pascal (/pæˈskæl/) named after Blaise Pascal, completing the duo with blaise. While blaise handles the heavy lifting of routing and pathfinding, pascal provides the human connection, acting as a smart interface for your daily commute.

pascal is a proactive, chat-based transit assistant. It integrates directly into your messaging apps (like Discord) to manage recurring trips, monitor your routes in real-time, and notify you exactly when it's time to leave, so you never have to check a timetable again.

Why pascal?

Most transit apps are passive; you have to open them, search, and stare at the screen. pascal flips this model by being an active assistant that lives where you already chat:

• Set and Forget: Define your routine once using natural language ("Work, 9 AM every weekday"), and pascal handles the rest.

• Proactive Alerts: Instead of you checking the time, pascal tells you: "Leave in 15 minutes" or "Stop coming up in 1 minute."

• Blaise Powered: Built on top of the blaise engine, ensuring that every route calculation is blazing fast, private, and local.

• Self-Hosted SaaS: Run it for your friends, your server, or your organization. You own the data and the infrastructure.

Core Features

• Natural Language Scheduling: Create complex recurring trips effortlessly. "Work, from: Home to: Office every day, arrival 08:00:00 except saturday and sunday"

• Real-Time Guidance: Continuous monitoring of your active trips with push notifications for departures, transfers, and arrivals.

[!NOTE] This project is both a SaaS solution and an experiment in human-centric interfaces for the blaise engine.

Installation

pascal is written in Go. You can build it from source:

git clone https://github.com/vincbro/pascal.git
cd pascal
go build -o pascal ./cmd/bot

Quick Start

1. Prerequisites: Ensure you have a running instance of the blaise server and a Discord Bot Token.

2. Configuration: Create a .env file in the root directory:

DISCORD_KEY=your_discord_bot_token
APP_ID=your_discord_app_id
GUILD_ID=your_discord_guild_id
BLAISE_URL=http://localhost:8080    

3. Run

./pascal

4. Usage: In your Discord server, use the slash command to find a route:

/new from: "Central Station" to: "Tech Park"

Roadmap

• Discord Bot integration with Slash Commands
• Basic routing via blaise client
• Natural Language Processing (NLP) for trip scheduling
• Job scheduler for recurring trip monitoring
• Real-time state tracking and push notifications
• Integration with other platforms (Slack, Telegram)
