105 Forums & Mailing Lists
\r
106 ----------------------
\r
108 If you can't find what you need in these docs, try consulting the
\r
109 Discourse forums. There are also commit mailing lists for all commits to the LLVM Project.
\r
110 The :doc:`CodeOfConduct` applies to all these forums and mailing lists.
\r
113 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.
\r
115 .. __: https://discourse.llvm.org/
\r
117 `Commits Archive (llvm-commits)`__
\r
118 This list contains all commit messages that are made when LLVM developers
\r
119 commit code changes to the repository. It also serves as a forum for
\r
120 patch review (i.e. send patches here). It is useful for those who want to
\r
121 stay on the bleeding edge of LLVM development. This list is very high
\r
124 .. __: http://lists.llvm.org/pipermail/llvm-commits/
\r
126 `Bugs & Patches Archive (llvm-bugs)`__
\r
127 This list gets emailed every time a bug is opened and closed. It is
\r
128 higher volume than the LLVM-dev list.
\r
130 .. __: http://lists.llvm.org/pipermail/llvm-bugs/
\r
132 `LLVM Announcements`__
\r
133 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.
\r
135 .. __: https://discourse.llvm.org/c/announce/46
\r
137 .. _online-sync-ups:
\r
142 A number of regular calls are organized on specific topics. It should be
\r
143 expected that the range of topics will change over time. At the time of

\r
145 The :doc:`CodeOfConduct` applies to all online sync-ups.
\r
147 If you'd like to organize a new sync-up, please add the info in the table
\r
148 below. Please also create a calendar event for it and invite calendar@llvm.org
\r
149 to the event, so that it'll show up on the :ref:`llvm-community-calendar`.
\r
150 Please see :ref:`llvm-community-calendar-host-guidance` for more guidance on
\r
151 what to add to your calendar invite.

311 Guidance for office hours hosts
\r
312 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
\r
314 * If you're interested in becoming an office hours host, please add your
\r
315 information to the list above. Please create a calendar event for it and
\r
316 invite calendar@llvm.org to the event so that it'll show up on the
\r
317 :ref:`llvm-community-calendar`.
\r
318 Please see :ref:`llvm-community-calendar-host-guidance` for more guidance on
\r
319 what to add to your calendar invite.
\r
320 * When starting an office hours session, consider typing something like "*Hi,
\r
321 I'm available for chats in the next half hour at* video chat URL. *I'm
\r
322 looking forward to having conversations on the video chat or here.*" on the
\r
323 LLVM chat channels that you are already on. These could include:
\r
325 * the `#office-hours Discord channel
\r
326 <https://discord.com/channels/636084430946959380/976196303681896538>`__.
\r
329 Doing this can help:
\r
330 * overcome potential anxiety to call in for a first time,
\r
331 * people who prefer to first exchange a few messages through text chat
\r
332 before dialing in, and
\r
333 * remind the wider community that office hours do exist.
\r
334 * If you decide to no longer host office hours, please do remove your entry
\r
335 from the list above.
\r
343 Users and developers of the LLVM project (including subprojects such as Clang)
\r
344 can be found in #llvm on `irc.oftc.net <irc://irc.oftc.net/llvm>`_.
\r
346 This channel has several bots.
\r
348 * Buildbot reporters
\r
350 * llvmbb - Bot for the main LLVM buildbot master.

\r
435 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
\r
437 Please put the following pieces of information in your calendar invite:
