addcom 1.0.2

a CLI tool for adding comments to your source code files

ADDCOM

addcom is a CLI source code documenter tool which provides coders with an easy way to add comments to their source code files. Give it a relative/absolute path to your file and it will analyze its contents and add comments using a Large Language Model's chat completion.

See a demo of the functionality on YouTube: addcom-demo

Setup Instructions

Prerequisites

Make sure Python is installed on your system (you can download it here: https://www.python.org/downloads/).

1. Install the tool using pip

pip install addcom

2. Default: Create an account and generate the API key here: https://console.groq.com/

By default, addcom uses the Groq API endpoint for chat completion. However, you can specify a custom endpoint using the --base-url or -u flag option. (If you do this, make sure to obtain an appropriate API key and specify the model supported by the chosen provider using the --model/ -m option).

3. Set the API key

To do this you can expose the API key to the terminal:

Command Prompt

set GROQ_API_KEY=your_api_key_here

PowerShell

$env:ADDCOM_API_KEY="your_api_key_here"

Bash

$env:ADDCOM_API_KEY="your_api_key_here"

provide the key using the --api-key/ a option flag or set the API key in the TOML file.

4. Run addcom.

 addcom [OPTIONS] FILE_PATH(S)...

Configuration via TOML file

You can specify your preferred settings for the CLI tool by creating and editing a TOML configuration file. It will allow you to customize the default options to tailor the tool's behaviour to your needs. Learn more about TOML on the official website.

Important!: This will only work if you put addcom_config.toml in your home directory.

The supported arguments as of now are:

• model - specify the LLM to be used.
• stream - allow continous printing of model outputs as they are generated (can be set to "true" or "false").
• api_key - specify the api_key to be used for the API.
• context - path to the context file (provide the LLM with the commented file to base the comment style off of)

Windows Path Handling: When specifying the location of the context file, using standard Windows path single backslashes () can cause parsing errors, as tomllib treats those as escape characters. Windows users should specify paths with double backslashes (e.g., context = "examples\commented.py" instead of context = "examples\commented.py").

A sample configuration file config.toml.example is provided in the repository.

To create your own configuration file, run the following command:

cp config.toml.example ~/addcom_config.toml

Usage

Arguments

You can add comments to one or multiple source code files. Just type addcom and specify the file paths.

 addcom examples/sample.py examples/test.py

Options

Option	Shortcut	Type		Default
--help		FLAG	Show help message	N/A
--version	-v	FLAG	See the current tool version	N/A
--context	-c	PATH	Path to example file to provide context for the LLM	None
--output	-o	PATH	Specify an ouput filename to save the commented code	None
--stream	-s	FLAG	Stream the response live as it updates	None
--api-key	-a	TEXT	Provide API key for authentication	None
--base-url	-u	TEXT	Specify base URL for the API	None
--model	-o	TEXT	Specify a LLM to use for comment generation	None

Notes

Providing CLI options will override the default TOML settings.

--output / -o - If multiple files are specified, the commented source code from all files will be combined and saved into a single output file.

--api-key / -a - As mentioned above, there are 3 ways to provide the API key to the tool, passing the API key using this option will override the API key that was exposed to the terminal/the API key set in the TOML.

--model/ -m - You can find models compatible with the default API endpoint here: https://console.groq.com/docs/models

--base-url / u - If you decide to use a custom API endpoint, make sure to obtain an API key and specify a Large Language Model supported by the API of your choice.

Example: using OpenRouter API as base URL

 addcom -u https://openrouter.ai/api/v1 -a "your_api_key" -m meta-llama/llama-3.1-8b-instruct:free examples/test.py
