Od roku 2017 poskytuje vizuálny editor "vizuálne rozdiely verzií" K týmto sa dá dostať dvoma spôsobmi: počas kontrolovania zmien, pred uložením dokumentu a (beta funkcia) zo štandardnej MediaWiki stránky rozdielov verzií, ku ktorej sa dá dostať zo stránky histórie. V oboch prípadoch sa vizuálne rozdiely zobrazia vedľa bežného dvojstĺpcového rozdielu verzií a užívateľ si medzi týmito dvoma zobrazeniami môže prepínať. These are available in two places in the interface: when previewing changes to the document before the user saves the page, and (as a beta feature) within the standard MediaWiki diff display, accessed from the history page. In both cases, the visual diff shows up alongside the traditional two-column wikitext diff, and the user can toggle between the two displays.

Vizuálne rozdiely majú nad wikitextovými rozdielmi dve hlavné výhody. Prvou je, že redaktori dokážu priamo vidieť rozdiely, ktoré, oni a iný spravili, bez toho aby museli rozumieť wikitextu, čo je užitočné najmä pri prezeraní si zmien grafických objektov ako napríklad tabuliek. Napríklad, pokiaľ sa zmenou z tabuľky vymažú stĺpce, rozdiel vo wikitexte je zložitý na interpretáciu, zatiaľ čo vizuálny rozdiel je pochopiteľný ihneď. The first is that editors can directly see the changes they and others have made without needing to understand wikitext. This is particularly helpful when looking at changes to graphical structures such as tables; for example, if an edit deletes a column from a table, the wikitext diff for it would be hard to understand, while the visual diff would be immediately obvious.

Druhou je, že sa nimi dajú čitateľovi presnejšie ukázať zmeny. Napríklad pokiaľ sa úpravou prehodia dva odstavce (s alebo bez zmeny daných odstavcov), pomocou vizuálnych rozdielov sa dá ihneď určiť čo sa stalo, zatiaľ čo na wikitextových rozdieloch to vyzerá ako keby bol odstavec vymazaný a následne bol pridaný úplne nový odstavec. For example, if an edit swapped two paragraphs (with or without changes to the paragraphs), the visual diff will identify that this is what occurred, while a wikitext diff makes it appear that a paragraph was deleted and an entirely new paragraph was added.

On regular diff pages

Most of the examples and screenshots below are about using visual diffs during page previews when editing. However, VisualEditor's visual diffs can also be used on regular diff pages, on any wiki that has VisualEditor installed. You can see an example of it in use on the English-language Wikipedia here.

For wikis that have VisualEditor, there are several ways to activate this visual diff display:

  • Add the following to LocalSettings.php:
$wgVisualEditorEnableDiffPage = true;
  • If your wiki has a "Beta features" tab within Special:Preferences, and you want to make visual diffs an "opt-in" feature for users, you can add the following to LocalSettings.php:
$wgVisualEditorEnableDiffPageBetaFeature = true;
  • As seen in the Wikipedia example linked above, the visual diff mode can also be activated by simply adding "&visualdiff" to the URL of a diff page.

How it works

 
When you are finished editing the page, type your edit summary and then choose "Skontrolovať zmeny". In visual mode, you will see additions, removals, new links, and formatting highlighted. Other changes, such as changing the size of an image, are described in notes on the side.
 
Kliknite na prepínacie tlačítko na prepnutie medzi vizuálnymi a wikitextovými rozdielmi.
 
The wikitext diff is the same diff tool that is used in the wikitext editors and in the page history.

History

This feature has been available as the first diff tool in the desktop VisualEditor from the 1.31.0-wmf-20 branch onwards (released to Wikimedia production on 6 February 2018). Before that, it was a secondary tool from the 1.29.0-wmf-17 branch onwards (released to Wikimedia production on 21 March 2017).
