Hi!
I am sharing my Conkeror configuration between several computers and I
would like some configuration settings to be specific to a
host. Usually, this means adding a condition the hostname.
I did not find any function that would return me the hostname. I have
nothing in the environment variables that contain the hostname and I
would like to avoid to add one.
I have tried to use `shell_command` but it uses coroutines and I didn't
find a way to execute coroutines synchronously outside of a coroutine. I
have tried this:
#v+
function hostname() {
var output = "";
var result = shell_command("uname -n",
$fds = [{ output: async_binary_string_writer("")
},
{ input: async_binary_reader(function
(s) output += s )},
{ input: async_binary_reader(function
(s) null)}]);
try {
while (true) result.next();
} catch (e if e instanceof StopIteration) {
return output;
}
};
#v-
But this does not work. I get an empty string.
Any idea?
