jack-plumbing \- JACK Plumbing Daemon
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
jack\-plumbing [options] [rule\-files]
|
|
.SH "OPTIONS"
|
|
.sp
|
|
\fB\-d\fR : Do not operate as a daemon\&.
|
|
.sp
|
|
\fB\-o\fR : Do not load ordinary rule files\&.
|
|
.sp
|
|
\fB\-q\fR : Quiet operation\&.
|
|
.sp
|
|
\fB\-u\fR : Set the time, in micro\-seconds, that must elapse after a connection notification to indicate the end of a notification set (default=30000)\&. This is an optimization switch\&.
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
jack\-plumbing maintains a set of port connection rules and manages these as clients register ports with JACK\- Port names are implicitly bounded regular expressions and support sub\-expression patterns\&.
|
|
.sp
|
|
There are four rules: connect, disconnect, also\-connect and connect\-exclusive\&.
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
(connect "SuperCollider:out_(\&.*)" "system:playback_\e1")
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
This connect rule ensures that whenever scsynth(1) is running any output ports it registers are connected to appropriate ALSA playback ports\&. The connect rule only makes a connection if none already exist\&.
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
(also\-connect "system:playback_1" "jack\-udp\-[0\-9]*:in_1")
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
This also\-connect rule ensures that when jack\-udp(1) is running in send mode all signals that are ordinarily sent to the local audio interface will also be sent to the network destination\&. The also\-connect aliasing applies to both the left and right hand side of connect rules\&.
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
(connect\-exclusive "SuperCollider:out_(\&.*)" "ardour:sc3_in_\e1/in 1")
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.sp
|
|
This connect\-exclusive rule ensures that if SuperCollider and an ardour(1) session with appropriate tracks are both running that SuperCollider gets connected to ardour and disconnected from everything else\&.
|
|
.sp
|
|
This type of connection daemon has the following advantages over both environment variables and command line arguments:
|
|
.sp
|
|
.RS 4
|
|
.ie n \{\
|
|
\h'-04'\(bu\h'+03'\c
|
|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP \(bu 2.3
|
|
.\}
|
|
it does not require any client connection support or logic at all
|
|
.RE
|
|
.sp
|
|
.RS 4
|
|
.ie n \{\
|
|
\h'-04'\(bu\h'+03'\c
|
|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP \(bu 2.3
|
|
.\}
|
|
it provides a uniform user interface to all clients

.ie n \{\

\h'-04'\(bu\h'+03'\c
|
|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP \(bu 2.3
|
|
.\}
|
|
it has a somewhat declarative style
|
|
.RE
|
|
.sp
|
|
This type of daemon is very lightweight and non\-intrusive: it requires no arguments, it runs from an unprivileged thread, if the rule set is empty it is a no\-op, it does not write any files, it does not require any modification to clients or to how clients are started\&.
|
|
.sp
|
|
When a set of port registrations is made it checks the modification time of the rule set files, \fI/etc/jack\-plumbing\fR and \fI~/\&.jack\-plumbing\fR, and any files specified by the user, rereads the rule set if it has been updated, then makes the JACK graph obey the rules\&.
|
|
.sp
|
|
Any lines beginning with a semi\-colon are ignored\&.
|
|
.sp
|
|
The rule set is sorted, disconnect rules are applied first, then connect rules, then connect\-exclusive rules\&.
