I was able to use jsonx by adding it to the list of dependencies in
rebar.config and then replacing the 4 uses of mochijson2:encode in
src/boss/boss_json.erl
It seems to work, I'm not sure if I have missed anything, but everything
seems to have worked.
I also got jsone to work by:
Editing ChicaagoBoss/rebar.config
1. add, at the end of the maintained by others section, the following
dependency
{jsone, ".*", {git, "git://github.com/sile/jsone.git", {tag,
"v0.3.3-hipe"}}}
Editing ChicagoBoss/src/boss/boss_json
1. replace mochijson2:encode with jsone:encode
2. json_data1([], _, Acc) ->
{struct, lists:reverse(Acc)}; <- make this line {lists:reverse(Acc)};
Editing
ChicagoBoss/src/boss/model_manager_adapters/boss_model_manager_boss_db.erl
1. the final clause of to_json(Object) function changes from
{struct, Data}. to
{Data}.
