=head1 DESCRIPTION |
38
|
|
|
|
|
|
|
|
39
|
|
|
|
|
|
|
This module provides a function that adds specified files to the |
40
|
|
|
|
|
|
|
MacOS Apple Menu "Recent Documents" folder. You can use this module |
41
|
|
|
|
|
|
|
under non-MacOS environments, and it will compile, but it will do |
42
|
|
|
|
|
|
|
nothing. |

|
|

|
|
|
|
|
|
This adds the given items to the Recent Documents folder, for each item |
51
|
|
|
|
|
|
|
that is a pathspec to an existing file. Relative (C<":bar.txt">) as |
52
|
|
|
|
|
|
|
well as absolute filespecs (C<"Lame Drive:stuff:bar.txt">) should work |
53
|
|
|
|
|
|
|
equally well. |
54
|
|
|
|
|
|
|
|
55
|
|
|
|
|
|
|
The number of aliases that this creates in the Recent Documents folder |
56
|
|
|
|
|
|
|
is returned. |
57
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
Under non-MacOS environments, this function does nothing at all, and |
59
|
|
|
|
|
|
|
always returns 0. |
60
|
|
|
|
|
|
|
|
61
|
|
|
|
|
|
|
=item recent_document( file ) |
62
|
|
|
|
|
|
|
|
63
|
|
|
|
|
|
|
This is just an alias to C |
64
|
|
|
|
|
|
|
|
65
|
|
|
|
|
|
|
=item Mac::RecentDocuments::OK() |
66
|
|
|
|
|
|
|
|
67
|
|
|
|
|
|
|
This function returns true iff you are running under MacOS, and if, at |
68
|
|
|
|
|
|
|
compile-time, Mac::RecentDocuments was able to find your Recent |
69
|
|
|
|
|
|
|
Documents folder, and verified that it was a writeable directory. |
70
|
|
|
|
|
|
|
In all other cases, this returns false. |

=head1 IMPORTING, AND :ARGV |
75
|
|
|
|
|
|
|
|
76
|
|
|
|
|
|
|
If you say |
77
|
|
|
|
|
|
|
|
78
|
|
|
|
|
|
|
use Mac::RecentDocuments; |
79
|
|
|
|
|
|
|
|
80
|
|
|
|
|
|
|
then this will by default import the functions C |
81
|
|
|
|
|
|
|
and C. |
82
|
|
|
|
|
|
|
|
83
|
|
|
|
|
|
|
This is equivalent to: |
84
|
|
|
|
|
|
|
|
85
|
|
|
|
|
|
|
use Mac::RecentDocuments qw(:all); |
86
|
|
|
|
|
|
|
|
87
|
|
|
|
|
|
|
If you want to use the module but import no functions, you can say: |
88
|
|
|
|
|
|
|
|
89
|
|
|
|
|
|
|
use Mac::RecentDocuments (); |
90
|
|
|
|
|
|
|
|
91
|
|
|
|
|
|
|
or |
92
|
|
|
|
|
|
|
|
93
|
|
|
|
|
|
|
use Mac::RecentDocuments qw(:none); |
94
|
|
|
|
|
|
|
|
95
|
|
|
|
|
|
|
This module also defines a use-option C<":ARGV"> that causes |
96
|
|
|
|
|
|
|
Mac::RecentDocuments to also call C, at compile |
97
|
|
|
|
|
|
|
time. This should be rather useful with MacPerl droplets. |
98
|
|
|
|
|
|
|
|
99
|
|
|
|
|
|
|
That is, this: |
100
|
|
|
|
|
|
|
|
101
|
|
|
|
|
|
|
use Mac::RecentDocuments qw(:ARGV); |
102
|
|
|
|
|
|
|
|
103
|
|
|
|
|
|
|
is basically equivalent to: |
104
|
|
|
|
|
|
|
|
105
|
|
|
|
|
|
|
BEGIN { |
106
|
|
|
|
|
|
|
use Mac::RecentDocuments; |
107
|
|
|
|
|
|
|
Mac::RecentDocuments(@ARGV); |
108
|
|
|
|
|
|
|
} |
109
|
|
|
|
|
|
|
|
110
|
|
|
|
|
|
|
(The only difference is that if several instances of |
111
|
|
|
|
|
|
|
C |
112
|
|
|
|
|
|
|
C is called only the first time.) |
113
|
|
|
|
|
|
|
|
114
|
|
|
|
|
|
|
When "qw(:ARGV)" is the whole option list, it is interpreted as |
115
|
|
|
|
|
|
|
equivalent to "qw(:ARGV :all)". If you want the C<:ARGV> option |
116
|
|
|
|
|
|
|
without importing anything, explicitly specify the C<":none"> |
117
|
|
|
|
|
|
|
option: |
118
|
|
|
|
|
|
|
|
119
|
|
|
|
|
|
|
use Mac::RecentDocuments qw(:ARGV :none); |
120
|
|
|
|
|
|
|
|

122
|
|
|
|
|
|
|
|
123
|
|
|
|
|
|
|
The module is called Mac::RecentDocuments (no underscore), but |
124
|
|
|
|
|
|
|
the function is called C (with underscore). |
125
|
|
|
|
|
|
|
|
126
|
|
|
|
|
|
|
The module is called Mac::RecentDocuments, not Mac::RecentFiles. |
