A simple IPC server for StumpWM
This is a simple IPC server for StumpWM, with an accompanying C client. This was written mainly to make myself familiar with unix domain sockets; StumpWM already has an IPC method based upon X11 atoms.
The lisp server can be quickloaded, and the server started with the function
#'simple-ipc-server:start-server. The client can be built by the usual
./autogen.sh ./configure make make install. After building, run
swmipc --help for a list of options and their descriptions.
The swmipc executable can send commands to be executed as well as lisp forms
to be evaluated. To evaluate lisp forms the variable
simple-ipc-server:*allow-evaluation* must be T. There is also an
interactive mode which reads input from the user and sends the appropriate
request.
When reading commands from stdin every line is treated as a single command invocation.
During evaluation, standard output is bound to the socket stream, and printing to standard output will print back to swmipc.
