Syntax errors with parsing CSV file with headers

Question

I am using ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux] where I am trying to test a script. The following does not work as expected

CSV.foreach(tscm_hosts_file, headers: tscm_hosts_file_col_headers) do |row|
  catch :bad_data do
    tscm_hosts_file_col_headers.each do |header|
      throw :bad_data if row[header].nil?
    end
.
.....

And error received is

[root@fmsprdchef001 ~]# ./generate_autoreg_output.rb
./generate_autoreg_output.rb:75: syntax error, unexpected ':', expecting ')'
...each(tscm_hosts_file, headers: tscm_hosts_file_col_headers) ...

I think this is the because of the ruby version I am using. Can someone tell which RUby version supports this syntax?

Move from

CSV.foreach(tscm_hosts_file, headers: tscm_hosts_file_col_headers)

to

CSV.foreach(tscm_hosts_file, :headers => tscm_hosts_file_col_headers)

The new hash syntax for symbols has been introduced in Ruby 1.9

so to use the existing script I should move to 1.9 ?

Yes, for that syntax you need at least ruby 1.9. Is that script a gem, just a file you have or what?

codec Over a year ago

Its just a .rb file

You can either use ruby 1.9 or fix that file to the old syntax. But other changes could be needed.

@aaj if changing ruby versions is an option you should do it even 1.9 has been out of support for quite some time
