## Joining BookWyrm
BookWyrm is still a young piece of software, and isn't at the level of stability and feature-richness that you'd find in a production-ready application. But it does what it says on the box! If you'd like to join an instance, you can check out the [instances](https://github.com/mouse-reeve/bookwyrm/blob/main/instances.md) list.
You can request an invite to https://bookwyrm.social by [email](mailto:mousereeve@riseup.net), [Mastodon direct message](https://friend.camp/@tripofmice), or [Twitter direct message](https://twitter.com/tripofmice).
## Contributing
There are many ways you can contribute to this project, regardless of your level of technical expertise.
### Feedback and feature requests
Please feel encouraged and welcome to point out bugs, suggestions, feature requests, and ideas for how things ought to work using [GitHub issues](https://github.com/mouse-reeve/bookwyrm/issues).
### Code contributions
Code contributions are gladly welcomed! If you're not sure where to start, take a look at the ["Good first issue"](https://github.com/mouse-reeve/bookwyrm/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) tag. Because BookWyrm is a small project, there isn't a lot of formal structure, but there is a huge capacity for one-on-one support, which can look like asking questions as you go, pair programming, video chats, et cetera, so please feel free to reach out.
If you have questions about the project or contributing, you can set up a video call during BookWyrm ["office hours"](https://calendly.com/mouse-reeve/30min).
### Translation
Do you speak a language besides English? BookWyrm needs localization! If you're comfortable using git and want to get into the code, there are [instructions](#working-with-translations-and-locale-files) on how to create and edit localization files. If you feel more comfortable working in a regular text editor and would prefer not to run the application, get in touch directly and we can figure out a system, like emailing a text file, that works best.
### Financial Support
BookWyrm is an ad-free passion project with no intentions of seeking out venture funding or corporate financial relationships. If you want to help keep the project going, you can donate to the [Patreon](https://www.patreon.com/bookwyrm), or make a one time gift via [PayPal](https://paypal.me/oulipo).
## About BookWyrm
### What it is and isn't
BookWyrm is a platform for social reading! You can use it to track what you're reading, review books, and follow your friends. It isn't primarily meant for cataloguing or as a data-source for books, but it does do both of those things to some degree.
### The role of federation
BookWyrm is built on [ActivityPub](http://activitypub.rocks/). With ActivityPub, it inter-operates with different instances of BookWyrm, and other ActivityPub compliant services, like Mastodon. This means you can run an instance for your book club, and still follow your friend who posts on a server devoted to 20th century Russian speculative fiction. It also means that your friend on mastodon can read and comment on a book review that you post on your BookWyrm instance.
Federation makes it possible to have small, self-determining communities, in contrast to the monolithic service you find on GoodReads or Twitter. An instance can be focused on a particular interest, be just for a group of friends, or anything else that brings people together. Each community can choose which other instances they want to federate with, and moderate and run their community autonomously. Check out https://runyourown.social/ to get a sense of the philosophy and logistics behind small, high-trust social networks.

## Setting up the developer environment
Set up the environment file:
``` bash
cp .env.example .env
```
For most testing, you'll want to use ngrok. Remember to set the DOMAIN in `.env` to your ngrok domain.
You'll have to install the Docker and docker-compose. When you're ready, run:
```bash
docker-compose build
docker-compose run --rm web python manage.py migrate
docker-compose run --rm web python manage.py initdb
docker-compose up
```
Once the build is complete, you can access the instance at `localhost:1333`
### Editing static files
If you edit the CSS or JavaScript, you will need to run Django's `collectstatic` command in order for your changes to have effect. You can do this by running:
``` bash
./bw-dev collectstatic
```
### Working with translations and locale files
Text in the html files are wrapped in translation tags (`{% trans %}` and `{% blocktrans %}`), and Django generates locale files for all the strings in which you can add translations for the text. You can find existing translations in the `locale/` directory.
The application's language is set by a request header sent by your browser to the application, so to change the language of the application, you can change the default language requested by your browser.
