Huge dependency graph

go mod graph | wc -l
     259

It transitively pulls in etcd, prometheus, protobuf and grpc. I believe this is all because of the warthog618/config library used in the commandline tools.

My poor little Raspberry Pi Zero W gets overwhelmed just trying to download everything.

Would you be open to a PR that converts to plain Go flag handling and removes that dependency?

[warthog618]

The use of config is more pervasive than you think - it is in the examples as well and also uses config files not just flags.
I have a couple of patches locally where I looked at switching to spf13/pflag and spf13/viper, as those are commonly used for configuration, but that makes the dependency situation worse:

go mod graph | wc -l
2371

I also considered using the standard Go flags for the tools, but the intent was to emulate the libgpiod command line and output as closely as possible and if I recall correctly that wasn't possible with the Go flags.

I recommend cross-compiling for your Pi Zero on a different platform - that is what I do.

Yeah, I started cross-compiling. Definitely much better.

fwiw, I've started migrating to alecthomas/kong. I really like it, and it's quite lightweight. And if you want config files, there's kong-hcl or kong-yaml.
