user:js/markZeroEdits

From Wikipedia, the free encyclopedia

Script highlights zero size collapsed edits (usually simple vandalism reversions) in Watchlist and Recent Changes.

21:35	Article1 (3 changes) . . (+750) . . (Page history) [UserA‎; UserB‎; UserC]
21:35	Article2 (2 changes) . . (0) . . (Page history) [10.1.2.3‎; ClueBot‎]
21:34	Article3 (diff; hist . . (-91) . . UserD (Talk I contribs)

Note that multiple collpased edits appear in Recent Changes only with «Enhanced Recent Changes» Preferences option, and also in Watchlist with «Expand Watchlist» option.

[edit] How it works

The script analyzes single edits within collapsed edit.

Zero size collapsed edit is considered a valid revert, and marked with revert-edit class, if:

• there are one or more edits by one user
• and then one edit by another user
• and this last edit has a proper "rever/undo" edit summary

Otherwise collapsed edit is marked with zero-edit class.

[edit] Additional detection parameters

• mzTrustUnregRv: trust reverts by unregs, default is false
• mzTrustSelfRv: trust users' self-reverts, default is false
• mzRevertRegExp: RegExp for proper revert summary, default is /^(BOT[ -]*)?Reverted|^Reverting|^Undid revision /

[edit] Behaviour parameters

• mzMoveReverts: move "valid" reverts to the bottom of the day, default is false.

• mzCSS: CSS that actually highlights zero edits according to classes above, default is:

mzCSS = 'table.revert-edit * {color:#777799}' //mark reverts with blue-gray color
+'table.revert-edit td {text-decoration: line-through}' //and strike-through
+'table.zero-edit * {color:#777799}' //mark other zero edits with blue-gray color

If you use FireFox or Opera, you might want to use opacity instead of the grayish color, e.g. table.revert-edit {opacity: 0.3}

[edit] Installation

Call the script on pages where you want it.

For example, for Watchlist only, add this to your monobook.js (or other appropriate subpage depending on your skin in Preferences):

//[[user:js/markZeroEdits]]: highlight zero size collapsed edits
if (wgCanonicalNamespace=='Special' && wgCanonicalSpecialPageName=='Watchlist')
 importScript('user:js/markZeroEdits.js')

For Watchlist and Recent Changes, with some additional parameters:

//[[user:js/markZeroEdits]]: highlight zero size collapsed edits
mzMoveReverts = true
mzTrustSelfRv = true
if (wgCanonicalNamespace=='Special' 
 && (wgCanonicalSpecialPageName=='Watchlist' || wgCanonicalSpecialPageName=='Recentchanges'))
 importScript('user:js/markZeroEdits.js')
