Syntax Rules

RENDERLIST Variable

• Place a %RENDERLIST{ <parameters> }% before any bullet list
  • The lists can be handcrafted, generated by another Plugin, a %TOC%, or the result of a FormattedSearch
• Supported parameters:

  "name" or theme="name"	Select a rendering theme
  focus="any text"	Focus list on a bullet with specified text
  depth="2"	Remove bullets with an indent greater then the depth. The depth is relative to the highlighted bullet in case focus is specified

• Rendering themes can be defined by <name>_THEME Plugin settings
  • Each theme is defined by a comma separated list containing the render type and parameters required by that render type
  • There are different render types; this initial Plugin version has tree and icon render types
• Format of the tree render type:
  • Set <name>_THEME = tree, <0/1 flag to suppress/show lines of first level>
• Format of the icon render type:
  • Set <name>_THEME = icon, <0/1 flag to suppress/show lines of first level>, <icon width>, <icon height>, <spacer graph>, <T-line graph>, <I-line graph>, <L-line graph>, <icon image>
  • To define new Icon themes, attach images to this Plugin topic and set the parameters accordingly
• Focus bullet list:
  • Search bullet list for text. If a bullet is found:
    1. Highlight text and remove [[][]] links on bullet where text is found
    2. Reduce bullet list to show only its parents and children
  • This is useful to maintain one large bullet list with links to team pages, representing the organization of a company. Each team page can INCLUDE the bullet list with focus set to itself.

Bullets

• Use regular * bullets
• Start with level one
  • Increase indentation only one level at a time
    • Like this
• Decreasing indentation many levels at a time is OK
• Wrap long text with continuation lines, the Plugin does not do that for you
  Align continuation lines with leading spaces like this
• You can specify an icon for a bullet of render type tree or icon:
  • Attach the icon to this Plugin topic, e.g. myicon.gif, or
  • Use one of the existing icons: globe.gif, home.gif, virtualhome.gif, group.gif, persons.gif, virtualpersons.gif, person.gif, virtualperson.gif, email.gif, trend.gif, folder.gif, folders.gif, file.gif, files.gif, doc.gif, image.gif, pdf.gif, ppt.gif, sound.gif, xls.gif, zip.gif, see.gif
  • Refer to an attached icon at the beginning of the bullet with:
    • icon:myicon Followed by normal bullet text
  • Any TWikiDocGraphics icon can be used as well:
    • %ICON{name}% Followed by normal bullet text
