Extra QGIS Variables

The Mergin Maps QGIS plugin adds several variables that can be used in QGIS expressions:

Variable name	Sample value	Scope	Description
@mergin_username	martin	global	Name of the user currently logged in to Mergin Maps
@mergin_user_email	martin@example.com	global	Email of the user currently logged in to Mergin Maps
@mergin_url	https://app.merginmaps.com	global	URL of the Mergin Maps service
@mergin_project_name	Tree survey	project	Name of the active Mergin Maps project
@mergin_project_owner	martin	project	Name of the owner of the active project
@mergin_project_full_name	martin/Tree survey	project	Owner and project name joined with a forward slash
@mergin_project_version	42	project	Current version of the active project

A common use case is to use @mergin_username as the default value for one of the fields in a survey layer to automatically track who has added (and/or modified) a particular record.
