yaml2ical

This tool converts a series of meeting descriptions in YAML format into one or several .ics files suitable for calendaring. It checks for scheduling conflicts in specific locations.

Rationale

yaml2ical aims to provide an easier way to manage OpenStack team meetings. Currently, each team's meeting time and agenda are listed at:

https://wiki.openstack.org/wiki/Meetings

This project allows to replace each meeting with well-defined YAML files, which can be code-reviewed, then continuously-integrated into .ics files for general consumption.

Getting Started

Running Locally from Command Line

To test this project locally, you must have the following requirements installed:

• Python 3.3+
• iCalendar python library
• PyYaml python library

Before running this tool, first edit some meeting YAML files in the meetings directory. To create a new meeting YAML file, read the YAML Meeting File section below.

$ pip install yaml2ical
$ yaml2ical
usage: yaml2ical [-h] -y YAML_DIR -i ICAL_DIR [-f]

A tool that automates the process for testing, integrating, and
publishing changes to OpenStack meetings using the existing OpenStack
project infrastructure.

optional arguments:
  -h, --help            show this help message and exit
  -y YAML_DIR, --yamldir YAML_DIR
                        directory containing YAML to process
  -i ICAL_DIR, --icaldir ICAL_DIR
                      directory to store converted iCal
  -f, --force           forcefully remove old .ics files from iCal
  directory

The following are a few scenarios:

Generate .ics files locally from existing yaml meeting files:

$ yaml2ical -y meetings/ -i icals/

The generated .ics files are not tracked in this git repository, but they are available locally to import into your calendar. Note, to remove stale .ics files, use the --force argument:

$ ls icals/
Barbican Meeting-b58d78a4.ics
Ceilometer Team Meeting-9ed7b5b4.ics
Chef Cookbook Meeting-2418b331.ics

With each .ics file looking something similar to:

$ cat icals/Barbican\ Meeting-b58d78a4.ics

YAML Meeting File

Each meeting consists of:

• project: the name of the project
• schedule: a list of schedule each consisting of
  • time: time string in UTC
  • day: the day of week the meeting takes place
  • irc: the irc room in which the meeting is held
  • frequency: frequent occurrence of the meeting
• chair: name of the meeting's chair
• description: a paragraph description about the meeting

The file name should be a lower-cased, hyphenated version of the meeting name, ending with .yaml . For example, Keystone team meeting should be saved under keystone-team-meeting.yaml.

Any other values listed in the YAML file are also available for use in templates, making it easy to build links to agenda pages for the meeting or logs of past meetings. In the template file, use meeting.extras.name to access the value.

Example

This is an example for the yaml meeting for Nova team meeting. The whole file will be import into Python as a dictionary.

• The project name is shown below.

  project:  Nova Team Meeting

• The schedule is a list of dictionaries each consisting of time in UTC, day of the week, the irc meeting room, and the frequency of the meeting. Options for the frequency are weekly, biweekly-even, and biweekly-odd at the moment.

  biweekly-odd are weeks where the ISO week number is an odd value. Correspondingly biweekly-even are weeks where the ISO week number is even. This unfortunately will break down on the transition from 2015 to 2016 as 2015 has 53 ISO weeks (an odd value) and then the first week of 2016 is week 1 (also an odd value).

  schedule:
      - time:       '1400'
        day:        Thursday
        irc:        openstack-meeting-alt
        frequency:  biweekly-even
  
      - time:       '2100'
        day:        Thursday
        irc:        openstack-meeting
        frequency:  biweekly-odd

• The chair is just a one liner.

  chair:  Russell Bryant

• The project description is as follows. Use > for paragraphs where new lines are folded, or | for paragraphs where new lines are preserved.

  description:  >
      This meeting is a weekly gathering of developers working on OpenStack.
      Compute (Nova). We cover topics such as release planning and status,
      bugs, reviews, and other current topics worthy of real-time discussion.

• An extra property containing the agenda for the meeting is saved in agenda_url and can be accessed in the template file as meeting.extras.agenda_url.
