# In application/:
# Capitalize all class names inside models and controllers (and helpers):

find ./ -name \*.php -exec gsed  -i "s/helper_\([a-zA-Z]\+\)/Helper_\u\1/gI" {} \;
find ./ -name \*.php -exec gsed  -i "s/helper_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Helper_\u\1_\u\2/gI" {} \;
find ./ -name \*.php -exec gsed  -i "s/helper_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Helper_\u\1_\u\2_\u\3/gI" {} \;

# Same for classes starting with Model_ and Controller_:
find ./ -name \*.php -exec gsed  -i "s/model_\([a-zA-Z]\+\)/Model_\u\1/gI" {} \;
find ./ -name \*.php -exec gsed  -i "s/model_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Model_\u\1_\u\2/gI" {} \;

# Now some class names that were used with only 1 capital, are now written in full capitals (Html, Url, Http, UTF8).
# Replace them in your whole application:
find ./ -name \*.php -exec gsed -i "s/Url::/URL::/gI" {} \;
find ./ -name \*.php -exec gsed -i "s/Html::/HTML::/gI" {} \;
find ./ -name \*.php -exec gsed -i "s/Http::/HTTP::/gI" {} \;
find ./ -name \*.php -exec gsed -i "s/Utf8::/UTF8::/gI" {} \;

# When you use the ORM driver, all Orm::factory('some_class') should be upper cased
# and capitalised to ORM::factory('Some_Class'):
find ./ -name \*.php -exec gsed -i  "s/orm::factory(\(\"\|'\)\([a-zA-Z_]\+\)\(\"\|'\)\(,[^,]*\)*)/ORM::factory('\u\2'\4)/gI" {} \;
find ./ -name \*.php -exec gsed -i  "s/orm::factory(\(\"\|'\)\([a-zA-Z]\+\)_\([a-zA-Z]\+\)\(\"\|'\)\(,[^,]*\)*)/ORM::factory('\u\2_\u\3'\5)/gI" {} \;

Replace all occurences of:
  Request::current()->redirect
with:
  HTTP::redirect
