Hi @tsunghsienlee, @adnanaziz, @metopa

I have submitted a PR to outline my fix for issue #151.

Please review the same at your convenience and I will address any concerns with the same in the PR

[tsunghsienlee]

Generally it looks good to me, and I probably will omit get_strings function but it is definitely personal choice. This will be merge later.

Hi @tsunghsienlee

Hope you are doing well. I just saw that this PR has been sitting in an open state since a few months now. May I know when do you plan to merge this PR to master?

@deveshks Hi there, sorry for the long wait. I'll check this out right after I do my state exams at the end of June. I'll keep you updated :)
