A diff (short for difference) displays the changes between two revisions of a page. Diffs are a fundamental component of navigation and content moderation on MediaWiki wikis.
The platforms in the wiki ecosystem have several versions of a diff depending on which device and installation of MediaWiki is being used.
When and why to use a diff?
The main reason to use a diff is to review a specific change to a page made by yourself or someone else. There are many possible reasons to do this:
- To help find instances of vandalism
- To determine when a section, sentence, or word was added or removed
- To determine which editor made a given change
- As a starting point to further actions as the diff contains မႄးထတ်း, ၶိုၼ်ၶိုၼ်း, and other actions as well as links to the editor's user and talk pages.
How to navigate to view a diff?
The most common way to view a diff is through the "Revision history". This is accessible via the "တူၺ်းပိုၼ်း" tab. From there, you can use "ဢွၼ်တၢင်း" to view diffs of single revisions, or use the radio buttons and the "ၼိူင်းၵၼ်တူၺ်း ၶေႃႈၶူၼ်ႉၶႆႈ ၸိူဝ်းလိူၵ်ႈဝႆႉ" button to view diffs across multiple revisions.
Most special pages that list changes will usually include links to diffs, such as:
Another way to view a diff is with the Special:Diff page.
To use this, you must know the IDs of the revisions you want to compare.
Revision IDs can be retrieved by looking at the diff=123
portion of a diff URL, where 123
is the diff ID.
Additionally, you can use the value of the oldid
parameter to get the diff of that revision against the previous one.
Components to a diff
Below is a visual representation of the important components of a diff page which you will see when viewing the difference between two versions.
This interactive example shows the top of the diff page (some of the links are dummy links).
The older revision is shown on the left, the newer revision on the right.

Unchanged Text
Unchanged text is dark grey on light grey (only parts before and after changed text are shown).
Previous diff | Newer diff | ||
---|---|---|---|
|
Moved text
Identical text that has moved from one place to another is usually represented as added and removed text. On MediaWiki installations using Wikidiff2 , there may be an arrow icon more clearly indicating where the moved text went to.
Added text
Lines containing added text have a plus icon (+) before them. The added words and characters are highlighted and in bold.
Removed text
Lines containing removed text have a minus icon (−) before them. The removed words and characters are highlighted and in bold.
Replaced text
We can see what has been replaced with new content when there's a + icon and a − icon next to the phrase where the change happened.
Paragraphs which have changed are black on white, with an orange border on the old revision side and a blue border on the new version side.
Inserted and removed text is highlighted with the border color and in bold. Where whole paragraphs have been removed or inserted, no highlighting or bolding is applied and the other side is blank.

Linking to a diff
Diffs can be linked to by copying the URL while viewing the diff — this URL has two parameters, diff
and oldid
.
Linking to a diff from outside a wiki can be done by using the full URL, for example:
https://mediawiki.org/w/index.php?diff=1242287
The diff special page at Special:Diff makes it easier to create shorter URLs which redirect to diffs.
From within a wiki, these links can take the following forms:
[[Special:Diff/1242287]]
→ Special:Diff/1242287 – Shows the diff to the previous revision of the same page.[[Special:Diff/1242287/prev]]
→ Special:Diff/1242287/prev – Shows the diff to the previous revision of the same page.[[Special:Diff/1242287/next]]
→ Special:Diff/1242287/next – Shows the diff to the next revision of the same page.[[Special:Diff/1242287/cur]]
→ Special:Diff/1242287/cur – Shows the diff to the current revision of the same page.[[Special:Diff/1242286/1242287]]
→ Special:Diff/1242286/1242287 – Shows the diff between the specified revisions of the same page which may also be reversed, e.g.[[Special:Diff/1242287/1242286]]
→ Special:Diff/1242287/1242286, though one should avoid this.
These links may be used in the edit summary as well as being adapted like any other internal links, e.g. [[Special:Diff/1242286/1242287|see this diff]]
→ see this diff.
For example, the full URL [https://mediawiki.org/w/index.php?diff=1242287 1242287]
could also be written as [[Special:Diff/1242287|1242287]]
.
By default, the later revision of the page is displayed in full below the diff — this can be turned off via a preference ("ယႃႇပေၼႄ လွင်ႈၶဝ်ႈပႃးၼႂ်း ၼႃႈလိၵ်ႈ ၸွမ်းၼင်ႇ လွၵ်းၽၢႆႇတႂ်ႈၼႆႉ") or by setting diffonly=1
in the URL.
Links to diffs without the page text can be created:
{{canonicalurl:Special:Diff/1242287|diffonly=1}}
→ https://www.mediawiki.org/w/index.php?title=Special:Diff/1242287&diffonly=1
Inline diffs
MediaWiki version: | ≥ 1.35 |
Since MediaWiki 1.35, an inline diff (also known as a unified diff) is available.
As of 2022 this is only available with the wikidiff2 engine.
Inline diffs can be accessed by passing the diff-type=inline
parameter in the URL (example).
MediaWiki version: | ≥ 1.41 |

User Preferences
The following user preferences are available in the "ၼိူင်း" section of the "ၽၢင်ႁၢင်ႈ" preferences tab:
- ယႃႇပေၼႄ လွင်ႈၶဝ်ႈပႃးၼႂ်း ၼႃႈလိၵ်ႈ ၸွမ်းၼင်ႇ လွၵ်းၽၢႆႇတႂ်ႈၼႆႉ
- Toggle the display of the page text below the diff. This text is the later of the two revisions of the page.
- ဝၢႆးသေႁဵတ်း ႁူၼ်လင်ၶိုၼ်းယဝ်ႉၼႆ ယႃႇပေၼႄ လွင်ႈၼိူင်းၵၼ် ၼၼ်ႉလႃႈ
- Whether to show the diff of the rolled back revision after a rollback.
Some extensions also add their own preferences related to diffs. One such extension is Extension:RevisionSlider , which can be disabled in preferences using the "ယႃႇပေၼႄ ပႅၵ်ႈထေႃ လွင်ႈၶူၼ်ႉၶႆႈ" preference in that section.
