Exercism F# representer

A representer creates a general representation of a submission, in order to automatically give feedback on similar code.

This repository contains the F# representer, which implements the representer interface. It uses F# Compiler Services to parse the submission's source code into syntax trees, which are then normalized and output as a representation.

Generate a representation for a solution

To create a representation of a solution, follow these steps:

1. Open a command prompt in the root directory.
2. Run ./generate.ps1 <exercise> <input-directory> <output-directory>. This script will generate a representation for the solution found in <input-directory>.
3. Once the script has completed, the representation will be written to <output-directory>/representation.txt.

Generate a representation for multiple solutions

To create representations for multiple solutions at once, follow these steps:

1. Open a command prompt in the root directory.
2. Run ./generate-in-bulk.ps1 <exercise> <input-directory>. This script will create a representation for the solution in each directory sub-directory of <input-directory>.
3. Once the script has completed, a representation for the solutions will be written in each directory.

Generate a representation for a solution using Docker

To generate a representation for a solution using a Docker container, follow these steps:

1. Open a command prompt in the root directory.
2. Run ./generate-in-docker.ps1 <exercise> <input-directory> <output-directory>. This script will:
   1. Build the representer Docker image (if necessary).
   2. Run the representer Docker image (as a container), passing the specified exercise, input-directory and output-directory arguments.
3. Once the script has completed, the representation can be found at <output-directory>/representation.txt.

Source code formatting

This repository uses the fantomas and prettier tools to format the source code. There are no custom rules; we just use the default formatting. You can format the code by running the ./format.ps1 command.

Scripts

The scripts in this repository are written in PowerShell. As PowerShell is cross-platform nowadays, you can also install it on Linux and macOS.
