Export google calendar to org-mode
Overview
A simple little CLI tool to export your google calendar into org-mode.
Unlike the synchronization workflow described on the on the Worg website, gcal-to-org uses Google's API Client Library for Java. Since it authenticates using OAUTH, there is no need to make your calendar publicly available through a "hidden" url.
This tool is in the early stages and narrowly focused on my particular needs. However, it should be easy to adapt it to your use-case, and I would be happy to iterate on the design.
Installation
npm install -g gcal-to-org
Usage
First create a config.edn
config file somwhere. Below is a minimal example for a single
calendar. See config.example.edn for a fully commented example.
Then run just run the CLI tool to print org-mode text to stdout.
gcal-to-org path/to/config.edn
On the first run, it will open an OAUTH window in your default browser and cache your OAUTH tokens to disk. On subsequent runs, it simply uses the cached credentials and behaves like any other CLI tool.
Obtaining Google API credentials
You need to register gcal-to-org as an application yourself to obtain a Client ID and Client secret.
Go to the Google API Manager and create a new project under any name.
Within that project, enable the "Calendar" API. There should be a searchbox where you can just enter those terms.
In the sidebar, select "Credentials" and then create a new "OAuth Client ID". The application type is "Other".
You’ll be prompted to create a OAuth consent screen first. Fill out that form however you like.
Finally you should have a Client ID and a Client secret. Provide these in the config below.
Emacs integration
Everyone's setup is different, but in case you are interested, here is how I call the tool from emacs.
;;; Write work agenda here(defvar my-work-agenda-file "~/var/work.org") ;;; Add work agenda to default agenda files(add-to-list 'org-agenda-files my-work-agenda-file) (defun my-update-work-agenda-file () "Create work agenda file by pulling from Google Calendar." (if (zerop (call-process "gcal-to-org" nil `(:file ,my-work-agenda-file) nil "/path/to/config.edn")) (let ((buf (find-buffer-visiting my-work-agenda-file))) ;; Revert work buffer if it exists (when buf (with-current-buffer buf (revert-buffer nil t))) (message "Successfully updated %s" my-work-agenda-file)) (message "Failed to update %s" my-work-agenda-file))) ;;; Add command to call gcal-to-org from the agenda dispatch view. Bound to "w" key.(add-to-list 'org-agenda-custom-commands '("w" "Update work agenda file" ;; This functions gets called with a match object that we discard. (lambda (_) (my-update-work-agenda-file))) t)
