NAME

Dancer2::Plugin::Tail - Tail a file from Dancer2

VERSION

Version 0.007

SYNOPSIS

use Dancer2;
use Dancer2::Plugin::Tail;

DESCRIPTION

This plugin will allow you to tail a file from within Dancer2. It's designed to be unobtrusive. So, it is functional just by calling it from your scripts. Edit entries in the Dancer configuration to setup routes and activate files that may be tailed. Additionally, you may define or restrict definition of tailed files.

CONFIGURATION

You may specify the route and access to files. The plugin will only read files so it must have read access to them. The following configuration will generate two routes: '/tail/display' and '/tail/read'.

A sample HTML page with Bootstrap and jQuery is included in the samples directory. Use it as an example to build your own page.

plugins:
  Tail:
    update_interval: 3000
    tmpdir:          '/tmp'
    no_user_defined: 1
    no_defaults:     0
    display:
      method:    'get'
      url:       '/tail/display'
      template:  'tail.tt'
      layout:    'nomenu.tt'
    data:
      method:    'get'
      url:       '/tail/read'
    files:
      id1:    
        heading: 'Server Access Log'
        file:    '/var/logs/access_log'
      id2:    
        heading: 'Server Error Log'
        file:    '/var/logs/error_log'
