# Code of Conduct
- We are committed to providing a friendly, safe and welcoming environment for all, regardless of level of experience, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, nationality, or other similar characteristic.
- Please avoid using overtly sexual aliases or other nicknames that might detract from a friendly, safe and welcoming environment for all.
- Please be kind and courteous. There’s no need to be mean or rude.
- Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
- Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
- We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior. We interpret the term “harassment” as including the definition in the Citizen Code of Conduct; if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don’t tolerate behavior that excludes people in socially marginalized groups.
- Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel ops or any of the Lemmy moderation team immediately. Whether you’re a regular contributor or a newcomer, we care about making this community a safe place for you and we’ve got your back.
- Likewise any spamming, trolling, flaming, baiting or other attention-stealing behavior is not welcome.
[**Message the Moderation Team on Mastodon**](https://mastodon.social/@LemmyDev)
[**Email The Moderation Team**](mailto:contact@lemmy.ml)
## Moderation
These are the policies for upholding our community’s standards of conduct. If you feel that a thread needs moderation, please contact the Lemmy moderation team .
1. Remarks that violate the Lemmy standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.)
2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed.
3. Moderators will first respond to such remarks with a warning.
4. If the warning is unheeded, the user will be “kicked,” i.e., kicked out of the communication channel to cool off.
5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded.
6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology.
7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, in private. Complaints about bans in-channel are not allowed.
8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others.
In the Lemmy community we strive to go the extra step to look out for each other. Don’t just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they’re off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely.
And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could’ve communicated better — remember that it’s your responsibility to make others comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust.
The enforcement policies listed above apply to all official Lemmy venues; including git repositories under [github.com/dessalines/lemmy](https://github.com/dessalines/lemmy) and [yerbamate.dev/dessalines/lemmy](https://yerbamate.dev/dessalines/lemmy), the [Matrix channel](https://matrix.to/#/!BZVTUuEiNmRcbFeLeI:matrix.org?via=matrix.org&via=privacytools.io&via=permaweb.io); and all instances under lemmy.ml. For other projects adopting the Rust Code of Conduct, please contact the maintainers of those projects for enforcement. If you wish to use this code of conduct for your own project, consider explicitly mentioning your moderation policy or making a copy with your own moderation policy so as to avoid confusion.
Adapted from the [Rust Code of Conduct](https://www.rust-lang.org/policies/code-of-conduct), which is based on the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling) as well as the [Contributor Covenant v1.3.0](https://www.contributor-covenant.org/version/1/3/0/).

## About
![main screen](https://i.imgur.com/kZSRcRu.png)|![chat screen](https://i.imgur.com/4XghNh6.png)
[Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).

### Kubernetes
You'll need to have an existing Kubernetes cluster and [storage class](https://kubernetes.io/docs/concepts/storage/storage-classes/).
Setting this up will vary depending on your provider.
To try it locally, you can use [MicroK8s](https://microk8s.io/) or [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/).
Once you have a working cluster, edit the environment variables and volume sizes in `docker/k8s/*.yml`.
You may also want to change the service types to use `LoadBalancer`s depending on where you're running your cluster (add `type: LoadBalancer` to `ports)`, or `NodePort`s.
By default they will use `ClusterIP`s, which will allow access only within the cluster. See the [docs](https://kubernetes.io/docs/concepts/services-networking/service/) for more on networking in Kubernetes.
**Important** Running a database in Kubernetes will work, but is generally not recommended.
If you're deploying on any of the common cloud providers, you should consider using their managed database service instead (RDS, Cloud SQL, Azure Databse, etc.).
Now you can deploy:
```bash
# Add `-n foo` if you want to deploy into a specific namespace `foo`;
# otherwise your resources will be created in the `default` namespace.
kubectl apply -f docker/k8s/db.yml
kubectl apply -f docker/k8s/pictshare.yml
kubectl apply -f docker/k8s/lemmy.yml
```
If you used a `LoadBalancer`, you should see it in your cloud provider's console.
## Develop

