NAME
       public-inbox-config - public-inbox config file description

SYNOPSIS
       ~/.public-inbox/config

DESCRIPTION
       The public-inbox config file is parseable by git-config(1).  This is a
       global configuration file for mapping/discovering all public-inboxes
       used by a particular user.

CONFIGURATION FILE
   EXAMPLE
               [publicinbox "test"]
                       inboxdir = /home/user/path/to/test.git
                       ; multiple addresses are supported
                       address = test@example.com
                       ; address = alternate@example.com
                       url = http://example.com/test
                       newsgroup = inbox.test

                       ; backwards compatibility with public-inbox pre-1.2.0,
                       ; "inboxdir" takes precedence over "mainrepo"
                       mainrepo = /home/user/path/to/test.git

   VARIABLES
       publicinbox.<name>.address
               The email address of the public-inbox.  May be specified more
               than once for merging multiple mailing lists (or migrating to
               new addresses).  This must be specified at least once, the
               first value will be considered the primary address for
               informational purposes.

               Default: none, required

       publicinbox.<name>.inboxdir
               The absolute path to the directory which hosts the public-
               inbox.  This must be specified once.

               This was previously known as "mainrepo", which remains
               supported, but "inboxdir" takes precedence.

               Absolute pathnames longer than 244 bytes cannot be indexed with
               public-inbox-extindex(1)

               Default: none, required

       publicinbox.<name>.url
               The primary URL for hosting the HTTP/HTTPS archives.
               Additional HTTP/HTTPS URLs may be specified via
               "$GIT_DIR/cloneurl" as documented in gitweb(1)

               Default: none, optional

       publicinbox.<name>.newsgroup
               The NNTP group name for use with public-inbox-nntpd(1).  This
               may be any newsgroup name with hierarchies delimited by ".".
               For example, the newsgroup for <mailto:meta@public-inbox.org>
               is: "inbox.comp.mail.public-inbox.meta"

               It also configures the folder hierarchy used by
               public-inbox-imapd(1) as well as public-inbox-pop3d(1)

               Omitting this for a given inbox will prevent the inbox from
               being served by public-inbox-nntpd(1), public-inbox-imapd(1),
               and/or public-inbox-pop3d(1)

               Newsgroup names should be all lowercase and have a maximum
               length of 244 bytes.  Uppercase characters are converted to
               lowercase for compatibility with IMAP, POP3, and our
               public-inbox-extindex(1) and public-inbox-cindex(1) tools
               starting with public-inbox 2.0+ (they were unusable before).

               Default: none, optional

       publicinbox.<name>.watch
               See public-inbox-watch(1)

       publicinbox.<name>.watchheader
               See public-inbox-watch(1)

       publicinbox.<name>.listid
               The rfc2919 <https://tools.ietf.org/html/rfc2919> header
               without angle brackets for public-inbox-mda(1) deliveries and
               public-inbox-watch(1).

               For public-inbox-watch users, this is a shortcut for specifying
               "publicinbox.$NAME.watchheader=List-Id:<foo.example.com>"

               For public-inbox-mda users, this may be used to avoid recipient
               matching via "ORIGINAL_RECIPIENT" environment variable.

               This may be specified multiple times for merging multiple
               mailing lists into a single public-inbox, only one "List-Id"
               header needs to match.

               Default: none

       publicinbox.<name>.imapmirror
               This may be the full IMAP URL of an independently-run IMAP
               mirror.

               Default: none

       publicinbox.<name>.nntpmirror
               This may be the full NNTP URL of an independently-run mirror.
               For example, the https://public-inbox.org/meta/ inbox is
               mirrored by Gmane at
               "nntp://news.gmane.io/gmane.mail.public-inbox.general"

               Default: none

       publicinbox.<name>.indexlevel
               The indexing level for public-inbox-index(1)

               "basic" only requires DBD::SQLite(3pm) and provides all NNTP
               functionality along with thread-awareness in the WWW interface.

               "medium" requires Xapian(3pm) or Search::Xapian(3pm) to provide
               full-text term search functionality in the WWW UI.

               "full" also includes positional information used by Xapian to
               allow for searching for phrases using quoted text.  (e.g.
               "looking for a complete sentence")

               Default: "full"

       publicinbox.<name>.boost
               Control indexing order for public-inbox-extindex(1), with ties
               broken by config file order.  This only affects indexing and
               does not affect messages which are already indexed.

               Default: 0

       publicinbox.<name>.indexSequentialShard
               See "publicInbox.indexSequentialShard" in public-inbox-index(1)

       publicinbox.<name>.httpbackendmax
               If a digit, the maximum number of parallel git-http-backend(1)
               processes to allow for cloning this particular inbox.

               If an alphanumeric value starting with a lowercase alphabetic
               character is specified, the inbox will use a "NAMED LIMITER"
               which can be shared by multiple inboxes.

