#!/usr/bin/python3 r""" Bot to upload pages from a text file. This bot takes its input from the UTF-8 text file that contains a number of pages to be put on the wiki. The pages should all have the same beginning and ending text (which may not overlap). The beginning and ending text is not uploaded with the page content by default. As a pagename is by default taken the first text block from the page content marked in bold (wrapped between ''' and '''). If you expect the page title not to be present in the text or marked by different markers, use -titlestart, -titleend, and -notitle parameters. Specific arguments: -file:xxx The filename we are getting our material from, the default value is "dict.txt" -begin:xxx The text that marks the beginning of a page, the default value is "{{-start-}}" -end:xxx The text that marks the end of the page, the default value is "{{-stop-}}" -include Include the beginning and end markers to the page -textonly Text is given without markers. Only one page text is given. -begin and -end options are ignored. -titlestart:xxx The text used in place of ''' for identifying the beginning of a page title -titleend:xxx The text used in place of ''' for identifying the end of the page title -notitle Do not include the page title, including titlestart and titleend, to the page. Can be used to specify unique page title above the page content -title:xxx The page title is given directly. Ignores -titlestart, -titleend and -notitle options -nocontent:xxx If the existing page contains specified statement, the page is skipped from editing -noredirect Do not upload on redirect pages -summary:xxx The text used as an edit summary for the upload. If the page exists, standard messages for prepending, appending, or replacement are appended after it -autosummary Use MediaWiki's autosummary when creating a new page, overrides -summary -minor Set the minor edit flag on page edits -showdiff Show difference between current page and page to upload, also forces the bot to ask for confirmation on every edit If the page to be uploaded already exists, it is skipped by default. But you can override this behavior if you want to: -appendtop Add the text to the top of the existing page -appendbottom Add the text to the bottom of the existing page -force Overwrite the existing page It is possible to define a separator after the 'append' modes which is added between the existing and the new text. For example a parameter -appendtop:foo would add 'foo' between them. A new line can be added between them by specifying '\n' as a value.
