Getting Started

Installation

Add wrapcli to your Cargo.toml:

cargo add wrapcli

Or add it manually:

[dependencies]
wrapcli = "0.1"

Basic Usage

use wrapcli::{run_streaming, WrapConfig};

fn main() -> std::io::Result<()> {
    let cfg = WrapConfig {
        orig_name: "rustc".into(),
        fake_name: "dustc".into(),
        fake_ver: "2.0.0".into(),
        save_orig: true,
    };

    let args: Vec<String> = std::env::args().skip(1).collect();
    let status = run_streaming(&cfg, args)?;
    std::process::exit(status.code().unwrap_or(1));
}

How It Works

When the wrapped tool outputs a line containing the original name, wrapcli intercepts it and applies rewriting rules:

1. The first occurrence of the original tool’s name and version is replaced with the fake name and fake version. If save_orig is true, the original version is appended in parentheses.
2. Any subsequent occurrences of the original name in usage lines are replaced with the fake name.

This ensures consistent output masking without breaking the tool’s functionality.
