codeify 0.1

Python-based development utilities

Introduction

Codeify is a pure Python code-generation utility for accelerating development in any platform / environment.

Codeify's code generator processes an input directory and produces an output directory with similar structure along with the aid of a provided specification file and Jinja templates for generated outputs.

Usage

Codeify should be used for development-only purposes. This should not be tied into any critical processes and should be seen only as a tool to speed up development.

Example

Using a sample input directory with the following files:

spec.yaml

---
structs:
    Account:
        fields:
            id: { type: int }
            name: { type: std::string }

    CheckingAccount:
        fields:
            amount: { type: double }
        _extends: Account

    SavingsAccount:
        fields:
            amount: { type: double }
            interest_rate: { type: double }
        _extends: Account

main.cpp.j2

{% for name, value in structs.items() %}
#include "{{ name }}.h"
{% endfor %}

int main()
{
    // TODO: Implement
    return 0;
}

class.j2

#pragma once

namespace structs
{
    class {{ class_name }}{% if class_data._extends %} : {{ class_data._extends }}{% endif %}
    {
    private:
        {% for field_name, field in class_data.fields.items() %}
        {{ field.type }} {{ field_name }}_;
        {% endfor %}
    public:
        {% for field_name, field in class_data.fields.items() %}
        {{ field.type }} get{{ pascal_name(field_name) }}() const
        {
            return {{ field_name }}_;
        }

        void set{{ pascal_name(field_name) }}({{ field.type }} && value)
        {
            {{ field_name }}_ = std::move(value);
        }

        {% endfor %}
    };
}

.codeify

---
ignore: [ spec.yaml, class.j2 ]
generate:
{% for name, data in structs.items() %}
    {{ name }}.h:
        input: class.j2
        data:
            class_name: {{ name }}
            class_data: {{ data }}
{% endfor %}

You can then run Codeify on the input directory ($INPUT) specifying both an output directory ($OUTPUT) and a specification file ($INPUT/spec.yaml):

codeify -i $INPUT -o $OUTPUT -s $INPUT/spec.yaml

Your output directory ($OUTPUT) should now contain the following files:

• Account.h
• CheckingAccount.h
• SavingsAccount.h
• main.cpp

The three Account header files are generated from class.j2 specified through a directory context file (.codeify). main.cpp was generated from main.cpp.j2. These were all generated with the use of the spec.yaml file providing the inputs.
