Note that I am using Miro 2.5 due to be released as an ubuntu deb sometime in the next week.
For whatever reason, the miro command does not work correctly when called from a cairo-dock launcher.
The only way I got this to work was to write a little php script as a wrapper. In order to run php scripts you'll need to install php5-cli
From a terminal
sudo aptitude install php5-cli
Now we need to write the script.
From a terminal
gksu gedit /usr/local/bin/miro.launcher
Since /usr/local/bin requires root for write access, we use gksu and it will ask for your password.
Paste the following into gedit
#!/usr/bin/php -q
<?php
passthru("miro.real > /dev/null 2>&1");
?>
Now save and close gedit. Next we need to make this script executable.
From a terminal
sudo chmod +x /usr/local/bin/miro.launcher
Now configure a cairo-dock launcher. In the command field, use
miro.launcher
I'll leave the rest of the configuration up to you.
For those that want to understand the script, here's a breakdown:
Line 1 just tells the system what program should be used as the interpreter for the script.
Lines 2 and 4 are opening and closing tags between which the php interpreter will execute the contents as php commands. Without these tags, the interpreter would just output whatever text happens to be there.
Line 3 is a php function which executes a command on the system. For more details on this function see here (http://us2.php.net/manual/en/function.passthru.php).
The command it is executing is
miro.real > /dev/null 2>&1
miro.real launches miro. the > /dev/null tells it to send it's standard output to the null device (http://en.wikipedia.org/wiki//dev/null). The 2>&1 tells it to send standard error message to the same place as the standard output, which in this case is the null device.
I find it's good practice to send any unneeded output to the null device.
