If empty, no Flattr buttons are generated at all. +# - flattrthing_defaultuser: sets the default user that owns the Flattr things +# which are created by the auto-submit buttons. +# +# Also, the plugin adds the flattrthing directive, which allows you to customize +# the behaviour for one page. It knows the following parameters: +# - id: the Flattr thing ID (like in http://flattr.com/thing/12341234). If you +# specify this option, a button with a thing URL is generated instead of an +# auto-submit button. This allows you to link to things which already exist +# by the time you create your page. +# - user: a Flattr username that owns the thing created by the generated +# auto-submit button. This parameter has no effect when an ID is specified, +# since in this case, the owner is already known to Flattr. +# +# This plugin sets the following template variables which your templates should +# process and generate the according buttons with the right URLs: +# - FLATTR_ENABLE: contains a truthful value if the page matches the pagespec +# configured with flattrthing_pagespec. You can use it with TMPL_IF to +# generate code specific to pages which have a Flattr button. +# - FLATTR_THING_ID: if a thing ID was specified with the flattrthing directive, +# this variable contains the ID that was given in the directive. +# - FLATTR_THING_ID_SET: contains a thurthful value if FLATTR_THING_ID is set. +# - FLATTR_USER: contains the username that was specified with the flattrthing +# directive, or if that was not the case, the username that was configured +# with flattrthing_defaultuser in your setup file. +# - FLATTR_THING_URL: contains the full URL to the page. + +package IkiWiki::Plugin::flattrthing; + +use warnings; +use strict; +use IkiWiki 3.00; + +sub import { + hook(type => "getsetup", id => "flattrthing", call => \&getsetup); + hook(type => "scan", id => "flattrthing", call => \&scan); + hook(type => "preprocess", id => "flattrthing", call => \&preprocess); + hook(type => "pagetemplate", id => "flattrthing", call => \&pagetemplate); +} + +sub getsetup () { + return + plugin => { + safe => 1, + rebuild => undef, + section => "widget", + }, + flattrthing_pagespec => { + type => "pagespec", + example => "!*/Discussion", + description => "Pages on which flattr button should be inserted.
