[ANN] Configuration library

[Gerardo Oscar JT]

Maybe too simple, maybe there are several solutions, but here https://github.com/fulldump/goconfig is a configuration library to avoid the over-verbosity of flag library. It also allow load configuration from a json file.

It works like this:

type myconfig struct {
    Name      string `The name of something`
    EnableLog bool   `Enable logging into logdb`
    MaxProcs  int    `Maximum number of procs`
}

c := &myconfig{
    EnableLog: true,
}

goconfig.Read(c)

Goconf is very useful in my projects, maybe it could be useful for others too.

Oh my gosh! There are dozens of 'goconfig' projects at github and hundreds of 'configo' projects. This is crazy. I have been looking at some of them and probably fulldump/goconfig has the best logo :)  And also it is the most generic and simpler one with default values > json values > cli values precedence.

fun4all !!

Not trying to steal other's thunder, but just to provide yet another useful one for you to consider, 

For config via json or even environment variables (and many others more), take a look at

https://github.com/suntong/lang/tree/master/lang/Go/src/sys/CLI#017-jsonfilego

and

https://github.com/suntong/lang/tree/master/lang/Go/src/sys/CLI/027-global-redo

Not mine, but I myself found it most useful.

Wow incredible huge library with a lot of options, even with its own parser!

It is also possible to build hierarchical commands (like git)

I see that more like a thing to be human friendly, the human is constantly interacting with commands.

goconfig (well, this goconfig, there are 39 repositories called goconfig) is to cover easily the typical server

with a bunch of different config variables like the database, listening port, etc. and the option to load all

from a file. Attempting to be very simple to use and with code easy to read and understand.

Docopt seems awesome.

It's both awesome and scary how time flies.

It feels like only a few days since the first version of goconfig was released. I barely blinked a couple of

times, and here we are 10 years later.

Heh, mine's also stays stable. Excuse me for the hike, Gerardo :)

https://github.com/ohir/mopt

Package mopt provides zero-config command arguments parsing.
It is ready to use right after declaring a single mopt.Usage type variable (a string) containing
usage text to be printed with the '-h' flag. Can even be inlined with a Usage literal:

iterations := mopt.Usage("-n iterations, default: 9").OptN('n', 9)
