$ json2cbor < in.json > out.cbor                  # JSON to CBOR
$ cbor2json < in.cbor > out.json                  # CBOR to JSON
$ cat in.cbor | cbor2json | json2json > out.json  # CBOR to pretty JSON

The implementation strictly complies with RFC8259 / ECMA-404.

The implementation complies with RFC7049.

I2O requires C++11 compliant compiler. C++17 compliant compiler with <charconv> (P0067R5) support is recommended for best performance.
The only dependency, besides the standard library is the CXON library.

I2O can be built and installed using the included makefile on POSIX systems:

$ git clone https://github.com/oknenavin/cxon.git
$ sudo make -C cxon install
$ git clone https://github.com/oknenavin/i2o.git
$ sudo make -C i2o install

The default installation directory is /usr/local/bin and can be altered with DESTDIR and prefix variables, for example:

$ git clone https://github.com/oknenavin/cxon.git
$ sudo make -C cxon DESTDIR=~ prefix=/. install
$ git clone https://github.com/oknenavin/i2o.git
$ sudo make -C i2o DESTDIR=~ prefix=/. install

will install CXON and I2O in ~/include and ~/bin respectively.

Because CXON is a header-only library, you may skip its installation:

$ git clone https://github.com/oknenavin/cxon.git
$ git clone https://github.com/oknenavin/i2o.git
$ sudo make -C i2o CXXFLAGS="../cxon/src" install

or just build it in place:

$ git clone https://github.com/oknenavin/cxon.git
$ git clone https://github.com/oknenavin/i2o.git
$ make -C i2o CXXFLAGS="../cxon/src" # the binaries are in i2o/.out
