Diff

This template is intended to be useful for creating links to "diffs"; that is, links to pages that show the differences between two versions of a wiki page.

Every version of a page has a revision ID, which you can find from the history of the page by looking at the timestamp link for the edit. The timestamp link is in this form:
http[s]://en.wikipedia.org/w/index.php?title=SomePageName&oldid=442212827
The number after oldid= is the revision ID.

Given one or two revision IDs, you can construct links to several types of diffs.

Usage

{{Diff

|title |diff |oldid |label

|diffonly=yes}}

• titleCèṭa'an:SndsThe title of the page (optional in most cases)
• diffCèṭa'an:SndsThe ID or keyword that is used against the base ID. Possible keywords are:

  curCèṭa'an:SndsCompare with the current version of a page.

  prevCèṭa'an:SndsCompare with the previous version of a page.

  nextCèṭa'an:SndsCompare with the next version of a page.

  idCèṭa'an:SndsThis should be larger than oldid.

• oldidCèṭa'an:SndsThe base ID onto which the diff is generated.
• labelCèṭa'an:SndsText to display as link (optional)Cèṭa'an:Nsmdnsno label will generate a numbered link as the label.
• |diffonly=yesCèṭa'an:SndsDisplays the page comparisons only (optional)Cèṭa'an:Nsmdnsparameter name required if used.

Only the diff parameter is required; all other parameters are optional. Omitted parameters must be empty (by using a double pipe). You can also use the named parameters title, diff, oldid, and label.

Helper subtemplate

In order to make this template simpler to use the helper subtemplate {{Diff/translator}} is available, to be used only in the preview window.

Syntax

{{Diff/translator

|label

|url=diff URL}}

For instance, imagine you want to refer to the following diff URL: https://en.wikipedia.org/w/index.php?title=Main_Page&diff=139993&oldid=139992&diffonly=1; you only need to transcribe that URL in the {{Diff/translator}} subtemplate and produce a preview, without saving the page:

{{Diff/translator

|Sic exorsi sumus

|url=https://en.wikipedia.org/w/index.php?title=Main_Page&diff=139993&oldid=139992&diffonly=1}}

↳ Cèṭa'an:Diff/translator

Now copy the code generated (Cèṭa'an:Diff/translator) into the edit window where {{Diff/translator}} was and publish the page.

Examples

Below each example in the left-hand column is the pseudocode for that example in brown italics and indented. Elements that should be entered literally are in Cèṭa'an:Uu. When a parameter is left blank, the resulting two adjacent pipes are underlined (but not bolded): ||.

Code	Output
{{Cèṭa'an:Uu|Main Page|prev|204901573|Diff between a numbered version and the previous version}} {{Cèṭa'an:Uu|page|prev|oldid|label}}	Diff between a numbered version and the previous version This is the form that would be used most often. The diff= parameter (parameter number 2) should be the word prev. The oldid= parameter (parameter number 3) should be the known revision number.
{{Cèṭa'an:Uu|Foobar|616706711|616706707|Diff between two numbered versions of a page}} {{Cèṭa'an:Uu|page title|diff|oldid|label}}	Diff between two numbered versions of a page The title= parameter (parameter number 1) should be a name of a page, for instance Foobar. The diff= parameter (parameter number 2) should be the larger revision number. The oldid= parameter (parameter number 3) should be the smaller revision number.
{{Cèṭa'an:Uu||616706711|616706707|Diff between two numbered versions of a page without title parameter}} {{Cèṭa'an:Uu||diff|oldid|label}}	Diff between two numbered versions of a page without title parameter The title= parameter (parameter number 1) may be left blank, thereby leaving a double pipe. The diff= parameter (parameter number 2) should be the larger revision number. The oldid= parameter (parameter number 3) should be the smaller revision number.
{{Cèṭa'an:Uu|Wikipedia:Pagediff|204934693|204901573|Diff between two numbered versions of a page in Wikipedia namespace}} {{Cèṭa'an:Uu|page|diff|oldid|label}}	Diff between two numbered versions of a page in Wikipedia namespace The title= parameter (parameter number 1) should be a name of a page, for instance Wikipedia:Pagediff. The diff= parameter (parameter number 2) should be the page revision to appear on the right (proposed change). The oldid= parameter (parameter number 3) should be the page revision to appear on the left (original).
{{Cèṭa'an:Uu|Main Page|next|204901573|Diff between a numbered version and the subsequent version}} {{Cèṭa'an:Uu|page|next|oldid|label}}	Diff between a numbered version and the subsequent version The diff= parameter (parameter number 2) should be the word next. The oldid= parameter (parameter number 3) should be the known revision number.
{{Cèṭa'an:Uu|Main Page|cur|204901573|Diff between a numbered version and the current version of a page}} {{Cèṭa'an:Uu|page|cur|oldid|label}}	Diff between a numbered version and the current version of a page The diff= parameter (parameter number 2) should be the word cur. The oldid= parameter (parameter number 3) should be the known revision number.
{{Cèṭa'an:Uu|Main Page|cur||Diff showing the most recent change to a page}} {{Cèṭa'an:Uu|page|cur||label}}	Diff showing the most recent change to a page The diff= parameter (parameter number 2) should be the word cur. The oldid= parameter (parameter number 3) should be empty.
{{Cèṭa'an:Uu|Main Page||204901573|A link to a numbered version of a page}} {{Cèṭa'an:Uu|pageCèṭa'an:Uuoldid|label}}	A link to a numbered version of a page The diff= parameter (parameter number 2) should be empty. The oldid= parameter (parameter number 3) should be the known revision number. The result is not actually a diff, so this might be considered misuse of the template. See the {{oldid}} template.
{{Cèṭa'an:Uu|Main Page|204901573|202506579|Comparison display without page display of two numbered versions of a page |diffonly=yes}} {{Cèṭa'an:Uu|page|diff|oldid|label|diffonly=yes}}	Comparison display without page display of two numbered versions of a page The title= parameter (parameter number 1) should be a name of a page, for instance Main Page. The diff= parameter (parameter number 2) should be the larger revision number. The oldid= parameter (parameter number 3) should be the smaller revision number. The diffonly= parameter, which must include the parameter name, can only be set to yes
