Hi all,

I'm interested whether there exists a library for working with JSON in Boost that preserves data types?

I know about property_tree, but if I read a valid JSON with it and then write it out it results in all fields being strings. This is because property_tree internally does not distinguish different value types. But I need something that can read e.g.

{"number":42}

get access to it and write it then in the same form.

You may check https://github.com/cierelabs/json_spirit developed by the Spirit team. Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

I used to use json_spirit, but I recently switched to libjsoncpp. It's not boost, but I like it better. Rgds Richard On Mo, 2013-11-04 at 21:01 +0100, Jauhien Piatlicki wrote:
