ncrystal-verify 4.2.4

Library for thermal neutron transport in crystals and other materials.

Verification tool for NCrystal installations

The ncrystal-verify package is non-binary package which is released along-side each release of NCrystal, with an identical version number. It provides a single command, ncrystal-verify, which can be used to validate that a particular installation of NCrystal is functional and produces expected results. In case of failure, ncrystal-verify ends with non-zero exit code.

Note that technically, the ncrystal-verify package depends on the ncrystal-python package with the same version number. Therefore, doing pip install ncrystal-verify should normally result in the appropriate version of ncrystal-verify being installed.

Examples of usage:

1. Launch with no arguments to require ALL tests to succeed. Tests that are missing optional dependencies will count as failures.

   $> ncrystal-verify
   

2. Only run tests with no missing dependencies. Those with missing optional dependencies will be reported as skipped, and will NOT count as failures.

   $> ncrystal-verify -m all
   

3. Get specific usage instructions:

   $> ncrystal-verify --help
