Template Engine V2

Hello there! Thank you for using the Template Engine. Please review our commercial license for legal use and contact us at support@entinco.com for inquiries and clarification.

Overview

The Template Engine is a powerful tool designed to create software component skeletons from templates. This tool streamlines the process of creating complex software components by leveraging templates and advanced AI-based descriptions for increased precision.

Features

Template-based Skeleton Generation

• Copies a component template to a specified output directory and performs search & replace operations on targeted keywords.

AI-Powered Planning and Strategy Selection

• Utilizes OpenAI's GPT model to analyze specifications and determine the most effective strategy for each task.
• Automatically identifies dependencies and optimizes execution paths.
• Supports generative assistance to create new templates and components based on custom needs and specifications.

CLI with Flexible Options

• Offers intuitive command-line options for quiet, verbose, and replacement modes.
• Supports batch operations for repeatable processes, enabling automated workflows.
• Provides helpful error messages and usage hints for a smoother user experience.

Specification Handling

• Reads JSON-formatted specification files to guide the component generation process.
• Adapts dynamically based on user-provided descriptions and templates.
• Integrates structured and unstructured input to provide a robust understanding of the component structure.
• Supports .gitignore-style lists to skip unnecessary files and directories during generation.

Installation

Install this package from PyPI using the Python package installer (Pip):

pip install templateengine

Command-line Usage

To run the Template Engine, use the following command in your terminal:

templateengine [options]

General Arguments

• -h, --help: Displays available command-line arguments.

  • Type: Utility
  • Required: No

• --version: Displays the current version of the Template Engine.

  • Type: Utility
  • Required: No

Primary Parameters

• -t, --template: Specifies the folder or directory path where the component template is located.

  • Type: Required
  • Shorthand: -t

• -o, --output: Specifies the folder or directory path where the resulting component will be saved.

  • Type: Required
  • Shorthand: -o

Optional Parameters

• -g, --ignore: Specifies the file name or relative path in the template directory for a list of ignored keywords. By default, it looks for a .gitignore file.

  • Type: Optional
  • Default: .gitignore
  • Shorthand: -g

• -n, --name: Specifies a search and replacement keyword pair for renaming components. Can be repeated for multiple replacements.

  • Type: Optional but recommended
  • Shorthand: -n
  • Usage: --name=<old_name>:<new_name>
  • Example: --name=entity:product

• -v, --verbose: Enables verbose output for detailed information during execution.

  • Type: Optional
  • Shorthand: -v

• -q, --quiet: Mutes all output during execution. Overrides --verbose if both are present.

  • Type: Optional
  • Shorthand: -q

• -s, --spec: Specifies the file path to the component specifications file (in JSON format).

  • Type: Optional
  • Shorthand: -s
  • Description: This file guides the generation process and helps describe subcomponents in detail.

• -m, --model: Specifies the GPT model to use for AI-assisted generation.

  • Type: Optional
  • Default: gpt-4o
  • Shorthand: -m

OpenAI API Key

The Template Engine requires an OpenAI API key to use AI-assisted planning and component generation. The API key can be provided in two ways:

1. Environment Variable: Set the OPENAI_API_KEY in your system environment.

   export OPENAI_API_KEY=your_openai_api_key_here
   

   • Benefits: Automatically read during execution for convenience.

2. Manual Input: If the environment variable is not set, the Template Engine will prompt you to input the API key manually.

API Key Validation:

• The API key must be at least 20 characters long.
• If the key is invalid or missing, the program will terminate with an error code 4.

  Code 4 - Invalid or missing API key.
  

• Security Tip: Do not share or hard-code your API key in scripts to avoid unauthorized access.

Example Usage

Here's an example of running the Template Engine from the command line:

#!/usr/bin/env pwsh

templateengine \
--template=../../templates/backend/node/service-cruddata-pipservices \
--output=../../output/service-products-pipservices \
--name=cruddata:products \
--name=entity:product \
--name=entities:products \
--spec=specifications/description.json \
--verbose

InputParams Structure

The InputParams class stores all the key parameters passed to the Template Engine. Here is a breakdown of its attributes:

• command (str): Specifies the command to execute (e.g., create, extend, fix).
• template_dir (str): Directory path to the template being used.
• input_dir (str): Directory path to the input software component.
• output_dir (str): Directory path where the output software component will be saved.
• ignore_list (list): List of paths or filenames to ignore during template processing.
• replacements (list of dicts): List of search and replacement keyword pairs for renaming components.
  • Example: [{"search": "cruddata", "replace": "products"}]
• specs (dict): JSON-formatted specifications that guide the component generation process.
• quiet (bool): Whether to suppress all output.
• verbose (bool): Whether to display detailed execution logs.
• model (str): Specifies the GPT model to use (default: omni).
• api_key (str): OpenAI API key for accessing AI-powered features.
