately after every piece of annotated
  704. text. This can be used to mark all the annotated text in a hypertext. The default
  705. value is no prefixes or suffixes.</p>
  706. <p> For example, the following line puts an asterisk after all the text created
  707. with the display() function:</p>
  708. <p><code>annotatedTextSuffixDefault = &quot;*&quot;</code></p>
  709. <p>&nbsp;</p>

  719. titleStatus = true | false</CODE></P>
  720. <P>These attributes control annotations for links or annotated text that appear
  721. as pop-up text messages or status bar messages. <CODE>popupTextDefault</CODE>
  722. specifies a default text string that will be displayed in a pop-up box whenever
  723. the mouse pointer is moved over a link created with link() or text created with
  724. display(). The default is &quot;null&quot; for no pop-up display.</P>
  725. <P><code>popupTextColorDefault</code> specifies the color of pop-up text. This
  726. may be either the name of a color enclosed in quotation marks (&quot;red&quot;,
  727. &quot;green&quot;, etc.) or a hexadecimal color value. The default value is
  728. <code>null</code>, which causes the text color of the document to be used. <code>popupBgColorDefault</code>
  729. determines the background color of the pop-up text. The default setting is <code>&quot;#FFFFCC&quot;,</code>
  730. which sets the background color to pale yellow.</P>
  731. <P><code>popupAttDefault</code> specifies attributes that determine the appearance
  732. of the pop-up text. This text is formatted by means of an HTML table, so <code>popupAtt</code>
  733. will accept any string of attributes allowed by the HTML &lt;TABLE&gt; tag.
  734. The attributes are entered in the following format:</P>
  735. <p> <code>popupAttDefault = '<i>attribute1</i>=&quot;<i>value1</i>&quot; [<i>attribute2</i>=&quot;<i>value2</i>&quot;]'</code></p>
  736. <p>This example sets a specific width for the pop-up box:</p>
  737. <p><code>popupAttDefault = 'width=&quot;100&quot;'</code> </p>
  738. <P>The pop-up text feature relies on DHTML and therefore will only work in version
  739. 4 or later browsers. <FONT COLOR="#FF0000">[Note: A bug in the current version
  740. prevents pop-up text from working properly in Netscape Navigator if the relevant
  741. link appears in text that is centered or in a table.]</FONT></P>
  742. <P><CODE>statusTextDefault</CODE> functions the same way as <CODE>popupTextDefault</CODE>,
  743. except the specified annotation appears in the browser's status bar. The default
  744. is &quot;null&quot; for no status bar message.</P>
  745. <P>Both <CODE>popupTextDefault</CODE> and <CODE>statusTextDefault</CODE> can be
  746. overridden by specifications made in individual coals to either link() or display().</P>
  747. <P>If <CODE>deadLinkPopup</CODE> or <CODE>deadLinkStatus </CODE>is set to &quot;true,&quot;
  748. the specified pop-up or status bar annotation will be displayed by dead links.
  749. (See Link Appearance for discussion of dead links.) The default for both these
  750. attributes is &quot;false.&quot;</P>
  751. <P>If <CODE>titlePopup</CODE> or <CODE>titleStatus </CODE>is set to &quot;true,&quot;
  752. node titles specified in a Title Array will be used as pop-up or status bar
  753. annotations for links to the corresponding nodes. The default for both these
  754. attributes is &quot;false.&quot;</P>
  755. <P>For example, the following lines specify default text to appear in the status
  756. bar and specify that node titles be displayed as pop-up annotations for live

  775. <h3><a name="Item_Arrays"></a>5. Item Arrays</h3>
  776. <P> Many of the Connection functions support multiple items as parameters, allowing
  777. you to perform such operations as randomly selecting one of several node filenames
  778.  
