In his classic book, Mastering Elliott Wave, Glenn Neely teaches his revolutionary approach to Wave theory, called NEoWave (advanced Elliott Wave). Continuously in print since its publication in 1990, this groundbreaking book changed Wave theory forever thanks to these scientific, objective, and logical enhancements to Wave forecasting. Step-by-step, Mr. Neely explains his advanced techniques and new discoveries.

sbprocess – A Minimal, Safe Wrapper Around Subprocesses (No Boilerplate)
rust programming cli devtools subprocess The Problem We've all been there. You just need to run a shell command, capture its output, handle errors gracefully, and maybe pipe a few things together. But the standard library's std::process::Command quickly becomes verbose:
cargo add sbprocess
// Run with environment cmd("python script.py") .env("DEBUG", "1") .current_dir("/app") .run()?;
// Capture both stdout and stderr separately let res = cmd("ls /nonexistent").run_unchecked(); println!("err: {}", res.stderr); use sbprocess::pipe; let result = pipe!("echo 'hello world'" | "wc -w").run().unwrap(); assert_eq!(result.stdout.trim(), "2"); With Timeout use sbprocess::cmd; use std::time::Duration; match cmd("sleep 10").timeout(Duration::from_secs(1)).run() { Ok(_) => println!("Finished"), Err(e) => println!("Timed out: {}", e), } Why Not Just Use std::process ? | Feature | std::process | sbprocess | |----------------------|--------------|------------| | String command | ❌ | ✅ | | Auto error messages | ❌ | ✅ | | Piping sugar | ❌ | ✅ | | Timeout | ❌ (manual) | ✅ | | Capture as String | ❌ (Vec ) | ✅ | Installation Add to your Cargo.toml :
