Memcached StartupItem for Mac OS X

s0nspark (Tim Ferrell) — Sun, 17 Sep 2006 22:15:16 GMT

Here is an OS X StartupItem for memcached...

/Library/StartupItems/Memcached/StartupParameters.plist



{

  Provides        = ("Memcached");

  Description     = "Memcache Daemon";

  Uses            = ("Network");

  OrderPreference = "None";

}

/Library/StartupItems/Memcached/Memcached



#!/bin/bash

#

# /Library/StartupItems/Memcached/Memcached

#

# Script to startup memcached with OS X. Tested on 10.4 Tiger

#

# To enable, copy this file and StartupParameters.plist to

# /Library/StartupItems/Memcached and add "MEMCACHED=-YES-"

# to /etc/hostconfig ... You can then reboot or execute 

# "sudo /sbin/SystemStarter start Memcached" from a terminal

# to start it up.

#

# I should mention that this file uses my preferred development 

# settings. You can edit them before copying this script over 

# or they can be overriden by creating a config file named 

# memcached.conf in /etc, /opt/etc, or /usr/local/etc with the 

# following contents (modified to suit, of course):

#

#   MEMCACHED_EXE=/usr/local/bin/memcached

#   MEMCACHED_PIDFILE=/var/run/memcached.pid

#   MEMCACHED_MAX_MEM=128

#   MEMCACHED_INTERFACE=127.0.0.1

#   MEMCACHED_PORT=1121

#   MEMCACHED_RUN_AS=nobody 

#

# ------------------------------------------------------------------- 

# NOTE: Memcached < 1.2.0 has issues specifying the interface via the

# '-l' switch on the Mac for some reason so if the service fails to 

# start with the following error:

#

#    bind(): Can't assign requested address

#    failed to listen

#

# then you will need to either upgrade to version 1.2.0+ or forgo

# specifying an interface to listen on by removing the references

# to A_INTERFACE on lines 65 and 75 of this script. 

# -------------------------------------------------------------------

# Suppress the annoying "$1: unbound variable" error 

if [ -z $1 ] ; then

  echo "Usage: $0 [start|stop|restart] "

  exit 1

fi

test -r /etc/rc.common || exit 1

This code was inspired by Peter's code from May 17...

I basically extended his idea to be more flexible and added ! methods to modify the string in place. I chose to use a different regex selector because using "\b" breaks on apostrophes and leave you with words like "You'Re" instead of "You're"...





class String



  def titlecase()

    ignore_list = %w{of etc and by the for on is at to but nor or a via}

    capitalize_all_ex(ignore_list)

  end



  def titlecase!()

    ignore_list = %w{of etc and by the for on is at to but nor or a via}

    capitalize_all_ex!(ignore_list)

  end



  def capitalize_all(force_downcase = true)

    ignore_list = %w{}

    capitalize_all_ex(ignore_list, force_downcase)

  end



  def capitalize_all!(force_downcase = true)

    ignore_list = %w{}

    capitalize_all_ex!(ignore_list, force_downcase)

  end



  def capitalize_all_ex(ignore_list, force_downcase = true)

    # if force_downcase is true then the 

    # string is, um, downcased first :-)

    if force_downcase

      self.downcase.gsub(/[\w\']+/){ |w| 

        ignore_list.include?(w) ? w : w.capitalize  

      }

    else

      self.gsub(/[\w\']+/){ |w| 

        ignore_list.include?(w) ? w : w.capitalize  

      }

    end

  end



  def capitalize_all_ex!(ignore_list, force_downcase = true)

    if force_downcase

      self.replace(self.downcase.gsub(/[\w\']+/){ |w| 

        ignore_list.include?(w) ? w : w.capitalize  

      })

    else

      self.replace(self.gsub(/[\w\']+/){ |w| 

        ignore_list.include?(w) ? w : w.capitalize  

      })

    end

  end

end
