Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted

This meta template returns a state of error (recognized as such by a wiki parser function), and optionally an error-message text in red (visible for the user). It is used by other templates to signal an error, for example invalid input, which can then either be displayed to the editor or caught and handled by other templates.

Usage

  • Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted → Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted
  • Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted → Lua error: Cannot create process: proc_open(/dev/null): Failed to open stream: Operation not permitted
  • Compare, used in a Parser Function: {{#expr:Foo}} → Expression error: Unrecognized word "foo".
  • {{#iferror:{{error|Foo}} | {{y}} | {{n}} }} → Green tickY

Tag option

The tag to contain the error message can be given through the tag parameter, but it will only accept span, div, p, and strong, since those are the only tags recognized by the {{#iferror}} parser function. It defaults to strong, the tag generated e.g. by {{#expr}}. To prevent strong message, use one of the other tags, e.g. tag=span.
