Screen Shot - Ruby

Hiroto,

Awhile back you posted this script, but no longer works with Yosemite, can you post the needed edit?

#!/bin/bash


# screenshot area
x=0
y=0
w=$((1365-$x))
h=$((767-$y))


OSXver=$(sw_vers -productVersion)
if [[ $OSXver < "10.9" ]]; then 
    ruby="/usr/bin/ruby"
else
    ruby="/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby"
fi


$ruby <<-'END' - "$x" "$y" "$w" "$h"
require 'osx/cocoa'
include OSX
raise ArgumentError, "Usage: #{File.basename($0)} x, y, w, h" unless ARGV.length == 4
x, y, w, h = ARGV.map {|a| a.to_f}
outfile = File.expand_path(%x[date +'%F %H.%M.%S.png'].chomp, '~/Desktop')
img = CGDisplayCreateImageForRect(CGMainDisplayID(), CGRectMake(x, y, w, h))
brep = NSBitmapImageRep.alloc.initWithCGImage(img)
data = brep.objc_send(
    :representationUsingType, NSPNGFileType,
    :properties, {})
data.objc_send(
    :writeToFile, outfile,
    :atomically, false)
END

OS X Yosemite (10.10)

Tony,

Apple dropped the Ruby/Cocoa Scripting Bridge in Mavericks and Yosemite. If you install the OpenSource Ruby Cocoa v1.2.0, this script will then resume working, unless there is a Ruby version issue.

Hi,

On Maverick, the current version of ruby is 2.0, when i run the script --> `require': cannot load such file -- osx/cocoa (LoadError)

I can run your script with ruby version 1.8

On Yosemite, open the '/System/Library/Frameworks/Ruby.framework/Versions/' folder.

if the "1.8" folder exists, you can use this script :

#!/bin/bash
# screenshot area
x=0
y=0
w=$((1365-$x))
h=$((767-$y))

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby <<-'END' - "$x" "$y" "$w" "$h"
require 'osx/cocoa'
include OSX
raise ArgumentError, "Usage: #{File.basename($0)} x, y, w, h" unless ARGV.length == 4
x, y, w, h = ARGV.map {|a| a.to_f}
outfile = File.expand_path(%x[date +'%F %H.%M.%S.png'].chomp, '~/Desktop')
img = CGDisplayCreateImageForRect(CGMainDisplayID(), CGRectMake(x, y, w, h))
brep = NSBitmapImageRep.alloc.initWithCGImage(img)
data = brep.objc_send(
    :representationUsingType, NSPNGFileType,
    :properties, {})
data.objc_send(
    :writeToFile, outfile,
    :atomically, false)
END

Hello Tony T1,

Under OS X 10.10, you need to manually install RubyCocoa 1.2.0 which supports Ruby 2.0 or later.

http://rubycocoa.sourceforge.net/

http://sourceforge.net/projects/rubycocoa/files/RubyCocoa/1.2.0/

and change ruby interpreter in script to:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby

Regards,

Hiroto

PS. [[ "10.10" < "10.9" ]] is evaluated as true in shell. So the version test code, if necessary, needs to be changed... Perhaps using BuildVersion instead of ProductVersion?

Hiroto,

Just for clarity, RubyCocoa 1.2.0 does not install its own Ruby interpreter. The following Ruby binaries have matching identical checksums, and versions (2.0.0p481, release 45883) on OS X 10.9, and 10.10.3 respectively. They are the same binaries. RubyCocoa v1.2.0 enables the default System Ruby to again use the Ruby/Cocoa frameworks with its re-added scripting bridge support.

/usr/bin/ruby
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby

Mavericks disabled the Ruby/Cocoa bridge unless one used the following alternative. Yosemite removed this version entirely.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

The collating sequence makes the sw_vers -buildVersion a good choice for string comparison. The addition of RubyCocoa 1.2.0 in Mavericks, or Yosemite allows one to simply use the default system Ruby 2.0, while Mountain Lion and earlier require the Ruby 1.8 release per the previous bullet.