# Lemmy v0.6.0 Release (2020-01-16)
`v0.6.0` is here, and we've closed [41 issues!](https://github.com/dessalines/lemmy/milestone/15?closed=1)
This is the biggest release by far:
- Avatars!
- Optional Email notifications for username mentions, post and comment replies.
- Ability to change your password and email address.
- Can set a custom language.
- Lemmy-wide settings to disable downvotes, and close registration.
- A better documentation system, hosted in lemmy itself.
- [Huge DB performance gains](https://github.com/dessalines/lemmy/issues/411) (everthing down to < `30ms`) by using materialized views.
- Fixed major issue with similar post URL and title searching.
- Upgraded to Actix `2.0`
- Faster comment / post voting.
- Better small screen support.
- Lots of bug fixes, refactoring of back end code.
Another major announcement is that Lemmy now has another lead developer besides me, [@felix@radical.town](https://radical.town/@felix). Theyve created a better documentation system, implemented RSS feeds, simplified docker and project configs, upgraded actix, working on federation, a whole lot else.

# Lemmy WebSocket API
*Note: this may lag behind the actual API endpoints [here](../server/src/api).*
## Data types
- `i16`, `i32` and `i64` are respectively [16-bit](https://en.wikipedia.org/wiki/16-bit), [32-bit](https://en.wikipedia.org/wiki/32-bit) and [64-bit](https://en.wikipedia.org/wiki/64-bit_computing) integers.
- <code>Option<***SomeType***></code> designates an option which may be omitted in requests and not be present in responses. It will be of type ***SomeType***.
- <code>Vec<***SomeType***></code> is a list which contains objects of type ***SomeType***.
- `chrono::NaiveDateTime` is a timestamp string in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format. Timestamps will be UTC.
- Other data types are listed [here](../server/src/db).
## Basic usage
Request and response strings are in [JSON format](https://www.json.org).
### Endpoint
Connect to <code>ws://***host***/api/v1/ws</code> to get started.
If the ***`host`*** supports secure connections, you can use <code>wss://***host***/api/v1/ws</code>.
### Testing with [Websocat](https://github.com/vi/websocat)
`websocat ws://127.0.0.1:8536/api/v1/ws -nt`
A simple test command:
`{"op": "ListCategories"}`
### Testing with the [WebSocket JavaScript API](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)
```javascript
var ws = new WebSocket("ws://" + host + "/api/v1/ws");
ws.onopen = function () {
console.log("Connection succeed!");
ws.send(JSON.stringify({
op: "ListCategories"
}));
};
```
## Rate limits
- 1 per hour for signups and community creation.
- 1 per 10 minutes for post creation.
- 30 actions per minute for post voting and comment creation.
- Everything else is not rate-limited.
## Errors
```rust
{
op: String,
message: String,
}
```
## API documentation
### Sort Types
These go wherever there is a `sort` field. The available sort types are:
- `Hot` - the hottest posts/communities, depending on votes, views, comments and publish date
- `New` - the newest posts/communities
- `TopDay` - the most upvoted posts/communities of the current day.
- `TopWeek` - the most upvoted posts/communities of the current week.
- `TopMonth` - the most upvoted posts/communities of the current month.
- `TopYear` - the most upvoted posts/communities of the current year.
- `TopAll` - the most upvoted posts/communities on the current instance.

# Lemmy - A link aggregator / reddit clone for the fediverse.
[Lemmy Dev instance](https://dev.lemmy.ml) *for testing purposes only*
[Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).
For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.
The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling.
Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.
### Why's it called Lemmy?
- Lead singer from [Motörhead](https://invidio.us/watch?v=pWB5JZRGl0U).
- The old school [video game](<https://en.wikipedia.org/wiki/Lemmings_(video_game)>).
- The [Koopa from Super Mario](https://www.mariowiki.com/Lemmy_Koopa).
- The [furry rodents](http://sunchild.fpwc.org/lemming-the-little-giant-of-the-north/).
Made with [Rust](https://www.rust-lang.org), [Actix](https://actix.rs/), [Inferno](https://infernojs.org), [Typescript](https://www.typescriptlang.org/) and [Diesel](http://diesel.rs/).

