Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
argparse
-
Command line interface library
The most feature-rich C++ CLI library is CLI11. Other popular choices include Boost.ProgramOptions, argparse, cxxopts and others.

arg_router v1.2.0 - Thanks for all your feedback!
It was noted by u/k1lk1 that it wasn't entirely obvious what the benefits of this library are, so I'll compare arg_router to argparse, with a simple but common example.

What do you need to do to build a Linux terminal app for distribution?
You're looking for an argument parsing library. There are tons of these. My favorite is the excelent Rust crate called clap. For C++, the argparse library is a decent option.
- argparse v2.9 released - now with support for subcommands, nargs, prefix_chars, metavar, parse_known_args, improved help messages and more

palpatine Release1.0
p-ranav/argparse - A single-file header-only C++11 library for parsing command line arguments.

palpatine and rwar
I tried to make the code modular as much as possible. However, in main.cpp I have used the argparse and termcolor along with the main function. As Sam, pointed out, it would be a good idea to move them to a separate file and import them in main.cpp.

Looking for some small rust projects with an elegant code base that I can study.
argparse is another good one. Templated (delicious), tested, AND has conan and debian package deployment.

issue with pflag flagset
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.
-
xflags: An approach to command line flags with support for subcommands, positional args, environment variables, etc.
How does it compare to https://github.com/spf13/pflag ?
-
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.
