{{subst:
 | This template should always be substituted (i.e., use {{subst:Delay subst}}). |
Usage edit
With certain coding, subst: does not automatically convert when it is saved. An editor can create wikitext that is only converted when saved again.
Normally wikitext like {{subst:a}} is not saved as {{subst:a}} if {{template:a}} exists, because subst: saves the coding of template:a in its place.
This template makes it easy to save preload pages such as Template:RMassist/preload.
Delaying template substitution edit
"Subst" can be delayed with one save by creating and using {{delay subst}}.
| template used | template coding | Paste or type | Save | Result |
|---|---|---|---|---|
| Template:Delay subst | {{subst:
|
{{subst:delay subst}}a|b}}
|
save page | {{subst:a|b}}
|
On the next save (with or without edits elsewhere on the page) results in substitution of template "a".
