[PATCH 0/3] 3 packages for my programs

[Alex Kost]

Hello, I use these programs all the time, so I think maybe they could be
useful for someone else.  Is it reasonable to add these packages to
Guix?

[PATCH 1/3] gnu: Add xdpyprobe.
[PATCH 2/3] gnu: Add guile-xosd.
[PATCH 3/3] gnu: Add guile-daemon.

[PATCH 1/3] gnu: Add xdpyprobe.

This looks a lot like ‘guile --listen’, except without the REPL prompt
and stuff, right?

Thanks,
Ludo’.

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:

‘guile --listen’ gives you a REPL prompt, which is nice for interactive
stuff, but less nice for scripting.

Understood, it does sound useful.

Pretty neat!
