# FSharp Journeys
A coding challenge based on the one defined by Mike Hadlow [github](https://github.com/mikehadlow/Journeys).
This implementation is entirely written in F# and it's a dotnet core 3.0 solution.
## Build on your machine
If you want to build this soltion, execute the following commands:
``` shell
git clone https://github.com/galassie/fsharp-journeys.git
cd fsharp-journeys
dotnet build
```
If you want to run the tests, execute the following command:
``` shell
dotnet test
```
## Run the console application
To run the application and see the output, execute the following commands from the root folder of the repository:
``` shell
cd ./src/FSharp.Journeys.Console
dotnet run
```
The journeys are defined in the input.txt file.
Most of those are correct:
``` shell
❗Start Journey n. 1❗
Initial robot state:
{ Position = Position (1, 1)
Direction = East }
Commands:
[TurnRight; MoveForward; TurnRight; MoveForward; TurnRight; MoveForward;
TurnRight; MoveForward]
Expected final robot state:
{ Position = Position (1, 1)
Direction = East }
Actual final robot state:
{ Position = Position (1, 1)
Direction = East }
Test result: PASS 🎉
```
I've also added two more wrong journeys to check the output (one with parsing errors and the other with mismatch expected-actual final robot state):
``` shell
❗️Start Journey n. 4❗️
Parsing error ⛔️
Failed to parse state -> Failed to parse direction: A
❗️Start Journey n. 5❗️
Initial robot state:
{ Position = Position (0, 3)
Direction = West }
Commands:
[TurnLeft; TurnLeft; MoveForward; MoveForward; MoveForward; TurnLeft;
MoveForward; TurnLeft; MoveForward; TurnLeft]
Expected final robot state:
{ Position = Position (2, 9)
Direction = East }
Actual final robot state:
{ Position = Position (2, 4)
Direction = South }
Test result: FAIL ❌
```
## Final notes
Suggestions on how to improve the code are more than welcome! 😊
I'm not by any means an F# expert so feel free to contact me or open PRs if you notice something that could have been done better!
