The URL where the data is available. The content will be passed to the
Because of the various way the data can be made available on the web and can be used in Acme::MetaSyntactic, this scheme has evolved to support several cases:
Single source URL:
Multiple source URL:
For themes with categories, its possible to attach a URL for each category:
In the case where the source is an array or a hash reference, an extra case is supported, in case the source data can only be obtained via a POST request. In that case, the source should be provided as either:
A reference to a subroutine that extracts a list of items from a string.
The string is meant to be the content available at the URL stored in
the source key.
The coderef may receive an optional parameter corresponding to the name of the category (useful if the coderef must behave differently depending on the category).
As an ancestor, this class adds the following methods to an Acme::MetaSyntactic theme:
remote_list() Returns the list of items available at the remote source, or an empty list in case of error. has_remotelist() Return a boolean indicating if the source key is defined (and therefore if the theme actually has a remote list). source() Return the data structure containing the source URLs. This can be quite different depending on the class: a single scalar (URL), an array reference (list of URLs) or a hash reference (each value being either a scalar or an array reference) for themes that are subclasses of Acme::MetaSyntactic::MultiList. sources( [ $category ] ) Return the list of source URL. The $category parameter can be used to select the sources for a sub-category of the theme (in the case of Acme::MetaSyntactic::MultiList).
$category can be an array reference containing a list of categories.
extract( $content ) Return a list of items from the $content string. $content is expected to be the content available at the URL given by source().
The Acme::MetaSyntactic::RemoteList class also provides a few helper subroutines that simplify the normalisation of items:
tr_nonword( $str ) Return a copy of $str with all non-word characters turned into underscores (_). tr_accent( $str ) Return a copy of $str will all iso-8859-1 accented characters turned into basic ASCII characters. tr_utf8_basic( $str ) Return a copy of $str with some of the utf-8 accented characters turned into basic ASCII characters. This is very crude, but I didnt to bother and depend on the proper module to do that.
