# Hedgedoc Migrator

Simple script to migrate content from one Hedgedoc instance to another.

## Cypress


Follow the guide over [here](https://docs.cypress.io/guides/getting-started/installing-cypress#Linux-Prerequisites).

You also require NodeJS. Run `npm ci` to install the required packages.

### Execution

To start cypress, simply execute `npx cypress open`. Then click `E2E Testing` and run using electron. This step could be automated using the `cypress` [API](https://docs.cypress.io/guides/guides/module-api).


## Python

Create new python venv:
```
python -m venv venv
```

Activate the new environment (linux)

```
source venv/bin/activate
```

Install the requirements
```
pip install -r requirements.txt
```

### Execution

Start the extractor
```
python hedgedoc-image.py --replace new_netloc meta_pad1 meta_pad2 ...
```

For example:
```
python hedgedoc-image.py --replace pad.hacknang.de https://md.margau.net/dbk-meta
```

### Produced files

The python scripts produces a `pads.json` which contains the mapping from `old_url` to `new_url`.
All images land in `images/uploads`. Only images hosted on the `old_pads` URL are saved
