plash-socket-publish — Make a Plash object reference available via a named socket
plash-socket-publish =>socket-pathname
/x=variable-name
This program makes a reference to a single Plash object available via a Unix domain socket -- that is, a named socket that appears in the filesystem. This is useful for exporting an object that has been bound to a variable in one instance of the Plash shell, so that it can be used in other instances of the shell (eg. in a different terminal window).
It can be used in conjunction with plash-socket-connect, which connects to a socket and returns a copy of the reference that the socket exports.
If a socket already exists at socket-pathname
, the program
removes it first. (However, it will give an error if a file exists
under that name.)
This command is only useful when used in the Plash shell.
The process has to stick around as a proxy to forward method calls.
The program can't tell when it can never receive any more connections -- ie. when the socket has been deleted from the filesystem or replaced -- so it runs indefinitely. You have to stop the program manually.
