ImgPlugin

This is a fairly winky-dink plugin that allows people to use %IMG{"foo.gif"}% instead of using HTML syntax. It allows specification of the standard attributes as well as an optional web=<web> and/or topic=<topic>.

Another small step in the eradication of html in TWiki!

On this page:

Syntax Rules

  • image name is mandatory, web and/or topic optional (defaulting to the current web and topic respectively
  • Supports the img attributes 'align', 'border', 'height', 'width', 'id', and 'class
  • Always puts in an alt tag with a value of '' if not specified. This is per XHTML spec.

Argument Meaning Default Required
name attachment name none yes
web web name of the attachment current web no
topic topic name of the attachment current topic no
alt alternate text tag '' no
caption caption to go with the image none no
captionplacement one of right, left, top, bottom right no

One good addition would be the auto-addition of the image size when possible, since I believe that pages load faster that way. This may require imagemagick, however.

Examples

  • %IMG{"foo.gif"}%
  • %IMG{"foo.gif" topic="ADifferentTopic"}%
  • %IMG{"foo.gif" align="right"}%

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, i.e. %IMGPLUGIN_SHORTDESCRIPTION%

  • One line description, is shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Allows TWiki variable-style insertion of images in topics

  • Debug plugin: (See output in data/debug.txt)
    • Set DEBUG = 0
