# A shell script for an Xcode 5 behavior to automatically check out a file
# whenever it is "unlocked" (made writable) in Xcode.
#
# Full instructions for setting up this script can be found at:

## Set the timeout interval for dismissing the dialog:
to=10

## Turn on all feedback (messages).
## If set to 1, the "p4 edit" command result is displayed
##  when unlocking a file from Xcode.
## If set to 0, the file is unlocked and checked out of Perforce
## silently (messages and errors will still be logged to console):
fb=1
 
# Xcode doesn't setup the environment, so we load it here:
source ~/.bashrc
source ~/.bash_login

fn=${XcodeAlertAffectedPaths}
fn=$(printf $(echo -n $fn | sed 's/\\/\\\\/g;s/\(%\)\([0-9a-fA-F][0-9a-fA-F]\)/\\x\2/g') )
echo "fp=" ${fn}

# Get the enclosing directory for the file being unlocked:
fp=$(dirname "${fn}")
echo "fp=" ${fp}
 
# A check to confirm the current P4CONFIG setting:
conf=$(/usr/local/bin/p4 -d "${fp}" set P4CONFIG 2>&1)
echo ${conf}

if [ -a "${fn}" ]; then
 
    # Save the dialog timeout to an environment variable:
    export XC_TO=${to}
 
    # Check the file out from Perforce:
    res=$(/usr/local/bin/p4 -d "${fp}" edit "${fn}" 2>&1)
    echo "res=" ${res}
 
    # Save the result as an environment variable
    export XC_RES=${res}
 
    if [ ${fb} -gt 0 ]; then
 
        # Tell Xcode to display a dialog to with the result of the command.
        # The timeout is set by '${to}', above:
        ~/Documents/dev/scripts/xcodeunlock_suc.sh &
    fi
else
    echo "FnF" "${fn}"
fi


#export XC_TO=${to}
#osascript -e "tell application \"Finder\" to display dialog (system attribute \"XC_P4_DEBUG\") buttons {\"OK\"} default button 1 giving up after (system attribute \"XC_TO\")"

Thank you!

This solved my issue with Xcode hanging when trying to check out files.

It also led me to my current solution, which is just to execute the original AppleScript from perforce inline with an & at the end of the line like so:

osascript -e "tell application \"xcode\" to display dialog (system attribute \"XC_RES\") with icon 1 buttons {\"OK\"} default button 1 giving up after (system attribute \"XC_TO\")" &
