About subst
Definition
- The subst: keyword (short for "substitution") is used as a prefix inside a template code. It changes the way the software expands the template. Ordinarily, a template is expanded "on the fly"; that is, the template code calls a seperate page for the text every time a user views a page it's used on. Placing "subst:" inside the curly brackets tells the software to expand the template immediately upon being saved.
Advantages
- Every a viewer browses a page, the server must get text from a seperate page for every template code used. Although each individual template has little effect, the vast number of template codes used on Wikipedia is causing heavy loading times and a great deal of server load. This problem is solved by subst'ing templates on pages where they don't need to be kept up-to-date or simple. This is particularly true on talk pages.
- Templates are also a prime target for vandalism. Changes made to a single template are instantly propagated to many different pages. In this way, a single edit can vandalise thousands of individual pages. Subst'ing prevents this type of attack, since the template is converted into text and will no longer be updated.
- See Wikipedia:Transclusion costs and benefits for further details.
Usage
- You can subst a template tag by simply adding "subst:" to a template tag. For example, use {{subst:test5}} instead of {{test5}}.

Templates that should NOT be subst'd
- {{main}} - It contributes a certain appearance to part of an article. If the appearance of the template changes again, updates to an article may produce inconsistent appearance for such article links.
- {{tl}} {{tlp}} {{ttl}} {{ti}} {{tic}} {{tls}} {{cl}} - still opposed because they can be lengthy
- Stub templates
- User signature templates - Not be subst'ed without the user's permission. People will just keep adding them as tags instead of subst'ing them.
