(tye)Re: Get file make backup

in reply to Re: Get file make backup
in thread Get file make backup

I like this idiom but I recently learned that it doesn't work in at least a few versions of Perl prior to Perl 5.6.0.

So keep that in mind if you plan to use the above.

Which part of "this idiom"? The \4096 part? If that's the case, just leave it out or replace it with undef. -- Randal L. Schwartz, Perl hacker	[reply]

Sorry, I was busy and so unacceptably terse. `do { local *ARGV; @ARGV= $filename; <> }` returns nothing in Perl 5.004 and keeps reading the "current" file in Perl 5.005. I'd be interested in more testing on this as I've just got the two examples at the moment so I'm not sure if the behavior is consistant across all of 5.004 and 5.005. - tye (but my friends call me "Tye")	[reply] [d/l]

So, I've heard. I'm a perl 5.6.0er and a new camel booker so I took the open(FOO, "<", "foo.txt") idoim to heart as it scored a 'righterer' in the veritable tome. open(FOO, "<foo.txt") is more retro! cheers tachyon	[reply]
