Expansion depth test (purge)
edt 0
Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.
Template | Code | Comment |
---|---|---|
1x | {{{1}}}
|
Expand parameter one. A variable template. |
Tc | in
|
Constant template always returns "in". |
Xpdt/3 |
|
Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.

Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.
Template | Code | Comment |
---|---|---|
1x | {{{1}}}
|
Expand parameter one. A variable template. |
Tc | in
|
Constant template always returns "in". |
Xpdt/3 |
|
Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

{{Help:Expansion depth/demo}}
edt 6
Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.
Template | Code | Comment |
---|---|---|
1x | {{{1}}}
|
Expand parameter one. A variable template. |
Tc | in
|
Constant template always returns "in". |
Xpdt/3 |
|
Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

edt 7
Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.
Template | Code | Comment |
---|---|---|
1x | {{{1}}}
|
Expand parameter one. A variable template. |
Tc | in
|
Constant template always returns "in". |
Xpdt/3 |
|
Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.

Expansion adds three levels of nesting plus any levels in the parameter, before it subtracts three levels plus any levels in the parameter. Its numbers are output in blue and marked by #if: for the parser function part and 1x: for the template. |
In the output every number in the sequence except zero represents a change in nesting level. Each section is reduced to level zero.

Forty levels of nesting are expanded in MediaWiki software. The forty-first level exceeds the expansion depth level and causes an error in its place.
Three templates are used in the demonstration. This template also includes itself to produce the second half of the page.
