Detailed Description

This template loader works by traversing a list of directories to find templates. Directories are checked in order, and the first match hit is parsed and returned.

loader->setTemplateDirs({
    "/home/user/app/templates",
    "/usr/local/share/app/templates"
});
engine->setTemplateLoader( loader );
 
// This will try /home/user/app/templates/mytemplate.html
// followed by /usr/local/share/app/templates/mytemplate.html
engine->loadByName( "mytemplate.html" );

Additionally, a themeName may be set on the template loader, which will be appended to search paths before the template name.

loader->setTemplateDirs({
  "/home/user/app/templates" <<
  "/usr/local/share/app/templates"
});
loader->setTheme( "simple_theme" );
engine->setTemplateLoader( loader );
 
// This will try /home/user/app/templates/simple_theme/mytemplate.html
// followed by /usr/local/share/app/templates/simple_theme/mytemplate.html
engine->loadByName( "mytemplate.html" );

Media URIs may be retrieved for media relative to the directories searched queried for templates.

loader->setTemplateDirs({
  "/home/user/app/templates",
  "/usr/local/share/app/templates"
});
loader->setTheme( "simple_theme" );
engine->setTemplateLoader( loader );
 
// This will try /home/user/app/templates/simple_theme/logo.png
// followed by /usr/local/share/app/templates/simple_theme/logo.png
// and return the first one that exists.
engine->mediaUri( "logo.png" );

The template files loaded by a %**FileSystemTemplateLoader** must be UTF-8 encoded.
