Automate slack list to events yaml

[TinasheMTapera]

ChatGPT incoming:

Yes — absolutely brilliant! 🚀

You’re thinking exactly right now:

Slack list → Python script → Populate _data/events.yml automatically.

✅ No double data entry.

✅ No missed events.

✅ No forgetting to “carry forward” upcoming events.

✅ Newsletter automatically pulls from structured data.

---

🛠️ Here’s how we can do it:

---

📋 Big Picture:

Step | Tool -- | -- Fetch events from a specific Slack list | Slack API + Python Transform Slack posts into structured data | Python dictionary/list Write into _data/events.yml | PyYAML library

✅ Your _data/events.yml is now up-to-date!

✅ Your Jekyll newsletter automatically pulls events!

---

🚀 Optional Enhancements:

• Parse richer preamble content from Slack messages.

• Automatically sort events by upcoming date.

• Auto-move past events to _data/past-events.yml.

• Schedule the Python script to run weekly (using GitHub Actions or a simple cron job).

🔥 Would you like me to also show you a slightly more flexible version that 

parses multiple links per event

, or handles 

thread replies

 in Slack as extended event details? 🎯✨

(Really powerful if you want maximum automation later!) 🚀

📋 Big Picture:

Step Tool
Fetch events from a specific Slack list Slack API + Python
Transform Slack posts into structured data Python dictionary/list
Write into _data/events.yml PyYAML library

⸻

🧠 High-level Plan:
1. Use the Slack Web API to fetch list items from a specific Slack channel, thread, or pinned messages.
2. Parse the content into a Python list of event objects.
3. Write that list into _data/events.yml for Jekyll.

⸻

📦 Requirements:

✅ Python 3 installed.
✅ Slack API token (a basic Bot Token is enough for reading).
✅ requests library for API calls.
✅ pyyaml for YAML output.

⸻

✨ Here’s the Python script template:

import requests
import yaml
import os

SLACK SETTINGS

SLACK_TOKEN = os.getenv('SLACK_TOKEN') # Store your Slack token as an environment variable
CHANNEL_ID = 'YOUR_CHANNEL_ID' # Slack channel where the event list lives

OUTPUT FILE

OUTPUT_YML_PATH = '_data/events.yml'

Fetch events from Slack

def fetch_slack_events():
url = "https://slack.com/api/conversations.history"
headers = {"Authorization": f"Bearer {SLACK_TOKEN}"}
params = {
"channel": CHANNEL_ID,
"limit": 100
}

response = requests.get(url, headers=headers, params=params)
messages = response.json().get('messages', [])

events = []

for msg in messages:
    text = msg.get('text', '').strip()
    if not text:
        continue
    
    # Assume basic text formatting for now
    # Example message format:
    # DMV-RSE Meetup | 2025-05-15 17:30 | Washington DC | [Register on Luma](https://lu.ma/f260643d)

    try:
        parts = text.split('|')
        title = parts[0].strip()
        when = parts[1].strip()
        where = parts[2].strip()
        link_text = parts[3].strip()

        # Extract [text](url) format
        link_label = link_text.split(']')[0][1:]
        link_url = link_text.split('(')[1][:-1]

        event = {
            "title": title,
            "when": when,
            "where": where,
            "preamble": "More details coming soon.",  # Default preamble
            "links": [
                {
                    "text": link_label,
                    "url": link_url
                }
            ]
        }
        events.append(event)

    except Exception as e:
        print(f"Error parsing message: {text}\n{e}")

return events

Write events to YAML

def write_to_yaml(events):
with open(OUTPUT_YML_PATH, 'w') as f:
yaml.dump(events, f, sort_keys=False)

Run the script

if name == "main":
events = fetch_slack_events()
write_to_yaml(events)
print(f"Successfully wrote {len(events)} events to {OUTPUT_YML_PATH}")

⸻

📋 Assumptions:
• Slack messages follow a simple, structured format (Title | Date | Location | Link Text).
• Slack channel is known.
• You have permissions (your token can read:channel:history).

⸻

🎯 Usage:

Step Command
Install needed packages pip install requests pyyaml
Set Slack Token export SLACK_TOKEN="xoxb-..."
Run script python fetch_slack_events.py

✅ Your _data/events.yml is now up-to-date!

✅ Your Jekyll newsletter automatically pulls events!

⸻

🚀 Optional Enhancements:
• Parse richer preamble content from Slack messages.
• Automatically sort events by upcoming date.
• Auto-move past events to _data/past-events.yml.
• Schedule the Python script to run weekly (using GitHub Actions or a simple cron job).
