Assignment: You will write two small ruby applications in this assignment. First, write a simple application that convert a TSV (tab separated data file) into a YAML file. Second, write a simple application converts a YAML file back into a TSV file. Take a look at the two files called programmers_survey_2014.* to see examples of these two file formats. As you might guess, this is data from SOA students in 2014.

1. TSV to YAML:

Create an application file: tsv_to_yml.rb This file should have a script that converts a TSV file into a YAML file. Your YAML output should be saved into a YAML file of the user's choosing. Let your Ruby program takes the name of input and output files from command line parameters:

You would run it like this:

$ ruby tsv_to_yml.rb programmers_survey_2014.tsv outfile.yml

You can access command line parameters using the ARGV array (ARGV[0], ARGV[1]).

If the user does not supply an output filename, please print output to screen.

If you have done this correctly, each student in your output should look something like:

- date: 9/12/2014 20:20:55
 student_id: '1634'
 languages: 'Java, C , HTML , JavaScript , '
 best_language: Java
 app_experience: Native GUI applications, Web Applications, ...
 tech_experience: Unix-based OS, Database, Regular Expressions, Web Design

You must submit your ruby file as a Gist URL (use gist.github.com).

2. YAML to TSV:

Create another application that can converts a YAML skills file into a TSV file. You would run it like this:

$ ruby yml_to_tsv.rb programmers_survey_2014.yml outfile.tsv

Your generated TSV file should have the correct header information in the top row.

You must submit your ruby file as a Gist URL (use gist.github.com).

3. Testing

Throughout your coding, you should run automated tests on your code, you may do the following from command line, in the directory with all the files:

$ bundle install
(only need to run this once; bundle should report success)

$ ruby serializer_spec.rb
Run options: --seed 22740
