| 82 <h3>Loading Templates</h3> | |
| 83 <p>The <code>#load</code> directive may be used to load additional | |
| 84 templates, e.g. ones containing macro definitions. Note that the loaded | |
| 85 files are standard Chameleon templates and <em>not</em> TinCan <code>.pspx</code> | |
| 86 files (i.e. they cannot contain any header directives); as such, loaded | |
| 87 files must have the standard <var>.pt</var> extension for Chameleon | |
| 88 template files.</p> | |
| 89 <p>In the normal case, typing <code>#load foo.pt</code> will load a file | |
| 90 relative to the same directory as the page containing the <code>#load</code> | |
| 91 directive itself. The loaded template object will be made available as a | |
| 92 template variable matching the file name sans extension (in this case, <samp>foo</samp>). | |
| 93 One can change the name of the variable created by prefixing the file | |
| 94 specification with a variable name followed by an equals sign, | |
| 95 e.g. <code>#load t=foo.pt</code>. If one places the specification inside | |
| 96 angle brackets (e.g. <code>#load <t=foo.pt></code>), loaded files | |
| 97 are searched for in <code>WEB-INF/tlib</code> instead.</p> | |
| 98 <p>Finally, as is allowed for all arguments to header directives, one may | |
| 99 enclose the argument to #load inside single or double quotes and use the | |
| 100 normal Python backslash escaping.</p> | |
| 101 <h3>Using Loaded Macros</h3> | |
| 102 <p>Once a template has been loaded, it will be available as a sub-attribute | |
| 103 of the <var>macros</var> attribute of the associated template object. | |
| 104 E.g.:</p> | |
| 105 <pre>#load foo.pt<br><!DOCTYPE html><br><html><br> <head><br> <title>Macro Example</title><br> </head><body><br> <p metal:use-macro="foo.macros.bar"></p><br> </body><br></html></pre> | |
