Selector to omit templates that don't have a template file?

[nghi]

Just wondering if this exist...?

$pages->find("select all templates that don't have an existing template file");
$page->children("same sort of selector top");

It doesn't. Whether a template file matching the name of the template (or the alternative name in the template config) is in fact present in the file system isn't stored in the database.

You could assemble a list of all templates without file and put that into a selector though:

$missing = array();
foreach($templates->find("flags!={template::flagSystem}") as $tpl) {
    if(! $tpl->filenameExists()) $missing[] = $tpl->name;
}
// Now you can get all pages with missing template file:
$pages->find("template=" . implode("|", $missing));
// Or just children
$page->children("template=" . implode("|", $missing));

Sorry, just stumbled across that older post searching for an answer regarding templates selectors...

I'm looking for a method to select all templates except system templates.

This part from your code above doesn't work here:

$templates->find("flags!={template::flagSystem}")

it could only get it to work like this:

$templates->find('flags!=' . Template::flagSystem)

But what's more important is: "flags" is a bitmask value, is it OK to simply compare it in a selector?

Flags are only for internal use. You most likely cannot use them in selectors. Also you don't need to try to be efficient when selecting templates, as all templates are loaded as part of the processwire bootstrapping process, so you can simply iterate $templates and select only non system templates without using a selector. Everything's in memory anyways.

In Template context, is (currently) is, since the only flag currently defined for templates is the system flag. But @LostKobrakai is correct that iterating $templates isn't really a hardship (and likely faster anyway since there are no selectors parse).

Ok, thanks! Solved it like this:

/**
 * Get all templates except system templates (name => label)
 * 
 * @return WireArray $templates
 * 
 */
public function getTemplates() {
    $templates = new WireArray();
    foreach ($this->wire('templates') as $t) {
        if (!($t->flags & Template::flagSystem)) {
            $templates->add($t);
        }
    }

    return $templates;
}
