[Parseperl-discuss] Moving an Expression

[Stuart J. <sa...@th...>]

I have a line of code like:

foo(bar("Hello World"));

And I want to re-factor it into:

bar("Hello World");

Of course the real statements are likely to be more complex, multiple 
lines, conditionals, etc.  I can remove the 'foo' bareword easily enough 
but I can't figure out how to get rid of the outer list without loosing 
the inner 'bar' expression.

Is PPI currently capable of such things?

I have been trying variations on the code below.

thanks,
Stuart Johnston


my $code = q{foo(bar("Hello World"));};
my $d = PPI::Document->new(\$code);
my $foo = $d->find_first('PPI::Token::Word');
my $list = $foo->next_sibling;
my $exp = $list->child(0);
$exp->remove;
$list->delete;
$foo->insert_after($exp);
