Printable Calendar

Generate printable agendas from Google Calendars.

I got sick of Google Calendar's terrible print dialog and decided to code around it. This command line utility will download a day, week, work week, or month of agenda items and render them in your default browser so you can print them easily.

Installation and Setup

gem install printable_calendar

0. Copy the sample-config.json file.
1. You need a Google OAuth client ID and secret. You get those here. First, you have to create a project, then add some OAuth credentials (cselect "OAuth client ID" under the "Create credentials" dropdown). Make sure you add the Calendar API to the project. Put the client ID and secret into the json file (You may also stash them in env vars: PRINTABLE_CALENDAR_CLIENT_ID and PRINTABLE_CALENDAR_CLIENT_SECRET. Just remove the keys from your JSON file if you do.)
2. You need a refresh token. Having saved your partially filled out JSON file, run printable_calendar -g. That will open a dialog asking you to accept that your app can have access to your data. Just follow the instructions in the terminal. Paste that refresh token into the JSON file. (You can also use an env var for this: PRINTABLE_CALENDAR_REFRESH_TOKEN).
3. Finally you need the calendars you want to pull in info from; grab their IDs through the Google Calendar UI by finding them in the left sidebar, clicking the little down arrow, clicking "settings", and then copying the email-looking thing next to "Calendar ID".

Usage

Run printable_calendar -c your-config-file.json. The application will download your events, create an HTML file in your temp dir, and open it in your default browser. All you have to do is print it.

There are a few other options. They're available in both the JSON file and as command line switches. Here are all them:
