The hath package

[Tags: gpl, program]

Hath is a Haskell program for working with network blocks in CIDR notation. When dealing with blocks of network addresses, there are a few things that one usually wants to do with them:

Hath has four modes to perform these functions:

Regexed
This computes a (Perl-compatible) regular expression matching the input CIDR blocks. It's the default mode of operation.
Reduced
This combines small blocks into larger ones where possible, and eliminates redundant blocks. The output should be equivalent to the input, though.
Duped
Shows only the blocks that would be removed by reduce; that is, it shows the ones that would get combined into larger blocks or are simply redundant.
Diffed
Shows what would change if you used reduce. Uses diff-like notation.

Examples:

Combine two /24s into a /23:

$ hath reduced <<< "10.0.0.0/24 10.0.1.0/24"
10.0.0.0/23

Create a perl-compatible regex to be fed to grep:

$ grep -P `hath regexed -i cidrs.txt` mail.log
