FCM Digital - Elixir Technical challenge

Development

Fcm-Challenge is written in Elixir 1.14.3, over Erlang 25 running on top of Docker compose (it can be installed using brew).

git clone https://github.com/jgtomas/fcm.git
cd fcm

# build
docker compose build

# Run the console container
docker compose exec fcm_challenge sh

And you're ready to test it! 🚀

# Inside beam container
mix test
# or one command
docker compose exec fcm_challenge mix test

Oh! Wait! One last thing 👀 If you want to execute the exercise, you just have to:

docker compose exec fcm_challenge mix run -e "Fcm.start('test/fixtures/file_1.txt')"

Notes

We have chosen for a solution which consists of transforming the unstructured data (text file) into a structured format (fcm/struts/traveler.ex) , this helps us to filter/group/order more easily.

• We always expect a plain text file (no pdf, docx..)
• We always expect the header of the file to be the BASED:
• We always expect a single BASED: (no multiples based in file)
• If the label is different from hotel,flight or train we show a custom message in the console output but without throwing an exception (we have another alternative, which would be to discard the segment)
