I get the following error when building my wiki

Argument "\x{3c}\x{54}..." isn't numeric in numeric eq (==) at /usr/share/perl5/IkiWiki.pm line 2547.
Argument "\x{3c}\x{54}..." isn't numeric in numeric eq (==) at /usr/share/perl5/IkiWiki.pm line 2547.

that line corresponds to

sub match_creation_year ($$;@) {
if ((localtime($IkiWiki::pagectime{shift()}))[5] + 1900 == shift) { <-- this one
    return IkiWiki::SuccessReason->new('creation_year matched');
}

A git bisect shows that the offending commit introduced this hunk

The lines which feature creation_year() are most likely the culprits. That would explain why the error was repeated twice, and would tally with the file in templates/ being rendered, rather than the inclusionists.

A workaround is to move the template outside of the srcdir into the external templates directory and include the file suffix when using it, e.g.

[[!template  id=all_entry.tmpl year=2010 current=true]]

I believed (until I tested) that the if directive, with the included() test, would be an option here, E.g.

[[!if  test="included()" then="""
...template...
""" else="""
Nothing to see here.
"""]]

However this doesn't work. I assume "included" in this context means e.g. via an inline or map, not template trans-clusion. -- Jon

Sorry Joey, I'll make sure to reproduce stuff against master in future. Jon
