vim-dnsserial

Another DNS-zone serial number updater.

Why?

I know this not the first vim plugin available to update a DNS-zone serial number. Here is a few reasons why I chose not to use the canonical one:

• there is no license and therefore it is not free;
• it is unmaintained;
• it is bugged;
• it lacks functionalities.

It chose not to fork the original plugin but to write a new one from scratch mainly for legal purposes, but also because I did not found the code as simple as I expected.

Usage

By default, each time you save a bindzone file, the script will look for the DNS serial number and update it. You can also update it without saving the file by invoking the :DNSSerialUpdate function.

Patterns

In order to be detected, the DNS serial number must match the following pattern:

• YYYYMMDDXX ; serial
  • YYYY is the year (4 digits);
  • MM is the month (2 digits);
  • DD is the day (2 digits);
  • XX is any non-negative number (1 or more digits);
  • the word serial is not case-sensitive;
  • there can be any number of blanks on each sides of the semicolon.

Configuration

You can turn off the automatic serial update by setting let g:dnsserial_auto_update = 0 in your vimrc.