  779. (see <a href="reference.htm" target="_top">Function Reference</a>). If you
  780. wish to use the same set of items repeatedly in different functions, you can
  781. define
  782. the set as an item array in <i>config.js</i>. You can then use the array name
  783. as a function parameter instead of entering each individual item name as a
  784. separate
  785. parameter. You can use the <a href="#Item_Array_Tool">Item Array Tool</a> to
  786. create item arrays.</P>
  787. <P>Item arrays take the following form:</P>
  788. <P><i><code>arrayName</code></i><code> = [<i>item1</i>, <i>item2</i>, <i>item3,
  789. ...</i>]</code></P>
  790. <P>For example, this line added to <i>config.js</i> defines an array of four node
  791. filenames:</P>
  792. <P><code>someNodes = ["1.htm", "2.htm", "3.htm", "4.htm"]</code></P>
  793. <P>The array name <code>someNodes</code> can then be used in functions instead
  794. of the names of the four nodes. For example, this code would create a link to
  795. one of the four nodes selected at random:</P>
  796. <P><code>&lt;SCRIPT LANGUAGE="javascript"&gt;<br>
  797. link(select("random", someNodes), "random link")<br>
  798. &lt;/SCRIPT&gt;</code></P>
  799. <P>Arrays of other types of items may be created for use with multi-parameter
  800. selection or evaluation functions.</P>
  801. <P>&nbsp;</P>
  802. <h3><a name="Optimizing_Performance"></a>6. Optimizing Performance</h3>
  803. <P><code>fileExtension = &quot;htm|html&quot;</code></P>
  804. <P>By default, the system expects node names to end with the extension &quot;<i>.html</i>&quot;
  805. and treats &quot;<i>.htm</i>&quot; extensions as exceptions. If most or all
  806. of your HTML filenames end with the &quot;<i>.htm</i>&quot; extension, you can
  807. gain a slight increase in both performance and the capacity of the history record
  808. by adding the following line to <i>config.js</i>:</P>
  809. <P><code>fileExtension = &quot;htm&quot;</code></P>
  810. <P>The default setting is:</P>
  811. <P><code>fileExtension = &quot;html&quot;</code></P>
  812. <P>This <code>fileExtension</code> variable has no effect if you are using <a href="#Large_Hypertexts">Short
  813. IDs</a>.</P>
  814. <P>&nbsp;</P>
  815. <h3><a name="Automatic_Execution"></a>7. Automatic Function Execution</h3>
  816. <P><code>executeAfterLoading()</code></P>
  817. <P>If you wish to execute a particular function every time any node is loaded,
  818. you can declare the <code>executeAfterLoading()</code> function in the <i>config.js</i>
  819. file. This function will be executed every time <i>connect.js</i> is loaded.
  820. Because it is executed after the system files are loaded, it can make use of
  821. any Connection System functions. The function is declared by adding the following
  822. lines to <i>config.js</i>:</P>
  823. <P><code>function executeAfterLoading() {<br>
  824. &nbsp;&nbsp;&nbsp;<i>JavaScript expressions</i> <br>
  825. } </code></P>
  826. <P><code><i>JavaScript expressions</i></code> are the lines of JavaScript code
  827. you wish to execute. The following example updates a Table of Contents page
  828. (<i>contents.htm</i>) in a frame called <i>leftFrame</i> every time a node is
  829. loaded.</P>
  830. <P><code>function executeAfterLoading() {<br>
  831. &nbsp;&nbsp;&nbsp;parent.leftFrame.location = "contents.htm" <br>
  832. } </code></P>
  833. <P>You cannot define parameters for this function.</P>
  834. <P>If you wish to prevent <code>executeAfterLoading()</code> from being executed
  835. on a particular page, add the following lines to the header of that page:</P>
  836. <P><code>&lt;SCRIPT LANGUAGE="JavaScript"&gt;<br>
  837. noExecuteAfterLoading = true<br>

  842. <h3><a name="Conditional_Text"></a>Conditional and Random Text</h3>
  843. <p>Connection Muse lets you add conditional elements to your text using
  844. the <a href="#Conditional_Text_Tool">Conditional Text Tool</a>. These are fragments
  845. of text that are either displayed or not displayed on the page, depending upon
  846. conditions that you specify (such as whether or not a particular node has been
  847. read). You can also create several alternative text fragments and specify conditions
  848. that will determine which of the fragments will be displayed when the node is
  849. read.</p>
  850. <p>You can add random elements to your text by creating several alternative text
  851. fragments and specifying that one of these be selected randomly and displayed
  852. in your page when it is read. This can be done with the <a href="#Random_Text_Tool">Random
  853. Text Tool</a>.</p>
  854. <p>Conditional or random text elements can be any length and can include any HTML
  855. tags, so they can contain graphics, tables, audio elements, or JavaScript. You
  856. can specify as many alternative text fragments as you wish within a random text
  857. element. </p>
  858. <h4><a name="Using_Conditional_Text"></a>When to Use Conditional and Random Text</h4>
  859. <p>Conditional text can alter a text so that it will better fit into multiple
  860. contexts, creating syntactic or narrative transitions as needed. This lets you
  861. provide the reader with more options for rearranging the hypertext in different
  862. ways during a reading.</p>
  863. <p>Conditional text can also make node recurrence more interesting and meaningful.
