Reading attributes from datasets returns weird results about hdf5.node HOT 14 CLOSED

Thanks, it works for me now, both the installation and dataset attributes reading.

from hdf5.node.

Yea anything that gives me an idea of what is going on would help; I will work on this project on the weekend(work days are loaded)

from hdf5.node.

It's an array of variable sized strings?

from hdf5.node.

Thank you so much @rimmartin for your work on this module and fast response.

Please find sample data attached and the output of reading attribute with group.getDatasetAttributes:

scada/active_power
{ initial_time: '�c@\u0003\u0001',
  time_step: '�`@\u0003\u0001',
  unit: '�w@\u0003\u0001' }

scada/generator_speed
{ initial_time: '��@\u0003\u0001',
  time_step: '',
  unit: 'P�@\u0003\u0001' }

Ok, we'll see over the weekend

from hdf5.node.

It's reading from your sample.h5 now. Thanks for it. I haven't published to npm yet; you can use "hdf5": "HDF-NI/hdf5.node", in your project's package.json to pull it from github. If you need it published I'll do it in the next couple of days.

from hdf5.node.

Thanks @rimmartin, experimental release is just fine.

Installation works on Linux and fails on OSX, probably because of the compiler flag required for "mac":

../src/h5_file.cc:201:22: error: extra tokens at end of #ifdef directive [-Werror,-Wextra-tokens]
#ifdef  H5_VERSION_GE(1,10,0)
                     ^
                     //
1 error generated.

from hdf5.node.

Ah that is something new I was adding for Single-Write-Multi-Read enabling for 1.10.x versions; I'll test on a mac tonight as well if it skips that code for 1.8.x version of node

from hdf5.node.

I commented the #ifdef H5_VERSION_GE(1,10,0) segement temporarily so it should build on darwin

from hdf5.node.

Thank you @rimmartin . I tested and got following output on Mac now:
