Extension:External Data/cs

Rozšíření External Data umožňuje stránkám MediaWiki načítat, filtrovat a formátovat strukturovaná data z jednoho nebo více zdrojů. Tyto zdroje mohou zahrnovat externí adresy URL a služby SOAP, běžné wiki stránky, nahrané soubory, soubory na místním serveru, databáze, adresáře LDAP a výstup lokálních programů.

The extension defines the following :
 * Data retrieval and handling functions, which set local variables and then display or store them:
 * #external_value - displays the value of any such variable.
 * #for_external_table - cycles through all the values retrieved for a set of variables, displaying the same "container" text for each one.
 * #display_external_table - cycles through all the values retrieved for a set of variables, displaying each "row" using a template.
 * #format_external_table - available only if Cargo is installed. Formats the retrieved external data the same way as #cargo_query.
 * #store_external_table - cycles through a table of values, storing them as semantic data via the Semantic MediaWiki extension, by mimicking a call to SMW's #subobject function for each row.
 * In the Legacy mode the extension also defines data retrieval functions, which set local variables available with wikipage scope that can later be displayed using the above functions:
 * #get_external_data - retrieves data from various sources, thus replacing any of the below parser functions, and assigns it to variables that can be accessed on the page.
 * #get_web_data - retrieves CSV, GFF, JSON, YAML, XML, HTML, ini, or free-form data from a URL and assigns it to variables that can be accessed on the page.
 * #get_soap_data - retrieves data from a URL via the SOAP protocol.
 * #get_file_data - retrieves data from a file on the local server, in the same formats as #get_web_data.
 * #get_db_data - retrieves data from a database.
 * #get_ldap_data - retrieves data from an LDAP server.
 * #get_program_data - retrieves data returned by a program run server-side.
 * #get_inline_data - parses data passed to it, in the same formats as #get_web_data.
 * and also #clear_external_data that erases the current set of retrieved data or only some variables.

It also defines a Lua function  that retrieves data and returns it as Lua table.

In the Legacy mode, the following additional Lua functions are also defined (there is one-to-one correspondence between parser functions retrieving data and Lua functions evident from their names):



In tag emulation mode, the wiki site administrator can define additional parser tags.

This version of the External Data extension requires MediaWiki 1.33+.