  864. When reading a hypertext, the reader is likely to periodically encounter nodes
  865. she's already read. Rereading these nodes can be more fruitful for the reader
  866. when something new is revealed in them. Changing a few words in the text when
  867. it is read a second or third time can bring out meanings that were only implied
  868. the first time around. Context-sensitive variant versions of a node can ensure
  869. that reading the node in different contexts (that is preceded by different nodes)
  870. reveals new meaning in it. Different implications of a text passage may be brought
  871. out when it is preceded by different nodes, and subtle conditional alterations
  872. to the text can make these implications more explicit. Random variations can
  873. create a more unpredictable type of variety upon rereading.</p>
  874. <p>It can sometimes be useful to suppress or add certain information conditionally
  875. within a node. If a particular node containing background information about
  876. an event or character has already been read, that information can be omitted
  877. from other nodes by means of conditional text. For example, you could specify
  878. that whenever the name &quot;Mary&quot; first appears in a node, it is preceded
  879. by the phrase &quot;Bob's wife,&quot; unless another node referring to Mary
  880. has already been read, in which case Mary will already have been identified
  881. as Bob's wife.</p>
  882. <p>Conditional text can also be used to create alternative plot lines. For example,
  883. after a reader encounters a node in which Mary is killed, Mary could be eliminated
  884. from subsequent nodes by suppressing some of the text in those nodes. If the
  885. reader never encounters the node containing Mary's death, Mary can continue
  886. to figure in the story until the end.</p>
  887. <p>Adding several random elements within the same node can create interesting
  888. and unpredictable textual juxtapositions, such as those found in Surrealist
  889. or Dadaist writings.</p>
  890. <p>&nbsp;</p>
  891. <h3><a name="Conditional_Links"></a>Conditional Links and MultiLinks</h3>
  892. <p>The Connection System lets you create a wide variety of Conditional Links using
  893. the <a href="#Conditional_Links_Tool">Conditional Links Tool</a>. You can specify
  894. that a Conditional Link is to be activated (that is, made clickable) only if
  895. certain conditions are met, or you can specify that the destination node for
  896. a Conditional Link should vary depending on specified conditions.</p>
  897. <p>To create a simple Conditional Link, you define a link and then specify a condition,
  898. such as whether or not a particular node or a specified number of nodes has
  899. been read. You then specify what will happen if the condition is met or not
  900. met. Generally you will want the link to be displayed and activated if the condition
  901. is met. If the condition is not met, you can substitute an alternative destination,
  902. you can deactivate the link (display it as text that is not clickable), or you
  903. can hide the link altogether.</p>
  904. <p>To create a MultiLink, you specify a number of alternative destination nodes
  905. for the link using the <a href="#MultiLink_Tool">MultiLink Tool</a>. You can
  906. then specify that the destination should be chosen randomly or according to
  907. whether or not certain conditions are met. You can also combine random and conditional
  908. selection, so that a destination is chosen randomly from all nodes that meet
  909. a specified condition (such as all nodes not yet visited by the reader).</p>
  910. <h4><a name="Using_Conditional_Links"></a>When to Use Conditional Links</h4>
  911. <p>Simple Conditional Links can serve many useful purposes. You can deactivate
  912. or hide links that lead to nodes that have already been read. This can be useful
  913. if you want to steer readers to new material but for aesthetic reasons don't
  914. want to use an alternative vlink color for followed links. If you are using
  915. clickable graphics for links, you can specify that an alternative graphic image
  916. be displayed for links that lead to previously read nodes.</p>
  917. <p>Conditional Links can be useful for controlling the reader's access to certain
  918. material. To maintain suspense in a story, you might want to withhold certain
  919. passages (such as the one revealing whodunit in a mystery tale) until most of
