Sort::Versions allows easy sorting of mixed non-numeric
|
|
and numeric strings, like the "version numbers" that many
|
|
shared library systems and revision control packages use.
|
|
This is quite useful if you are trying to deal with shared
|
|
libraries. It can also be applied to applications that
|
|
intersperse variable-width numeric fields within text.
|
|
Other applications can undoubtedly be found.
|
|
|
|
For an explanation of the algorithm, it's simplest to look
|
|
at these examples:
|
|
|
|
1.1 < 1.2
|
|
1.1a < 1.2
|
|
1.1 < 1.1.1
|
|
1.1 < 1.1a
|
|
1.1.a < 1.1a
|
|
1 < a
|
|
a < b
|
|
1 < 2
|
|
1 < 0002
|
|
1.5 < 1.06
