tw_get_cached_wikipedia_category_members: Gets members of Wikipedia categories from local cache

Description

Mostly used internally.

Usage

tw_get_cached_wikipedia_category_members(
  category,
  type = "page",
  language = tidywikidatar::tw_get_language(),
  cache = NULL,
  cache_connection = NULL,
  disconnect_db = TRUE
)

Value

If data present in cache, returns a data frame with cached data.

Arguments

category

Title of a Wikipedia category page or final parts of its url. Must include "Category:", or equivalent in other languages. If given, url can be left empty, but language must be provided.

type

Defaults to "page", defines which kind of members of a category are returned. Valid values include "page", "file", and "subcat" (for sub-category). Corresponds to cmtype. For details, see the relevant page of the official documentation.

language

Defaults to language set with tw_set_language(); if not set, "en". Use "all_available" to keep all languages. For available language values, see the dedicated Wikimedia page.

cache

Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with tw_enable_cache() or tw_disable_cache().

cache_connection

Defaults to NULL. If NULL, and caching is enabled, tidywikidatar will use a local sqlite database. A custom connection to other databases can be given (see vignette caching for details).

disconnect_db

Defaults to TRUE. If FALSE, leaves the connection to cache open.