  920. the hypertext has been read. You can do this by using Conditional Links as the
  921. reader's only means to get to the restricted passages. The links could then
  922. be hidden or deactivated until a specified number of nodes has been read.</p>
  923. <p>For the sake of coherence and logical development in a narrative, you might
  924. want to ensure that certain widely scattered passages within the hypertext are
  925. encountered in a particular order. You can do this by creating Conditional Links
  926. to the passages, specifying that the links remain hidden or inactive until the
  927. prerequisite nodes have been read. For example, Conditional Links could restrict
  928. access to a node that describes a certain action--this node would be inaccessible
  929. until other nodes had been read that establish the motivation for this action.
  930. </p>
  931. <p>Conditional Links can help with character development. Suppose you want to
  932. ensure the progressive development of a character named Mary. First, you could
  933. categorize all the nodes dealing with Mary as belonging to one of three stages
  934. in her development. Conditional links could then ensure that none of the Stage
  935. 2 nodes are visited until all of the Stage 1 nodes have been read. Similarly,
  936. you could ensure that no Stage 3 nodes are available until all Stage 2 nodes
  937. have been read.</p>
  938. <p>Conditional Links can also implement alternative plot elements in a manner
  939. similar to that described in the section on conditional text. If the reader
  940. encounters a node in which Mary dies, this could deactivate all the links to
  941. nodes in which Mary is depicted as being still alive and activate links to nodes
  942. that deal with the consequences of her death.</p>
  943. <h4><a name="Random_Links"></a>Random Links and Other MultiLinks</h4>
  944. <p>MultiLinks can randomly take the reader to a new destination. This can be useful
  945. if you want to achieve a highly fragmented style along the lines of, say, one
  946. of William Burroughs' &quot;cut-up&quot; novels. MultiLinks can also be used
  947. in a more structured way, as described in the following section on text components.</p>
  948. <p>You can specify the alternative destinations in the MultiLink Tool by entering
  949. the names of all the destination nodes in the Nodes field. If you wish to create
  950. a number of different MultiLinks that use the same set of destination nodes,
  951. it is better to create an <a href="#Item_Arrays">Item Array</a> that contains
  952. the names of all the nodes. Then whenever you create a MultiLink you need only
  953. enter the name of the Item Array in the MultiLink Tool. Item Arrays should also
  954. be used to implement Text Componenets as described in the next section.</p>
  955. <p>&nbsp;</p>
  956. <h3><a name="Text_Components"></a>Text Components and Organic Hypertext</h3>
  957. <p>Connection Muse provides features for handling large-scale structural
  958. elements of a story or poem. You can define the large-scale narrative or thematic
  959. components of your text and then specify parameters for how these text components
  960. should unfold and interact with each other during a reading. In other words,
  961. you can assign behaviors to the important elements of your text.</p>
  962. <p>This component and behavior approach lets you define structure as process and
  963. create what we call <i>organic hypertext</i>. There are two facets to the concept
  964. of organic hypertext:</p>
  965. <ul>
  966. <li>The individual parts of the hypertext contain their own predefined behaviors
  967. for growth so they can unfold during the reading with relative independence
  968. when necessary.</li>
  969. <li>At the same time, these individual parts are able to adapt to the unique
  970. circumstances of a particular reading so that the parts can better serve the
  971. whole</li>
  972. </ul>
  973. <p>Here we provide a brief introduction to components and organic hypertext. For
  974. a more in-depth discussion, see <a href="http://www.wordcircuits.com/connect/ht2000.htm" target="_blank">Toward
  975. an Organic Hypertext</a>.</p>
  976. <h4><a name="What_Are_Components"></a>What Are Text Components?</h4>
  977. <p>Text components are any structural or conceptual elements that are likely to
  978. cohere as distinct entities in the reader's mind during the reading process.
