# Google Calendar CLI
Command-line interface for Google Calendar operations.
## Installation
```bash
npm install -g @mariozechner/gccli
```
## Setup
### Google Cloud Console (one-time)
1. [Create a new project](https://console.cloud.google.com/projectcreate) (or select existing)
2. [Enable the Google Calendar API](https://console.cloud.google.com/apis/api/calendar-json.googleapis.com)
3. [Set app name](https://console.cloud.google.com/auth/branding) in OAuth branding
4. [Add test users](https://console.cloud.google.com/auth/audience) (all Gmail addresses you want to use)
5. [Create OAuth client](https://console.cloud.google.com/auth/clients):
- Click "Create Client"
- Application type: "Desktop app"
- Download the JSON file
### Configure gccli
First check if already configured:
```bash
gccli accounts list
```
If no accounts, guide the user through setup:
1. Ask if they have a Google Cloud project with Calendar API enabled
2. If not, walk them through the Google Cloud Console steps above
3. Have them download the OAuth credentials JSON
4. Run: `gccli accounts credentials ~/path/to/credentials.json`
5. Run: `gccli accounts add <email>` (use `--manual` for browserless OAuth)
## Usage
Run `gccli --help` for full command reference.
Common operations:
- `gccli <email> calendars` - List all calendars
- `gccli <email> events <calendarId> [--from <dt>] [--to <dt>]` - List events
