envcfg is currently using commas as a separator when parsing multiple values from a default. It also requires that the number of values in a default exactly match the number of env_vars in the tag. This will break any default that needs to contain a comma.
For example:
type Foo struct {
DinerCall `env:"DINER_CALL" default:"Let's eat, grandpa"`
}
will break with the error:
envcfg: env tag DINER_CALL has 1 names but default tag Let's eat, grandpa has 2 values
envcfg should probably include a way to escape commas.
Right now it returns instantly, but that's inconsistent with other error handling in that loop.
An AWS client connection, for example, will be configured through multiple environment variables (AWS_ACCESS_KEY_ID
and AWS_SECRET_ACCESS_KEY
). We should support that.
