17 This module provides a simple, correct way to increment a Perl module
18 version number. It does not attempt to guess what the original version
19 number author intended, it simply increments in the smallest possible
20 fashion. Decimals are incremented like an odometer. Dotted decimals
21 are incremented piecewise and presented in a standardized way.
22
23 If more complex version manipulation is necessary, you may wish to
24 consider Perl::Version.
25
27 This module uses Sub::Exporter for optional exporting. Nothing is
28 exported by default.

30 "next_version"
31 my $new_version = next_version( $old_version );
32
33 Given a string, this function make the smallest logical increment and
34 returns it. The input string must be a "lax" version numbers as
35 defined by the version module. The string "undef" is treated as 0 and
36 incremented to 1. Leading or trailing periods have a 0 (or "v0")
37 prepended or appended as appropriate. For legacy reasons, given no
38 argument or a literal "undef" (not the string "undef"), the function
39 returns 0.
40
41 Decimal versions are incremented like an odometer, preserving the
42 original number of decimal places. If an underscore is present
43 (indicating an "alpha" version), its relative position is preserved.
44 Examples:
45
46 0.001 -> 0.002
47 0.999 -> 1.000
48 0.1229 -> 0.1230
49 0.12_34 -> 0.12_35
50 0.12_99 -> 0.13_00
51
52 Dotted-decimal versions have the least significant element incremented
53 by one. If the result exceeds 999, the element resets to 0 and the
54 next most significant element is incremented, and so on. Any leading
55 zero padding is removed. Examples:
56
57 v1.2.3 -> v1.2.4
58 v1.2.999 -> v1.3.0
59 v1.999.999 -> v2.0.0
60
61 NOTE: Due to changes in the interpretation of dotted-decimal version
62 numbers with alpha elements in version 0.9913 and later, the notion of
63 the 'next' dotted-decimal alpha is ill-defined. Version::Next no
64 longer supports dotted-decimals with alpha elements and a fatal
65 exception will be thrown if one is provided to "next_version".
