Subject: Another interesting (P) effect
Date: Sun, 15 Nov 2015 10:08:14 -0800 [thread overview]
Message-ID: <151115100814.ZM29061@torch.brasslantern.com> (raw)
This isn't new, but given that ${(P)${(f)lines} is an example in the
"Rules" (rule 23), seems worth mentioning:
torch% a=AYY
torch% abc=AYYBEESEE
torch% lines=$'a\nb\nc'
torch% print ${(P)${(f)lines}}
AYY
So (P) parses off the first thing that looks like a parameter name and
discards everything else, with no error.
torch% IFS='' eval 'print ${(P)${(f)lines}}'
AYYBEESEE
