apachelogregex.cr

ApacheLogRegex.cr is a crystal lang port of weppos's apachelogregex gem. It provides functionalities to parse a line from an Apache log file into a hash.

Installation

Add this to your application's shard.yml:

dependencies:
  apachelogregex.cr:
    github: a3104/apachelogregex.cr

Usage

require "apachelogregex"

The following one is the most simple example usage. It tries to parse the access.log file and echoes each parsed line.

format = %{%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"}
parser = ApacheLogRegex.new(format)

File.each_line("/var/apache/access.log") do |line|
  parser.parse(line)
  # {"%r"=>"GET /blog/index.xml HTTP/1.1", "%h"=>"87.18.183.252", ... }
end

More often, you might want to collect parsed lines and use them later in your program. The following example iterates all log lines, parses them and returns an array of Hash with the results.

format = '%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"'
parser = ApacheLogRegex.new(format)

File.readlines('/var/apache/access.log').collect do |line|
  parser.parse(line)
  # {"%r"=>"GET /blog/index.xml HTTP/1.1", "%h"=>"87.18.183.252", ... }
end
