Reading intslice from envFile

[bang9211]

I want to read IntSlice in .envFile

{9, 9, 8, 8, 7, 7}

so I typed in file space-seperated and comma-seperated like this, but it doesn't work.

TEST_VIPER_CONFIG_INTSLICE_VALUE1=9 9 8 8 7 7
TEST_VIPER_CONFIG_INTSLICE_VALUE2=9,9,8,8,7,7

GetIntSlice returns empty slice in these cases.

How can I read IntSlice from envFile?

and can I use GetStringSlice, GetStringMap, GetStringMapString, GetStringMapStringSlice in envFile??

I already know GetStringSlice uses space-seperated.
Plz let me know the envFile examples.

Thanks.
