- jina.hubble.requirements.expand_env_variables(line)[source]#
Replace all environment variables that can be retrieved via os.getenv. The only allowed format for environment variables defined in the requirement file is ${MY_VARIABLE_1} to ensure two things: 1. Strings that contain a $ aren’t accidentally (partially) expanded. 2. Ensure consistency across platforms for requirement files. Valid characters in variable names follow the POSIX standard and are limited to uppercase letter and number and the _ (underscore). Replace environment variables in requirement if it’s defined. :type line:
str
:param line: a line of a requirement file :rtype:str
:return: line
