Sorry, I don't understand what «without the REPL prompt and stuff» means :-) I wrote Guile-Daemon because I needed a general-purpose guile process running all the time to which I can send expressions for evaluating. So I run 'guile-daemon', and then I can do something like this: echo '(something #:useful? #t)' > /path/to/daemon-fifo-file Actually there is 'gdpipe' shell script that does this redirection: gdpipe '(something #:useful? #t)' As for 'guile --listen', yes, Guile-Daemon also starts a socket to which you can connect with "M-x geiser-connect-local" or alike. If anyone is interested, I use it as an OSD daemon, particularly to set sound volume/muteness and to display it using Guile-XOSD. Here is a small demo: https://raw.github.com/alezost/guile-daemon-config/master/sound-volume-demo.gif My Guile-Daemon config: <https://github.com/alezost/guile-daemon-config>. -- Alex
