Question

I’d like to introduce build number feature for my iPhone project and increase it automatically with every commit to my git repo. I plan to do it using Apple’s agvtool, which recommends that project is not opened in XCode at the time

So my questions are:
1) So far I know that I need to make an executable script from .git/hooks/pre-commit.sample. How to do the scripting to check if certain project is opened in XCode?

2) pre-commit.sh will be executed upon calling git commit with no args, so whenever someone will commit with -a option, I won’t have my build number updated. Is there any way to workaround this?

Cheers

Xcode supports AppleScript. I tested this with Xcode 4.2 but I think it ought to work in earlier releases.

First, write a script file, isXcodeProjectOpen.scpt:

-- Returns 1 if a project in the given directory is open, otherwise 0
on run argv
    set _path to first item of argv
    tell application "Xcode"
        repeat with _p in projects
            if project directory of _p is _path then
                return 1
            end if
        end repeat
    end tell
    return 0
end run

Then you can run that from the shell like this:

ISOPEN=`osascript isXcodeProjectOpen.scpt /path/containing/project`
if [ -z $ISOPEN ]; then
   # all clear
else
   # not safe to run agvtool!
