Replace a | in a string with a username. This is just an example to show how complex replacements in TypoScript works. Please don't insert a username on every page like this. It kills caching.

replace.ts

stdWrap.replacement {
	10 {
		search = |
		replace.stdWrap.cObject = COA
		replace.stdWrap.cObject {
			10 = TEXT
			10.data = TSFE:fe_user|user|first_name
			10.noTrimWrap = || |
			20 = TEXT
			20.data = TSFE:fe_user|user|last_name
		}
	}
}
