To list:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw —listapps

To add an application to the firewall:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw --add /Users/clarkeb/go/src/github.com/gowiki/wiki

To get the state of application that has been added to the firewall:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getappblocked /Users/clarkeb/go/src/github.com/gowiki/wiki

To unblock an application that has been added to the firewall:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw —unblockapp /Users/clarkeb/go/src/github.com/gowiki/wiki

So, when regularly compiling a binary, run the following each time to save time:

sudo /usr/libexec/ApplicationFirewall/socketfilterfw --remove /Users/clarkeb/go/src/github.com/gowiki/wiki && \ 
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --add /Users/clarkeb/go/src/github.com/gowiki/wiki && \ 
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --unblock /Users/clarkeb/go/src/github.com/gowiki/wiki
