A terminal based utility for storing/restoring jack connection states.

This is the README:

Introduction:

jack_snapshot - a little tool for storing/restoring jack connection states.
it does this by writing/reading the names of the connected ports into/from a
simple textfile. and here is also one weakness: some jack clients don’t use the
same jack name on each run, but dynamically assign one (like meterbridge)
but most of them can be told to use a specific name, so this isn’t really a
problem. at least not for me. some pattern matching might be added in the
future. Patches happily accepted.

Installation:

run

make

    $ make
    g++ jack_snapshot.cc -o jack_snapshot `pkg-config jack –libs`
    jack_snapshot.cc: In function ‘int main(int, char**)’:
    jack_snapshot.cc:21: error: ‘exit’ was not declared in this scope
    jack_snapshot.cc:35: error: ‘exit’ was not declared in this scope
    jack_snapshot.cc:113: error: ‘strncpy’ was not declared in this scope
    make: *** [jack_snapshot] Error 1

    After adding the following to the include section of jack_snapshot.cc
    it compiles.

    #include
    #include

    seems to be a GCC 4.3 issue

    thanks for this helpful little tool!

    oops, the header names got eaten by the markup, they are:

    string.h
    cstdlib

    the option is a double - ! In my browser it looks like only one, but it only works right with 2: — ; so this is fine:
    /mnt/linux-nobi/jack_snapshot-0.0.3/jack_snapshot restore ~/onlyone.snapshot –noclear

    by problems during compiling, check Davids reply and do the 2 include in the cc code.

    thanks for sharing this useful code to Florian Schmidt.

    for the jack.h-include you need some jack-library: libjack or some other jack-audio-connection-kit
