Crate chatpack 

chatpack

Compress chat exports from Telegram, WhatsApp, and Instagram into token-efficient formats for LLMs.

Quick Start

use chatpack::prelude::*;

// Parse a Telegram export
let parser = create_parser(Source::Telegram);
let messages = parser.parse("chat.json").unwrap();

// Merge consecutive messages from same sender
let merged = merge_consecutive(messages);

// Filter by date or sender
let config = FilterConfig::new()
    .after_date("2024-01-01").unwrap()
    .with_user("Alice".to_string());
let filtered = apply_filters(merged, &config);

Using Individual Parsers

use chatpack::parsers::{TelegramParser, WhatsAppParser, InstagramParser, ChatParser};

let telegram = TelegramParser::new();
let messages = telegram.parse("result.json").unwrap();

let whatsapp = WhatsAppParser::new();
let messages = whatsapp.parse("chat.txt").unwrap();

Output Formats

use chatpack::prelude::*;

let messages = vec![InternalMessage::new("Alice", "Hello!")];
let config = OutputConfig::new().with_timestamps();

// Write to different formats
write_csv(&messages, "output.csv", &config).unwrap();
write_json(&messages, "output.json", &config).unwrap();
write_jsonl(&messages, "output.jsonl", &config).unwrap();
