Template talk:Lifespan

Logic

Version 1

Check brackets; if default (parentheses around full output) display opening bracket
If the birth or death parameter is missing or empty, display error message, categorize the page, and proceed to closing bracket check
Else (birth+death exist and not empty), if error checking (parameter err) is on, display any non-date parameter error messages and maintenance notices; continue
Display optional content label ("lifespan: "). If parameter 'Prefix' exists suppress label; display error message if error-checking is on; continue
Display optional birth prefix
Display optional circa for birth (or for both birth & death)
Display birth year or, if requirements/constraints are ignored display error message(s) and categorize the page; continue
Display optional alternative birth year or, if requirements/constraints are ignored display error message(s) and categorize the page; continue
Display optional 1st suffix to indicate era straddle (BC-AD or BCE-CE)
Display date span separator per MOS:YEAR and MOS:YEARRANGE
If prefixes are used, display the death prefix
Display optional circa for death (or both birth & death)
Display death year or, if requirements/constraints are ignored display error message(s) and categorize the page; continue
Display optional alternative death year or, if requirements/constraints are ignored display error message(s) and categorize the page; continue
Display optional date-span suffix (implied default is AD/CE, BC-AD and BCE-CE notations are functionally identical) or the 2nd suffix of era straddle
Error-check date parameters relative to their suffix; display any error messages; continue
If age range is processed:
1. Check brackets: if around age only, disregard full-output bracket, add space and open age bracket; else add comma & space
2. Check age label (default is "aged")
3. If it exists, pass circa to the age range
4. If there are alternative years, calculate & display age range(s) relative to birth/death configuration, and the suffix; else only consider the suffix to calculate & display range, after checking whether birth and death occurred in the same year
5. Add trailing static text "years"
If age in years is processed instead:
1. Check brackets as in age range above
2. Check age label
3. If it exists, pass circa to the age
4. Check whether birth and death occurred in the same year and display static text if so; else calculate & display the age considering the birthday (relative to death date), and the suffix
5. Add trailing static text "years"
End else (birth+death exist and not empty)
If brackets are not removed, display closing bracket and exit, else exit
