# PR Labeler
A GitHub App built with [Probot](https://github.com/probot/probot) that enables
a GitHub bot to label PRs automatically based on title and body against a list
of defined labels.
## Config
Add a `pr-labeler.yml` configuration file to your repository's `.github`
directory with the following content:
```yaml
# .github/pr-labeler.yml
# The bot always updates the labels, add/remove as necessary [default: false]
alwaysReplace: false
# Treats the text and labels as case sensitive [default: true]
caseSensitive: true
# Array of labels to be applied to the PR [default: []]
customLabels:
# Finds the `text` within the PR title and body and applies the `label`
- text: '#bug'
label: 'bug'
- text: '#test'
label: 'test'
- text: '#feature'
label: 'feature'
# Search the body of the PR for the `text` [default: true]
searchBody: true
# Search the title of the PR for the `text` [default: true]
searchTitle: true
# Search for whole words only [default: false]
wholeWords: false
```
## Development
If you want to work on the bot, you can follow the instructions below.
### Setup
```sh
# Install dependencies
pnpm install
# Build the bot (we need to transpile TypeScript into JavaScript)
pnpm build
# Run the bot
pnpm start
```
### Docker
```sh
# 1. Build container
docker build -t pr-labeler .
# 2. Start container
docker run -e APP_ID= -e PRIVATE_KEY= pr-labeler
```
### Deployment
A few environment variables need to be set in order to deploy the bot:
```sh
# The APP_ID and PRIVATE_KEY are required to authenticate the GitHub App
export APP_ID=
export PRIVATE_KEY=
# Alternatively, you can set the PRIVATE_KEY_PATH to the path of the private key
# export PRIVATE_KEY_PATH=
# The WEBHOOK_SECRET is used to verify incoming webhooks from GitHub
export WEBHOOK_SECRET=
```
