An unworthy mongo library for Idris

If mongo drivers are not installed:

brew update curl -LO https://github.com/mongodb/mongo-c-driver/releases/download/1.12.0/mongo-c-driver-1.12.0.tar.gz tar xzf mongo-c-driver-1.12.0.tar.gz cd mongo-c-driver-1.12.0 brew install cmake mkdir cmake-build cd cmake-build cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF .. make sudo make install

export paths

export CPATH=/usr/local/include/libmongoc-1.0:/usr/local/include/libbson-1.0:/usr/local/lib/ export LD_LIBRARY_PATH=/usr/local/lib/

#build idris --build mongolib.ipkg

start mongodb

mongod -vvvvv --config /usr/local/etc/mongod.conf

idris-mongo's Issues

Memory leak in bson_as_json

The bson_as_json C stub returns a char *. The documentation of BSon states that such strings/pointers must be deallocated with free(). However the pointer becomes owned by Idris when returning from the call to the C stub. As far as I see it, Idris doesn't free() the pointer.
