Manual:Pywikibot/cosmetic changes.py

cosmetic_changes.py makes little changes in one or several wiki pages that make the source code look cleaner. These changes are not supposed to change the look of the rendered wiki pages.

Before running it on a specific wiki, each sub-module should be reviewed and checked if it is helpful for this wiki.

"
 * fix self interwiki: interwiki links to the site itself are displayed like local links, removing their language code prefix.
 * standardize page footer: makes sure that categories, stars templates for featured articles and interwiki links are put to the correct position. templates and interwiki links are sorted into the right order.
 * clean up links: improves how links are presented by doing the following:
 * replaces underlines by spaces, also multiple underlines.
 * removes unnecessary leading spaces from a title.
 * removes unnecessary trailing spaces from a title.
 * converts URL-encoded characters to unicode.
 * removes unnecessary initial and final spaces from a label.

 * clean up section headers: for better readability of section header source code, puts a space between the equal signs and the title; for example: "==Section title==" becomes "== Section title ==".
 * put spaces in lists: for better readability of bullet list and enumeration wiki source code, puts a space between the * or # and the text.
 * translate and capitalize namespaces: makes sure that localized namespace names are used. Does not change "image" alias on en-wiki or fr-wiki.
 * resolve html entities
 * valid xhtml: tries to make a valid XHTML document, for example, replacing "  " by "

 * remove non breaking space before percent: newer MediaWiki versions automatically place a non-breaking space in front of a percent sign, so it is no longer required to place it manually.
 * fix syntax: correct mediawiki syntax for external links
 * fix HTML: translates some HTML-entities into the corresponding mediawiki syntax; remove unneeded tag.
 * fix style: convert prettytable to wikitable class (de-wiki and en-wiki only).
