NAME

6       Padre::Util - Padre non-Wx Utility Functions
7

DESCRIPTION

9       The "Padre::Util" package is a internal storage area for miscellaneous
10       functions that aren't really Padre-specific that we want to throw
11       somewhere convenient so they won't clog up task-specific packages.
12
13       All functions are exportable and documented for maintenance purposes,
14       but except for in the Padre core distribution you are discouraged in
15       the strongest possible terms from using these functions, as they may be
16       moved, removed or changed at any time without notice.

FUNCTIONS

19   "slurp"
20           my $content = Padre::Util::slurp( $file );
21           if ( $content ) {
22               print $$content;
23           } else {
24               # Handle errors appropriately
25           }
26
27       This is a simple slurp implementation, provided as a convenience for
28       internal Padre use when loading trivial unimportant files for which we
29       don't need anything more robust.
30
31       All file reading is done with "binmode" enabled, and data is returned
32       by reference to avoid needless copying.
33
34       Returns the content of the file as a SCALAR reference if the file
35       exists and can be read.
36
37       Returns false if loading of the file failed.
38
39       This function is only expected to be used in situations where the file
40       should almost always exist, and thus the reason why reading the file
41       failed isn't really important.
42
43   "newline_type"
44           my $type = Padre::Util::newline_type( $string );
45
46       Returns "None" if there was not "CR" or "LF" in the file.
47
48       Returns "UNIX", "Mac" or "Windows" if only the appropriate newlines
49       were found.
50
51       Returns "Mixed" if line endings are mixed.
52
53   "parse_variable"
54           my $version = Padre::Util::parse_variable($file, 'VERSION');
55
56       Parse a $file and return what $VERSION (or some other variable) is set
57       to by the first assignment.
58
59       It will return the string "undef" if it can't figure out what $VERSION
60       is. $VERSION should be for all to see, so "our $VERSION" or plain
61       $VERSION are okay, but "my $VERSION" is not.
62
63       "parse_variable()" will try to "use version" before checking for
64       $VERSION so the following will work.
65
66           $VERSION = qv(1.2.3);
67
68       Originally based on "parse_version" from ExtUtils::MakeMaker.
69
70   "get_matches"
71       Parameters:
72
73       ·   The text in which we need to search
74
75       ·   The regular expression
76
77       ·   The offset within the text where we the last match started so the
78           next forward match must start after this.
79
80       ·   The offset within the text where we the last match ended so the
81           next backward match must end before this.
82
83       ·   backward bit (1 = search backward, 0 = search forward) - Optional.
84           Defaults to 0.
85
86   "_T"
87       The "_T" function is used for strings that you do not want to translate
88       immediately, but you will be translating later (multiple times).
89
90       The only reason this function needs to exist at all is so that the
91       translation tools can identify the string it refers to as something
92       that needs to be translated.
93
94       Functionally, this function is just a direct pass-through with no
95       effect.
96
97   "share"
98       If called without a parameter returns the share directory of Padre.  If
99       called with a parameter (e.g. "Perl6") returns the share directory of
100       Padre::Plugin::Perl6. Uses File::ShareDir inside.
