#erlang My thoughts on improving the CSV decoder/encoder led me to the idea of using the functionality of regular expressions. This would simplify some of the checks and data analysis would be greatly simplified. Unintentionally, I don’t have enough experience with regular expressions in Erlang yet. So I need to practice with the `re` [module](http://erlang.org/doc/man/re.html). For this purpose, I created a [new repository](https://github.com/rustkas/Introducing-Regular-Expressions-by-Erlang) in which I will post examples of working with the `re` module’s functionality. ---

Using property-based test functionality I simply have found a restriction in an Erlang library ([bert.erl](https://github.com/yuce/bert.erl)) and make that one even better. 🚀 [Previous page](https://forum.devtalk.com/t/journal-property-based-testing-with-proper-erlang-and-elixir/10607.md?page=2)
