Global Lua Modules/Error

Error is a global Lua module used for implementing the Error template. It is a copy of Wikipedia's Error module.

Installation[]

Lua installation

Module:

Create Module:Error on your wiki with the following code:

return require('Dev:Error')

Module invocation:

The module can be invoked with the following syntax:

{{#invoke:Error|error|<message>}}
{{#invoke:Error|error|<message>|tag = <tag>}}

Template:

Create Template:Error on your wiki with the following code:

{{#invoke:Error|error|{{{message|{{{1}}}}}}|tag={{{tag|}}}}}

Template usage:

The template can be used with the following syntax:

{{Error|<message>}}
{{Error|<message>|tag = <tag>}}

Usage[]

Invoking the error function renders an HTML element with class "error" containing the error message passed as the first argument.

{{#invoke:Error|error|I am Error}} → I am Error

The output has the same format as the errors produced by parser functions such as #expr or #invoke. Therefore, the parser function #iferror will recognize the output as an error.

{{#iferror: {{#invoke:Error|error|I am Error}}
| Yeah, this is an error.
| Nope, this is something else.
}}

Yeah, this is an error.

By default, the error function wraps the message in strong tags. The named parameter tag can be used to specify another tag. Accepted values are p, div, span and strong, since those are the only values recognized by the #iferror parser function.

{{#invoke:Error|error|I am Error|tag=span}} → I am Error
