Add windows disclaimer and change int to Integer.

[lupemba]

I have tried to fix the issue I encountered with Int32, see issue #25

This does still not work completely since I am using Windows. I have therefore added a notice to the readme about the Windows support. It is easy to miss this when it is only written on GRIB.jl

@lupemba Thank you very much for the PR ! I took advantage of this to adapt the types for some other functions. This is actually legacy code from Cfgrib.jl that I didn't really double check.

Are you using GRIBDatasets.jl with GRIB.jl v4.0.0 ? Because I saw they added some support for windows, so this should be reflected here

Hi @tcarion,

I use the new version and I can see that they have added some windows support. The package tests still fails on windows because GRIB.Index is not defined for windows systems.

Yesterday I discovered that my issues is not with windows but instead that the .grib file has two longitude and two latitude dimensions. Two different grids in one file. I tried to remove the length check from getone(index::FileIndex, key::AbstractString) and was able to get the following out.

I am planning to make a new issue on this but I am just downloading a small file to reproduce it.

Mhm, I see. It should actually be possible to do without Index in GRIBDatasets.jl if we are on Windows, I don't think this should be difficult to do. I'll try when I have time :-)

Unfortunaltely, I think it's a untrivial issue to solve. I see 2 workarounds:

• Filter on each variable from GRIBDatasets.jl. For example: GRIBDataset(grib_path; filter_by_values = Dict("cfVarName" => "sst")). But this means you will need to treat each variable separately...
• Create 2 grib files separating the variables defined on distinct grids. But this requires a separate GRIB utility (like https://confluence.ecmwf.int/display/ECC/grib_filter)

Anyway, that'd be great if you can open an issue with a MWE :-)

Thank you for making the package @tcarion. It is nice that we now can work with grib files in Julia.

Anyway, that'd be great if you can open an issue with a MWE :-)

My download from ECMWF is still queued. I hope to create the issue on Monday.
