Intended incompatibilities with npm run-script

• pqr runs only the specified script; npm also runs scripts with pre and post prefixes if they exist. Use [pqr prescript && ]pqr script[ && pqr postscript] for compatibility.

• pqr uses the nearest package.json it finds along the current path (./package.json, ../package.json, ../../package.json, …). npm uses a prefix consistent across all commands: the nearest directory containing either a package.json or a node_modules after first removing all node_modules components from the end of the current path.

• pqr adds arguments to the end of script commands with "$@"; npm double-quotes each argument after escaping only double quotes. (For example, npm run-script script -- '\"; yes #' will execute yes.)

• pqr runs the script with an unmodified environment; npm adds several of its own strings. (See npm run-script env.)

• pqr requires sh; npm will use %ComSpec% or cmd on Windows.

• pqr doesn’t include npm’s node-gyp-bin in PATH (because it doesn’t require npm to exist); find the directory with npm run env dirname '$(which node-gyp)' and run PATH=node-gyp-bin:$PATH pqr … for near-compatibility.

Running nested scripts with pqr

Create an npm wrapper that delegates to pqr if its first argument is run-script or run, and the original npm otherwise; add it to your PATH before the original npm.
