commandspec

Simple Rust macro for building std::process::Command objects. Uses macro_rules! and works on stable.

toml [dependencies] commandspec = "0.2.0"

Then:

```rust

[macro_use]

extern crate commandspec;

use commandspec::CommandSpec; // .execute() method on Command use std::process::Command;

command!( " cd path/location export RUSTLOG=full export RUSTBACKTRACE=1 cargo run {releaseflag} --bin {binname} -- {args} ", releaseflag=Some("--release"), binname="binary", args=vec!["arg1", "arg2"], )?.execute()?; // () on success (error code 0), CommandError for all else ```

Features:

• format-like invocation makes it easy to interpolate variables, with automatic quoting
• Equivalent syntax to shell when prototyping
• Works on stable Rust.
