Subject: Bug or misundertanding from my part?
Date: Mon, 19 Sep 2005 16:32:35 +0200 [thread overview]
Message-ID: <20050919143235.GA2831@DervishD> (raw)
Hi all :)
In the ZSH manual for 4.2.5 we can read:
{ TRY-LIST } always { ALWAYS-LIST }
First execute TRY-LIST. Regardless of errors, or break, continue,
or return commands encountered within TRY-LIST, execute
ALWAYS-LIST. Execution then continues from the result of the
execution of TRY-LIST; in other words, any error, or break,
continue, or return command is treated in the normal way, as if
ALWAYS-LIST were not present. The two chunks of code are referred
to as the `try block' and the `always block'.
So, this code should print "try list" and "always list", but it
doesn't:
#!/bin/zsh
emulate -L zsh
{
print "try list"
return 13
} always {
print "always list"
return 0
}
print "What?"
The code above just prints "try list" and exits with a return
code of "13", but the manual says that the ALWAYS-LIST is executed
"Regardless of [...] return commands encountered [...]". Am I doing
something wrong? I'm a bit puzzled because the above works if I
change 'return 13' for 'false'.
Thanks a lot in advance :)
