Documentation

glob-env

Run multiple commands with variables determined by glob patterns.

Install

$ npm install -g glob-env

Usage

Running multiple instances of a script, for all combinations of "arch" and "lang" dirs:

$ glob-env arch="resources/arch/*" lang="resources/lang/*" -- npm run build-resources --lang $lang --arch $arch

Will run "npm run build-resources" for every combination. If, for example, the structure of "resources" is as follows:

  • resources/
  • resources/arch/*
  • resources/arch/x86
  • resources/arch/ia64
  • resources/lang
  • resources/lang/en_US
  • resources/lang/fr_FR

then the script will be run 4 times:

  • arch=arch/x86 lang=resources/lang/en_US
  • arch=arch/x86 lang=resources/lang/fr_FR
  • arch=arch/ia64 lang=resources/lang/en_US
  • arch=arch/ia64 lang=resources/lang/fr_FR

Using in pakcage.json

{
  "dependencies": {
    "glob-env": "^1.0.0",
    "browserify": "^13.0.1"
  },
  "scripts": {
    "build": "./node_modules/.bin/glob-env src=src/* ./node-modules/.bin/browserify src/${src} dist/${src}"
  }
}

Arguments

  • --parallel-run: commands will be executed concurrently
  • --sequential-run: commands will be executed one after the other (will take longer to complete, but require less resources)
  • --dont-collate-output: by default, command output is buffered to memory and displayed sequentially even if commands are executed in parallel. You should use this flag if process output is large
  • --dont-replace: don't replace $ variables in command line (env variables will still be set)
  • --: end of command-line flags. If present, following arguments will be passed to the executed command as-is.

Acknowledgements

This utlity was greatly inspired by glob-run which is really awesome.
