how to trap errors?

redss has asked for the wisdom of the Perl Monks concerning the following question:

I have a program that calls a method from a package, which sometimes makes the program die (all logic & syntax is correct)

How can I make perl trap the error, so that it will continue instead of dying?

eval BLOCK is what you want, `my $foo = eval { $obj->method(@args) }; warn "Oops! ", $@ if $@;` [download] After Compline, Zaxo	[reply] [d/l]

See the documentation for eval. `eval { ## code that may throw errors }; if( $@ ) { ## Handle errors }` [download]	[reply] [d/l]

eval block do a good work for what you wants, but I recomend you to look of Exception classes or Error class at CPAN site. IMO theses classes implements good practices of exception management. Solli Moreira Honorio Sao Paulo - Brazil	[reply]
