Printing variables

Recursive variable list may be printed to the terminal by the gna.parameters.printer module. The print_parameters(ns) function accepts the namespace to print:

from gna.parameters.printer import print_parameters
print_parameters( env.globalns )

The example output from the tests/bundle/detector_dbchain.py (line 98):

This example prints the variables of the bundlechain_v01 bundle:

1. Global namespace with

   1. 5 energy scale parameters: 1 fixed and 4 correction weights,

   2. 3 energy resolution parameters.

2. Three nested namespaces for the detectors AD11, AD21 and AD31 with

   1. IAV off-diagonal scale parameter,

   2. Linear scale correction.

The following columns are printed:

1. Variable name.

2. Current value.

3. Central value or [fixed].

4. Standard deviation.

5. Relative deviation if central value is nonzero.
