Package nfigure uses reflection to fill configuration structs from command line arguments, environment variables, and configuration files. The basic starts with NewRegistry(). Use functional args to control the set of fillers (environment, files, etc). Call Request() to add models (structs) that need to be filled out. Call ConfigFile() to add configuration files. Once that's done, call Configure() to actually fill the structs. For file fillers (filling from a configuration file), all data elements that are exported will be filled if there is a matching element in a configuration file. Disable filling an element by overriding its fill name to "-". The default set of supported tags are: With the default tags, the behavior of an exported struct field with no tags matches the behavior of explicitly setting tags like: That is to say that the field will be filled by a matching name in a configuration file, but it has no default and will not be filled from environment variables. The meta tag, (default is "nfigure") controls behavior: it provides a default name for recursion, controls if the first, or last value is taken if multiple fillers can provide values. It controls if a sub-struct should be descended into. By default, no command-line parser is included. The general form for the tag parameters for handlers and the meta control is tag:"name,key=value,flag,!flag". The name parameter, which is always first, specifies the name to match on. This overrides the field name. If you want to just use the field name, leave the name parameter empty. Do not skip it! A comma is good enough: The special value of "-" means to skip that filler entirely for this field. Boolean parameters can be specified after the name. The following all mean false: Likewise, "flag,flag=true,flag=1,flag=y" is highly redundant, setting flag to be true four times. Each filler defines it's own parameters. Here's a summary: Ultimately setting variables based on string values is done by https://pkg.go.dev/github.com/muir/reflectutils#MakeStringSetter See the documentation there for support for customer types. Known bugs / limitations: Combining of arrays, slices, and maps from multiple sources only works if all the sources are configuration files.
