6 Prima::IniFile - support of Windows-like initialization files
7
9 The module contains a class, that provides mapping of text
10 initialization file to a two-level hash structure. The first level is
11 called sections, which groups the second level hashes, called items.
12 Sections must have unique keys. The items hashes values are arrays of
13 text strings. The methods, operated on these arrays are get_values,
14 set_values, add_values and replace_values.

20 my $ini = create Prima::IniFile FILENAME;
21 my $ini = create Prima::IniFile FILENAME,
22 default => HASHREF_OR_ARRAYREF;
23 my $ini = create Prima::IniFile file => FILENAME,

32 my @vals = $ini-> get_values(SECTION, ITEM);
33 my $nvals = $ini-> nvalues(SECTION, ITEM);

45 $sec->{ITEM} = VALUE;
46 my $val = $sec->{ITEM};
47 delete $sec->{ITEM};
48 my %everything = %$sec;
49 %$sec = ();
50 for ( keys %$sec) { ... }
51 while ( my ($k,$v) = each %$sec) { ... }
52
54 add_values SECTION, ITEM, @LIST
55 Adds LIST of string values to the ITEM in SECTION.
56
57 clean
58 Cleans all internal data in the object, including the name of the
59 file.
60
61 create PROFILE
62 Creates an instance of the class. The PROFILE is treated partly as
63 an array, partly as a hash. If PROFILE consists of a single item,
64 the item is treated as a filename. Otherwise, PROFILE is treated as
65 a hash, where the following keys are allowed:
66
67 file FILENAME
68 Selects name of file.
69
70 default %VALUES
71 Selects the initial values for the file, where VALUES is a two-
72 level hash of sections and items. It is passed to read, where
73 it is merged with the file data.
74
75 get_values SECTION, ITEM
76 Returns array of values for ITEM in SECTION. If called in scalar
77 context, and there is more than one value, the first value in list
78 is returned.
79
80 items SECTION [ HINTS ]
81 Returns items in SECTION. HINTS parameters is used to tell if a
82 multiple-valued item must be returned as several items of the same
83 name; HINTS can be supplied in the following forms:
84
85 items( $section, 1 ) items( $section, all => 1);
86
87 new PROFILE
88 Same as create.
89
90 nvalues SECTION, ITEM
91 Returns number of values in ITEM in SECTION.
92
93 read FILENAME, %PROFILE
94 Flushes the old content and opens new file. FILENAME is a text
95 string, PROFILE is a two-level hash of default values for the new
96 file. PROFILE is merged with the data from file, and the latter
97 keep the precedence. Does not return any success values but, warns
98 if any error is occurred.
99
100 replace_values SECTION, ITEM, @VALUES
101 Removes all values form ITEM in SECTION and assigns it to the new
102 list of VALUES.
103
104 section SECTION
105 Returns a tied hash for SECTION. All its read and write operations
106 are reflected in the caller object, which allows the following
107 syntax:
108
109 my $section = $inifile-> section( 'Sample section');
110 $section-> {Item1} = 'Value1';
111
112 which is identical to
113
114 $inifile-> set_items( 'Sample section', 'Item1', 'Value1');
115
116 sections
117 Returns array of section names.
118
119 set_values SECTION, ITEM, @VALUES
120 Assigns VALUES to ITEM in SECTION. If number of new values are
121 equal or greater than the number of the old, the method is same as
122 replace_values. Otherwise, the values with indices higher than the
123 number of new values are not touched.
124
125 write
126 Rewrites the file with the object content. The object keeps an
127 internal modification flag under name "{changed}"; in case it is
128 "undef", no actual write is performed.
