Environment Variables
Config values may include references to environment variables. To substitute an environment variable into your value use
%(ENVVAR_NAME)s
When the variable has not been set you can assert a default value using the following format
%(ENVVAR_NAME:default_value)s
For example:
[LOG]
path = %(TEMP:./logs)s
file = %(LOG_FILE:pyxll.log)s
It’s possible to set environment variables in the [ENVIRONMENT]
section of the config file.
[ENVIRONMENT]
NAME = VALUE
For each environment variable you would like set, add a line to the [ENVIRONMENT]
section.
