in reply to Re: Data::Diver polluting $@
in thread Data::Diver polluting $!

Although I mostly agree, I'll try to upload a new release of Data::Diver in short order that adds local($@) any places that it uses eval.

And thanks for mentioning $@ as it saved me from figuring out what was really going on, because I was immediately pretty sure that the problem wasn't with $!, but I didn't immediately realize what the real problem was.

    Here is another, docs lead me to believe these should all work but Dive doesn't

    #!/usr/bin/perl -- use strict; use warnings; use Data::Diver qw/ Dive DiveRef DiveDie /; sub say { print @_, "\n"; } say DiveDie( DiveRef( { qw/ key val / }, \'key' ) ); say DiveDie( Dive( { qw/ key val / }, \'key' ) ); __END__ SCALAR(0x3f90cc) Key not present in hash using SCALAR(0xabe37c) on HASH(0x3f90dc) (from + Data::Diver).

    Problem is in sub Dive, when you're testing if $ref is a hash with eval, you forgot the 1, this line
    -        } elsif(  eval { exists $ref->{$key} }  ) {
    +        } elsif(  eval { exists $ref->{$key}; 1 }  ) {

    I've tested it it works , your test suite doesn't test for this so maybe add to Data-Diver-1.0101/t/base.t the following

    ok( 'val', Dive( { qw/ key val / }, \'key' ) ); ok( 'val', Dive( { qw/ key val / }, 'key' ) ); ok( 'val', DiveVal( { qw/ key val / }, \'key' ) ); ok( 'val', DiveVal( { qw/ key val / }, 'key' ) );

    Also remember the Replacment for Data::Diver due missing license

    For the honor

[Corion]: I like editors that automatically highlight the matching parenthesis (like % in vi), but that's roughly the extent to which I like editor support ;)
[GotToBTru]: same here Corion.
[Corion]: I tried for a short time (well, 8 hours now) to get Perl::Tidy set up but then found that it doesn't support (new-style) signatures and then stopped again ;))
[GotToBTru]: changing the font color of the rest of the document just because I typed a single quote character is annoying
