Incept

Incept is a small CLI for turning course outlines into a structured course payload, inserting that payload into your database (currently Notion), and (optionally) preparing a Jellyfin-friendly video folder hierarchy and downloading lesson videos (Rebelway).

This README is written for the “I’m adding a new course” workflow.

---

What you’ll run most often

1. Build the payload JSON from chapters.csv + lessons.csv
2. Add the course to Notion (optionally create Jellyfin folders + artwork)
3. Download the videos from Rebelway (from lessons.xlsx)

---

Install / first-time setup

1) Initialize user config (~/.incept)

incept init

This creates:

• ~/.incept/.env (copied from env.example if missing)
• ~/.incept/templates/
• ~/.incept/payload/
• ~/.incept/mapping/

2) Configure your .env

Edit:

nano ~/.incept/.env

At minimum you usually want:

• DATABASE_NAME=notion
• NOTION_API_KEY=...
• NOTION_COURSE_DATABASE_ID=...

(Your code will also accept --api-key / --database-id overrides, but most of the time .env is easiest.)

Workflow: add a new course

Step 0: Prepare inputs

You generally need:

• chapters.csv — course chapter list
• lessons.csv — lesson list with chapter_index
• For downloading videos: lessons.xlsx (sheet: lessons) with columns:
  • chapter_index
  • name
  • link

Note: the downloader currently reads Excel, not CSV.

1) Build the payload JSON

Command:

incept build-payload \
  --course-name "Coding Generative AI" \
  --course-desc "..." \
  --intro-link "https://rebelway.academy/lessons/welcome-83/" \
  --chapters ~/.incept/payload/chapters.csv \
  --lessons  ~/.incept/payload/lessons.csv \
  --chapter-name-template "Week {i:02d}" \
  --tool 166a1865-b187-8138-8316-dc8288897458 \
  --tool 149a1865-b187-80f9-b21f-c9c96430bf62 \
  --instructor "Felipe Pesantez" \
  --tags Houdini \
  --tags Python \
  --template default \
  --thumb-base-public-id "thumb/base_image" \
  --out ~/.incept/payload/coding_gen_ai.json

Notes:

• --tool, --instructor, --tags are repeatable flags.
• --range 2-4 will build only those chapters (useful for testing).
• --chapter-name-template "Week {i:02d}" formats the chapter names from chapter index.

2) Add the course (insert into Notion)

2a) Insert course (no Jellyfin folders/artwork)

incept add-course --data-file-path ~/.incept/payload/coding_gen_ai.json

2b) Insert + create Jellyfin video folder hierarchy (+ artwork)

incept add-course --data-file-path ~/.incept/payload/coding_gen_ai.json --include-video

What --include-video does (high level):

• Creates a Jellyfin-friendly folder structure
• Generates artwork (poster/thumb/logo/background)
• Stores the full episode paths in Notion (so Jellyfin + filesystem match)

---

3) Download all lesson videos (Rebelway)

This is driven by Excel (lessons.xlsx), not your CSV payload.

incept dl-rebelway \
  --excel  ~/.incept/mapping/lessons.xlsx \
  --output ~/Videos/rebelway/coding_gen_ai \
  --chrome-port 9222

Options:

• Skip initial rows (if your sheet has headers or you want to resume):

incept dl-rebelway --excel ~/.incept/mapping/lessons.xlsx --output ~/Videos/rebelway/coding_gen_ai --skip-first 10

• Download only one chapter (week):

incept dl-rebelway --excel ~/.incept/mapping/lessons.xlsx --output ~/Videos/rebelway/coding_gen_ai --range 3

• Download a chapter range:

incept dl-rebelway --excel ~/.incept/mapping/lessons.xlsx --output ~/Videos/rebelway/coding_gen_ai --range 2-4

How the downloader works (important)

• It launches Chrome with remote debugging (--chrome-port, default 9222)
• You log in manually, then hit ENTER in the terminal
• Selenium reads each lesson page and extracts the “SOURCE” MP4 from the download selector
• A requests session reuses your Chrome cookies and downloads the file

Troubleshooting

Font error when using --include-video

If you see:

OSError: cannot open resource

It means Pillow can’t open one of the font files used for artwork generation.

Your code currently loads fonts from a package-relative path:

<incept package dir>/.config/fonts/coresansc/

Common causes:

• Fonts folder is missing (not included in install)
• Filenames don’t match what the code expects:
  • coresansc35.otf
  • coresansc75.otf
  • coresansc25.otf

Quick checks:

python -c "import incept.asset_generator as a; from pathlib import Path; p=Path(a.__file__).parent/'.config/fonts/coresansc'; print('FONT_DIR=', p); print('exists=', p.exists()); print([x.name for x in p.glob('*')])"

Temporary workaround:

• Run without --include-video to insert the course first:

incept add-course --data-file-path ~/.incept/payload/coding_gen_ai.json

Recommended long-term fix (implementation idea):

• Move fonts to ~/.incept/fonts/coresansc and load from there, or
• Package fonts as data files and load via importlib.resources

“Downloader doesn’t find SOURCE”

If you get warnings like “No SOURCE found”, generate a report:

incept report-broken \
  --excel  ~/.incept/mapping/lessons.xlsx \
  --output ~/.incept/mapping/broken_sources.csv \
  --chrome-port 9222

Quick reference (cheat sheet)

Build payload

incept build-payload --course-name "..." --course-desc "..." --intro-link "..." --chapters chapters.csv --lessons lessons.csv --out payload.json

Insert course

incept add-course --data-file-path payload.json

Insert course + Jellyfin folders

incept add-course --data-file-path payload.json --include-video

Download videos (Rebelway)

incept dl-rebelway --excel lessons.xlsx --output /path/to/videos
