The motivation for this plugin was to provide an ++easy way for end users to add information to be used in templates -- ++for example, my C<Blosxom> blog entry template does fancy things with ++the date components of the entry, and there was no easy way to get ++that information into the template. Or if one wants to have a ++different page template for the top level index page than for the rest ++of the pages in the wiki (for example, to only put special content, ++like, say, C<last.fm> play lists, only on the front page). ++ ++This plugin hooks itsef into the C<pagetemplate> hook, and adds ++parameters to the appropriate templates based on the type. For ++example, the following inseted into C<ikiwiki.setup> creates ++C<TMPL_VAR MOTTO>, C<ARRAYVAR>, C<HASHVAR> and C<TOPLVL> which can ++then be used in your templates. The array and hash variables are only ++for completeness; I suspect that the first two forms are all that are ++really required. ++ ++ varioki => { ++ 'motto' => '"Manoj\'s musings"', ++ 'toplvl' => 'sub {return $page eq "index"}', ++ 'arrayvar' => '[0, 1, 2, 3]', ++ 'hashvar' => '{1, 1, 2, 2}' ++ }, ++ ++Please note that the values in the hash must be simple strings which ++are then eval'd, so a string value has to be double quoted, as above ++(the eval strips off the outer quotes). ++ ++=cut ++ ++ ++sub import { #{{{ ++ hook(type => "pagetemplate", id => "varioki", call => \&pagetemplate); ++} # }}} ++ ++ ++=pod ++ ++For every key in the configured hash, the corresponding value is ++evaluated. Based on whether the value was a stringified scalar, code, ++array, or hash, the value of the template parameter is generated on ++the fly. The available variables are whatever is available to ++C<pagetemplate> hook scripts, namely, C<$page>, C<$destpage>, and ++C<$template>. Additionally, the global variables and functions as ++defined in the Ikiwiki documentation ++(L<http://ikiwiki.kitenet.net/plugins/write.html>) may be used. ++ ++=cut ++ ++sub pagetemplate (@) { #{{{ ++ my %params=@_; ++ my $page=$params{page}; ++ my $template=$params{template}; ++ ++ return unless defined $config{varioki}; ++ for my $var (keys %{$config{varioki}}) { ++ my $value; ++ my $foo; ++ eval "\$foo=$config{varioki}{$var}"; ++ if (ref($foo) eq "CODE") { ++ $value = $foo->(); ++ } ++ elsif (ref($foo) eq "SCALAR") { ++ $value = $foo; ++ } ++ elsif (ref($foo) eq "ARRAY") { ++ $value = join ' ', @$foo; ++ } ++ elsif (ref($foo) eq "HASH") { ++ for my $i (values %$foo ) { ++ $value .= ' ' . "$i"; ++ } ++ } ++ else { ++ $value = $foo; ++ } ++ warn "$page $var $value\n"; ++ if ($template->query(name => "$var")) { ++ $template->param("$var" =>"$value"); ++ } ++ } ++} # }}} ++ ++1; ++ ++=head1 CAVEATS ++ ++This is very inchoate, at the moment, and needs testing. Also, there ++is no good way to determine how to handle hashes as values -- ++currently, the code just joins all hash values with spaces, but it ++would be easier for the user to just use an anonymous sub instead of ++passing in a hash or an array. ++ ++=cut ++ ++=head1 BUGS ++ ++Since C<ikiwiki> evals the configuration file, the values have to all ++on a single physical line. This is the reason we need to use strings ++and eval, instead of just passing in real anonymous sub references, ++since the eval pass converts the coderef into a string of the form ++"(CODE 12de345657)" which can't be dereferenced. ++ ++=cut ++ ++=head1 AUTHOR ++ ++Manoj Srivastava <srivasta@debian.org> ++ ++=head1 COPYRIGHT AND LICENSE ++ ++This script is a part of the Devotee package, and is ++ ++Copyright (c) 2002 Manoj Srivastava <srivasta@debian.org> ++ ++This program is free software; you can redistribute it and/or modify ++it under the terms of the GNU General Public License as published by ++the Free Software Foundation; either version 2 of the License, or ++(at your option) any later version. ++ ++This program is distributed in the hope that it will be useful, ++but WITHOUT ANY WARRANTY; without even the implied warranty of ++MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
