# osenv
|
||
|
|
|
||
|
|
Look up environment settings specific to different operating systems.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var osenv = require('osenv')
|
||
|
|
var path = osenv.path()
|
||
|
|
var user = osenv.user()
|
||
|
|
// etc.
|
||
|
|
|
||
|
|
// Some things are not reliably in the env, and have a fallback command:
|
||
|
|
var h = osenv.hostname(function (er, hostname) {
|
||
|
|
h = hostname
|
||
|
|
})
|
||
|
|
// This will still cause it to be memoized, so calling osenv.hostname()
|
||
|
|
// is now an immediate operation.
|
||
|
|
|
||
|
|
// You can always send a cb, which will get called in the nextTick
|
||
|
|
// if it's been memoized, or wait for the fallback data if it wasn't
|
||
|
|
// found in the environment.
|
||
|
|
osenv.hostname(function (er, hostname) {
|
||
|
|
if (er) console.error('error looking up hostname')
|
||
|
|
else console.log('this machine calls itself %s', hostname)
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
## osenv.hostname()
|
||
|
|
|
||
|
|
The machine name. Calls `hostname` if not found.
|
||
|
|
|
||
|
|
## osenv.user()
|
||
|
|
|
||
|
|
The currently logged-in user. Calls `whoami` if not found.
|
||
|
|
|
||
|
|
## osenv.prompt()
|
||
|
|
|
||
|
|
Either PS1 on unix, or PROMPT on Windows.
|
||
|
|
|
||
|
|
## osenv.tmpdir()
|
||
|
|
|
||
|
|
The place where temporary files should be created.
|
||
|
|
|
||
|
|
## osenv.home()
|
||
|
|
|
||
|
|
No place like it.
|
||
|
|
|
||
|
|
## osenv.path()
|
||
|
|
|
||
|
|
An array of the places that the operating system will search for
|
||
|
|
executables.
|
||
|
|
|
||
|
|
## osenv.editor()
|
||
|
|
|
||
|
|
Return the executable name of the editor program. This uses the EDITOR
|
||
|
|
and VISUAL environment variables, and falls back to `vi` on Unix, or
|
||
|
|
`notepad.exe` on Windows.
|
||
|
|
|
||
|
|
## osenv.shell()
|
||
|
|
|
||
|
|
The SHELL on Unix, which Windows calls the ComSpec. Defaults to 'bash'
|
||
|
|
or 'cmd'.
