Package Exports
- path-env
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (path-env) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
path-env
Manipulate $PATH-like environment variable
Requirements
- Node.js ≥ 8.9.0
Usage
NOTE:
- Everything is chainable.
Modifying $PATH and get its value
import {pathString} from 'path-env'
const path = pathString()
.append(['/append/bin'])
.prepend(['/prepend/bin'])
.surround(['/surround/bin'])
.get.string()
console.log(path)This will print /surround/bin:/prepend/bin:...:/append/bin:/surround/bin in POSIX systems.
Modifying a $PATH-like and get its value
Modifying $NODE_PATH.
import {pathString} from 'path-env'
const path = pathString('NODE_PATH')
.append(['/append/node_modules'])
.prepend(['/prepend/node_modules'])
.surround(['/surround/node_modules'])
.get.string()
console.log(path)This will print /surround/node_modules:/prepend/node_modules:...:/append/node_modules:/surround/node_modules in POSIX systems.
Modifying $PATH-like property of env object
You can also modify $PATH-like value directly from an env-like object.
Signature:
import {pathEnv} from 'path-env'
const env = pathEnv() // equivalent to `const env = pathEnv(process.env, 'PATH')`
.path.append(['/append/bin'])
.path.prepend(['/prepend/bin'])
.path.surround(['/surround/bin'])
.get.env()
console.log(env)Result: env will looks exactly like process.env except modified PATH property.
