This module provides support for more URI providers.
uri: URI provider name (optional, default=module name)
Function for init of modules providing URI functions. Module must define functions {uri}_list and {uri}_get.
NOTE: Any ocurrence of "-" in URI provider part is converted to "_".
Array, which contains all registered URI providers.
Module provides function for: function uri {
Module provides function for: pwiz_fatal "uri called without argument outside init"
Module provides function for: pwiz_array_add uris "$uri"
Module provides function for: declare -a uris
uri: URI
returns: 0: URI exists, 1: URI does not exist
Check, whether specified URI exists.
uri: URI
file: file name to be downloaded to (in case of empty string, backend will choose one, probably last element of path, if last element of path is empty, too, then "uri_index" is used)
Download specified URI to current directory as file.
uri: complete URI
uri_list_callback: callback for found items (can be empty - $pwiz_callback is used instead - probably echo)
Call callback for all available hyperlinks in specified URI.
uri: URI of found hyperlink
uri_type: "list": URI contains sub-URIs (directory, web page), "file": URI is file (downloadable file without links), "link": URI is hyper-reference or alias of different URI, "unknown": unknown type of URI (can be any of previous type)
returns: 0: no action needed, 1: follow this URI
Callback function for uri_list. If it returns 1, list function will suppose, that URI type is a "list" (or "link") and will follow this URI.
NOTE: Real calling of callback is delayed, so back-end can have opened fixed file I/O during call. There is no guarantee of callback order.
uri: complete URI
provider: provider part of URI
domain: domain part of URI
path: path part of URI
returns: 0: URI exists, 1: URI does not exist
Back-end function for URI provider. Check, whether specified URI exists.
uri: complete URI
provider: provider part of URI
domain: domain part of URI
path: path part of URI
file: file name to be downloaded to
Back-end function for URI provider. Download specified URI to current directory as file.
uri: complete URI
provider: provider part of URI
domain: domain part of URI
path: path part of URI
uri_list_callback: callback for found items
Back-end function for URI provider. Call callback for all available hyperlinks in specified URI. Callback function must be called by:
uri_callback uri_list_callback uri uri_type
uri_list_callback: callback for found items
uri: URI of found hyperlink
uri_type: "list": URI contains sub-URIs (directory, web page), "file": URI is file (downloadable file without links), "link": URI is hyper-reference or alias of different URI, "unknown": unknown type of URI (can be any of previous type)
Internal function for {uri}_list back-end of URI provider. this function performs calling of uri_list_callback and does recursive calling, if required.
