Very helpful. Thanks!

I extended the script a bit more to search for the struct and insert the
fragment, as follows:
#!/bin/bash
sed -n '/^static const TypeInfo.*$/,/^};.*$/p' $1 | \
grep "\(\.instance_size\|\.name\)"\
> typeinfo.tmp
cat typeinfo.tmp
STRING=$(grep -o "\".*\"" typeinfo.tmp | sed 's/\"//g')
echo
echo "String is ${STRING}"
echo
sed "s/\"${STRING}\"/TYPE_${2}/g" -i ${1}
git diff ${1} | cat
STATE_STRUCT=$(grep -o "(.*)" typeinfo.tmp | sed "s/(//" | sed "s/)//")
echo "State Struct is ${STATE_STRUCT}"
echo "------------------ cut here ------------------------"
echo "#define TYPE_${2} \"${STRING}\""
echo ""
echo "#define ${2}(obj) \\"
echo " OBJECT_CHECK(${STATE_STRUCT}, (obj), TYPE_${2})"
found=""
grep "^.*struct ${STATE_STRUCT} *{" ${1}
if [ $? -eq 0 ]; then
found=${1}
else
files=$(sed -n "s/^#include \"\(.*\)\"/\1/ p" ${1})
for f in $(echo $files); do
f=$(echo "include/$f")
grep "^.*struct ${STATE_STRUCT} *{" ${f}
if [ $? -eq 0 ]; then
found=${f}
break
fi
done
fi
if [ "${found}" == "" ]; then
echo "not found file."
exit 1
fi
# define TYPE_FOO
sed -i "/^.*struct ${STATE_STRUCT} *{\$/i#define TYPE_${2} \"${STRING}\""
${found}
sed -i "/^.*struct ${STATE_STRUCT} *{\$/i\\\n" ${found}
sed -i "/^.*struct ${STATE_STRUCT} *{\$/i#define ${2}(obj) \\\\" ${found}
sed -i "/^.*struct ${STATE_STRUCT} *{\$/i\ \ \ \ OBJECT_CHECK(${STATE_STRUCT},
(obj), TYPE_${2})" ${found}
sed -i "/^.*struct ${STATE_STRUCT} *{\$/i\\\n" ${found}
