Dependencies
Jansson
Jansson is a C library for encoding, decoding and manipulating JSON data.
HDF5
HDF5 is a set of software libraries and self-describing,
machine-independent data format that support the creation,
access, and sharing of array-oriented scientific data.
zlib
zlib is a software library used for data compression.
Building from source

Building from source
Makefile for Ubuntu i386 GNU/Linux
make -f makefile make -f makefile test

Building with CMake in Unix
On most Unix systems, the Jansson, HDF5 and zlib libraries are found on the default location with
cd build cmake ..
CMake build options
If the Jansson, HDF5 and zlib libraries are found on the default location, they can be set.
cmake .. \ -DJANSSON_INCLUDE:PATH=/your/jansson/include/path \ -DJANSSON_LIBRARY=/your/jansson/library/file/name \ -DHDF5_INCLUDE:PATH=/your/hdf5/include/path \ -DHDF5_LIBRARY=/your/hdf5/library/file/name \ -DZLIB_LIBRARY=/your/zlib/library/file/name \ -DSZIP_LIBRARY=/your/zlib/library/file/name
For a Windows Visual Studio build a statically build runtime library can be set with.
cmake .. -DSTATIC_CRT:BOOL=ON
Usage
./star_json 'JSON file in ./data'
Examples
A file with 1 group named "g1" that has 2 subgroups "g11" and "g12" with no children
{
"g1":{
"g11":"group",
"g12":"group"
}
}
}
A file with 1 dataset named "dset1", with numerical type STAR_INT32 (signed 32 bit integers), with a rank of value 2, with dimensions of values 3 and 4, and the data values from 1 to 12
{
"dset1": [{
"dset1": ["dataset", "STAR_INT32", 2, [3, 4],[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]]
}]
}
