For a secure install, type the following from the command line (recommended):

gem cert --add <(curl --location --silent https://www.alchemists.io/gem-public.pem)
gem install log_plus --trust-policy MediumSecurity

NOTE: A HighSecurity trust policy would be best but MediumSecurity enables signed gem verification while allowing the installation of unsigned dependencies since they are beyond the scope of this gem.

For an insecure install, type the following (not recommended):

gem install log_plus

Add the following to your Gemfile:

gem "log_plus"

  • Rails Settings:
    • config.log_tags = Optional. Defines log output (all environments). Default: Timestamp and remote IP prefixes.
    • config.logger = Optional. Configures the Rails logger (all environments). Default: Logger.new (with 5MB max size and 7 files max rotation).
