Installation Steps

From PyPI

pip install chatybot

From Source

# Clone the repository
git clone https://github.com/jon2allen/chatybot.git
cd chatybot

# Install in editable mode
pip install -e .

nano src/chatybot/chat_config.toml  # Add your API keys and model configurations

Troubleshooting

macOS Permission Denied Error (~/.config) On macOS, if you encounter a Permission denied error when chatybot attempts to access or create the ~/.config directory, it usually means the folder is owned by root or another user.

To fix this, take ownership of your .config directory by running this command in your terminal:

sudo chown -R $(whoami) ~/.config

If the directory does not exist at all and errors persist, you can create it and then set the ownership:

mkdir -p ~/.config
sudo chown -R $(whoami) ~/.config

Quick Start

# Start the chat interface
python3 chatybot.py

Advanced Features

File Handling

/file document.txt      # Load a file into the main buffer
/filebank1 notes.txt    # Load a file into file bank 1
/showfile all           # Show all loaded files
/clearfile              # Clear the main buffer

Prompt Engineering

/prompt template.txt    # Load a prompt template
/system "Act as a tutor" # Set system message

Scripting

Create a script file (setup.chatdsl):

set project = "chatbot"
if ${project} then /file ${project}_requirements.txt
wait 1
chat --> Generate documentation for this project

Execute the script:

/script setup.chatdsl

ChatDSL Validation

For automated validation of .chatdsl files, use the chatdsl_parse utility:

chatdsl_parse --file my_script.chatdsl

• Returns exit code 0 on successful parse.
• Returns exit code 1 on parse error or file error.
• Use the -v flag for verbose error output.

Database & Variable Integration (New!)

/setdb my_knowledge       # Open or create 'db/my_knowledge.json'
/searchdb "linked list"   # Search content, results stored in SEARCHBUFFER
/loadvar search_results   # Copy SEARCHBUFFER to ${search_results}
chat --> Explain these: ${search_results}
/dblog                    # Save the AI's explanation back to the database

Variable Substitution

Variables can be set manually, via search results, or in scripts:

/setvar username "Jon"
chat --> Hello ${username}, show me ${search_results}

Note: Script variables (/setvar) are for text substitution only. For image analysis with vision models, use image banks instead. Load images with /imagebank1 <file> and reference them with {imagebank1} syntax in your prompts. The {imagebank1} placeholder sends the image as a proper multimodal attachment, while ${var} substitution inserts text only.

Image Support (Beta)

chatybot supports text-to-image generation and image-to-text (vision) analysis for supported models. This feature is currently in Beta.

Image Output Directory

Generated images are saved to a date-organized directory structure:

~/chatybot_images/
└── YYYY-MM-DD/
    ├── prompt_001.png
    ├── prompt_002.png
    └── ...

Configuration:

• Default: ~/chatybot_images/ (set in chat_config.toml under [image_generation].default_dir)
• Override at runtime: /imagedir /custom/path/to/images
• Override in config: Edit default_dir in src/chatybot/chat_config.toml

Path Resolution:

1. Config file default_dir (if set)
2. Hardcoded fallback: ~/chatybot_images

Text-to-Image Generation

Generate images from text prompts using supported models (OpenAI, Mistral, Google, OpenRouter):

/model openrouter_image
/imagine "a red toyota corolla 1980s on a mountain road"

Supported Models:

• openrouter_image: Google gemini-2.5-flash-image (OpenRouter)
• flux_1: Flux.2 models (OpenRouter)
• mistral_1: Mistral image models
• gemini_flash, gemini_pro: Google image models

Image Size Options:

/imagesize 1024x1024      # Default
/imagesize 1920x1080      # Wide
/imagesize 1K            # Google format for gemini models

Image-to-Text (Vision) Analysis

Load images into image banks and query vision models:

/imagebank1 my_photo.jpg     # Load image into bank 1
/model openrouter_image     # Switch to vision model
Describe this image: {imagebank1}

Image Bank Commands:

Command	Description	Example
/imagebank{1-5} <file>	Load image into bank	/imagebank1 cat.jpg
/imagebank{1-5} clear	Clear an image bank	/imagebank1 clear
/imagebank{1-5} show	Show image bank info	/imagebank1 show

Conditional Logic

set debug = true
if ${debug} then /temp 0.1
if not ${debug} then /temp 0.7

Macro System (New!)

Chatybot now features a powerful macro system based on Parsley. Macros allow you to define reusable prompt templates with parameters.

Defining Macros (in src/chatybot/macro.chatdsl):

def expert(topic) = "You are an expert in {topic}. Provide detailed information about {topic}."
def compare(a, b) = "Compare {a} and {b} and discuss their differences."

Using Macros:

%expert(Python)
%compare("GPT-4", "Claude 3")

Macros can be called from the interactive prompt or within scripts. Inline variable substitution is supported in macro arguments: %expert(${current_topic}).

Test Cases

Test Case 1: Basic Command Execution

Input:

/model gpt4
/listmodels
/model

Expected: Switches to gpt4, lists models, shows current model.

Test Case 2: File Handling

Input:

/file test.txt
/showfile
/clearfile
/showfile

Expected: Loads file, shows content, clears buffer, shows empty buffer.

Test Case 3: Script Execution

Script (test_script.txt):

set project = "chatbot"
if ${project} then /file ${project}_requirements.txt
wait 1
/showfile

Input: /script test_script.txt Expected: Loads file, waits, shows content.

Test Case 4: Error Handling

Input:

/invalidcommand
/file nonexistent.txt

Expected: Shows error messages for invalid command and missing file.

===========================
Active model: mistral-large-2512 (alias: mistral_1)
chat --> /model nvidia_1
Switched to model: nvidia/nemotron-nano-12b-v2-vl:free (alias: nvidia_1)
chat --> create a C program that demonstrates a linked list
Here's a well-structured C program that demonstrates the implementation and usage of a **singly linked list**. This program includes basic operations such as:

- **Appending** elements to the end of the list.
- **Printing** the contents of the list.
- **Freeing** the memory allocated to the list to prevent memory leaks.

---

### C Program: Demonstrating a Singly Linked List

```c
#include <stdio.h>
#include <stdlib.h>

.............

This program provides a solid foundation for understanding and working with linked lists in C. You can expand upon it to implement more complex data structures or algorithms.


Execution time: 28.95 seconds
Input tokens: 29, Output tokens: 2509
chat --> /notemode on
Note mode enabled. Code blocks will be extracted when using /save.
chat --> /save demo_link_list.c
Last chat completion saved to 'demo_link_list.c'.
Note mode is ON. Processing file 'demo_link_list.c'...
