 | This is a documentation subpage for Template:=. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template may have no transclusions, because it was replaced with a magic word. |
This magic word allows "=" to be used in unnamed template parameters, rather than being interpreted as the separator between the parameter name and value. It evaluates to the equals sign, =. Alternatively, the HTML entity "=" can be used if there is no need for it to be interpreted as wikimarkup, such as when the literal equals-sign is to be displayed to the user. Until June 2022, there was a template at this location with the same function, but it was replaced with a magic word for performance reasons in Phab:T91154.
Do not use syntax like {{Template:=}}, and do not supply a parameter, for example {{=|foo}}. In those cases, the template transcludes as an error message: Error: The retired template {{=}} has been transcluded; see mw:Help:Magic words#Other for details. To fix this, use only the code {{=}} to generate the = character.
Do not use the magic word in URLs rather use percent-encoding or no encoding:
- Wrong:
https://example.com/?arg{{=}}789 - Correct:
https://example.com/?arg%3D789 - Correct:
https://example.com/?arg=789
Usage[edit]
{{Font color|black|yellow|2 + 2 {{=}} 4}}produces: 2 + 2 = 4
You can also use named parameters to bypass the restriction:
{{Font color|black|yellow|3= 2 + 2 = 4}}produces: 2 + 2 = 4
Unlike =, the magic word only delays the interpretation of the symbol as code:
{{concat|<div style{{=}}"font-style:italic">This should be italicised.</div>}}
{{concat|<div style="font-style:italic">This will not be italicised.</div>}}
produces:
This should be italicised.
This will not be italicised.
