configfile

cmdr will try locating <appname>.{yml,yaml,json,toml} in current directory or these locations:

		predefinedLocations: []string{
			"./ci/etc/%s/%s.yml",       // for developer
			"/etc/%s/%s.yml",           // regular location
			"/usr/local/etc/%s/%s.yml", // regular macOS HomeBrew location
			"$HOME/.config/%s/%s.yml",  // per user
			"$HOME/.%s/%s.yml",         // ext location per user
			"$THIS/%s.yml", // executable's directory
			"%s.yml",       // current directory
		},

Once the major config file (<appname>.{yml,yaml,json,toml}) found in a location such as ABC, cmdr would try locating the child directory conf.d under ABC, and loading and merging all valid config files in this directory.

Run and test

So, run and test configfile with the following bash commands:

cd ./examples/configfile
go run . f -i 79 -i64=131 ~~debug | grep 'app\.config-file\.'

and these results should be printed:

app.config-file.bool                             => true
app.config-file.int                              => 9
app.config-file.string                           => string
app.config-file.updated                          => true

To show the value type info in the ~~debug output, uses ~~value-type:

cd ./examples/configfile
go run . f -i 79 -i64=131 ~~debug ~~value-type | grep 'app\.config-file\.'

The result is:

app.config-file.bool                             => true (bool)
app.config-file.int                              => 9 (int)
app.config-file.string                           => string (string)
app.config-file.updated                          => true (bool)
