# Pidlock

[![Build Status](https://travis-ci.org/abangratz/pidlock.png?branch=master)](https://travis-ci.org/abangratz/pidlock)

This is a ruby library for using pid-file based locking of programs/daemons to prevent multiple parallel running tasks.

## Prerequisites

The gem ``sys/proctable`` is required.

## Usage

```ruby
require 'sys/proctable'

pidlock = Pidlock.new('my.pid')   # Instantiates a lock
pidlock.lock                      # tries to create a lock file '/var/run/my.pid';
                                  # raises an error if the file is locked or a program exists that
                                  # has the same basename and pid (here: 'my')
...
pidlock.unlock                    # closes and removes the file
```

## TODO

* test unlocking in projects.
