Fill Google Calendars with events taken from a Google Spreadsheet.

pip install haunts

To use Google Calendar and Google Spreasheet APIs you must generate a Google API application and download a credentials.json:

• Run haunts --config. It will create the ~/.haunts folder and an haunts.ini file inside it.
• Edit the haunts.ini file by setting the CONTROLLER_SHEET_DOCUMENT_ID
• Go to https://console.cloud.google.com/home/dashboard and create a Project called haunts.
  • In the search bar, search Credentials APIs and services and enable it.
  • Click on Create Credentials, set Desktop as the type and save the json file as ~/.haunts/credentials.json.
  • In the search bar, search Google Sheets API and Google Calendar API and activate them.
• Run haunts normally. It will ask you to authenticate to both the Google Sheets and the Google Calendar APIs (a browser should be automatically opened for you). This action will create the following files: ~/.haunts/calendars-token.json and ~/.haunts/sheets-token.json

Command line help is accessible using:

haunts --help

Usage

haunts <SHEET_NAME>

You can limits events interaction to a single day, or a set of days by using the -d parameter (can be used multiple times):

haunts --day=2021-07-08 <SHEET_NAME>

The command will try to access a Google Spreatsheet you must own (write access required), specifically it will read a single sheet at time inside the spreadsheet.

The referenced sheet must contains a set of columns. Headers names are important but orders matters not. Any additional columns will be ignored.

An example sheet is provided.

The partition in multiple sheets is designed to keep every month in a separate sheet, but this is not strictly checked.

Every sheet should contains following headers:

Date

(date)

The day where the event will be created

Start time

(time string in format HH:MM or empty) - optional column

If provided, the current event will start at given time. This will influence also events defined after this row

Spent

(number or empty)

How long the event will last. Leave empty to create a full-day event

Project

(string)

Project name as it's named in the config sheet (see below)

Activity

(string)

Summary of the event

Details

(string, optional)

Additional text for the event description

Event id

(string)

Leave this empty. It will be filled with the id of the generated event

Link

(text)

Leave this empty. It will be filled with a link to the event inside Google Calendar

Action

(char)

See below. If empty: it will be filled with an I when an event is created

The spreadsheet must also contains a configuration sheet (default name is config, can be changed in the .ini) where you must put two columns (with headers):

id

The id of a Google Calendar associated to this project. You must have write access to this calendar.

name

The name of the project, like an alias to the calendar

A project name can be associated to the same calendar id multiple times.

Values in the name column are the only valid values for the Project column introduced above

Let says you run something like this:

haunts --day=2021-07-08 July

haunts will access the sheet named July in the spreadsheet configured in the .ini file. Only rows where the Date filed will match the --day parameter will be considered (if this param is not provided: the full sheet content is analyzed).

For every rows that match, haunts will:

• Generate a new event, starting from a default time (this can be configured in the .ini). The event will last for Spent hours
• The next event will start where the previous ended
• If the event will be successfully created, an "I" will be placed in the Action column. This will make future executions to ignore the line.
• Other columns will be read or filled as described above.

Possible values you can find (or put yourself) in the Action column:

• I

  Ignore: execution will just ignore this line

• D

  Delete: execution will clear Action, Event id and Link cells for this row, and delete the related calendar event. So: next execution will likely fill this line again (this is a poor-man-edit)

• Rows in the sheet must be sorted ascending
• haunts will not check for already filled time slots (yet?), so overlapping of events may happens

In B-Open this is how we register our worklogs, participation to projects in multiple Google Calendars.

An haunt is a monster from Dungeons&Dragons, which was translated to italian as "Presenza".

But "presenza" is the same term used in italian for "participation", so how we call our worklogs.

And filling worklogs haunt us.
