Algorithm::Dependency::Source::File - File source for dependency heirachys
DESCRIPTION
Algorithm::Dependency::Source::File implements a source where the items are stored in a flat file or a relatively simple format.
File Format
The file should be an ordinary text file, consisting of a series of lines, with each line completely containing the information for a
single item. Blank lines, or lines beginning with the hash character '#' will be ignored as comments.
For a single item line, only word characters will be used. A 'word character' consists of all letters and numbers, and the underscore '_'
character. Anything that is not a word character will be assumed to be a seperator.
The first word will be used as the name or id of the item, and any further words in the line will be used as other items that this one
depends on. For example, all of the following are legal.
# A single item with no dependencies
Foo
# Another item that depends on the first one
Bar Foo
# Depending on multiple others
Bin Foo Bar
# We can use different seperators
One:Two|Three-Four+Five=Six Seven
# We can also use multiple non-word characters as seperators
This&*&^*&File: is& & & :::REALLY()Neat
From the examples above, it should be easy to create your own files.
METHODS
This documents the methods differing from the ordinary Algorithm::Dependency::Source methods.
new $filename
When constructing a new Algorithm::Dependency::Source::File object, an argument should be provided of the name of the file to use. The
constructor will check that the file exists, and is readable, returning "undef" otherwise.
