| 43 | /** | |
| 44 | * | |
| 45 | * | |
| 46 | * This is a "drop-in" replacement for the standard TemplateProvider in the | |
| 47 | * WebMacro distribution. The primary benefit is to allow a template to be loaded | |
| 48 | * by a variety of means, without requiring an absolute path. This should make | |
| 49 | * applications more portable. | |
| 50 | * | |
| 51 | * <h3>TemplatePath</h3> | |
| 52 | * | |
| 53 | * <i>TemplatePath=path1[;path2;....]</i> | |
| 54 | * <p> | |
| 55 | * Each path should be a full URL specification or one of the special cases | |
| 56 | * listed below. If the path cannot be interpreted, it will be tried as file:path | |
| 57 | * | |
| 58 | * <h3>Special cases</h3> | |
| 59 | * | |
| 60 | * <ul> | |
| 61 | * <li><i>TemplatePath=classpath:/templates</i> | |
| 62 | * Template will be loaded from the classpath. Each directory on the | |
| 63 | * classpath will be tried in turn to locate the template. | |
| 64 | * | |
| 65 | * <li><i>TemplatePath=ignore:</i> | |
| 66 | * Don't use the template path. All templates will be referenced | |
| 67 | * explicitly as full URL's. A common case would be to generate a base URL | |
| 68 | * at runtime (e.g., from ServletContext.getResource("/") in JSDK 2.2+) and to | |
| 69 | * prepend this to the template path. | |
| 70 | * | |
| 71 | * <li><i>TemplatePath=context:</i> | |
| 72 | * reserved for future use (specifically for finding templates with a | |
| 73 | * servlet context) | |
| 74 | * </ul> | |
| 75 | * | |
| 76 | * <h3>Locale support</h3> | |
| 77 | * | |
| 78 | * There is a limited locale based implemention here. Template paths can contain | |
| 79 | * a string of the form {_aaa_bbb....} which will usually correspond to a | |
| 80 | * locale such as en_GB. | |
| 81 | * Thus <i>load("template{_en_GB}.wm")</i> will look for | |
| 82 | * <ul> | |
| 83 | * <li>template_en_GB.wm</li> | |
| 84 | * <li>template_en.wm</li> | |
| 85 | * <li>template.wm</li> | |
| 86 | * </ul> | |
| 87 | * | |
| 88 | * in that order, returning the first one that exists. This is implemented so that | |
| 89 | * requests for template_en_GB.wm & template_en_US.wm will both return the same template | |
| 90 | * template_en.wm assuming only the latter exists. In other words, the template is | |
| 91 | * only parsed once. | |
