The <code>GET</code> and <code>SET</code> keywords are actually optional as the parser is smart enough to see them for what they really are (but note the caveat below on using side-effect notation). Thus, you'll generally see: </p> <pre>[% SET foo = 10 %] [% GET foo %]</pre> <p> written as: </p> <pre>[% foo = 10 %] [% foo %]</pre> <p> You can also express simple logical statements as implicit <code>GET</code> directives: </p> <pre>[% title or template.title or 'Default Title' %] [% mode == 'graphics' ? "Graphics Mode Enabled" : "Text Mode" %]</pre> <p> All other directives should start with a keyword specified in UPPER CASE (but see the <code>ANYCASE</code> option). All directives keywords are in UPPER CASE to make them visually distinctive and to distinguish them from variables of the same name but different case. It is perfectly valid, for example, to define a variable called <code>stop</code> which is entirely separate from the <code>STOP</code> directive. </p> <pre>[% stop = 'Clackett Lane Bus Depot' %] The bus will next stop at [% stop %] # variable [% STOP %] # directive</pre> </div> </div> <div class="section"> <div class="head"> <h1 id="Block_Directives" onclick="switch_section(this)" title="Click title to show/hide section content.">Block Directives</h1> <a href="#body" class="top" title="Back up to the top of the page" >Top</a> </div> <div class="body"> <p> Directives such as <code>FOREACH</code>, <code>WHILE</code>, <code>BLOCK</code>, <code>FILTER</code>, etc., mark the start of a block which may contain text or other directives up to the matching <code>END</code> directive. Blocks may be nested indefinitely. The <code>IF</code>, <code>UNLESS</code>, <code>ELSIF</code> and <code>ELSE</code> directives also define blocks and may be grouped together in the usual manner. </p> <pre>[% FOREACH item = [ 'foo' 'bar' 'baz' ] %] * Item: [% item %] [% END %] [% BLOCK footer %] Copyright 2000 [% me %] [% INCLUDE company/logo %] [% END %] [% IF foo %] [% FOREACH thing = foo.things %] [% thing %] [% END %] [% ELSIF bar %] [% INCLUDE barinfo %] [% ELSE %] do nothing... [% END %]</pre> <p> Block directives can also be used in a convenient side-effect notation. </p> <pre>[% INCLUDE userinfo FOREACH user = userlist %] [% INCLUDE debugtxt msg="file: $error.info" IF debugging %] [% "Danger Will Robinson" IF atrisk %]</pre> <p> versus: </p> <pre>[% FOREACH user = userlist %] [% INCLUDE userinfo %] [% END %] [% IF debugging %] [% INCLUDE debugtxt msg="file: $error.info" %] [% END %] [% IF atrisk %] Danger Will Robinson [% END %]</pre> </div> </div> <div class="section"> <div class="head"> <h1 id="Capturing_Block_Output" onclick="switch_section(this)" title="Click title to show/hide section content.">Capturing Block Output</h1> <a href="#body" class="top" title="Back up to the top of the page" >Top</a> </div> <div class="body"> <p> The output of a directive can be captured by simply assigning the directive to a variable. </p> <pre>[% headtext = PROCESS header title="Hello World" %] [% people = PROCESS userinfo FOREACH user = userlist %]</pre> <p> This can be used in conjunction with the <code>BLOCK</code> directive for defining large blocks of text or other content. </p> <pre>[% poem = BLOCK %] The boy stood on the burning deck, His fleece was white as snow. A rolling stone gathers no moss, And Keith is sure to follow. [% END %]</pre> <p> Note one important caveat of using this syntax in conjunction with side-effect notation. The following directive does not behave as might be expected: </p> <pre>[% var = 'value' IF some_condition %] # does not work</pre> <p> In this case, the directive is interpreted as (spacing added for clarity) </p> <pre>[% var = IF some_condition %] value [% END %]</pre> <p> rather than </p> <pre>[% IF some_condition %] [% var = 'value' %] [% END %]</pre> <p> The variable is assigned the output of the <code>IF</code> block which returns <code>'value'</code> if true, but nothing if false. In other words, the following directive will always cause 'var' to be cleared. </p> <pre>[% var = 'value' IF 0 %]</pre> <p> To achieve the expected behaviour, the directive should be written as: </p> <pre>[% SET var = 'value' IF some_condition %]</pre> </div> </div> <div class="section"> <div class="head"> <h1 id="Chaining_Filters" onclick="switch_section(this)" title="Click title to show/hide section content.">Chaining Filters</h1> <a href="#body" class="top" title="Back up to the top of the page" >Top</a> </div> <div class="body"> <p> Multiple <code>FILTER</code> directives can be chained together in sequence.
