DESCRIPTION

10       Algorithm::Dependency::Source::File implements a source where the items
11       are stored in a flat file or a relatively simple format.
12
13   File Format
14       The file should be an ordinary text file, consisting of a series of
15       lines, with each line completely containing the information for a
16       single item.  Blank lines, or lines beginning with the hash character
17       '#' will be ignored as comments.
18
19       For a single item line, only word characters will be used. A 'word
20       character' consists of all letters and numbers, and the underscore '_'
21       character.  Anything that is not a word character will be assumed to be
22       a seperator.
23
24       The first word will be used as the name or id of the item, and any
25       further words in the line will be used as other items that this one
26       depends on. For example, all of the following are legal.
27
28         # A single item with no dependencies
29         Foo
30
31         # Another item that depends on the first one
32         Bar Foo
33
34         # Depending on multiple others
35         Bin Foo Bar
36
37         # We can use different seperators
38         One:Two|Three-Four+Five=Six Seven
39
40         # We can also use multiple non-word characters as seperators
41         This&*&^*&File:  is& & & :::REALLY()Neat
42
43       From the examples above, it should be easy to create your own files.
44

METHODS

46       This documents the methods differing from the ordinary
47       Algorithm::Dependency::Source methods.
48
49   new $filename
50       When constructing a new Algorithm::Dependency::Source::File object, an
51       argument should be provided of the name of the file to use. The
52       constructor will check that the file exists, and is readable, returning
53       "undef" otherwise.
