Extracts private methods from a .m class file and creates a Class+Private.h class extension - somehow turning this into an Xcode plugin would also be cool.

private_header

#!/bin/bash

# change PREFIX to match whatever you use to denote private
# methods internally in .m files
# e.g.
# - (void)_privateMethod
PREFIX="_"

if [ $# -eq 0 ]
then
    echo "usage: $0 <class_file>.m"
    echo
    echo "outputs a Class+Private.h file with internal private method"
    echo "signatures as determined by the defined method prefix"
    exit 1
fi

if [ ! -f $1 ]
then
    echo "$1 is not a file. Aborting."
    exit 1
fi

FILE=`basename $1`
CLASS="${FILE%.*}"


OUTFILE="$CLASS+Private.h"

echo "#import \"$CLASS.h\"" > $OUTFILE
echo >> $OUTFILE

echo "@interface $CLASS ()" >> $OUTFILE
echo >> $OUTFILE

egrep "^[-+][ ]?\(.*\)[ ]?$PREFIX" $1 | awk '{print $0 ";"}' | sort >> $OUTFILE

echo >> $OUTFILE
echo "@end" >> $OUTFILE

cat $OUTFILE

Thanks. I could really use this.
