Project description

inspectds

GitHub release (latest by date) CI

A CLI utility to print metadata of datasets in various formats (e.g. NetCDF, zarr, GRIB etc)

powered by xarray

Prerequisites

You need the following binary dependencies:

  • Python >= 3.9
  • Optionally, eccodes, which is necessary for GRIB support.

Installation

The recommended way of installation is pipx:

pipx install inspectds

# or if you want support for GRIB

pipx install 'inspectds[grib]'

If you want to install the latest development version from git, then use:

pipx install 'git+https://github.com/pmav99/inspectds.git#egg=inspectds[grib]'

Usage