               Default: 32 (using a default limiter shared by all inboxes)

       publicinbox.<name>.coderepo
               The nickname of a "coderepo" section associated with the inbox.
               May be specified more than once for M:N mapping of code repos
               to inboxes.  If enabled, diff hunk headers in patch emails will
               link to the line numbers of blobs.

               Unnecessary with "--join" in public-inbox-cindex(1)

               Default: none

       publicinbox.<name>.altid
               Index by an alternative ID mechanism as a Xapian search prefix
               e.g.  "gmane:1234".  This is useful to allow looking up legacy
               serial IDs (e.g. gmane article numbers).

               It must be specified in the form of
               "serial:$USER_PREFIX:file=$SQLITE_FILENAME" where $USER_PREFIX
               is a lowercase prefix like "gmane" for search queries, and
               $SQLITE_FILENAME points to an SQLite DB.  $SQLITE_FILENAME may
               be an absolute path or a path relative to "INBOXDIR" for v2
               inboxes or "INBOXDIR/public-inbox" for v1 inboxes.

               The schema of $SQLITE_FILENAME should be the same as for
               "msgmap.sqlite3".  See "scripts/xhdr-num2mid" in the public-
               inbox source tree for an example of how to generate such a
               mapping via NNTP.

               This is a noop with "indexlevel=basic"

               Default: none

       publicinbox.<name>.indexheader
               Supports indexing of arbitrary mail headers in Xapian.

               It must be specified in the form of
               "$TYPE:$USER_PREFIX:$MAIL_HEADER:$PARAMS" where $TYPE
               determines how it's indexed and queried; $USER_PREFIX is a
               lowercase prefix for search queries, $MAIL_HEADER is the header
               to index (e.g. "X-Label"), $PARAMS is a URL-style query string
               for optional parameters.

               Valid $TYPE values (in ascending order of storage cost) are as
               follows:

               * "boolean_term" - index for simple filtering (not sortable by
               relevance)

               * "text" - add frequency information to allow sorting by
               relevance

               * "phrase" - add positional information to match sentences or
               phrases

               In other words: "phrase" forces indexing of a particular header
               to behave like it used "indexlevel=full"; while "text" indexes
               as if that header used "indexlevel=medium".

               Valid keys in $PARAMS include:

               * raw - do not perform RFC2047 decoding of headers

               Example:

                       [publicinbox "foo"]
                               indexheader = boolean_term:xlabel:X-Label:raw=1

               Support for other parameters is not finalized and subject to
               change.

               This is a noop with "indexlevel=basic"

               New in public-inbox 2.0+

               Default: none

       publicinbox.<name>.replyto
               May be used to control how reply instructions in the PSGI
               interface are displayed.

               ":none=dead inbox" may be specified to denote an inactive list
               ("dead inbox" may be replaced with another phrase).

               A list of comma-delimited email addresses may be specified.
               This can be useful for dedicated inboxes for bot emails, but
               discussion happens on a separate mailing list/inbox.

               Mirrors of existing centralized mailing lists may use ":list"
               here to redirect mail only to the configured inbox address.
               The use of ":list" is discouraged for new mailing lists, as it
               leads to centralization.

               Default: :all

       publicinbox.css
               The local path name of a CSS file for the PSGI web interface.
               Space-separated attributes ("key=val" or "key='val with
               spaces'") may be specified after the path on the same line;
               "media", "title" and "href" are currently supported, and match
               the associated attributes of the HTML "<style>" tag.

               "href" may be specified to point to the URL of a remote CSS
               file and the path may be "/dev/null" or any empty file.

               public-inbox 2.0+ also supports a "load" attribute with values
               "link" or "import"; "link" forces the use of a "<link>" tag and
               disables inlining CSS into the "<style>" tag while "import"
               puts CSS @import statements into the "<style>" tag.  "import"
               appears necessary for some browser and "media" query
               combinations.

               Multiple files may be specified and will be included in the
               given order, but files specified via "load=import" are always
               handled first.

               Example:

                       [publicinbox]
                               css = /path/to/216dark.css title=216dark \
                                 media='screen,(prefers-color-scheme:dark)'

               See the contrib/css directory of the public-inbox source
               <https://80x24.org/public-inbox.git/tree/contrib/css> for more
               examples.

       publicinboxImport.dropUniqueUnsubscribe
               Drop "List-Unsubscribe" headers if the message also includes
               the "List-Unsubscribe-Post: List-Unsubscribe=One-Click" header
               to signal MUAs to support an instantaneous unsubscribe.  This
               is strongly recommended for users creating their own public
               archives of mailing lists they subscribe to, otherwise any
               archive reader can unsubscribe the archivist.

