|
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.
|
|
|
|
|
|
Status
|
|
------
|
|
|
|
This project is passively maintained. If there is no recent commits it is because:
|
|
|
|
- I did not encountered a bug and nobody reported any.
|
|
- I am happy with the functionalities and nobody asked for new ones.
|
|
- It works on both vim and neovim.
|
|
|
|
If you need anything, please open an issue.

|
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 one the following pattern:
|
|
|
|
* `YYYYMMDDXX ; serial`
|
|
- `YYYY` is the year (4 digits, must start by either `19` or `2`);
|
|
- `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.
|
|
|
|
* `SSSSSSSSSS ; serial`
|
|
- `SSSSSSSSSS` is the UNIX tiemstamp (10 digits, must start by `1`);
|
|
- the word `serial` is not case-sensitive;
|
|
- there can be any number of blanks on each sides of the semicolon.
|
|
|
|
* `XX ; serial`
|
|
- `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.
|
|
|
|
According to those patterns, only dates between 1900 and 2999 will be detected; however this should not be a problem at all. Most importantly, only timestamps between September 9 2001 and March 17 2030 will be detected.
|
|
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
You can set several configuration variables in your vimrc:
|
|
|
|
* `g:dnsserial_auto_update`: Defines whether or not the serial is updated when the zone file is saved (default is 1, set it to 0 to disable).
|
|
* `g:dnsserial_custom_patterns`: List of customs patterns that will be added to the default ones. Order matters, the first matching patters will be used. Customs patterns will be tested before the default ones.
|
|
* `g:dnsserial_patterns`: List of default patterns. It is not advised to change it.
|
|
|
|
|
|
Custom patterns
|
|
---------------
|
|
|
|
A pattern is defined by a dictionary with two keys: `regex` and `matching`.
|
|
|
|
**regex**
|
|
|
|
Contains the regular expression that will be used to search the document for the serial number. All the components of the serial number must be captured with parenthesis.
|
|
|
|
**matching**
|
|
|
|
This is a list of every components of the serial number. Each component is defined by a dictionary. The `type` key must be present and contain one of the allowed types. Depending on the type, several additional keys might be defined. Authorized types and their options are:
|
|
|
|
* `raw`: Raw string.
|
|
* `integer`: An integer that will be incremented.
|
|
- `offset` (int): set the offset by which the integer is incremented. Default is 1.
|
|
- `padding` (int): Force the integer to be 0-padded on the associated number of digits.
|
|
- `date_reset` (bool): If set to 1 and a the serial contains a `date`, the integer will be reseted to 0 if the date is updated. Default is 0.
|
|
* `date`: A formated date that will be updated to the current one.
|
|
- `fmt` (string, mandatory) : the date format according to the `strftime()` specifications. See `:help strftime` for more details.
|
|
|
|
**examples**
|
|
|
|
A simple pattern matching a serial defined as an integer and followed by a comment starting by the word `serial` is:
|
|
|
|
```js
|
|
{
|
|
'regex': '\(\d\+\)\s*;\s*\cserial',
|
|
'matching': [
|
|
{'type': 'integer'}
|
|
]
|
|
}
|
|
```
|
|
|
|
The same example, but having the serial number starting by the current date (YYYYMMDD) and the integer padded on two digits:
|
|
|
|
|
|
```js
|
|
{
|
|
'regex': '\(\d\{8}\)\(\d\+\)\s*;\s*\cserial',
|
|
'matching': [
|
|
{'type': 'date', 'fmt': '%Y%m%d'},
|
|
{'type': 'integer', 'padding': 2, 'date_reset': 1}
|
|
]
|
|
}
|
|
```
