2.1 Remove tabutil reference 🔇 to aviod runtime errors

• Move/Remove tabutil.rb file:

mv common/ruby/lib/tabutil.rb common/ruby/lib/tabutil.rb_old

• update code to remove reference from dump_reporter.rb

vim common/ruby/lib/dump_reporter.rb

#change ---
#require 'tabutil'
#----
class DumpReporter
  def initialize(app_name, log_dir, exit_on_exception)
  #changes ---
    #Tabutil::Tabutil.setup_fault_reporting(log_dir.to_s.gsub('/', '\\'),
    #                                       app_name, true, exit_on_exception)
    #ObjectSpace.define_finalizer(self, lambda { Tabutil.destroy_fault_reporting })
  # -----
  end

  def self.setup(app_name, log_dir, exit_on_exception)
    $dump_reporter = DumpReporter.new(app_name, log_dir, exit_on_exception)
  end

  def self.force_crash
  # changes ----
    #Tabutil.force_fault
  # ------
  end
end

2.2 Update code to change working directory (relative_path.rb)

vim ./common/ruby/lib/relative_path.rb

## when invoked via tablaunchjava, the current-working-directory may (likely) be different that where the user invoked tabcmd
## This Module and helper-routine can fixup relative paths to be from the original launch-dir
module RelativePath
  def self.fix_path(incoming)
    return nil unless incoming
    p = Pathname.new(incoming)
    return incoming if p.absolute?
    # change ----
    #tableau_working_dir = java.lang.System.get_property("tableau.working.dir")
    tableau_working_dir = "."
    # ------
    if tableau_working_dir
      return File.expand_path(incoming, tableau_working_dir)
    end
    return incoming
  end
end

2.3 Create environemnt variable

export APPDATA=~/Documents/tableau_for_centos/tabcmd_jar/tabcmd

• change Gemfile

copy gem file from tableau_for_centos/tabcmd_jar/tabcmd

• Execute bundle to install required gems

bundle install 
#if fails 
bundle update

• Install gems for safty, if is not installed duing bundle: 🙈

gem install log4r --no-document
gem install rchardet --no-document
gem install iconv --no-document
gem install rails --no-document

3. Run tabcmd:

bin/tabcmd.rb login -U <user_name> -s <server_url>

Error while running tabcmd.rb ‼️ :

/tabcmd/lib/server_info.rb:1: unknown encoding name: raw-text (ArgumentError)

solution: remove line 1 from server_infor.rb

uninitialized constant ActiveSupport::Autoload (NameError)

solution: add require 'active_support' to bin/tabcmd.rb