#### Adding a locale
To start translation into a language which is currently supported, run the django-admin `makemessages` command with the language code for the language you want to add (like `de` for German, or `en-gb` for British English):
``` bash
./bw-dev makemessages -l <language code>
```
#### Editing a locale
When you have a locale file, open the `django.po` in the directory for the language (for example, if you were adding German, `locale/de/LC_MESSAGES/django.po`. All the the text in the application will be shown in paired strings, with `msgid` as the original text, and `msgstr` as the translation (by default, this is set to an empty string, and will display the original text).
Add your translations to the `msgstr` strings. As the messages in the application are updated, `gettext` will sometimes add best-guess fuzzy matched options for those translations. When a message is marked as fuzzy, it will not be used in the application, so be sure to remove it when you translate that line.
When you're done, compile the locale by running:
``` bash
./bw-dev compilemessages
```
You can add the `-l <language code>` to only compile one language. When you refresh the application, you should see your translations at work.
## Installing in Production
This project is still young and isn't, at the moment, very stable, so please proceed with caution when running in production.
### Server setup
- Get a domain name and set up DNS for your server
- Set your server up with appropriate firewalls for running a web application (this instruction set is tested against Ubuntu 20.04)
- Set up an email service (such as mailgun) and the appropriate SMTP/DNS settings
- Install Docker and docker-compose
### Install and configure BookWyrm
The `production` branch of BookWyrm contains a number of tools not on the `main` branch that are suited for running in production, such as `docker-compose` changes to update the default commands or configuration of containers, and individual changes to container config to enable things like SSL or regular backups.
Instructions for running BookWyrm in production:
- Get the application code:
`git clone git@github.com:mouse-reeve/bookwyrm.git`
- Switch to the `production` branch
`git checkout production`
- Create your environment variables file
`cp .env.example .env`
- Add your domain, email address, SMTP credentials
- Set a secure redis password and secret key
- Set a secure database password for postgres
- Update your nginx configuration in `nginx/default.conf`
- Replace `your-domain.com` with your domain name
- Run the application (this should also set up a Certbot ssl cert for your domain) with
`docker-compose up --build`, and make sure all the images build successfully
- When docker has built successfully, stop the process with `CTRL-C`
- Comment out the `command: certonly...` line in `docker-compose.yml`
- Run docker-compose in the background with: `docker-compose up -d`
- Initialize the database with: `./bw-dev initdb`
Congrats! You did it, go to your domain and enjoy the fruits of your labors.
### Configure your instance
- Register a user account in the application UI
- Make your account a superuser (warning: do *not* use django's `createsuperuser` command)
- On your server, open the django shell
`./bw-dev shell`
- Load your user and make it a superuser
```python
from bookwyrm import models
user = models.User.objects.get(id=1)
user.is_staff = True
user.is_superuser = True
user.save()
```
- Go to the site settings (`/settings/site-settings` on your domain) and configure your instance name, description, code of conduct, and toggle whether registration is open on your instance
## Book data
The application is set up to share book and author data between instances, and get book data from arbitrary outside sources. Right now, the only connector is to OpenLibrary, but other connectors could be written.
There are three concepts in the book data model:
- `Book`, an abstract, high-level concept that could mean either a `Work` or an `Edition`. No data is saved as a `Book`, it serves as shared model for `Work` and `Edition`
- `Work`, the theoretical umbrella concept of a book that encompasses every edition of the book, and
- `Edition`, a concrete, actually published version of a book
Whenever a user interacts with a book, they are interacting with a specific edition. Every work has a default edition, but the user can select other editions. Reviews aggregated for all editions of a work when you view an edition's page.
### Backups
Bookwyrm's db service dumps a backup copy of its database to its `/backups` directory daily at midnight UTC.
Backups are named `backup__%Y-%m-%d.sql`.
The db service has an optional script for periodically pruning the backups directory so that all recent daily backups are kept, but for older backups, only weekly or monthly backups are kept.
To enable this script:
- Uncomment the final line in `postgres-docker/cronfile`
- rebuild your instance `docker-compose up --build`
You can copy backups from the backups volume to your host machine with `docker cp`:
- Run `docker-compose ps` to confirm the db service's full name (it's probably `bookwyrm_db_1`.
- Run `docker cp <container_name>:/backups <host machine path>
