issue with pflag flagset
Just the bonus question: did I miss some hints when checking the https://github.com/spf13/pflag readme or the use case of FlagSet is indeed to just be used by cobra CLIs in subcommand only and not directly?
My understanding is that you can use pflag as a drop in replacement of the standard lib's flag (import flag "github.com/spf13/pflag"). So it can be used as a standalone lib I suppose.

Which packages do you recommend for building cli tools?
I realy enjoyed the patched version from spf13 with "--" support https://github.com/spf13/pflag

Define custom command-line flag types in Go 1.19
Nice, but Cobra (with pflag underneath) is so, so better.

-h --help -help help --? -? ????
Not by default on stdlib. There are libraries available though - https://github.com/spf13/pflag

Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
Flag functionality is provided by the pflag library, a fork of the flag standard library which maintains the same interface while adding POSIX compliance.

The flag package: strange but good?
spf13 has a drop in pflag that does the - short and -- long flags.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

akamensky/argparse: Argparse for Golang. Just because "flag" sucks!
What are the benefits of this package over the widely used spf13/pflag?
-
Go’s highly modular nature makes it particularly good for situations where requirements are changing or evolving.

Question: Custom argument parsing with flag ?
Nice to find that golang has this tool (I found only argparse adaptation https://github.com/akamensky/argparse). For me, as newcomer, flag is soooo basic. The reason why I still stick with it, because standard approach is more important for my use case, which is one layer upper than single language best parser. I am doing the same thing for various languages to make argument parsing be as easy as configuration change (if you are curious see https://github.com/ashlander/protoargs). That does not exclude potential Kong usage as an alternative backend at some point

What are some alternatives?
When comparing pflag and argparse you can also consider the following projects:
flag - Flag is a simple but powerful command line option parsing library for Go support infinite level subcommand
cobra - A Commander for modern Go CLI interactions
go-arg - Struct-based argument parsing in Go
kingpin - CONTRIBUTIONS ONLY: A Go (golang) command line and flag parser
go-flags - go command line option parser
docopt.go - A command-line arguments parser that will make you smile.
complete - bash completion written in go + bash completion for go command
Dnote - A simple command line notebook for programmers
flaggy - Idiomatic Go input parsing with subcommands, positional values, and flags at any position. No required project or package layout and no external dependencies.
