env_set¶

The module assigns any data within env. It is needed to provide an extra information to be saved with save-yaml and save-pickle.

The module provides three ways to input data:

Update env from a dictionary (nested), defined via YAML.

Write a string to an address within env.

Write parsed YAML to an address within env.

Positional arguments

update_yaml – define yaml input to update the dictionary

Options

-r, --root – define root environment

-a, --append – add custom fields to the output

-y, --yaml – add custom fields to the output (value parsed by yaml)

Examples

Optional argument -r may be used to set root address.

Write two key-value pairs to the ‘test’:
./gna \
    -- env-set -r test '{key1: string, key2: 1.0}' \
    -- env-print test
The first value, assigned by the key ‘key1’ is a string ‘string’, the second value is a float 1.
The -y argument may be used to write a key-value pair:
./gna \
    -- env-set -r test -y sub '{key1: string, key2: 1.0}' \
    -- env-print test
The command does the same, but writes the key-value pairs into a nested dictionary under the key ‘sub’.
The -a argument simply writes a key-value pair, where value is a string:
./gna \
    -- env-set -r test -a key1 string \
    -- env-print test
