=head1 DESCRIPTION |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
With the PROXYSUBS option to WriteConstants, this module generates |
27
|
|
|
|
|
|
|
better XS code, with 4 optional variants. |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
Each symbol is added as CONSTSUB at BOOT time, as via C
|
30
|
|
|
|
|
|
|
{value}>. Undefined names I<(#undef NAME)> will be stored in a |
31
|
|
|
|
|
|
|
special C namespace, because |
32
|
|
|
|
|
|
|
accessing an undefined name should throw a different error "Your |
33
|
|
|
|
|
|
|
vendor has not defined MyPackage macro NAME", and not "Undefined |
34
|
|
|
|
|
|
|
subroutine &MyPackage::NAME". |
35
|
|
|
|
|
|
|
|
36
|
|
|
|
|
|
|
There's no run-time lookup for matching names in the constant |
37
|
|
|
|
|
|
|
function, but there's still AUTOLOAD needed to catch unknown names and |
38
|
|
|
|
|
|
|
a short dispatch for matching types. |

NOTICE: |
41
|
|
|
|
|
|
|
|
42
|
|
|
|
|
|
|
ExtUtils::Constant::ProxySubs versions older than 0.23_04 creates |
43
|
|
|
|
|
|
|
code usable only >= 5.14. There is no official CPAN version which |
44
|
|
|
|
|
|
|
creates usable code yet. The CPAN maintainers think p5p should sort it |
45
|
|
|
|
|
|
|
out, which they didn't for the last 7 years. |

=head1 OPTIONS |
48
|
|
|
|
|
|
|
|
49
|
|
|
|
|
|
|
PROXYSUBS can be used with an optional hashref of 4 exclusive options. |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
'autoload', 'croak_on_error' and 'croak_on_read' can not be used together. |
52
|
|
|
|
|
|
|
'push' and 'croak_on_read' cannot be used together. |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
=over 4 |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
=item autoload |
57
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
This option generates an XS AUTOLOAD function which dispatches to the |
59
|
|
|
|
|
|
|
XS C function. Only auto-generated C and XS code is needed, no manual |
60
|
|
|
|
|
|
|
addition of C as generated by L. |
61
|
|
|
|
|
|
|
|

|

|
|
|
B |
63
|
|
|
|
|
|
|
With 5.6 the error message for undefined macros is not |
64
|
|
|
|
|
|
|
"Your vendor has not defined MyPackage macro NAME", but |
65
|
|
|
|
|
|
|
"Undefined subroutine &MyPackage::NAME" |
66
|
|
|
|
|
|
|
|
67
|
|
|
|
|
|
|
=item push |
68
|
|
|
|
|
|
|
|
69
|
|
|
|
|
|
|
This option keeps a list of all added constants. |
70
|
|
|
|
|
|
|
|
71
|
|
|
|
|
|
|
E.g. |
72
|
|
|
|
|
|
|
NAME => 'MyPackage', |
73
|
|
|
|
|
|
|
PROXYSUBS => { push => 'CONSTNAMES' }, |
74
|
|
|
|
|
|
|
will create C<@MyPackage::CONSTNAMES>. |
75
|
|
|
|
|
|
|
|
76
|
|
|
|
|
|
|
=item croak_on_error |
77
|
|
|
|
|
|
|
|
78
|
|
|
|
|
|
|
Errors in run-time name lookup via XS constant is normally handled by |
79
|
|
|
|
|
|
|
AUTOLOAD. With croak_on_error the AUTOLOAD function can be |
80
|
|
|
|
|
|
|
simplified, errors with missing undefined names are thrown directly in |
81
|
|
|
|
|
|
|
the XS Cfunction. |
82
|
|
|
|
|
|
|
|
83
|
|
|
|
|
|
|
The XS caller context might be different to the pure-perl AUTOLOAD |
84
|
|
|
|
|
|
|
context though, identifying the source location of the error. |
85
|
|
|
|
|
|
|
|
86
|
|
|
|
|
|
|
=item croak_on_read |
87
|
|
|
|
|
|
|
|
88
|
|
|
|
|
|
|
Similar to croak_on_error, but much more restrictive. For each |
89
|
|
|
|
|
|
|
variable which should report the "Your vendor has not defined |
90
|
|
|
|
|
|
|
MyPackage macro NAME" error, a magic getter and setter hook is added |
91
|
|
|
|
|
|
|
to throw this error. |
92
|
|
|
|
|
|
|
|
93
|
|
|
|
|
|
|
This option creates code usable only since Perl 5.24, so don't |
94
|
|
|
|
|
|
|
use it with any CPAN module! |
