Leading and trailing whitespace +and everything after the first \fB#\fP on any line will be trimmed, and +empty lines will be ignored. +.PP +The trigger control directives currently supported are: +.TP +\fBinterest\fP \fItrigger-name\fP +.TQ +\fBinterest\-await\fP \fItrigger-name\fP +.TQ +\fBinterest\-noawait\fP \fItrigger-name\fP +.IP +Specifies that the package is interested in the named trigger. All +triggers in which a package is interested must be listed using this +directive in the triggers control file. +.IP +The “await” variants put the triggering package in triggers\-awaited +state depending on how the trigger was activated. +The “noawait” variant does not put the triggering packages in +triggers\-awaited state, even if the triggering package declared an +“await” activation (either with an \fBactivate\-await\fP or \fBactivate\fP +directive, or by using the \fBdpkg\-trigger\fP \fB\-\-no\-await\fP +command-line option). +The “noawait” variant should be used when the functionality provided +by the trigger is not crucial. +.TP +\fBactivate\fP \fItrigger-name\fP +.TQ +\fBactivate\-await\fP \fItrigger-name\fP +.TQ +\fBactivate\-noawait\fP \fItrigger-name\fP +.IP +Arranges that changes to this package's state will activate the +specified trigger. The trigger will be activated at the start of +the following operations: unpack, configure, remove (including for +the benefit of a conflicting package), purge and deconfigure. +.IP +The “await” variants only put the triggering package in triggers\-awaited +state if the interest directive is also “await”. +The “noawait” variant never puts the triggering packages in +triggers\-awaited state. +The “noawait” variant should be used when the functionality provided +by the trigger is not crucial. +.IP +If this package disappears during the unpacking of another package +the trigger will be activated when the disappearance is noted +towards the end of the unpack. Trigger processing, and transition +from triggers\-awaited to installed, does not cause activations. +In the case of unpack, triggers mentioned in both the old and new +versions of the package will be activated. +.PP +Unknown directives are an error which will prevent installation of the +package. +.PP +The “\-noawait” variants should always be favored when possible since +triggering packages are not put in triggers\-awaited state and can thus +be immediately configured without requiring the processing of the trigger. +If the triggering packages are dependencies of other upgraded packages, +it will avoid an early trigger processing run and make it possible +to run the trigger only once as one of the last steps of the upgrade. +.PP +The “\-noawait” variants are supported since dpkg 1.16.1, and +will lead to errors if used with an older dpkg. +.PP +The “\-await” alias variants are supported since dpkg 1.17.21, and +will lead to errors if used with an older dpkg. +.PP +When a package provides an \fBinterest\-noawait\fP directive, any activation +will set the triggering package into “noawait” mode, regardless of the +awaiting mode requested by the activation (either “await” or “noawait”). +When a package provides an \fBinterest\fP or \fBinterest\-await\fP directive, +any activation will set the triggering package into “await” or “noawait“ +depending on how it was activated. +. +.SH SEE ALSO +.BR dpkg\-trigger (1), +.BR dpkg (1), +.\" FIXME: Unhardcode the pathname, and use dpkg instead of dpkg-dev. +.BR /usr/share/doc/dpkg\-dev/triggers.txt.gz . -- cgit v1.2.3