The configuration is based on the file [defaults.hjson](server/config/defaults.hjson). This file also contains documentation for all the available options. To override the defaults, you can copy the options you want to change into your local `config.hjson` file.
Additionally, you can override any config files with environment variables. These have the same name as the config options, and are prefixed with `LEMMY_`. For example, you can override the `database.password` with
`LEMMY__DATABASE__POOL_SIZE=10`.
An additional option `LEMMY_DATABASE_URL` is available, which can be used with a PostgreSQL connection string like `postgres://lemmy:password@lemmy_db:5432/lemmy`, passing all connection details at once.

First, you need to [install Ansible on your local computer](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html) (e.g. using `sudo apt install ansible`) or the equivalent for you platform.
Then run the following commands on your local computer:
```bash
git clone https://github.com/dessalines/lemmy.git
cd lemmy/ansible/
cp inventory.example inventory
nano inventory # enter your server, domain, contact email
ansible-playbook lemmy.yml --become

Make sure you have both docker and docker-compose(>=`1.24.0`) installed:
```bash
mkdir lemmy/
cd lemmy/
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/lemmy.hjson
# Edit lemmy.hjson to do more configuration
docker-compose up -d
```
and go to http://localhost:8536.
[A sample nginx config](/ansible/templates/nginx.conf), could be setup with:
```bash
wget https://raw.githubusercontent.com/dessalines/lemmy/master/ansible/templates/nginx.conf
# Replace the {{ vars }}
sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf

You'll need to have an existing Kubernetes cluster and [storage class](https://kubernetes.io/docs/concepts/storage/storage-classes/).
Setting this up will vary depending on your provider.
To try it locally, you can use [MicroK8s](https://microk8s.io/) or [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/).
Once you have a working cluster, edit the environment variables and volume sizes in `docker/k8s/*.yml`.
You may also want to change the service types to use `LoadBalancer`s depending on where you're running your cluster (add `type: LoadBalancer` to `ports)`, or `NodePort`s.
By default they will use `ClusterIP`s, which will allow access only within the cluster. See the [docs](https://kubernetes.io/docs/concepts/services-networking/service/) for more on networking in Kubernetes.
**Important** Running a database in Kubernetes will work, but is generally not recommended.
If you're deploying on any of the common cloud providers, you should consider using their managed database service instead (RDS, Cloud SQL, Azure Databse, etc.).
Now you can deploy:
```bash
# Add `-n foo` if you want to deploy into a specific namespace `foo`;
# otherwise your resources will be created in the `default` namespace.
kubectl apply -f docker/k8s/db.yml
kubectl apply -f docker/k8s/pictshare.yml
kubectl apply -f docker/k8s/lemmy.yml
```
If you used a `LoadBalancer`, you should see it in your cloud provider's console.

# Contributing
Information about contributing to Lemmy, whether it is translating, testing, designing or programming.
## Translating
Go [here](https://github.com/dessalines/lemmy#translations) for translation instructions.
## Architecture
### Front end
- The front end is written in `typescript`, using a react-like framework called [inferno](https://infernojs.org/). All UI elements are reusable `.tsx` components.
- The main page and routing are in `ui/src/index.tsx`.
- The components are located in `ui/src/components`.
### Back end
- The back end is written in `rust`, using `diesel`, and `actix`.
- The server source code is split into main sections in `server/src`. These include:
- `db` - The low level database actions.
- Database additions are done using diesel migrations. Run `diesel migration generate xxxxx` to add new things.
- `api` - The high level user interactions (things like `CreateComment`)
- `routes` - The server endpoints .
- `apub` - The activitypub conversions.
- `websocket` - Creates the websocket server.
## Linting / Formatting
- Every front and back end commit is automatically formatted then linted using `husky`, and `lint-staged`.
- Rust with `cargo fmt` and `cargo clippy`.
- Typescript with `prettier` and `eslint`.
