Charles LeDoux 9674738792 Apply environment expansion to options in .stowrc files ... Expand environment variables used in stowrc, as requested in https://savannah.gnu.org/bugs/?41826 This is achieved by creating a new function expand_environment() that replaces any substring of the form '$VAR' or '${VAR}' with contents of environment variable $VAR. Literal '$' can be given by '\$'. N.B. The function is only applied to the --target and --dir options, and only for options specified in .stowrc; cli options are left untouched. Undefined variables are expanded to the empty string, as they would be in normal shell parameter expansion. Unit tests added accordingly: - Test expand_environment(): * Expand $HOME * Expand ${HOME} * Expand ${WITH SPACE} * Expand '\$HOME'. Expected is '$HOME' * Expand ${UNDEFINED}. Expected is ''. - Test that it's applied to the correct options. - Test that CLI options are not expanded.		2019-06-25 19:38:26 +01:00
