[ANN] cli v0.6.0 — a small command-line library shaped like net/http

[MZA]

Hi all,

Introducing: https://github.com/mzattahri/cli

Most Go CLI libraries drift into frameworks: typed decoders, validation DSLs, config loading, tag-based declaration, shell-script generators,

CLI is an attempt at creating a library that stays in transport posture, the way `net/http` does:

1. route `argv` to a handler
2. give the handler a canonical way to read input and write output
3. expose the command tree for tooling
4. stop there.

The mapping is 1:1 with net/http: 

• `Handler` → `Runner`
  
• `Request` → `Call`
  
• `ResponseWriter` → `Output`
  
• `ServeMux` → `Mux`
  
• `Server` → `Program`
  
• `HandlerFunc` → `RunnerFunc`
  
• middleware wrapping → `MiddlewareFunc`
  

Typed values, validation, config parsing, optional positionals, and shell-script generation live in user code. Testability ships via a clitest sub-package that mirrors httptest. Introspection via Program.Walk (iter.Seq2[string, *Help]) for doc gen and custom tooling.

Still pre-1.0. Feedback welcome, especially on the Walk iterator and the middleware/composition surface.

Thanks!

"cli" is overused. It usually means "command line interface" for any number of different programs.

I also use it for little test clients, with the counterpart srv.

In your case, "climux" or "muxcli" would be more indicative of the use case your library appears to be addressing.

Best,

Jason

Fair point; agree it needs a better name.
