lash_wrap

NAME

lash_wrap - a small LASH wrapper for non-LASH apps

SYNOPSIS

lash_wrap [options] -- [commandline to start the wrapped app]

DESCRIPTION

Lash-Wrap is a small helper application that serves as a "proxy" between an un-LASH'ified app and the LASH Audio Session Handler.

Lash-Wrap enables automatic Jack and Alsa connection handling/restoring by passing the wrapped application's Jack and Alsa id's to the LASH server. Next time the LASH project is loaded the connections are restored like when dealing with a native LASH client.

Restoring files/projects is also possible if the wrapped application has a command line option to load files/projects. The load option has to be given when the application is first brought to a LASH project with Lash-Wrap even though the file/project wouldn't exist yet. Saving has to be done manually in the wrapped app (this is a good thing to remember before closing the LASH session). To imitate a real LASH client the project/file should be saved to the LASH project directory.

OPTIONS

-h [ --help ]

produce help message

-v [ --version ]

show version

-l [ --lash-name ] arg

Set LASH client name.

-j [ --jack-name ] arg

Set jack client name.

-a [ --alsa-name ] arg

Set alsa seq client name.

-i [ --alsa-id ] arg

Set alsa seq client id.

-d [ --jack-name-send-delay ] arg

Set the delay time in seconds until the jack client name is sent after lash_wrap found a corresponding port (default 5(s)).

-t [ --search-timeout ] arg

Set the timeout time in seconds until lash_ wrap gives up searching for the alsa seq id, alsa client name or jack client name (default 30(s)). Use -1 for no timeout.

-s [ --shutdown-timeout ] arg

Set the timeout time in seconds until lash_ wrap gives up waiting for the guest process to stop. First it is sent a SIGTERM, then the shutdown-timeout time is waited, then a SIGKILL is sent (default 5(s)).

-p [ --probe-client-names ]

Try to probe startup command with correct Jack and/or Alsa client names and exit. Uses a search-timeout value of 10(s) by default. Use -t option to alter timeout. Produces a lash_wrap command with the probed client names as an output.

EXAMPLES

Starting a LASHified Ardour with a project file:

lash_wrap --jack-name ardour --alsa-name ardour -- ardour2 /media/sound/ardour/foo/foo.ardour

Probing client names and startup command for Phasex (produces the command in the next example):

lash_wrap --probe-client-names -- phasex

Starting a LASHified Phasex using short option names:

lash_wrap -l phasex -j "phasex" -a "PHASEX Synthesizer" -- phasex