  979. For example, the reader may encounter passages about a particular character
  980. scattered throughout the text. The reader will mentally piece the content of
  981. these passages together to form a conceptualization of that character's personality
  982. and history. Here are some categories of text components, along with some specific
  983. examples of these components that we will use in a demo for a hypothetical story:</p>
  984. <p>Settings of time or place</p>
  985. <ul>
  986. <li>Chicago</li>
  987. <li>New York</li>
  988. </ul>
  989. <p>Characterizations</p>
  990. <ul>
  991. <li>Susan</li>
  992. <li>Jacob</li>
  993. <li>Shirley</li>
  994. </ul>
  995. <p>Plot lines</p>
  996. <ul>
  997. <li>Affair between Susan and Jacob</li>
  998. <li>Susan's childhood</li>
  999. <li>Jacob's sexual abuse of his niece, Shirley</li>
  1000. </ul>
  1001. <p>Themes, unifying metaphors, symbolic elements, and so on</p>
  1002. <ul>
  1003. <li>guilt and atonement</li>
  1004. <li>sexual obsession</li>
  1005. </ul>
  1006. <p>Here is a <a href="diagram.htm" target="_blank">diagram</a> of the text component
  1007. structure of this hypothetical story. Note how some text components are contained
  1008. within others (for example, Susan's childhood is set in New York), while others
  1009. overlap (the theme of sexual obsession overlaps with both Jacob's affair and
  1010. his abuse of his niece).</p>
  1011. <h4><a name="Using_Components"></a>Using Text Components</h4>
  1012. <p>You define a text component by specifying a group of nodes that contain the
  1013. relevant textual material. Components may not always be clear-cut, so the contents
  1014. of different components can overlap with each other--that is, the same nodes
  1015. can be contained within more than one component. The content of components can
  1016. even be changed dynamically by adding or removing nodes during the reading.
  1017. Once components are defined, you determine their behavior. You can then create
  1018. links directly to a text component instead of to an individual node. The component's
  1019. predefined behavior will determine which specific node within the component
  1020. will serve as the link's destination.</p>
  1021. <p>You define the contents of a component by creating an <a href="#Item_Arrays">Item
  1022. Array</a> in your config.js file. The Item Array lists all of the nodes that
  1023. constitute the component, and you can access these nodes as a group by using
  1024. the name of the array.</p>
  1025. <p>The nodes in a component can behave as an ordered or an unordered set. If the
  1026. order of the nodes is governed by a logic of chronology or exposition, you can
  1027. treat the nodes as an ordered sequence. An example of this is a group of nodes
  1028. that relate a particular plot line, such as the affair between Susan and Jacob
  1029. in our hypothetical story. Ordered components are represented as ovals in the
  1030. <a href="diagram.htm" target="_blank">diagram</a>. You can specify that every
  1031. time the reader returns to an ordered component, she is taken to the first unvisited
  1032. node in the sequence. This type of component is called a <i>retentive path,</i>
  1033. and it lets a reader easily return to a narrative thread and pick up where she
  1034. left off.</p>
  1035. <p>If the nodes are clearly connected in content but don't inherently demand a
  1036. particular ordering, they can be treated as unordered. An example of this is
  1037. a group of nodes that contribute to the reader's understanding of a particular
  1038. character, locale, object, or event or simply share a philosophical outlook
  1039. or style of writing. All the nodes that bear upon Susan's personality could
  1040. constitute an unordered component. Unordered components are represented as rectangles
  1041. in the <a href="diagram.htm" target="_blank">diagram</a>. (Note that in the
  1042. diagram the unordered components representing locale contain ordered plot components
  1043. within them. Part of a component can behave as an ordered sequence while the
  1044. rest behaves as unordered.)</p>
  1045. <p>Other more complex behaviors are also possible. For example, particular nodes
  1046. can be included in a component or excluded from it depending on whether all
