gawk: unexpected behavior, but not a bug

[Thomas Schwinge]

Hello!

They told me it's not a gawk (GNU Awk 3.1.5) bug, but I thought I'd
nevertheless report it here.

Given the attached `ThomasSchwinge.txt' it took me roughly one hour and
finally the help of three people in the freenode #awk irc channel to
figure out what was going on here:

#v+
$ awk < data/Main/ThomasSchwinge.txt 'BEGIN { FS = ": "; name = "unknown"; 
email = "address@hidden" } $1 ~ /\* Name$/ { name = $2 } $1 ~ /\* Email$/ { 
email = $2 } END { print name " <" email ">" }'
><address@hidden
#v-

I had expected to get ``Thomas Schwinge <address@hidden>'' as output.


In the end `igli' and `redondos' had an idea:

#v+
$ awk < data/Main/ThomasSchwinge.txt 'BEGIN { FS = ": "; name = "unknown"; 
email = "address@hidden" } { sub("\r$", "") } $1 ~ /\* Name$/ { name = $2 } $1 
~ /\* Email$/ { email = $2 } END { print name " <" email ">" }'
Thomas Schwinge <address@hidden>
#v-

Who would have thought about that...  Not me, for sure.


Regards,
 Thomas
