GluePlugin

Description

This plugin will help you to write readable markup (TWikiMarkup, HMTL, ...) within TWiki by allowing tags and arguments to be formatted on multiple lines. This is done by removing whitespaces surrounding tilde characters at the beginning of a line and recombine consecutive lines again. Basically, there are two ways of glueing and recombining lines by either removing all whitespaces between two lines using %*~~ or by removing all whitespaces and separateing lines with a single space using %~~~. There's a helper character sequence %~~ that prevents the TWiki engine to interprete tags before the GluePlugin could reformat the text. In addition there's a glue sequence #~~ to insert comments within a TWikiMarkup expression.

While these glue sequences might feel strange at the beginning they help you to format and recognize your markup and make it more readable. That way you will be able to format a TWikiApplications that looked like this

%SEARCH{"..." type="query" header="<table width="100%" border="5px"><thead><tr><th>Name</th><th>Description</th><th>Date</th></tr></thead>" format="<tr><th>$formfield(Name)</th><th>$summary</th><th>$createdate</th></tr>" footer="</table>"}%

somewhat like this

#~~ #################################
#~~ # This is my new TWikiApplication
~~~
%~~ SEARCH{
#~~ #################################
#~~ # this is the search expression
~~~   "..."
~~~
~~~   type="query"
~~~
#~~ #################################
#~~ # this is the header of the result table
~~~ 
~~~   header="
~~~      <table
~~~        width="100%"
~~~        border="5px"
~~~      >
~~~      <thead>
~~~        <tr>
~~~          <th>Name</th>
~~~          <th>Description</th>
~~~          <th>Date</th>
~~~        </tr>
~~~      </thead>"
#~~ #################################
#~~ # every row will be formatted like this
~~~
~~~   format="
~~~      <tr>
~~~        <th>$formfield(Name)</th>
~~~        <th>$summary</th>
~~~        <th>$createdate</th>
~~~      </tr>"
#~~ #################################
#~~ # and finally we close this html table
~~~
~~~   footer="</table>"
~~~ }%
#~~ #################################
#~~ # sure we could have used 
#~~ # | TWikiTables | as well |
#~~ # but these aren't robust against newlines
#~~ # in the $summary field
#~~ #################################

Syntax

The <space> is a literal whitespace blank. The ~~~<space> and *~~<space> sequences are recognized only at the beginning of a line, whereas the %~~<space> escape sequence might appear everywhere. The basic anatomy of writing a TWiki tag using the GluePlugin is exemplified by

%~~ TAG{
~~~ key="
*~~      hello
~~~      world
*~~ "
~~~ }%

%<nop>TAG{ key="hello world" }%
