Real world example

Remote server setup and configuration

consts = “dns = 'ec2-127.0.0.1.amazon.com‘; file = ‘app.config’” command = “contents = System::IO::File.read_all_text(file); " + "contents = contents.replace(‘$(MACHINE_DNS)', dns); " + "System::IO::File.write_all_text(file, contents)"

ir.exe -e ”#{consts}” -e ”#{command}”

ir.exe installed onto every server via svn+teamcity

Ruby as a scripting language

require 'win32ole'excel = WIN32OLE.new("excel.application")excel['Visible'] = true

#Create a new sheetworkbook = excel.Workbooks.Addexcel.Range("a1")['Value'] = 3excel.Range("a2")['Value'] = 2excel.Range("a3")['Value'] = 1excel.Range("a1:a3").Select

# Add a chartexcelchart = workbook.Charts.AddXL3D_COLUMN_CHART_TYPE = -4100excelchart['Type'] = XL3D_COLUMN_CHART_TYPE

Built-in to IronRuby & Excel
