Render List Plugin

Render bullet lists in a variety of formats

Syntax Rules

RENDERLIST Macro

• 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 DocumentGraphics icon can be used as well:
    • %ICON{name}% Followed by normal bullet text

Themes

Themes are defined by setting a preference called RENDERLISTPLUGIN_<SOMETHING>_THEME (for example, RENDERLISTPLUGIN_THREAD_THEME ) and contain a comma-delimited list of render type and parameters. The default themes are:

Theme	Render type
THREAD	tree, 1
ORG	icon, 0, 16, 16, , , , ,
GROUP	icon, 0, 16, 16, , , , ,
EMAIL	icon, 0, 16, 16, , , , ,
TREND	icon, 0, 16, 16, , , , ,
FILE	icon, 0, 16, 16, , , , ,

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. "Extensions Operation and Maintenance" Tab -> "Install, Update or Remove extensions" Tab. Click the "Search for Extensions" button. Enter part of the extension name or description and press search. Select the desired extension(s) and click install. If an extension is already installed, it will not show up in the search results.

You can also install from the shell by running the extension installer as the web server user: (Be sure to run as the webserver user, not as root!)

cd /path/to/foswiki
perl tools/extension_installer <NameOfExtension> install

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See https://foswiki.org/Support/ManuallyInstallingExtensions for more help.

• Test if the installation was successful: See if above examples work
