Subject: About zsh-users 8489 (exception handling)
Date: Wed, 28 Sep 2005 01:47:26 +0200 [thread overview]
Message-ID: <20050927234726.GC988@DervishD> (raw)
Hi all :)
In zsh-users 8489 Bart Schaeffer proposes using this syntax:
{ ${:?THROW} } 2>/dev/null
instead of this one:
{ ${*ERROR*} } 2>/dev/null
for generating the exception in "throw" function, since the
latter may become valid syntax in the future.
Unfortunately, that doesn't work because ${:?...} *exits* from
the shell, so the valid syntax would be:
( ${:?THROW} ) 2>/dev/null
For me, using a subshell just to generate the exception seems a
bit excessive. Is there any other way of generating an error (the
exception) without using a subshell and without using current invalid
syntax that could become valid in the future?
Thanks a lot :)
