========= 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 online team meetings. This project allows to define 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 | -o ICALFILE) [-t INDEX_TEMPLATE] [-w INDEX_OUTPUT] [-n CALNAME] [-d CALDESCRIPTION] [-f] A tool that automates the process for testing, integrating, and publishing changes to online meeting schedules. 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 output directory (one file per meeting) -o ICALFILE, --output ICALFILE output file (one file for all meetings) -t INDEX_TEMPLATE, --indextemplate INDEX_TEMPLATE generate an index from selected meetings -w INDEX_OUTPUT, --indexoutput INDEX_OUTPUT output index file -n CALNAME, --name CALNAME name of calendar to set within the ical -d CALDESCRIPTION, --description CALDESCRIPTION description of calendar to set within the ical -f, --force remove/overwrite previous output files 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 BEGIN:VCALENDAR VERSION:2.0 PRODID:-//yaml2ical agendas//EN BEGIN:VEVENT SUMMARY:Barbican Meeting (openstack-meeting-alt) DTSTART;VALUE=DATE-TIME:20141006T200000Z DURATION:PT1H DESCRIPTION:Project: Barbican Meeting\nChair: jraim\nIRC: openstack-meet ing-alt\nAgenda:'* malini - update on Security Guide documentation\n\n * alee_/atiwari - Crypto plugin changes\n\n * arunkant - Target support in barbican policy enforcement\n\n * jaraim - Support for debug mode start i n barbican\, can be merged?\n\n '\n\nDescription: The Barbican project t eam holds a weekly team meeting in\n#openstack-meeting-alt:\n* Weekly on M ondays at 2000 UTC\n* The blueprints that are used as a basis for the Barb ican project can be\n found at https://blueprints.launchpad.net/barbican\ n* Notes for previous meetings can be found here.\n* Chair (to contact for more information): jraim (#openstack-barbican @\n Freenode)\n RRULE:FREQ=WEEKLY END:VEVENT END:VCALENDAR YAML Meeting File ================= Each meeting consists of: * ``project``: the name of the project [MANDATORY] * ``schedule``: a list of schedule each consisting of * ``time``: time string in UTC [MANDATORY] * ``duration``: duration of the meeting in minutes; defaults to 60 * ``start_date``: the date the first meeting takes place on or after. Format `YYYYMMDD`, all values must be zero-padded. * ``day``: the day of week the meeting takes place [MANDATORY] * ``irc``: the irc room in which the meeting is held [MANDATORY] * ``frequency``: frequent occurrence of the meeting [MANDATORY] * ``skip_dates``: A set of dates that the meeting **DOES NOT** happen on * ``skip_date``: Skip the meeting for specified date. Format as ``start_date`` * ``reason``: A comment for why the meeting was skipped * ``chair``: name of the meeting's chair [MANDATORY] * ``description``: a paragraph description about the meeting [MANDATORY] * ``agenda_url``: a link to the agenda page for the meeting * ``project_url``: a link to the project home page for 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. Frequencies ----------- yaml2ical supports a number of possible frequency options: * Event occurs every week: * ``weekly``: Event occurs every week. * Event alternates and starts on the next ``day``: * ``biweekly-even``: Occurs on even weeks (``ISOweek % 2 == 0``) * ``biweekly-odd`` Occurs on odd weeks (``ISOweek % 2 == 1``): * Event occurs every 4 weeks and starts on the next ``day``: * ``quadweekly``: Occurs when ``ISOweek % 4 == 0`` * ``quadweekly-week-1``: Occurs when ``ISOweek % 4 == 1`` * ``quadweekly-week-2``, ``quadweekly-alternate``: Occurs when ``ISOweek % 4 == 2`` * ``quadweekly-week-3``: Occurs when ``ISOweek % 4 == 3`` * Event occurs in a particular week of a month: * ``first-monday``: On the first Monday of the month. * ``second-tuesday``: On the second Tuesday of the month. * ``third-wednesday``: On the third Wednesday of the month. * ``fourth-thursday``: On the fourth Thursday of the month. * etc * Event doesn't happen on a defined schedule but is used as a placeholder for html generation: * ``adhoc`` .. note:: Odd/Even and week numbers are based on the ISO week number. ISO weeks can be checked with ``%V`` in `GNU date(1)`_ .. _`GNU date(1)`: https://www.gnu.org/software/coreutils/manual/html_node/date-invocation.html .. note:: All alternating meetings suffer from a probelm when years include an ISO week 53, this happened in 2015/2016 and happens approximately every 5 years. Example 1 --------- 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. See above for notes on `frequency`. `adhoc` can be used to list the possibility of something in the schedule but will not actually generate any calendar events. This can be used for placeholders and will act as a noop when generating the calendar. :: 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``. :: agenda_url: https://wiki.openstack.org/wiki/Meetings/Nova * An extra property containing the project URL is saved in ``project_url`` and can be accessed in the template file as ``meeting.extras.project_url``. :: project_url: https://wiki.openstack.org/wiki/Nova * An extra property containing the MeetBot #startmeeting ID for the project is saved in ``meeting_id`` and can be accessed in the template file as ``meeting.extras.meeting_id``. :: meeting_id: nova Example 2 --------- The following shows a complete YAML file for the IRC meetings for "example project". The project starts holding weekly meetings from October 1st, the project team has a "face to face" meeting on the 26th of October so that IRC meeting should be ommited from the ical schedule * This YAML :: project: Example Project Meeting project_url: https://wiki.openstack.org/wiki/Example agenda_url: https://wiki.openstack.org/wiki/Meetings/Example meeting_id: example chair: A.
