Compilation of tips and tricks

Config for flags

e.g.

• Have a config struct to contain the variables
• Use flag.<T>Var(*ptr) to link up the config to flags
• Call flag.Parse
• use the config as a global

Functional configuration

• You have a struct for your domain
• For each configurable field, create a option function
• You can pass these functions as a variadic argument. e.g. New(… Opts)
• (-) You have to write one for each parameter that you want to be able to configure
