Crate clyops 

clyops — declarative CLI parsing. Behavior follows spec/SPEC.md.

use clyops::Cli;

let mut cli = Cli::new();
cli.arg("input", "Input file", "", "path");
cli.opt("PORT", "port", "p", "8080", "Server port").group("Network").rule("port");
cli.opt("VERBOSE", "verbose", "v", "flag", "Verbose output");
let args = cli.run();
println!("{} {} {}", args.str("input"), args.int("PORT"), args.bool("VERBOSE"));

Structs

ArgRef

Handle returned by Cli::arg for an optional rule on the same line.

Cli

A program CLI. Register options and arguments before parsing; registration errors panic.

OptRef

Handle returned by Cli::opt and friends for optional settings on the same line.

Values

Resolved values keyed by option var and argument name, in registration order.

Enums

Parsed

Outcome of Cli::parse.

Value

A resolved, typed value.

Functions

describe_rule

Help text for a validation rule (spec section 5).

die

Print an error and exit with code. Never suppressed.

error

Write an error message to stderr unless silent.

info

Write an informational message to stderr unless silent.

resolve_path

Resolve a path value against base (spec section 6).

set_silent

Suppress info/warn/error/success output (die and parse errors still print).

success

Write a success message to stderr unless silent.

validate

Validate value against rule and convert it to its typed form. The error is the spec’s error text.

warn

Write a warning to stderr unless silent.

wrap_text

Greedy word wrap that keeps existing line breaks (spec section 7).
