Compiled with GHC version 9.4.7

Running

Setup

stack install && stack build

Example Run Cmd

stack run './network.txt' 6

Unit tests can be run with

stack test artificial-script:unit-tests  

I have also included the compiled binary as well (network).

Known Issues

The optional expressions statement allows any content after the percentage, but prevents further parsing. For example

I1: 50% gibberish
I2: 60% if I1

will only parse I1: 50%.

Outstanding options

• Add to parser test suite
• Parser is currently strict on whitespace. This could be relaxed.
• Add validation of parsed network for logical consistency
  • Check all Expression Insurers exist
  • Check for impossible Expressions such as <5 with >5 or =4 with =5

Notes

I had never used a parsing library (other than aeson) prior to this task. As such I created a manual parser first to ensure I had something to submit. Then I wrote a method using megaparsec to try a more elegant and robust solution.
