This information is required to apply patches from an archive to a local code repository (@pxref{Applying patches}). +@findex piem-merged-inboxes +@vindex piem-get-inboxes-from-config +If you mirror some inboxes locally (e.g., for fast local access or for +use with lei), you don't need to duplicate the information from your +public-inbox configuration +(@url{https://public-inbox.org/public-inbox-config.txt,public-inbox-config(5)}). +When the option @code{piem-get-inboxes-from-config} is non-nil, the +function @code{piem-merged-inboxes}, which all code should use for +accessing the registered inboxes, returns a combined set of inboxes +derived from @code{piem-inboxes} and public-inbox's configuration. +Merging is done at the level of inbox properties (e.g., an inbox's URL +may be defined in @code{piem-inboxes} and the inbox's address in +public-inbox's configuration). When a value is defined in both sources, +the one in @code{piem-inboxes} takes precedence. + +Properties described for @code{piem-inboxes} are constructed by mapping + +@example +[publicinbox $inbox] +$name = $value +@end example + +@noindent +to + +@example + ($inbox :$name $value ...) +@end example + +@noindent +The one exception is @code{:coderepo}. In public-inbox's configuration, +the value of @code{publicinbox.$inbox.coderepo} points to another +configuration option, @code{coderepo.$value.dir}, which in turn points +to a repository's git directory. The @code{:coderepo} of +@code{piem-inboxes}, however, should be set to the @emph{working tree}, +so @code{:coderepo} is derived from the value of +@code{coderepo.$value.dir}, stripping a trailing @file{/.git} if +present. + +@findex piem-clear-merged-inboxes +Note that @code{piem-merged-inboxes} reads from the public-inbox +configuration once, generates the merged set of inboxes, and then caches +the result. If you change @code{piem-inboxes} outside the customize +interface or change public-inbox's configuration, you need to call the +command @code{piem-clear-merged-inboxes} to clear the cache. + @node Enabling integration libraries @section Enabling integration libraries @findex piem-elfeed-mode |
