# Features
## Github
- Login with OAuth2.
- Ability to create Github issues on any project.
- Ability to track updates (add webhooks) to projects. This includes new issues, pull requests as well as commits.
- Ability to expand issues when mentioned as `foo/bar#1234`.
- Ability to assign a "default repository" for a Matrix room to allow `#1234` to automatically expand, as well as shorter issue creation command syntax.
## JIRA
- Login with OAuth1.
- Ability to create JIRA issues on a project.
- Ability to expand JIRA issues when mentioned as `FOO-1234`.
## Giphy
- Ability to query Giphy's "text-to-gif" engine.
# Installing
Go-NEB is built using Go 1.5+ and [GB](https://getgb.io/). Once you have installed Go, run the following commands:
```bash
# Install gb
go get github.com/constabulary/gb/...
# Clone the go-neb repository
git clone https://github.com/matrix-org/go-neb
cd go-neb
# Build go-neb
gb build github.com/matrix-org/go-neb
```
# Running
Go-NEB uses environment variables to configure its SQLite database and bind address. To run Go-NEB, run the following command:
```bash
BIND_ADDRESS=:4050 DATABASE_TYPE=sqlite3 DATABASE_URL=go-neb.db BASE_URL=https://public.facing.endpoint bin/go-neb
```
- `BIND_ADDRESS` is the port to listen on.
- `DATABASE_TYPE` MUST be "sqlite3". No other type is supported.
- `DATABASE_URL` is where to find the database file. One will be created if it does not exist.
- `BASE_URL` should be the public-facing endpoint that sites like Github can send webhooks to.
Go-NEB needs to be "configured" with clients and services before it will do anything useful.
## Configuring clients
Go-NEB needs to connect as a matrix user to receive messages. Go-NEB can listen for messages as multiple matrix users. The users are configured using an HTTP API and the config is stored in the database. To create a user:
```bash
curl -X POST localhost:4050/admin/configureClient --data-binary '{
"UserID": "@goneb:localhost:8448",
"HomeserverURL": "http://localhost:8008",
"AccessToken": "<access_token>",
"Sync": true,
"AutoJoinRooms": true,
"DisplayName": "My Bot"
}'
```
- `UserID` is the complete user ID of the client to connect as. The user MUST already exist.
- `HomeserverURL` is the complete Homeserver URL for the given user ID.
- `AccessToken` is the user's access token.
- `Sync`, if `true`, will start a `/sync` stream so this client will receive incoming messages. This is required for services which need a live stream to the server (e.g. to respond to `!commands` and expand issues). It is not required for services which do not respond to Matrix users (e.g. webhook notifications).
- `AutoJoinRooms`, if `true`, will automatically join rooms when an invite is received. This option is only valid when `Sync: true`.
- `DisplayName`, if set, will set the given user's profile display name to the string given.
Go-NEB will respond with the previous configuration for this client, if one exists, as well as echo back the complete configuration for the client:
```json
{
"OldClient": {},
"NewClient": {
"UserID": "@goneb:localhost:8448",
"HomeserverURL": "http://localhost:8008",
"AccessToken": "<access_token>",
"Sync": true,
"AutoJoinRooms": true,
"DisplayName": "My Bot"
}
}
```
