# Showcode Forge

Tools for generating code for ShowCode Forge. ShowCode Forge is a community dedicated to creating challenges on [ShowCode](https://www.showcode.io/).

## Install

This tool requires Python 3.7+. You can download Python from [here](https://www.python.org/downloads/)

Install the latest release of the package from PyPi.

```sh
pip install showcode_forge
```

## Validate

Validating is ensuring that your challenge `.json` file is correct according to the ["Tome of Crafting"](https://bit.ly/3pXDMAp) (aka the how to guide). It verifies that you have all fields correctly filled out, that your unit tests match your parameters and return types and that your points add up.

How to run:

```sh
showcode_forge validate [--verbose] file
```

- `file` is a path ot the `.json` file
- `--verbose` enables additional logging. Without this, if there are no errors, the tool will not output anything

Example usage:

```sh
showcode_forge validate --verbose challenge.json
```

## Extract

Extracting is turning a challenge `.json` (provided by the community) into a set of files, including `question.html` and generated source and test files for your selected language.

How to run:

```sh
showcode_forge extract [--language LANGUAGE] [--framework FRAMEWORK] file
```

- `file` is a path to the `.json` file
- `LANGUAGE` is the selected programming language. Currently supported: `py`
- `FRAMEWORK` is the selected unit testing framework. Currently supported: `unittest`, `pytest`, `pytest_scforge` (see bellow), default: `unittest`

Example usage:

```sh
showcode_forge extract --language py --framework unittest challenge.json
```

## Compile

Compiling is turning a source, test and question files into a `.json` file.

How to run:

```sh
showcode_forge compile [--output OUTPUT] [--language LANGUAGE] [--framework FRAMEWORK] source_file test_file question_file
```

- `source_file` is a path to the solution file where the correct answer is defined
- `test_file` is a path to the file that defines unit tests
- `question_file` is a path to the file that defines the question rubric text (usually `.html`)
- `OUTPUT` is a path to where the output will be generated (default: `challenge.json`)
- `LANGUAGE` is the programming language `source_file` and `test_file` are written in. Currently supported: `py`
- `FRAMEWORK` is the unit testing framework used to define the test cases. Currently supported: `pytest_scforge` (see bellow)

Example usage:

```
showcode_forge compile --language py --framework pytest_scforge --output my_awesome_challenge.json solution.py tests.py question.html
```

### Using Pytest with ShowCode Forge

The current only supported compiler is a modified version of `pytest`. Here is how you would normally write a challenge using `pytest`:

```py
import pytest
from solution import Solution

@pytest.mark.parametrize(
    "count,expected_result",
    [
        (3, "1, 2, Fizz"),
        (7, "1, 2, Fizz, 4, Buzz, Fizz, 7"),
        (0, "")
    ]
)
def test_fizzbuzz(count, expected_result):
    s = Solution()
    assert s.fizzbuzz(count) == expected_result
```

You would run this, by running `pytest` in the command line.

With **ShowCode Forge** here is what the same test looks like:

```py
from showcode_forge import challenge, TestCase
from solution import Solution

@challenge(
    "count,expected_result",
    [
        TestCase([3], "1, 2, Fizz", "Simple public case", is_public=True),
        TestCase([7], "1, 2, Fizz, 4, Buzz, Fizz, 7", "More complex private case", points=2),
        TestCase([0], "", "Empty case", points=3)
    ]
)
def test_fizzbuzz(count, expected_result):
    s = Solution()
    assert s.fizzbuzz(count) == expected_result
```

This runs exactly the same if you run `pytest` in the command line. `@challenge` generates `pytest` test cases behind the scenes.

It uses the parameter declaration and the various test cases to infer parameter names and types. It automatically calculates the point total as well. If `points` is not specified, it defaults to 1. If `is_public` is not specified it defaults to `False`.

It does not support every field currently. You will have to manually edit the `.json` to set the `title`, `className` and `methodName`. `difficulty` is infered from total points, but can be updated.

## Scaffold

Scaffolding sets up the files needed to develop a challenge with the some starting boilerplate code in place.

How to run:

```sh
showcode_forge scaffold [-h] [--argument ARGUMENT [ARGUMENT ...]] [--result RESULT] [--output_dir OUTPUT_DIR] [--language LANGUAGE] [--framework FRAMEWORK] class_name method_name
```

 - `class_name` is the name of the tested class
 - `method_name` is the name of the tested method in the tested class
 - `ARGUMENT` is a list of argument names that the tested method takes
 - `RESULT` is the name of the result produced by the tested method
 - `OUTPUT_DIR` is the directory where the output is generated. If not specified, it will be generated in the current directory
 - `LANGUAGE` is the programming language the files will be generated in. Currently supported: `py`
 - `FRAMEWORK` is the unit testing framework used to define the test cases. Currently supported: `pytest_scforge` (see bellow)

Example usage:

```sh
python -m showcode_forge scaffold "ClassName" "solve_challenge" --argument "arg_1" "arg_2" "arg_3" --language py --framework pytest_scforge
```
