96Forums & Mailing Lists
97----------------------
98
99If you can't find what you need in these docs, try consulting the
100Discourse forums. There are also commit mailing lists for all commits to the LLVM Project.
101The :doc:`CodeOfConduct` applies to all these forums and mailing lists.
102
103`LLVM Discourse`__
104  The forums for all things LLVM and related sub-projects. There are categories and subcategories for a wide variety of areas within LLVM. You can also view tags or search for a specific topic.
105
106  .. __: https://discourse.llvm.org/
107
108`Commits Archive (llvm-commits)`__
109  This list contains all commit messages that are made when LLVM developers
110  commit code changes to the repository. It also serves as a forum for
111  patch review (i.e. send patches here). It is useful for those who want to
112  stay on the bleeding edge of LLVM development. This list is very high
113  volume.
114
115  .. __: http://lists.llvm.org/pipermail/llvm-commits/
116
117`Bugs & Patches Archive (llvm-bugs)`__
118  This list gets emailed every time a bug is opened and closed. It is
119  higher volume than the LLVM-dev list.
120
121  .. __: http://lists.llvm.org/pipermail/llvm-bugs/
122
123`LLVM Announcements`__
124  If you just want project wide announcements such as releases, developers meetings, or blog posts, then you should check out the Announcement category on LLVM Discourse.

130Online Sync-Ups
131---------------
132
133A number of regular calls are organized on specific topics. It should be
134expected that the range of topics will change over time. At the time of
135writing, the following sync-ups are organized.
136The :doc:`CodeOfConduct` applies to all online sync-ups.
137
138If you'd like to organize a new sync-up, please add the info in the table
139below. Please also create a calendar event for it and invite calendar@llvm.org
140to the event, so that it'll show up on the :ref:`llvm-community-calendar`.
141Please see :ref:`llvm-community-calendar-host-guidance` for more guidance on
142what to add to your calendar invite.

363For event owners, our Discord bot also supports sending automated announcements
364of upcoming office hours. Please see the :ref:`discord-bot-event-pings` section
365for info.

367Guidance for office hours hosts
368^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
369
370* If you're interested in becoming an office hours host, please add your
371  information to the list above. Please create a calendar event for it and
372  invite calendar@llvm.org to the event so that it'll show up on the
373  :ref:`llvm-community-calendar`.
374  Please see :ref:`llvm-community-calendar-host-guidance` for more guidance on
375  what to add to your calendar invite.
376* When starting an office hours session, if you haven't set up the Discord bot
377  integration, consider typing something like "*Hi, I'm available for chats in
378  the next half hour at* video chat URL. *I'm looking forward to having
379  conversations on the video chat or here.*" on the
380  `#office-hours Discord channel <https://discord.com/channels/636084430946959380/976196303681896538>`__.
381
382  Doing this can help:
383    * overcome potential anxiety to call in for a first time,
384    * people who prefer to first exchange a few messages through text chat
385      before dialing in, and
386    * remind the wider community that office hours do exist.
387* If you decide to no longer host office hours, please do remove your entry
388  from the list above.

392-------
393
394Users and developers of the LLVM project (including subprojects such as Clang)
395can be found on the community's `Discord <https://discord.com/channels/636084430946959380/636725486533345280>`_
396chat server. The server is actively moderated.
397
398The #buildbot-status channel has a bot for
399`LLVM buildbot <http://lab.llvm.org/buildbot/#/console>`_ status changes. The
400bot will update the channel with a link to a build bot when a build goes from
401passing to failing and again when the build goes from failing back to passing.
402It is a great way to actively monitor the status of the build.
403
404The bot also supports @mention-ing you when your email appears on a blamelist.
405For more details, DM ``help`` to the bot.

409Discord bot event pings
410^^^^^^^^^^^^^^^^^^^^^^^
411
412Our Discord bot supports automatically sending messages about upcoming events
413on `the LLVM community calendar <https://calendar.google.com/calendar/u/0/embed?src=calendar@llvm.org>`_
414to Discord. This behavior is controlled on a per-event basis, by metadata in the
415event's description. Each piece of metadata should be on its own line in the
416event description.
417
418The currently supported metadata is:
419
420- ``discord-bot-event-type`` - **Required**. Specifies the event type. Valid
421  values are ``office-hours`` and ``sync-up``.
422- ``discord-bot-channels-to-mention`` - **Sometimes required**. A
423  comma-separated list of Discord channels to post notifications in. If your
424  ``discord-bot-event-type`` is ``office-hours``, the ``#office-hours`` channel
425  will be implicitly appended to this list (ergo, you don't need to specify this
426  item). Otherwise, you must specify a value here.
427- ``discord-bot-mention`` - **Optional**. A comma-separated list of people to
428  ping on each event notification. All names mentioned must be Discord
429  usernames, and must have a leading ``@``. e.g., ``@foo, @bar``.
430- ``discord-bot-reminder-time-before-start`` - **Optional**. The number of
431  minutes before the beginning of an event to send a ping. This should be
432  formatted as an integer. Defaults to 30.
433- ``discord-bot-message`` - **Optional**. Text to append to all event pings.
434
435An example of an event description with valid metadata is::
436
437  Regular office hours to chat with people about LLVM! We can help with
438  questions, troubleshooting bugs, etc.
439
440  discord-bot-channels-to-mention: #beginners, #foo
441  discord-bot-event-type: office-hours
442  discord-bot-mention: @gburgessiv, @bar
443  discord-bot-message: Come join us for office hours!
444  discord-bot-reminder-time-before-start: 5
445
446This metadata will prompt the Discord bot to:
447
448* send pings 5 minutes before the given event starts, mentioning ``@gburgessiv``
449  and ``@bar`` in the ping
450* send the pings to the ``#beginners``, ``#foo``, and ``#office-hours`` channels
451* include the text "Come join us for office hours!" in the ping
452
453A few minutes before sending a ping, the bot will double-check that the event
454hasn't been cancelled.
455
456If you need help troubleshooting, or have feature requests/questions, please
457feel free to ping @gburgessiv!

513We aim to maintain a public calendar view of all events happening in the LLVM
514community such as :ref:`online-sync-ups` and :ref:`office-hours`. The calendar
515can be found at
516https://calendar.google.com/calendar/u/0/embed?src=calendar@llvm.org and can
517also be seen inline below:

530Guidance on what to put into LLVM community calendar invites
531^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
532
533To add your event, create a calendar event for it and invite calendar@llvm.org
534on it. Your event should then show up on the community calendar.
535
536Please put the following pieces of information in your calendar invite:
537
538* Write a single paragraph describing what the event is about. Include things
539  such as who the event is for and what sort of topics are discussed.
540* State explicitly that the :doc:`CodeOfConduct` applies to this event.
541* Make it clear who:
542
543  * the organizer is.
544
545  * the person to contact is in case of any code-of-conduct issues.  Typically,
546    this would be the organizer.
547
548* If you have meeting minutes for your event, add a pointer to where those live.
549  A good place for meeting minutes could be as a post on LLVM Discourse.
550
551* If you're hosting a sync-up or office hours event and would like it to be
552  announced by the Discord bot, add the relevant metadata (full descriptions
553  available in the :ref:`discord-bot-event-pings` section).
554

559  This event is a meetup for all developers of LLDB. Meeting agendas are posted
560  on discourse before the event.
561
562  Attendees are required to adhere to the LLVM Code of Conduct
563  (https://llvm.org/docs/CodeOfConduct.html). For any Code of Conduct reports,
