A Template is a special type of page designed to be transcluded within other pages. Templates allow editors to automatically insert frequently-used images, code, and formatting on a page. We use templates extensively on BG3Wiki, as they allow the use of easily accessible and consistent design, layout and formatting.
Template creation
Template creation is an essential part of the technical BG3Wiki workflow. However, it's important to take care when creating or improving templates.
To create or edit templates you need access to them. This can be requested on the Discord or by visiting an admin's talk page.
What to keep in mind
Ideally, new templates should be:
- Easy to use, with as few parameters as possible.
- Have clear and easy to understand template documentation with examples.
- Have easy to use TemplateData.
Important considerations
Some important considerations when creating templates:
- Line breaks interact unexpectedly with the table parser, which can break some templates.
- Adding a pipe to a template parameter {{{parameter}}} > {{{parameter|}}} will provide it with a default value (in this case, an empty string).
- This is important to remember when using the {{#if:}} parser function, since in cases where a parameter is undefined, {{{parameter}}} will return the value "true", whereas {{{parameter|}}} will return the value "false".
- It is also important to remember when a parameter is used as a value, since in cases where a parameter is undefined, {{{parameter}}} will return the value "{{{parameter}}}", whereas {{{parameter|}}} will return its default value (in this case, an empty space).
- Expr and ifeq, when evaluating numbers, produce different results. This is because expr treats numbers as floats, whereas ifeq treats them as integers.
Template documentation
Template creators are encouraged to document (on the template's page itself as well as via the TemplateData button on the same page) how to use that template, including usage examples and accepted values for any template parameters. If you're unfamiliar with a particular template, navigate to its page to learn how it works. If a template page does not show any usage instructions, it could still be a work in progress, and you may want to check with its creator before using it.
See All Pages (Template namespace) for a full list of available templates on bg3.wiki.
Cargo database
Templates also allow the wiki to populate database tables with stored values using [Cargo queries. This allows the wiki to create automatically generated lists of items or spells.
