The original behavior was intentional and fully consistence.
I can understand that you enabled above exception for situations when no
delimiter
is passed and the default space stripping mode is enabled. But when user enables
his own delimiter then for me it's odd that in current xHarbour code it's
hardcoded
that empty token is ignored when only one token exists.
? len( hb_aTokens( "" , "|" ) )
? len( hb_aTokens( "|" , "|" ) )
? len( hb_aTokens( "||" , "|" ) )
do you find above results natural?
Please note that now it's not possible to serialize (convert to text) such array
{ "" }
so later it can be restored from string by hb_aTokens() function.
best regards,
