Question

I have a game which has xml files in it. My game works on iPad and on iPhone, and i need to perform some changes in these xml files accordingly, but the xml files are original and i do not want them changed, so what i want is have my xml files changed automatically at compile time. For this purpose i have a ruby script which does what i need.
Let’s say this script is level_converter.rb
which i can execute(in terminal) as follows:

for f in Resources/*.xml; do ruby level_converter.rb "$f"; done

So i added this code to Build Phases to Run Script this way and this does work as expected, it does change all the xml files properly, BUT ofcourse it changes the original xml files in the resources foler. So say if i run twice – i’ll have these files changed twice. What i want is these files stay not changed but only those deployed should change. So i need some kind of $(PROJECT_DISTRIBUTION_AND_DEVELOPEMENT_TEMP_FOLDER) or something like that instead of simply Resorces/*.xml eg.

for f in $(PROJ_DISTRIB_AND_DEV_TMP_FLDE)/*.xml; do ruby level_converter.rb "$f"; done

edit: must be im not that clear with the question, so i’ve rephrased it

Answer 1

i was able to achieve what i wanted, here is the script:

PROJ_DIR=${PWD}

echo "Converting xml files..."
for f in "${CODESIGNING_FOLDER_PATH}/"*.xml
do
    cp $PROJ_DIR/Resources/"${f##*/}" "$f"
    ruby level_converter.rb "$f" $PROJ_DIR/key_hash;
done

exit 0;

So i used this ${CODESIGNING_FOLDER_PATH} variable.

explanation:

• the for iterates the *.xml files in the destination directory
• cp $PROJ_DIR/Resources/”${f##*/}” “$f”: as far as xcode only copies resources only if they were changed i have to manually copy the xml files to prevent them being converted more then once – so the converter is executed each build and so it should have original files in place to convert
• ruby level_converter.rb “$f” $PROJ_DIR/key_hash; : this simply executes the script

this does what i wan’t but there are drawbacks/doubts:

• from time to time i get a warning that the signed resources where changed or removed (well that doesn’t surprise me though). Maybe there is a way to supress this? It does stop the app being sandboxed and i have to build again and hope there will be no warning next time. Lucky me it does not appear often
• building takes much longer, it would still be nice to figure if the original files where changed and only execute the script if necessary
• i still think there should be some “proper” way to achieve what i wanted
• i am not sure i’ve picked up the variable CODESIGNING_FOLDER_PATH correctly, maybe i should use another one

edit: i moved the run script to be run before compiling source code, and didn’t get any warnings about signed resources changed since then. Wandering if that’s the cause