               This may break DKIM signatures if the "List-Unsubscribe*"
               headers are signed, but breaking DKIM signatures is the lesser
               evil compared to allowing any reader to unsubscribe the
               archivist.

               This affects public-inbox-mda(1), public-inbox-watch(1), and
               public-inbox-learn(1)

       publicinboxmda.spamcheck
               This may be set to "none" to disable the use of SpamAssassin
               spamc(1) for filtering spam before it is imported into git
               history.  Other spam filtering backends may be supported in the
               future.

               Default: spamc

       publicinboxwatch.spamcheck
               See public-inbox-watch(1)

       publicinboxwatch.watchspam
               See public-inbox-watch(1)

       publicinbox.imapserver
               Set this to point to the hostname(s) of the
               public-inbox-imapd(1) instance.  This is used to advertise the
               existence of the IMAP endpoint in the PublicInbox::WWW HTML
               interface.

               Default: none

       publicinbox.nntpserver
               Same as "publicinbox.imapserver", but for the hostname(s) of
               the public-inbox-nntpd(1) instance.  This affects "Xref:"
               headers in responses.  As of public-inbox 2.0, this can be
               overridden on the "public-inbox-netd(1)" command-line via
               "--listen nntp://$ADDRESS:$PORT/?servername=example.com"

               Default: none

       publicinbox.pop3server
               Same as "publicinbox.imapserver", but for the hostname(s) of
               the public-inbox-pop3d(1) instance.

               Default: none

       publicinbox.pop3state
               See "publicinbox.pop3state" in public-inbox-pop3d(1)

       publicinbox.<name>.feedmax
               The size of an Atom feed for the inbox.  If specified more than
               once, only the last value is used.  Invalid values (<= 0) will
               be treated as the default value.

               Default: 25

       publicinbox.<name>.hide
               A comma-delimited list of listings to hide the inbox from.

               Valid values are currently "www" and "manifest" for non-404
               values of "publicinbox.wwwListing" and
               "publicinbox.grokManifest", respectively

               Default: none

       cindex.$NAME.topdir
       cindex.$NAME.localprefix
               See public-inbox-cindex(1)

       coderepo.<nick>.dir
               The path to a git repository for "publicinbox.<name>.coderepo"
               Absolute pathnames longer than 244 bytes cannot be indexed with
               public-inbox-cindex(1)

               Unnecessary with "--join" in public-inbox-cindex(1)

       coderepo.<nick>.cgitUrl
               The URL of the cgit instance associated with the coderepo.

               Unnecessary with "--join" in public-inbox-cindex(1)

               Default: none

       coderepo.snapshots
               See "snapshots" in cgitrc(5)

       publicinbox.cgitrc
               A path to a cgitrc(5) file.  "repo.url" directives in the
               cgitrc will be mapped to the nickname of a coderepo (without
               trailing slash), and "repo.path" directives map to
               "coderepo.<nick>.dir".  Use of this directive allows admins of
               existing cgit installations to skip declaring coderepo sections
               and map inboxes directly to code repositories known to cgit.

               Macro expansion (e.g. $HTTP_HOST) is not yet supported.

       publicinbox.cgitbin
               A path to the "cgit.cgi" executable.  The PublicInbox::WWW
               interface can spawn cgit as a fallback if the
               publicinbox.cgitrc directive is configured.

               Default: /var/www/htdocs/cgit/cgit.cgi or
               /usr/lib/cgit/cgit.cgi

       publicinbox.cgitdata
               A path to the data directory used by cgit for storing static
               files.  Typically guessed based on the location of "cgit.cgi"
               (from "publicinbox.cgitbin"), but may be overridden.

               Default: dirname of "publicinbox.cgitbin",
               /var/www/htdocs/cgit/ or /usr/share/cgit/

       publicinbox.cgit
               Controls whether or not and how "cgit" is used for serving
               coderepos.  New in public-inbox 2.0+.

               •       first

                       Try using "cgit" as the first choice, this is the
                       default.

               •       fallback

                       Fall back to using "cgit" only if our native, inbox-
                       aware git code repository viewer doesn't recognize the
                       URL.

               Default: "first"  ("cgit" will be used iff "publicinbox.cgitrc"
               is set and the "cgit" binary exists).

       publicinbox.mailEditor
               See public-inbox-edit(1)

       publicinbox.indexMaxSize
       publicinbox.indexBatchSize
       publicinbox.indexSequentialShard
               See public-inbox-index(1)

       publicinbox.wwwlisting
               Enable a HTML listing style when the root path of the URL '/'
               is accessed.  Valid values are:

               •       all - Show all inboxes

               •       404 - Return a 404 page.  This is useful to allow
                       customization with Plack::App::Cascade(3pm)

               •       match=domain - Only show inboxes with URLs which belong
                       to the domain of the HTTP request

               Default: 404

       publicinbox.nameIsUrl
               Treat the name of the public inbox as its unqualified URL when
               using "publicInbox.wwwListing=all".  That is, every
               "[publicinbox "foo"]" section implicitly sets
               "publicinbox.foo.url=foo".