  1047. or part of some other component has been read. Once a component and its behavior
  1048. are defined, links can be created directly to a component instead of to an individual
  1049. node within the component. The component's behavior will determine which node
  1050. the link leads to.</p>
  1051. <p>In the current version of the system, the behavior of a component must be specified
  1052. every time a link is created. You create links to a component with the <a href="#MultiLink_Tool">MultiLink
  1053. Tool</a>, and you specify the behavior by filling out the fields in the MultiLink
  1054. Tool. In our prototype for a future version, behaviors need be specified only
  1055. once, since they will be stored centrally with the components themselves.</p>
  1056. <h4><a name="Component_Demo"></a>The Component Demo</h4>
  1057. <p>We've created a <a href="demos/components/demo.htm" target="_blank">hypertext
  1058. prototype</a> for part of the hypothetical story referred to above. Note that
  1059. this is just a rough outline for demonstration purposes and not meant to be
  1060. a real piece of fiction. After clicking on the link above to launch the demo,
  1061. you will see the main text window on the right and a component map for navigational
  1062. purposes in a smaller window on the left. The demo text consists of 3 text components,
  1063. which are represented by icons in the component map:</p>
  1064. <ol>
  1065. <li><b>The Affair</b> (between Susan and Jacob) is a sequence of 7 nodes that
  1066. unfold a short chronological plot thread. This is a retentive path.</li>
  1067. <li>The <b>Susan</b> component consists of all the nodes about Susan that don't
  1068. require any chronological ordering. These five nodes merely describe aspects
  1069. of her character and they could be slipped in anywhere within the plot line
  1070. and presented in any order. This is an unordered component.</li>
  1071. <li>The <b>Jacob</b> component is an unordered component of five nodes describing
  1072. Jacob.</li>
  1073. </ol>
  1074. <p>All the links in both windows of this demo are made directly to one of these
  1075. three components, and the component's behavior determines the exact destination
  1076. node. All of the links to <b>The Affair</b> lead to the first unvisited node
  1077. in the sequence. All of the links to <b>Susan</b> or <b>Jacob</b> lead to a
  1078. randomly selected unvisited node in the respective component. Once all of a
  1079. character's nodes have been read, previously visited nodes are presented instead
  1080. of new nodes.</p>
  1081. <p>If you wish, you can read all the text by simply clicking repeatedly on the
  1082. 3 icons in the map. These icons shrink in proportion to the amount of text within
  1083. the component that has been read, and moving the mouse pointer over an icon
  1084. shows the percentage of the component read. You can also navigate by following
  1085. links in the text itself.</p>
  1086. <p>Clicking on the <b>Susan</b> or <b>Jacob </b>icon or a link on a character's
  1087. name in the text always yields new material about that character, as long as
  1088. new material is available. This guarantees that a link to a character from anywhere
  1089. in the hypertext will always let you continue to flesh out your knowledge of
  1090. that character and allow you to keep moving forward with the reading.</p>
  1091. <p>After reading several Susan or Jacob nodes, you can return to the story line
  1092. at any time by clicking on either <b>The Affair</b> in the map or &quot;return
  1093. to the steamy stuff&quot; in the text. This lets you resume the story line exactly
  1094. where you left off, no matter where you are in the hypertext.</p>
  1095. <p>The way these links function is an example of allowing the different parts
  1096. of the text to grow independently, one of the goals of organic hypertext. This
  1097. approach makes for a very smooth reading experience. In this short hypertext
  1098. the chances of prematurely looping (that is, encountering previously read material)
  1099. and the need for backtracking to find new material are virtually eliminated,
  1100. even if the reader doesn't use the map. This wouldn't be the case if all the
  1101. links in this work were static and fixed. It is easier for the reader to achieve
  1102. closure in the reading, since it's always clear what remains to be read. The
  1103. component map also makes it much clearer to the reader how she is interacting
  1104. within the large-scale structure of the text.</p>
  1105. <h4> <a name="Complex_Approaches"></a>More Complex Approaches</h4>
  1106. <p> In a larger, more complex hypertext a component map, retentive paths, and
  1107. other Connection System elements can be even more valuable for the reader. Their
  1108. use may also become more complex than in our component demo. Suppose you were
  1109. to implement all of the components you see in our <a href="diagram.htm" target="_blank">component
  1110. diagram</a> and then add some new ones. You might then want to control the reader's
  1111. access to material by manipulating links in the text and on the map. You might
  1112. want the map to dynamically hide or display some components, rather than presenting
  1113. them all at once. For example, a component might appear on the map only after
  1114. the reader has already encountered it through links in the text. You might not
  1115. want to give the reader access to Jacob's sexual abuse until she's read some
  1116. background material about Jacob or Shirley.</p>
  1117. <p> You might not want the reader to be able to read through the entire Affair
  1118. sequence without interruption; you might want to create suspense by withholding
  1119. the last node or two until a lot of other material in the hypertext has been
  1120. read. You may want the reader to be able to read a plot thread by jumping around
  1121. in it occasionally and encountering some events out of order. You might feel
  1122. the need to use mutually exclusive alternative text elements, such as different
  1123. outcomes for a single plot line. You may decide to combine certain components
  1124. or exclude nodes from a component under certain circumstances. All of these
  1125. things are possible with the system. They are examples of the individual parts
  1126. of the text adapting themselves to serve the needs of the whole, the second
  1127. goal of organic hypertext</p>
  1128. <p>&nbsp;</p>
  1129. <h3><a name="Recognized_Problems" id="Recognized_Problems"></a>Recognized Problems</h3>
  1130. <p><b>Pop-up Text</b></p>
  1131. <p>In Netscape Navigator, pop-up text doesn't work properly when connected to
  1132. text that is centered or placed in tables.</p>
  1133. <p>In Internet Explorer, pop-up text doesn't wrap properly when it reaches the
  1134. edge of the window. This may cause some text to be cut off.</p>
  1135. <p>In Internet Explorer, when pop-up text is added to a link or to hot text presented
  1136. with the display() function, any space inserted after the link or the hot text
  1137. is not displayed. This problem does not occur if pop-up text is not used. For
  1138. example, this code:</p>
  1139. <p><code>Place your mouse pointer<br>
  1140. <br>
  1141. &lt;script language="JavaScript"&gt;<br>
  1142. text = "here"<br>
  1143. popupText = "this is the pop-up text"<br>
  1144. display(text)<br>
  1145. &lt;/script&gt;<br>
  1146. <br>
  1147. to view the pop-up text. </code></p>
  1148. <p>should be displayed like this:</p>
  1149. <p>Place your mouse pointer here to view the pop-up text.</p>
  1150. <p>Instead it is displayed like this:</p>
  1151. <p>Place your mouse pointer hereto view the pop-up text. [no space between &quot;here&quot; and &quot;to&quot;] </p>
  1152. <p>Here is a workaround for the problem:</p>
  1153. <p><code>Place your mouse pointer<br>
  1154. <br>
  1155. &lt;script language="JavaScript"&gt;<br>
  1156. text = "here"<br>
  1157. popupText = "this is the pop-up text"<br>
  1158. display(text)<br>
  1159. &lt;/script&gt;&amp;nbsp;to<br>
  1160. <br>
  1161. view the pop-up text.</code></p>
  1162. <p><b>Opening First Page in New Window</b></p>
  1163. <p>The connect.js library file may not load properly when a Connection System
  1164. page is opened in a new browser window by right-clicking on a link and selecting &quot;Open
  1165. in new window.&quot; To avoid this problem, it is best not to use Connection
  1166. System functions in the opening page of a hypertext, since a reader may open
  1167. this page in a new browser window when following a link to it from another
  1168. Web site.</p>
