{user:field}

Returns information about the currently logged-in user. With no parameter it returns the login username (a quick lookup that does not touch the database). The keyword password returns the plain-text password, but only when the request used HTTP Basic auth. The keywords role and permission both return the user permission role for the current slice: super, administrator, editor, author, or undefined. The keyword id returns the long item id of the user Reader record. Any other value is read as a field id (or a _#ALIAS) from the logged-in user Reader item, so user headline........ returns that field, typically the display name. Because the result depends on who is logged in, any view that uses this command is never cached, and on a public page with nobody logged in the user-specific values are empty. Note: a bare username read returns nothing in an anonymous context; prefer a field read such as user headline........ for display. For a cacheable variant that reads the same Reader item see xuser; to look up another user by id see userinfo.