               This is a convenient alternative to specifying
               "publicinbox.<name>.url" for every single inbox if your inbox
               URLs are domain-agnostic when using
               "publicInbox.wwwListing=all"

               Default: false

               New in public-inbox 2.0+

       publicinbox.grokmanifest
               Controls the generation of a grokmirror-compatible gzipped JSON
               file at the top-level of the PSGI interface.  You generally do
               not need to change this from the default.

               Valid values are:

               •       match=domain - Only include inboxes with URLs which
                       belong to the domain of the HTTP request.  This is
                       compatible with virtual hosting where several domains
                       come from the same host.

               •       all - All inboxes are present in "manifest.js.gz",
                       regardless of domain.  Only use this if you're serving
                       HTTP requests in a domain-agnostic manner.

               •       404 - "manifest.js.gz" will only contain an empty JSON
                       array.  This does NOT affect
                       "$INBOX_URL/manifest.js.gz", which will always contain
                       all git repos used by the inbox at $INBOX_URL

               Default: "match=domain"

       publicinbox.<name>.obfuscate
               Whether to obfuscate email addresses in the PublicInbox::WWW
               HTML interface.

               Default: false

       publicinbox.noObfuscate
               A space-delimited list of well-known addresses and domains that
               should not be obfuscated when "publicinbox.$NAME.obfuscate" is
               true (e.g., "public@example.com" and "@example.com").  This may
               be specified more than once, in which case the values are
               merged.

               Default: none

       extindex.<name>.topdir
               The directory of an external index.  See
               public-inbox-extindex(1) for more details.

       extindex.<name>.url
               Identical to "publicinbox.<name>.url", but for external indices

       extindex.<name>.coderepo
               Identical to "publicinbox.<name>.coderepo", but for external
               indices.  Code repos may be freely associated with any number
               of public inboxes and external indices.

   NAMED LIMITER (PSGI)
       Named limiters are useful for preventing large inboxes from
       monopolizing (or overloading) the server.  Since serving git clones
       (via git-http-backend(1) can be memory-intensive for large inboxes, it
       makes sense to put large inboxes on a named limiter with a low max
       value; while smaller inboxes can use the default limiter.

       "RLIMIT_*" keys may be set to enforce resource limits for a particular
       limiter (BSD::Resource(3pm) is required).

       Default named-limiters are prefixed with "-".  Currently, the "-cgit"
       named limiter is reserved for instances spawning cgit via
       "publicinbox.cgitrc".  The "-httpbackend" named limiter (in public-
       inbox 2.0+) governs all git-http-backend(1) processes for inboxes and
       coderepos for a given public-inbox config file.  The "-codeblob"
       limiter (in 2.0+) governs the entire series of git commands used for
       blob reconstruction from patches.

       publicinboxlimiter.<name>.max
               The maximum number of parallel processes for the given limiter.

               Default: 32 for "-httpbackend", 1 for everything else

       publicinboxlimiter.<name>.depth
               The maximum queue depth for the given limiter.  HTTP 503 errors
               will be returned when the queue depth is exceeded.

               Default: 32

               New in public-inbox 2.0+

       publicinboxlimiter.<name>.rlimitCore
       publicinboxlimiter.<name>.rlimitCPU
       publicinboxlimiter.<name>.rlimitData
               The maximum core size, CPU time, or data size processes run
               with the given limiter will use.  This may be comma-separated
               to distinguish soft and hard limits.  The word "INFINITY" is
               accepted as the RLIM_INFINITY constant (if supported by your
               OS).

               See setrlimit(2) for more info on the behavior of RLIMIT_CORE,
               RLIMIT_CPU, and RLIMIT_DATA for you operating system.

       EXAMPLE WITH NAMED LIMITERS

               ; big inboxes which require lots of memory to clone:
               [publicinbox "big1"]
                       inboxdir = /path/to/big1
                       address = big1@example.com
                       httpbackendmax = big
               [publicinbox "big2"]
                       inboxdir = /path/to/big2
                       address = big2@example.com
                       httpbackendmax = big

               ; tiny inboxes which are easily cloned:
               [publicinbox "tiny1"]
                       inboxdir = /path/to/tiny1
                       address = tiny1@example.com
               [publicinbox "tiny2"]
                       inboxdir = /path/to/tiny2
                       address = tiny2@example.com

               [publicinboxlimiter "big"]
                       max = 4

       In the above example, the "big1" and "big2" are limited to four
       parallel git-http-backend(1) processes between them.

       However, "tiny1" and "tiny2" will share the default limiter which means
       there can be 32 git-http-backend(1) processes between them.
