Define aliases which will be replaced with arbitrary strings automatically


This plugin allows you to create arbitrary word aliases. If you write down a word that has a defined alias, it will then be replaced with the given text string. If that string is a string of the format <web>.<topic> it will be replaced by an appropriate link.


Configuration of this plugin is done by writing your aliases into a specific topic, the WebAliases defining the WebAliases for the current web. Site-wide aliases can be defined in SiteAliases. Definitions are looked up in the given order:

  1. current topic
  2. current web's WebAliases
  3. Main.SiteAliases

Aliases are applied when saving a topic. The original form is encoded together with the replacement. The reverse operation is done before editing the topic.


This is the list of tags defined by this plugin.
Name Description
%ALIASES% display all aliases
%ALIASES{regex="on"}% display also the regular expression to match the alias
%ALIASES{"<topic>" merge="on,off"}% use aliases defined in <topic> by either merging or redefining the set of current aliases
%ALIAS{name="..." value="..." [regex="..."]}% defines an alias using regex to find it; if regex is not specified it defaults to the alias' name
%UNALIAS% delete all aliases
%UNALIAS{name="..."}%,%UNALIAS{"..."}% deletes one alias

The regex parameter in the %ALIAS{...}% tag might contain the two variables $start and $stop that help to match the boundaries of an alias consisting of non-alphabetic characters. Some textile examples:

%ALIAS{name="''" regex="$start''$stop" value="&rdquo;"}%
%ALIAS{name="``" regex="$start``$stop" value="&ldquo;"}%
%ALIAS{name="--" regex=" -- " value=" &mdash; "}%
%ALIAS{name="(c)" regex="$start\(c\)$stop" value="&copy;"}%
%ALIAS{name="(r)" regex="$start\(r\)$stop" value="&reg;"}%
%ALIAS{name="(tm)" regex="$start\(tm\)$stop" value="&trade;"}%
%ALIAS{name="..." regex="$start\.\.\.$stop" value="&hellip;"}%
%ALIAS{name=",," regex="$start,,$stop" value="&bdquo;"}%
%ALIAS{name="1/2" regex="$start1/2$stop" value="&frac12;"}%
%ALIAS{name="1/4" regex="$start1/4$stop" value="&frac14;"}%
%ALIAS{name="3/4" regex="$start3/4$stop" value="&frac34;"}%

Defined Aliases

%ALIAS{name="TESTLINK" value="System.WebHome"}% %ALIAS{name="TESTALIAS" value="yes"}% %ALIAS{name="rtfm" value="read the fine manual"}% %ALIASES%
